Fulltext Adult and Pediatric Lateral Lamella Cribriform Plate Height: In Need for a Comparative Study

Sakandar G, Haron J, Mohamad A, Mohamad I, Ramli RR

Allergy Rhinol (Providence), 2019 09 09;10:2152656719874775.
PMID: 31534825 DOI: 10.1177/2152656719874775

Surgery for sinuses has evolved with the advancement of instruments and modification in techniques. Endoscopes have expanded the surgical roles for lesions in the nose and para-nasal sinuses with reduced rate of complications and cosmetic side effects. Nevertheless sinus surgery in pediatrics patients has its own challenges. Pre-operative imaging is of paramount important especially when embarking on skull base procedures. The differences between adult and pediatric anatomy need to be further studied.

Objective and subjective changes in voice after endoscopic sinus surgeries in patients with and without nasal polyps

Wong EHC, Chong AW

Am J Otolaryngol, 2019 12 05;41(2):102367.
PMID: 31831185 DOI: 10.1016/j.amjoto.2019.102367

BACKGROUND: Many studies have looked at the effect of functional endoscopic sinus surgeries (FESS) on nasalance, nasal consonant and nasalized vowels. Only two studies investigated the effect of FESS on vocal sound quality and have not found statistically significant changes before and after operations. The aim of this study was to examine the short-term and long-term objective and subjective changes in the vocal quality of patients after FESS, comparing patients with and without nasal polyps.
METHODS: Sixteen patients were recruited for voice analysis during pre-operative, within two weeks and at least three months post-operatively. Subjective questionnaire was used to assess perception of voice changes.
RESULTS: There were no statistically significant changes in the acoustic parameters of patients with nasal polyposis. In patients with CRS without polyps, there was a statistically significant increase in fundamental frequency (F0) in nasal sound during early follow up. The changes in soft phonation index (SPI) values between the two groups were statistically significant during early follow-ups. Only patients with nasal polyposis perceived a subjective change in their voice post-operatively.
CONCLUSIONS: Clinicians should inform all patients, especially voice professionals about the possible effects of endoscopic sinus surgeries on their voice quality.

The creation and verification of cranial models using three-dimensional rapid prototyping technology in field of transnasal sphenoid endoscopy

Waran V, Menon R, Pancharatnam D, Rathinam AK, Balakrishnan YK, Tung TS, et al.

Am J Rhinol Allergy, 2012 Sep-Oct;26(5):e132-6.
PMID: 23168144 DOI: 10.2500/ajra.2012.26.3808

Surgical navigation systems have been used increasingly in guiding complex ear, nose, and throat surgery. Although these are helpful, they are only beneficial intraoperatively; thus, the novice surgeon will not have the preoperative training or exposure that can be vital in complex procedures. In addition, there is a lack of reliable models to give surgeons hands-on training in performing such procedures.

Fulltext Mucopyocele in the oral region: an unusual case

Telang , Ajay, Lahari, T., Chacko , James P.

Archives of Orofacial Sciences, 2011;6(2):1-4.
MyJurnal

Mucopyoceles are rare lesions defined as infected mucoceles. They have been reported only in the paranasal sinuses and appendix. Our case is the first to be reported in the oral region. A 58- year-old male presented with complaint of a painless swelling of two years duration in the right buccal sulcus with associated pus discharge. Radiographic examination ruled out pulpal and periodontal foci of infection and histopathology confirmed an underlying mucopyocele in the right buccal mucosa.

Orbital apex syndrome due to trigeminal perineural spread of sinonasal leprosy: a case report

El Beltagi AH, El-Nil H, Alrabiah L, El Shammari N

Clin Imaging, 2012 Mar-Apr;36(2):142-5.
PMID: 22370135 DOI: 10.1016/j.clinimag.2011.07.004

Leprosy is a granulomatous disease primarily affecting the skin and peripheral nerves caused by Mycobacterium leprae, but also significantly involving sinonasal cavities and cranial nerves. It continues to be a significant public health problem, and despite multidrug therapy, it can still cause significant morbidity. The awareness of cranial nerve, intracranial and orbital apex involvement as in our case is important for appropriate treatment measures.

