Dermatologic diseases of the external ear

Area of Science:

• Dermatology
• Otorhinolaryngology
• Plastic Surgery

Background:

• The external ear, comprising the auricle and auditory canal, is prone to environmental damage and skin lesions due to its exposed location.
• The skin of the external ear contains glands and hair follicles, making it susceptible to ultraviolet radiation, trauma, and subsequent neoplastic changes.
• Dermatologic conditions of the ear are frequently encountered across multiple medical specialties, necessitating a comprehensive understanding.

Purpose of the Study:

• To provide a comprehensive review of dermatologic diseases affecting the external ear.
• To update current diagnostic approaches for external ear lesions.
• To summarize contemporary treatment modalities for these conditions.

Main Methods:

• Literature review of dermatologic conditions of the external ear.
• Synthesis of diagnostic criteria for various ear lesions.
• Compilation of current treatment guidelines.

Main Results:

• External ear lesions are categorized into infectious, tumoral, and noninfectious inflammatory types.
• The auricle's exposed position increases vulnerability to sun damage and skin cancers.
• Accurate diagnosis is crucial for effective management of diverse ear conditions.

Conclusions:

• Effective management of external ear dermatoses requires interdisciplinary collaboration.
• Understanding the unique anatomy and environmental exposures of the ear aids in diagnosis.
• This review provides updated information for clinicians managing ear skin conditions.
