“…[23] The Le Fort 1 total maxillary osteotomy was performed first, using standard techniques[24] with a modified step design. [25, 26] After completion of the osteotomy, the maxilla was down- fractured and mobilized until it could be passively positioned forward into an interim splint, with a planned surgical advancement of approximately 10mm. The maxilla was then fixated with four 2.0 mm L-shaped bone plates, placed at the piriform rim and zygomatico-maxillary buttress regions bilaterally.…”

Purpose To directly compare the clinical effectiveness of maxillomandibular advancement (MMA) and uvulopalatopharyngoplasty (UPPP)—performed alone and in combination—for the treatment of moderate to severe obstructive sleep apnea (OSA). Methods The investigators designed and implemented a retrospective cohort study composed of subjects with moderate to severe OSA (baseline AHI >15). The predictor variable was operative treatment and included: MMA, UPPP, and MMA followed by UPPP (UPPP/MMA). The primary outcome variable was the apnea-hypopnea index (AHI) measured preoperatively and 3–6 months postoperatively. Other variables were grouped into the following categories: demographic, respiratory and sleep parameters. Descriptive and bivariate statistics were computed. Results The sample was composed of 106 subjects grouped as follows: MMA (n=37), UPPP (n=34), and UPPP/MMA (n=35) for treatment of OSA. There were no significant differences between the three groups for the study variables at baseline, except for AHI. Surgical treatment resulted in a significant decrease in AHI in each group: MMA (baseline AHI, 56.3 ± 22.6 vs. AHI after MMA, 11.4 ± 9.8; P <0.0001), UPPP/MMA (baseline AHI, 55.7 ± 49.2 vs. AHI after UPPP/MMA, 11.6 ± 10.7; P <0.0001) and UPPP (baseline AHI, 41.8 ± 28.0 vs. AHI after UPPP, 30.1 ± 27.5; P = 0.0057). After adjusting for differences in baseline AHI, the estimated mean change in AHI was significantly larger for MMA compared to UPPP (MMA AHI, −40.5 vs. UPPP AHI, –19.4; P = <0.0001). UPPP/MMA was no more effective than MMA (P = 0.684). Conclusion The results of this study suggest that MMA should be the surgical treatment option of choice for most patients with moderate to severe OSA who are unable to adequately adhere to CPAP.

“…Inúmeros estudos avaliaram a estabilidade do reposicionamento anterior da maxila 1,9,11,14,16,18,20,23,27,30,31,32 . Estes trabalhos freqüentemente apresentam grupos de pacientes heterogêneos, ou seja, um único grupo envolvendo indivíduos fissurados e não-fissurados, cirurgias segmentadas e únicas de maxila, associação ou não com cirurgias de mandí-bula, utilização de diferentes métodos de fixação, o que implica em dificuldades para definir qual o motivo real da recidiva.…”

Este estudo cefalométrico retrospectivo foi proposto objetivando analisar a estabilidade do reposicionamento anterior da maxila, utilizando-se a osteotomia Le Fort I. A amostra consistiu de 30 telerradiografias de dez pacientes submetidos a um avanço cirúrgico da maxila, sem segmentação desta ou associação com qualquer cirurgia na mandíbula, realizado pela Área de Cirurgia Buco-Maxilo-Facial da Faculdade de Odontologia de Piracicaba -Unicamp. A mesma técnica de fixação interna rígida foi utilizada para todos os pacientes, e nenhum enxerto ou substituto ósseo foi usado. Três radiografias cefalométricas laterais foram realizadas para cada paciente, nos períodos pré e pós-operatórios imediatos, e com, no mínimo, seis meses após a cirurgia. Sobre estas radiografias foram feitas linhas de referência horizontal e vertical. Os pontos cefalométricos utilizados para calcular as mudanças de posição da maxila foram tanto esqueléticos, quanto dentários. A análise estatística (teste t de student pareado) não demonstrou diferença estatística significante entre os intervalos pós-operatórios imediato e com no mínimo seis meses. Concluímos que o reposicionamento anterior da maxila, utilizando-se a osteotomia Le Fort I, com fixação interna rígida e sem o uso de enxertos autógenos ou qualquer substituto ósseo, é um procedimento estável. ResumoPalavras-chave: Osteotomia Le Fort I. Estabilidade. Fixação interna rígida. Cirurgia ortognática.
