Assessment of the Relationship Between the Recovery of Maximum Mandibular Opening and the Maxillomandibular Fixation Period After Orthognathic Surgery

ABSTRACT Objectives: to identify the main doubts regarding the immediate postoperative care of patients with orofacial clefts undergoing orthognathic surgery. Methods: cross-sectional, quantitative study, developed in a public and tertiary hospital, between November 2017 and May 2018. Data collection occurred through interviews during the preoperative nursing consultation. An instrument was used to describe doubts, which later were grouped according to the subject. Results: 48 patients participated. The doubts referred to sun exposure (56%), food/mastication (48%), the relationship between intermaxillary block-breathing-vomiting (48%), oral hygiene (31%), physical activity restriction (27%), nasopharyngeal cannula, removal of surgical stitches, hospitalization time and speech/communication (23%), bleeding, cryotherapy, facial massage, aesthetic and functional results, healing, edema/ecchymosis, postoperative pain, and changes in facial sensitivity (21%). Conclusions: the doubts were related to food, the period of convalescence, care for the surgical wound, postoperative complications, and medications.

ABSTRACT Objective: To evaluate the pharyngeal airway and maxillary sinus volume changes after mandibular setback surgery combined with maxillary advancement and/or impaction surgery. Materials and Methods: Seventeen Class III skeletal patients (11 females, 6 males) who required bimaxillary orthognathic surgery were selected. Volumetric measurements were performed using cone beam computed tomography (CBCT) scans preoperatively and 3.9 ± 0.87 months postoperatively. All the CBCT scans were assessed and analyzed using MIMICS 14.0 software. Preoperative and postoperative volumes of pharyngeal airway and maxillary sinuses and the relationship between the amounts of surgical movement of the jaws and the above volumes were statistically evaluated. Results: The pharyngeal airway area presented no significant change except for the lower and total pharyngeal airway volumes in males, in whom a significant decrease was observed (4196.27 ± 2061.11 mm3 and 3375.53 ± 3624.67 mm3, respectively). No significant change was observed in the minimal cross-sectional area of the pharyngeal airway. There was a significant decrease in the volume of the maxillary sinuses after the surgery by 3448.09 ± 3315.56 mm3. No correlation was found between the amount of skeletal movement and the change in the volume of pharyngeal airway or maxillary sinuses. Conclusion: There was a significant decrease only for lower and total pharyngeal airway volumes in males and a significant decrease in the volume of the maxillary sinuses.
