Vascularized full-thickness parietal bone grafts in maxillofacial reconstruction: the role of the galea and superficial temporal vessels.

Reconstruction of bony structures of the face is always a problem as big as the defect and the function that must be replaced. Everything from simple grafts to sophisticated distant bone flaps has been used. Based on the studies of Cutting et al., Psillakis et al., and Casanova et al., we have developed the full-thickness galeoparietal bone flap, initially for mandibular reconstruction, but of great use for all maxillofacial reconstructions. From July of 1987 to December of 1988, 14 patients have been operated on. The experience with this flap is shown in four patients as follows: primary reconstruction of a mandible as a result of ameloblastoma, secondary reconstruction of a mandible with associated old fractures and malalignment of segments, bilateral malar reconstruction in a patient with Treacher Collins syndrome, and severe sequelae of an already treated Romberg case. Small variations could be made to best accommodate the technique used to the defect we were treating. Some technical details, the experience, the results, and possible sequelae or complications are also discussed.

The extended subperiosteal face lift: a definitive soft-tissue remodeling for facial rejuvenation.

The subperiosteal face lift described by Psillakis has been criticized for not showing a more dramatic improvement over conventional brow/face lift procedures. His approach also has a significantly high incidence of nerve injury. This study reports our anatomic findings and surgical modifications, which have permitted a significant improvement in the safety of execution and clinical results using the subperiosteal face lift concept. Pertinent points of applied local anatomy and dissection techniques are as follows: First, we use extensive interconnected subperiosteal dissection that includes the entire zygomatic arch. This allows better repositioning of the deep soft tissues of the entire upper face, most of the midface, and indirectly, key structures of the lower face. Second, the upward pull of the muscles of the cheek and mouth will produce an elevation of the corner of the mouth, affecting positively the smiling mechanism, the oral frowning, and the jowls. Third, the dissection deep to both layers of the temporal fascia decreases the risk of injury to the frontalis nerve. Fourth, the temporal fascia is used as a lifter and anchoring element of the entire cheek-perioral soft tissues as opposed to the periorbital fibrofatty tissues. This will decrease the risk of injuring the frontal and zygomatic branches of the facial nerve. These modifications have been used in 28 patients. Our rate of patient satisfaction has been high, and no complications with regard to nerve injury have been observed. This compares favorably with our initial 60 patients, in whom the Psillakis or Tessier approach was used. In these patients, there was an 11 and 20 percent rate of nerve injury, respectively.

Geometrical planning for the correction of orbital hypertelorism.

Orbital hypertelorism may be associated with a variety of deformities affecting several elements of the craniofacial skeleton. Shortness of the central portion of the face represented by a wide, short nose and anterior open bite is frequently combined with the exaggerated interorbital distance. With the mobilization of the two halves of the face it is possible to approximate the orbits, simultaneously elongating the center of the face and normalizing the maxillary alveolar ridge. A technique is described to plan the operation geometrically in order to predict accurately the skeletal correction, the change of the inclination of the eye slant, and the modification of the axis of the teeth.

Midface retrusion.

Experience with 162 patients for whom a midface advancement was performed over the last 10 years is reported. The series includes cases of primary maxillary hypoplasia, post-cleft deformities, and major craniofacial anomalies. The indications and techniques applicable to each particular deformity are discussed and final results are analyzed. The overall facial esthetic concept is emphasized to ensure achievement of not only a good functional result, but also a pleasant appearance.
