The anatomical relationship between recurrent laryngeal nerve and inferior thyroid artery in thyroidectomy patients.

Abstract

Objective: To identify the anatomical relationship of recurrent laryngeal nerve with inferior thyroid artery. Study Design: Prospective Clinical study. Setting: Department of Surgery, Kishwar Fazal Teaching Hospital. Period: July 2019 to February 2023. Methods: Total 64 patients underwent subtotal thyroidectomies for proven benign goiters were enrolled. Results: Out of these 64 patients, 8 were male and 56 were female, male to female ratio 1:7 with median age 34 years. In 64 patients, 128 dissections were performed and in all patients (RLN) and its relation with Inferior Thyroid Artery (ITA) was identified. On right side of neck in 63 (98.43%) patients out of 64 (100%) patients RLN found deeper to ITA and in one (1.56%) patient it was found superficial to ITA. On left side of neck in 61 (95.31%) patients out of 64(100%) patients it was deeper to ITA and in 3 (4.68%) patients the nerve was superficial to ITA. Identification of RLN was difficult in 16 (12.5%) dissections and the reason was adhesions and huge multinodular goiter. Conclusion: During thyroid surgery, the connection between RLN and ITA is significant to surgeons. When it comes to RLN security, visible anatomical identification is still the gold standard.
