Subjective Visual Vertical Can be an Effective Tool to Evaluate Vestibular Function of Stapedotomy

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective To investigate if the subjective visual vertical/horizontal (SVV/SVH) can be used to evaluate the otolith organ of otosclerosis and stapedotomy. Design A total of 19 patients who were diagnosed with otosclerosis and underwent surgical treatment in our hospital were collected.

Benign Paroxysmal Positional Vertigo: Concomitant Involvement of Different Semicircular Canals

, 2009
Objectives: We evaluated the simultaneous ipsilateral or contralateral involvement of the posterior and lateral, anterior and lateral, or posterior and anterior semicircular canals in patients with benign paroxysmal positional vertigo (BPPV).Methods: The

Anatomical Characteristics of the Facial Nerve in Patients With Cochlear Hypoplasia

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective To quantitatively characterize the spatial relationships between intratemporal facial nerve segments and key cochlear implantation (CI) landmarks in cochlear hypoplasia (CH), and to compare these features with age‐matched CI recipients with normal inner ear anatomy, thereby informing preoperative planning and facial nerve ...

Unveiling Otolith Mystery: Contemporary Testing Approaches and Their Clinical Significance

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective Otolith is a critical component of the peripheral vestibular system responsible for detecting linear acceleration. Dysfunction of the otolith organs can lead to vertigo, balance disturbances, and gaze instability. By elucidating the physiological foundations and evaluating both current and emerging methods for assessing otolith ...

Why the semicircular canals are not stimulated by linear accelerations

, 2019
: Head accelerations are sensed by the vestibular system in the inner ear. Linear accelerations stimulate the otolith organs, while the semicircular canals (SCC) sense angular accelerations.

Orientation and Orthogonality of the Semicircular Canals in the Cheetah (Acinonyx jubatus) [PDF]

The purpose of this study was to clarify the spatial orientation of the semicircular canals in the cheetah (Acinonyx jubatus) using computed tomography (CT). CT scan was performed on the skull of a cheetah. Scanning data were reconstructed into the cross-

NMDA receptors in frog semicircular canals

, 1993
The effects of competitive (2-amino-5-phosphonovaleric acid) and noncompetitive (Mg2+, ketamine and kynurenic acid) NMDA receptor antagonists were tested in isolated semicircular canals of the frog.

Therapeutic efficacy of the Galletti–Contrino manoeuvre for benign paroxysmal positional vertigo of vertical semicircular canals in overweight subjects

, 2018
Objective: To compare the Galletti–Contrino manoeuvre with the more widely used Semont–Toupet in overweight subjects presenting with benign paroxysmal positional vertigo (BPBV) of vertical semicircular canals (posterior and anterior canals). Study design:

Unravelling the phylogeny of armadillos and their kin (Mammalia, Xenarthra, Cingulata) combining morphological, molecular, and stratigraphic data

Cladistics, EarlyView.
Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological
