[Diagnosis and therapy of choanal polyps from posterior ethmoid sinus].
OBJECTIVE
To investigate the clinical feature, diagnosis and endoscopic surgery of choanal polyps (CP) from posterior ethmoid sinus.


METHODS
Eleven cases with CP from posterior ethmoid sinus treated by endoscopic endonasal surgery between January 2002 to June 2007 were retrospectively reviewed. Clinical manifestation, intranasal and intrasinus lesions, methods and attentions of endoscopic surgery and therapeutic effects were analysed.


RESULTS
All cases were treated by endoscopic surgery and CP were found originated from posterior ethmoidal ostium. Lesions in posterior ethmoid sinus included 3 (27.3%) cyst, 5 (45.4%) polyp and 3 (27.3%) mucosal edema. No operation complications were observed. The follow-up period ranged from 6 months to 3 years (mean 1.2 years) and no recurrence was founded.


CONCLUSIONS
Most of CP originated from posterior ethmoidal ostium and its formation might be related to the cyst in the sinus. Endoscopic surgery represents a minimally invasive and highly successful procedure, complete removal of CP and lesions in the sinus can reduce the recurrence.
