Facial soft tissue response to maxillo-mandibular advancement in obstructive sleep apnea syndrome patients

Abstract

BackgroundFacial profile soft tissue changes after orthognathic surgery are crucial for surgery success. This retrospective study evaluated soft tissue changes after maxillo-mandibular Advancement and counter clockwise rotation surgery in obstructive sleep apnea syndrome patients.MethodsThirty-seven obstructive sleep apnea syndrome patients (30 male, 7 female, mean age 35.8 years) whose underwent maxillo-mandibular-advancement and counter clockwise rotation surgery were studied after two intervals of time, presurgical, postsurgical and follow up (1–6 months and 1–5 years) using Dolphing Imaging Software. The soft tissue changes that were evaluated included Glabela, nasal projection, Subnasale, superior incisor, superior lip, inferior incisor, inferior lip, soft tissue B’ point and soft tissue Pogonion. Points were measured from true vertical line on the horizontal plane according to Arnett soft tissue profile analysis. Wilcoxon test was applied for testing differences between T0 (pre surgical), T1 (1–6 months postsurgical) and T2 (1–5 years postsurgical).ResultsCephalometric points changed to more aesthetic parameters. The largest advancements took place in the mandible, due to patients’ anatomic characteristics and treatment planning, whose were measured at cephalometric points B′ (9,05 mm) and Pog’ (11,92 mm) at T0–T2. In all patients aesthetics goals were accomplished.ConclusionThis study showed that maxillo-mandibular advancement and counter clockwise rotation surgery is an effective treatment for OSAS, with good aesthetic results.

Effects of maxillomandibular advancement on respiratory function and facial aesthetics in obstructive sleep apnoea patients with versus without maxillomandibular deficiency

“…These findings are consistent with those of previous studies. 27,28 A finding of interest is that when examining the lip position to Eline, 29 the protrusion of the upper lip and lower lip increased significantly after MMA, but the increase was less than the increase relative to TVL. This is because the increased prominence of the chin can balance the lip protrusion relative to the E-line.…”

Face in the Hijazi Idioms: What Does It Reveal?

“…There have been numerous ongoing Western studies made on the human face. These include studies related to medicine (Cifuentes et al 2017), psychology (Ekman 1978), anthropology (Ketisikist 2003), neuroscience (Bruce & Young 1986), psychology (Tickle 2003), linguistics (Wierzbicka 1993and 2000, Kidron & Kuzar 2002, Vainik 2011, Yu 2009, Marmaridou 2011, to name only a few. As for Arabic, classical studies include medicine, (Note 1) physiognomy (Note 2) and rhetoric as summarized in (Ateeq 1985).…”
