Sarikov R, Juodzbalys G - J Oral Maxillofac Res (2014)

Bottom Line: Articles from January 2009 to June 2014 were searched.Articles were analyzed on men and women.The influence of lower third molar extraction (especially impacted) on the inferior alveolar nerve was clearly seen.

ABSTRACT

Objectives: The purpose of this study was to systematically review the comprehensive overview of literature data about injury to the inferior alveolar nerve after lower third molar extraction to discover the prevalence of injury, the risk factors, recovery rates, and alternative methods of treatment.

Material and methods: Literature was selected through a search of PubMed electronic databases. Articles from January 2009 to June 2014 were searched. English language articles with a minimum of 6 months patient follow-up and injury analysis by patient's reporting, radiographic, and neurosensory testing were selected.

Results: In total, 84 literature sources were reviewed, and 14 of the most relevant articles that are suitable to the criteria were selected. Articles were analyzed on men and women. The influence of lower third molar extraction (especially impacted) on the inferior alveolar nerve was clearly seen.

Conclusions: The incidence of injury to the inferior alveolar nerve after lower third molar extraction was about 0.35 - 8.4%. The injury of the inferior alveolar nerve can be predicted by various radiological signs. There are few risk factors that may increase the risk of injury to the nerve such as patients over the age of 24 years old, with horizontal impactions, and extraction by trainee surgeons. Recovery is preferable and permanent injury is very rare.

Mentions: According to the PRISMA guidelines [19], an electronic search was conducted using MEDLINE (PubMed) to locate articles concerning IANI after M3 extraction. The keywords used for the search were: “INFERIOR ALVEOLAR NERVE INJURY THIRD MOLAR”, “INFERIOR ALVEOLAR NERVE THIRD MOLAR”, “INFERIOR ALVEOLAR NERVE DAMAGE THIRD MOLAR”, “INFERIOR ALVEOLAR NERVE PARESTHESIA THIRD MOLAR”, ”INFERIOR ALVEOLAR NERVE DYSESTHESIA THIRD MOLAR”, “PERMANENT INFERIOR ALVEOLAR NERVE INJURIES THIRD MOLAR”. The search was restricted to English language articles published from January 2009 to June 2014. The search results revealed a high number of articles (1,251); however, a significance number of the shown articles were not related to the topic and were excluded according the exclusion criteria. Selection and filtration were done in order to know which articles were more suitable for the research. In the beginning, the titles of the article were read, and if the title fit the general idea of the research, the abstract of the article was read. After the abstract reading and after ensuring that the article provided the necessary information for the research, the entire article was read. The bibliographies of the selected articles were also manually searched. Figure 1 illustrates the flow diagram of the comprehensive literature review.
