Hearing Aid Silicone Impression Material Discovered During Exploration of the Middle Ear: 2 Case Reports and Literature Review.

It is unusual to see complications with the preparation of ear mold in order to get hearing aids for children who are in need. However, we came across 2 cases who had a foreign body retained in the middle ear after a long period of time from taking silicon mold impression for hearing aid fitting. One patient presented after 2 years, and the other patient presented after 10 years of hearing aid fitting.

Fusion of Diffusion-Weighted Magnetic Resonance Imaging and High-Resolution Computed Tomography Scan As a Preoperative Tool for Classification of Middle Ear Cholesteatoma.

Background: The role of imaging in cholesteatoma continues to evolve with excellent bony details provided by high-resolution computed tomography and high soft tissue identification for cholesteatoma by diffusion-weighted magnetic resonance imaging. The fusion of highresolution computed tomography and diffusion-weighted magnetic resonance imaging combines the advantages of both imaging techniques.

Methods: A random sample of 40 consecutive patients with chronic suppurative otitis media with cholesteatoma was included in this study.

Value of intraoperative monitoring of the trigeminal nerve in detection of a superiorly displaced facial nerve during surgery for large vestibular schwannomas.

The aim of this study was to investigate the role of trigeminal and facial nerve monitoring in the early identification of a superiorly (anterior and superior (AS)) displaced facial nerve. This prospective study included 24 patients operated for removal of large vestibular schwannomas (VS). The latencies of the electromyographic (EMG) events recorded from the trigeminal and facial nerve innervated muscles after mapping the superior surface of the tumor were analyzed.

Transcanal Endoscopic Management of Glomus Tympanicum: Multicentric Case Series.

Objective: The aim of this study was to report a multicentric surgical experience in the exclusive endoscopic management of glomus tympanicum (GT).

Study Design: Retrospective case series review at two institutions.

Setting: Tertiary referral centers.

COVID-19 and ear endoscopy in otologic practices.

Purpose: Otolaryngologists have had to postpone the majority of surgical procedures in the current COVID-19 pandemic. Airborne transmission, beyond the projection of droplets from upper airways, expose healthcare workers to a risk of viral infection. Aerosol generating procedures (AGP) increase the risk of viral transmission to staff within the operating room.

Petrous apex non-secretory plasma cell myeloma with aberrant cytokeratin expression.

Multiple myeloma is a monoclonal proliferation of plasma cells with common involvement of vertebrae, ribs and skull vault. However, involvement of skull base is relatively uncommon and myeloma manifesting initially as a petrous apex mass is distinctly rare. We report a rare case of non-secretory multiple myeloma in a 52-year-old Egyptian male presenting primarily as a right petrous apex mass with abducens nerve palsy.

Endoscopic Facial Nerve Surgery.

Tympanic facial nerve segment surgery has been traditionally performed using microscopic approaches, but currently, exclusive endoscopic approaches have been performed for traumatic, neoplastic, or inflammatory diseases, specially located at the geniculate ganglion, greater petrosal nerve, and second tract of the facial nerve, until the second genu. The tympanic segment of the facial nerve can be reached and visualized using an exclusive transcanal endoscopic approach, even in poorly accessible regions such as the second genu and geniculate ganglion, avoiding mastoidectomy, bony demolition, and meningeal or cerebral lobe tractions, with low complication rates using a minimally invasive surgical route.

Multichannel facial nerve monitoring: value in detection of mechanically elicited electromyographic activity and prediction of postoperative outcome.

Objective: To determine the value of using a multichannel facial nerve (FN) monitoring setup in detecting mechanically elicited EMG activity during vestibular schwannoma (VS) surgery.

Study Design: Prospective study.

Setting: Tertiary referral center.

Surgery for traumatic facial nerve paralysis: does intraoperative monitoring have a role?

The use of intraoperative facial nerve (FN) monitoring during surgical decompression of the FN is underscored because surgery is indicated when the FN shows more than 90 % axonal degeneration. The present study proposes including intraoperative monitoring to facilitate decision taking and provide prognostication with more accuracy. This prospective study was conducted on ten patients presenting with complete FN paralysis due to temporal bone fracture.

Instrumentation and technologies in endoscopic ear surgery.

This article covers state-of-the-art instruments and devices specially designated for endoscopic ear surgery. New technologies stimulate the creation of special endoscopic equipment and microinstruments specially designed to satisfy the exclusive requirements of endoscopic ear surgery, which contribute to the progress of the procedure. The article presents the advantages and disadvantages of working with ear endoscopes and details the advances in equipment used in ear endoscopies.
