INTRODUCTION Dacryocystorhinostomy (DCR) is the treatment of choice for nasolacrimal duct obstruction. Although external DCR is regarded as the gold standard, endoscopic DCR is evolving as an equally-effective alternative. Objectives To compare the success rate of treating nasolacrimal duct obstruction by endoscopic endonasal method compared to the conventional DCR surgery. Materials and method...

Ossifying fibroma is a benign fibro-osseous tumour that rarely involves the ethmoid sinuses and orbit. It is classified as a benign fibroosseous lesion, a term that is synonymous with a variety of lesions reported in the literature. Recurrence rate with deleterious effects in cases of extramandibular ossifying fibroma is the impetus for open en bloc resection of the tumour. Continuously evolvin...

Since the introduction of endonasal endoscopic skull base surgery the exclusive purpose in the management of skull base neoplasms has been to increase survival rates. Recently, given the improved prognosis achieved, more attention has been focused on the functional outcomes such as nasal symptoms and quality of life (QOL). The purpose of this review is to assess the functional outcomes after en...

OBJECTIVE To study anatomical structures related to Meckel cave with endonasal endoscopic approach and to provide an anatomical basis for endoscopic surgery in Meckel cave. METHODS Meckel cave of 5 adult skulls (10 sides) were fixed with 10% formalin. The anatomical structures of Meckel cave and the related zones adjacent to Meckel cave were observed and measured with endoscopic endonasal app...

OBJECTIVE Analyse technical aspects, effectiveness and morbidity of the endoscopic endonasal transphenoidal approach for pituitary adenomas. METHOD From January 2005 to September 2008, 30 consecutive patients underwent endoscopic endonasal resection of pituitary adenomas with a follow up from 3 to 36 months. Their medical charts were retrospectively analysed. RESULTS There were 18 women and...

Anterior cerebral artery (ACA) encasement is often considered a contraindication for an endonasal endoscopic transsphenoidal approach. We report a patient with a tuberculum sella meningioma with ACA encasement, in whom a gross total excision was achieved through an endonasal endoscopic transsphenoidal transtuberculum, transplanum approach. The tumor was sharply dissected along the left ACA usin...

An 89-year-old male presented with cerebrospinal fluid (CSF) rhinorrhea associated with head trauma sustained as a pedestrian in a traffic accident. Computed tomography (CT) showed pneumocephalus and multiple cranial bone fractures, including the clivus. Although the CSF rhinorrhea was treated conservatively for a week, clinical symptoms did not improve and surgical repair was performed. Preope...

The aim of this report was to summarize our preliminary experience on the resection of tumors located in Meckel's cave via the endoscopic endonasal transmaxillary transpterygoid approach with image-guided system and to investigate the feasibility and efficacy of this approach. Two patients who had tumors in left Meckel's cave underwent surgical treatment using the image-guided endoscopic endona...

OBJECTIVES Endonasal dacryocystorhinostomy (DCR) is a well-established treatment method in patients with nasolacrimal duct obstruction. However, there are a few reports about the overall management of failed endonasal DCR. We investigated the causes and management strategies of failed endonasal DCR. METHODS This retrospective review included 61 patients (61 eyes) who had undergone revision su...

We evaluated the efficacy of interpositional auricular cartilage grafting for perforation with an endoscopic endonasal approach via a mucosal regeneration technique. In total, 12 patients with symptomatic septal perforations were operated on by way of an endoscopic endonasal approach after an adequately sized cartilage graft was harvested. The graft was inserted between the circumferentially in...
