OBJECTIVE
To provide family physicians with a practical evidence-based approach to management of otitis externa.
SOURCES OF INFORMATION
The approach described is based on MEDLINE and PubMed literature published between 1993 and 2023.
MAIN MESSAGE
Otitis externa is diffuse inflammation of the external auditory canal and typically occurs from moisture exposure and trauma. Management focuses on eliminating infection, pain management, education, and preventing recurrence. The primary treatment of uncomplicated otitis externa is topical. Complicated presentations may require additional systemic therapy.
CONCLUSION
History taking and physical examination can help differentiate among acute, chronic, and necrotizing otitis externa. At-risk populations, typically those who are immunosuppressed, are more likely to develop necrotizing otitis externa and should be carefully monitored.
目的
为家庭医生提供一种实用的基于循证的方法来管理外耳炎。
信息来源
所描述的方法基于 MEDLINE 和 PubMed 文献，发表时间为 1993 年至 2023 年。
主要信息
外耳炎是外耳道的弥漫性炎症，通常由水分暴露和创伤引起。管理重点是消除感染、缓解疼痛、教育和预防复发。未经处理的外耳炎的主要治疗方法是局部治疗。复杂的表现可能需要额外的全身治疗。
结论
病史采集和体格检查有助于区分急性、慢性和坏死性外耳炎。高危人群，通常是那些免疫抑制的人，更容易发生坏死性外耳炎，应密切监测。
