摘要:

Reconstruction of the average oral commissure electrical bum deformity yields good results when performed as a delayed procedure. Our preferred technique utilizes available vermilion for reconstruction of the lower lip by a rotation flap, and a mucosal advancement flap for reconstruction of the upper lip. Since using this procedure, we have not had a recurrent contracture requiring reoperation.

摘要:

The dermal–adipose segment of the inferior pole of the breast is usually resected during mammaplasty. However, this segment, based only on a medial or lateral pedicle, may be used as an axial flap to provide a moderate amount of tissue in reconstruction of the anterior thoracic regions.

摘要:

A laminated wound dressing was developed to deliver mafenide acetate to granulating wounds. This study, using mafenide acetate cream (11.2%) and isotope dilution of14C–labeled mafenide, has established the peak concentration and decay time for mafenide in the saline layer over the wound. Pseudomonas inhibition under identical concentrations was studied.Peak concentrations of 1,200 mg per deciliter of saline were observed after 2 hours. These levels decayed to 400 mg after 10 hours. Remoistening the dressing was required to achieve the peak and duration just mentioned. Pseudomonas inhibition of 88% of discs was present at 1,200, 800, and 700 mg concentrations. This dropped to 44% at 550 mg and 0 at 400 mg. The effective anti-Pseudomonas period was, therefore, 6 hours.

摘要:

Increased evaporative water loss following thermal injury sometimes results in electrolyte abnormalities, negative nitrogen balance, and hypothermia. Because different biological dressings have been claimed effective in diminishing evaporative loss, a prospective study was designed to compare them. Cadaver allograft, porcine xenograft (sheet and meshed), and amnion were placed on 28 granulating wounds for twenty–four hours. Water loss was then measured with an Evaporimeter, revealing that in both full–thickness and partial thickness wounds, allograft was twice as effective as sheet porcine and five times as effective as meshed porcine or amnion. In the absence of available cadaver allografts, sheet porcine xenograft is a satisfactory substitute for use on granulating wounds to diminish evaporative water loss, while amnion and meshed porcine are less effective.

摘要:

A negative attitude toward the treatment of advanced malignancy of the head and neck is frequently encountered. Aggressive therapy, at least for certain patients, is reasonable, and the assessment of certain factors in choosing candidates for such therapy is important. Illustrative case presentations demonstrate that a meaningful number of patients receive palliation or even cure with radical therapy. In view of the grim choices, it seems appropriate to take a positive, if radical, approach when the patient is highly motivated.

摘要:

We present a series of 10 free composite foot flaps used in 9 patients for floor–of–mouth and mandible reconstruction after composite resection. This one–stage repair replaces the soft tissue as well as the bone that has been resected. The flap is easily obtained from the foot, and is tailored to meet the requirements of the mouth and jaw defect. Donor site morbidity is surprisingly low: two flaps were lost from vascular obstruction, and 1 from delayed infection at ten days. The surviving flaps have provided good cosmetic and functional results. Bony union has occurred in half the grafts, and satisfactory firm fibrous union in the remainder. The flap is also useful for late reconstruction in “oral cripples,” and may be used with the skin internally or externally as required. We are pleased with the versatility of this flap in complicated reconstructions.

摘要:

Blindness following blepharoplasty is a well–documented complication. Removal of orbital fat is common to most cases in which such blindness occurs. We present a patient who was referred to us following blepharoplasty involving orbital fat removal in all four lids with subsequent onset of bilateral visual loss. Visual acuity in the right eye has remained no light perception and in the left eye improved from 20/400 to 20/20 following bilateral orbital decompression. An electroretinogram was within normal limits in both eyes. A normal response from the visual evoked response in the left eye and an abnormal response from the visual evoked response in the right eye indicate ganglion cell damage or visual pathway disruption in the right eye, probably secondary to optic nerve ischemia. We conclude that the small nutrient vessels to the optic nerve are more easily compromised than the central retinal artery and are responsible for the visual loss in many of these cases.We believe this to be the first documented case of bilateral visual loss following blepharoplasty and the first electrophysiological study demonstrating the pathophysiology of blindness following blepharoplasty. We advocate rapid orbital decompression to treat this catastrophic complication.

摘要:

Two cases of nasal ala reconstruction are presented, documenting the feasibility of sequentially adding one cartilage–containing composite ear graft onto another in piggyback fashion. The junction between the composites is relatively unnoticeable. This technique enables one to fully correct a nasal defect that has been incompletely reconstructed using a single composite graft, thanks to a partial take or to shrinkage that has reduced the graft bulk more than was anticipated. Defects of a size greater than would be amenable to a single composite graft may be repaired by planned serial addition.

摘要:

In 64 chickens the deep flexor tendon of the third toe was divided and resutured, preserving the sheath and flexor sublimis tendon. The leg was placed in a cast for 35 days postoperatively; in some birds minimal flexion of the toes was induced by electrical stimulation of the deep flexor muscle in the last 17 days of cast immobilization. At day 35 the cast was removed, and the return of flexion carried out in the third toe was measured up to day 60. Assessment of the tendon repair site was at 18, 35, and 60 days.Restored peritendinous connections in specific areas were similar to those in controls. Early movement resulted in fewer adhesions, a significantly higher incidence of free intertendinous spaces (standard error of difference = 6.3, difference = 14.5%), and significant lengthening of bridges between the flexor profundus and phalanx (p = 0.01). The effect of early movement gradually decreased from the dorsal to the ventral structures.
