ABSTRACT
OBJECTIVES: Hemangioma is a common soft tissue tumor that can be categorized mainly into cavernous, capillary, and venous subtypes. It usually develops in the head and neck and rarely in the external auditory canal (EAC).
METHODS: A systematic review of patients with capillary hemangioma of the EAC was performed. A computerized systematic search was conducte d in PubMed, Scopus, and Web of Science to extract relevant studies for a qualitative review.
RESULTS: A total of 38 patients were included in the systematic review, and half of them were men. Hearing loss was the most common presenting feature (n = 19; 50%), followed by aural fullness (n = 15; 39.4%). Cavernous hemangioma was the predominant type (n = 22, 57.8%). Endaural and transcanal surgical approaches were the most frequent, with 10 (26.3%) and 9 (23.6%) cases, respectively. Most of the patients (n = 31, 81.5%) had no recurrence.
CONCLUSIONS: Hemangioma of the EAC may not be uncommon, as health care professionals may expect. Hearing loss, aural fullness, and tinnitus are possible symptoms, but many patients remain asymptomatic. Surgical excision is the main effective management option, and complete resolution is the most prevalent outcome. Computed tomography assists in the diagnosis, but histopathological examination after resection is mandatory for the definitive diagnosis.
