ABSTRACT
BACKGROUND:
The purpose of this work was to compare methods of detecting nonrecurrent laryngeal nerves (NRLNs).METHODS:
Specificity and sensitivity were compared in three NRLN detectionmethods:
CT, electromyography (EMG), and A-B point comparison.RESULTS:
A total of 73 intraoperative pictures and 36 CT details of NRLNs are presented. Incidence of NRLN was 0.39%. Type I NRLN accounted for 50.7%, type IIA 45.2%, type IIB 4.1%. The NRLN median latency was 2.13 ms vs 3.00 ms median in an RLN control group (P < .001). When the threshold was set to 2.5 ms, EMG latency detection had 96.7% sensitivity and 91.6% specificity for detecting NRLN, and the A-B point comparison algrithm had 97.3% sensitivity and 92.5% specificity. Combining EMG latency detection with A-B point comparison achieved 100% sensitivity and specificity for detecting NRLN.CONCLUSION:
This is the largest series of NRLN presented in the literature. Latency shorter than 2.50 ms combined with the A-B point comparison method is the ideal algorithm procedure for early NRLN identification.Palavras-chave
