OBJECTIVES/HYPOTHESIS The purpose of the study was to investigate whether cochlear implantation using the round window approach provided better preservation of residual hearing than the cochleostomy approach. STUDY DESIGN Case-control study. METHODS We designed a case-control study including 40 patients from a tertiary referral center who underwent cochlear implantation surgeries using devi...

UNLABELLED A new era has arrived in auditory rehabilitation with the introduction of new technologies such as electroacoustic stimulation (EAS). EAS is indicated for patients with residual hearing at low frequencies and severe or profound hearing loss at high frequencies. These patients have no indication for conventional cochlear implant and have difficulties in adapting to individual sound am...

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 w...

OBJECTIVE The aim of the study was to compare the surgical and functional outcomes of the microsurgical osteoplastic retro-sigmoid approach in a semi-sitting position in two groups of patients with vestibular schwannomas (VSs) ranging from 1 to 3 cm in size. METHOD A 5-year retrospective evaluation was made of these two groups of patients with VS: Patients with VS sizes 1-<2 cm in maximal int...

Objectives To describe a unique case report of a patient who had partial hearing preservation after translabyrinthine (TL) removal of a vestibular schwannoma (VS). Study Design Case report. Methods The patient's chart was reviewed for hearing levels before and after surgery. Preoperative magnetic resonance imaging (MRI) was compared with postoperative MRI for determination of completeness of tu...

OBJECTIVE Neurofibromatosis type 2 (NF2) is an autosomal dominant disease characterized by bilateral vestibular schwannomas (VSs). NF2-associated VSs (NF2-VSs) are routinely treated with microsurgery; however, stereotactic radiosurgery (SRS) has emerged as an effective alternative in recent decades. To elucidate the role of SRS in NF2-VSs, a systematic review of the literature was conducted to ...

BACKGROUND Single-session stereotactic radiosurgery (SRS) treatment of vestibular schwannomas results in excellent tumor control. It is not known whether functional outcomes can be improved by fractionating the treatment over multiple sessions. OBJECTIVE To examine tumor control and complication rates after multisession SRS. METHODS Three hundred eighty-three patients treated with SRS from ...

Between 1981 and 1984, 44 patients underwent acoustic neuroma removal by a posterior cranial fossa approach in an attempt to preserve hearing. 7 tumors were small (less than 20 mm), 28 were medium (20 to 40 mm) and 9 large (greater than 40 mm). Of these 44 patients, 4 had normal hearing preoperatively, 15 had serviceable hearing, 10 poor hearing and 15 no hearing. Postoperative hearing was pres...

E-mail: [email protected] Advances in anesthesia and surgical techniques have brought the surgical mortality rate for vestibular schwannomas (VS) to less than 1%. Increased preservation rates of facial and cochlear function were observed in the most recent...
