The ESTMJS (European Society of Temporomandibular Joint Surgeons) Consensus and Evidence-Based Recommendations on Management of Condylar Dislocation.

Although condylar dislocation is not uncommon, terminology, diagnostics, and treatment concepts vary considerably worldwide. This study aims to present a consensus recommendation based on systematically reviewed literature and approved by the European Society of TMJ Surgeons (ESTMJS). Based on the template of the evidence-based German guideline (register # 007-063) the ESTMJS members voted on 30 draft recommendations regarding terminology, diagnostics, and treatment initially via a blinded modified Delphi procedure. After unblinding, a discussion and voting followed, using a structured consensus process in 2019. An independent moderator documented and evaluated voting results and alterations from the original draft. Although the results of the preliminary voting were very heterogenous and differed significantly from the German S3 guideline (p < 0.0005), a strong consensus was achieved in the final voting on terminology, diagnostics, and treatment. In this voting, multiple alterations, including adding and discarding recommendations, led to 24 final recommendations on assessment and management of TMJ dislocation. To our knowledge, the ESTMJS condylar dislocation recommendations are the first both evidence and consensus-based international recommendations in the field of TMJ surgery. We recommend they form the basis for clinical practice guidelines for the management of dislocations of the mandibular condyle.

Study of condylar positional changes after sagittal split osteotomy for mandibular advancement: A prospective cohort study.

PURPOSE: To analyse the possible morphologic and positional changes of the mandibular condyles after orthognathic surgery. MATERIAL AND METHODS: A prospective cohort study was performed. Patients with mandibular retrognathism were surgically treated to advance the mandible. The study group included seventeen patients (34 condyles) treated with sagittal split osteotomies alone (4 patients) or in combination with maxillary osteotomies (13 patients). Only condyles located on the mandibular side that advance during surgery were studied, therefore only 25 condyles entered this prospective study. Beside it, a group of 6 patients undergoing maxillary surgery as only procedure, maxillary group, was also studied to determinate the influence of maxillary surgery on condylar displacement. Computed tomographies and lateral cephalometric radiographs were performed two weeks before surgery and one year after the surgical procedures. Different variables which analyse the position and morphology of the mandible were studied. The data obtained were analysed statistically by computing R2 values. RESULTS: In the maxillary group they were small displacements in magnitude and not significant. In the study group, 8 condyles showed morphological changes with alteration on reference points. In the remainder 17 condyles different displacements were noted after surgery. Several of these positional changes were predictable and did not affect postoperative mandibular stability. CONCLUSIONS: condylar displacements that occur after sagittal split osteotomies for mandibular advancement show significant correlation with the degree of mandibular advancement and can be defined by mathematical formulae. Maxillary osteotomies do not seem to influence condylar position when bimaxillary procedures take place.

Patients' perception of recovery after third molar surgery following postoperative treatment with moxifloxacin versus amoxicillin and clavulanic acid: a randomized, double-blind, controlled study.

PURPOSE: To analyze the impact of the postoperative administration of moxifloxacin (MXF) on oral function and quality of life after third molar (TM) surgery. MATERIALS AND METHODS: A single-center, prospective, randomized, double-blind, controlled clinical trial was designed. The study population consisted of 100 patients who underwent impacted TM extractions. Patients were distributed into 2 groups of 50 individuals each. Postoperatively, one group was administered MXF (400 mg/24 hours for 5 days); the positive control group received amoxicillin and clavulanic acid (AMX-CLV) (500/125 mg/8 hours for 5 days). Follow-up was performed for 7 postoperative days, during which the patient recorded information on pain, the use of rescue analgesia, undesirable effects of the medication, difficulty in speaking, difficulty in chewing, diet consistency, difficulty performing oral hygiene, asthenia, time in bed, going out of the house, and returning to work. RESULTS: The administration of MFX was significantly associated with headache, and AMX-CLV was significantly associated with diarrhea. Greater difficulty in chewing and performing oral hygiene was observed in the AMX-CLV group compared with the MXF group. The percentage of patients who tolerated a diet of normal consistency was significantly higher in the MXF group compared with the AMX-CLV group. During the first 4 days of follow-up, the percentage of patients who returned to work was significantly higher in the MXF group than in the AMX-CLV group. CONCLUSIONS: Moxifloxacin shortens the period of postoperative recovery in terms of oral function and return to work. Therefore, MXF could be a useful option in TM surgery when antibiotics are indicated, particularly if patients are allergic to beta-lactams, their oral flora is resistant to macrolides, or they are intolerant of either of these antibiotics.
