Summary
Ossicle resorption is common in chronic otitis with cholesteatoma, affecting 82% of patients. Cholesteatoma extension significantly impacts ossicle damage, but audiometry may not reflect the true ossicular chain status.
Area of Science:
- Otolaryngology
- Pathology
- Audiology
Background:
- Chronic otitis with cholesteatoma is a complex condition affecting the middle ear.
- Ossicular chain integrity is crucial for hearing function.
- Understanding factors influencing ossicle damage is vital for patient management.
Purpose of the Study:
- To detail ossicle resorption patterns in chronic otitis with cholesteatoma.
- To correlate ossicle damage with various clinical and pathological parameters.
- To assess the predictive value of clinical factors and audiometry for ossicular status.
Main Methods:
- Retrospective analysis of 140 patients with chronic otitis with cholesteatoma.
- Intraoperative evaluation of ossicle condition.
- Correlation of ossicle resorption with preoperative clinical data (age, contralateral ear, tympanic membrane, cholesteatoma characteristics, associated lesions) and hearing thresholds.
Main Results:
- 82% of patients exhibited ossicle resorption; incus damage occurred in 78%.
- Congenital cholesteatoma and associated lesions invariably led to ossicle damage.
- Cholesteatoma extension was strongly linked to ossicle resorption (p < 0.0001).
- Hearing thresholds worsened with increased ossicle involvement, but the air-bone gap remained stable.
- Pure-tone audiometry and air-bone gap did not reliably indicate the ossicular chain's condition.
Conclusions:
- The origin and location of cholesteatoma correlate with the site of ossicular damage.
- Ossicular damage is a consequence of direct contact between cholesteatoma and bone.
- Preoperative clinical parameters and standard audiometry are insufficient predictors of ossicular chain integrity in cholesteatoma.

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...

01:13The 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.
01:16Anatomy 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...
01:15Auditory Pathway
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.
