Sixteen patients with 18 telangiectatic lesions have been treated by means of an argon laser over a 7-year period. The physics and medical uses of the laser are reviewed and the pathology of the laser wound is discussed. Seventeen of 18 lesions responded satisfactorily and suggest that the argon laser is a simple, effective clinical tool for the treatment of cutaneous vascular lesions.
Rheumatoid disease, as it affects the hand, is a disease of the synovium lining the joints and sheaths of the tendon. The proliferating synovium destroys the articular surfaces of the joint, interferes with the gliding mechanism of the tendons and weakens the supporting ligaments of the joints. The degree and variety of deformities is multifold. Treatment of the rheumatoid hand is aimed at conservation and restoration of hand function, as well as prevention of future deformities. Rheumatologists, physical therapists and hand surgeons carry out important functions in the well-planned, integrated regimen. Surgical treatment of the rheumatoid hand deformity may alleviate pain, lessen deformity and improve function in selected cases. It should be integrated in the general medical management of a patient. Treatment of tendon ruptures includes tenorrhaphy, tendon grafting and arthrodesis in the case of mallet finger deformity. The wrist joint is improved by synovectomy and carpal tunnel release is accomplished by median nerve decompression. Metacarpal phalangeal joint deformities may be treated by synovectomy or silastic joint replacement when there is destruction of the articular joint surface, severe subluxation, or persistent painful motion.
Thirty selected patients with simple zygoma fractures over a 15-year period have been treated by elevation and reduction with the use of a zymgomatic elevator from an intraoral upper buccal sulcus approach. No patient suffered a recurrence of the fracture of deformity or required an open reduction. This little publicized procedure is easy, fast, and effective in carefully chosen cases of zygoma and zygomatic arch fractures in the first 72-96 hours postinjury. It should be considered by the surgeon along with the more complex procedures.

Eight cases of extensive oromandibular resections have been reconstructed by the use of deltopectoral shoulder flaps with a segment denuded for deep placement. The operative technique is described, and the various uses of this flap are outlined. This technique has allowed us to extend the versatility of the deltopectoral flap, and to avoid the occurrence of the often annoying and occasionally dangerous orocutaneous fistula.
Our experience utilizing a new design Lash-Maser silicone implant in the surgical management of impotence has been detailed. The present series includes twenty-five patients, twenty-three of whom achieved satisfactory intercourse without problems or complications. The implant's simplicity of design, function, and surgical implantation is appealing.
A technique is described using the epithelium over a keloid as a graft after excision of the keloid. Advantages of this procedure are availability of skin and avoidance of the danger of keloid formation in a distant donor site. Results in a series of five patients followed for five years were satisfactory in three.
Twenty-two patients with cutaneous vascular malformations were treated with an argon laser. Promising results were obtained in patients with port-wine stains, hemangiomas, telangiectasia and varicose veins. The argon laser shows promise as an effective clinical tool in the treatment of all such cutaneous vascular abnormalities. However, further study of clinical as well as laboratory data is necessary over a long period of time before this modality can be definitely recommended as the treatment of choice for vascular deformities of the skin.

The silicone inlay method of prefabricating subcutaneous and bony implants for congenital and acquired defects of the maxillofacial area was used in 25 cases. Heat vulcanized Silastic 372 or 373 was used, and seems to be satisfactory. The method is presented as a useful addition to the surgical restoration of subcutaneous and bony defects, particularly complex contours of the periorbital area when autogenous tissue is unavailable. Complications seem to be less common when the implant is immobile and secured to bone. The method is evolving, and modifications can and should be made in the technique.
In ten patients breast reconstruction was done after surgical treatment for a premalignant or malignant breast disease. In six of these, prophylactic subcutaneous mastectomy and implant reconstruction were carried out, and in the remaining four reconstruction was done after simple or modified radical mastectomy. It is suggested that these procedures should be considered by those physicians and surgeons who undertake evaluation and treatment of breast disease in women. Breast reconstruction should be considered and offered to patients who suffer from the severe personal and emotional trauma attendant to surgical operation for breast disease.
A case of room-temperature vulcanizing (RTV) silicone injection of the hand is presented, and principles of management of high-pressure hand injuries are outlined. Early debridement and decompression are urgent in the acute stage of injury. Intermediate stages require adequate coverage and mobilization, and late stages involve reconstructive procedures. As in all high-pressure hand injuries, safety measures and prevention at the industrial level are very important.

A summary of the pathophysiology and clinical use of the argon laser in the treatment of cutaneous lesions is presented. The nonionizing blue-green argon laser light is absorbed by pigment, is converted to heat, and selectively destroys specific cutaneous lesions with sparing of adjacent dermal appendages and healing of the laser wound with minimal scarring. Vascular lesions (port wine hemangioma, capillary-cavernous hemangioma, telangiectasia), inflammatory lesions (pyogenic granuloma), nevoid lesions, tattoo lesions, and a variety of miscellaneous lesions have been successfully treated.
