Objective To investigate the clinical effect of microflap suture under self-retaining laryngoscope on benign vocal cord diseases.Methods A total of 115 patients with benign vocal cord diseases who underwent surgical treatment in the Binhai People's Hospital Affiliated to Kangda College of Nanjing Medical University and Nanjing Tongren Hospital Affiliated to School of Medicine of Southeast University were enrolled in this retrospective study.According to the surgical treatment methods,the patients were divided into observation group(58 patients were treated with microflap suture under self-retaining laryngoscope)and control group(57 patients received conventional surgery).The treatment effect,Voice Handicap Index-10(VHI-10)score,the scales of overall grade(G),roughness(R),breathiness(B),asthenian(A)and strain(S),and voice related parameters were compared between the two groups.Results The overall treatment effect of the observation group was significantly better than that of the control group(P<0.05).There were no significant differences in the VHI-10 score functional score,physiological score,emotional score,VHI-10 score,GRBAS score,longest phonation time,recording fundamental frequency,fundamental frequency perturbation,amplitude perturbation,or voice harmonic ratio before treatment between the two groups(P>0.05).After treatment,the VHI-10 score functional score,emotional score,total score),GRBAS score,the value of fundamental frequency perturbation and voice harmonic ratio in the observation group were significantly lower than those in the control group(P<0.05);the longest phonation time in the observation group was significantly longer than that in the control group(P<0.05).Conclusion Microflap suture under self-retaining laryngoscope is an effective treatment for benign vocal cord diseases,and the voice recovery is better after surgery.
