The "TIP algorithm" for the accurate diagnosis of pediatric otitis media.

Objectives: The authors studied the correlation between the grading TIP which evaluates three otoendoscopic characteristics of the tympanic membrane (TM) (transparency, integrity and position) with the gold standard represented by the impedenzometry.

Methods And Materials: Cross-sectional studies with independent and blind comparison with the gold standard diagnostic. The setting was primary care and ambulatory.
