Background: Nose is used as a corridor in endoscopic endonasal transsphenoidal approach (EETSA) for pituitary adenoma. Thus, it may affect the nasal airway patency, function and sinonasal-related quality of life. The aim of this study is to objectively and subjectively evaluate these effects.   Methods: In this prospective study, 43 patients with pituitary adenoma who were c...

OBJECTIVE/HYPOTHESIS The role of endoscopic sinus surgery for treating chronic maxillary sinusitis is well established. The purpose of the study is to determine the efficacy of endoscopic sinus surgery in the treatment of maxillary sinus inflammatory disease that includes mucoceles, retention cysts, and antrochoanal polyps. STUDY DESIGN This is a retrospective review of 32 consecutive patient...

In endoscopic neurosurgery problems with haemostasis due to poor access exist. We have developed a system which allows the delivery of a variety of haemostatic agents in a more efficacious manner. The system has been used successfully in endoscopic skull base surgery and endoscopic surgery within the parenchyma of the brain using tube systems.

OBJECTIVE There is currently no standardised management protocol following functional endoscopic sinus surgery. This study assessed frequent endoscopic cleaning versus minimal intervention in the early post-operative period following such surgery. STUDY DESIGN Prospective, randomised controlled, single-blinded, within-subject trial involving 24 patients with bilateral chronic rhinosinusitis u...

OBJECTIVE We assessed the optimal time interval between endoscopic stenting and subsequent surgery in patients with obstructive left-sided colon cancer. METHODS We reviewed the medical records of patients who underwent endoscopic colonic stenting for obstructive left-sided colon cancer between January 2009 and January 2012. Patients who had successful endoscopic intervention as a bridge to su...

Endoscopic endonasal surgery has become a standard procedure for functional treatment of benign pathologies. Materials and improved surgeon skills have allowed the number of indications for this approach to increase. We describe some of the main pathologies, including malignancies, that can be treated endoscopically, focussing on the orbital and skull base pathologies. The orbital indications d...

A new paradigm in the treatment of obesity and metabolic disease is developing. The global obesity epidemic continues to expand despite the availability of diet and lifestyle counseling, pharmacologic therapy, and weight loss surgery. Endoscopic procedures have the potential to bridge the gap between medical therapy and surgery. Current primary endoscopic bariatric therapies can be classified a...

OBJECTIVE To determine whether the 15-degree reverse Trendelenburg position (RTP) during functional endoscopic sinus surgery improves endoscopic field of view and reduces intraoperative blood loss when compared with the horizontal position (HP). STUDY DESIGN A prospective, randomized controlled trial. SETTING St Paul's Sinus Centre, Vancouver, Canada. SUBJECTS Patients with chronic rhinos...

Traditional surgery for cholesteatoma of the middle ear is performed by microscopic approaches. However, in recent years endoscopic instrumentation, techniques and knowledge have greatly improved, and in our opinion endoscopic surgical techniques will gain increasing importance in otologic surgery in the future. The aim of this study was to focus on outcomes obtained using endoscopic surgery fo...
