Clinical Description of ICD-10 Code H68.133

Overview

ICD-10 code H68.133 refers to extrinsic cartilaginous obstruction of the Eustachian tube, specifically on a bilateral basis. This condition involves a blockage in the Eustachian tubes, which are critical for equalizing pressure in the middle ear and draining fluid. The obstruction is characterized by the presence of external factors, such as cartilage, that impede the normal function of these tubes.

Anatomy and Function of the Eustachian Tube

The Eustachian tubes are narrow passages that connect the middle ear to the nasopharynx (the upper part of the throat behind the nose). Their primary functions include:
- Pressure Regulation: They help equalize air pressure on both sides of the eardrum, which is essential for proper hearing.
- Fluid Drainage: They allow for the drainage of secretions from the middle ear, preventing fluid accumulation that can lead to infections.

Causes of Extrinsic Cartilaginous Obstruction

Extrinsic cartilaginous obstruction can arise from various factors, including:
- Congenital Anomalies: Some individuals may be born with structural abnormalities that affect the Eustachian tubes.
- Inflammation: Conditions such as allergies or chronic sinusitis can lead to inflammation and swelling, contributing to obstruction.
- Tumors or Growths: Benign or malignant growths in the vicinity of the Eustachian tubes can exert pressure and cause blockage.

Symptoms

Patients with bilateral extrinsic cartilaginous obstruction of the Eustachian tubes may experience a range of symptoms, including:
