摘要:

In most cases, after successful correction of primary cleft lip deformity, some problems remain to be solved. One of them is nostril sill depression, which should not be overlooked in cleft lip repair. However, there have been few reports on the anatomy of the depressed nostril sill and methods for augmenting the sill depression. The anatomy of the depressed nostril sill, its relationship to surrounding tissue, and the gross features of nostril sill depression in cleft lip deformity were reviewed, and a method in which a scar flap and a suture-fixation technique are used was developed for augmenting the depression. The clinical results of this method in 16 patients are presented.

摘要:

The upper lip, given its surface anatomy and morphology, should be no more than 2 cm high. Therefore, to reduce the upper lip we propose an incision at its highest portion similar to the letter M which extends into the nasal vestibula. We aim at a real reduction of the height of the lip as well as restoration of its natural concavity through a scar situated obscurely, and which tends to disappear within a few months postoperatively. In patients in whom the upper lip is less than 2 cm high but the vermilion is minimal, we use Gillies' technique and make curvilinear incisions. We have also observed correction of the perioral wrinkles using this technique.

摘要:

The project described in this article used in vitro tissue culture techniques and flow cytometry to determine if there are alterations in cell morphology in those cells that have been placed in contact with a commercially available medical-grade silicone gel used in mammary implants. We were unable to demonstrate significant changes in cell cycle characteristics following in vitro exposure for 1 to 12 days using human fibroblasts, mouse fibroblasts, and Chinese hamster ovary cells.

摘要:

There are various degrees of expression of the fully developed tubular/tuberous deformity. To develop an adequate treatment plan for this condition, the individual deformities constituting the fully expressed syndrome must be diagnosed. The treatment plan must include maneuvers to correct each deficiency within the syndrome itself. We present the spectrum of abnormalities constituting the tubular/tuberous syndrome and the treatment plan thereof.

摘要:

A buried dermal hammock technique for nipple-areolar reconstruction is described that ensures predictable long-term nipple projection. Fifty-one reconstructions have been done since 1981 with good long-term nipple projection and no complications.

摘要:

To determine the validity and reliability of the physical examination in evaluating abnormalities of the lower eyelid following blepharoplasty, a model using monkeys was developed. One plastic surgeon performed a variety of blepharoplasties, including extensive resection of lower lid skin and/or muscle, and/or the creation of scarring in the orbital septum. Three months postoperatively, a second plastic surgeon and an ophthalmologist examined these monkeys' lower eyelids. Although there was substantial agreement between the observers as to the degree of scleral show and which eye was “worse” in each monkey, the examiners were correct in just 7 of 24 attempts to identify the exact operative procedure that had been performed. This study demonstrates that it is difficult to identify the cause of abnormalities in appearance and position of the lower lid after blepharoplasty. Orbital septal scarring can cause the same degree of scleral slow as excessive skin resection. Muscle resection contributed little to lower lid position.

摘要:

This article describes a model of chronic nerve compression in the rat. The sciatic nerve of adult male Sprague Dawley rats was banded with a 1-cm Silastic tube for varying periods of time. Morphometric analysis, electrodiagnostic studies, and histological evaluation were carried out 3, 5, 8, and 12 months after banding.Histological evaluation at 3 months was normal. At 5 months perineurial thickening was demonstrated. In the periphery of the fascicles, segmental demyelination was noted; central fibers appeared normal. At 8 months there was further epineurial and perineurial thickening. Marked thinning of the myelin was noted in all fibers and evidence of Wallerian degeneration was apparent. Progressive connective tissue and nerve fiber changes were noted at 12 months.Nerve conduction studies after 3 months of compression demonstrated an increase in conduction velocity compared to the normal unbanded control nerves. Progressive slowing of conduction velocity was noted from 5 through 12 months.

摘要:

Presented here is our experience with a new approach to abdominoplasty using a limited incision with liposuction. The indications and advantages of the proposed technique are discussed. The procedure was performed in 20 consecutive cases. The benefits of the procedure are the resultant natural contour of the abdominal wall and umbilicus, the maintenance of the mons pubis at its original site, and, most importantly, a limited scar.

摘要:

A musculocutaneous flap is a simple and effective treatment for the complications which can follow esophageal reconstruction at the cervical portion, such as stricture, fistula, and infection of costal cartilages. After the strictured segment is opened or resected, the resultant esophageal defect can be replaced with the skin patch of a musculocutaneous flap. Then the muscle component of the musculocutaneous flap can be used to form a seal around the previously infected lesion site, an area with the potential for recurrent infection and leakage in subsequent operations. Seven patients were treated this way with satisfactory results.

摘要:

A case is described of tissue expansion of the scalp with resultant erosion of the outer table and diploe of the calvaria. This resorption may have resulted from a prolonged period of expansion, excessive tension from inflation, and/or the nature or location of the defect. In cases of scalp expansion where the loose areolar space has become obliterated, periodic limited computed tomographic scanning may be useful to monitor the integrity of the skull. Postexpansion protective headgear may be indicated in selected patients.
