Endoscopic approaches to benign sphenoid sinus lesions: development of an algorithm based on 13 years of experience.

Objective: To develop an algorithm for selecting the optimal endoscopic approach for benign sphenoid lesions.

Methods: Charts of 392 patients were reviewed and categorised according to disease nature and extent as follows: group 1 comprised isolated sphenoid sinus lesion cases, group 2 consisted of pansinus lesion cases and group 3 comprised lateral sphenoid recess lesion cases. Surgical approaches, difficulties and complications were noted.

A 13-year experience and predictors for success in transnasal endoscopic repair of congenital choanal obliteration.

Objective: To express a 13-year experience in transnasal endoscopic repair of congenital choanal obliteration and to analyze the different predictors that may affect the surgical outcome.

Design: Retrospective clinical study.

Setting: Otolaryngology Department, Tanta University Hospital, Egypt.
