“…The TZ is the posterior extension of the thyroid lateral lobes or a protuberance from the posterolateral border of the thyroid lobe [1-8]. It is significantly more common in the right than in the left lobe [5, 7, 8, 11-13]. It is usually observed in the middle third of the thyroid lateral lobe (80–85%) and it can also be found in the lower part or in the upper third of the lobe [1].…”

“…In addition, TZs differ in shape or size depending on whether they are fresh or fixed [7]. The TZ is present in 60–83% of the patients undergoing thyroidectomy [1, 2, 5, 8, 10-13]. In this study, however, only 2.9% of the thyroidectomy cases were included.…”

“…Thyroid tubercle of Zuckerkandl (TZ) is a protuberance or nodule arising from the posterolateral thyroid tissue [1-8]. It was first described in 1902 by the Viennese anatomist Emil Zuckerkandl as “Processus posterior glandulae thyroideae” [9].…”

The TZ is present in 60–83% of the patients undergoing thyroidectomy [1, 2, 5, 8, 10-13] and is mostly located in the mid-third of the thyroid lobe [1]. It is an important landmark for the identification of the recurrent laryngeal nerve during thyroid surgery because most recurrent laryngeal nerves pass beneath the TZ [1, 2, 5, 14].…”

Thyroid tubercle of Zuckerkandl (TZ) is a nodule arising from the posterolateral thyroid, considered to be a remnant of the ultimobranchial body (UB). Considering that C cells and solid cell nests also arise from the UB, we hypothesized that these would be present in the TZ. We examined the presence of C cells and solid cell nests in the TZ using the histological analyses of 21 patients with grade 2 or 3 TZs following Pelizzo’s grading system. Out of 21 TZs, 19 (90.5%) were located in the right lobe of the thyroid. Microscopically, solid cell nests were found within the TZ in 1 case (4.8%), and within the main thyroid tissues in 3 cases (14.3%). Calcitonin-positive C cells were scattered within the TZ in 1 case (4.8%), and within the main thyroid tissue in 15 cases (71.4%). The distribution of C cells within the main thyroid tissue was denser than that within the TZ. The above-mentioned results indicated the lack of C cells and solid cell nests in the TZ. Although the TZ may have an embryological origin different from that of ordinary thyroid tissue, it is unlikely that the remnants of the UB are involved in the formation of the TZ.

RESUMO Objetivo: avaliar se a projeção lateral da glândula tireoide, chamada tubérculo de Zuckerkandl (TZ), pode auxiliar o cirurgião na identificação do nervo laríngeo inferior durante a tireoidectomia convencional aberta. Métodos: estudo prospectivo de 51 pacientes submetidos à tireoidectomia, com um total de 100 lobos tireoidianos ressecados, e observação da presença ou não do TZ em dimensões suficientes para ser identificado sem magnificação de imagem, suas dimensões de base e altura, sua localização na glândula e sua relação anatômica com o nervo laríngeo inferior. Resultados: o TZ estava presente em 68 dos 100 lobos de tireoide analisados (68%). A dimensão média da base foi 6,7mm no lado direito e 7,1mm no lado esquerdo, e a altura média foi 5,7mm no lado direito e 6,1mm no lado esquerdo. Na maioria dos lobos estudados, o tubérculo tinha altura mínima de 5mm (55,9%) sem diferença significativa entre o lobo direito e esquerdo da glândula tireoide. Durante a cirurgia, 100% dos TZ identificados estavam anteriores ao nervo laríngeo inferior, imediatamente abaixo da entrada do nervo na laringe. Conclusão: o TZ é bastante frequente e em dimensões suficientes para ser usado como referência anatômica na localização intraoperatória do nervo laríngeo inferior, próximo à sua entrada na laringe, junto com as demais referências anatômicas.
