UNLABELLED The frontal sinus trauma is not rare and it is 8% of the facial fractures. It can affect the anterior and/or posterior plates, with or without hitting the nasofrontal duct. It has a large potential of complications and its management still being a controversy. OBJECTIVE To present the casuistic of fractures frontal sinus, the epidemiology and clinical and surgical management of fro...

INTRODUCTION Computer-aided surgery (CAS) systems integrate endoscopic visualization with real-time localization based on preoperative imaging. One short-coming of the current systems is the lack of real-time, radiographic assessment of surgical changes. We describe the potential applications of xCAT, a new intraoperative mobile volume CT scanner and its utility in providing surgical navigation...

OBJECTIVE Radiographic frontal recess and sinus anatomic measurements were obtained to evaluate the feasibility of the endoscopic modified Lothrop procedure. STUDY DESIGN Computed tomography anatomic study. MATERIALS AND METHODS Computed tomography (CT) scans from 97 patients, 39 male and 58 female, were analyzed in the sagittal plane. Four anatomic parameters were measured 1) midsagittal t...

INTRODUCTION AND AIMS The frontal sinus ostium is frequently difficult to recognize because of anatomical structures that hide it. The objective of the present study was to identify and describe the frontal recess anatomy that impairs the endoscopic recognition of the frontal sinus ostium. STUDY DESIGN AND METHODS A prospective study was conducted by consecutive endoscopic dissections of 32 c...

INTRODUCTION Surgical management of the frontal sinus is more complex compared to the other sinuses. Testament to this fact is that for years the standard for refractory frontal disease has been the destructive procedure of an osteoplastic flap with complete obliteration of the sinus. With better understanding of the physiology of the paranasal sinuses, there has been a shift toward surgery dir...
