Abstract
Parathyroid glands always remain at risk of damage during the thyroid surgery as they lie in close proximity
to the thyroid gland. Parathyroid glands are small endocrine glands that produce parathyroid hormone. The
major function of parathyroid hormone is to maintain the level of calcium and phosphate within a narrow
range in the body. Aim of the present study was to locate and identify the parathyroid glands during thyroid
surgery and to observe their relationship with the surgical landmarks. The present study was a prospective
study conducted in the department of otorhinolaryngology and HNS in SMGSH, GMC, Jammu for a time
period of 1 year from Nov.2015 to Oct. 2016. 40 patients undergoing thyroid surgery were included in the
study. Meticulous technique was employed during dissection and parathyroid glands were identified in the
surgical field. Location of the each parathyroid gland was determined in relation to a nearby surgical
landmark. The study included 12 right (R) and 8 left (L) hemithyroidectomies, 10 sub- total thyroidectomies
and 1 total thyroidectomy. An average of 1.2 parathyroid glands were identified in hemithyroidectomies
and 2.4 was the average number of parathyroid glands identified in subtotal and total thyroidectomies.
Location of parathyroid glands was observed in relation to cricothyroid (CT) joint, recurrent laryngeal
nerve (RLN), inferior thyroid artery (ITA) and tubercle of Zukerkandl for superior parathyroid glands, and
in relation to RLN, RLN & ITA junction, tubercle of Zukerdandl & lower pole for inferior parathyroid
glands. In this study RLN was the most frequent landmark for identification of superior parathyroid gland
while the inferior parathyroid glands were frequently seen related to the lower pole of the thyroid gland.
