Otitis externa. Management in the primary care office

Area of Science:

• Otolaryngology
• Infectious Diseases

Background:

• Otitis externa is a common ear infection, frequently caused by Pseudomonas aeruginosa.
• Key symptoms include ear pain, discharge, and ear canal swelling.
• Granulation tissue is a concerning sign, potentially indicating severe necrotizing otitis externa or cancer.

Purpose of the Study:

• To highlight the importance of recognizing signs of otitis externa.
• To emphasize the role of primary care physicians in managing ear infections.
• To stress the need for timely referral to specialists for complex cases.

Main Methods:

• Review of clinical manifestations of otitis externa.
• Discussion of common causative agents, particularly Pseudomonas aeruginosa.
• Emphasis on diagnostic signs such as granulation tissue.

Main Results:

• Pseudomonas aeruginosa is the most frequent pathogen in otitis externa.
• Pain, discharge, and edema are characteristic symptoms.
• Granulation tissue signifies a potentially serious underlying condition.

Conclusions:

• Primary care physicians must be proficient in ear cleaning and topical medication use for otitis externa.
• Prompt referral to an otolaryngologist is essential when suspecting severe underlying causes.
• Awareness of ominous signs like granulation tissue is critical for patient outcomes.
