OBJECTIVES/HYPOTHESIS Extirpation via expanded endonasal approaches (EEA) to the skull base can result in defects requiring vascularized rotational flap reconstruction. The buccal fat pad (BFP) is a vascularized graft described in open skull base resections, but its harvest and adequacy of vascular supply have not been examined for use with EEA. STUDY DESIGN A transfacial cadaveric dissection...
Neurofibromatosis type I (NF1) is a neurocutaneous disorder that involves autosomal dominant transmission. Skull defects, including sphenoid dysplasia and calvarial defects, are a rare finding in patients with NF1. Spinal meningocele and sphenoid wing dysplasia have been identified in NF1 but the occurrence of meningoceles at the skull base is extremely rare. A rare instance of jugular foramen ...
Surgery of the ear and the lateral skull base is a fascinating, yet challenging field in otorhinolaryngology. A thorough knowledge of the associated complications and pitfalls is indispensable for the surgeon, not only to provide the best possible care to his patients, but also to further improve his surgical skills. Following a summary about general aspects in pre-, intra-and postoperative car...
abstract background: invasive fungal infection is an opportunistic infection caused commonly by mucoraccae and aspergillus. it mostly occurs in patients with underlying disease. since it has a high mortality and morbidity rate, considering a treatment strategy seems necessary. objective: since there has not been a clear protocol for treating these patients, we decided to establish a protocol ...
A 65-year-old male presented with a 3-year history of orbital symptoms. An imaging-based diagnosis of fibrous dysplasia involving the skull base was made at another institution. CT showed a diffuse sinonasal mass and ground-glass appearance of the bones of the anterior skull base with bony defects and mucocele formation. MRI demonstrated an accompanying intracranial and orbital rind of soft tis...
BACKGROUND Osteoradionecrosis (ORN) is a challenging complication in patients with postirradiated nasopharyngeal carcinoma (NPC). The aim of this study was to evaluate the usage of a nasoseptal flap (NSF) after endoscopic sequestrectomy to reconstruct resultant skull base defects for the treatment of ORN. CASE PRESENTATION We present our experience on the adaption of an NSF as a reconstructio...
