ICD-10: H90.6

ICD-10 code H90.6 refers to "Mixed conductive and sensorineural hearing loss, bilateral." This classification is part of the broader category of hearing loss codes under the H90 series, which encompasses various types of hearing impairments. Below is a detailed clinical description and relevant information regarding this specific diagnosis.

Clinical Description

Definition

Mixed hearing loss is characterized by the simultaneous presence of conductive hearing loss and sensorineural hearing loss. Conductive hearing loss occurs when sound waves are not efficiently conducted through the outer ear canal to the eardrum and the tiny bones of the middle ear. Sensorineural hearing loss, on the other hand, results from damage to the inner ear (cochlea) or the auditory nerve pathways to the brain. When both types of hearing loss occur together, it is classified as mixed hearing loss.

Bilateral Implications

The term "bilateral" indicates that the hearing loss affects both ears. This can lead to significant challenges in sound localization, communication, and overall auditory perception. Patients may experience varying degrees of hearing impairment in each ear, which can complicate diagnosis and treatment.

Clinical Features

Symptoms

Patients with mixed conductive and sensorineural hearing loss may exhibit a range of symptoms, including:
- Difficulty hearing soft sounds
- Trouble understanding speech, especially in noisy environments
- A sensation of fullness or pressure in the ears
- Tinnitus (ringing or buzzing in the ears)
- Variability in hearing ability, depending on the environment

Causes

The causes of mixed hearing loss can be diverse and may include:
- Chronic ear infections leading to conductive loss
- Otosclerosis (abnormal bone growth in the middle ear)
- Age-related changes affecting both the conductive and sensorineural components
- Noise exposure that damages the inner ear while also affecting the outer or middle ear structures
- Genetic factors that predispose individuals to both types of hearing loss

Diagnosis and Evaluation

Audiological Assessment

Diagnosis typically involves a comprehensive audiological evaluation, which may include:
- Pure-tone audiometry to assess hearing thresholds
- Speech audiometry to evaluate speech recognition abilities
- Tympanometry to assess middle ear function
- Otoacoustic emissions (OAEs) to evaluate cochlear function

Imaging Studies

In some cases, imaging studies such as CT or MRI may be warranted to identify structural abnormalities in the ear that could contribute to mixed hearing loss.

Treatment Options

Medical Management

Treatment may involve:
- Medical interventions for underlying conditions (e.g., antibiotics for infections)
- Surgical options for conductive components (e.g., tympanoplasty or stapedectomy)

Audiological Rehabilitation

For sensorineural components, audiological rehabilitation may include:
- Hearing aids to amplify sound
- Cochlear implants for severe cases
- Auditory training and counseling to improve communication strategies

Conclusion

ICD-10 code H90.6 encapsulates a complex condition that requires a multidisciplinary approach for effective management. Understanding the dual nature of mixed conductive and sensorineural hearing loss is crucial for audiologists, otolaryngologists, and other healthcare providers involved in the care of affected individuals. Early diagnosis and appropriate intervention can significantly enhance the quality of life for patients experiencing this type of hearing loss[1][2][3][4][5].
