BACKGROUND AND IMPORTANCE: Superior laryngeal nerve (SLN) injury after high cervical dissection can result in changes in vocal pitch due to cricothyroid denervation and dysphagia with aspiration risk because of decreased sensation of the supraglottic larynx.
CLINICAL PRESENTATION: We describe a 69-year-old singer with cervical spondylotic myelopathy who underwent elective C3/4 and C4/5 anterior cervical diskectomy and fusion. Postoperatively, the patient reported changes in his voice, most noticeable with higher registers. A number of studies confirmed severe right superior laryngeal neuropathy. A cadaveric description included to highlight anatomic relationships critical in minimizing risk of SLN injury during an anterior cervical diskectomy and fusion approach.
CONCLUSION: The SLN is a critical structure vulnerable to iatrogenic injury during high cervical dissections for anterior approaches to the spine. Therefore, it is critical for spine surgeons to have a firm understanding of SLN anatomy for these approaches.
