Влияние неселективной реиннервации гортани на основные характеристики голоса

Влияние неселективной реиннервации гортани на основные характеристики голоса

Abstract

The possibility and long-term results of non-selective surgical reinnervation by primary and delayed anastomosis of recurrent laryngeal nerve (RLN) with the one of the peripheral neck nerve (proximal RLN part, main part of ansa cervicalis, nerve-donor) in unilateral laryngeal paralysis have been investigated. At preoperative and postoperative stages we studied indirect laryngoscopy, videolaryngoscopy, spectral analysis of voice (fundamental frequency, intensity and harmonic-to-noise ratio (HNR), the maximum phonation time (MPT), patient's self-assessment of voice quality has been examined. Results. The anastomosis of the RLN was performed in 95 patients, who were in the main group (53 patients with anastomosis ansa cervicalis RLN, 34 patients with anastomosis RLN RLN and 8 with anastomosis RLN nerve-donor RLN).The postoperative average follow-up was 12.0 ± 1.8 months and the median time to the first indirect evidence of reinnervation -4.5 ± 2.9 months, which were observed in all patients of the main group: the emergence of vocal fold tone, reducing the size of the glottis during phonation (especially at the anastomosis ansa cervicalis RLN) from 2.25 ± 0.86 mm to 0.35 ± 0.17 mm. Acoustic analysis showed the most effective reinnervation by the anastomosis ansa cervicalis RLN, with change of HNR from 12.0 ± 3.7 dB to 24.0 ± 2.4 dB, MPT from 7.00 ± 1.22 s to 16.00 ± 3.52 s (p < 0.01). The analysis of subjective psychosocial self-assessment of phonation showed the improvement in all subgroups of the main group.

Исследовались возможность и отдаленные результаты неселективной хирургической реиннервации первичным и отсроченным анастомозом возвратного гортанного нерва (ВГН) с одним из периферических нервов шеи (проксимальный фрагмент ВГН, основная ветвь ansa cervicalis, нерв-донор) при односторонних параличах гортани. На предоперационном и послеоперационном этапах проводились непрямая ларингоскопия, видеоларингоскопия, спектральный анализ голоса (основная частота, интенсивность и соотношение гармоника/шум (СГШ)), максимальное время фонации (МВФ), обследована субъективная самооценка пациентом качества голоса. Результаты. Анастомоз ВГН был выполнен 95 пациентам, которые составили основную группу (53 пациента с анастомозом аnsa cervicalis ВГН, 34 пациента с анастомозом ВГН ВГН и 8 с анастомозом ВГН нерв-донор ВГН). Средний послеоперационный период наблюдения составил 12,0 ± ± 1,8 месяца, а среднее время до первых косвенных признаков реиннервации 4,5 ± 2,9 месяца. Эти признаки наблюдались у всех больных основной группы: появление тонуса голосовой складки, уменьшение размера голосовой щели при фонации (особенно при анастомозе аnsa cervicalis ВГН) от 2,25 ± ± 0,86 мм до 0,35 ± 0,17 мм. Акустический анализ показал наиболее эффективную реиннервацию анастомозом аnsa cervicalis ВГН с изменением СГШ от 12,0 ± 3,7 dB до 24,0 ± 2,4 dB, МВФ от 7,00 ± ± 1,22 с до 16,00 ± 3,52 с (р < 0,01). Анализ субъективной психосоциальной самооценки голосообразования показал улучшение во всех подгруппах основной группы.
