The Children's Dental Center--a community resource to meet a community need.

Growing numbers of children of working poor families in California have limited access to dental care. This article presents a unique solution to this problem: the Children's Dental Center. The center, a nonprofit corporation, emphasizes quality multidisciplinary care, aggressive preventive dental practices, and education programs for parent and child. Through behavioral change, coupled with dental care of urgent problems, the family's immediate needs are addressed while creating a future of diminished dental need and greater self-esteem.

External rhinoplasties: indications for use.

The technique, indications and role of external rhinoplasty in nasal surgery are presented. The technique has been utilised in 563 patients with a minimum follow-up of 18 months. The external approach has been especially helpful in the severely twisted nose, secondary rhinoplasty, augmentation rhinoplasty, congenital deformities of the nose, closure of septal perforations and in the teaching and learning of rhinoplasty. In this series there were no reported complications attributable to the external approach.

Breast reconstruction after mastectomy. What are today's options?

Breast reconstruction after mastectomy has evolved rapidly in recent years because of public awareness, patient demand, and technical advances. Various methods involving tissue expansion and flap procedures with and without prostheses are currently available. Management of the opposite breast and nipple-areola reconstruction are also options. Patients need to be in good general health to have reconstructive surgery.

In vitro alterations in human fibroblast behavior secondary to silicone polymers.

The etiology of fibrous capsular contractures in patients with silicone prostheses is unclear. However, cellular responses to the silicone polymers of the prostheses have not been examined. The exposure of human dermal fibroblasts to the components of the silicone gel prosthesis results in a significant change in cellular configuration and a progressive reduction in cell proliferation as determined by total matrix protein assays and hemocytometer cell counts. Transmission electron microscopy, however, documents a twofold increase in the rough endoplasmic reticulum when cells are exposed to the silicone gel. These findings suggest significant alterations in the behavior of human fibroblast subpopulations in response to silicone polymers.

Nasal surgery complications.

This study examines the incidence of serious complications in nasal surgery and discusses the diagnosis and management of these complications. The authors review 259 consecutive cases performed between January 1, 1983, and August 31, 1988. One-hundred and ninety-five patients had septorhinoplasties, 29 had septoplasties, and 35 had rhinoplasties. Thirteen of these cases involved serious complications as follows: hemorrhage (5), perforation (4), infections (3), and pneumocephalus (1). All the patients with these serious complications had associated septal and/or turbinate surgery. The diagnosis and management of these complications will be discussed. In this small series of nasal surgery patients, the incidence of serious complications was 5.0 percent, with no fatalities reported. The higher incidence of serious complications occurred when associated septal and/or turbinate surgery was required. Awareness of these complications is essential because of the increasing number of patients presenting to plastic surgeons for nasal surgery in whom associated septal and/or turbinate surgery is necessary.

Primary skin closure in large myelomeningoceles.

Numerous reconstructive methods have been described for the soft tissue closure of large myelomeningoceles. Recent advances in techniques of soft tissue expansion provide yet another reconstructive option. Tissue expansion allows for primary closure of the defect with surrounding tissue, resulting in minimal donor site morbidity. This report illustrates the technique of tissue expansion in the closure of a large myelomeningocele.

Mending lips and closing gaps.

Operation PHILPLAST is neither original nor unique. Moreover, it is a tribute to our specialty that many plastic surgeons now unselfishly offer their skills through a multitude of programs in many foreign lands. Some believe that training and service cannot be combined. We strongly disagree. If the time-honored principles of supervision and progressive responsibility are practiced, the results, both educationally and surgically, are spectacular. When plastic surgeons offer their expertise abroad, they become effective ambassadors of good will. Such foreign policy is straightforward and difficult to misinterpret or distort. In the process of operating and teaching, a variety of gaps are closed: in lips, in education, in culture. Giving lip service, we conclude, is not only worthwhile; it is exhilarating.

Wound healing.

In acute wounds, there is no substitute for mechanical debridement and irrigation. Enzymes are useful in some chronic wounds, but antibacterial solutions are indicated only when gross contamination or frank purulence exists. Sutures will endure as the method of choice for precise wound closure. A moist environment and topical vitamin A appear to enhance epithelialization. Deficiencies of specific vitamins and minerals affect different aspects of repair, but excess levels do not accelerate healing. The biology of exuberant scars is a mystery, but management by pressure, steroids and surgery is often successful.

Treatment of full-thickness abdominal and chest wall losses with split-thickness skin grafting.

A 22-year-old man developed a large abdominal wall and sternal defect resulting from wound dehiscence. This was a sequel to two operations for gunshot wounds of the abdomen, the second one being for intraperitoneal abscess. The infected dehiscence was treated by the open method using povidoneiodine (Betadine) packs. As soon as the patient's condition permitted, split-thickness grafts were applied to the defect. One hundred percent success resulted, and convalescence of this critically ill patient was thereafter uninterrupted until discharge 31 days later. It is the authors' opinion that this method has a wider application than it is usually accredited.
