H90.A3
Mixed conductive and sensorineural hearing loss, unilateral with restricted hearing on the contralateral side
Clinical Classification Guidelines
Medical Intelligence & Overview
Unilateral mixed hearing loss, classified under ICD-10 code H90.A3, is a condition where a person experiences both conductive and sensorineural hearing impairments in one ear. The term 'mixed' signifies that the hearing loss involves both problems in sound conduction through the ear and issues with inner ear or nerve function. Additionally, the opposite ear may have restricted hearing capabilities, impacting overall hearing ability and clarity. Recognizing the nature of this condition is crucial for appropriate management and treatment planning.
Causes & Symptoms
Clinical Causes: Chronic ear infections leading to damage of middle or inner ear structures Aging-related deterioration of auditory components Trauma or injury affecting the ear or head Genetic factors influencing ear development or function Exposure to loud noises causing sensorineural damage Ear tumors or growths obstructing sound conduction or damaging nerve pathways Congenital anomalies present from birth that affect ear functionality Otosclerosis, leading to abnormal bone growth in middle ear Previous ear surgeries or radiation therapy impacting ear structures
Key Symptoms: Difficulty understanding speech, especially in noisy environments Perception of muffled or distorted sounds Reduced ability to hear high-frequency sounds Feeling of fullness or pressure in the affected ear Possible dizziness or imbalance in some cases Restricted hearing on the opposite ear, affecting overall sound clarity Tinnitus, or ringing in the affected ear
Diagnostic & Treatment
Diagnosis Path: imaging studies like MRI or CT scans to identify structural abnormalities or tumors. The combination of test results helps determine the specific type and extent of hearing loss, guiding treatment options.
Treatment Protocols: Medication such as antibiotics or anti-inflammatory drugs for infections Surgical interventions to repair damages, remove growths, or correct structural issues in the ear Hearing aids designed to amplify sound and improve hearing clarity in the affected ear Cochlear implants or other auditory rehabilitation devices for severe sensorineural loss Assistive listening devices to enhance hearing ability in specific situations Counseling and communication strategies to cope with hearing difficulties
Clinical Advice & FAQs
Billing Guidance
