RESUMO

Objectives: To investigate the short- and long-term effect of pharyngeal flap surgery (PFS) on the internal nasal dimensions of patients with velopharyngeal insufficiency (VPI) and to correlate the findings with the onset of respiratory complaints (RC) after surgery. Model/Patients: Prospective study in 58 patients with repaired cleft palate and VPI, evaluated, on average, 2 days before (PRE), 5 (POST1) and 14 months (POST2) after surgery, divided into 2 groups: one consisting of patients with RC (WRC) at POST2 and the other without RC (WtRC). Differences between groups and stages were considered to be significant at the 5% level. Site: Laboratory of Physiology, Hospital for Rehabilitation of Craniofacial Anomalies, Brazil. Interventions: Superiorly based PFS. Variables: RC (oral respiration, snoring and respiratory difficulty during sleep), and minimal nasal (NA) and nasopharyngeal (NPA) cross-sectional area assessed by rhinomanometry. Results: RC were observed in 55% of patients at POST1 and 36% at POST2. Posterior rhinomanometry showed: 1) a significant reduction of mean NA at POST1 and POST2 compared to PRE, in both groups. No significant changes were observed by anterior rhinomanometry; 2) significantly lower mean NA in the WC group compared to the WtC group at POST2; 3) more pronounced reduction in NA values in the WC group. NPA measurements confirmed these findings. Conclusions: In the short term, PFS led to a significant reduction in the nasopharyngeal dimensions in a significant proportion of patients, part of whom started to present RC; in the long term, this effect was attenuated but did not fully disappear.
