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 کاملSchwannoma of the ansa cervicalis
Schwannomas are rare neoplasms that originate from Schwann cells. We present a case report of schwannoma of the ansa cervicalis in a patient where preoperative imaging suggested thyroid pathology. A 25-year-old man presented to the otolaryngology department with a one-year history of an asymptomatic, anterior triangle neck swelling. Imaging and FNA suggested a cystic lesion of the thyroid. Howe...
متن کاملAnatomical study of the human ansa cervicalis nerve and its variations
With the expanding use of the ansa cervicalis nerve for laryngeal reinnervation procedures. So the aim of this work was to study the anatomical variations of ansa cervicalis in its roots, course and branching pattern. Twenty five Egyptian necks (50 sides) were dissected. The results showed that the ansa cervicalis (AC) consisted of two roots: superior and inferior roots. These two roots joined ...
متن کاملVariations in the anatomy of ansa cervicalis.
With the emerging utilisation of ansa cervicalis in nerve reconstructive surgery, it is important for surgeons to be conversant with the anatomy of these nerves. This descriptive cross sectional study aimed at describing the morphology and topographic anatomy of ansa cervicalis. We examined 38 adult human formalin-fixed cadavers. The superior root was present in 38 (100%) cases and 37 (97%) cas...
