Evidencia y recomendación. ¿La neuromonitorización intermitente es útil para la reducción de parálisis de nervio laríngeo recurrente en cirugía de tiroides?

Abstract

Introduction and objective: Clinical Question. In a patient with thyroid disease [patient], submitted to thyroidectomy [intervention], the use of neuromonitoring against the single visual identification of recurrent laryngeal nerve (RLN) [comparison], offers advantages? [result]. Material and Methods: Literature review in PubMed, Scopus and Cochrane Library data descriptors and search strategy: (((((((laryngeal) OR larynx)) AND nerve) AND monitoring) AND thyroidectomy)) AND meta-analysis. 10 items in English or Spanish of which 7 were selected for the qualitative study were obtained. Results: Level of evidence. Evidence for the lower incidence of transient unilateral paralysis in patients with neuromonitoring is moderate-high. Evidence on the lower incidence of permanent unilateral paralysis of RLN with NM is low. Evidence on the lower incidence of bilateral paralysis of RLN with neuromonitoring is low. Conclusions: Recommendation. Concerning the reduction of transient paralysis of the RLN the recommendation of the use of neuromonitoring in thyroid surgery is strongly in favor. Regarding permanent paralysis recommendation is weak in favor (no recommendation against). Regarding prevention of bilateral laryngeal paralysis recommendation for weak. The decision to use NM cannot be based on the incidence of RLN paralysis.
