Treatment and Prognosis of Facial Palsy on Ramsay Hunt Syndrome: Results Based on a Review of the Literature.

 Ramsay Hunt syndrome is the second most common cause of facial palsy. Early and correct treatment should be performed to avoid complications, such as permanent facial nerve dysfunction.  The objective of this study is to review the prognosis of the facial palsy on Ramsay Hunt syndrome, considering the different treatments proposed in the literature.

Decompression of the tympanic and labyrinthine segments of the facial nerve by middle cranial fossa approach: an anatomic study.

Background: Peripheral facial palsy is characterized by the permanent or temporary interruption of facial muscle function. The middle cranial fossa (MCF) approach has been used to decompress the facial nerve (FN) when hearing needs to be preserved. In this work, we describe a technique for decompressing the FN through the MCF approach, which allows the direct exposure of the labyrinthine and entire tympanic segment of the FN, with preservation of inner ear function.

Intracochlear schwannoma: diagnosis and management.

Introduction Schwannomas of the eighth cranial nerve are benign tumors that usually occur in the internal auditory canal or the cerebellopontine angle cistern. Rarely, these tumors may originate from the neural elements within the vestibule, cochlea, or semicircular canals and are called intralabyrinthine schwannomas. Intracochlear schwannomas (ICSs) represent a small percentage of these tumors, and their diagnosis is based on high-resolution magnetic resonance imaging (MRI).

Implantable and semi-implantable hearing AIDS: a review of history, indications, and surgery.

Introduction The complaints associated with the use of conventional amplifying hearing aids prompted research at several centers worldwide that ultimately led to the development of implantable devices for aural rehabilitation. Objectives To review the history, indications, and surgical aspects of the implantable middle ear hearing devices. Data Synthesis Implantable hearing aids, such as the Vibrant Soundbridge system (Med-El Corporation, Innsbruck, Austria), the Maxum system (Ototronix LLC, Houston, Texas, United States), the fourth-generation of Carina prosthesis (Otologics LLC, Boulder, Colorado, United States), and the Esteem device (Envoy Medical Corporation - Minnesota, United States), have their own peculiarities on candidacy and surgical procedure.

Remote programming of cochlear implants.

Purpose: To verify the effectiveness of remote programming of cochlear implants by stimulation levels and results in the perception of speech and free-field audiometry tests.

Methods: Twelve patients from both genders, aged between 18 and 59 years, users of internal cochlear implant and speech processor of the same model for at least 12 months, were selected. Both the remote programming (RP) and the live programming (LP) were performed on the same day, measuring the minimum (T) and maximum (C) stimulation levels of five electrodes with the interpolation of the remaining ones.

Carina® and Esteem®: a systematic review of fully implantable hearing devices.

Objective: To review the outcomes of the fully implantable middle ear devices Carina and Esteem regarding the treatment of hearing loss.

Data Sources: PubMed, Embase, Scielo, and Cochrane Library databases were searched.

Study Selection: Abstracts of 77 citations were screened, and 43 articles were selected for full review.

Retrolabyrinthine approach for cochlear nerve preservation in neurofibromatosis type 2 and simultaneous cochlear implantation.

Introduction:  Few cases of cochlear implantation (CI) in neurofibromatosis type 2 (NF2) patients had been reported in the literature. The approaches described were translabyrinthine, retrosigmoid or middle cranial fossa.

Objectives:  To describe a case of a NF2- deafened-patient who underwent to vestibular schwannoma resection via RLA with cochlear nerve preservation and CI through the round window, at the same surgical time.

Middle ear adenoma with neuroendocrine differentiation: relate of two cases and literature review.

Introduction:  Adenomas with neuroendocrine differentiation are defined as neuroendocrine neoplasms, and they are rarely found in the head and neck.

Objective:  To describe two cases of a middle ear adenoma with neuroendocrine differentiation, with a literature review.

Case Report:  Patient 1 was a 41-year-old woman who presented with a 3-year history of left aural fullness associated with ipsilateral "hammer beating" tinnitus.

Cochlear implantation through the middle fossa: an anatomic study for a novel technique.

Conclusion: The technique proposed is simple, reliable, and provides sufficient exposure of the basal portion of the cochlea while avoiding disabling complications. It enables visualization of the cochlear basal turn and the osseous spiral lamina, facilitating the insertion of the cochlear implant array through the scala tympani.

Objectives: To describe a novel approach for exposing the cochlear basal turn for cochlear implantation through the middle cranial fossa.

Cochlear implantation through the middle cranial fossa: a novel approach to access the basal turn of the cochlea.

Unlabelled: The classic approach for cochlear implant surgery includes mastoidectomy and posterior tympanotomy. The middle cranial fossa approach is a proven alternative, but it has been used only sporadically and inconsistently in cochlear implantation.

Objective: To describe a new approach to expose the basal turn of the cochlea in cochlear implant surgery through the middle cranial fossa.

Cochlear implants and bacterial meningitis: A speech recognition study in paired samples.

Introduction:  Cochlear implants may guarantee sound perception and the ability to detect speech at a close-to-normal hearing intensity; however, differences have been observed among implantees in terms of performance on discrimination tests and speech recognition.

Objective:  To identify whether patients with post-meningitis deafness perform similarly to patients with hearing loss due to other causes.

Method:  A retrospective clinical study involving post-lingual patients who had been using Nucleus-22 or Nucleus-24 cochlear implants for at least 1 year.
