Arytenoid Dislocation as a Cause of Prolonged Hoarseness after Cervical Discectomy and Fusion

چکیده
Study Design Case series of two arytenoid dislocations after anterior cervical discectomy. Objective To recognize arytenoid dislocation as a possible cause of prolonged hoarseness in patients after anterior cervical discectomies. Summary of Background Data Prolonged hoarseness is a common postoperative complication after anterior cervical spine surgery. The etiology of prolonged postoperative hoarseness is usually related to a paresis of the recurrent laryngeal nerve. However, other causes of postoperative hoarseness may be overlooked in this clinical scenario. Other possible etiologies include pharyngeal and laryngeal trauma, hematoma and edema, injury of the superior laryngeal nerve, as well as arytenoid cartilage dislocation. Arytenoid dislocation is often misdiagnosed as vocal fold paresis due to recurrent or laryngeal nerve injury. Methods We report two cases of arytenoid dislocation and review the literature on this pathology. Results Two patients treated with anterior cervical discectomy and fusion experienced prolonged postoperative hoarseness. Arytenoid dislocation was confirmed by flexible fiber-optic laryngoscopy in both cases. The dislocations experienced spontaneous reduction at 6 weeks and 3 months postsurgery. Conclusions Arytenoid dislocation must be considered in the differential diagnosis of prolonged postoperative hoarseness and evaluated for using direct laryngoscopy, computed tomography, or a laryngeal electromyography. Upon diagnosis, treatment must be considered immediately. Slight dislocations can reduce spontaneously without surgical intervention; however, operative intervention may be required at times.

Background: After cervical discectomy, autogenetic bone is packed into the cage to increase the rate of union between adjacent vertebral bodies, but donor site–related complications can still occur. In this study we evaluate the use of hydroxyapatite granules as a substitute for autograft for interbody fusion. Methods: From November 2008 to November 2011, 236 patients participated in ...

Among others, hoarseness is reported as the most common laryngeal morbidity after general anesthesia, with widely varying incidence from 16% to 55% [3]. However, it is generally resolved within a few days, unless accompanied by serious complications, such as ary...

Arytenoid cartilage dislocation is a rare complication after tracheal intubation, occurring in less than 0.1% of cases [1, 2]. Here we present a case of arytenoid cartilage dislocation following esophagogastroduodenoscopy (EGD). A man in his sixties underwent EGD as a follow-up examination after endoscopic treatment for early gastric cancer. The examination was carried out with a standard endos...

After 12 hours, the patient developed hoarseness, throat pain, and swelling. A computed tomography (CT) scan, barium swallow, and laryngeal electromyography (LEMG) studies showed normal findings. Strobovideolaryngoscopy showed a higher le...
