abstract   background: over the past 20 years, the minimally invasive endoscopic approach has gained widespread acceptance. the study was performed to evaluate the diagnostic method and the success rate of endoscopically diagnosed and treated csf rhinorrhea, and also investigations such as leakage site and etiologic factor.   methods: this retrospective csf leakage management review of patients...

Introduction A substantial body of literature has been devoted to the distinct characteristics and surgical options to repair the skull base. However, the skull base is an anatomically challenging location that requires a three-dimensional reconstruction approach. Furthermore, advances in endoscopic skull base surgery encompass a wide range of surgical pathology, from benign tumors to sinonasal...

OBJECTIVES/HYPOTHESIS Endoscopic endonasal skull base surgery defects require effective reconstruction. Although the nasoseptal flap (NSF) has become our institution's workhorse for large skull base defects with cerebrospinal fluid (CSF) leaks, situations where it is unavailable require secondary flaps. Clinical outcomes, pearls and pitfalls, and an algorithm will be presented for these seconda...

INTRODUCTION Endoscopic techniques have been used extensively for the treatment of sinonasal skull base defects and resulting cerebrospinal fluid (CSF) leaks. Endoscopic surgery allows for improved visualization, high success rates, reduced morbidity, and shorter hospital stays. Most ethmoid and sphenoid skull base defects can be repaired endoscopically, but endoscopic repair of frontal sinus d...

Skull base surgical defects present unique challenges to anatomic and functional reconstruction. Fortunately, many endonasal skull base defects are successfully managed with a variety of local and regional reconstructive techniques. However, when prior surgery or radiotherapy eliminates the use of these local and regional reconstructive options, more elaborate free tissue transfer techniques ar...

Background: The last decades have witnessed remarkable progress in the field of endoscopic skull base surgery. The nose has become an established route for addressing different skull base lesions. The reconstruction after resection is a critical step for optimum surgical outcome. Objective: Evaluation of the difference in the clinical outcomes between the use of vascularized flaps and free graf...

Endonasal skull base surgery is growing exponentially as a subspecialty. In recent years, advances in endoscopic techniques and intraoperative navigation systems have allowed us to expand the indications of endoscopic skull base surgery. Major skull base centers worldwide are addressing larger and more complex lesions using endoscopic techniques. As a consequence, the skull base defects are mor...

Objectives. To compare reconstructive techniques, operative times, duration of hospitalization, and need for subsequent flap revisions between reconstructive approaches to lateral skull base defects. Study Design. Case series with chart review. Setting. Tertiary academic referral center. Subjects. Patients (n = 31) undergoing reconstruction of composite lateral skull base defects from 2002 to 2...

INTRODUCTION We present our experience in the reconstruction of these leaks depending on their size and location. MATERIAL AND METHODS Fifty-four patients who underwent advanced skull base surgery (large defects, >20 mm) and 62 patients with CSF leaks of different origin (small, 2-10 mm, and midsize, 11-20 mm, defects) were included in the retrospective study. Large defects were reconstructed...
