Outcomes of Cartilage Tympanoplasty in Children

This study evaluates the anatomical and hearing outcomes of cartilage tympanoplasty in pediatric patients with chronic tympanic membrane perforations. A perforation (hole) in the eardrum in children can lead to recurrent ear discharge, chronic middle-ear infections, and conductive hearing loss. Cartilage tympanoplasty is a surgical technique that uses autologous cartilage (the patient's own cartilage tissue) to reconstruct and seal the eardrum. Cartilage is known for its rigidity and resistance to retraction, which may offer advantages in children who frequently experience middle-ear pressure and ventilation issues. Children aged 8 to 18 years presenting with large, subtotal, or persistent dry central perforations will undergo cartilage tympanoplasty at Assiut University Hospitals. All participants will undergo standardized pre-surgical and post-surgical evaluations, including otological microscopic examinations and pure-tone audiometry tests. The main objectives are to evaluate the graft success rate (complete anatomical closure and stability of the eardrum) and to measure functional hearing restoration, specifically changes in air-conduction thresholds and the air-bone gap (ABG).

Evaluation of Flexible Conductive Hearing Aids

Conductive hearing loss (CHL) is the most common type of hearing loss among the pediatric population. CHL occurs when sound is not properly transmitted from the external ear to the cochlea, and congenital pathologies like microtia/anotia, atresia, and absent or malformed ossicles make hearing loss permanent.

Middle Ear Optical Coherence Tomography Imaging and Vibrometry in Patients With Hearing Loss

This study involves imaging ears with hearing loss with a new system that allows the user to see the middle ear bones and measure their movement in response to sound.
