The minimal access retrosigmoid endoscopic approach to vestibular schwannoma (VS) resection has been used with promising results. However, it has not been compared with the standard open approach in the literature. We performed a meta-analysis review for all articles describing both approaches for VS from 1996 to 2011. We found 1861 articles. After review and discussion, we narrowed our study t...

This prospective longitudinal study was done to determine extent of tumor and to highlight the importance of lateral rhinotomy approach for nasopharyngeal angiofibroma. Patients with a diagnosis of nasopharyngeal angiofibroma who underwent surgery in Tribhuvan University Teaching Hospital, Maharajgunj, Kathmandu from April, 2004 to Jan 2009 were included in the study. Extent of tumour and surgi...

Nasoalveolar cysts, which originate from epithelial remnants of nasolacrimal duct, are nonodontogenic soft tissue lesions of the upper jaw. These cysts are thought to be developmental and are presented with fullness in the upper lip and nose, swelling on the palate, and sometimes nasal obstruction. Because of cosmetic problems, they are often diagnosed at an early stage. These lesions are mostl...

UNLABELLED The productive work between otolaryngologists and neurosurgeons has resulted in the emergence of endoscopic endonasal skull base surgery. The goal of the present study is to describe the endoscopic anatomy of the endonasal approach to the sellar region and planum sphenoidale, highlighting the key points of the surgical approach and the neurovascular landmarks. METHOD Descriptive st...

OBJECTIVES/HYPOTHESIS To evaluate the cost-effectiveness of an endoscopic versus microscopic approach to pituitary adenoma resection. STUDY DESIGN Markov decision tree economic evaluation. METHODS An economic evaluation using a Markov decision tree model was performed. The economic perspective was that of the healthcare third-party payer. Effectiveness and probability data were obtained fro...

We reported two patients with nasopharyngeal adenocarcinoma resected by using the exclusively endoscopic approach. Case reports and a review of the world literature concerning nasopharyngeal adenocarcinoma. The tumors were resected successfully via the exclusively endoscopic approach and no conversions to the conventional approach were necessary. The two patients were followed up for 26 and 18 ...

Recently, the endonasal transsphenoidal approach has been widely used as the standard technique for pituitary surgery instead of the sublabial approach. However, using this approach involves potential conflicts between surgical instruments when entering the nostril and while working inside even with an endoscope. In patients with small nostril, it requires an additional tension release incision...
