Breast reconstruction for premalignant and malignant disease--an update.

New concepts in the control of breast cancer and improvements in plastic surgery techniques have facilitated subsequent breast reconstruction. In a six-year period 72 breast reconstructions were carried out in 57 women after surgical treatment for premalignant or malignant breast disease and, in some cases, radiation therapy. The average age of the patients was 48 years and the average interval between the primary cancer operation and breast reconstruction was 42 months. Our experience in these cases has been free of serious complications.

Submuscular breast reconstruction--indications and techniques.

We review the care and treatment of 93 patients who underwent submuscular breast reconstruction in our service between 1975 and 1980. The indications and clinical situations in which submuscular reconstruction has been useful include: following simple mastectomy; following modified radical mastectomy; following subcutaneous mastectomy (immediate or delayed reconstruction); in standard augmentation mammaplasty in selected patients; and with unusual, unsatisfactory, or dangerous preexisting breast conditions. Unusual indications include unsatisfactory subcutaneous placement with capsule formation after subcutaneous mastectomy; use of unsatisfactory or dangerous implants such as Ivalon and Etheron; and replacement of the old-fashioned Cronin gel implants with fixation patches. Submuscular placement has also been used to advantage in patients with excessively scarred, tenuous skin. Technical modifications in the submuscular implantation technique are detailed. We have used subserratus-subpectoral placement in most instances. Technical tips to keep the implant in a low position by division of the serratus attachments and limitations of upward dissection are detailed. Clinical studies on the upward migration of implants and pressures developed under the serratus and pectoralis muscles as measured by manometer are also detailed.

Results of argon laser exposure of capillary hemangiomas of infancy--preliminary report.

Argon laser photocoagulation of capillary hemangiomas of infancy ("strawberry marks") has been described in three cases. Treatment in the first case was necessitated by repeated alarming hemorrhage. The second case was treated totally and resulted in immediate induced resolution of the hemangioma, which preceded (by 9 months) the spontaneous involution of an untreated control comparison area and resulted in virtually complete blanching without secondary deformity. The third case demonstrated the laser's ability to stop rapid growth immediately. Spontaneous involution then ensued naturally and was complete 12 months later. It should be emphasized that the argon laser is not recommended for the routine treatment of a normally spontaneously involuting hemangioma. Each case must be examined and the usual indications for intervention should be present. The argon laser has demonstrated the ability to coagulate vascular lesions such as port wine hemangiomas and telangiectasias and can be expected to have a similar favorable effect on the aggressive, rapidly expanding juvenile hemangioma, although further clinical documentation clearly remains to be demonstrated.

Progress report on extended clinical use of the argon laser for cutaneous lesions.

Since 1970 a variety of cutaneous lesions have been successfully treated with the argon laser and the histopathology carefully studied at the Palo Alto Medical Clinic. Patients with port wine hemangiomas, capillary/cavernous hemangiomas, and telangiectasia have achieved successful resolution in some cases, and subtotal blanching in other cases, with a low incidence of scarring or other complications. Recently, decorative tattoos as well as a variety of miscellaneous pigmented or vascular skin lesions, such as seborrheic keratoses, pyogenic granulomas, and senile angiomas, have also been successfully treated with the argon laser. Total clinical experience is updated in this report.

"I-P flexor lag" after thumb flexor reconstruction---causes and solution.

A small but significant percentage of thumbs fail to regain complete range of motion after reconstructive procedures designed to replace lost function of the flexor pollicis longus tendon. A characteristic but little noted posture and attitude of metacarpophalangeal flexion with loss of interphalangeal motion and metacarpophalangeal stabilisation with restoration of interphalangeal motion is described. ("I-P flexion lag"---I.P.F.L.) Clinical caused include shortening of the muscletendon unit, loss of pulleys with bowstringing, adhesions and hypermobile joints.

Subungual osteochondroma. Differential diagnosis and treatment.

Subungual osteochondroma, a rare disorder of the fingers and toes, occurred in five patients. Clinical features of the condition include nail deformation, history of long, slow growth, and characteristic radiologic features. Surgery is directed toward total tumor resection with preservation of the nailbed to achieve normal nail growth. Differential diagnosis included bony, cartilagionous, and soft tissue tumors as well as cystic lesions. Malignant tumor should be suspected by not confused with this benign disorder. Roentgenologic examination is indicated in the differential clinical diagnosis of any subungual mass.

