ABSTRACT

RESUMEN: Objetivo: Describir los cambios de la pirámide nasal al realizar una osteotomía Le Fort I y el manejo cosmético complementario a la cirugía ortognática. Material y método: Se realizó una búsqueda electrónica en las bases de datos PubMed, EBSCO, Scopus, The Cochrane Library, y en el metabuscador Epistemonikos a través de las palabras clave "Le Fort 1", "Orthognathic Surgery", "Maxillary Surgery", "Nasolabial Changes", "Nasal Change", "Nasolabial Esthetics", "Soft Tissue", "Nasal Profile", "Nose" y "Cosmetic", relacionadas entre sí con los términos booleanos AND y OR. Resultados: se seleccionaron 25 artículos: 15 estudios observacionales, 5 revisiones narrativas, 3 ensayos clínicos y 2 notas técnicas. Conclusión: se establece cierto patrón que permitiría predecir cambios que sufrirá la nariz: aumento en la proyección nasal, disminución del largo columelar y ensanchamiento de la base alar son uno de ellos. En otros aspectos como el ángulo nasolabial o la posición final de la punta nasal no se ha logrado definir un patrón común. Para evitarlos se han descrito muchas técnicas. Sin embargo, falta mayor evidencia.


ABSTRACT: Objective: To describe the changes of the nasal pyramid when performing a Le Fort I osteotomy and its cosmetic management complementary to the orthognathic surgery. Materials and Methods: An electronic search was made in PubMed, EBSCO, Scopus, The Cochrane Library and Epistemonikos using the keywords "Le Fort 1", "orthognathic surgery", "maxillary surgery", "nasolabial changes", "nasal change", "nasolabial esthetics", "soft tissue", "nasal profile", "nose" and "cosmetic" related to each other with the Boolean terms AND and OR. Results: 25 articles were selected; 15 observational studies, 5 narrative reviews, 3 clinical trials and 2 technical notes. Conclusion: Nasal changes tend to follow a certain pattern that allows to predict them when facing surgery: increase of nose projection, decrease in columellar length and widening of the alar base, among others. As for other aspects such as the nasolabial angle or the final position of the nasal tip, it has not been possible to define a common pattern. To avoid them, several techniques have been described. However, more evidence is needed.

ABSTRACT

RESUMEN: Introducción: La anomalía esqueletal clase II posee un 16 a 22,5% de prevalencia mundial. Cuando estos pacientes se someten al avance mandibular mediante osteotomía sagital de rama mandibular pueden presentar un grado de inestabilidad postoperatoria evidenciándose como recidiva de éste. Objetivo: Describir la estabilidad del avance mandibular mediante osteotomía sagital bilateral de rama mandibular en pacientes clase II esqueletal. Material y método: Se realizó una búsqueda electrónica en las bases de datos PubMed, EBSCO, The Cochrane Library, Tripdatabase y Scopus mediante las palabras clave "mandibular stability", "skeletal stability", "mandibular advancement", "sagittal split osteotomy", "sagittal split ramus osteotomy", "class II", "class III" y "distraction osteogenesis", relacionadas entre sí con los términos booleanos AND, OR y NOT. También se incluyeron los términos MeSH "mandibular advancement" y "Sagittal Split Ramus Osteotomy". Paralelamente se realizó una búsqueda manual en las revistas AJODO, BJOMS, JOMS y EJO. Resultados y discusión: Se seleccionaron 29 artículos: 24 estudios observacionales analíticos, 2 revisiones sistemáticas y 3 ensayos clínicos aleatorizados. El avance mandibular mediante osteotomía sagital de rama mandibular es estable. No obstante, se debe tener en cuenta la existencia de múltiples factores pre e intraquirúrgicos que podrían generar recidiva del tratamiento.


ABSTRACT: Introduction: The class II skeletal anomaly has a 16-22,5% prevalence worldwide. When class II patients undergo mandibular advancement through Bilateral Sagittal Split Osteotomy (BSSO), they can present a postoperative instability, evidenced as a relapse. Objective: To describe the stability of mandibular advancement through BSSO in skeletal class II patients. Materials and method: An electronic search was performed in the databases PubMed, EBSCO, The Cochrane Library, Tripdatabase and Scopus using the keywords "mandibular stability", "skeletal stability", "mandibular advancement", "sagittal split osteotomy", "sagittal split ramus osteotomy", "class II", "class III" and "distraction osteogenesis", related to each other with the Boolean terms AND, OR and NOT. Also "mandibular advancement" and "Sagittal Split Ramus Osteotomy" MeSH terms were included. In parallel, a manual search in the journals AJODO, BJOMS, JOMS and EJO was performed. Results and discussion: 29 articles were selected: 24 analytic observational studies, 2 systematic reviews and 3 randomized clinical trials. Mandibular advancement through BSSO is stable. However, multiple pre and intraoperative factors that could cause a treatment relapse must be taken into account.
