Materials and Methods In order to do so, children (4 to14 years old) who presented with nasal obstruction or oral breathing complaints were submitted to cavum radiographic examination. One hundred and twenty records were evaluated according to quantitative radiographic parameters, and data were correlated with a gold-standard videonasopharyngoscopic study, in relation to the percentage of choanal obstruction. Subsequently, a regression analysis was performed in order to create an original model so the percentage of the choanal obstruction could be predicted. Results The quantitative parameters demonstrated moderate, if not weak correlation with the real percentage of choanal obstruction. The regression model (110.119*A\/N) demonstrated a satisfactory ability to \u201cpredict\u201d the actual percentage of choanal obstruction. Conclusion Since current adenoid quantitative radiographic parameters present limitations, the model presented by the present study might be considered as an alternative assessment method in cases where videonasopharyngoscopic evaluation is unavailable.<\/jats:p>","DOI":"10.1590\/s0100-39842014000200008","type":"journal-article","created":{"date-parts":[[2014,5,8]],"date-time":"2014-05-08T17:56:04Z","timestamp":1399571764000},"page":"79-83","source":"Crossref","is-referenced-by-count":13,"title":["Radiographic adenoid evaluation: proposal of an objective parameter"],"prefix":"10.1590","volume":"47","author":[{"given":"Murilo Fernando Neuppmann","family":"Feres","sequence":"first","affiliation":[{"name":"Universidade S\u00e3o Francisco, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juliana Sato","family":"Hermann","sequence":"additional","affiliation":[{"name":"Escola Paulista de Medicina \u2013 Universidade Federal de S\u00e3o Paulo (EPM-Unifesp), Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana Carolina","family":"Sallum","sequence":"additional","affiliation":[{"name":", Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shirley Shizue Nagata","family":"Pignatari","sequence":"additional","affiliation":[{"name":"Escola Paulista de Medicina \u2013 Universidade Federal de S\u00e3o Paulo (EPM-Unifesp), Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"548","DOI":"10.1177\/019459988209000505","article-title":"Radiographic evaluation of the symptom-producing adenoid","volume":"90","author":"Crepeau J","year":"1982","journal-title":"Otolaryngol Head Neck Surg"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"569","DOI":"10.1017\/S0022215100102269","article-title":"The adenoidal-nasopharyngeal ratio (AN ratio).
