The following meta\u2010analysis aims to provide a detailed analysis of the anatomical variations of the PL using the available data in the literature. Major online medical databases such as PubMed, Scopus, Embase, Web of Science, Cochrane Library, and Google Scholar were searched in order to find all studies considering the prevalence and anatomy of the PL of the thyroid gland. Finally, a total of 24 studies that met the required criteria and contained complete and relevant data were included in the present meta\u2010analysis. The pooled prevalence of the PL was found to be 42.82% (95% CI: 35.90%\u201349.89%). An analysis showed that the mean length was 23.09\u2009mm (SE: 0.56). The mean width was found to be 10.59\u2009mm (SE: 0.77). The pooled prevalence of the PL originating from the left lobe (LL) was established at 40.10% (95% CI: 28.83%\u201351.92%). In conclusion, we believe that this is the most accurate and up\u2010to\u2010date study regarding the complete surgical anatomy of the PL. The PL was prevalent in 42.82% of the cases, being slightly more prevalent in males (40.35%) than females (37.43%). The mean length and width of the PL were 23.09\u2009mm and 10.59\u2009mm, respectively. Our results should be taken into consideration when performing procedures on the thyroid gland, such as thyroidectomies. The presence of the PL can affect the completeness of this procedure and lead to postoperative complications.<\/jats:p>","DOI":"10.1002\/ca.24062","type":"journal-article","created":{"date-parts":[[2023,5,28]],"date-time":"2023-05-28T11:29:20Z","timestamp":1685273360000},"page":"937-945","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["The prevalence and anatomy of the pyramidal lobe of the thyroid gland: A meta\u2010analysis with implications for thyroid surgery"],"prefix":"10.1002","volume":"36","author":[{"given":"Patryk","family":"Ostrowski","sequence":"first","affiliation":[{"name":"Department of Anatomy Jagiellonian University Medical College Krak\u00f3w Poland"},{"name":"Youthoria, Youth Research Organization Krak\u00f3w Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2080-165X","authenticated-orcid":false,"given":"Micha\u0142","family":"Bonczar","sequence":"additional","affiliation":[{"name":"Department of Anatomy Jagiellonian University Medical College Krak\u00f3w Poland"},{"name":"Youthoria, Youth Research Organization Krak\u00f3w Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joe","family":"Iwanaga","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery Tulane University School of Medicine New Orleans USA"},{"name":"Department of Oral and Maxillofacial Anatomy, Graduate School of Medical and Dental Sciences Tokyo Medical and Dental University Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mateusz","family":"Michalczak","sequence":"additional","affiliation":[{"name":"Department of Anatomy Jagiellonian University Medical College Krak\u00f3w Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martyna","family":"Dziedzic","sequence":"additional","affiliation":[{"name":"Department of Anatomy Jagiellonian University Medical College Krak\u00f3w Poland"},{"name":"Youthoria, Youth Research Organization Krak\u00f3w Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alicia","family":"del Carmen Yika","sequence":"additional","affiliation":[{"name":"Department of Anatomy Jagiellonian University Medical College Krak\u00f3w Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Gil","sequence":"additional","affiliation":[{"name":"Department of Anatomy Jagiellonian University Medical College Krak\u00f3w Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mateusz","family":"Sporek","sequence":"additional","affiliation":[{"name":"Department of Anatomy Jagiellonian University Medical College Krak\u00f3w Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"El\u017cbieta","family":"Szczepanek","sequence":"additional","affiliation":[{"name":"Department of Anatomy Jagiellonian University Medical College Krak\u00f3w Poland"},{"name":"Department of Otorhinolaryngology and Head and Neck Surgery Medical University of Warsaw Warsaw Poland"},{"name":"Doctoral School in Medical Sciences and Health Sciences Jagiellonian University Medical College Cracow Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazimierz","family":"Niemczyk","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology and Head and Neck Surgery Medical University of Warsaw Warsaw Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jerzy","family":"Walocha","sequence":"additional","affiliation":[{"name":"Department of Anatomy Jagiellonian University Medical College Krak\u00f3w Poland"},{"name":"Youthoria, Youth Research Organization Krak\u00f3w Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mateusz","family":"Koziej","sequence":"additional","affiliation":[{"name":"Department of Anatomy Jagiellonian University Medical College Krak\u00f3w Poland"},{"name":"Youthoria, Youth Research Organization Krak\u00f3w Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,5,28]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.15557\/JoU.2018.0042"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.amsu.2021.102823"},{"key":"e_1_2_9_4_1","doi-asserted-by":"crossref","first-page":"1450","DOI":"10.4103\/njcp.njcp_326_17","article-title":"Incidence of pyramidal thyroid lobe in the university college hospital Ibadan","volume":"21","author":"Ayandipo O.
