    Nasal polyposis (NP) has a great impact on quality of life (QOL) and its management involves a combination of medical therapy and surgery. To the authors' knowledge, no publication has extensively examined NP after optimal medical treatment based on subjective evaluations. The aim of this prospective study was designed to evaluate the QOL in NP patients after (1) a short course of oral steroids, (2) initial 3-month course of macrolide, and (3) long-term treatment with intranasal steroids. A total of 55 patients with grades I and II NP were consecutively treated with oral prednisolone at 25 mg in a single dose for 2 weeks, macrolide at 250 mg daily for the first 3 months, and long-term intranasal steroids. Patients were followed up and evaluated at baseline and 3, 6, and 12 months for QOL measure. At baseline, patients with grade I and grade II NP showed significantly worse QOL scores on all Rhinosinusitis Disability Index domains, particularly for physical function (4.59 ± 1.41) and were significantly higher in social function (3.16 ± 1.17). At 3, 6, and 12 months of treatment, patients showed a significant improvement in all impaired QOL domains compared with baseline after optimal medical therapy (p < 0.05). These results suggest that the optimal medical treatment to improve QOL incorporates medical polypectomy with a short course of oral steroids in addition to macrolide and this can be maintained by long-term intranasal steroid therapy.

    Allergic rhinoconjunctivitis denotes both nasal and ocular manifestation of allergy, which may be solely treated with intranasal steroid. This study compares the efficacy of mometasone furoate nasal spray (NS) and fluticasone furoate NS in treatment of allergic rhinoconjunctivitis. The secondary objective is to study the severity of baseline ocular symptoms in allergic rhinoconjunctivitis. Seventy-eight patients with allergic rhinoconjunctivitis were assessed subjectively and objectively using twice-daily symptom scores for nasal (reflective total nasal symptom score [rTNSS] and instantaneous TNSS [iTNSS]) and ocular (reflective total ocular symptom score [rTOSS] and instantaneous TOSS [iTOSS]) symptoms, rhinoconjunctivitis quality-of-life questionnaires (RQOLQs), and acoustic rhinometry. All measurements were taken at baseline and at 4 and 8 weeks of treatment. Sixty-three patients who were randomized into the mometasone furoate group (n = 36) and the fluticasone furoate group (n = 27) completed the study. Seventy-six percent of patients had mild ocular symptoms, 20.5% had moderate symptoms, and only 2.6% had severe symptoms at baseline based on the iTOSS; 65.1% had mild nasal symptoms and 3% had severe nasal symptoms. There was significant reduction in the symptom scores after 1 week (p < 0.05). Both groups had significant improvement in RQOLQ scores after 1 month, which further improved at 2 months (p < 0.05). The nasal dimensions also improved in both groups (p < 0.05) but there was no statistically significant difference between groups. Both mometasone furoate and fluticasone furoate are effective as single-modality treatment of allergic rhinoconjunctivitis. The majority of patients manifest mild ocular symptoms that may be solely treated with intranasal steroids.

    Antrochoanal polyps are a rare clinical entity. In this review of patients treated between January 1996 and September 2002, there were 18 cases of antrochoanal polyps. The mean age of patients was 20 years. Nasal obstruction was the most common symptom (17 cases, 94%), followed by rhinorrhoea (44%), epistaxis (33%), postnasal drip (28%), and snoring (22%). Chronic sinus was the most common associated rhinological finding (50%). Various surgical approaches were used: endoscopic polypectomy and middle meatal antrostomy in seven patients (38.9%), endoscopic polypectomy and inferior meatal antrostomy in three patients (16.7%) and Caldwell-Luc surgery in one patient (5.6%). No complications were noted in patients treated with powered instrumentation, including the three patients in whom combined transcanine approaches were used. We concluded that powered endoscopic polypectomy was safe and effective. It allowed a more complete dissection and may diminish the chance of recurrence.

    BACKGROUND: Embozene® is a new neuroembolizing microsphere used to reduce intraoperative bleeding for head and neck tumours. We report a case of iatrogenic ophthalmic artery occlusion after Embozene® embolization of the external carotid artery (ECA).

