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.

Differential Biases and Variabilities of Deep Learning-Based Artificial Intelligence and Human Experts in Clinical Diagnosis: Retrospective Cohort and Survey Study.

Background: Deep learning (DL)-based artificial intelligence may have different diagnostic characteristics than human experts in medical diagnosis. As a data-driven knowledge system, heterogeneous population incidence in the clinical world is considered to cause more bias to DL than clinicians. Conversely, by experiencing limited numbers of cases, human experts may exhibit large interindividual variability.

Simultaneous Nonmastoidectomy Infrapromontorial Tumor Removal and Cochlear Implantation in Vestibular Schwannoma Patient.

Introduction: Restoration of hearing in patients with vestibular schwannoma (VS) and poor hearing poses a great challenge. Simultaneous cochlear implantation during surgery for VS removal offers favorable hearing outcome if the cochlear nerve remains intact. Recent refinement of surgical techniques using the endoscope has made it possible to simultaneously restore the hearing and remove the tumor.

One-stage cochlear implantation in patients with chronic otitis media using canal wall up mastoidectomy.

Background: Cochlear implantation (CI) with subtotal petrosectomy was recommended to avoid the complications for patients with chronic otitis media (COM).

Objectives: To evaluate the surgical outcomes of CI in patients with COM using a one-stage operation with canal wall up mastoidectomy (CWUM).

Methods: Thirty-five patients with COM who underwent CI with CWUM as a one-stage between 2009 and 2017 were participated.

Comparison of Clinical Characteristics and Surgical Outcomes of Cystic and Solid Vestibular Schwannomas.

Objective: The aim of this study was to compare the clinical characteristics of cystic vestibular schwannomas (CVSs) and solid vestibular schwannomas (SVSs).

Study Design: Retrospective review.

Setting: Tertiary care center.