Wahab Z, Tai E, Wan Hitam WH, Sonny Teo KS

Cureus, 2021 Mar 06;13(3):e13735.
PMID: 33842113 DOI: 10.7759/cureus.13735

INTRODUCTION: Nasopharyngeal carcinoma (NPC) is a tumor arising from the epithelial cells of the nasopharynx. NPC can spread and invade the base of skull, nasal cavity, paranasal sinuses, pterygopalatine fossa, and apex of the orbit. However, the involvement of the optic nerve in NPC is rare. The purpose of this case report is to report the efficacy of corticosteroid therapy in optic neuropathy secondary to NPC.
CLINICAL CASE: A 56-year-old Chinese woman, an active smoker, presented with a hearing deficit, persistent tinnitus and nasal congestion. Examination and investigations revealed the presence of a mass in the nasopharynx. Tissue biopsy revealed nasopharyngeal carcinoma. However, the Epstein-Barr virus was not tested. She was counseled for chemotherapy, but refused and was subsequently lost to follow up. She presented one year later with right eye ptosis associated with progressive worsening of diplopia and blurring of vision. Examination revealed multiple (second, third, fourth and sixth) cranial nerve involvement. Systemic examination and investigations revealed cervical lymphadenopathy and liver metastasis. Repeated imaging showed that the mass had invaded the base of the skull, cavernous sinus and orbital apices. Pulse dosing of corticosteroid therapy was commenced, resulting in dramatic improvement of vision.
CONCLUSION: Optic neuropathy may be the presenting sign of NPC. Corticosteroid therapy can offer immediate visual improvement.

Fulltext Supreme Nasal Turbinate as an Additional Surgical Landmark in Endoscopic Sinus and Skull Base Surgeries

Abdullah SN, Abdullah B

Cureus, 2020 May 15;12(5):e8132.
PMID: 32550052 DOI: 10.7759/cureus.8132

During endoscopic sinus and skull base surgeries, surgical landmarks are routinely used to guide surgeons navigating in the narrow corridor of the sinonasal region. Risk of complications is higher in difficult cases when there is excessive bleeding or alteration of the normal anatomical landmarks by tumour. An additional landmark is advantageous to prevent complications and serves as a guide. We present a case of supreme turbinate found incidentally during an endoscopic transsphenoidal surgery. Not much is known about the role of supreme turbinate. When it is present, the sphenoid ostium is located medial to its posteroinferior attachment, and behind its vertical part. Hence, the identification of this structure serves as an additional landmark besides superior turbinate during surgery.

Basaloid squamous cell carcinoma of the sinonasal tract with metastasis to the liver: a case report and literature review

Toe BP, Ramli N, Lam SY, Wong KT, Prepageran N

Ear Nose Throat J, 2015 Feb;94(2):E27-32.
PMID: 25651356

Basaloid squamous cell carcinoma (BSCC) is a rare subtype of squamous cell carcinoma. To date, only 95 cases of sinonasal BSCC have been reported in the English-language literature, and they account for 5% of all cases of head and neck BSCC. We describe what we believe is only the second reported case of a sinonasal tract BSCC that metastasized to the liver. The patient was a 36-year-old woman who presented with right-sided nasal obstruction and a foul-smelling discharge. Clinical examination and imaging identified a large, lobulated, enhancing mass in the right nasal cavity. Following excision of the mass, the patient was scheduled for radiotherapy. However, before it could be administered, follow-up imaging detected a metastasis to the liver and lung, and the patient was switched to chemotherapy. Initially, she responded well clinically, but at 5 months postoperatively, a follow-up CT showed an increasing metastatic presence in the liver and bone. The patient died of her disease 1 year after surgery.

Raman R, Prepageran N

Ear Nose Throat J, 2004 Apr;83(4):270.
PMID: 15147098

The authors describe a novel way of fashioning an endoscope holder from a common retractor and an ear speculum. Using such a device during endoscopic sinus surgery leaves both of the surgeon's hands free to manipulate the instruments.

PMID: 28194321 DOI: 10.3205/oc000055

Objective: To report an aggressive case of extranodal natural killer/T-cell lymphoma (NKTCL) of the ethmoid sinus presenting as orbital cellulitis Method: Case report Results: A 56-year-old male presented with right eye redness, reduced vision, and periorbital swelling for 5 weeks duration associated with a two-month history of blocked nose. The visual acuity of the right eye was 6/18. The eye was proptosed with periorbital oedema and conjunctival chemosis. The pupil was mid-dilated but there was no relative afferent pupillary defect. The fundus was normal. The extraocular movements were restricted in all directions of gaze. Nasal endoscopy revealed pansinusitis that corresponded with CT scan orbit and paranasal sinuses findings. Despite treatment, he showed no clinical improvement. Ethmoidal sinus biopsies performed revealed extranodal NKTCL. Further imaging showed involvement of the right orbital contents and its adnexa with intracranial extension into the right cavernous sinus and meninges over right temporal fossa. The patient underwent chemotherapy. However he succumbed to his illness two months after the diagnosis. Conclusion: Extranodal NKTCL is a great mimicker. This case demonstrated how an acute initial presentation of extranodal NKTCL can present as orbital cellulitis with pansinusitis.

