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 ...

The involvement of the inferior or recurrent laryngeal nerve (RLN) in mobility derangement of the vocal folds occurs more frequently due to thyroid malignancy invasion. Although uncommon, the same derangement, which is caused by benign thyroid entities, is also described and reverts to normality after a thyroidectomy in up to 89% of cases. In these cases, the pathogenesis of the vocal cord mobi...

Introduction: Ortner Syndrome (OS) is a disorder that presents with hoarseness due to compression of the Left Recurrent Laryngeal Nerve (LRLN) vascular origin, such as cardiac pathology.

In the present study the Authors tried and assess the advantages of the standard sutureless thyroidectomy performed by the Ligasure Vessel Sealing System, thanks to the use of the dedicated Precise handle. The Authors compared the efficacy of haemostasis and the economical impact of the device, in terms of drug administration and costs. The Authors comparatively analyzed 120 total extracapsular...

OBJECTIVES Vocal cord paresis or paralysis due to iatrogenic injury of the recurrent laryngeal nerve (RLNI) is one of the main problems in thyroid surgery. Although many procedures have been introduced to prevent the nerve injury, still the incidence of recurrent laryngeal nerve palsy varies between 1.5-14%. The aim of the present study is to assess the risk factors of recurrent laryngeal nerve...

The lesions of the laryngeal nerves, despite low incidence, are the most severe long term complications after thyroidectomy. Visualization after careful dissection of the recurrent laryngeal nerve (RLN) is now the golden standard among thyroid surgeons. We assessed traditional landmarks for the identification of RLN and anatomic high risk situation. The study also presented our initial experien...

Background: Injuries to the recurrent inferior laryngeal nerve (RLN) remain one of major post-operative complications after thyroid surgery. In studies, temporary RLN damage during thyroidectomy is %2-11, and rate permanent %0.6-1.6. Complementary thyroidectomies have a higher complication compared first surgical procedure. last two decades, intraoperative neural monitoring has become powerful ...

Recurrent laryngeal nerve palsy is a common post-operative complication of many head and neck surgeries. Theoretically, the best treatment to restore partial function to a damaged recurrent laryngeal nerve would be reinnervation of the posterior cricoarytenoid muscle via anastomosis of the recurrent laryngeal and phrenic nerves. The pig is an excellent model of human laryngeal anatomy and physi...
