Cervical spinal cord compression after thyroidectomy under general anesthesia

Acute cervical spinal cord injury after head and neck surgery: A CARE case report

OBJECTIVE

To describe and analyze a case of acute spinal cord injury after head and neck surgery.

DESCRIPTION

One hour after left lobo-isthmectomy under laryngeal neuromonitoring for a 3-cm EU-TIRADS 4 - Bethesda 4 thyroid nodule in a 48-year-old euthyroid male without any known comorbidity, left hemiparesis occurred. Cervical spine MRI showed an anteromedial herniated C6-7 disk with medullary compression. The disk was resected, compression was released and C6-7 fusion was performed via an anterior cervical approach on postoperative day 1. Postoperative course was unremarkable, with complete recovery of motion within 2 days. One month later, neurological clinical examination was normal and interview revealed left cervicalgia with onset a few days prior to lobo-isthmectomy. One year later, at the time of writing, the patient was doing fine.

CONCLUSION

Otorhinolaryngologists and head and neck surgeons must be aware of the risk of acute cervical spinal injury after cervical mobilization in head and neck surgery, and should take all measures to avoid this exceptional but dramatic complication.

Working Space Creation in Transoral Thyroidectomy: Pearls and Pitfalls

Simple Summary

Transoral thyroidectomy accesses the thyroid gland through three incisions in the oral vestibule. The cosmetic outcome was excellent since no scar was observed on the body surface. However, it is challenging to create a working space using this new approach. Unconventional but severe complications can also occur. Our review summarizes the tips regarding working space creation in transoral thyroidectomy and tricks for preventing complications.

Abstract

Transoral thyroidectomy is a novel technique that uses three small incisions hidden in the oral vestibule to remove the thyroid gland. It provides excellent cosmetic results and outcomes comparable to the open approach. One of the main obstacles for this technique is the creation of a working space from the lip and chin to the neck. The anatomy of the perioral region and the top-down surgical view are both unfamiliar to general surgeons. As a result, inadequate manipulation might easily occur and would lead to several unconventional complications, such as mental nerve injury, carbon dioxide embolism, and skin perforation, which are rarely observed in open surgery. Herein, we summarize the basic concepts, techniques, and rationales behind working space creation in transoral thyroidectomy to assist surgeons in obtaining an adequate surgical field while eliminating preventable complications.
