Amyloidosis is an idiopathic disease that is characterized by the extracellular deposition of fibrillar proteins. The disease can be categorized as primary or secondary where deposits occur in conjunction with chronic diseases such as rheumatoid arthritis or tuberculosis. The deposits can be localized or systemically distributed. It can mimic, and also be associated with underlying malignancy. Primary amyloidosis is a rare cause of a nasopharyngeal lesion, and less so of a secondary middle ear effusion. Its association with underlying chronic and malignant disease must not be over-looked if serious complications are to be avoided. It is, therefore, important to consider this as a differential diagnosis in such patients.

Novel continuous and quantitative intraoperative facial nerve-monitoring system for temporal bone lesions.
Eur Arch Otorhinolaryngol

Objective: Intraoperative systems for monitoring facial nerve function, in which temporal electrical stimulation is applied to the facial nerve through electrodes, are used in many surgeries requiring facial nerve preservation; however, continuous stimulation or quantitative evaluation of facial nerve function is difficult with this approach. We examined the usefulness of a continuous and quantitative facial nerve-monitoring system for temporal bone lesions by using our experience to modify the existing methods used for cases involving vestibular schwannomas.
Study Design: Retrospective observational study.

Purpose: Tympanoplasty is a surgical procedure performed to cure middle ear infections and restore normal middle ear function. It is one of the most common procedures in otological surgery. Since Wullstein described tympanoplasty, the microscope has been a widely used surgical tool in otological surgery.

Gravitational changes have been shown to cause significant abnormalities in various body systems, including the cardiovascular, immune, vestibular, and musculoskeletal systems. While numerous studies have examined the response of the vestibular system to gravitational stimulation, research on functional changes in the peripheral inner ear remains limited. The inner ear comprises two closely related structures: the vestibule and cochlea.

Background/objectives: The gene is responsible for autosomal recessive non-syndromic sensorineural hearing loss and is assigned as DFNB18B. To date, 44 causative variants have been reported to cause non-syndromic hearing loss. However, the detailed clinical features for -associated hearing loss remain unclear.