Fulltext Pneumatization of Mastoid Air Cells, Temporal Bone, Ethmoid and Sphenoid Sinuses. Any Correlation?

Hindi K, Alazzawi S, Raman R, Prepageran N, Rahmat K

Indian J Otolaryngol Head Neck Surg, 2014 Dec;66(4):429-36.
PMID: 26396957 DOI: 10.1007/s12070-014-0745-z

The aim of this study is to assess the pneumatization of the paranasal sinuses (PNS) and other parts of temporal bone such as mastoid air cells and to investigate if there was any association between the aeration of these structures among the three major ethnic groups in Malaysia (Malay, Chinese, Indian) as this would be representative of Asia. A retrospective review of 150 computed tomography (CT) scans of PNS and temporal bones was done and analysed. The pneumatization of each area was obtained and compared using statistical analysis. Patients with a history of previous medical or surgical problems in the intended areas were excluded from the study. The pneumatization of the mastoid air cells and other temporal bone parts were noted to be symmetrical in more than 75 %. There was a positive correlation between the pneumatization of mastoid air cells and that of the sphenoid sinus. The prevalence of Agger nasi, Haller's and Onodi cells was observed to be significantly higher in the Chinese group. Preoperative assessment of the temporal bone and PNS with CT scan may be helpful in the evaluation of their anatomical landmark and decrease the possibility of surgical complications related to 3D structures.

Fulltext Endoscopic septoplasty: The open book method

Prepageran N, Lingham OR

Indian J Otolaryngol Head Neck Surg, 2010 Sep;62(3):310-2.
PMID: 23120731 DOI: 10.1007/s12070-010-0090-9

The advent of endoscopes has revolutionized rhinology and the traditional headlight based surgeries have largely been replaced by endoscopes. Septoplasty for deviated nasal septum or Sluder's neuralgia have been conventionally performed with the aid of headlight. This can be technically challenging as visualization of the nasal cavity, particularly the posterior portion is rather limited as the procedure is performed via the nostrils. In addition, with headlights for illumination, teaching this procedure can be difficult as only the surgeon who is wearing the headlights has direct vision of the surgical field.Endoscopic septoplasty is an accepted alternative to traditional headlight approach to septoplasty. This approach provides a direct-targeted route to the anatomic deformity, improved visualization, and magnification of the surgical field. Our experience in endoscopic septoplasty is highlighted in this paper, excluding septoplasties performed as part of exposure to the sinuses. We use the open book method that to best of our knowledge has not been described in literature before.

Loong SP, Afandi AN, Lum CL, Ong CA

Indian J Otolaryngol Head Neck Surg, 2019 Nov;71(Suppl 3):1692-1694.
PMID: 31763226 DOI: 10.1007/s12070-015-0945-1

Solitary extramedullary plasmacytomas are rare, discrete mass of neoplastic monoclonal plasma cells in the soft tissue with no evidence of multiple myeloma. They constitute 3 % of all plasma cell tumors and less than 1 % of head and neck malignancies. A 43 year old lady presented to our clinic with complains of diplopia and headache for 4 weeks. Computed Tomography scan showed a mass lesion in the sphenoid sinus eroding the sinus floor, right wall, basisphenoid and parasellar area. A biopsy of the mass reported as plasmacytoma. Systemic examination revealed no evidence of dissemination of the disease confirming the diagnosis of a solitary extramedullary plasmacytoma. The patient was subjected to 25 fractions of radiotherapy. Here, we report a rare case of solitary extramedullary plasmacytoma of the sphenoid sinus.

The Nasal Hemangioma

Tan SN, Gendeh HS, Gendeh BS, Ramzisham AR

Indian J Otolaryngol Head Neck Surg, 2019 Nov;71(Suppl 3):1683-1686.
PMID: 31763224 DOI: 10.1007/s12070-015-0918-4

Hemangioma is a disease of head and neck commonly, but its presence in the nasal cavity or sinus is rare. It is a form of benign tumour of vascular origin consisting of predominantly blood vessels. It can be categorized into capillary, cavernous and mixed type in accordance to its histopathology features. Retrospectively, we reviewed five cases of nasal hemangioma presenting at University Kebangsaan Malaysia Medical Center (UKMMC) between September 2007 and May 2015. Information on the patients age, gender, ethnicity, clinical symptoms, imaging findings (if available), treatment modalities were collected retrospectively for analysis. Five patients were analysed. Females were more affected than male with ratio of 4:1. All patients presented with unilateral lobular capillary hemangioma of the nasal cavity with 60 % (3/5) of the lesions on the right side and 40 % (2/5) on the left side. The common symptoms at presentation were epitaxis and nasal obstruction (5/5, 100 %), followed by rhinorrhea (3/5, 60 %) and facial pain (1/5, 20 %). All the patients underwent a surgical excision of the hemangioma. The five patients had no recurrence on subsequent follow ups. Computed tomography of paranasal sinuses can be performed to exclude bony erosions. Endoscopic sinus haemangioma excision provide good visualisation and better outcomes. In conclusion, nasal hemangioma should always be differential diagnosis for nasal lesions and surgical excision is still the preferred first line treatment.