    CASE PRESENTATION: A 22-year-old African gentleman presented with left nasal obstruction and epistaxis for 2 years and was diagnosed with nasopharyngeal carcinoma. He subsequently underwent embolization of the maxillary branch of the left ECA using Embozene® Microspheres - 250 μm in size before endoscopic tumour excision to reduce intra-operative bleeding. He complained of sudden painless profound visual loss in the left eye (LE) two hours after embolization. Visual acuity in LE was no light perception. Fundus examination showed pale retina with no cherry red spot. Arterial narrowing and segmentation were seen in all quadrants. A diagnosis of left ophthalmic artery occlusion was made. Despite immediate management including ocular massage and lowering of intraocular pressure, the visual loss remained. Retrospective review of digital subtraction angiogram showed an anastomosis between the left ophthalmic artery and anterior deep temporal artery as a potential route for microspheres migration.

    CONCLUSION: Pre-operative angio-architecture understanding and diligent selection of embolic material are helpful in preventing this adverse event. The use of newer agents for embolotherapy may cause migration of embolic material from the external to the internal carotid system leading to ophthalmic artery occlusion and blindness.

    Graft selection remains the greatest challenge for surgeons performing rhinoplasty. The preferred choice thus far for nasal reconstruction would be autograft compared to allograft due to its lower rate of infection and extrusion as it does not induce an immune response. We have evaluated 26 patients who underwent open structured rhinoplasty at our center and compared our experience regarding the operative technique, graft availability, indications, and limitations. The racial distribution was 18 Indians, 5 Chinese, and 3 Malays with a mean age, hospitalization, and followup of 30.5 years, 16.9 months, and 4.4 days, respectively. Majority of the patients (57.6%) presented with twisted nose and 30.7% of the patients presented with history of nasal trauma. All the patients had deviated septum of varying severity. The most common graft used was quadrangular cartilage graft and the common complications noted were ala deformity and tip anaesthesia in 7.6% patients respectively.

    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.

    Sinus surgery has the potential of allowing ENT surgeons to encroach the boundaries of our colleagues in ophthalmology and neurosurgery. The advent of nasal endoscope and lately powered instrumentation and computer-assisted navigational systems has avoided the use of the conventional and more radical approaches by the ENT surgeon for the treatment of inflammatory pathology or tumors of the orbit and skull base. As rhinologists have gained more experience in endoscopic surgery, more areas related to the orbit and the anterior skull base are accessible and surgery is safer.

    Nasal irrigation is an effective and cheap method in managing post sinonasal surgery patients. It works by improving ciliary clearance and performing mechanical debridement of the thick crust, decreasing mucosal edema and reducing the inflammatory mediators. Presence of nasal irrigation bottle contamination and its effect on patients have been studied. The aim of this study is to prospectively identify the risk of contamination in the nasal irrigation bottle, fluid from the bottle and to correlate with endoscopic findings from the patients who had underwent sinonasal surgery. Swabs will be taken from the nasal irrigation bottle and patient's middle meatus before the surgery and at each post surgery visits (2 and 4 weeks). Patients will be advised to irrigate their nose three times per day post sinonasal surgery. During endoscopic examination of the patient's nasal cavity at 2 and 4 weeks, any evidence of infection will be noted and documented. Additionally, a swab of fluid irrigated from the nasal cavity collected during the clinic follow-ups will also be taken. The specimens will be sent to the Microbiology laboratory for standard culture and sensitivity test. A total of 27 patients completed the study and were divided into case (n = 15) and control (n = 12) groups. The CFU (colony-forming unit) value of the bacteria cultured from the nasal cavity and the nasal irrigation bottle was statistically significantly (P = 0.00) increased from the baseline to the second week follow-up in both groups but not from the second week to the fourth week follow-up. The majority of the swabs from the nasal cavity of the patients and the nasal irrigation bottles were positively cultured for Pseudomonas sp. group. Other groups of bacteria that were cultured were Enterobacter sp., Coagulase Negative Staphylococcus (CONS) and Klebsiella sp. Endoscopically, there was no clinical evidence of infection found in the nasal cavity of the patients. The nasal irrigation bottle that was used in the post sinonasal surgery treatment and for alleviation of symptoms of sinonasal diseases was found to have bacterial contamination from the swabs taken from the bottle. However, despite this finding there was not clinical evidence of infection noted from the nasal endoscopic examination. A simple and effective method of cleaning the bottle would be helpful to reduce the bacterial contamination for this useful treatment method.

