Introduction: The zygomaticomaxillary complex (ZMC) fractures are the second most common fractures affecting the midfacial skeleton. Neurosensory disturbances of the infraorbital nerve are one of the most common signs of ZMC fractures. The aim of the study was to evaluate the neurosensory recovery of the infraorbital nerve and its effect on the quality of life (QoL) following open reduction and internal fixation of ZMC fractures. Methods: Thirteen patients clinically and radiologically diagnosed with unilateral ZMC fractures with neurosensory deficits of the infraorbital nerve were enrolled for this study. All patients were assessed presurgically for neurosensory deficits of the infraorbital nerve using the various neurosensory tests, followed by open reduction with two-point fixation under general anaesthesia. The patients were followed up at one, three and six months postoperatively to evaluate the recovery of neurosensory deficits. Results: Recovery of tactile and pain sensation was relatively complete in 84.62% and 76.92% of patients respectively by the end of six months postoperatively. The spatial mechanoreception of the affected side improved significantly. 61.54% of patients led an excellent QoL six months postoperatively. Discussion: The majority of the patients with ZMC fractures and neurosensory deficits of the infraorbital nerve, when treated with open reduction and internal fixation, have complete recovery of the neurosensory deficits by the end of six months postoperatively. However, some patients may continue to experience some long-term residual deficits, which can affect the patient’s QoL.
Background: Effectuating adequate width of keratinized tissue (WKT) can lead to a healthy and stable implant/soft tissue interface which is important for the long term success of the implant. The use of free gingival grafts (FGG) for widening the WKT around dental implants increases the amount of attached gingival tissue and prevents clinical attachment loss. Aim: The aim of the study was to assess the ability of FGG to create a healthy implant/soft tissue interface. Methods and Material: A total of 10 edentulous sites in 10 patients with inadequate keratinized tissue indicated for replacement of missing teeth were treated. An implant was placed in edentulous sites and the keratinized tissue was augmented using FGG at the second stage of implant surgery. WKT was recorded at baseline, 3rd month and 6th month post-operatively. Plaque index (PI), gingival index (GI), probing depth (PD) and papillary index (PPI) and were recorded at 3 and 6 months post-operatively to evaluate the health of peri-implant tissues. Paired t-test was used for standard deviation and the level of significance was taken as 5% ( P < 0.05). Results: The WKT at 3 (3.2±1.61mm) and 6 months (3±1.56 mm) compared to the baseline was statistically significant ( P = 0.034). The other parameters PI, GI, PD, PPI showed no clinical significance from 3 and 6 months ( P > 0.05). Conclusions: Augmentation of FGG created a significant gain in the WKT which resulted in a healthy implant/soft tissue interface.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
