摘要:

Cadaver studies and clinical evidence are presented to suggest that medial wall fractures are often concomitant with orbital floor fractures. The medial wall fractures are located in the ethmoid bone midway between the medial canthus and the lesser wing of the sphenoid. These fractures may be the etiology of late enophthalmus. The discrepancy between the high frequency of occurrence of medial wall fractures in this study and the rarity of clinical diagnosis derives from the limitations of standard radiography. Computed tomography (CT scan) is useful in delineating these fractures. The operative approach is through an incision above the medial canthus. Surgical treatment includes reduction of the herniated periorbital fat and coverage of the defect with autogenous, homologous, or alloplastic materials.

摘要:

Using three different instruments, cryolesions were made in the skin of experimental animals (pigs) and the extent of necrosis was determined after one week. The most efficient device was a probe using liquid nitrogen; the amount of tissue killed varied directly with contact time. With all the instruments, a freeze of three minutes consistently led to full-thickness necrosis of the skin. The freeze-thaw-refreeze technique did not produce as much necrosis as a single continuous freeze of the same duration. Cryosurgery was used on 65 benign skin tumors in patients. Pain was minimal and the cosmetic results were excellent. The only difficulty with the method was that it occasionally failed to kill the lesion. For that reason, at present cryosurgery is recommended only for benign lesions. If one suspects that a tumor might be cancerous, it should be biopsied before freezing. If it pr'oves to be malignant, further treatment (excisional or x-ray) should be considered strongly.

摘要:

Ankylosis of the temporalis-coronoid complex is a clinical entity. The etiology is usually direct trauma to the temporalis muscle or coronoid process of the mandible. It is difficult to differentiate diagnostically from ankylosis of the adjacent temporomandibular joint, and should always be considered in the differential diagnosis of inability to open the mouth. The treatment is always surgical and the intraoral approach is favored. The cure rate with this modality of therapy has been gratifying.

摘要:

Three patients with histological evidence of incompletely removed basal cell carcinoma underwent reexcision; no residual tumor was found. Other reports of this phenomenon are discussed and some speculative explanations are offered.

摘要:

This paper describes a helpful operation for revision of the difficult ileal stoma for urinary diversion. By using the standard technique of panniculectomy or abdominal lipectomy, the ileal loop can be left in the same position on the abdominal wall and healthy, viable tissue can be mobilized and repositioned to enable the urological surgeon to perform the cutaneous portion of the procedurt again and to refashion the ileal loop. This saves the patient an operation of greater magnitude and risk.

摘要:

The inverted nipple has been attributed to hypodevelopment of both nipple and areolomamillary musculature. A number of procedures have been devised to correct this deformity for the purposes of nursing and also for cosmesis. Excision of the entire areola, myotomy of areolomamillary bundles, and partial areolar excision in apposing quadrant triangles have all been used.An operative technique has been designed reflecting some of the older methods and an innovation utilizing areolar V-Y plasties and purse-string sutures to the nipple base for support. This method avoids excision and consequent extensive scarring of the areola. This procedure has been found to have satisfactory functional and cosmetic results in clinical trials to date.

摘要:

Rhinophyma is classically a benign tumor of unknown etiology and pathogenesis. Once fully developed, it requires surgical treatment; its management has invited controversy for more than a century. We favor electrosurgical sculpturing, removal of the burned tissue by abrasion, treatment of the entire nasal cover as a unit, and the utilization of biological dressings to promote reepithelization. The cosmetic results have been gratifying.
