Abnormalities can be classified as: non-neoplastic, neoplastic benign, and neoplastic malignant.<\/jats:p><jats:p>\n            Objective\u2003Evaluate through CT the prevalence of diseases in maxillary sinuses, using the Radiology Department's database of a hospital in S\u00e3o Paulo city. <\/jats:p><jats:p>\n            Methods\u2003The sample consisted of 762 facial CT scans that we divided into three groups: Group A (12\u201319 years old); Group B (20\u201349 years old); Group C (above 50 years old); and male or female. We considered the following pathological processes: I - Mucoperiosteal Thickening; II - Chronic Sinusitis; III - Chronic Odontogenic Sinusitis; IV - Rhinosinusitis; V - Polypoid Lesions; VI - Bone Lesions; VII - Neoplasms; VIII - Antrolith; IX - Foreign Bodies; X - Oroantral Fistula.<\/jats:p><jats:p>\n            Results\u2003Our study found that 305 exams (40.02%) were normal and 457 exams (59.97%) were abnormal. We found the following disease frequencies: focal mucoperiosteal thickening (21.25%); polypoid lesions (10.76%); chronic sinusitis (7.48%); chronic odontogenic sinusitis (2.29%); neoplasms (2.03%); rhinosinusitis (1.77%); bone lesions, foreign bodies and oroantral fistula in 0.65%; 0.13% and 0.06% respectively. There was no significant difference between male and female, and Groups A, B, or C when relating the frequencies of abnormalities found. There was no significant difference between male and female and the age group for the side of the altered maxillary sinus.<\/jats:p><jats:p>\n            Conclusion\u2003We observed a high prevalence of sinus maxillary diseases. Mucoperiosteal thickening; acute, chronic, and odontogenic sinusitis; polypoid lesions and neoplasms have high prevalence in maxillary sinuses. Thus, facial CT exam was effective for the evaluation of diseases in maxillary sinuses.<\/jats:p>","DOI":"10.1055\/s-0036-1593834","type":"journal-article","created":{"date-parts":[[2016,12,17]],"date-time":"2016-12-17T04:30:42Z","timestamp":1481949042000},"page":"126-133","source":"Crossref","is-referenced-by-count":47,"title":["Evaluation of the Prevalence of Maxillary Sinuses Abnormalities through Spiral Computed Tomography (CT)"],"prefix":"10.1055","volume":"21","author":[{"given":"Jo\u00e3o","family":"Drumond","sequence":"additional","affiliation":[{"name":"Department of Oral Implantology, Universidade de Santo Amaro Ringgold Standard Institution, S\u00e3o Paulo, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bruna","family":"Allegro","sequence":"additional","affiliation":[{"name":"Department of Radiology and Diagnostic Imaging, Hospital Heliopolis Ringgold Standard Institution, S\u00e3o Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Neil","family":"Novo","sequence":"additional","affiliation":[{"name":"Department of Statistics and Health Sciences, Universidade de Santo Amaro Ringgold Standard Institution, S\u00e3o Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00e9rgio","family":"de Miranda","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology Head and Neck Surgery, Universidade Federal de Sao Paulo Ringgold Standard Institution, S\u00e3o Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wilson","family":"Sendyk","sequence":"additional","affiliation":[{"name":"Department of Oral Implantology, Universidade de Santo Amaro Ringgold Standard Institution, S\u00e3o Paulo, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2016,12,16]]},"container-title":["International Archives of Otorhinolaryngology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0036-1593834.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,6]],"date-time":"2019-05-06T18:39:16Z","timestamp":1557167956000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0036-1593834"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,12,16]]},"references-count":0,"journal-issue":{"issue":"02","published-online":{"date-parts":[[2017,3,31]]},"published-print":{"date-parts":[[2017,4]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0036-1593834","relation":{},"ISSN":["1809-9777","1809-4864"],"issn-type":[{"value":"1809-9777","type":"print"},{"value":"1809-4864","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016,12,16]]}}}
