ICD-10: H93.221

Diplacusis is a fascinating auditory phenomenon characterized by the perception of a single sound as two distinct pitches. This condition can significantly affect an individual's hearing experience, particularly when it occurs in one ear, such as the right ear in the case of ICD-10 code H93.221.

Clinical Description of Diplacusis

Definition and Types

Diplacusis can be classified into two main types:
1. Diplacusis Dissonans: This type occurs when a sound is perceived as two different pitches in the affected ear, leading to a dissonant auditory experience.
2. Diplacusis Echoica: In this variant, the sound is perceived as two pitches that are not only different but also occur at different times, creating an echo-like effect.

Symptoms

Individuals with diplacusis may experience:
- Difficulty in distinguishing sounds, particularly in noisy environments.
- A sense of distortion in music or speech, which can lead to frustration and communication challenges.
- Variability in sound perception, where certain frequencies may be heard differently than others.

Causes

Diplacusis can arise from various underlying conditions, including:
- Hearing Loss: Sensorineural hearing loss, particularly affecting the inner ear, can lead to diplacusis.
- Ear Infections: Infections that affect the middle or inner ear may disrupt normal auditory processing.
- Ototoxic Medications: Certain medications can damage the auditory system, leading to altered sound perception.
