Abstract
PURPOSE OF REVIEW Fractures of the mandibular angle are surgically challenging with high rates of postoperative complications. Among established fixation techniques for these injuries, Champy's tension band approach with miniplate fixation has held prominence. Rigid fixation, using two plates, also remains commonly used. More recently, geometric ladder plates, which confer greater three-dimensional stability have been developed to overcome the shortcomings of conventional fixation approaches. Herein, we aim to summarize the recent evidence surrounding the use of ladder plates and offer our own opinion for optimal treatment of these fractures. RECENT FINDINGS In high-powered studies, the rates of hardware failure, malocclusion, and malunion are lower among cohorts managed with ladder plates relative to miniplate groups. Rates of infection and paresthesia remain similar. Ladder plates have also been shown to decrease operative time in preliminary study. SUMMARY Ladder plates show superiority to miniplate approaches across several outcomes. However, the relatively larger strut plate constructs may not be necessary for minor, uncomplicated fractures. It is our belief that reasonable outcomes may be achieved with either approach depending on surgeon experience and comfort with the given fixation technique.

Abstract
INTRODUCTION The goal of mandibular fracture treatment is to restore static and dynamic occlusal functions. Open reduction and internal fixation (ORIF) of these fractures can be associated with an intraoperative and/or postoperative maxillo-mandibular fixation (MMF). The aim of this study was to analyse the use of perioperative MMF and its effects on occlusal outcomes in the management of mandibular fractures. MATERIAL AND METHODS This multicentric prospective study included adult patients with mandibular fractures treated with ORIF. The following data were collected: age, gender, pre-trauma dental status (dentate, partially dentate), cause of injury, fracture site, associated facial fractures, surgical approach, type of ORIF (rigid, non-rigid or mixed), thickness and number of plates, modality of intraoperative MMF (arch bars, self-tapping and self-drilling screws [STSDSs], manual, other) and duration of postoperative MMF. The primary outcome was malocclusion at 6 weeks and 3 months. Statistical analyses were performed with Fisher's exact test or chi-square test, as appropriate. RESULTS Between 1 May 2021 and 30 April 2022, 336 patients, 264 males and 72 females (median age, 28 years) with mandibular fractures (194 single, 124 double and 18 triple fractures) were hospitalized. Intraoperative MMF was performed in all patients. Osteosynthesis was rigid in 75% of single fractures, and rigid or mixed in 85% and 100% of double and triple fractures, respectively. Excluding patients who underwent manual reduction, postoperative MMF (median duration, 3 weeks) was performed in 140 (64%) patients, without differences by type or number of fractures (p > 0.05). No significant difference was found in the incidence of malocclusion in patients with postoperative MMF (5%, 95% confidence interval [CI], 2-10%) compared to those without (4%; 95% IC, 1-11%) (p > 0.05). CONCLUSION Postoperative MMF was performed in more than half of the patients despite adequate fracture osteosynthesis, with wide variability amongst centers. No evidence of a reduction in the incidence of postoperative malocclusion in patients treated with postoperative MMF was found.

