Endoscopic ear surgery (EES) is increasingly a preferred technique in otologic society. It offers excellent visualization of the anatomical structures directly and behind the corners with variable angled telescopes. It also provides reduced operative morbidity due to being able to perform surgical interventions with less invasive approaches. Operative preparation and setup time and cost of endoscopy system are less expensive compared with surgical microscopes. On the other hand, the main disadvantage of EES is that the surgery has to be performed with 1 single hand...

For neurosurgeons, who are accustomed to the binocular microscope, there is a new learning curve that must be overcome for monocular endoscopic pituitary surgery. Different studies describe a learning curve between 15 and 200 procedures, after which both operative time and complications stabilize. In this retrospective study, we evaluate the endoscopic learning curve of our group, already trained in microsurgical transsphenoidal surgery, with the assistance of ear, nose, and throat (ENT) surgeons. From 2010 to 2015, a total of 95 patients with pituitary adenomas were treated with a purely endoscopic approach...

Objective Transcanal exclusive endoscopic ear surgery requires the management of the endoscope and the surgical instruments in the external auditory canal. Bleeding in this narrow space is one of the most challenging issues, especially for novice endoscopic ear surgeons. We aim to assess the severity and occurrence of bleeding and describe strategies to control the bleeding during endoscopic ear surgery. We hypothesize that bleeding is reasonably controllable in endoscopic ear surgery. Study Design Case series with chart review...

This article analyzes the role played by the ear, nose and throat (ENT) specialist in the diagnosis and treatment of the Obstructive Sleep Apnea Syndrome (OSAS). DIAGNOSIS: The instrumental methods of investigation of otolaryngology expertise are fiberoptic rhinolaryngoscopy and sleep endoscopy. To better define and treat OSAS it is essential to define location, extension and degree of obstruction. The major limitation of rhinolaryngoscopy is that it is conducted while the patient is awake...

BACKGROUND: Chronic rhinosinusitis (CRS) is a downstream complication following radiotherapy or chemoradiation for nasopharyngeal carcinoma (NPC). Endoscopic sinus surgery (ESS) is an accepted therapy for medically refractory CRS, but its efficacy in addressing CRS symptoms in patients with previously irradiated NPC is unclear. METHODS: All patients at the Stanford Sinus Center with a history of radiation therapy or chemoradiation for NPC between 2006 and 2015 were reviewed...

OBJECTIVES/HYPOTHESIS: To design and validate a classification system for endoscopic ear surgery. STUDY DESIGN: Validation study. METHODS: A classification system was devised that quantifies use of the endoscope during middle ear surgery. Otologic operative reports were reviewed by attending surgeons and trainees. A power analysis was performed to determine number of cases needed to review. The following categories were used: class 0 is defined by using the microscope only; class 1 describes the use of endoscope for inspection without dissection; and class 2 describes mixed use of the endoscope and the microscope...

The goal of this work is to develop an innovative method that combines bioprinting and endoscopic imaging to repair tympanic membrane perforations (TMPs). TMPs are a serious health issue because they can lead to both conductive hearing loss and repeated otitis media. TMPs occur in 3-5% of cases after ear tube placement, as well as in cases of acute otitis media (the second most common infection in pediatrics), chronic otitis media with or without cholesteatoma, or as a result of barotrauma to the ear. About 55,000 tympanoplasties, the surgery performed to reconstruct TMPs, are performed every year, and the commonly used cartilage grafting technique has a success rate between 43% and 100%...

PURPOSE: There are no formal radiologic criteria to stratify patients for transcanal (TEES) or transmastoid endoscopic ear surgery for resection of cholesteatoma. We aim to determine 1) whether standard preoperative computed tomography (CT) findings are associated with the need for conversion to a transmastoid approach and 2) the amount of time added for conversion from TEES to transmastoid techniques. MATERIALS AND METHODS: Retrospective chart review of consecutive pediatric and adult cases of TEES for primary cholesteatoma from 2013 through 2015 (n=52)...
