Delayed pedicle separation in forehead flap nasal reconstruction.

Nasal reconstructions with midline forehead flaps are often plagued by inadequate tip projection and excessively thick alar rims. These problems can be overcome by a combination of preliminary tissue expansion, which gains extra length, and delayed pedicle separation, which allows aggressive thinning of alar rims and shaping of the tip while its blood supply is still fully intact. Only when tip-shaping is completed is the pedicle divided and the reconstruction completed. In our experience this combination of increased flap length and improved tip shape has led to better tip projection and superior overall results. Three representative cases that demonstrate these principles are presented.

Perforator-based flaps for low posterior midline defects.

A new type of flap is described based on unnamed perforators located near the midline of the lower back region. Such flaps combine the superior blood supply of the myocutaneous flap with the lack of donor-site morbidity of a skin flap. Five clinical cases are presented, showing how such perforators can augment skin flaps or create custom-designed island flaps. The dissection of the flap is described, and further possibilities for its use are suggested.

The morbidity of perineal wounds following abdominoperineal resection for rectal carcinoma.

The clinical charts of 44 patients who underwent an abdominoperineal resection for adenocarcinoma of the rectum at Roswell Park Memorial Institute were retrospectively reviewed. The morbidity of an open perineal wound versus the closed perineal wound were evaluated. All of the patients received a Nichol's bowel preparation and following the abdominal portion of the dissection reperitonealization of the pelvic floor was performed. The overall morbidity for the open perineal wounds was 21% compared to a morbidity of 63% for the perineal wounds that were closed primarily. The mean length of hospitalization from the time of abdominoperineal resection was 21 days for the open perineal group and 22 days for the closed perineal group. The inclusion of wound sinus tracts in our morbidity assessment may explain the higher complication rate of the closed wound group than previously reported in the literature. This retrospective review emphasizes that the morbidity of the open perineal wound following abdominoperineal resection has been overemphasized. One is trading a potentially increased incidence of septic wound complications in the closed perineum for a protracted wound closure in the open perineum.

Fluctuations of the atrial cycle length and A-V delay with a universal (DDD) pacemaker.

The electronic characteristics of a new universal (DDD) pulse generator can result in significant shortening of the atrial cycle length (A-A interval) and shortening of the atrioventricular (A-V) interval beyond the programmed values. These pacemaker arrhythmias are entirely compatible with normal function and must not be interpreted as malfunctions.