Ameen SA, Salina H, Zahedi FD, Primuharsa-Putra SH, Masir N

Iran J Otorhinolaryngol, 2019 May;31(104):191-195.
PMID: 31223601

Introduction: Angiomyolipoma (AML), a benign mesenchymal tumor that commonly arises from the kidney, may be associated with tuberous sclerosis complex and perivascular epithelioid cell tumors (PEComas). Nasal angiomyolipoma is very rare and usually occurs in elderly individuals with epistaxis and nasal obstruction.
Case Report: We report a rare case of nasal angiomyolipoma in a young male. To the best of our knowledge, this is the first documented case of angiomyolipoma originating from the posterior end of the inferior turbinate, clinically mimicking juvenile nasopharyngeal angiofibroma (JNA). The tumor was removed completely via coblator-assisted endoscopic sinus surgery. The patient was asymptomatic at a 2-year follow-up.
Conclusion: Nasal AML located in the posterior nasal cavity in a male patient can mimic the presentation of JNA. A computed tomography scan of the paranasal sinuses played an important role in differentiating nasal AML from JNA. The coblator-assisted endoscopic technique is useful in controlling intraoperative hemostasis in the removal of a suspicious vascular tumor.

Fulltext Epiphora as the primary initial presentation for a huge sino-nasal osteoma: a rare presentation

Nadia Yaacob, Adil Hussein

Journal of Biomedical and Clinical Sciences, 2018;3(2):26-28.
MyJurnal

Sino-nasal osteoma is a common benign tumour of paranasal
sinuses and usually asymptomatic. Here, we presented a case of a huge sinonasal osteoma. Despite the large size of the tumour, the only presentation
was epiphora. There were no headache, facial pain or diplopia. Nasal
obstruction only occurred after involvement of the nasal cavity. In diagnosing
aetiology of the epiphora, sino-nasal pathology needed to be ruled out after
excluding ocular causes. Multidisciplinary approach between otolaryngology
(ORL) team and ophthalmology team was essential in managing the case.
The tumour was successfully removed surgically via endoscopic approach;
and dacryocystorhinostomy (DCR) was performed to alleviate the epiphora.

Ng, WL, Umi Kalthum MN, Jemaima CH, Norshamsiah MD

Journal of Surgical Academia, 2016;6(1):43-45.
MyJurnal

Frontal mucocele is not commonly masked as upper lid abscess.A 72-year-old Chinese man with underlying hyperthyroidism complained of left upper eyelid swelling of 6 months duration. The swelling had persisted and worsen when intravenous antibiotic was changed oral type. Visual acuity on presentation was hand motion and reverse relative afferent pupillary defect was present. Because the swelling was large and resulted in mechanical ptosis and ophthalmoplegia, a CT imaging was performed, which showed huge left frontal mucocele eroding the supereromedial orbital rim. The left globe was displaced inferolaterally but there was no extension into brain parenchyma. Fundus examination showed pale optic disc with dull macula. Old laser marks were seen at peripheral fundus. Referral to ortholaryngologist was made and endoscopic sinus surgery and evacuation of mucopyocoele was done. Culture and sensitivity of the fluid showed no organism. He recovered well postoperatively with additional two weeks of antibiotics. We highlight the necessity of surgical drainage of mucocele, following a course of antibiotic.

Fulltext Severe orbital cellulitis secondary to chronic sinusitis: challenges in saving the eye

Diymitra, K. G., Mushawiahti, M., Aida Zairani, M. Z.

