Introduction: The adenoid hypertrophy can cause several health impacts: changes in craniofacial development, sleep disorders, impaired weight gain and even nocturnal enuresis. The diagnosis of this disease has undergone several changes over time and the gold standard is nasal videoendoscopy, however with difficult access in the public health system. Objective: To measure the diagnostic accuracy of lateral cranial radiography (LCR) in the diagnosis of pharyngeal tonsillar hypertrophy compared to nasal videoendoscopy in pediatric patients. Material and methods: We evaluated 35 patients aged between 5 and 14 years old seen at the Pediatric Otorhinolaryngology outpatient clinic evaluated for the possibility of adenoid hyperplasia, being submitted to nasal videoendoscopy and classified second Brodsky scale for hyperplasia being also performed cavum radiography whose classification for adenoid size was considered the nasopharyngeal adenoid ratio (NAR). Results: The lowest nasopharyngeal adenoid NAR was 0.38 and the highest was 0.95. In turn, Brodsky's percentage classification showed maximum and minimum values of 99% and 25% respectively. The sample showed a Pearson correlation of 0.72 between the NAR and Brodsky's percentile classification variables, thus presenting a strong positive relationship. Conclusions: Nasal videoendoscopy is a medium complexity exam, which requires specific equipment and the presence of a specialist to perform. The LRC on the other hand is a non-invasive and financially more accessible propaedeutic technique in primary care.  This study showed that LRC is a viable and safe alternative to nasal videoendoscopy, since it shows good correlation and accuracy.
