Aim: To evaluate the succes rate of surgical treatment and residual OSAS in a cohort of children
Methods: We performed an observational, longitudinal, ambispectives study in children referred to the Sleep Unit from 2000 to 2010. In all children included, we performed a clinical history, physical and otorhinolaryngology examination and Nocturnal Polysomnography (NPSG) or Nocturnal Polygraphy (NRP). Obstructive apnea/Hypopnea index (OAHI)≥3 on NPSG and respiratory disturbances index (RDI)≥4.6 on NRP were taken as diagnosis of OSAS.
Results: 1139 children were estudied, 672 boys and 467 girls. The average age was 4.85±3.07 years and the average Body Mass Index (BMI) percentile was 52.84±32.39. For the diagnosis, we used NPSG in (50.1%) and NRP in (49.9%) of children included.Snoring and respiratory pauses were reported in 85.9% and 56.9%; Hyperactivity, sleepiness and irritability were reported in 25.5%, 21.8% and 9.2%. 738 (64.8%) of children were diagnosed of OSAS, with an RDI of 9.5±12.6. There were no differences in sex between the OSAS and nonOSAS groups, but there were statistically significant differences in age, weight, neck circunference and BMI.Surgical treatment was performed in 559(75.7%) of OSAS. The success rate was 73.9%; 95% CI:69.01%-78.84% with a statiscally significant improvement in all of clinical and respiratory variables. The prevalence of residual OSAS was 26.1%. In the binary logistic regression model, age BMI, high hard palate and adenotonsillar hypertrophy emerged as a significant risk factors for OSAS.
Conclusions: The persistence of disease (26.1%), in spite of treatment, it makes neccessary to follow-up and perform sleep control studies.
