Frontal Sinus Surgery Anterior to the Ethmoid Bulla

Extended endoscopic frontal sinus surgery to interrupted nasofrontal communication caused by scarring of the anterior ethmoid: long-term results.

OBJECTIVE To examine the long-term results of extended endoscopic frontal sinus surgery, including removal of the floor of the frontal sinus (Draf type II procedure) and the median drainage operation (Draf type III procedure or modified Lothrop procedure), for obstructive frontal sinusitis caused by postoperative scar formation, with the emphasis on the long-term success of the median drainage ...

Frontal sinus septations predict the presence of supraorbital ethmoid cells.

OBJECTIVES/HYPOTHESIS This study is undertaken to determine if the presence or absence of multiseptated frontal sinuses is associated with the presence or absence of supraorbital ethmoid cells (SOECs). STUDY DESIGN Analysis of prospectively collected data. METHODS Sixty consecutive patients with chronic rhinosinusitis were identified from a prospectively collected database at a tertiary-ref...

Study of Anthropometric Measurements of the Anterior Ethmoidal Artery using Three-dimensional Scanning on 300 Patients

Introduction The anterior ethmoidal artery (AEA) is one of the main arteries that supply both the nasal mucosa and the ethmoid sinuses. The AEA shows variability regarding its distance from adjacent structures. Several studies have developed techniques to identify the AEA. Objective This study aimed to compare the measurements from the AEA to the ethmoid bulla and to the frontal beak by using c...

combined aplasia of sphenoid, frontal, and maxillary sinuses with hypoplasia of the ethmoid sinus

Sudden Hemianopsia Secondary to Ethmoid Sinus Mucocele

Paranasal sinus mucoceles are benign cystic lesions, filled with mucus, occurring due to an obstruction of involved sinus ostium. They are indolent, locally expansive, and destructive. Surgical treatment must be performed and, when done at the correct time, may prevent sequelae. We present a case of ethmoid sinus mucocele with orbit involvement and permanent optical nerve injury.
