Superior Pedicle Reduction Mammoplasty Supported with Inferior Pedicle Chest Wall-Based Flap: Refinements to the Technique.

Breast reduction techniques strive to obtain a final aesthetic breast shape. The most difficult issues to address after breast surgery are providing consistent upper pole fullness and preventing recurrent ptosis. Our surgical approach is a superior pedicle vertical scar breast reduction with an inferior pedicle chest wall-based flap to enhance the projection of the breast. We describe our refinements to the previously described similar techniques to provide upper pole fullness with long-lasting breast shape and prevent the bottoming out deformity. Twenty-five patients underwent reduction mammoplasty and/or mastopexy (15 mastopexy, 10 reduction mammoplasty) using modified superior pedicle reduction mammoplasty supported with inferior pedicle chest wall-based flaps between 2009 and 2013. Medical records and follow-up outcomes were retrospectively analyzed. Scar widening was acceptable even for larger reduction cases. The aesthetic results of both reduction and mastopexy cases were satisfying. Upper pole fullness was maintained in the long-term follow-up. Significant bottoming out was not observed. No skin excess was noted at the inferior fold region in any of the cases. In our modified technique, tissue is excised in a beveled fashion under the superior pedicle and pillars, particularly from the lateral; hence, the chest wall flap does not cause tissue excess at the upper infra-areolar site of the vertical scar. Flexibility in choosing the location from which to remove the breast tissue provides a custom-made approach to shape each breast. The long-term results of our technique demonstrate minimal breast descent and sufficient upper pole fullness.

Breast reconstruction using de-epithelialized dermal flap after vertical-pattern skin-sparing mastectomy in macromastia.

INTRODUCTION: Prophylactic mastectomy is performed to reduce the risk of breast cancer in high-risk conditions, and expectations about reconstruction are too high. Implant coverage with healthy tissue and skin reducing as an envelope are two concerns in the treatment of macromastia cases. We present our results obtained with a prosthetic reconstruction technique using an inferior pedicled de-epithelialized dermal flap after vertical-pattern skin-sparing mastectomy in this retrospective study. METHODS: Fourteen patients with macromastia and with a high risk of breast malignancy were treated with breast prosthesis using an inferior pedicled de-epithelialized dermal flap after vertical-pattern skin-sparing mastectomy, and were followed for 6 months to 2 years. RESULTS: Good aesthetic results were obtained in all of the patients with increased patient satisfaction. There were no serious complications and the patients were all satisfied. DISCUSSION: Since there is no dangerous T-point in vertical-pattern skin-sparing mastectomy in contrast to an inverted-T wise-pattern technique, where flaps are connected under great tension and susceptible to separation, it can be used safely in macromastia cases, as in smaller breasts. In addition, a de-epithelialized dermal flap is quite useful to cover the inferior pole of the prosthesis and it eliminates the need for an acellular dermal matrix.

Minced nerve tissue in vein grafts used as conduits in rat tibial nerves.

