Clinical Causes: Chronic ear infections or otitis externa Previous trauma or injury to the ear canal, such as lacerations or burns Prolonged use of ear medications or foreign objects inserted into the ear Repeated surgical procedures or interventions Chronic skin conditions affecting the ear canal, such as eczema or psoriasis Benign or malignant growths or tumors within the ear canal Exposure to environmental irritants or chemicals

Key Symptoms: Reduced or muffled hearing in both ears Feeling of fullness or pressure in the ears Discomfort or itching in the ear canal Possible ear pain or tenderness Presence of a visible narrowing or blockage during examination Occasional ear discharge if infection is present Difficulty with balance or dizziness in some cases

Diagnosis Path: Diagnosis of acquired stenosis of the external ear canal involves a comprehensive clinical examination by an ear specialist. The physician will examine the ear with an otoscope to visualize the narrowing or blockage. Additional tests may include audiometry to assess hearing levels and imaging studies, such as CT scans, if underlying structural abnormalities or growths are suspected. A detailed medical history focused on prior ear infections, injuries, or surgeries is also essential to identify contributing factors.

Treatment Protocols: Management of bilateral acquired stenosis typically focuses on relieving symptoms and preventing further complications. Treatment options include: - *Earing cleaning and removal of debris*: To keep the ear canal as clear as possible. - *Topical medications*: Such as corticosteroids or antibiotics if inflammation or infection is present. - *Surgical intervention*: Procedures like canalplasty can widen the ear canal, especially in severe cases where the narrowing significantly impairs hearing or causes discomfort. - *Addressing underlying causes*: Managing skin conditions, avoiding irritants, and treating infections are critical components. - *Hearing aids or assistive listening devices*: Might be recommended if hearing impairment persists. Regular follow-up with an ear specialist is essential to monitor the condition and prevent recurrence.
