Sphenochoanal polyp - Surgical review

A sphenochoanal polyp is a rare lesion that originates in the sphenoid sinus and protrudes through the choana into the nasopharynx. It can occur at any age but is especially common in adolescents and young adults. We present a case of a sphenochoanal polyp in a seven-year-old girl who presented with bilateral nasal obstruction and an altered voice. The presentation of a sphenochoanal polyp is similar to that of the more common antrochoanal polyp, but the two can only be differentiated on cross-sectional imaging (computed tomography and/or magnetic resonance imaging). Endoscopic sinus surgery allows for complete removal and minimizes the risk of recurrence.
