Lingual nerve protection during surgical removal of lower third molars. A prospective randomised study

Aim: Study of the causes that may contribute to complications during and after tooth extraction to justify treatment and prevention measures. materials and methods: A retrospective analysis of the content of ambulatory cards and protocols of operations of 168 patients for the period from 2016 to 2018 and evaluation of the results of personal work for 2018-2020 related to surgical interventions in 134 patients which removed the third lower molars. Results: According to the retrospective material, damage to the inferior alveolar nerve was found in 5.9% of cases, lingual nerve – in 3.3% of cases, the prevalence of alveolitis with simple removal was 16.3% of cases, at difficult and surgical removal – 3.9% of cases. The application of our proposed treatment and prevention complex allowed to reduce their rates to 3.1%, 2.3%, 8.0% and 3.8% of cases, respectively. Risk factors for complications have been identified. Conclusions: when planning the method of surgical removal of third lower molars it is necessary to take into account the probability of its intimate location in relation to inferior alveolar nerve and lingual nerve. The presence of focus of destruction with signs of acute or exacerbation of chronic inflammation in the periodontal bone tissue of the causative tooth is a risk factor for alveolitis and an indication for the appointment of treatment and prevention in the preoperative period, even with simple removal.

Background: The aim of this prospective study was to determine the incidences of inferior alveolar nerve and lingual nerve deficit following surgical removal of impacted mandibular third molars and to evaluate the risk factors responsible for these postoperative neurosensory deficits.Methods: A total of 80 patients who reported to department of oral and maxillofacial surgery, Meenakshi Ammal Dental College, Chennai, Tamil Nadu, India requiring surgical removal of impacted mandibular third molar were included in this cross-sectional study. Standard surgical procedure was performed. All patients were reassessed one week post-surgery. Subjectively reported altered sensations were recorded and objective assessments were performed with light touch test, two-point discrimination threshold and pin-pick pain threshold. The collected data was analyzed using the chi square test to find out any clinical relevance.Results: There was no inferior alveolar nerve related neurosensory deficits and 6 (7.5%) resulted in lingual nerve related neurosensory deficits. The incidence of LN deficit for mesioangular, horizontal, distoangular was 1.3%, 3.8% and 2.5% respectively. Type of impaction assumed a mild statistical significance (p = 0.050).Conclusions: This study highlights the importance of careful preoperative clinical and radiographic assessment of patients where third molar surgery is planned. The surgical technique of third molar removal is also likely to have great impact on the outcome.

Mandibular Third Molars

Surgical removal of impacted mandibular third molars are the most commonly performed minor surgical procedures by maxillofacial surgeon. If not treated can lead to few complications like pericoronitis, root resorption of second molar, caries of second molar, cyst and tumours can arise from them. The common complications include swelling, hematoma, trismus and lingual nerve injuries. In this article 1000 cases of various types impactions were surgically operated and assessment of lingual nerve injury was done.
