H90.72
Mixed conductive and sensorineural hearing loss, unilateral, left ear, with unrestricted hearing on the contralateral side
Clinical Classification Guidelines
Medical Intelligence & Overview
Mixed hearing loss is a type of hearing impairment that involves both conductive and sensorineural components. When it affects only one ear—referred to as unilateral—it can influence your hearing ability, communication, and overall quality of life. Specifically, ICD-10 code H90.72 describes a case where the left ear experiences both conductive and sensorineural hearing loss, while the right ear maintains normal hearing. Recognizing and understanding this condition is important for managing its effects effectively.
Causes & Symptoms
Clinical Causes: Chronic ear infections or otitis media causing damage to ear structures Ear trauma or injury affecting the middle or inner ear Noise exposure leading to inner ear damage Age-related hearing decline (presbycusis) Meniere's disease or other inner ear disorders Ototoxic medications damaging auditory components Congenital anomalies or malformations in ear structures Tumors such as vestibular schwannoma impacting the auditory nerve Sudden sensorineural hearing loss due to various causes
Key Symptoms: Difficulty hearing sounds distinctly from the affected left side Reduced clarity in speech understanding, especially in noisy environments Perception of a muffled or hollow sound in the affected ear Potential balance issues or dizziness A ringing or buzzing sensation (tinnitus) in the affected ear Feeling of fullness or pressure in the ear Noticeable difference in hearing between the two ears
Diagnostic & Treatment
Diagnosis Path: Diagnosing mixed hearing loss involves a combination of clinical assessments and testing procedures, such as: - **Pure-tone audiometry**: Measures hearing thresholds across different frequencies in each ear. - **Speech audiometry**: Assesses clarity and understanding of speech sounds. - **Tympanometry**: Evaluates middle ear function and detects fluid or structural abnormalities. - **Imaging studies**: MRI or CT scans, particularly if a tumor or structural anomaly is suspected. - **Otoacoustic emissions and auditory brainstem response tests**: Help determine inner ear and nerve function. Healthcare providers interpret these results to confirm the presence of both conductive and sensorineural components and to plan appropriate management.
Treatment Protocols: Management of mixed hearing loss in the left ear depends on the underlying cause and severity of the condition. Possible options include: - **Hearing aids**: Amplify sounds to improve hearing, particularly effective if the impairment is mild to moderate. - **Medical treatment**: - Antibiotics or anti-inflammatory medications for infections. - Surgical interventions such as ossiculoplasty or tympanoplasty to repair ear structures. - Removal of tumors if identified as the cause. - **Assistive listening devices**: Utilize in specific situations to enhance hearing. - **Rehabilitation**: Audiologic therapy to adapt to hearing challenges. - **Monitoring**: Regular check-ups to assess the progression or improvement of hearing loss. In some cases, if the loss is profound and not amenable to conventional treatments, cochlear implants or other assistive technologies may be considered.
