Abstract
The primary objective of the study was to assess the Tubercle of zuckerkandl (TZ) during thyroid surgeries and its relationship with RLN and Superior parathyroid (SP). A prospective study was done in, 30 consecutive cases of total thyroidectomy in whom per operatively TZ was identified. The presence of TZ, its laterality, size, relationship with RLN and parathyroid glands were documented. A grading system outlined by Pelizzo was applied in our current study. In majority of the cases the RLN was found to lie medial to TZ (26/30), followed by lateral position (3/30) and one case it was found to be posterior to TZ (1/30). The superior parathyroid was identified in close relation (< 2 cm) to the TZ in 27/30 cases. The distance between the TZ and SP was assessed. We proposed a classification for location of SP based on the distance between SP and TZ and also attempted to relate each class of SP location with TZ grade. There was strong association of Grade of TZ with the class of SP location (p value = 0.00046). TZ is constant surgical landmark with good reliability to identify the RLN and SP. RLN is found medial to TZ in majority of cases with few exceptions. SP is found to be closely associated with TZ in majority of cases and there is a strong relationship of proximity of SP and TZ with respect to TZ grade. Although this required further studies with larger population.
