A case report of otoendoscopic radiofrequency resection of squamous cell carcinoma of the external auditory canal.

Squamous cell carcinoma is the most common pathological type of external and middle ear malignancy. Squamous cell carcinoma of the external auditory canal and middle ear is closely associated with long-term chronic inflammatory irritation. The patient was admitted with a major complaint of a "stuffy feeling in the left ear for more than three months." The results of the otoendoscopic examination were as follows: The left external auditory canal was filled with a granuloma-shaped mass with an unsmooth surface that showed obvious oozing of blood. The tympanic membrane was not visible. After the completion of the relevant examinations, radiofrequency resection of the external auditory canal mass was performed under otoendoscopy and the wound healed well with postoperative dressing changes. Pathological results revealed a well-differentiated keratinizing cutaneous squamous cell carcinoma and there was no recurrence throughout the next 5 years after the operation. Proper preoperative evaluation and the correct selection of surgical approaches can be of great importance. The primary complication of ear squamous cell carcinoma was local recurrence with a low incidence of metastasis. Early and complete resection was determined to be the optimal course of treatment.
