Vestibular organs consist of the maculae staticae, which are located in both the utricle and saccule, as well as the semicircular ducts and their ampullas. There have been no reports on specimen preparation methods for vestibular organs, including maculae staticae or semicircular ducts. In this study, we investigated highly reproducible methods of preparing vestibular organ specimens for histopathological examinations. We established a method that allows researchers to observe the utricle and saccule, including otoliths, the ampulla of a semicircular duct, and parts of semicircular ducts. This highly reproducible method is useful for histopathological analysis of mice with symptoms of abnormal equilibrium caused by medical toxicity and genetic modification.

The connective tissue support of female pelvic viscera-endopelvic fascia-has been studied in fetal and immunohistochemical models to demonstrate its relationship with the autonomic nerves of the female pelvis. Due to a paucity of literature examining the gross anatomical relationships between endopelvic fascia and autonomic nerves in adult female pelvises, it remains unknown whether defects in endopelvic fascia predisposing pelvic organ prolapse and/or manipulation of endopelvic fascia during prolapse repair may be the cause of prolapse-related pelvic pain and sexual dysfunction. Through the dissection of formalin-fixed hemipelvises (n = 10) the present study aimed to map the loci of the visceral branches of the inferior hypogastric plexus and associate them with endopelvic fascia of the female pelvis.

Aim: Diabetes mellitus (DM), a systemic disease, is a major public health concern. It is possible that micro and macrovascular changes in the inner ear due to DM could affect both auditory and vestibular functioning. However, there is a lack of conclusive evidence for vestibular impairment in individuals with DM.

Background: The vestibular system is crucial for balance and gaze stability. Proprioceptive inputs from the musculoskeletal system significantly contribute to vestibular processing, especially under postural challenge.
Objectives: To examine how proprioceptive inputs in various body positions affect the vestibulo-ocular reflex (VOR) and otolith organ function.

: Waardenburg syndrome (WS) is a genetic disorder characterized by sensorineural hearing loss (SNHL) and pigmentation anomalies. While hearing impairment is a well-established feature of WS, vestibular dysfunction is also reported. This study aimed to investigate vestibular deficits in pediatric WS patients with SNHL, correlating these findings with molecular, audiometric, and radiological data to establish distinct phenotypic profiles for each WS subtype and associated pathogenic variants.

Purpose: In the fields of both vestibular and auditory research, reliable vestibular function tests are essential. However, unlike the auditory function tests, which use standard Auditory Brainstem Response (ABR) equipment, there is no equivalent widely adopted apparatus for vestibular tests. Vestibulo-ocular reflexes (VORs) are the compensatory ocular reflexes that ensure stable vision during head motion.
