Objectives To compare respiratory function, swallowing and voice quality of bilateral abductor vocal fold paralysis ( BAVFP ) patients undergoing laser and diathermy‐assisted posterior cordotomy. Design Prospective study. Setting Tertiary academic hospital. Participants Thirty patients were included in the study (groups 1 and 2, 15 patients each). Mean age was 53 ± 14.27 years with a range of 31‐78 years (12 [40%] males, 18 [60%] females). Main outcome measures Sufficient airway, complications, FEV 1, FEV 1/ FVC , peak expiratory flow rate ( PEF ), voice quality VAS , fundamental frequency, jitter, shimmer, NHR , amplitude perturbation quotient ( APQ ) and pitch perturbation quotient ( PPQ ) scores. Results A sufficient laryngeal airway was achieved in all patients. Six patients (20%) developed postoperative granulation tissue (2 in group 1 and 4 in group 2). There was a statistically significant improvement in FEV 1, FEV 1/ FVC and PEF measurements at the postoperative sixth month compared to preoperative measurements in both of the groups ( P < .05). Preoperative median voice quality VAS scores in groups 1 and 2 were 8 ( IQR = 1) and 8 ( IQR = 3), respectively. Postoperative sixth‐month voice quality VAS scores in groups 1 and 2 were 6 ( IQR = 1) and 6 ( IQR = 0), respectively. Postoperative VAS scores were significantly lower in both groups ( P < .05). The postoperative changes in fundamental frequency, NHR , jitter, shimmer, APQ and PPQ were not statistically significant in both of the groups ( P > .05). Conclusions Laser and diathermy‐assisted posterior cordotomy are both minimally invasive, effective techniques with a long‐term sufficient laryngeal airway. Despite lower quality of voice VAS scores, objective acoustic outcomes were not significantly lower in both of the groups.
