title: [A new variant of choanal polyps].
abstract: Seven cases of ethmochoanal polyps, a form of nasal polyps, originating from mucosa of the back ethmoidal labyrinth and lowering into the nasopharynx are described. Such polyps are diagnosed primarily by computed tomography and endoscopy of the nasal cavity. Histologically, ethmochoanal polyps are similar to other polyps from paranasal sinuses. Surgical treatment of ethmochoanal polyps is made under the control of endoscope via approach through the superior nasal passage. The polyp part situated in posterior compartment of the ethmoidal labyrinth was removed with a microdebrider. 1 to 3 year follow-up registered no cases of recurrence.
