[INCIDENCE AND SURGICAL IMPORTANCE OF PYRAMIDAL LOBE AND TUBERCLE OF THE THYROID GLAND: A PROSPECTIVE STUDY].

The pyramidal lobe and tubercles are common anatomic variations of the thyroid gland, and their frequency is highly represented. While pyramidal lobe requires additional seriousness in identifying and its removal, especially in patients with hyperthyroidism and thyroid cancer, the presence of tubercles is desirable. Tubercle is covered by recurrent laryngeal nerve and directs the surgeon in his search and besides this, serves to facilitate detection of the upper parathyroid glands.
