Summary
Children with cleft palate face a high risk of auditory processing disorders, particularly difficulty understanding speech in noisy environments. Early speech therapy may help some auditory issues, but challenges with speech intelligibility in noise persist across all age groups.
Area of Science:
- Audiology
- Speech-Language Pathology
- Pediatric Otolaryngology
Background:
- Patients with cleft palate frequently experience recurrent otitis media with effusion in infancy.
- This can lead to binaural conductive hearing loss, a risk factor for auditory processing disorders.
- Limited research exists on auditory processing in this patient group.
Purpose of the Study:
- To investigate auditory processing disorders in patients with various cleft palate manifestations.
- To compare findings within an own patient cohort to existing studies.
Main Methods:
- Included 48 patients (5-16 years) with non-syndromic cleft palate and normal peripheral hearing.
- Evaluated using otoscopy, pure tone audiometry, speech intelligibility in noise, dichotic speech discrimination, auditory short-term memory, and a parental questionnaire.
Main Results:
- Most parents reported no issues; however, 69% of participants showed deficits in speech intelligibility in noise.
- Dichotic speech discrimination and auditory short-term memory were impaired in 16.7% of participants, primarily younger children.
- Speech intelligibility in noise deficits were observed across all age groups.
Conclusions:
- Children and adolescents with cleft palate are susceptible to auditory processing disorders.
- Speech intelligibility in noise was the most prevalent issue in this cohort.
- While speech therapy may mitigate some auditory deficits, it did not fully resolve speech intelligibility in noise problems.

6.7K
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.

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.

01:17Auditory Perception

The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...

01:11The Auditory Ossicles
2.7K
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...

01:13The Cochlea
49.6K
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.

The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...
