Augmentation of surviving flap area by intraarterial vasodilators administered through implantable pumps.

Using the implantable Infusaid Model 300 pump, several vasodilators (prostaglandin E1, isoxsuprine, bradykinin, trimethaphan, and reserpine) were infused intraarterially into an abdominal island flap in the rabbit. All produced a large increase in flap surviving area over saline controls at forty-eight hours, measuring as high as a 2.8-fold increase in random portions of the flap with prostaglandin E1. The agents possessed differing modes of action but had the common property of vasodilatation. The results raise questions concerning the possible physiological role of endogenous prostaglandins in the surgical delay phenomenon. The Infusaid pump was a valuable tool in the study and was well tolerated by the animals.

The nonmetropolitan plastic surgeon.

A questionnaire survey was conducted of 54 board-eligible or board-certified plastic surgeons practicing outside urban or suburban areas. Marketplace forces were determined to have been important in the choice of nonmetropolitan practice locations. The practitioners surveyed tended to participate in a broad spectrum of plastic surgical practice. On the whole, the surgeons reported themselves busy professionally and contented personally. A characteristic pattern of problems often accompanied the practice style.

History and plastic surgery: systems of recovering our past.

Plastic surgeons have taken uncommon interest in their past. Systematized approaches toward the collection of historical information have characterized the specialty. Plastic surgery is the only discipline to have compiled a complete bibliography of its world's literature. The Archives maintains an ongoing program of acquisition of the oral, written, and personal memorabilia of the notable leaders and events of plastic surgery.

Woodsplitter injuries of the hand.

The hydraulic woodsplitter is a new labor-saving tool for woodstove users. A new spectrum of hand injury has been observed in association with its use. Twenty-three such injuries are reviewed. Among these were nine digit amputations, four of which were successfully replanted. There was a surprising preponderance of central digit injury, with border digit sparing due to the dominant role of the central digits in power grip of the log. Both human carelessness and faulty design features were instrumental in the production of injury.

Soft-tissue reconstruction of below-knee defects.

The stable closure of an indolent wound below the knee may require the placement of well vascularized flap tissue. Recent advancements in axial and microvascular flap transfer have nearly obviated the use of the cumbersome traditional cross-leg flap. Thirty-two flaps in 25 below-knee defects illustrate a variety of surgical options. Closed stable wounds were achieved in 24 of the 25 defects, and bony union was accomplished in 11 of 12 unhealed fractures.

Split pectoralis major myocutaneous flap.

A variation of the pectoralis major myocutaneous flap in head and neck reconstruction is presented. The defect to be covered was a large, intraoral, U-shaped defect extending from the left tonsillar region around the alveolar ridge and floor of mouth to the right soft palate and buccal mucosa. Nearly the entire tongue was intact, and a 4 cm left mandibular segmental defect existed. A single left pectoralis major myocutaneous island flap was split longitudinally to resurface the defect. Implications of vertical splitting of a myocutaneous flap are discussed with respect to blood supply and limits.

Cricothyroidostomy in head and neck surgery.

Cricothyroidostomy is a procedure whose time has come back. Having been quickly and widely readopted by thoracic surgeons in the past 4 years, it is a technique that is particularly advantageous to the head and neck surgeon for many reasons. In the absence of any compelling experience to the contrary, we foresee a diminishing role for the "standard" tracheostomy. Cricothyroidostomy appears to be a safe and effective procedure.

Massive basal cell carcinoma of the scalp: successful management by cooperation of chemosurgeon and reconstructive surgeon.

No single modality is appropriate for treatment of the huge invasive basal cell carcinoma. Mohs' chemosurgery is perhaps the most efficacious ablative method, but it must be supplemented by a reconstructive procedure in nearly all sizable lesions. A case history is presented of a patient with massive basal cell carcinoma involving the entire posterior scalp and deep tissues in which chemosurgical ablation and major staged reconstruction proceeded concurrently to a successful conclusion. The advantages of this approach are discussed.

Iodinated silicone-an antibacterial alloplastic material.

Iodine is readily miscible in silicones and will pass freely into and out of this material at highly predictable and constant rates. Iodinated silicone is thus an effective, controlled-rate delivery system for molecular iodine. This delivery system was shown to produce bacteriostatic and bactericidal effects in vitro, and at least bacteriostatic effects in vivo. Iodinated silicone produced a protective effect against the morbidity of infection in the mouse.
