Аннотация
PURPOSE: This study aimed to assess the outcomes of posterior cordotomy in cases with bilateral abductor vocal fold immobility (BAVFI), either by radiofrequency or CO2 laser.
METHODS: This prospective comparative randomized study included 80 patients with BAVFI of different etiologies. They were divided randomly into two groups. Group A included 44 patients for whom radiofrequency was used for posterior cordotomy, while the other group (group B) included 36 patients managed by CO2 laser-assisted posterior cordotomy.
RESULTS: The postoperative respiratory chink improved significantly in both groups, with a significant improvement in the dyspnea, especially in group B. The postoperative voice handicapped VHI-10 scores showed significant deterioration in both groups.
CONCLUSIONS: CO2 laser and radiofrequency-assisted posterior cordotomy were effective and safe for managing cases with BAVFI. Moreover, the CO2 laser has the upper hand regarding breathing and exercise tolerance outcomes, significantly impacting the quality of life.
