Article: Preoperative Laryngeal Nerve Screening for Revision Anterior Cervical Spine Procedures

Objectives: Anterior cervical spine procedures carry an inherent risk of recurrent laryngeal nerve (RLN) injury. Patients with persistent RLN paresis may be asymptomatic because of compensation from the opposite side. If such patients undergo an opposite-side anterior approach for revision surgery, they are at risk for a second RLN injury, creating the potential for bilateral vocal fold paresis and possible need for tracheotomy. A program of routine screening for laryngeal paresis was implemented for these patients. This retrospective study reviews the results of this screening process.

Methods: Patients referred for preoperative laryngeal nerve screening were identified. Their charts were ...
