Early histopathologic changes in experimentally replanted extremities.

Early serial histologic changes in replanted extremities have not been well defined; their contribution to a suboptimal functional result is unknown. With the use of a rat hind limb replantation model to address this question, we studied tissues of the replanted legs by light microscopy from 1 to 60 days after replantation. Although early lesions were consistent with ischemic injury, the chronic preparations were remarkably normal, and the lesions were more consistent with denervation. Poor function in clinical replantations may be a reflection of more pronounced versions of these pathologic lesions.

The use of methyl methacrylate in a two-stage correction of Crouzon's/Apert's deformity.

We have employed a two-stage operative approach to the correction of Crouzon's/Apert's deformity. Extensive use of methyl methacrylate in cranioplasty and frontal bone advancement is employed to obtain finely detailed contours with excellent stability. By adhering to principles of separation of oral contamination and the methyl methacrylate, as well as the provision of adequate soft tissue coverage of the methyl methacrylate, the problems of infection and soft tissue breakdown can be minimized.

Facial fractures in trauma victims: the influence of treatment delay on ultimate outcome.

To obtain objective data on the consequences of delayed treatment of facial fractures we reviewed the records of 220 patients who had suffered facial fractures concomitantly with extrafacial trauma severe enough in its own right to warrant hospital admission. Fractures studied were those of the mandible, maxilla, zygoma, and frontal sinus. Seventy-three patients fit inclusion criteria. Most injuries occurred in motor vehicle accidents. Associated extrafacial injuries were common and frequently multiple, the more serious of which generally took priority over the facial injuries in the triage system. The two most common reasons for delay were instability of the patient's neurological status, or initial non-recognition or poor definition of the facial fracture. Delays in treatment ranged from 0 to 24 days. In patients with mandible fracture only, delay of up to 24 days in definitive treatment led to no noticeable increase in morbidity due to malocclusion, infection, or nonunion. In no other facial fracture did treatment delay lead to an increased incidence of complications. Retrospective analysis of the patients who did suffer complications almost always revealed predisposing conditions that placed these patients at higher risk for poor results.

Results of conservative surgery for middle ear cholesteatoma.

A retrospective study was carried out to analyze treatment results for cholesteatoma at the University of Iowa Hospitals and Clinics. All patients undergoing primary surgical treatment from January 1, 1969 to December 31, 1973 were followed through October 1976. Treatment failures were based on the occurrence of postoperative cholesteatoma. The probability of being disease free for periods up to five years after original surgery was then estimated for each type of operation. Postoperative cholesteatoma occurred after atticotomy in 17%, intact canal wall mastoidectomy in 35%, and modified radical mastoidectomy in 9%. The postoperative cholesteatoma rate in the group having intact canal wall mastoidectomy was more than twice as high for those patients under age nine. The likelihood of being disease free five years after intact canal wall surgery was estimated to be 36% using the life table method. Disease recurrence was significantly higher after intact canal wall surgery compared to other surgical methods. The effectiveness of this method should be evaluated in a randomized, prospective manner to minimize patient selection and treatment bias.

Scarless wound healing: implications for the aesthetic surgeon.

Recent developments in surgery and basic science research offer aesthetic surgeons the prospect of scarless repair. Studies in fetal wound healing provide both cellular and molecular models of optimal tissue healing without scar formation. Furthermore, craniofacial surgeons may one day operate on cleft lip, cleft palate, and other congenital malformations in utero. Cytokine research has begun to unravel possibilities for modulating the wound-healing inflammatory response in hopes of limiting scar formation. This article presents research on these developments and comments on their possible applications to aesthetic surgery.
