Abstract:
OBJECTIVE To observe the long-term efficacy of type-Ⅰ thyroplasty under general anesthesia in the treatment of glottal insufficiency caused by unilateral vocal cord paralysis.METHODS A total of 52 patients with unilateral vocal cord paralysis who underwent type-Ⅰ thyroplasty under general anesthesia at Beijing Tongren Hospital from January 2017 to June 2023 were followed up for more than one year to analyze their efficacy.RESULTS All 52 patients underwent surgery successfully under general anesthesia,and hoarseness improved after operation.Coughing caused by drinking water was reduced or disappeared,and the vocal cords moved inward with improved glottal closure.One year after operation,there was no significant change in the position of the affected vocal cords compared to one week after surgery.The visual analog scale(VAS)scores of all patients with voice disorders decreased sequentially before surgery,one week after surgery,and one year after surgery(80.28±13.49 vs.37.78±19.15 vs.26.26±21.29,P<0.05).The preoperative and one-year postoperative voice perception assessment(GRBAS)showed statistically differences in grade(G),rough(R),breathy(B),and asthenia(A)scores(2.70±0.47 vs.1.09±0.66,2.52±0.54 vs.0.85±0.67,2.85±0.36 vs.0.67±0.65,2.74±0.44 vs.0.61±0.80,P<0.05)except for strain(S).Compared with preoperative results,one-year postoperatively showed a significant decrease in jitter and shimmer(4.61±2.61 vs.3.05±2.37,9.52±3.91 vs.7.11±2.78,P<0.05),and a significant prolongation of maximum phonation time(MPT)[(5.87±2.70)s vs.(14.50±4.30)s,P<0.05].No patients experienced perioperative adverse events.CONCLUSION Type-Ⅰ thyroplasty is an effective surgical method for treatment of vocal cord paralysis.The type-Ⅰ thyroplasty under general anesthesia is safe and effective,which not only significantly improves the symptoms of hoarseness in patients,but also has stable therapeutic effects and can maintain the results for a long time.At the same time,the patient has no pain during the procedure.