    Esthesioneuroblastoma is a rare malignant neoplasm of oflactory neuroepithelium and usually located at the olfactory cleft at superior nasal cavity. Ectopic localization of esthesioneuroblastoma is even rarer and usually posed with a diagnostic dilemma and delay in the diagnosis and management, We report a rare case of ectopic esthesioneuroblastoma of the sphenoclivus with the presentation of intermittent unilateral epistaxis, intermittent intractable headache without anosmia. Nasal endoscopy findings showed a pulsatile mass at the anterior face of the sphenoid sinus with extension posteriorly towards the clivus region and occupying the floor of the sphenoid sinus. Endonasal transclival endoscopic excision of tumour was performed which involved otorhinolaryngology surgeon and neurosurgeon with intraoperative navigation imaging and frozen section. The histopathological findings was esthesioneuroblastoma. Due to its rarity and unusual presentation, the diagnosis of ectopic esthesioneuroblastoma is difficult and can be misdiagnosed with the other type of malignancy. Therefore, the histopathological result is important in confirming the type of tumour and can lead to the next step of management.

    Osteoradionecrosis is one of the most serious complications of radiotherapy for nasopharyngeal carcinoma. We report three cases of osteoradionecrosis in temporal lobe who presented differently few years after completion of radiotherapy. Cranial magnetic resonance image showed lesions in temporal lobe either unilateral or bilateral with mass effect. One of the cases even showed disease progression few years after the initial diagnosis of osteoradionecrosis. Diagnosis of osteoradionecrosis for all three patients was confirmed by biopsy.

    A prospective single blinded interventional study was held in Otorhinolaryngology Clinic, Universiti Kebangsaan Malaysia Medical Centre in August 2010 until November 2012 to evaluate the functional outcome of septorhinoplasty objectively and subjectively. Objective assessment was done using rhinomanometry and subjective assessment using Nasal Obstruction Symptoms Evaluation (NOSE) scale and Health-Related Quality of Life Questionnaires (HRQOL) in Rhino Surgery. All measurements were taken preoperatively and 3 months postoperatively. A total of 29 patients were enrolled and completed the study. Septorhinoplasty was commonly performed in Malays and Indians and rare amongst Chinese, with age ranged from 18 to 54 years. Majority had no history of trauma. Twisted nose was the most common external nose abnormality followed by crooked and saddle nose. All patients had internal valve insufficiency. There were significant improvement of the total and of all the parameters in the NOSE scale post septorhinoplasty (p  0.05). Significant correlations were noted in the improvement between the two subjective assessments (NOSE scale and HRQOL score). However, there was no significant correlation in the improvement between the subjective (NOSE scale and HRQOL score) with objective (rhinomanometry score) assessments. Septorhinoplasty improves the nasal airflow and quality of life of patients with nasal obstruction.

    Foreign body aspiration in children is a problem that can lead to several complications, including death. In this retrospective publication review from 1970 to 2015, there were altogether 42 Malaysian children below the age of 15 y reported with foreign body (FB) ingestion. There were 31 boys and 11 girls between 2 and 177 mo of age. The incidence of FB ingestion in children varied with dietary practices. Peanut was the most common food-related substance inhaled followed by watermelon seed and coconut kernel. The most common non-food related substances were metal objects (toys, springs, hair clips) and plastic objects (ballpoint tips, pencil caps and whistles). Successful removal of FB by bronchoscopy is achieved in the vast majority of cases except for a case of impacted whistle inhalation and a neglected laryngeal FB which required a tracheostomy. One child required thoracotomy for the removal of a peanut in the right bronchus. The incidence of food-related substance inhalation was more common than non-food related substance (30:7). From this review, the key messages are two: first, prevention can be achieved by educating parents not to allow access to small objects or dangerous foods to children below 3 y age; Second, emergency first aid home measures, in the combination form of back blows in the head down position and chest or abdominal thrusts, should be early performed according to the pediatric age group and can be quite effective.

