Two-dimensional lambda versus three-dimensional delta plates in subcondylar fracture using modified mini retromandibular subparotid approach

Abstract

The objective of this study was to review the orbital fractures managed by our department, especially epidemiological aspects, treatment options and postoperative sequelae. Method: A retrospective review of the orbital fractures treated by the Department of Oral and Maxillofacial Surgery at Middlemore Hospital (Auckland, New Zealand) from 2010 to 2015 was undertaken. Patients were evaluated by age, gender, aetiology, time to surgery, type of reconstructive material used and complications. Results: The most common cause of orbital fracture was interpersonal violence (46%), followed by sporting injuries (25%). Males accounted for 80% of the fractures, with 50% of these being aged between 18 and 30 years old. The most significant complications were ongoing pain and restriction in movement requiring further intervention (6%), infection (3%) and retrobulbar haemorrhage (<1%). Conclusions: In the catchment area for our Hospital, which has a population of approximately 1.5 million, interpersonal violence is the leading cause of orbital fractures. Postoperative complications cannot be evaluated definitively until a few months after surgery.

Open Reduction and Internal Rigid Fixation of Unilateral Displaced Subcondylar Fractures Using a Single Trapezoidal Plate Versus the Traditional Two Miniplates. A Comparative Study.

“…(11,17,18) Regarding mandibular movements concerning the MMO, ipsilateral, contralateral and protrusive excursions, were satisfactory in all patients of both groups and were regained gradually throughout the follow-up intervals with no statistically significant differences and gives a great support and similarity to that reported in the available literature. (34)(35)(36)(37)(38) In the present study, the Mandibular mobility in-dex and the Helkimo index of mandibular dysfunction showed superior results in the trapezoidal plate group compared to the mini-plates group (P=0.303 and P = 0.528 respectively) and both groups showed a significant improvement by time. Although the difference between groups was statistically insignificant, these results provide superiority for the single trapezoidal plate regarding the rigidity of fixation and postoperative fracture stability.…”

“…Comparable results had been achieved by Kozakiewicz et al in 2014 (43) Who evaluated A-shaped plates, another type of three-dimensional plate, and postulated the efficiency of these plates in rigid fixation of high condylar neck and coronoid process fractures and stated that these plates could be used for all levels of condylar fractures. (43) Anchlia et al in 2017 (36) had performed a comparative clinical study to evaluate lambda plates versus delta plates using modified miniretromandibular sub-parotid approach, and the results found no difference between the two plating designs, but the approach was more conservative, tissue sparing, and with less complications.…”
