Sphenoid sinus mucocele is a rare condition. In this study, radiation to the head and neck appeared to be a predisposing factor, and eye symptoms were the commonest presentation. Endoscopic sinus surgery is a safe and effective treatment modality.
Sinonasal inverted papillomas are well known for high recurrence rates after surgery and the risk of malignant change. Recurrent disease occurs because of inadequate excision as a result of poor exposure and visualization. For these reasons, aggressive surgery has been advocated-classically a lateral rhinotomy and en bloc medial maxillectomy. Endoscopic techniques have provided excellent visualization and a less invasive approach to these tumours. We describe 18 patients with inverted papillomas treated endoscopically at the Singapore General Hospital since 1993. The presentation, sites of involvement and diagnostic imaging are presented. All the patients had a minimum follow-up of 18 months with a mean of 32.8 months. One case of recurrence at the frontal recess is reported. Endoscopic management is appropriate for the diagnosis, follow-up and treatment of circumscribed primary and recurrent inverted papillomas.
Excision of the submandibular gland is a surgical procedure often undertaken. The procedure is the treatment of choice for patients with neoplasm of the submandibular gland and those with non-neoplastic submandibular disorders which are not controlled with conservative medical measures. Extirpation of the submandibular gland may also be undertaken for diagnostic purposes.This retrospective study of 93 consecutive patients who underwent excision of the submandibular gland in the Department of Otolaryngology, Singapore General Hospital over a five-year period was undertaken to study the indications of surgery, the pathology of the excised submandibular gland and the demographic profile of patients.Fifty-six (60.2 per cent) patients underwent submandibular gland excision for non-neoplastic salivary gland disease while 37 (39.8 per cent) had neoplastic submandibular gland disorders. The commonest pathology encountered was sialadenitis/sialolithiasis (53.76 per cent) followed by pleomorphic adenoma (33.33 per cent). Fine needle aspiration cytology (FNAC) was a valuable pre-operative investigation with a sensitivity and specificity of 94.7 per cent and 100 per cent respectively for neoplastic diseases. The morbidity rate for this surgery was 4.3 per cent.
This paper presents a review of the various diseases of the sphenoid sinus and describes the approaches to the sinus with special emphasis on the transpterygoid approach to the lateral recess of the sphenoid sinus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
