RESUMEN
BACKGROUND/AIM: Paediatric maxillozygomatic complex (MZC) fractures are uncommon, and there is a scarcity of data regarding their surgical treatment. The aim of this study was to analyse choices and outcomes of open reduction and internal fixation (ORIF) for MZC fractures among 14 maxillofacial centers around the world. MATERIALS AND METHODS: This multicentric retrospective observational study included patients ≤16 years of age with quadripod MZC fractures treated with ORIF from January 2011 and December 2022. The following data were collected: age, gender, dentition stage (deciduous, mixed, and permanent), cause of injury, type of fracture, surgical approach, site of osteosynthesis (infraorbital rim, zygomaticomaxillary buttress, frontozygomatic, and zygomaticotemporal sutures), material (titanium or resorbable) and number of plates used, and outcome. The minimum follow-up was 6 months. Statistical analyses were performed with Fisher's exact test or chi-squared test, as appropriate. RESULTS: Sixty-four patients (mean age, 12.3 years) with quadripod MZC fractures were included. Seventy-two percent of patients received a single-point fixation. The zygomaticomaxillary buttress was the most common site for fixation, both in single-point and two-point fixation schemes, especially in combination with the frontozygomatic suture. Increasing age was associated with a higher rate of plate removal (p < .001). Postoperative complications included 5 (7.8%) cases of wound infections, 2 (3.1%) infraorbital paraesthesia, 1 (1.6%) ectropion. Residual facial asymmetry was found in 5 (7.8%) patients and was not associated with the type of fixation (p > .05). CONCLUSIONS: This study highlights the possibility of using ORIF, even with a single point of fixation, for the treatment of displaced quadripod MZC fractures in the paediatric population. The zygomaticomaxillary buttress was the preferred site of fixation and allowed for adequate stabilization with no external scars and a low risk of tooth damage. Future prospective studies with long-term follow-up are needed to establish definitive surgical protocols and clarify the surgical decision-making.
RESUMEN
This study evaluated patient's perception of recovery following surgical removal of mandibular third molars (SRM3s) including analyze of potential risk factors associated with impaired convalescent. Patient related parameters combined with preoperative questionnaires including Modified Dental Anxiety Scale, Oral Health Impact Profile-14, and Decayed, Missing, Filled Teeth index were correlated with questionnaires assessing pain, swelling, trismus, sick leave, social and working isolation, physical appearance, eating and speaking ability, diet variations, sleep impairment, impaired sensation of the lip, chin, and tongue, one month following SRM3s. Totally, 412 patients (223 females, 189 males) with mean age of 29.4 years were included. Treatment satisfaction and willingness to undergo similar surgery were reported by 92% and 95%, although 21% reported that the surgery and postoperative period had been worse than expected. Mean days with pain, sick leave, and swelling were 3.6, 2.1, and 3.6, respectively. Preoperative symptoms, dental anxiety level, and prolonged surgical time were associated with increased pain and swelling (P < 0.05). Pell and Gregory classification (I-IIIC) were associated with impaired sensation of the lower lip and chin (P < 0.05). Consequently, results from this study improve the surgeon's ability to predict parameters that predisposed to impaired recovery and neurosensory disturbances following SRM3s.
