Abstract

Thyroidectomy is a commonly performed surgery for various thyroid diseases. The common complications associated with a thyroid surgery are recurrent laryngeal nerve palsy (unilateral or bilateral), hypoparathyroidism due to injury to parathyroid glands during surgery. We employed the technique of identifying recurrent laryngeal nerve at its entry point using cricothyroid muscle as land mark and noted the frequency of recurrent laryngeal nerve palsy and hypoparathyroidism in this technique.Objective: To predict the frequency of occurrence of recurrent laryngeal nerve palsy and permanent hypo-parathyroidism during thyroidectomy by identifying the recurrent laryngeal nerve at its entry point using cricothyroid muscle as landmark and retrograde tracking of it.Material and methods: We conducted a retrospective study at two tertiary care centres in India. In this study, we took all the patients of thyroidectomise where recurrent laryngeal nerve was identified at its entry point using cricothyroid muscle as landmark and traced in a retrograde manner. A total of 36 patients were included in the study. We predicted the frequency of recurrent laryngeal nerve palsy and hypoparathyroidism by using our method to identify recurrent laryngeal nerve.Results and discussion: In present study there was no permanent laryngeal nerve palsy but the frequency of permanent hypoparathyroidism was 11.6 %.
