INTRODUCTION Choanal atresia (CA) is an infrequent congenital obliteration of the airway at the level of the posterior nasal aperture resulting in the absence of connection between the nasal cavity and the aerodigestive tract. We present our experience with an endoscopic technique for congenital CA without the use of intranasal stents. MATERIAL AND METHOD We analysed a series of 10 patients w...

OBJECTIVES The aim of this study was to provide the anatomic rationale for a transnasal approach to the orbital apex and cavernous sinus, and to evaluate its applicability and efficiency. METHODS One hundred patients with lesions of the orbital apex, cavernous sinus, optic nerve, clivus, parapharyngeal space, infratemporal fossa, or pterygopalatine fossa were reviewed over a 10-year period. A...

OBJECTIVE To describe an endoscopic transnasal approach to the pterygopalatine fossa (PPF). DESIGN Case series of 3 patients. SETTING An academic medical center.

Low-grade nasopharyngeal papillary adenocarcinoma is an extremely rare tumor, with only a limited number of cases reported in the literature. Some published studies have paid more attention to the clinicopathological features of nasopharyngeal adenocarcinoma, while little effort has been made to study the optimal therapeutic strategies. We report about a woman diagnosed with low-grade nasophary...

The recent advent of endoscopic procedures has compelled plastic surgeons to reconsider the conventional methods by which the excision of different types of head and neck tumors are classically achieved. Endoscopic resection is a safe and minimally invasive approach and spares unnecessary discomfort to the patient. This article describes the authors' method for performing a video-assisted surge...

Patients usually asymptomatic, diagnosis is established by dental radiographs routine scans. Surgery recommended for dentigerous because ameloblastoma, intraosseous mucoepidermoid carcinoma, or squamous cell carcinoma may develop from them. Generally transoral route pr...
