Introduction:
Sphenochoanal polyps (SCP) grow from the sphenoid sinus and occupy the nasopharynx.
Objective And Results:
To describe the clinical and diagnostic features of SCP, reporting two cases. Epidemiological study of the series in the literature. 8 published series were found (22 cases).
Conclusions:
SCP is a rare lesion that is usually misdiagnosed for antrochoanal polyposis. A proper diagnosis and surgical treatment are the basis to prevent recurrence. We describe the first case of SCP with cacosmia.
