[The change of objective parameters of voice after laryngeal reinnervation]

Possibilities and late results of nonselective surgical reinnervation, using formation of primary or deferred anastomosis of n. laryngeal recurrence (NLR) with one of cervical peripheral nerves (proximal fragment of NLR, the main branch of cervical loop - ansa cervicalis, nerve-donor) in a one-sided laryngeal paralysis, were studied up. Preoperatively and postoperatively the indirect laryngoscopy, videolaryngoscopy, the voice spectral analysis (main frequency, intensity and the rate harmonics-noise RHN, maximal period of phonation--MPP) were accomplished, subjective selfestimation by a patient of the voice quality (VHI-30) was done. Anastomosis with NLR was formatted in 95 patients, including 53--with cervical loop, in 34 - NLR - NLR, 8 - NLR - nerve donor). Postoperative follow-up have constituted (12 +/- 1.8) mo at average, the period up to occurrence of the first indirect signs of laryngeal reinnervation- (4.5 +/- 2.9) mo, were observed in all the patients: occurrence of the vocal plica tone, reduction of the vocal fissure dimensions while phonation (peculiarly in anastomosis of NLR with cervical loop)--from (2.25 +/- 0.86) to (0.35 +/- 0.17) mm. In accordance to data of acoustic analysis, reinnervation is mostly effective in anastomosing of NLR with cervical loop, RHN increased from (12 +/- 3.7) to (24 +/- 2.4) (see symbol) MPP--from (7 +/- 1.22) to (16 +/- 3.52) c (p < 0.01). Improvement in all subgroups of the main group was noted while performing analysis of subjective psychosocial selfestimation of the voice formation.
