Fulltext Experience with sublabial transseptal transsphenoidal hypophysectomy at the Universiti Kebangsaan Malaysia

Said H, Cheah F, Mohamed AS, Hadi AR

Med J Malaysia, 1993 Jun;48(2):222-4.

The transseptal transsphenoidal hypophysectomy has become a relatively frequent procedure in recent years. We performed 20 such procedures between January 1984 and December 1987 for various pituitary disorders. Significant complications such as CSF rhinorrhea, meningitis, diabetes insipidus, haemorrhage and septal perforation are discussed. The mortality rate for the series was 5%. In analysing the data, we feel that this technique of hypophysectomy is a safe procedure.

J Laryngol Otol, 2003 Dec;117(12):969-72.

PMID: 14738607

Plain X-rays, computed tomography (CT) and magnetic resonance imaging (MRI) scans performed for non-ENT reasons often reveal incidental sinus mucosal changes. These changes need to be correlated clinically before diagnosing rhinosinusitis. This study examined the prevalence of such changes in MRI scans in children up to age 16. Scans were scored using an adapted Lund-Mackay classification and were positive when one or more sinuses showed abnormalities. Randomly selected scans in the retrospective arm revealed a prevalence of 20 of 62 (32.3 per cent). In the prospective arm 45 of 60 children were defined as truly asymptomatic, of which 14 scans (31 per cent) were positive. Other studies in adults and children using CT and MRI report a prevalence range of roughly 30 to 45 per cent. This variability may be attributed to differences of study design, definitions of population age, definitions of asymptomatic and definition of abnormal sinus. Other plausible factors to explain regional differences are climate and frequency of upper respiratory tract infections.

PMID: 15513020

A sphenoid mucocele often presents late due to its deep-seated anatomical site. It has a varied presentation, due to its close relationship to the cavernous sinus and the base of the skull. It can present initially to the ophthalmologist with ocular complaints. In the present paper, the authors present two cases of sphenoid mucocele, one with an isolated third and one with an isolated sixth cranial nerve palsy.

PMID: 16354338

The purpose of this retrospective study is to determine the pattern of cerebrospinal fluid (CSF) rhinorrhoea presenting to our tertiary referral centre in Kuala Lumpur and to assess the clinical outcomes of endonasal endoscopic surgery for repair of anterior skull base fistulas. Sixteen patients were treated between 1998 and 2004. The aetiology of the condition was spontaneous in seven and acquired in nine patients. In the acquired category, three patients had accidental trauma and this was iatrogenic in six patients (five post pituitary surgery), with one post endoscopic sinus surgery (ESS). Imaging included computed tomography (CT) scan and magnetic resonance imaging (MRI). Endoscopic repair is less suited for defects in the frontal sinuses with prominent lateral extension and defects greater than 1.5 cm in diameter involving the skull base. Fascia lata, middle turbinate mucosa, nasal perichondrium and ear fat ('bath plug') were the preferred repair materials in the anterior skull base, whereas fascia lata, cartilage and abdominal fat obliteration was preferentially used in the sphenoid leak repair. Intrathecal sodium flourescein helped to confirm the site of CSF fistula in 81.3 per cent of the patients. Ninety per cent of the patients who underwent 'bath plug' repair were successful. The overall success rate for a primary endoscopic procedure was 87.5 per cent, although in two cases a second endoscopic procedure was required for closure. In the majority of cases endoscopic repair was successful, and this avoids many of the complications associated with craniotomy, particularly in a young population. Therefore it is our preferred option, but an alternative procedure should be utilized should this prove necessary.

PMID: 17240583 MyJurnal

Eight patients with pituitary tumors were operated via the transseptal transsphenoidal approach from April to November 2004 at Hospital Ipoh. Seven patients presented with visual disturbances while three also had endocrine abnormalities. The post-operative follow-up period was between six months to a year. There was no mortality in this series. There were no complications related to the approach i.e. nasal or septal related. All patients with visual impairment showed improvement. Only one patient had hormonal irregularities. The endoscopic assisted transseptal approach to the sphenoid sinus for pituitary surgery was found to be easy and without sinonasal or labial complications often found with the sublabial approach.

