H91.11

Clinical Causes: Age-related degeneration of hair cells in the cochlea Loss of sensory cells and nerve fibers in the inner ear Changes in the inner ear's blood supply Accumulation of metabolic waste affecting auditory structures Genetic predispositions to hearing decline Environmental factors such as prolonged exposure to loud noises

Key Symptoms: Gradual decrease in hearing acuity in the right ear Difficulty understanding speech, especially in noisy environments Perception of muffled or distorted sounds Difficulty distinguishing high-frequency sounds like consonants Sounds seeming less loud or clear over time Potential ringing or buzzing in the affected ear

Diagnosis Path: Diagnosing presbycusis involves a comprehensive hearing assessment, including audiometry tests that measure hearing thresholds across various frequencies. A healthcare professional will evaluate the patient's medical history, inquire about exposure to noise, and assess their overall ear health. Additional tests, such as otoacoustic emissions or auditory brainstem response tests, may be employed to evaluate inner ear and nerve function. An ear examination can help rule out other causes like wax buildup or infections that could mimic or contribute to hearing loss.

Treatment Protocols: While presbycusis cannot be reversed, several management options can help improve hearing and communication. These include the use of hearing aids tailored to enhance sound perception in the affected ear, assistive listening devices, and communication strategies like speech reading or auditory training. Additionally, protecting the ears from further damage by avoiding loud noises and using hearing protection is advisable. Regular hearing evaluations are recommended to adjust treatment plans as needed. In some cases, medical or surgical interventions may be considered if other underlying issues are identified.
