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.

Although nerve graft is still the only reliable choice in repair of defects in peripheral nerve structure, it has the disadvantage of donor nerve morbidity and of sometimes being unavailable. It has long been researched in alternate nerve grafts with other materials. Studies have shown that nerves could regenerate across short nerve gaps through various conduits, such as veins, pseudosheaths, and bioabsorbable tubes. Despite encouraging studies, their functional results remain unclear. The present study used 40 rats, in which nerve grafts, vein grafts, and epineurial tubes were placed into 1-cm gaps in sciatic nerves created by resection. In one group, sciatic nerves were denuded of the surrounding epineurium, to assess the possible morbidity caused by epineurial sheath technique. At 2, 4, 8, 12, 20, and 28 weeks, functional assessment of nerve regeneration was performed using walking track analysis. The number of myelinated fibers and fiber diameters was measured and electron microscopic evaluation performed. Functionally, the index values were very close to each other in nerve graft and epineurial sheath groups. Morphometric analysis showed significance between the groups. The result of denuded sciatic nerve group was the same as the base track values. It was concluded that the ready availability of epineurial sheath as a conduit to span short nerve gaps could eliminate the morbidity associated with nerve graft harvest and capitalize on the potential benefits of neurotrophism in directing nerve regeneration.

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.

The authors present their experience with the surgical treatment of capsular contracture to achieve better results in a safe, predictable, and practical way, and discuss the possible treatment modalities. They simply advise leaving the capsule intact, even if it is calcified, and create another pocket, rarely in the front or, more typically, at the back of the capsule. If the breast tissue is also ptotic, a mastopexy procedure may be added to the procedure, in addition to augmentation, with a rather small prosthesis placed in the new pocket or, occasionally, in the old one. External, forceable massage is not advisable to treat the capsule. Open capsulotomy and/or partial capsulectomy can be applied to release the capsule. However, it is not advisable since recurrence is usually inevitable. The purpose of this paper is to present a series of surgical procedures to avoid the problems created by the capsule and present different cases with good results.

A method of repair is described for correction of abnormally enlarged nipple-areola complex following both periareolar mastopexy and pregnancy. Although during periolar mastopexy or reduction mammoplasty regular subcuticular dermal sutures may control the enlargement of nipple-areola complexes initially, the periareolar scar becomes hypertrophic and areolar spreading occurs to some extent. Periareolar mastopexy techniques are indeed advisable only for minimal hypertrophies or ptosis of the breast, especially for areolar asymmetry, if an acceptable, normal-size areola is expected. The authors believe that in periolar mastopexy or reduction mammoplasty cases resulting in enlarged nipple-areola complexes, the size of the areola can also be corrected by reduction mammoplasty or mastopexy using vertical bipedicle techniques. Although surgery results in an inverted T incision, the shape of the breast is more acceptable and the size of the areola does not enlarge with time.

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.
