We present a case of midface distraction in a bilateral cleft lip and palate patient. The patient was a 10-year-old who underwent a high LeFort I osteotomy followed by placement of the Rigid External Distraction halo. Distraction was commenced on the fifth postoperative day at a rate of 1 to 1.5 mm per day until a total of 17 mm of maxillary advancement had been achieved. There were no complica...

The first 25 consecutive patients with high occlusal plane angulation, dysfunction, and pain who were treated with temporomandibular joint (TMJ) total joint prostheses and simultaneous maxillomandibular counterclockwise rotation were evaluated before surgery (T1), immediately after surgery (T2), and at the longest follow-up (T3) for surgical movements and long-term stability. Subjective ratings...

We report a case involving a young female patient with severe mandibular retrognathism accompanied by mandibular condylar deformity that was effectively treated with Le Fort I osteotomy and two genioplasty procedures. At 9 years and 9 months of age, she was diagnosed with Angle Class III malocclusion, a skeletal Class II jaw relationship, an anterior crossbite, congenital absence of some teeth,...

Maxillomandibular advancement (MMA) is a surgical option for obstructive sleep apnea (OSA). MMA involves forward-fixing the maxilla and mandible approximately 10  mm via Le Fort I maxillary and sagittal split mandibular osteotomies. We retrospectively reviewed outcomes from 24 consecutive OSA patients who underwent MMA at our institution. MMA resulted in an 83% reduction in the group mean apnea...

Treatment of Class II malocclusion in adolescents has always relied on growth modification. The majority of treatment modalities, such as functional appliances, are directed at stopping or redirecting maxillary growth simultaneously stimulating mandibular growth. On the other hand, in adult patients with severe Class II malocclusions, generally involving extremely deficient mandibles, orthognat...

The aim of our work is to provide maxillofacial surgeons with an integrated osteotomy planning system for complex bone relocations, facilitating a preoperative assessment of functional as well as æsthetic rehabilitation. On this account we try to establish a robust modeling approach based on a histomechanical soft tissue model that reliably predicts the postoperative facial appearance. For two ...

The dental occlusion and alterations in orofacial muscles were studied in 267 patients whose severe anterior open bite had been treated with a Le Fort 1 intrusion osteotomy with or without an advancement sagittal split osteotomy about 6 years ago. Only 17% of those patients showed anterior contact, and 20% had no vertical overlap of mandibular and maxillary central incisors at all. Tongue posit...

Aim: To examine the pharyngeal airway space (PAS) changes in patients with skeletal Class III anomalies treated two different bimaxillary surgery (BMS) techniques. Methodology: A total of 27 (15 females, 12 males) BMS were divided into groups: Group 1 (n=16, mean age: 20.67±2.82 years) consisted who underwent maxillary-mandibular advancement (MMA), and 2 (n=11, 23.87±7.72 maxillary mandibular s...

The purpose of this cephalometric study was to evaluate the craniofacial changes induced by functional treatment of mandibular advancement with special regard to pharyngeal sagittal airway dimensions, tongue and hyoid bone position in subjects with sleep-disordered breathing (SDB) and dentoskeletal Class II malocclusions compared with an untreated Class II control group. 51 subjects (24 female,...
