OBJECTIVE: To evaluate the performance of two glossoptosis airway obstruction classifications in predicting symptom severity and laryngeal exposure difficulty in Robin Sequence (RS) patients.
SETTING: Public tertiary hospital otolaryngology section (Hospital de Clínicas de Porto Alegre - HCPA).
PATIENTS: All RS patients diagnosed at HCPA from October 2012 to February 2015 were enrolled, a total of 58 individuals. They were classified in isolated RS, RS-Plus and syndromic RS.
INTERVENTION: Patients were submitted to sleep endoscopy and a score was attributed according to Yellon and de Sousa by a blinded researcher. Symptom severity evaluation was performed as defined by Cole classification.
MAIN OUTCOME MEASURE: Association between endoscopic findings and clinical symptoms severity and laryngeal exposure difficulty.
RESULTS: Twenty four patients were identified as isolated RS (41.4%), 19 patients presented as RS-Plus (32.7%) and 15 patients had well defined diagnosed syndromes (25.9%). Concomitant airway anomalies were found in 18 patients (31%). Specifically 17.4% in isolated RS, 55.6% in RS- Plus and 28.6% in the syndromic group had such anomalies (P = 0,03). Probability of presenting severe clinical symptoms as graded by Cole was higher in grade 3 Yellon classification (68.4%, P = 0.012) and in moderate and severe de Sousa classification (61.5% and 62.5%, respectively, P = 0.015) than in milder grades of obstruction. This findings were considered significant even after controlling for patient age. Laryngeal exposure difficulty was correlated with de Sousa and Yellon (Rho = 0,41 and Rho = 0,43, respectively; P < 0,05).
CONCLUSION: Patients with higher degrees of obstruction in sleep endoscopy had a higher probability of presenting a more severe clinical manifestation and a more difficult laryngeal exposure. Since the number of patients included in this study was small for subgroup analyses, it is not clear if this association is restricted to a specific group of RS.