PMID: 17240588

A retrospective review was performed on 11 patients who had undergone the transcolumellar transsphenoidal hypophysectomy in our center. There were eight females and three males with age ranging from 17 to 72 years (mean 50 years). Ten patients had pituitary macroadenomas and one had suprasellar cyst. The mean follow up duration for these 11 patients post surgery was 7.2 months. Complications included two cerebrospinal leaks, one postoperative sphenopalatine bleed, one septal perforation and one patient developed numbness of the tip of the nose. We found that this approach is a preferred alternative technique especially in smaller Oriental noses with lower complication rate and better aesthetic result.

PMID: 17240587

Surgery for pituitary tumours at our institution was performed by rhinosurgical route by combined procedure by otolaryngologist and neurosurgeons. A retrospective review of case records of patients who had endonasal endoscopic transphenoidal approach for pituitary tumours from September 1998 to December 2004 was performed. A total of 81 trans-sphenoidal surgeries were performed during this study period. Only 68 case records with adequate information were available for review, 56 patients were included in the study and 12 were excluded. There were 24 males (42%) and 32 females (58%). The ethnic distribution, were 29 Malays, 24 Chinese, 2 Indian and 1 others. The age ranged from 16 years to 76 years, with a mean of 46 years. The majority of our patients presented with visual symptoms (38), headache (28), menstrual cycle disturbance or impotence (14) and acromegalic features (16). Forty patients had macroadenoma (71%) and 16 had microadenomas (29%). Thirty-six patients out of 40 macro-adenomas had suprasellar extensions (90%). Only eleven patients had lumbar drain inserted prior to commencement of the surgery and the majority of these were macroadenomas. The common complications encountered were diabetes insipidus (4), cerebrospinal fluid leak (2), meningitis (3), epistaxis (2), septal perforation (2), intercavernous sinus haemorrhage (3) and anterior pituitary insufficiency (2). Our study reveals that endonasal trans-sphenoidal approach is a safe and effective method of management of pituitary adenomas.

Singapore Med J, 2007 Jan;48(1):e1-4.

PMID: 17245496

Cerebral angioinvasive aspergillosis is a rare manifestation of disseminated aspergillosis which may result in stroke in immunocompromised individuals. Reports of such disease in patients with diabetes mellitus are rare. We describe a 45-year-old man with diabetes mellitus who presented with a three-day history of right-sided limb weakness and aphasia. Cerebral computed tomography showed features of an acute infarct involving the left anterior and middle cerebral arteries. He was initially treated for an acute ischaemic stroke. Further history revealed that he was investigated for a growth in the sphenoid sinus two months earlier. Culture of the biopsied material from the sphenoid sinus grew Aspergillus fumigatus. Magnetic resonance imaging showed an extension of the growth to the brain, causing the acute ischaemic stroke. He was subsequently diagnosed with angioinvasive cerebral aspergillosis and was commenced on intravenous amphotericin B. Unfortunately, he succumbed to his illness despite treatment.

PMID: 23647078 DOI: 10.3109/02688697.2013.791667

Abstract The endoscopic transnasal, transsphenoidal surgical technique for pituitary tumour excision has generally been regarded as a less invasive technique, ranging from single nostril to dual nostril techniques. We propose a single nostril technique using a modified nasal speculum as a preferred technique. We initially reviewed 25 patients who underwent pituitary tumour excision, via endoscopic transnasal transsphenoidal surgery, using this new modified speculum-guided single nostril technique. The results show shorter operation time with reduced intra- and post-operative nasal soft tissue injuries and complications.

Metastatic hepatocellular carcinoma presenting as a sphenoid sinus mass and meningeal carcinomatosis

Hashim H, Rahmat K, Abdul Aziz YF, Chandran PA

Ear Nose Throat J, 2014 Jun;93(6):E20-3.

