The aim of this study is to analyze demographic characteristics and clinico-pathological factors of benign SGNs treated in large tertiary institutions and to determine possible correlations between selected variables. &lt;br&gt;&lt;b&gt;Material and method:&lt;\/b&gt; Analysis of 585 patients recorded in SGR and operated on for SGNs in the Department of Otolaryngology and Laryngological Surgery, University of Medical Sciences, Pozna\u0144, Poland, over a 5-year period. Patient age, sex, occupation, place of residence, tumor location, size, histology, recurrence, facial nerve function after surgery, wound healing, surgery procedure, availability of pre-operative imaging examinations, fine-needle aspiration cytology (FNAC) results were analyzed.  &lt;br&gt;&lt;b&gt;Results:&lt;\/b&gt; 338 females and 247 males with a mean age of 53 years were operated on. In total, 96.2% of tumors originated from the parotid and 3.8% from the submandibular gland. The most frequent primary tumor diameter was 2\u20134 cm (59.5%) followed by &lt;2 cm (29.2%) and &gt;4 cm (8.4%). Tumors of over 4 cm were frequently removed by partial superficial parotidectomy, while those under 2 cm \u2013 by extracapsullar dissection (ECD). Pleomorphic adenomas (PA) were predominant (58.8%), followed by Warthin\u2019s tumor (WT) \u2013 37.1%. Patients with WT were on average 13.3 years older than patients with PA.  &lt;br&gt;&lt;b&gt;Discussion:&lt;\/b&gt; This research can be helpful to better understand the clinico-pathological features of SGNs. Long-termin hospital-based analysis is important for subsequent metaanalyses and comparisons with other centers. The reasons why not all patients\u2019 data are reported to the national SGR should be further precisely analyzed.\n\n<\/jats:p>","DOI":"10.5604\/01.3001.0014.1261","type":"journal-article","created":{"date-parts":[[2021,9,22]],"date-time":"2021-09-22T12:32:12Z","timestamp":1632313932000},"page":"1-6","source":"Crossref","is-referenced-by-count":5,"title":["Review and characteristics of 585 salivary\ngland neoplasms from a tertiary hospital\nregistered in the Polish National Major\nSalivary Gland Benign Tumors Registry over\na period of 5 years: a prospective study"],"prefix":"10.5604","volume":"74","author":[{"given":"Krzysztof","family":"Piwowarczyk","sequence":"first","affiliation":[{"name":"Department of Otolaryngology and Laryngological Oncology, Poznan University of Medical Sciences, Poznan, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ewelina","family":"Bartkowiak","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology and Laryngological Oncology, Poznan University of Medical Sciences, Poznan, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanna","family":"Klimza","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology and Laryngological Oncology, Poznan University of Medical Sciences, Poznan, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gra\u017cyna","family":"Greczka","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology and Laryngological Oncology, Poznan University of Medical Sciences, Poznan, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ma\u0142gorzata","family":"Wierzbicka","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology and Laryngological Oncology, Poznan University of Medical Sciences, Poznan, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3689","reference":[{"key":"203237r1","doi-asserted-by":"crossref","unstructured":"Periasamy S., Manoharan A., Garg H., Kumar S.P.: Pleomorphic Adenoma ofthe Cheek: A Case Report.
