Mandibular canine tooth luxation injury in a dog.

A mixed breed dog was presented for lateral luxation of the mandibular left canine tooth following oral trauma. This case report describes the management of this injury including reduction, stabilization using a wire reinforced acrylic splint, and standard endodontic therapy of the mandibular left canine tooth.

Vertical distraction of fibula transplant in a case of mandibular defect caused by shotgun injury.

This case demonstrates the successful aesthetic and functional reconstruction of a complex facial gun-shot injury with extended bone defects and soft tissue destructions using a 3-step procedure. Initially, a reconstruction plate was inserted, later a fibula transplant enabled the basic reconstruction and finally was distructed in a 3rd session. The rationale behind the sequencing of surgical sessions was the extended bony defect and soft-tissue destruction. The main problem in this type of wound is hypoxia or anoxia of the receptor bed for the transplant. A microvascular anastomosized bone transplant is necessary for sufficient oxygen tension in the recipient site. The anatomical dimensional disproportion of the transplanted free fibula graft and the shape of the mandible were corrected prior to the insertion of dental implants by means of vertical distraction.

The "Eve" procedure: the transfer of vascularized seventh rib, fascia, cartilage, and serratus muscle to reconstruct difficult defects.

Very few microvascular units entertain the possibility of simultaneous vascularized transfer of bone, cartilage, muscle, and gliding fascia. In exceptionally complex conditions with loss of an essential joint, adjacent bone and functional muscle, reconstruction of all these structures at once may be necessary. At the same time, gliding tissue is often required to cover tendons. Reconstruction in one sitting prevents formation of dense scar tissue due to multiple interventions. Additionally, less bone resorption is seen if vascularized bone is used. Therefore, a more undisturbed tissue composition at the end is guaranteed. Moreover, rapid rehabilitation of moving function is possible with improvement in the final result. Finally, morbidity is lowered by using a single donor site, and costs are minimalized. We present four unique cases in which the seventh rib including the costochondral junction with overlying serratus muscle, branches of the thoracicus longus nerve, and adjacent fascia have been transferred as a microvascular unit to reconstruct two severely damaged hands and two other complex injuries. In analogy with the Bible story of the creation of "the woman," it is called the "Eve" procedure. The vascularized rib was used to reconstruct a first and fourth metacarpal bone, the ascending ramus of the mandible, and the clavicle. The rib cartilage was sculptured in four cases to reconstruct an articular surface. The serratus muscle served as coverage and filling for lost tissues. It also was used as a soft bed for facial nerve repair. In two cases muscle reinnervation was performed. The fascia provided gliding tissue surrounding reconstructed tendons or articular surfaces. In all cases a high degree of function was obtained with a good cosmesis. Rehabilitation was uneventful, and no reinterventions have been necessary. Donor-site morbidity was low. Therefore, this flap proved to be successful in complex injuries where bone, cartilage, muscle, and gliding tissue were needed simultaneously. Dynamic reconstruction was attempted in two cases and was successful in one.

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.