PMID: 24932824

We report the case of a 30-year-old woman who was referred to us for evaluation of a 2-week history of fever, headache, vomiting, bilateral ptosis, and blurred vision. Imaging obtained by the referring institution had identified a sphenoid sinus mass and diffuse meningeal infiltration, which was thought to represent an infective process. We subsequently identified the mass as a metastatic hepatocellular carcinoma (HCC). The patient was placed under palliative care, and she died 1 month later. Metastases to the sphenoid sinus from any primary source are very rare, and they are generally not considered in the radiologic differential diagnosis. HCC is known to metastasize to the lung, lymph nodes, and musculoskeletal system; again, reported cases of metastasis to the sphenoid sinus are rare. Indeed, our review of the English-language literature found only 6 previously reported cases of sinonasal metastasis of a primary HCC. A diagnosis of a sinonasal metastasis is more difficult in a patient who has no previous diagnosis of a primary malignancy. In presenting this case, our aim is to remind readers of this possibility.

Iran Red Crescent Med J, 2014 Jul;16(7):e17133.

PMID: 25237579 DOI: 10.5812/ircmj.17133

INTRODUCTION: A mucocele is an epithelial-lined, mucus-containing sac that can fill the sinus completely and expand gradually. Mucopyocele is an infected mucocele.

CASE REPORT: We presented a case of left maxillary mucopyocele in a 58-year-old man that developed after radiotherapy for nasopharyngeal carcinoma. Computed tomography scan showed opacification of the left maxillary sinus expanding through the medial wall of the antrum with thinning and destruction of the adjacent structures. Endoscopic marsupialization of the lesion and left partial maxillectomy were performed. The cystic mass had yellowish thick mucopurulent fluid that was completely drained.

CONCLUSIONS: A few cases of sphenoid sinus mucocele as a late complication of radiation therapy have been reported. Maxillary mucocele and mucopyocele can be considered as one of the late complications of radiotherapy to head and neck as a result of occlusion of sinus ostia by scarred mucosa.

The sphenoid sinus, one of the posterior groups of sinuses, has long been regarded as a 'neglected sinus' due to the anatomical location, poor understanding and poor accessibility, till the advent of endoscopes and modern imaging techniques. Increasing knowledge and greater understanding of this sinus has permitted an evolution in surgical practices and boundaries. Various literatures of the past report a great variety of rates of pneumatization, rates of optic nerve protrusion and dehiscence, as well as internal carotid artery (ICA) protrusion and dehiscence. One similarity noted among these studies is that the rates vary according to the ethnicity of the patients. Recommendations have also been made along the way with regard to modified surgical techniques. This review aims to describe the pneumatization of sphenoid sinus and the topographical relation of the optic nerve and ICA in different populations.

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.

Isolated sphenoid sinus lesions are an uncommon entity and present with non-specific symptoms. In this case report, the patient presented with a history of headaches for a duration of one month without sinonasal symptoms. A computed tomography scan showed a soft tissue mass occupying the sphenoid sinus. An endoscopic biopsy revealed fungal infection. Endoscopic wide sphenoidotomy with excision of the sphenoid sinus lesion was then performed however, the microbiological examination post-surgery did not show any fungal elements. Instead, Citrobacter species was implicated to be the cause of infection.

Cranial encephaloceles are rare conditions, which are more commonly seen in the anterior rather than in the middle cranial fossa. Temporal lobe encephalocele can present with a variety of clinical symptoms, amongst which include occult or symptomatic cerebrospinal fluid (CSF) fistula. We present a case of a patient with a short history of rhinorrhea who was found to have a CSF pool in the sphenoid sinus and right anteromedial temporosphenoidal encephalocele, which mimics sphenoid mucocoele, a much more common entity. This case highlights the imaging findings of temporosphenoidal encephalocoele and the diagnostic clues in differentiating this rare condition from the commoner mimics.
