Aesthetic and functional outcome of surgical and orthodontic correction of bilateral clefts of lip, palate, and alveolus.

OBJECTIVE: To assess the aesthetic and functional long-term results of surgical and orthodontic treatment of patients with bilateral cleft lip, palate, and alveolus. DESIGN: Long-term follow-up study. SETTING: Teaching hospital in Austria. PATIENTS: Twenty adult patients who had been operated on as children for bilateral cleft lip, palate, and alveolus. INTERVENTIONS: Lateral cephalometric and model analysis. The sum of all mesiodistal tooth diameters in the maxilla and mandible were compared with standard Bolton tracings. MAIN OUTCOME MEASURES: Aesthetic and functional results. RESULTS (MODEL ANALYSIS): The upper arch was too wide in 12 patients and the mandibular arch was too wide in 4 patients. In 11 patients, the lateral teeth were crowded, and all had a persistent transverse space deficit and a reduction in sagittal measurements. Fifteen patients had alveolar midline displacement of the maxilla as well as of the mandible. RESULTS (LATERAL CEPHALOMETRIC MEASUREMENTS): The lateral cephalograms showed a mean sella-nasion-A point angle of 77 degrees and a maxillary baseline-nasion-sella line angle of 9 degrees, indicating a tendency toward maxillary retrognathia. An anterior facial height index of 42% (compared with the standard 58%) indicated a slight reduction in midface height with consequent increase in the height of the lower face. CONCLUSION: There is specific growth impairment of the midface in adults who were treated as children for bilateral clefts of lip, palate, and alveolus. An optimal result can be achieved only by additional orthognathic surgery (Le Fort II osteotomy).

[Combined surgical-orthodontic correction for mandibular protrusion].

Through the analysis of the treatment plans and the results of 159 patients with mandibular prognathism, the authors emphasized that orthodontic treatment plays an important role in the combined procedure in which the aims of orthodontic treatment include eliminating dental compensation, aligning the teeth, harmonizing arch compatibility, adjusting and maintaining occlusal relationship. The choice of surgical procedure used for setting back the mandible is closely related to the result of pre-operative orthodontic treatment. The body step osteotomy and vertical ramus osteotomy are the most commonly used procedure to set back the mandible after pre-operative orthodontic preparation.

The surgical-orthodontic correction of maxillary deficiency.

To date surgeons have primarily emphasized advancement of the retrusive or retodisplaced maxilla. There has been no emphasis on combined surgical-orthodontic treatment sequencing in this deformity. Moreover, the maxilla may be deficient not only anteroposteriorly but also vertically and/or transversely. Frequently, when the maxilla is deficient, two or three of these spatial components of the deformities coexist to various degrees. Thus, the term maxillary deficiency is used here to describe the general nature of the skeletal deformity.
