Abstract. The increase in the number of patients with head and neck tumors in Russia in 2019 was 10.7% higher than in 2014. Radical surgical interventions are the main methods of treatment, but their outcomes are associated with impaired facial nerve function.
Aim of this review was to study international and domestic experience and the results of existing methods of surgical correction of the consequences of facial nerve damage after radical surgery in patients with head and neck tumors.
Material and methods. A literature search was conducted in the databases MEDLINE (PubMed), Tripdatabase, Embase, NICE, The Cochrane Library, eLibrary, CyberLeninka, Google Scholar with the inclusion of studies in English and Russian, reporting on the results and methods of surgical corrections. Filters have been applied to the type of articles and the date of publication ― no later than 5 years (from 2016 to 2021).
Results. According to the search query, 1,727 publications were submitted. The search results did not present systematic reviews, meta-analyses, and randomized controlled trials comparing the clinical efficacy and safety of various surgical techniques for facial nerve repair/reconstruction after radical operations. In this regard, the analysis of international experience was based on seven literature reviews and clinical guidelines, as well as publications of clinical cases by domestic and foreign authors.
Conclusions. In modern literature reviews, there are no clear recommendations and standards for surgical treatment of facial nerve injuries. When choosing the tactics of surgical restoration of the facial nerve, an individual comprehensive approach is necessary.
Key words: head and neck tumors, facial nerve damage, facial nerve reconstruction.
