Follow-up observation of patients with obstructive sleep apnea treated by maxillomandibular advancement

Effects of maxillomandibular advancement surgery on a skeletal Class III patient with obstructive sleep apnea: A case report

“…e three-dimensional increase in the pharyngeal airway (PA) after the MMA procedure agreed with the previous studies. [1,8,19] According to Holty and Guilleminault, MMA enlarges the PA space by expanding the skeletal framework that the soft-tissue pharyngeal structures and tongue attach to resulting in reduced pharyngeal collapsibility during negative-pressure inspiration, and a statistically significant and clinically relevant reduction in the ESS in all subjects after MMA. [21] Based on surgical success criteria, the results of surgical treatment of OSA are divided into "surgical success" and "surgical cure. "…”

“…[24] e MMA surgical movements were found to be stable with less than 1 mm of relapse during the follow-up period, which was not clinically significant. [8] According to Lee et al surgical advancement of the maxillomandibular complex 10 mm for treatment, OSA remains stable at a mean followup period greater than 2 years and pre-operative orthodontic treatment does not appear to influence skeletal stability. [10] Another study by Conradt et al demonstrated that MMA is successful by cephalometric and PSG investigation, and post-operative success has proved to be stable over 2 years.…”

“…[6] However, recent studies substantiated that the maxillomandibular advancement procedure (MMA) is an effective treatment in improvement of OSA regardless of age, craniofacial anomalies, weight, body habitus, or medical history. [7,8] Continuous positive airway pressure (CPAP) therapy is the first line of treatment for patients with OSA syndrome. e use of CPAP prevents upper airway collapse, relieves symptoms, and decreases cardiovascular events.…”

Cirugía de avance maxilo-mandibular como tratamiento alternativo del Apnea Obstructiva del Sueño: Revisión de Literatura.

“…Las apneas pueden clasificarse en tres tipos según su esfuerzo inspiratorio: Cirugía de avance realizarán en el paciente. 4,8,9,[29][30][31][32][33][34] Para la preparación pre quirúrgica se indica el protocolo de Stanford, el cual divide a la cirugía en dos fases: 9,13,32,33 1. Fase l: consiste en la úvulo palato faríngeo plastia y/o genioplastia.…”

“…Si se desea mejorar el aspecto estético y armonizar el rostro, se puede incluir una mentoplastía de avance. 13,26,34,39,40 Existe evidencia científica suficiente que asegura que tras una cirugía de AMM, se obtendrá un aumento en el volumen de las vías aéreas superiores, mejor circulación de oxígeno y conciliación del sueño. Se consolida que la cirugía de AMM corrige las malformaciones craneofaciales, creando un espacio faríngeo posquirúrgico mayor al prequirúrgico, lo que determina una mejoría en la calidad de vida del paciente ya que disminuyen los episodios de apneas/hipoapneas a corto y largo plazo.…”
