Winds of Change in Antibiotic Therapy following Orthognathic Surgery.

Background and objectives: This retrospective cohort study aimed to compare three postoperative antibiotic protocols of different durations on surgical-site-infection (SSI) rates following orthognathic surgery for the correction of jaw deformities. Materials and methods: An analysis on data collected from the medical files of 209 patients who underwent orthognathic surgery between 2010 and 2019 was conducted. The patients were divided into three groups according to the postoperative antibiotic protocol-Group 1 (24 h), Group 2 (2-3 days), and Group 3 (>3 days). Dependent and independent variables were collected, analyzed, and compared between the three groups. Results: Group 1 included 30 patients (14.3%), Group 2 included 123 patients (58.9%), and Group 3 included 56 patients (26.8%). The vast majority of the postoperative antibiotics were amoxicillinand clavulanic acid (87.1%). The duration of the surgery and the use of a feeding tube were significantly different between Groups 1 and 3 (p < 0.001 and p = 0.005, respectively). There was no significant difference in SSI rates between the three groups (p = 0.642). The use of antibiotics beyond the immediate postoperative period provides no increased benefit regarding infection prevention. Conclusions: In young and healthy patients undergoing orthognathic surgery, a 24hregimen of postoperative antibiotics may be sufficient.

Outcome of isolated and combined direct feminization laryngochondroplasty: Our first 20 cases.

This retrospective study describes the surgical outcomes of our first 20 transgender women to undergo feminization thyroid laryngochondroplasty (FLC) by a direct transvestibular FLC (DTV-FLC) approach from December 2019 to October 2023. The medical records of all patients were retrieved and reviewed. Data on the operative, postoperative, and follow-up courses, complications, and functional and cosmetic outcomes were retrieved. The cosmetic results were evaluated by four independent facial plastic surgeons. Thirteen patients underwent DTV-FLC combined with genioplasty or genioplasty with mandibular angle reduction and seven underwent isolated DTV-FLC. DTV-FLC was feasible in all planned cases. Complications (skin flap perforation, thyroid cartilage fracture, mental hypoesthesia, hematoma, dehiscence of the vestibular incision, vestibular scar adhesions, and anemia) were minor and resolved spontaneously. The preoperative grade of thyroid cartilage protrusion was 1.9 ± 0.9 on a scale from 1 to 3. The postoperative cosmetic results of 18 patients were judged as having improved (a score of 2.1 ± 0.8 on a scale from -1 to 3). Eighteen patients were satisfied with the cosmetic result, one was dissatisfied (the revision surgery patient), and one was lost to follow-up. In conclusion, DTV-FTLC is a valid surgical approach for FLC, yielding high patient satisfaction and good cosmetic results.

Vertical Ramus Osteotomy, Is It Still a Valid Tool in Orthognathic Surgery?

The purpose of this study is to evaluate mandibular osteotomy procedures during orthognathic surgery, with an emphasis on the complications of the two leading procedures: intraoral vertical ramus osteotomy (IVRO) and sagittal split osteotomy (SSO). We conducted a retrospective cohort study by extracting the records of patients who underwent either IVRO or SSO procedures during orthognathic surgery in a single center between January 2010 and December 2019. A total of 144 patients were included (median age of 20.5 years, 52 males). The IVRO:SSO ratio was 118:26 procedures. When referring to all surgeries performed, IVRO procedures were associated with shorter hospitalization than the SSO procedures, while the overall durations of surgery and follow-up periods were comparable. In contrast, when referring only to bimaxillary procedures, the duration of the IVRO bimaxillary procedures was significantly shorter than the SSO bimaxillary procedures. There were 53 complications altogether. Postoperative complications consisting of skeletal relapse, temporomandibular joint dysfunction, sensory impairment, and surgical-site infection were significantly fewer in the IVRO group. Both types of osteotomies have acceptable rates of complications. IVRO appears to be a safer, simpler, though less acceptable procedure in terms of patient compliance.

Orthognathic surgery complications: The 10-year experience of a single center.

The retrospective cohort study aimed to assess the incidence and characteristics of these complications in patients who underwent orthognathic procedures. Data on the intraoperative and the postoperative complications were extracted from the patients' medical files. Procedures were further subdivided into single-jaw procedures and bimaxillary procedures. A total of 209 orthognathic procedures were carried out in 190 patients. 184 (88%) were performed to treat angle class III malocclusion, while 25 (12%) aimed to treat class II malocclusion. A total of 94 complication events were observed (44.9% of 209 procedures). 22 of them occurred in single-jaw procedures (28.2% of 78 single jaw operations), and 72 occurred in bimaxillary procedures (55% of 131 bimaxillary operations). When compared regarding the type of complication, complication rates were comparable between the study groups with the exception of late-stage malocclusion. A significant difference (p-value = 0.028) in malocclusion incidences between the bimaxillary and single-jaw groups were observed (9 events, 4.3% and zero events, 0%, respectively). The majority of the complications during and following orthognathic surgical procedures are temporary or minor and require little or no treatment at all.

Knowledge and Associated Factors about Rare Diseases among Dentists in Israel: A Cross Sectional Survey.

Aim: The current study aims to assess levels of knowledge among Israeli dentists about rare diseases with orofacial manifestations, and whether occupational, regional and social factors influence those levels. Materials and Methods: A total of 309 Israeli dentists participated in an online survey that provided basic demographic information pertaining to their knowledge about rare diseases, their clinical experience with rare diseases, what further information they considered necessary, and which sources of information they most frequently utilize. Results: Young age, country of dental education, practicing in both public and private settings, as well as the number of hours allocated to dental studies and the opportunity to acquire information on rare diseases with orofacial manifestations, all seem to affect the level of knowledge. Conclusions: Developments in the field of rare disease are constantly ongoing, and improvements in post-graduate dental studies about them should keep pace. The results of the current study reveal the areas upon which such curricula should focus with respect to dental practitioners.
