Summary
Oculo-auriculo-vertebral spectrum, or Goldenhar syndrome, frequently causes conductive hearing loss, particularly in the right ear. Early audiological assessment is crucial for speech therapy and intervention in affected individuals.
Area of Science:
- Genetics and developmental biology
- Audiology and otolaryngology
Background:
- Oculo-auriculo-vertebral spectrum (OAVS), also known as Goldenhar syndrome, involves developmental abnormalities of the first and second branchial arches.
- Key features include craniofacial, ocular, auricular, and vertebral anomalies, with auricular abnormalities often linked to hearing impairment.
Purpose of the Study:
- To investigate the audiological profile of patients diagnosed with OAVS.
- To analyze hearing loss patterns using pure-tone and speech audiometry.
Main Methods:
- A cross-sectional study involving 10 patients with OAVS, exhibiting clinical signs in at least two affected areas.
- Comprehensive audiological evaluations, including liminal pure-tone audiometry and speech audiometry, were performed on all participants.
Main Results:
- All 10 patients presented with ear abnormalities, predominantly affecting the right side.
- Conductive hearing loss was the most prevalent type (10 ears), followed by sensorineural (5 ears) and mixed hearing loss (1 ear).
- Hearing impairment severity ranged from mild to moderate, with one instance of profound hearing loss.
Conclusions:
- Individuals with OAVS show a high incidence of conductive hearing loss, often moderate and affecting the right ear.
- Understanding auditory thresholds in OAVS is vital for effective speech therapy and timely intervention for hearing-related issues.

01:11The Auditory Ossicles

The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

01:29The Vestibular System
45.4K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

01:28Physical Assessment of the Respiratory Tract IV: Auscultation
3.6K
Auscultation is a crucial component of the physical assessment of the respiratory tract. It offers valuable insights into airflow through the bronchial tree and potential lung obstructions. This process involves careful listening to breath, voice, and adventitious sounds, which can reveal a wealth of information about a patient's respiratory health.
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.
