In France, the main causes for unilateral laryngeal nerve paralysis in the adult patient are surgery and malignant tumors. Most of unilateral laryngeal nerve paralysis following thyroid surgery will recover within the first six postoperative months. At the time of unilateral laryngeal nerve paralysis, swallowing impairment and dyspnea occur in around 30% and 5% of cases, respectively. In the face of a unilateral laryngeal nerve paralysis occurring without a history of trauma of surgery, the main paraclinical examination to perform is a computed laryngeal nerve examination analyzing the whole length of the nerve involved. Speech therapy efficiency is related to the degree of severity of the symptoms related to unilateral laryngeal nerve paralysis. In the vast majority of cases, laryngeal medialization approaches improve dysphonia and swallowing impairment related to unilateral laryngeal paralysis, but not dyspnea.

Introduction. One of the most common postoperative complications of thyroid surgery is unilateral abduction paralysis of the larynx, resulting from traumatization of the reccurent laryngeal nerves. The prevalence ofthis complication varies in different limits, however, the average prevalence rate according from 0.3–13.2 % ofall performed thyroid surgery.The purpose of the work is to evaluate the ... [Show full abstract] effectiveness of non-selective reinnervation of the larynx withunilateral laryngeal paralysis in order to correct the dysphonic and dysphagic syndromes.Methods. The results of surgical and conservative treatment of abduction unilateral paralysis of the larynxwith the aim of correcting the dysphonic and dysphagic syndromes are analyzed. For the study, the main (46)and control (13) patient groups were taken. In the main group, all patients underwent non-selective reinnervation of the larynx with the imposition of anastomosis RLN-ansa cervicalis, in the control group — conductingconservative treatment in accordance with generally accepted protocols. Results were compared on the VHI-30and EAT-10 scales before and after treatment.Results. It was established that the implementation of non-selective reinnervation of RLN-ansa cervicalis led to the elimination of clinical manifestations of dysphonia in 45 patients out of 46 operated, dysphagicsyndrome in 34 out of 35. In the control group, these indicators were significantly lower: in 9 patients outof 13 there were signs of dysphonia, in 6 with 10 signs of dysphagia. The effectiveness of treatment of dysphagicand dysphonic syndromes in the main group was 97.8 % and 97.1 % according to the results of the VHI-30 andEAT-10 scales, compared with the control group of 30.8 % and 46.1 %.Findings. Non-selective reinnervation of the larynx with abduction unilateral laryngeal paralysis is ahighly effective method of treating dysphonic and dysphagic syndromes, the implementation of which led to animprovement in the quality of life of patients, the latter acquiring sufficient voice and swallowing function