Does Dynamic Intermaxillary Fixation With Elastics Improve Outcomes Following Unilateral Condylar Fracture? J Oral Maxillofac Surg 2020; 79:192-199. [PMID: 33011163 DOI: 10.1016/j.joms.2020.08.040] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2020] [Revised: 08/28/2020] [Accepted: 08/28/2020] [Indexed: 11/23/2022]
Abstract
PURPOSE The use of rigid versus semi-rigid intermaxillary fixation (IMF) following subcondylar fractures is controversial. This study aims to investigate whether the "dynamic" elastic fixation technique improves the outcomes, compared to the rigid fixation technique for the treatment of displaced subcondylar fractures in adults. MATERIALS AND METHODS This nonblinded randomized clinical trial was performed on adult patients with unilateral displaced mandibular subcondylar fractures. Patients were randomly allocated into two groups (n = 17). The primary predictor variable was wire versus elastic IMF. Changes in primary (mouth opening) and secondary (other clinical and radiological) outcomes were recorded. Data were analyzed with the t test and Mann-Whitney test with SPSS software version 20. P-value < .05 considered as significant. RESULTS In this study 34 patients (with mean age of 33.03 ± 1.79, 23.5% females & 76.5% males) in two groups (Elastics & Wire) followed up to 6 months. The Elastics group showed significant improvement in mouth opening (primary outcome) after 1 month of follow-up, but the differences were not significant at the end of the study. In terms of secondary outcomes, the ramus height shortening compared to the opposite side revealed favorable improvement in the Elastics group in the period of study. The differences between the two groups in the lateral movement and protrusive movement were significant in favor of the Elastics group. The differences in pain, fracture displacement, and midline deviation between study groups were not significant at the end of the study. Just 1 case with malocclusion was observed in the Wire group. Patients were more satisfied with dynamic nonrigid IMF with elastics. CONCLUSIONS The results of this study showed that using the dynamic IMF technique is more tolerable, and patients have better functional and clinical outcomes during and at the end treatment.

A comparison of panoramic radiography and cone beam computed tomography in the detection of osteosynthesis complications in sheep mandibular angle fractures. Oral Surg Oral Med Oral Pathol Oral Radiol 2018; 127:167-174. [PMID: 30415905 DOI: 10.1016/j.oooo.2018.10.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2018] [Revised: 09/26/2018] [Accepted: 10/05/2018] [Indexed: 11/23/2022]
Abstract
OBJECTIVE The aim of this study was to compare the diagnostic efficacy of panoramic radiography (PANO) and cone beam computed tomography (CBCT) in detecting simulated complications of plate osteosynthesis applied to mandibular angle fractures (MAFs). STUDY DESIGN Unfavorable MAFs were created in 100 fresh sheep hemimandibles. Fractures were fixed with 4-hole titanium miniplates and screws. Bone necrosis around the screws, penetration of the screw into the inferior alveolar canal, screw loosening, and plate breakage were simulated. The diagnostic efficacy of the imaging techniques was compared by using intra- and interobserver agreement scores and area under the receiver operating characteristic curve (AUC) values. Examination time (ET), confidence scores (CS), and planar preference (PP) in CBCT evaluation were assessed. RESULTS Intra- and interobserver agreement scores varied between 0.61 and 0.91. AUCs for screw penetration into the inferior alveolar canal and screw loosening were significantly higher in CBCT than in PANO (P < .05). CBCT presented significantly higher ET and CS values compared with PANO (P < .05). PP showed significant differences among types of complications (P < .05). CONCLUSIONS PANO provided acceptable outcomes in the detection of bone necrosis and broken plates around the screw, but CBCT was more likely to enable detection of all simulated types of complications with higher confidence.

Abstract
Purpose: The purpose was to analyze the clinical course of surgically treated mandibular angle fractures from the viewpoint of routine removal of the plate because these fractures are associated with high rates of complications and plate removal. Subjects and Methods: The subjects were 40 patients with unilateral mandibular angle fracture, which was intraorally reduced and principally fixed with a single miniplate on the external oblique ridge. The third molar in relation to the fracture line was extracted in seven patients during the surgery. Clinical course was evaluated in terms of removal of the plate, preservation of the third molar and complications. Results: One patient showed a wound infection postoperatively, and two patients developed pericoronitis during the follow-up. These were managed with medication and local irrigation. One patient with a preserved third molar did not make a required visit and was lost from the follow-up. Removal of the plates was performed in 39 patients after confirmation of good fracture healing, mostly within a year. Twenty-four of 32 preserved third molars were simultaneously extracted. These procedures were generally performed under local anesthesia on an outpatient basis, and they did not cause any complications. Conclusions: Routine removal of the plate after surgical treatment for mandibular angle fractures, simultaneously with extraction of the third molar if indicated, may be beneficial to avoid complications related to the plate and the third molar later in life.
