This study analyzed the factors that caused intracranial infection after endoscopic resection of the pituitary tumors by transnasal-sphenoidal approach. A retrospective analysis was performed for 326 patients with resection of pituitary tumor, and multiple Logistic regression analysis was conduced for the relevant factors. Results showed that a total of 32 patients exhibited postoperative infec...

Recent developments have made ultrathin endoscopes available for routine esophagogastroduodenoscopy and also for unsedated transnasal observation (Shaker, 1994). Transnasal endoscopy is known to be less of a burden for patients (more tolerable) than transoral endoscopy and has benefits including fewer effects on respiratory and cardiovascular status and reduced recovery time after the procedure...

Since the introduction of endoscopic technology in the neurosurgical field, the role of transnasal surgery has been dramatically enlarged. With this technique, we can approach the anterior cranial base, parasellar region, clivus, cavernous sinus, and craniovertebral junction, less invasively than with conventional microsurgery. This review describes the two major approach methods in endoscopic ...

UNLABELLED Cerebrospinal fluid (CSF) rhinorrhea is a leakage of fluid from the subarachnoid space to the frontal, sphenoidal or ethmoidal sinuses. CSF rhinorrhea is a known potential complication with significant morbidity and mortality. It may present a significant challenge in diagnosis, localization and management. STUDY DESIGN Series study. MATERIAL AND METHOD Between 1993 and 2004, 44 ...

OBJECTIVE We report the use and benefits of the ultrasonic dissector in the resection of difficult skull base lesions. METHOD Five case reports are presented, and the utilisation of ultrasonic dissectors in otorhinolaryngology is reviewed. RESULTS The ultrasonic dissector was found to be a useful tool during the endoscopic resection of poorly accessible skull base tumours. Safe dissection a...

in this report, we have presented 18fdg-pet findings of organized hematoma of the maxillary sinus (ohms) that showed an increased fdg uptake in the peripheral rim of the mass with central photopenia. to our knowledge, this is the first case report in the literature reporting fdg-pet/ct findings of ohms. careful interpretation of metabolic (fdg-pet/ct) and anatomic (ct and mri) images should be ...

BACKGROUND Nasopharyngeal surgery is commonly performed with a rigid endoscope using a transnasal or transoral approach. Here, we demonstrate a flexible single port computer-assisted endoscopic system enabling easy transoral access to the nasopharynx. METHODS Transoral nasopharyngeal surgery was performed in human cadavers (n = 8) using the Flex System (Medrobotics, Raynham, MA). Learning cur...

BACKGROUND: Odontoidectomy is indicated in the case of anterior compression brainstem structures by an invaginated dentoid process, and it currently possible to perform both transoral microsurgical transnasal endoscopic access.
 OBJECTIVE: To conduct a comparative analysis odontoidectomy performed first author.
 MATERIALS AND METHODS: The treatment results 29 patients with pathologica...
