The purpose of this study of 81 patients with basal cell carcinoma (BCC) of the nose was to present the oncological and cosmetic results of surgical treatment and compare these results with those of other possible treatments. METHODS We report a series of 81 cases of histologically proven BCC of the nose located chiefly on the alae nasi and on the lower end of this organ; 42 p. 100 of the tumors had previously been treated and had recurred. The patients' mean age was 63 years, and the shortest follow-up was 3 years. Excision of the tumor under simple or reinforced local anaesthesia was complete in 88 p. 100 of the cases, incomplete or borderline in 12 p. 100 and systematically repeated. Extemporaneous histological examination was performed in 18 p. 100 of the cases. The operative lesion was repaired with a graft or a flap. There was no postsurgical treatment. RESULTS The recurrence rate was 4 p. 100 with a minimum follow-up of 3 years. The cosmetic result was good in 78 p. 100 of the patients. CONCLUSIONS Numerous treatments have been used against BCC of the nose, the results, advantages and disadvantages of each of these treatments are given below: 1. Cryosurgery. The problem with this method is that it is relatively difficult to perform and requires reliable operators. The cure rate is similar to that of other treatments. 2. Chemotherapy is not frequently used. 3. Electrocoagulation. Contrary to the conventional excision, this method precludes all histological controls, and the common idea of good oncological results is now being revised. 4. Radiotherapy. The recurrence rate varies from 7 to 11.8 p. 100 with fair cosmetic results. It requires numerous sessions, cannot be repeated in case of recurrence and complicates the surgical treatment. In addition, there is a long-term risk of radiodystrophy. 5. Curietherapy by local implantation of 192Iridium has a recurrence rate of 2.5 to 7 p. 100. This treatment requires hospitalization and is costly. It is indicated in cases of complex surgery, difficult conventional radiotherapy and above all, sclerodermatous BCC. 6. Surgery has a recurrence rate which varies from 3.7 to 12.6 p. 100. Recurrences are due to insufficient excision, and this underlines the value of histological control which can be done only at surgery. It is a rapid and ambulatory treatment, usually performed under local anaesthesia. The cosmetic result is good (85 to 90 p. 100) and the patients must be made aware of this preoperatively with some degree of reliability, depending on age, location, size of BCC and on the surgical technique utilized. CONCLUSIONS Surgical treatment of nasal BCC is safe, effective and rapid, with good oncological and cosmetic results, and it has many advantages over the other treatments.
