Dysphagia due to tumor ulcers and stomatitis induced by chemoradiotherapy is painful; it is therefore crucial and urgent to establish a surgical enteral feeding route in patients with head and neck cancer to avoid malnutrition and improve treatment compliance [1]. However, common trismus caused by surgical resection, reconstruction, and, mostly, radiation fibrosis often compromise flexible endo...

The course of patients with advanced ovarian carcinoma is often complicated by bowel obstruction and/or massive ascites. A transnasal long tube may be placed to relieve bowel obstruction, but produces nasal discomfort and pain. Recently, the effectiveness of percutaneous endoscopic gastrostomy (PEG) tube placement for malignant bowel obstruction due to ovarian carcinoma has been reported, but n...

Background Cholesterol granulomas arising at the petrous apex can be treated via traditional open surgical, endoscopic, and endoscopic-assisted approaches. Endoscopic approaches require access to the sphenoid sinus, which is technically challenging in patients with conchal sphenoidal anatomy. Clinical Presentation A 55-year-old woman presented with intermittent headaches and tinnitus. Formal au...

Review of the literature was performed to define the optimal treatment of patients with juvenile nasopharyngeal angiofibroma (JNA). The prognosis for this disease is extremely good if diagnosed well in time and if the tumor has not extended intracranially. Preoperative selective arterial embolization has decreased intraoperative blood loss and facilitated resection of larger tumors. Transnasal ...

Objective Although posterior epistaxis is rarely seen, it is an important medical problem that both decreases the quality of life of the patient and causes difficulties in the management for otorhinolaryngologists. In this study, we aimed to present the results of 30 patients who underwent transnasal endoscopic sphenopalatine artery ligation (TESPAL) for posterior epistaxis in our department. ...

INTRODUCTION The large increase in the number of transnasal endoscopic skull base surgeries is a consequence of greater knowledge of the anatomic region, the development of specific materials and instruments, and especially the use of the nasoseptal flap as a barrier between the sinus tract (contaminated cavity) and the subarachnoid space (sterile area), reducing the high risk of contamination....

INTRODUCTION Nasopharyngectomy has been established as a feasible curative treatment for salvaging recurrent nasopharyngeal carcinoma after radical radiotherapy. A large case series has also shown that the overall survival rate in nasopharyngectomy is comparable with reirradiation in small recurrent tumors. However, reirradiation has significant late complications from radiotherapy, and surgica...

Objectives Our laboratory is developing a surgical robotic system to further improve dexterity and visualization that will allow for broader application of transnasal skull base surgery. To optimize this system, intraoperative force data are required. Using a modified curette, force data were recorded and analyzed during pituitary tumor excision. Design A neurosurgical curette was modified by t...

background: proposing a strategy for sellar reconstruction in endoscopic transsphenoidal transsellar approach for pituitary adenoma. methods: 240 patients with pituitary adenoma underwent pure endoscopic endonasal transsphenoidal surgery. intra-operative csf leaks were classified as grade 0, no observable leak grade 1, csf dripping through an arachnoid membrane defect of less than 1 mm and grad...

introduction: endoscopic sinus surgery is a common procedure performed by otolaryngologists. this study evaluated the efficacy of intravenous (iv) tranexamic acid (ta) on hemorrhage  in patients undergoing elective endoscopic sinus surgery (ess).   materials and methods: the present study was performed in 170 patients scheduled for ess surgery under general anesthesia in order to examine the ef...