Argon laser treatment of decorative tattoos.

The argon laser shows promise as an effective clinical method for the treatment of tattoos. Although clinical follow-up has been limited to 3 years and less in a series of 30 patients, the preliminary results are sufficiently optimistic to recommend further clinical use of the argon laser for such treatment.

Temporomandibular joint disease: results of a ten-year study.

Ninety patients with clinically documented temporomandibular joint disease were followed for ten years. Sixty-four of these patients were treated by conservative means alone, and over 90% responded with complete relief of symptoms. Conservative therapy consisted primarily of jaw rest, with adjunctive use of heat, analgesics, and antiinflammatory agents.

Custom-fabricated silicone implants for contour restoration.

A 15-year review is made of contour restoration by custom silicone inlay technique. Eighty-three patients have undergone surgery since 1962. The indications, preparation of moulage and implant, surgical technique, and care of complications are described. The custom silicone technque has proved successful, precise, and relatively free of complications. Tolerance of uncomplicated implants has been permanent.

Post-pneumonectomy syndrome. Surgical correction using Silastic implants.

A post-right pneumonectomy syndrome is described which manifests symptoms of exertional dyspnea and inspiratory stridor on rapid inspiration. These symptoms were associated with marked rightward and posterior deviation of the trachea, over-distention of the left lung with its herniation into the right side of the chest and kinking of the left lower lobe bronchus. At the time of surgery, the tracheal deviation, lung herniation and the kink in the left lower lobe bronchus were immediately corrected by releasing the adhesions between the malpositioned structures and the right chest wall. To maintain the corrected positions, Silastic implants totalling a volume of 990 ml were placed into the space created in the right chest. Following surgery, exertional dyspnea was present with only extraordinary activity, and inspiratory stridor was eliminated. The patient remains asymptomatic three years following surgical correction, and is able to carry on a normal and productive life. We conclude that a syndrome associated with marked exertional dyspnea and inspiratory stridor might develop in situations of marked tracheal shift and overdistention of the remaining lung following right pneumonectomy.

Extended clinical use of the argon laser for cutaneous lesions.

A safe, easy, and effective outpatient modality for the treatment of various cutaneous lesions such as hemangiomas and decorative tattoos has long been sought. The argon laser has proved satisfactory for such treatment of port-wine hemangiomas, capillary/cavernous hemangiomas, telangiectasia, and decorative tattoos as well as a variety of cutaneous pigmented lesions. The intense laser light is attracted and absorbed by pigmented skin lesions producing heat that selectively destroys the intradermal pathologic condition and spares overlying skin. Hemangiomas and tattoos have undergone satisfactory subtotal blanching in the majority of cases with a low incidence of hypertrophic scarring. Thus, the argon laser has proved useful in the outpatient treatment of a variety of pigmented cutaneous lesions.

Argon laser treatment of cutaneous vascular abnormalities: progress report.

One hundred six cutaneous vascular abnormalities were treated over a 3-year period by the argon laser. Absorption of light energy causes heat coagulation of the hemangioma with sparing of the overlying skin and secondary skin appendages. Patients with port wine hemangiomas, capillary/cavernous hemangiomas, and telangiectasia showed good response to argon laser treatment. Superficial varicosities of the lower extremity proved to be relatively insensitive to laser treatment. The argon laser shows promise as an effective clinical tool in the treatment of hemangiomas; however, further clinical and laboratory investigation will be necessary to establish the laser as the modality of choice in the treatment of such lesions.

"De-epithelization" and dermal pedicles.

Biopsy specimens from 38 "de-epithelized" dermal pedicles were examined microscopically. There was considerable variation in the depth of the plane among surgeons, procedures, and even between specimens from two sides of a bilateral procedure done by the same surgeon. Usually, the "de-epithelization" removed all the epidermis plus the upper layer of dermis containing the pilosebaceous apparatus. The significance of this finding as related to the future development of epidermal inclusion cysts is uncertain. Also, it brings into question the importance of "the dermal plexus circulation," which many have thought to be critical for viability of the nipple.