    Introduction: Sniffin' Sticks smell identification test is a tool used for evaluation of olfactory function but the results are culture-dependent. It relies on the subject's familiarity to the odorant and descriptors. This study aims to develop the Malaysian version of Sniffin' Sticks smell identification test suitable for local population usage.

    Materials and Methods: The odorant descriptors and distractors of the original version of Sniffin' Sticks were translated into Malay language. It was then tested for familiarity and identifiability in 30 normosmic subjects. The descriptors were replaced until the familiarity of all descriptors and identification rates of odorants achieved ≥ 70%. The validity of the new cultural-adapted version was tested in 60 hypo-anosmic subjects and 60 normosmic subjects with Student t-test. The test-retest reliability was evaluated after two weeks with interclass correlation.

    Results: Two odorant descriptors and nine distractors achieved familiarity <70% (13.3% - 66.7%) and were replaced. Another three culturally inappropriate distractors were also replaced. The mean score among the healthy subjects was significantly higher than the subject with smell dysfunction [13.7 (1.12) and 7.3 (3.42); t = 7.24 (df = 34.23), P<0.001]. The coefficient of correlation (r) between test and retest scores was 0.93 (P<0.001).

    Conclusion: The cultural adapted Malaysian version of Sniffin' Sticks smell identification test is valid and has high test-retest reliability. This is the first smell identification test validated in Malaysia. It is effective for evaluation of olfactory function in local population.

    Juvenile angiofibromas (JAs) are well-characterised in literature, arising typically in the posterolateral wall of the nasal cavity of young males. Numerous theories have been proposed to explain the occurrence of this unique and rare tumour. Angiofibromas originating in other sites within the head and neck have been described but this is exceedingly rare, constituting less than 2% of all diagnosed cases. Extranasopharyngeal angiofibroma is a rare lesion, and more importantly, controversial. It is not known whether it is actually a relative of the well-known JA that is seen exclusively in adolescent males. We present the case of a post-menopausal woman with unilateral nasal obstruction who was unexpectedly diagnosed as nasal septal angiofibroma.

    Primary nasal lymphomas are rare. One of the most common cellular subtypes in the Asian population is natural killer (NK)/T-cell lymphoma (NKTL) with a high association of EBV. We report a case of a 42-year-old female, who presented with a worsening sore throat, odynophagia, dysphagia to solid food due to oropharyngeal ulcers and bilateral nasal blockage and recurrent fever for the past two weeks prior to admission. Physical examination revealed ulcers over the soft palate with nasopharyngeal slough. Computerized Tomography (CT) scan of the neck showed nasopharyngeal abscess with bilateral maxillary ethnoidal sinusitis. The diagnostic and management challenge is discussed.

    The purpose of this study was to determine the spectrum of nasal involvement in systemic lupus erythematosus (SLE) and its association with the disease activity of SLE based on the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). This was a cross-sectional and observational study involving 73 stable SLE patients. All subjects were evaluated for the SLEDAI scores and had nasal endoscopic examination. The most commonly reported symptom was nasal congestion (31.5%) followed by nasal itchiness (26.0%), runny nose (20.5%) and nasal dryness (19.2%). Almost half (42.9%) of the subjects had nasal mucosal abnormalities, which included mucositis, crusting, ulceration, bifid middle turbinate, septal spur, Jacobson's organ, deviated nasal septum, bilateral inferior turbinate hypertrophy, everted uncinate process, nasopharynx cleft and torus palatinus. The median SLEDAI score for subjects with nasal symptoms was significantly higher than subjects without nasal symptoms (p
