[Squamous cell carcinoma of the external ear. A carcinoma of old age which requires individualized therapy planning].
METHODS
Data for all patients with ear malignancies being operated in our department between August 1988 and March 2001 were retrospectively analyzed for tumor localisation, stage, biometric data, anesthesiological risk factors, therapy and recurrence of the disease.


RESULTS
Thirty of 79 patients (29 male, one female; average age 77.2 years, range 54-99 years) with cutaneous malignancies of the external ear were diagnosed as SCC ( n=32 SCC). A total of 17 SCC were smaller than 2 cm, 12 were between 2-5 cm, and three were larger than 5 cm. Only two patients had regional nodal disease, none had distant metastases. The anesthesiological risk was estimated according to the recommendations of the American Society of Anesthesiologists (ASA); 16/30 patients were classified as group 3 or 4, having severe general disease with a decrease in vitality or even vital risks. A total of 24 SSC were primarily operated under local anesthesia. Depending on histology, localisation and size of the SCC local excision, partial or total removal of the auricle was performed. In the remaining 8/32 cases, the primary intervention was performed under general anesthesia, mostly in combination with an ipsilateral neck dissection and a superficial parotidectomy. In 8/32 cases, the SCC had to be re-operated after primary R1 resection. Altogether, eight patients received radiotherapy. In 5/32 cases there was a recurrence of the disease. The average follow-up period of the 13 patients who are still alive is 50 months (17-113). One patient died as a result of the metastasized SCC and 16 patients died due to other diseases.


CONCLUSIONS
Considering the high age and the age-associated general diseases of the patients with SCC of the auricle, differentiation between a radical concept of therapy and its risks and possible therapy-related damage is important. Therefore, individual concepts such as partial removal of the pinna without neck dissection and parotidectomy for the N(0) stage are justified if relevant anesthesiological risk factors have to be taken into account.
