Giant Sphenochoanal Polyp - A Case Series

Abstract

Introduction : Chronic rhinosinusitis with polyposis is a common condition occurring world wide . polyps arising from unusual regions of the nasal cavity and paranasal sinuses are quite rare. One such uncommon entity is the sphenochoanal polyp.  There is very less literature on the occurrence of sphenochoanal polyps world wide.^1,4,5  It was most commonly seen in children and young adults.

Case series :  We present three of our cases with isolated sphenoid sinusitis with polyps hanging in to the nasopharynx.  These patients were managed surgically by functional endoscopic sinus surgery and removal of polyp under GA . They were all given a course of oral steroids under antibiotic cover post operatively.

Conclusion : Although sphenochoanal polyps have been described about in literature they are less common from those occurring from the other paranasal sinuses. A slim probability of immotile cilia syndromes should be kept in mind in case where there are recurrences. A unilateral nasal mass arising from the posterior part of roof of nasal cavity should rise suspicion of malignancy, rathkes cleft cyst and meningoenchephalocoels. Drainage of the middle meatus is crucial in preventing iatrogenic complications.
