摘要:

The dorsal nasal flap and its modifications have proved reliable in the coverage of defects on or adjacent to the tip of the nose. However, the problems inherent in the nature of the flap are limited rotational movement afforded by the pedicle, visible scars crossing the dorsum and the natural concavity of the alar crease, skin thickness discrepancy between the flap and the skin, and dog-ear deformity created by the rotation. The purpose of this study was to design a new modification of the dorsal nasal flap, in the highlight of a cadaveric study, that can overcome the traditional drawbacks. Ten adult human cadavers were used to study the vascular basis of the flap and to simulate application of the flap. Cadaveric dissections demonstrated that a skin island over the nasal dorsum and glabellar area can be elevated safely based on a dual axial supply (i.e., the terminal branches of the angular artery and vein bilaterally), and can be advanced easily in a V-Y manner to cover the nasal tip defect. The result obtained in the clinical case showed that the V-Y island dorsal nasal flap provided a sizable amount of skin with more appropriate texture and color for coverage of the nasal tip defect without tension or secondary deformity.

摘要:

A 3-month-old infant was administered high-dose systemic prednisolone for management of a hemangioma of the nasal sidewall. After 10 weeks of therapy, medical evaluation of weight loss disclosed hypertrophic obstructive cardiomyopathy. After discontinuation of the steroid, the cardiomyopathy resolved.

摘要:

A variety of local flaps have been described for chest wall and bronchopleural fistula reconstruction. When local options cannot be used because of previous surgery, trauma, radiation, or body habitus, free flaps become an acceptable option. The authors report a case of persistent bronchopleural-cutaneous fistula treated with a free latissimus dorsi musculocutaneous flap that obliterated the right chest cavity, closed the site of empyema drainage, and aided healing of a bronchopleural fistula. Surgical technique including anastomosis to the innominate vein is described.

摘要:

Documenting the rate of rupture of silicone breast implants appears to be deceptively easy. Largely because of the phenomenon of “silent rupture,” it isn’t. The authors explore the various technical biases (selection, misclassification, and confounding) and methodological problems that have plagued much of the research conducted to date. By means of a series of illustrations, they argue that explantation has limited utility. Noninvasive techniques have to be used to gather the proper type of data on the timing and frequency of these events. Only with the proper incidence data will researchers be able to identify better the different mechanisms underlying implant rupture and the relative importance of each. The authors recommend that better and standardized definitions of implant rupture be developed, that greater recognition be given to the technical biases and a greater effort be made to eliminate them from investigations of implant rupture, and that more research be conducted by multidisciplinary teams. Because of the growing awareness of the complexity of this issue, the authors also recommend that properly constituted advisory teams be used to provide comprehensive oversight of future research projects from beginning to end.
