The totem pole rib graft reconstruction of the nose.

The totem pole rib bone graft for nasal reconstruction is presented as an effective way to prepare the donor bone for the correction of saddle-nose deformity. The article's title emanates from the fact that when the sculpturing of the rib is completed it has the appearance of a totem pole before the separate parts are disarticulated for insertion into the nose. The use of this technique permits an accurate, detailed sculpturing of the component parts of the subsequent reconstruction, permitting correction of each feature of the saddle-nose deformity. If these bony segments were dissected or sculptured separately, the smallness of each part would make it very difficult to carve the precise definition needed for a reconstruction that would give structural support and at the same time afford an aesthetically pleasing result. The rationale of the technique and representative cases are presented.

The conchal flap: an adjunct in otoplasty.

When the protruding ear is caused in whole or in part by an enlarged or abnormally angulated concha, the conchal set-back is a recognized technique in corrective surgery. The authors describe a modification of this procedure in which a posterior flap of cartilage, based laterally adjacent to the antihelix, is elevated and sutured to the mastoid process. The maneuver serves to bring the concha closer to the scalp and thus reduces the protrusion. The residual deformity in the conchal bowl, resulting from the development of this cartilage flap, is negligible. The authors stress the need for correct analysis of the original deformity and usually employ this maneuver in conjunction with a suture technique for creating or accentuating a poorly defined antihelix.

Recognition and treatment of recurrent basal cell carcinoma.

The recognition and treatment of recurrent basal cell cancer presents a diagnostic as well as a therapeutic problem. While recurrences are often masked by previous surgical efforts, there are definite clinical features that warrant suspicion and subsequent biopsy. Adequate therapy can come only with accurate recognition and aggressive treatment using microscopical control.

Secondary island composite flap: an experimental study in ear reconstruction.

An experimental study is presented which demonstrates that a large composite graft of cartilage and skin can survive with an overlying skin flap. The grafts were transferred without loss of configuration when the composite tissue was placed on a bed of vascular tissue. The presence of a skin flap over the graft appears to assist in providing an environment conducive to survival while neovascularization is occurring. This is the first stage in developing a technique of ear reconstruction in which the overlying skin is not used and the cartilage will retain its shape with subsequent transfer.

A modified gluteus maximus musculocutaneous free flap based on the inferior gluteal vessels.

A single case is reported of a large posterior calf defect, involving skin, subcutaneous tissue, and underlying muscle, in which contour is restored employing an inferior half of the gluteus maximus musculature and overlying skin as a free flap. In this patient a bulk of tissue was moved using microvascular surgical techniques while maintaining minimal donor site deformity.

The perioperative management of the patient with pressure sores.

The occurrence of pressure sores is a major obstacle to the long-term rehabilitation of the spinal cord--injured patient. To achieve the best functional result with the most efficient use of resources, a comprehensive treatment plan is needed. In our twenty-five-year experience we have evolved guidelines for the perioperative management of the spinal cord-injured patient with pressure sores. Through a team approach such as that used at TIRR, the spinal cord-injured patient with a decubitus ulcer can be treated and rehabilitated. Our aim is to decrease morbidity, achieve better functional outcome, and efficiently utilize public and private resources to rehabilitate such patients.

V-Y advancement of a subcutaneous pedicle in vermilion lip reconstruction.

We present three patients with lip cancer in whom the classic wedge excision would have resulted in an inordinate loss of tissue and possible compromise in shape and function. Without sacrificing the primary principle of adequately removing the cancer, the authors were able to excise the lesion and reconstruct the defect by means of a subcutaneous pedicle that might otherwise have been discarded with the usual wedge resection. There is a slight tendency for the healed skin flap to exhibit trapdoor scarring; however, in the older age group, in whom this technique has its greatest applicability, this has not been a permanent problem. This one-stage method of closing lip defects using subcutaneous pedicle flaps has the additional advantages of easy execution and minimal morbidity.

Evolution of the clinically negative neck.

A retrospective study was done of 602 patients with primary squamous cell carcinoma of the upper aerodigestive tract and a clinically negative neck (No) seen at the University of Illinois Hospital between 1960-1975. There was no uniform policy as to the treatment of No neck during this period; therefore in many of the patients, cervical lymph nodes were treated with elective neck dissection and others were followed until they became positive clinically. It was this difference which formed the basis for this study. All the patients were treated surgically; the patients were placed into two groups depending on whether they had radical neck dissection at the same time as resection of the primary. Group 1 consisted of 149 patients and had surgery for the primary only. The 253 patients of group 2 had surgery for the primary and also had a neck dissection. Both groups were analyzed for recurrences in the cervical region. In group 1, 12.9% of the patients developed either ipsilateral or contralateral metastases. Of the group 2 patients, 22% developed palpable nodal disease. The evolution of palpable nodal disease was analyzed by primary site, T-stage, and according to whether the tumor at the primary was controlled. Only 3% of the patients developed lymph nodes when the primary was controlled. The pathology reports of the neck specimens were studied to determine the relationship between a) positive node histology and b) number of nodes positive to the recurrence rate in the neck. Our results showed a 23% failure rate for the histologically positive group and a 21% failure rate for the negative group. The number of positive nodes did not seem to affect the recurrence rate.
