Auricular wedge resection and reconstruction.
Various techniques have been described in the literature for auricular reconstruction after resection of both benign and malignant tumors of the auricle. Since 1981, I have performed simple wedge resections of the auricle as treatment for both basal and squamous cell carcinomas. A 4-mm margin on the former lesions and a 6-mm margin on the latter lesions have been used routinely. Thirty patients so treated were studied. The follow-up period for most of the patients was a minimum of one year, and only 1 patient had a recurrent lesion, which was resected without complication. The size of the lesions ranged from 4 mm to 3 cm. The majority of the lesions were either basal or squamous cell carcinomas (other lesions included melanomas, fibrous histiocytomas, and chondrodermatitis nodularis chronica helices), and multiple frozen sections of the margins resected were carefully examined. The technique of reconstruction using polyglactin 910 sutures on the cartilage and a molded otoplasty dressing contributed to a good cosmetic result for all patients.

T-lymphocytes and survival of head and neck squamous cell carcinoma.
The thymus-dependent lymphocytes (T cells) were enumerated in the peripheral circulation of 38 patients with histologically demonstrated squamous cell carcinoma of the head and neck. We have previously shown that this "total" T-cell count correlates well with degree of tumor involvement. A lower percentage of T cells were shown in patients with more advanced malignant neoplasms. Here we present follow-up data on these patients to evaluate the efficiency of the T-cell test in determining survival prognoses. We found no evidence that results of this test can extend prognostic abilities above those based on clinical staging. The survival data from six patients treated with a chemoimmunotherapy regimen of BCG vaccine, methotrexate sodium, and isoniazid did not demonstrate an increased survival time compared to patients at similar clinical stages who were treated by conventional use of surgery and irradiation.

Investigation of the mesotympanum's reaction to silastic and gelatin film.
The section of the cat's mesotympanum, denuded of mucosa, to Silastic and gelatin film was studied and compared with the contralateral control ear, which was also denuded of mucosa. The ears were studied by horizontal pathological sections taken one, two, four, and six months post-lympanotomy and insertion of either gelatin film or Silastic. The Silastic, gelatin film and control ears were compared for inflammatory reaction, amount of fibrosis, and the quality and quantity of mucosal regeneration. The inflammatory reaction was increased in the ears with Silastic compared with their corresponding control ears or to the ears with gelatin film. The amount of fibrosis and the quality and quantity of mucosal regeneration was essentially the same in the Silastic, gelatin film, and control ears. This study shows that both substances are well tolerated in the middle ear and that neither substance stimulated or inhibited the regrowth of mucosa or fibrous tissue when compared with the control.

M-plasty techniques.
Conventional closure of surgical defects in skin may cause unsightly protrusions (dog ears). Fusiform excisions with angles of 30 degrees or less reduce protrusion but may require excision of larger volumes and lengths of healthy skin and subcutaneous tissue than may be desirable. M-plasties reduce these requirements while still allowing use of 30 degrees angles at maximum. Applications and technical details are described and illustrated.