Journal of Surgical Academia, 2018;8(1):47-50.
MyJurnal

Orbital cellulitis is a relatively common disease affecting predominantly the paediatric population. Most cases occur as a result of spread from the nearby sinuses. Other causes include penetrating trauma or extension from infected adjacent structures.If left untreated, this condition may result in devastating sequelae such as orbital apex syndrome, cavernous sinus thrombosis, meningitis, cranial nerve palsies, intracranial abscess formation and even death. A 47 year old immunocompetent Burmese lady presented with left eyelid swelling of 2 days duration associated with eye redness, blurring of vision and diplopia. Previously, there was history of right maxillary sinusitis and parapharyngeal abscess 9 months prior to presentation. On examination, she was afebrile with vision of 1/60 for the left eye with positiverelative afferent pupillary defect (RAPD). The eye was proptosed and swollen with restricted extraocular movements in all gazes. Conjunctiva was injected with chemosis and there was corneal epithelial bedewing. Otherwise anterior chamber was quiet and intraocular pressure was 51mmHg. Bilateral fundus examination was normal. Computed tomography (CT) scan of the orbit and paranasal sinus showed dense sinusitis and periosteal abscess at the lateral orbital wall.She was started on intravenous (IV) Cefuroxime and Metronidazole and underwent Functional Endoscopic Sinus Surgery (FESS) and orbital decompression. Intra-operatively there was pus and debris at the left anterior ethmoid, maxillary and sphenoid air sinuses and cultures revealed Klebsiella pneumoniae which was sensitive to Cefuroxime. Despite medical and surgical treatment, left orbital swelling only reduced minimally. However after starting intravenous Dexamethasone the swelling dramatically improved. She completed 10 days of intravenous Dexamethasone. Upon discharge, she was given oral Dexamethasone 2mg daily for 2 weeks and completed 2 weeks of oral Cefuroxime and Metronidazole. Intraocular pressure normalised and vision recovered to 6/9. A repeat CT orbit 3 weeks later showed resolving preseptal and periorbital collection.

Fulltext The Clinical and Radiological Characterizations of the Allergic Phenotype of Chronic Rhinosinusitis with Nasal Polyps

Abdullah B, Vengathajalam S, Md Daud MK, Wan Mohammad Z, Hamizan A, Husain S

J Asthma Allergy, 2020;13:523-531.
PMID: 33149624 DOI: 10.2147/JAA.S275536

Purpose: The allergic phenotype of chronic rhinosinusitis (CRS) and central compartment atopic disease (CCAD) have been described. The CCAD is a radiological phenotype in patients with CRS that presents as a central mucosal disease due to allergy. The subset of patients having chronic rhinosinusitis with nasal polyps (CRSwNP) has not been well characterized. We aim to describe the clinical and radiological characterizations of patients presenting with the allergic phenotype of CRSwNP.
Patients and Methods: A cross-sectional study at a tertiary hospital was performed. Adult patients diagnosed with CRSwNP who had both allergology and radiological assessments were enrolled. The symptoms of allergic rhinitis, Lund-Kennedy (LK) endoscopic scoring, Lund-Mackay (LM) computed tomography scan of paranasal sinuses (CTPNS) scoring, CCAD features, skin prick test (SPT) and level of specific IgE were assessed. All the patients underwent SPT for house dust mites.
Results: A total of 38 patients were enrolled. Symptoms, endoscopic and CTPNS scores were higher in the allergy and CCAD groups compared to the nonallergy and nonCCAD groups. The symptom of "need to blow nose" was statistically significant in allergy vs nonallergy (p=0.01) and CCAD vs nonCCAD (p=0.02). There were significant differences in the endoscopic scores in both allergy and CCAD (allergy vs nonallergy, p=0.01; CCAD vs nonCCAD, p=0.03), and CT scores in both allergy and CCAD (allergy vs nonallergy, p=0.02; CCAD vs nonCCAD, p=0.02). All patients with CCAD have worse scoring than nonCCAD (LK score, p=0.03; LM score, p=0.02). Patients with allergy have more polypoidal involvement of the middle turbinates (left middle turbinate, p=0.141; right middle turbinate, p=0.074) and CCAD (left middle turbinate, p=0.017; right middle turbinate, p=0.009) than nonallergy and nonCCAD patients.
Conclusion: Allergic phenotype of CRSwNP has a worse clinical and radiological disease burden. Optimal treatment of allergy is essential for a better outcome.

Husain S, Amilia HH, Rosli MN, Zahedi FD, Sachlin IS, Development Group Clinical Practice Guidelines Management of Rhinosinusitis in Adolescents & Adults

Malays Fam Physician, 2018;13(1):28-33.
PMID: 29796207 MyJurnal

Rhinosinusitis is a common health problem encountered in primary care. It is due to mucosal inflammation of the nose and paranasal sinuses. Less than 2% of the cases are associated with bacterial infections. Diagnosis is based on clinical symptoms and supported by nasal endoscopy and imaging studies. Intranasal corticosteroids and normal saline irrigation are important treatments. Antibiotics are seldom indicated.
