BACKGROUND Nasal obstruction is a common complaint seen by otolaryngologists. The internal nasal valve (INV) is typically the narrowest portion of the nasal cavity, and if this area collapses on inspiration the patient experiences significant symptoms of nasal obstruction. The nasal obstruction is further compounded if the INV is narrower than normal. Previous studies have evaluated the effecti...

Introduction Given advancements in endoscopic image quality, instrumentation, surgical navigation, skull base closure techniques, and anatomical understanding, the endonasal endoscopic approach has rapidly evolved into a widely utilized technique for removal of sellar and parasellar tumors. Although pituitary adenomas and Rathke cleft cysts constitute the majority of lesions removed via this ro...

A review of endoscopic dacryocystorhinostomy (EDCR) performed in University Hospital from 1998 till early 2001 were carried out. They were reviewed for indication, functional results, complications and other associated factors. Eleven patients (6 female and 5 male) were reviewed. All had unilateral nasolacrimal duct (NLD) obstruction (6 right, 5 left). Their ages range from 6 to 73 years. All 1...

INTRODUCTION We evaluate the ability of a robotic system with needlediameter, tentacle-like manipulators [1] to remove pituitary tumors endonasally. The robot consists of precurved superelastic tubes that can be axially rotated and telescopically extended to create controllable bending and elongation of the manipulator. Pituitary tumors account for 15-20% of all diagnosed primary brain tumors [...

BACKGROUND Surgical scarring on the face and disrupted anatomy in the medial canthal area following external dacryocystorhinostomy (DCR) can be avoided by an endonasal approach. This study examined the outcome of direct visualization endonasal DCR, performed by young surgeons and residents. METHODS A retrospective case series of 75 consecutive endonasal DCRs performed under direct visualizati...

juvenile nasopharyngeal angiofibroma (jna) is a rare, benign and locally invasive tumor. massive bleeding because of vascularity of tumor and postoperative recurrence are potential problems of management. endonasal approach reduces the rate of postoperative recurrence, intraoperative bleeding, and complications of surgery, time of operation and duration of hospitalization. in this article, we r...

background: total and partial gastrectomy is commonly used to treat gastric carcinoma or other benign or malignant conditions of the stomach. laparoscopic-assisted distal gastrectomy is an alternative approach for treating mucosal gastric cancer. many investigators have assessed the safety, efficacy, and feasibility of this procedure.rnobjectives: the aim of present study is to compare the outc...

PURPOSE To compare success rates of external dacryocystorhinostomy (DCR) and endoscopic endonasal DCR for acquired nasolacrimal duct obstruction (NLDO). DESIGN Historical cohort study. PARTICIPANTS 100 patients who underwent external DCR and 105 patients who underwent endoscopic endonasal DCR. METHODS A retrospective review of medical records of patients with acquired NLDO who underwent D...

BACKGROUND Spreader grafts are widely considered to be the mainstay of treatment for insufficient internal nasal valve and are commonly placed preventively during rhinoplasty, after hump removal, to avoid middle vault collapse. Although the placement and suturing of spreader grafts in open rhinoplasty is fairly easy, their positioning and stabilization in endonasal rhinoplasty is associated wit...