INTRODUCTION: Peripheral nerve injuries are encountered frequently in clinical practice. In nerve repair, an end-to-end suture is the preferable choice of treatment. However, where primary closure is not possible, the defect is to be repaired with a nerve graft. METHODS: A total of 21 female Wistar rats weighing 230 to 290 g were used in the study. They were classified into the following 3 groups: (I) nerve graft, (II) vein graft, and (III) minced nerve graft. In group I, after exposure of the tibial nerve, a 1-cm-long nerve gap was created on the tibial nerve, and the defect was repaired epineurally by using the autogenous nerve. In group II, the 1-cm tibial nerve defect was repaired by using an autogenous vein graft. In group III, a 1-cm nerve graft was divided to 3 equal parts, with one of the nerve parts being minced with microscissors and placed in the vein graft lumen. Thereafter, a 1-cm tibial nerve defect was repaired by the vein graft filled with minced nerve tissue. The tibial function indices (TFIs) were calculated for functional assessment using the Bain-Mackinnon-Hunter formula. Light and electron microscopic evaluations were performed for morphometric assessment. In addition, the myelinated fibers were counted in all groups. RESULTS: The TFIs of group II were found to be the lowest among all the groups after the sixth week, whereas the TFI of group I was found to be better than the other groups after the sixth week. There was no difference in TFIs between group I and group III. On the basis of the number of myelinated fibers, there was no statistically significant difference between group I and group III, whereas the difference was significant (P<0.05) between groups I/III and group II. Presence of peripheral nerves in light microscopic evaluation revealed normal characteristics of myelinated fibers in all groups. The myelinated axon profile was near normal in the nerve graft group in electron microscopic evaluation. However, there were more degenerated axons with disturbed contours and vacuolizations in the vein graft group compared to the minced nerve graft group. CONCLUSIONS: We can conclude that using minced nerve tissue in vein grafts as a conduit increases the regeneration of nerves (almost like the nerve graft group) and it may not be caused by donor-site morbidity. It can be used in the repair of nerve defects instead of autogenous nerve grafts after further experimental evidence and clinical trials.

Effects of time lapse on results of partial nerve injury repair.

Partial nerve severance is a problem in peripheral-nerve surgery. It should be repaired without tension for a good functional result. There is usually no trouble in repairing acute injuries. But, as time passes, it may be difficult to establish a proper end-to-end repair, and this cause more tension at the repair sites. In this study, the critical time lapse for a deleterious effect was evaluated. Thirty rats were used, with partial nerve severance repaired immediately or at 10 or 20 days later. At 2, 4, 8, 12, 20, and 28 weeks, functional assessment of nerve regeneration was performed using walking-track analysis. Functionally, the sciatic index values were very close to each other in the immediate and 10-day-delay group, but the difference between these groups and the 20-day-delay group was statistically significant. The study suggests a critical period of about 2 weeks after partial nerve section before irreversible changes occur. Although this is not applicable to human models, it implies further work on a primate model for determining a reliable time-lapse period.

Two applications of end-to-side nerve neurorrhaphy in severe upper-extremity nerve injuries.

End-to-side and side-to-side techniques (what we call alternative nerve repair techniques) have been investigated in detail in both experimental and clinical studies. There have not been any large series, but only some case reports describing either successful or disappointing functional results in the recent literature. Two cases presented here were of two extreme examples of nerve injuries that had no chance for direct repair; alternative choices were performed. One was a side-to-side neurorrhaphy between the ulnar and median nerves, and the other was an end-to-side nerve repair of the median and radial nerves to the ulnar nerve. Both patients regained their diminished protective sensation and returned to their occupations. Based on these results and our review of the current literature, we consider alternative nerve repair techniques to be reasonable, prudent, and scientific choices for the treatment of some challenging nerve injury cases.

Management of maxillofacial problems in self-inflicted rifle wounds.

Severe gunshot wounds to the face, produced by high-velocity rifles or shotgun blasts, present a formidable challenge to reconstructive surgeons. In this study, the results of 14 cases with gunshot wounded faces caused by fire from rifles are presented, and the principles of the management of those victims were determined. These patients had attempted to commit suicide and placed the muzzles of the rifles beneath their chins. The ages of the patients ranged from 20 to 24 years, with a mean age of 22 years. These wounds were caused by close-range gunshots (<10 cm), and the missiles had high velocity (more than 800 m/second). All patients had wounds in their submental triangle areas. The exit sites of the missiles differed among patients. All exit wounds were in the angle limited by the deviation from the gun-barrel axis. After clinical and radiologic evaluation and conservative debridement of all devitalized tissues, the fractures were reduced and stabilized appropriately. Large bony defects were treated by bone grafting, and all soft tissue lesions were closed in layers. The entrance and exit sites were covered primarily after thorough debridement except one case whose defect was reconstructed with bilateral sternocleidomastoid (SCM) flaps, one for submental skin and the other for the mouth floor. Intraoral soft tissues were then repaired by primary closure, tongue flaps, or SCM flaps in case they were necessary. Free tissue transfers were not required for treatment of secondary soft-tissue problems. Resolution of tissue edema, softening of scars in time, and insertion of bone graft may improve the deformity significantly. The initial anatomic reconstruction of the existing bone skeleton and the maximal use of regional tissue for cutaneous reconstruction provide an esthetic appearance that can never be duplicated by secondary reconstruction.

