Analysis of the effect of microsuture under self-retaining laryngoscope in surgery for sulcus vocalis
Objective To study the practical effect of microsuture under self-retaining laryngoscope in surgery for sulcus vocalis.Methods 30 patients with sulcus vocalis who voluntarily received autologous fat filling to the vibrating edges of the vocal folds with intraoperative application of microsuture under self-retaining laryngoscope from May 2018 to May 2023 were included as the treatment group.30 patients with sulcus vocalis who underwent conventional surgical treatment(articulation treatment or excision of the scarred mass with significant hyperplasia of the diseased sulcus vocalis,separation of the mucosal flap,and loosening of the adhesive bands without intraoperative microscopic sutures)from May 2015 to May 2018 served as the control group.The vocal fold mucosal recovery and pronunciation quality,visual analog scale(VAS)score of laryngeal vocal ability before and after the surgery,computerized voice analysis index,and voice handicap index score were compared between the two groups.Results The incidence of hoarseness in patients in the treatment group was 23.33%,which was lower than 73.33%in the control group,and the difference was statistically significant(P<0.05).After the surgery,the VAS score of laryngeal vocal ability in the two groups was lower than that before the surgery;the VAS score of laryngeal vocal ability in the treatment group was(1.72±0.98)points,which was lower than(5.23±1.16)points in the control group;the difference was statistically significant(P<0.05).After the surgery,the Jitter value and Shimmer value in both groups were lower than those before the surgery,and the duration of articulation was longer than that before the surgery in both groups;the treatment group had Jitter value of(0.22±0.08)%and Shimmer value of(1.19±0.48)%,which were lower than(1.17±0.32)%and(5.28±0.69)%in the control group;the duration of articulation of(17.95±0.99)s in the treatment group was longer than(8.89±0.76)s in the control group;the difference was statistically significant(P<0.05).After the surgery,the score of voice handicap index in both groups was lower than that before the surgery,and the score of voice handicap index of(6.72±0.98)points in the treatment group was lower than(13.23±1.16)points in the control group.The difference was statistically significant(P<0.05).Conclusion Compared with the traditional surgical treatment,the application of microsuture under the self-retaining laryngoscope in surgery for sulcus vocalis can improve the therapeutic effect of patients with sulcus vocalis,and has high clinical practice value,which is worthy of promotion and application.
