Acoustic neuroma is one of the most common tumors of the posterior cranial fossa. Its removal is always a challenge for the neurosurgeon and the patient. The history of surgery for acoustic neuromas is inextricably linked with the history of neurosurgery in general. The modern surgical community must know history and be able to use it. Only then will the development of surgery lead to the preservation of the quality of life of patients. In the history of surgery for acoustic neuromas, the stages of its development are clearly visible from the description of the clinical picture through the study of the anatomy of the cerebellopontine angle to modern microsurgical removal.

This study (1) characterized the effects of channel interaction using spectral blurring, (2) evaluated an image-guided electrode selection (IGES) method aiming to reduce channel interaction, and (3) investigated the impact of electrode placement factors on the change in performance by condition. Twelve adult MED-EL (Innsbruck, Austria) cochlear implant recipients participated. Performance was compared across six conditions: baseline (no blurring), all blurred, apical blurred, middle blurred, basal blurred, and IGES.

Previous studies of laryngeal and respiratory control of the voice source often focus on main effects of individual control parameters but not their interactions. The goal of this study is to systematically identify important interaction effects in laryngeal and respiratory control of the voice source and vocal fold contact pressure in a three-dimensional voice production model. Computational simulations were performed with parametric variations in vocal fold geometry, stiffness, prephonatory glottal gap, and subglottal pressure.

Background: Surgery for tumors in the cerebellopontine angle is always a significant challenge due to the densely packed neurovascular structures, the narrow deep location, and the complex relationship between the lesions and surrounding neurovascular structures. Recently, great attention has been given to the neuroendoscope for its exclusive advantages, which have added a new dimension to many classical microscopic surgeries. However, the feasibility and advisability of fully endoscopic neurosurgery for cerebellopontine angle tumors remain to be further evaluated.

Introduction And Importance: Hydatid disease, caused by the Echinococcus parasite, is a significant health concern in endemic regions. While commonly found in the liver and lungs, breast involvement is rare. We present a case of a hydatid cyst in the breast of a 34-year-old woman from Ethiopia, initially suspected to be breast cancer.

This study aimed to compare the effects of cochlear implantation(CI) on vestibular function in patients with large vestibular aqueduct syndrome(LVAS) and in patients with extremely severe deafness with normal inner ear structure. A total of 28 LVAS patients and 28 patients with normal inner ear structure who suffered from extremely severe deafness were selected. The parameters of caloric tests, bone conduction evoked cervical vestibular-evoked myogenic potentials(cVEMP), bone conduction evoked ocular vestibular-evoked myogenic potentials(oVEMP) and video head impulse tests(v-HIT) were compared between the two groups before and after CI.
