H90.A11
Conductive hearing loss, unilateral, right ear with restricted hearing on the contralateral side
Clinical Classification Guidelines
Medical Intelligence & Overview
Unilateral conductive hearing loss refers to a condition where hearing ability is diminished in one ear due to issues in the ear's ability to carry sound signals properly. Specifically, ICD-10 Code H90.A11 describes cases where the right ear experiences hearing loss caused by conductive factors, and there is also restricted hearing on the opposite (contralateral) side. This condition can impact communication, spatial awareness, and quality of life, making it important to recognize and understand its causes, symptoms, diagnosis, and treatment options.
Causes & Symptoms
Clinical Causes: Ear infections (otitis media) leading to fluid buildup in the middle ear Otosclerosis, which causes abnormal bone growth around the inner ear structures Eardrum perforation following injury or infection Congenital abnormalities affecting the ear structure Presence of earwax (cerumen impaction) blocking the ear canal Malleus, incus, or stapes abnormalities Tumors or growths in the middle ear, such as cholesteatoma Trauma or injury to the ear or head Eustachian tube dysfunction preventing normal ear pressure regulation
Key Symptoms: Hearing difficulty in the affected (right) ear, especially in noisy environments Sounds may seem muffled or less clear Difficulty understanding speech, particularly when multiple people speak at once Possible sensation of fullness or pressure in the affected ear Reduced hearing sensitivity on the contralateral side, which may manifest as a restricted or diminished perception of sound Tinnitus (ringing or buzzing in the affected ear) Balance issues or dizziness in some cases
Diagnostic & Treatment
Diagnosis Path: Diagnosing unilateral conductive hearing loss typically involves comprehensive audiological testing, including pure-tone audiometry to assess hearing thresholds in each ear separately. An ear examination, possibly with an otoscope, helps identify physical issues such as earwax buildup, eardrum perforation, or abnormal bone growth. Additional tests like tympanometry evaluate middle ear function. Imaging studies such as CT scans may be utilized to visualize the structures of the middle and inner ear and to detect any anatomical anomalies or tumors. A healthcare specialist, often an otolaryngologist (ENT doctor), conducts these assessments to determine the precise cause and extent of hearing loss.
Treatment Protocols: Removing earwax or foreign objects to clear the ear canal Treating infections with antibiotics or other medications Surgical procedures such as myringoplasty to repair eardrum perforations Stapedectomy or stapedotomy for otosclerosis to restore hearing Placement of middle ear implants or hearing aids to amplify sound Addressing Eustachian tube dysfunction with balloon dilation or other measures Tumor removal surgeries if growths are present Managing trauma-related injuries with appropriate medical care
