title: Morphological study of recurrent laryngeal nerve in relation to thyroid gland.
abstract: The study was done to see the relationship of recurrent laryngeal nerves with corresponding inferior thyroid artery with the aim to increase the knowledge regarding variational anatomy in our population. Sixty samples were collected as block dissection of thyroid gland along with the surrounding structures containing the supplying vessels and adjacent nerves from 48 male and 12 female cadavers of different age groups and fixed in 10% formol-saline solution. Fine dissections were carried out to study the toporgaphic relationship of recurrent laryngeal nerves with corresponding inferior thyroid artery. The findings were compared between different age groups and also with the findings of western researchers. In this study, in majority of the cases the recurrent laryngeal nerves were found in their usual location that is posterior to the terminal branches of inferior thyroid artery on the left side and anterior to that artery on the right side. It was important to note that, on both sides recurrent laryngeal nerves were also frequently found to pass in between the terminal branches of inferior thyroid artery.
