Obstructive sleep apnoea (OSA) results from the recurrent collapse of the upper airway during sleep. Nasal abnormalities influence the stability of the pharynx. The aim of this study was to evaluate the volumetric and anatomical changes of the nasal cavity in patients with OSA. The Nasal Obstruction Symptom Evaluation (NOSE) scale was used to grade nasal obstruction. Sleep-related breathing disorders were evaluated by polysomnography. The nasal airway volume was obtained from computed tomography scans through volumetric reconstruction of the nasal airway...

Dislocation of the temporomandibular joint, which represents 3% of all dislocated joints reported in the body, occurs when the mandibular condyle is displaced anteriorly beyond the articular eminence. Although anterior dislocation of the mandibular condyle is well documented in the literature, superior, lateral, and posterior dislocation of the condyle is rare. Only a few reports documenting superolateral dislocation with anterior mandible fractures have been published in the past. However such dislocations without any associated fractures are even rarer...

Aglossia is a rare congenital abnormality, often associated with micrognathia and limb defects. Situs inversus totalis is also a rare congenital abnormality, defined as a mirror-image reversal of all the asymmetric organs of the thorax and abdomen. The concurrence of these two abnormalities has only been reported in eight similar cases in the literature. Although micrognathia and malocclusion were observed in all of these cases, few treatments were performed for the patients' dentofacial deformities. This report describes the case of a 7-year-old boy suffering from micrognathia, aglossia, and situs inversus totalis simultaneously, and the treatment for his micrognathia by mandibular symphyseal midline distraction osteogenesis, guided by virtual surgical planning and a three-dimensional printed surgical template...

This study aimed to evaluate whether pre-emptive analgesia modifies the tissue expression of tumour necrosis factor alpha (TNF-α) and interleukin 1 beta (IL-1β), and whether there is an association with postoperative surgical outcomes. A triple-blind, randomized, placebo-controlled study of patients undergoing mandibular third molar removal was performed. Volunteers were allocated randomly to receive etoricoxib 120 mg, ibuprofen 400 mg, or placebo 1h before surgery. Twenty-four surgical sites per group were required (95% confidence level and 80% statistical power)...

Intraoperative navigation is a helpful tool in complex anatomical regions or procedures. The mobility of the mandible in relation to the skull base limits the use of navigation tools on the lower jaw if the reference device is installed on the forehead. A new workflow that allows navigation-assisted sagittal split osteotomy in orthognathic surgery using a separate non-invasive mandibular registration technique has been developed. An evaluation of accuracy in different anatomical regions and with different registration techniques was performed on skull models and skulls with movable mandibles...
