Objective: To evaluate the anatomical and voice results of conservative management of patients diagnosed with contralateral reactive lesions (CRL) in our voice unit.
Methods: A retrospective chart review was conducted of all new adult patients with benign vocal fold lesions with or without CRL, treated in the voice unit at Universidad Católica Clinical Hospital between 2015 and 2019. Patients were divided into two groups, without CRL (group A) and with CRL (group B). Analysis of preoperative and 1 month after surgery videostroboscopy, GRBASI, Voice Handicap Index-10 (VHI-10), Voice Related Quality of Life (VRQOL) surveys and management of CRL was conducted.
Results: A total of 62 patients were included, 45 (72.6%) had CRL. When compared, bivariate and multivariate analysis revealed that age was significantly associated as a mild protective factor of presenting a CRL (P < 0.05). No significative differences were found between preoperative group A and B perceptual voice analysis or voice surveys. In terms of CRL management, 30 (66.6%) were injected, conservative management with observation was performed in 12 patients (26.7%) and, three (6.7%) were surgically resected. After 1 month follow-up, 32 (71.1%) had complete CRL resolution, eight (17.8%) had CRL persistence and, five (11.1%) had CRL recurrence. Postoperative vocal outcomes, GRBASI, VHI-10 and VRQOL showed significative improvement as compared with preoperative data for each group. No differences were seen between group A and B in terms of postoperative vocal outcomes.
Conclusion: CRL are prevalent, and their management is controversial. On our study 72.6% of BFVL presented with CRL and 93.3% of them were conservatively managed. Improvement in perceptual voice analysis and quality of life surveys were similar in both groups.
