Materials and Methods: Patient data and irradiation parameters were collected in examinations of the paranasal sinuses in children from 0 to 15 years of age at two children's hospitals in the city of Recife, PE, Brazil. We estimated the Ka,e using the X-ray tube outputs and selected parameters. To estimate the air kerma values in the regions of the eyes and thyroid, we used thermoluminescent dosimeters.  Results: The Ka,e values ranged from 0.065 to 1.446 mGy in cavum radiographs, from 0.104 to 7.298 mGy in Caldwell views, and from 0.113 to 7.824 mGy in Waters views. Air kerma values in the region of the eyes ranged from 0.001 to 0.968 mGy in cavum radiographs and from 0.011 to 0.422 mGy in Caldwell and Waters views . In the thyroid region, air kerma values ranged from 0.005 to 0.932 mGy in cavum radiographs and from 0.002 to 0.972 mGy in Caldwell and Waters views.  Conclusion: The radiation levels used at the institutions under study were higher than those recommended in international protocols. We recommend that interventions be initiated in order to reduce patient exposure to radiation and therefore the risks associated with radiological examination of the paranasal sinuses.<\/jats:p>","DOI":"10.1590\/0100-3984.2015.0081","type":"journal-article","created":{"date-parts":[[2016,5,4]],"date-time":"2016-05-04T23:33:05Z","timestamp":1462404785000},"page":"79-85","source":"Crossref","is-referenced-by-count":5,"title":["Dosimetric evaluation of X-ray examinations of paranasal sinuses in pediatric patients"],"prefix":"10.1590","volume":"49","author":[{"given":"Beatriz de Lucena Villa-Chan","family":"Cantalupo","sequence":"first","affiliation":[{"name":"Universidade Federal de Pernambuco,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aline Carvalho da Silva","family":"Xavier","sequence":"additional","affiliation":[{"name":"Pontificia Universidad Cat\u00f3lica de Chile,  Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Clemanzy Mariano Leandro da","family":"Silva","sequence":"additional","affiliation":[{"name":"Faculdade Integrada de Pernambuco,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcos Ely Almeida","family":"Andrade","sequence":"additional","affiliation":[{"name":"Universidade Federal de Pernambuco,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vin\u00edcius Saito Monteiro de","family":"Barros","sequence":"additional","affiliation":[{"name":"Universidade Federal de Pernambuco,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Helen Jamil","family":"Khoury","sequence":"additional","affiliation":[{"name":"Universidade Federal de Pernambuco,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"issue":"2-4","key":"ref1","first-page":"1","article-title":"The 2007 Recommendations of the International Commission on Radiological Protection","volume":"37","year":"2007","journal-title":"Ann ICRP"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"1827","DOI":"10.1016\/j.ijporl.2012.09.010","article-title":"Relationship between adenoid size and severity of obstructive sleep apnea in preschool children","volume":"76","author":"Tagaya M","year":"2012","journal-title":"Int J Pediatr Otorhinolaryngol"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"279","DOI":"10.1016\/j.jped.2013.09.004","article-title":"Radiographic adenoid evaluation - suggestion of referral parameters","volume":"90","author":"Feres MF","year":"2014","journal-title":"J Pediatr (Rio J)"},{"key":"ref4","doi-asserted-by":"crossref","first-page":"571","DOI":"10.1016\/S1808-8694(15)30605-4","article-title":"ENT care of children and adolescents in the Brazilian public healthy system in three different municipalities","volume":"74","author":"T-Ping C","year":"2008","journal-title":"Braz J Otorhinolaryngol"},{"key":"ref5","doi-asserted-by":"crossref","first-page":"392","DOI":"10.1046\/j.1365-2273.2000.00381.x","article-title":"Age-specific size of the normal adenoid pad on magnetic resonance imaging","volume":"25","author":"Vogler RC","year":"2000","journal-title":"Clin Otolaryngol Allied Sci"},{"key":"ref6","doi-asserted-by":"crossref","first-page":"413","DOI":"10.1590\/S0102-35862003000600016","article-title":"Abordagem diagn\u00f3stica da tosse cr\u00f4nica em pacientes n\u00e3o-tabagistas","volume":"29","author":"Jacomelli M","year":"2003","journal-title":"J Bras Pneumol"},{"key":"ref7","series-title":"Tratado de t\u00e9cnica radiol\u00f3gica e base anat\u00f4mica","author":"Bontrager KL","year":"1999","edition":"4\u00aa ed"},{"key":"ref8","doi-asserted-by":"crossref","first-page":"17","DOI":"10.1016\/S1078-8174(97)80021-1","article-title":"Patient dose audit in diagnostic radiography using custom designed software","volume":"3","author":"Davies M","year":"1997","journal-title":"Radiography"},{"key":"ref9","doi-asserted-by":"crossref","first-page":"2237","DOI":"10.1088\/0031-9155\/43\/8\/017","article-title":"Calculation of back-scatter factors for diagnostic radiology using Monte Carlo methods","volume":"43","author":"Petoussi-Henss N","year":"1998","journal-title":"Phys Med Biol"},{"key":"ref10","series-title":"ABNT NBR ISO\/IEC 17025:2005 - Requisitos gerais para a compet\u00eancia de laborat\u00f3rios de ensaio e calibra\u00e7\u00e3o","year":"2005"},{"key":"ref11","series-title":"Diretrizes de prote\u00e7\u00e3o radiol\u00f3gica em radiodiagn\u00f3stico m\u00e9dico e odontol\u00f3gico.
