Simultaneous Translabyrinthine Vestibular Schwannoma Removal and Cochlear Implantation: Assessment of Wireless Connection Speech Test.

Objective: Simultaneous vestibular schwannoma (VS) removal via the translabyrinthine approach (TLA) and cochlear implantation (CI) allows for overlapping surgical fields, improving postoperative hearing outcomes, and minimizing complications associated with multiple surgical interventions. However, the effectiveness of this surgical approach remains a topic of debate. To address this, we aim to evaluate surgical outcomes using an objective wireless connection speech test to ensure accurate auditory performance.

Butterfly Cartilage Inlay Technique for Repairing Medium-to-Large-Sized Tympanic Membrane Perforations.

Objective: The butterfly cartilage inlay technique was originally developed for repairing small tympanic membrane (TM) perforations but is now increasingly used for repairing large TM perforations. Although studies have evaluated the effectiveness of butterfly tympanoplasty for repairing medium-to-large-sized TM perforations, no study has compared its effectiveness with that of the conventional underlay cartilage technique. Therefore, we aimed to evaluate the effectiveness of butterfly tympanoplasty for repairing medium-to-large-sized TM perforations compared with that of the conventional underlay cartilage.

Clinico-Radiological Manifestations of Cochlear Schwannomas.

Background And Objectives: Cochlear schwannomas, which are categorized into intracochlear and intravestibulocochlear schwannomas (ICs and IVCs, respectively) are rare and may cause hearing loss (HL). The affected region is invariably correlated with tumor location, which can be detected on magnetic resonance imaging (MRI). We describe the cochleovestibular manifestations of ICs and IVCs.

Consensus Statement: Postoperative Management After Balloon Dilation of the Eustachian Tube.

Objectives: Balloon dilation of the Eustachian tube (BDET) is widely recognized as a minimally invasive treatment for obstructive Eustachian tube dysfunction (ETD). We employed a Delphi consensus methodology to develop recommendations for the clinical management of BDET in cases of obstructive ETD.

Methods: A Delphi panel consisting of 26 expert physicians specializing in otology participated in two rounds of anonymous, iterative questionnaires.

The international expert consensus on management of external auditory canal carcinoma.

Purpose: The objective of this consensus is to provide otolaryngologists with appropriate strategies in the management of external auditory canal (EAC) carcinoma.

Methods: In the absence of randomized controlled trials, the consensus is based on expert opinions utilizing the Rand/UCLA appropriateness method [Fitch and Aguilar in The RAND/UCLA appropriateness method user's manual, RAND Corporation, Santa Monica, CA, 2001], drawing from existing literature and clinical experience.

Results: The management recommendations are structured around 12 key areas, including: definition and pathology, pathogenesis, clinical manifestations, work-up, tumor staging system, surgical management of primary tumor, surgical management of the parotid gland and the temporomandibular joint, lymph node metastasis, radiotherapy, chemotherapy, reconstruction, and follow-up.

Simultaneous cochlear implantation with early endoscopic surgery in small acoustic neuroma.

Objectives: The exclusive endoscopic transcanal transpromontorial approach (EETTA) has recently been developed for the removal of small-sized acoustic neuromas in the labyrinth (intralabyrinthine schwannoma [ILS]) or internal auditory canal (IAC). Although small tumors that meet the indications for EETTA are also good candidates for cochlear implantation (CI), there are few reports on CI after schwannoma removal using EETTA. Here we present an outcome of patients who underwent simultaneous EETTA and CI.

Tailored re-roofing technique for pulsatile tinnitus caused by sigmoid sinus dehiscence or diverticulum.

Background: Sigmoid sinus diverticulum/dehiscence (SSD) is one of the treatable causes of venous pulsatile tinnitus. It can be diagnosed using temporal bone computed tomography (CT) or magnetic resonance angiography/venography (MRA). In cases where patients find their symptoms intolerable, surgical treatment is typically preferred.

Interpretation of the nine-step test for Eustachian tube function should consider mastoid cavity volume.

Introduction: The modified nine-step test is a classical method for evaluating Eustachian tube function. However, clinical interpretation of the increased maximal difference in middle ear pressure (mdMEP) in the modified nine-step test is unknown. We hypothesised that the different reservoir effects of the mastoid cavity can bias the results of the modified nine-step test.

Long-term follow-up results of facial nerve schwannoma with good facial nerve function: a multicenter study.

Purpose: Facial nerve schwannomas (FNSs) are rare intracranial tumors, and the optimal management of these tumors remains unclear. We investigated the long-term follow-up results of FNS with good facial nerve function.

Methods: At nine medical centers in the Korean Facial Nerve Study Group, 43 patients undergoing observation periods longer than 12 months for FNS with good facial nerve function (House-Brackmann grade ≤ II) were enrolled, and clinical and radiographic data were obtained for these cases.

Consensus Statements on the Definition, Classification, and Diagnostic Tests for Tinnitus: A Delphi Study Conducted by the Korean Tinnitus Study Group.
