Importance:
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."
Objectives:
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.
Design:
Prospective randomized clinical trial at a university medical center.
Setting:
Zagazig University Hospitals, Zagazig, Egypt.
Participants:
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.
Intervention:
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.
Results:
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.
Trial Registration:
clinicaltrials.gov Identifier: ISRCTN08093874.
