Laryngeal reinnervation for unilateral vocal fold paralysis using ansa cervicalis nerve to recurrent laryngeal nerve anastomosis
In laryngeal paralysis, the stiffness of the denervated vocal fold is decreased. This leads to deviant vibratory patterns involving 2 asymmetric vocal folds and results in abnormal vocal quality. Follow-up studies of medialization thyroplasty patients have noted that decrement in vocal quality after medialization is often because of continuing vocal fold atrophy. Vocal cord atrophy from denerva...
متن کاملBridging gaps between the recurrent laryngeal nerve and ansa cervicalis using autologous nerve grafts.
OBJECTIVES/HYPOTHESIS We investigated the clinical efficacy of free nerve grafts in bridging gaps between the recurrent laryngeal nerve (RLN) and ansa cervicalis in patients with unilateral RLN injury. STUDY DESIGN We retrospectively reviewed the charts of 14 patients who underwent relevant free nerve grafting and assessed the clinical outcomes of this procedure. METHODS Between January 200...
متن کاملA variant case of ansa cervicalis
Ansa cervicalis (ansa cervicalis profunda, ansa nervi hypoglossi) is one of the nerve connections in the human body. Two roots make up the ansa cervicalis –radix superior and radix inferior. Its sources include the ventral rami of the cervical spinal nerves; ansa innervates all infrahyoid muscles except for the thyrohyoid muscle [1,2]. In the past few years, there has been a development in the ...
متن کاملContralateral ansa cervicalis-to-recurrent laryngeal nerve anastomosis for unilateral vocal fold paralysis: a long-term outcome analysis of 56 cases.
OBJECTIVES/HYPOTHESIS To evaluate the long-term efficacy of contralateral ansa cervicalis-to-recurrent laryngeal nerve (RLN) anastomosis for unilateral vocal fold paralysis (UVFP), when the ansa cervicalis on the side of the paralyzed vocal fold was absent or there was any question about its viability. STUDY DESIGN We retrospectively reviewed 56 consecutive cases of delayed laryngeal reinnerv...
متن کاملResults of ansa to recurrent laryngeal nerve reinnervation.
OBJECTIVE We sought to describe the results of ansa cervicalis to recurrent laryngeal nerve (ansa-RLN) reinnervation for unilateral vocal fold paralysis. STUDY DESIGN A chart review was performed on patients undergoing ansa-RLN reinnervation for unilateral vocal cord paralysis at a tertiary care center. Patient perceptions of preoperative and postoperative voice quality was surveyed. Acoustic...
