A reliable procedure is needed to solve the problem of difficult airway in patients with bilateral vocal cord paralysis without adversely affecting patient “voice quality.”
To compare the results of laser-assisted posterior cordotomy with diathermy-assisted posterior cordotomy for bilateral vocal cord paralysis in regard to dyspnea severity, voice quality, and aspiration.
Prospective randomized clinical trial at a university medical center.
Zagazig University Hospitals, Zagazig, Egypt.
Twenty patients randomly categorized into 2 groups; group A was treated with laser-assisted posterior cordotomy and group B was treated with diathermy-assisted posterior cordotomy.
Laser-assisted posterior cordotomy for group A and diathermy-assisted posterior cordotomy for group B.
Main Outcome and Measure
Dyspnea severity, voice quality, and aspiration.
A significant difference (P < .05) was found between group A and group B at all postoperative comparisons in dyspnea, whereas no significant difference (P ≥ .05) was detected at all postoperative comparisons in voice quality.
Conclusions and Relevance
Laser-assisted posterior cordotomy can be considered as a reliable and superior procedure compared with diathermy-assisted posterior cordotomy in the treatment of bilateral vocal cord abductor paralysis.
