Vagus nerve palsy caused by herpes virus infection is rare. Here, the author presents a 65-year-old woman with acute onset of right side otalgia and sore throat, followed by delayed vocal fold paralysis on the same side. Vesicles were also found on the posterior wall of ear canal but the tympanic membrane was not involved. Laryngoscopy revealed multiple ulcerative lesions on the pharyngeal and laryngeal mucosa exclusively on the right side. One month later, she noticed dyshonia which turned out right vocal fold paralysis. Skull base to upper chest CT did not reveal local lesion. Three months after finishing the acyclovir, her symptoms were almost gone and vocal fold movement has almost completely improved. Vagus nerve involvement of herpes infection should be considered as a differential diagnosis for patients with herpes zoster oticus with sore throat.

We present a case report to remind surgeons of this unusual complication that can occur in any surgery, even posterior cervical spine surgery under general anesthesia and discuss its causes, treatment methods, and the follow-up results in the literature. The peripheral Tapia's syndrome is a rare complication of anesthetic airway management. Main symptoms are hoarseness of voice and difficulty of tongue movement. Tapia's syndrome after endotracheal general anesthesia is believed to be due to pressure neuropathy of the vagus nerve and the hypoglossal nerve caused by the endotracheal tube. To our knowledge, no report has been published or given an explanation for Tapia's syndrome after posterior cervical spine surgery. Two patients who underwent posterior cervical surgery complained hoarseness and tongue palsy postoperatively. There is no direct anatomical relation between the operation, the vagus nerves and the hypoglossal nerves, and there is no record of displacement or malposition of the endotracheal tube. After several months, all symptoms are resolved. To avoid this problem in posterior cervical spine surgery, we suggest paying special attention to the position of the endotracheal tube to avoid excessive neck flexion before and during the positioning of the patient.

Background and Objectives : Temporary or permanent vocal paralysis can be occurred after head and neck surgery such as thyroid cancer, esophageal resection, and chest operation including lung parenchymal resection, due to a vagus or recurrent laryngeal nerve injury. The authors aimed to determine the clinical efficacy of using Calcium-Hydroxyapatite (CaHA) for permanent unilateral vocal cord palsy patients. Materials and Method : Between July 2008 to July 2010, among patients with chief complain of hoarseness and aspiration, only who were diagnosed as unilateral vocal cord palsy under laryngoscopy, were selected. The patients included 3 females and 13 males age range between 29 to 79 and average age was 60 years old. Results : The hoarseness range were $8.94{\pm}0.77$, $4.63{\pm}1.02$, $4.31{\pm}1.30$ statistically showing significant postoperative improve at preoperative, 1 week and 3 months. Also aspiration were $7.44{\pm}2.48$, $3.63{\pm}1.82$, $3.19{\pm}1.91$ statistically improved during the same period. The result of voice analysis showed that the frequency range shows decrease at 1 week and 3 months after the injection compared to that of the preoperative result in both male and female group (Male: $161.63{\pm}32.78$ Hz, $139.13{\pm}30.63$ Hz, $146.67{\pm}34.20$ Hz ; Female: $244.62{\pm}26.62$ Hz, $244.91{\pm}42.03$ Hz, $237.50{\pm}38.95$ Hz). The Maximal phonation time were $2.75{\pm}1.06$ (sec), $8.88{\pm}3.46$ (sec), $8.44{\pm}3.71$ (sec) statistically showing significant postoperative improve at preoperative, 1 week and 3 months. Conclusion : Injection laryngoplasty with CaHA in unilateral vocal cord paralysis is very safe and efficient procedure to improve a voice disorder, a swallowing difficulty, and a quality of life for those patients with a sacrificed RLN, a cancer invasion of the nerve, and a prolonged vocal cord paralysis which is more than six to twelve months.
