Two Cases of Isolated Frontal Septal Cell Inflammation Treated with the Draf IIb Procedure

Abstract

The frontal septal cell (FSC) is a medially based air cavity of the anterior ethmoid or the inferior frontal sinus, located in the interfrontal sinus septum. FSC pathologies are extremely rare although they are common frontal recess cells. We report on two patients with isolated FSC sinusitis presenting with frontal headache who were treated with Draf IIb endoscopic sinus surgery (ESS). Paranasal sinus computed tomography of the patients revealed a clear frontal sinus and FSC soft tissue density. The patients underwent a Draf IIb procedure through left-sided approach to treat FSC inflammation. After surgery, the patients no longer complained of headache, and the widened outflow tract was maintained without narrowing in endoscopic views during 2 years of followup. When a patient presents with continuous frontal headache, FSC inflammation should be considered. It can be successfully treated by Draf IIb ESS
