RESUMO

Aim: This study aimed to describe, compare and analyze the characteristics of tympanometric findings with 226 Hz, 678 Hz and 1000 Hz tone probes. Model: Cross-sectional Location: Department of Speech Pathology and Audiology, Hospital for Rehabilitation of Craniofacial Anomalies, USP, Bauru. Participants: Sixty eight subjects with cleft lip and palate, non-operated, both genders, aged between three and twelve months. Interventions: anamneses, otoscopy and multifrequency tympanometry. Results: Given the occlusion effect, of 365 tympanograms, 136 were obtained for the 226 Hz probe, 94 for 678Hz and 135 for 1000 Hz probe. Single-peak curve was the most prevalent at the three probe frequencies: 79.41% at 226 Hz, 40.42% at 678 Hz and 37,04% at 1000 Hz. PD curve was found at 678 Hz and 1000 Hz occurring 5.32% and 1.48% respectively. ASS and INV curves were visualized 7, 45% at 678 Hz; 8,89% at 1000 Hz for ASS and 21,28% at 678 Hz, 24,44% at 1000 Hz for a INV curve. PL curve occurred in all frequencies at 20.59%, 25.53%, and 28.15% for the 226 Hz, 678 Hz and 1000 Hz probes, respectively. Conclusion: Different kinds of curves were found including: Double peak(DP), asymmetric (AS), inverted (INV) and plan (PL). Results indicated most prevalence of single-peak curves for 1000 Hz probe. The 226 Hz probe showed single-peak and plan curves as well. The 678 Hz probe showed all kinds of curves being the single-peak the most prevalent.
