The anterior approach in cervical spine surgery may lead to hoarseness of the throat. Cervical spine surgery usually adopts both anterior and posterior surgical methods. If anterior cervical spine surgery is performed, the supraglottic and recurrent laryngeal nerves may be affected during the surgery, causing the nerves to be stretched or irritated, and hoarseness or choking on water may occur after the surgery. Damage to the superior laryngeal nerve or the recurrent laryngeal nerve is the most common cause of hoarseness after anterior surgery, which is a temporary injury. Drinking warm water and moisturizing the throat can gradually restore the voice after surgery. However, there are a very small number of cases in which the relevant nerves are cut or stitched during the operation, which cannot be recovered. If cervical spine surgery leads to hoarseness of the throat, it is recommended that the patient informs the doctor in time to clarify the cause of the disease and treat or cure it in time to avoid further development of the disease.