Y-V advancement with Z-plasty: an effective combined model for the release of post-burn flexion contractures of the fingers.

Volar contractures of the fingers are the commonest sequel to burns of the hands. These have been treated by using various basic techniques of Plastic Surgery. Recently, a combination of these techniques has been used for improving the results more. In the study, two well-known techniques, Y-V advancement and Z-plasty, were combined to improve release of linear flexion contractures of the fingers, including thumbs. Its mathematical representation is presented. Ninety-eight PIP joints (IP for thumb) of 37 patients were treated with this technique and their results were followed-up for about 8 months. The gains were greater using the combined technique than for the usage of either alone. It was concluded that this model could serve as one of the effective combinations of the basic techniques in the treatment of volar finger contractures.

Secondhand management of "spaghetti wrist": do not hesitate to explore.

"Spaghetti wrist" consists of the severance of at least three structures, of which one is the median nerve or the ulnar nerve, and it is one of the most devastating injuries of the hand. Close follow-up and appropriate rehabilitation are mandatory for management; however, this is not easy in patients whose previous treatment was accomplished elsewhere. The authors explored 28 patients with spaghetti wrist injuries who were previously operated. The study included those with areas of the hand, innervated by the injured nerve, that were partially or completely anesthetic. Limited sensorial return was also uniform and partial anesthetic sites were usually limited to only a finger or either side of a finger. When explored, six nerves had a normal appearance and 18 nerves had neuroma-in-continuity on their repair sites. The median nerves of the remaining five patients had been repaired not to their original proximal or distal stumps, but to adjacent tendons. A nerve tissue bridge from the proximal to the distal stump developed in all these patients. The authors conclude that hand surgeons should explore the previous repair sites if they have any suspicions regarding the technique performed and the success of previous management of spaghetti wrist. Any partial sensorial return to a limited area may be the result of axonal secondary pathways; thus, early exploration during the critical period can protect these patients from paralyzing sequelae of the injured nerves.

Bilateral side finger transposition flaps in the treatment of chronic postburn flexion contractures of the fingers.

The authors present a surgical method of releasing postburn flexion contracture of the finger by two separate transverse incisions and covering the skin defects by transposing two random-pattern flaps from both sides of the finger. One of the proximally based flaps was transposed from one side of the proximal phalanx and the other flap was transposed from the opposite side of the middle phalanx. Because the flaps were raised from different sides of different phalanxes, the donor sites were closed primarily. A total of 37 fingers (14 hands, 11 patients) were treated with this method. The patients were all men aged 20 to 24 years old. The mean follow-up period was 9 months. The lack of extension of the proximal interphalangeal joints of the fingers was improved by approximately 45 deg using the described method. The authors conclude that this method can be used effectively in the treatment of mild to moderate postburn flexion contractures of the fingers.

Otoplasty: anterior scoring and posterior rolling technique in adults.

The corrective otoplasty is the aesthetic surgery most frequently performed in childhood. Some people neglect this deformity because it does not cause functional problems and seek treatment in their teen or adulthood. In this age group, the development of ear is no longer major concern. In this study, 178 adult patients were treated by using a modified form of anterior scoring technique for the correction of their prominent ears. In this method, after anterior scoring, as described by Chongchet, the free edge of ear cartilage was rolled over itself posteriorly and fixed. This cartilage structure was covered with subcutaneous and perichondrial flaps to establish a natural contour. The patients were followed for at least six months and their results were evaluated in terms of complications and patient satisfaction. This technique enhances the aesthetic results of otoplasty by making a smoother surface and eliminating sharp edges, and is a reliable choice in the correction of prominent ears.
