The Agger Nasi Punch-Out Procedure (POP): maximizing exposure of the frontal recess.

摘要: INTRODUCTION For many patients with chronic frontal sinusitis, removal of the uncinate process and limited opening anterior ethmoid air cells is adequate to restore proper sinus drainage ventilation. those more advanced disease, however, surgery enlarge outflow tract may be required. Typically, recess enlarged in anteroposterior dimension through clearance agger nasi cells. The ostium then identified even if necessary. Surgery can technically challenging because variability its anatomy as well location within anterosuperior depths nasal cavity. proximity orbit intracranial cavity demands precision when operating this region. Therefore, exposure critical performance safe effective surgery. We describe a simple technique enhance thereby facilitate identification enlargement ostium.
