Abstract
Objective:To discuss the correlation of benign vocal cord lesions with occult vocal cord sulcus and the treatment of benign vocal cord lesions with occult vocal cord sulcus, through the analysis of surgical data, preoperative voice evaluation data and postoperative follow-up data of patients.Method:The data from 377 patients of benign vocal cord lesions with concealed vocal cord sulcus admitted to Beijing Tongren Hospital from 2005 to 2016 were reviewed. The follow-up time was more than half a year after surgery.Result:About 2.9% of the benign lesions of the vocal cords were associated with occult vocal cords sulcus,of which 61.27% were bilateral vocal cords sulcus,22.55% was right vocal cords sulcus,and 16.18% was left vocal cord sulcus.Of the patients with bilateral vocal fold sulcus,64.5% had benign vocal cord lesions and 35.5% had unilateral vocal cord benign lesions.Of the patients with unilateral vocal fold,73.97% were associated with ipsilateral vocal cord benign lesions, and 26.03% were associated with contralateral vocal cord lesions.In the 531 sides of the vocal cords sulcus,183 sides of vocal fold sulcus typeⅠwere not treated. The 332 sides of vocal fold sulcus type Ⅱ were treated with removed lesions of the vocal cords and microdissection of vocal cord adhesion.The 16 sides of vocal fold sulcus type Ⅲ were treated with removed lesions of the vocal cords,local tamponaded of autogenous abdominal fascia and microsutured to close the wound. There were 9 cases with 11 sides of vocal fold sulcus combined with the mucous bridge.The satisfactory rate of sound improvement was 80.37% in half a year after the operation.Postoperative fundamental frequency,jitter,shimmer and maximum phonation time were significantly improved compared with preoperative.Conclusion:The occurrence of benign vocal cord lesions may be related to occult vocal fold sulcus.Simultaneous treatment of benign vocal cord lesions with occult vocal cord sulcus can achieve satisfactory voice improvement.Therefore, we should pay attention to the treatment of vocal fold sulcus in the diagnosis and treatment of benign vocal cord diseases.
