“…Data were collected from a period of August 2014 through March 2020. Patients who underwent isolated mandibular advancement surgery without genioplasty and had a craniocervical angle (N-S-Ba) of less than 5 • for overcoming the variation in head position [16] were included in the study. Exclusion criteria involved patients with craniofacial anomalies, syndromic disorders, OSA, previous history of trauma, or any other orthognathic surgery procedure such as Le Fort I or genioplasty.…”

“…The main limitation of the aforementioned studies has either been related to their small sample size [15,16] or short-term follow-up with a maximum duration of 6 months [12]. To our knowledge, currently no evidence exists evaluating 3D airway changes in a large group of patients with a follow-up of 1 year or more in patients undergoing isolated mandibular advancement.…”

Lack of evidence exists related to the three-dimensional (3D) pharyngeal airway space (PAS) changes at follow-up after isolated bilateral sagittal split osteotomy (BSSO) advancement surgery. The present study assessed the 3D PAS changes following isolated mandibular advancement at a follow-up period of 1 year. A total of 120 patients (40 males, 80 females, mean age: 26.0 ± 12.2) who underwent BSSO advancement surgery were recruited. Cone-beam computed tomography (CBCT) scans were acquired preoperatively (T0), immediately following surgery (T1), and at 1 year of follow-up (T2). The volume, surface area, and minimal cross-sectional area (mCSA) of the airway were assessed. The total airway showed a 38% increase in volume and 13% increase in surface area from T0 to T1, where the oropharyngeal region showed the maximum immediate change. At T1–T2 follow-up, both volumetric and surface area showed a relapse of less than 7% for all sub-regions. The mCSA showed a significant increase of 71% from T0 to T1 (p < 0.0001), whereas a non-significant relapse was observed at T1–T2 (p = 0.1252). The PAS remained stable at a follow-up period of 1 year. In conclusion, BSSO advancement surgery could be regarded as a stable procedure for widening of the PAS with maintenance of positive space at follow-up.

The key to successful orthodontic treatment is the use of a delicate, modern, accurate and scientifically sound method of intervention planning. In addition, it is critical that this method takes into account as many variables as possible that may affect the final result. Given these criteria, the most appropriate for planning orthodontic treatment is cephalometric analysis of lateral teleradiograms, which, however, requires preliminary clinical trials to adapt it to the local population. The aim of the study was to establish the features of cephalometric parameters of the upper and lower jaws, determined according to the COGS method, in Ukrainian young men and young women with orthognathic occlusion depending on the type of face. According to the COGS method, cephalometry was performed for 46 young men (aged 17 to 21) and 72 young women (aged 16 to 20) who belonged in three generations to Caucasian residents of Ukraine and had an orthognathic bite. OnyxCeph³™ software, 3DPro version, Image Instruments GmbH, Germany was used for cephalometric analysis of the upper and lower jaws. Determination of the type of face of young men and young women was carried out according to the values of the morphological index of Garson. Statistical processing of the obtained results was performed in the license package "Statistica 6.0" using non-parametric evaluation methods. The following significant or tendencies of differences between linear and angular parameters of the upper and lower jaws were found between young women with different face types: in young women with a very wide face type – lower values of ANS-Me distance and N-A-Pog, MP-HP angles (compared to other types face) and Ar-Go-Gn (compared to medium and narrow face types), as well as larger values of the distances N-B and N-Pog (compared to other face types); in young women with medium face type – smaller the values of the distances N-A (compared to other face types), N-B and N-Pog (compared to wide and narrow face types), Go-Pog (compared to very wide face type), A-B (compared to a wide face type), as well as larger values of the distance B-Pog and angles MP-HP and Ar-Go-Gn (compared to a wide face type); representatives with a narrow face type have higher values of the distances N-ANS (compared to other face types), B-Pog (compared to very wide and wide face types), PNS-N (compared to a wide face type). The following significant or tendencies of differences between linear and angular indicators of the upper and lower jaws were found between young men with different face types: representatives with very wide face type have higher values of N-B, N-Pog, ANS-PNS distances (compared to average face type), Ar-Go (compared to wide and medium face types), A-B (compared to medium and narrow face types) and N-A (compared to narrow face types), as well as smaller MP-HP angle values (compared to other face types); representatives with a narrow face type have larger values of PNS-N (compared to other face types) and N-ANS (compared to very wide and wide face types), as well as smaller values of N-A-Pog angle (compared to average face type); representatives with medium face type have only smaller values of the ANS-PNS distance (compared to wide face type). Young men with different face types also have larger upper linear dimensions of the upper and lower jaws than in young women with different face types; and in young women mainly with narrow and medium face types – angular indicators of the upper and lower jaws.
