Analysis and results of treatment of established posttraumatic facial deformities.

Abstract

The clinical records of 125 patients undergoing treatment for posttraumatic facial deformities (PTFD) from 1979 to 1990 were retrospectively reviewed. Patients with complex fractures had a combination of at least three of the major fracture categories [Le Fort I, II, III; naso-orbital-ethmoid (NOE); zygomatic; frontobasilar; and mandibular]. Twenty-five patients (20 percent) were found to have severe posttraumatic facial deformities resulting from a complex facial fracture pattern. Sixteen were males and nine were females, and their ages at the time of our first reconstructive procedure ranged from 22 to 64 years (mean 33 years). All patients presented to our clinic with severe posttraumatic facial deformities from 1 month to 26 years (mean 5 years) after original injury. The number of prior reconstructive attempts averaged two (range 0 to 9). Arbitrary severity scores assigned by us were mild in 4, moderate in 12, and severe in 9 patients. Once treatment was initiated in our clinic, the average number of operations was 3.76 until completion (range 1 to 15). Surgical treatment was aimed first at reestablishing proper skeletal, vertical, transverse, and sagittal proportions. Once skeletal foundations were reset, the more delicate naso-orbital-ethmoid and lateral canthal relations were addressed. Of the 25 patients, 13 (52 percent) suffered a complication at some point during their surgical management. In these 13 patients, 20 complications occurred in a total of 94 operations for an overall complication rate of 21 percent. Fifteen of the 20 complications were related to infection. Skeletal abnormalities in patients with posttraumatic facial deformities can generally be corrected with current craniomaxillofacial techniques. Ultimately, an excellent result in terms of skeletal reconstruction is compromised by the status of the surrounding soft tissue. More in-depth knowledge of the nature and magnitude of the initial and subsequent soft-tissue injury will contribute to our ability to treat these disfiguring posttraumatic sequelae.
