Anatomy of the Ear

Anatomy of the Ear

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

Equilibrium and Balance

Equilibrium and Balance

The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Olfactory Receptors: Location and Structure

Olfactory Receptors: Location and Structure

The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

The Cochlea

The Cochlea

The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.

Unrenewable Cells

Unrenewable Cells

In humans, the photoreceptor cells of the eye and sensory hair cells of the ear lack stem cells. These cells are thus unrenewable and cannot be replaced when they are damaged or destroyed.
Photoreceptors
The retina is composed of several layers and contains specialized cells called photoreceptors. The photoreceptors (rods and cones) change their membrane potential when stimulated by light energy. There are two types of photoreceptors—rods and cones—which differ in the shape of their outer...

Brain Abscess l: Introduction

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...

Summary

Vestibular symptoms in chronic otitis media (COM) can be assessed using vestibular-evoked myogenic potential (VEMP) tests. These tests, alongside audiometry, help detect inner ear deficits in COM patients.

Background:

Vestibular symptoms in chronic otitis media (COM) are challenging to investigate due to contraindications for standard caloric tests in perforated ears.
Evaluating inner ear function in COM patients requires alternative diagnostic methods.

Purpose of the Study:

To assess inner ear deficits in patients with COM using audiometry, ocular vestibular-evoked myogenic potential (oVEMP), and cervical VEMP (cVEMP) tests.
To determine the sequence of inner ear dysfunction in COM.

Main Methods:

Audiometry, ocular vestibular-evoked myogenic potential (oVEMP), and cervical VEMP (cVEMP) tests were performed on 85 COM patients (117 ears).
Otoscopy and imaging studies were also conducted.
Bone-conducted (BC) hearing thresholds were analyzed.

Main Results:

Abnormal BC hearing thresholds were found in 37% of ears.
Abnormalities were observed in 65% of cVEMP tests, 62% of oVEMP tests, and 37% of BC hearing thresholds, indicating a decline in inner ear function.
cVEMP and oVEMP results correlated significantly with BC hearing thresholds.

Conclusions:

The sequence of inner ear deficits in COM progresses from the saccule/utricle to the cochlea and semicircular canals.
cVEMP and oVEMP tests, in addition to BC hearing tests, can aid in the early detection of inner ear involvement in COM patients.
