An algorithm for abdominal wall reconstruction.

Acquired abdominal wall defects result from trauma, previous surgery, infection, and tumor resection. The correction of complex defects is a challenge to both plastic and reconstructive and general surgeons. The anatomy of the abdominal wall, as well as considerations in patient assessment and surgical planning, are discussed. A simple classification of abdominal wall defects based on size, depth, and location is provided. Publications regarding the various abdominal reconstruction techniques are reviewed and summarized to familiarize the reader with the treatment options for each particular defect. Finally, an algorithm is presented to guide the surgeon in selecting the optimal reconstructive technique.

A simplified transblepharoplasty subperiosteal cheek lift.

Surgical treatment of the aging face is continuing to evolve. Recent emphasis has focused on managing the malar region, specifically ptosis of the cheek pad. Several authors have described techniques for correcting facial aging changes in the midface through an endoscopic approach or transblepharoplasty approach. The latter procedure requires a lateral canthoplasty, which adds technical difficulty and potential complications to the procedure. We have modified these procedures and now perform a simplified transblepharoplasty subperiosteal cheek lift without routine canthoplasty or canthopexy. Sixty patients who had this procedure were evaluated. Analysis of these patients revealed that our simplified approach to transblepharoplasty subperiosteal cheek lift provides excellent correction of midfacial aging changes with a low incidence of postoperative complications. This article describes this technique and reviews our results.

Chondrosarcoma of the jaws: clinical findings, histopathology, and treatment.

Three cases of chondrosarcoma involving the jaws are presented, one in the maxilla and two in the mandible. The salient points of clinical presentation elucidated by this series of cases are that a widened periodontal ligament space is present in chondrosarcomas as well as in osteosarcomas, and that a slowly increasing diastema may be the earliest clinical sign. The most important lesson to be learned from the histopathology is that one should not accept a diagnosis of a benign cartilaginous tumor of the jaws. Treatment of these lesions should consist of wide surgical excision and consideration of adjunctive or palliative radiotherapy, especially in the maxilla. It should also be noted that recurrences may develop 10 to 20 years later, and follow-up should be lifelong.

Cavernous hemangioma of the zygoma: report of cases.

Osseous hemangiomas of the facial bones are rare lesions, with most cases occurring in the maxilla and mandible. Reported cases in the zygoma are sparse. Two cases of zygomatic hemangiomas with widely differing presentations are reported. One case in a neonate required surgery to prevent fatal hemorrhage, and the other in an adult required correction of a cosmetic deformity. Each patient presented with a second congenital anomaly. Therapeutic problems associated with these lesions and their management are discussed.

Condylar displacement and temporomandibular joint dysfunction following bilateral sagittal split osteotomy and rigid fixation.

In this study changes in intercondylar width (ICW) and intercondylar angle (ICA) that occurred with rigid fixation after bilateral sagittal split osteotomy and mandibular advancement are documented and correlated with temporomandibular (TM) symptoms, magnitude of advancement, and mandibular shape. Even though individual changes occurred, there was no significant difference between the mean preoperative and postoperative ICA and ICW measurements. There was also no significant difference between the preoperative and postoperative incidence of TM pain or clicking. No correlation was found between the magnitude of advancement and the percent change in ICA or ICW, and the mandibular shape did not correlate to changes in ICW. This study suggests that screw osteosynthesis does not significantly change ICA or ICW. The fact that no significant increase in TM symptoms occurred indicates that the changes in condylar position that did occur were within the range of clinical adaptability of the patients.

Arthroscopy of the temporomandibular joint: an anatomic perspective.

Anatomic relationships in the temporomandibular joint (TMJ) region related to arthroscopic surgery were analyzed in cadaver dissections and dry skulls. The study showed that the maxillary artery and the main bifurcation of the facial nerve are located a safe distance from the usual arthroscopic approaches to the TMJ. The frontal branch of the facial nerve are located a safe distance from the usual arthroscopic approaches to the TMJ. The frontal branch of the facial nerve may be as close as 3 mm anterior to the midpoint of the lateral pole of the condyle. The neurovascular complex of the superficial temporal vessels and the auriculotemporal nerve may also be very close to puncture sites. The roof of the glenoid fossa had an average thickness of 0.9 mm. The external soft tissue auditory canal courses anteriorly to meet the bony external auditory canal. A skin puncture perpendicular to the bony canal was approximately 7 mm anterior to the posterior aspect of the tragus.

Esthetic evaluation of frontal labial morphology after double V-Y closure following Le Fort I osteotomy.

Ten orthognathic surgery patients who had their maxillary circumvestibular incision closed with a double V-Y closure were compared with 10 unoperated controls. Pre- and post-operative frontal photographs were presented to nine oral and maxillofacial surgeons and nine orthodontists. The examiners answered a set of questions designed to evaluate changes in maxillary exposed vermilion height, contour of the Cupid's bow, and the final esthetic result. Results of the study show that any changes in the definition of Cupid's bow or the vermilion height with double V-Y closure are difficult to discern clinically and that this procedure produces an esthetically acceptable outcome.

Frontal soft tissue morphology with double V-Y closure following Le Fort I osteotomy.

This prospective study compares the nasal and maxillary vermillion morphology in three groups of patients who underwent maxillary osteotomies and whose soft tissues were managed by different surgical techniques. Eleven of these patients had simple primary closure (SPC) of the maxillary circumvestibular incision; ten were treated with single V-Y closure (SVY) combined with nasolabial muscle reconstruction, and the remaining 11 were treated with a double V-Y closure (DVY) combined with nasolabial muscle reconstruction. All three groups showed significant increases in the alar dome width. Further inspection of the data revealed that the DVY group showed significant, strong correlations between the preoperative and postoperative vertical vermillion measurements. Although the SVY and SPC techniques showed significant correlations for the same measurements, their correlation values were less. Small significant decreases averaging from 0.5 mm to 1.0 mm were seen in all but one of the vertical vermillion measurements with the DVY technique. Larger individual decreases and increases were seen with the SVY and SPC techniques. These findings suggest a level of predictability in the postoperative vermillion height change with the DVY closure that is not obtainable with the SVY or SPC techniques.
