Pharyngeal airway space changes after maxillomandibular advancement: a five-year retrospective study
The aim of this study was to compare the alterations in three regions of the airway—nasopharynx, oropharynx, and hypopharynx—in relation to the area of the midsagittal plane, volume, and minimal axial area after maxillomandibular advancement (MMA) surgery. Thirty patients who had undergone MMA surgery were evaluated at four time points: preoperative (T0), immediately postoperative (T1), 1year postoperative (T2), and ≥5 years postoperative (T3).

The surgery first approach (SFA) is a therapeutic strategy used in orthognathic surgery that is constantly evolving. With this approach, the pre-surgical orthodontic treatment can be eliminated, the maxilla and the mandible are surgically repositioned into the desired position, and the therapy is ended with a short orthodontic phase. Several studies have reported that the SFA is an acceptable approach, but postoperative stability is unclear. In this study, a systematic review on the SFA was performed.

Abstract Periodontal disease is a chronic inflammatory disease leading to destruction of periodontal tissues. As a local inflammation, periodontopathic bacterium, pro‐inflammatory mediators and local immune response play pivotal role in the progress of periodontal disease. Besides, cigarette smoke has long been associated with periodontal disease and tooth loss. Autophagy is an intracellular degradation process highly conserved from yeast to humans. As a lysosomal degradation pathway of self‐digestion,...
