Patients recruited from Akademiska Sjukhuset, Örebro, Västra Götaland, Skåne, Stockholm and Umeå.

Questionnaire with 22 questions of symptoms of OSDB

Level of baseline PSQ of children who are referred to surgery. A level of >33% yes i.e. 8/22 indicates medium to severe OSA and less than five yes indicates a healthy status. Minimum is 0 yes and maximum is 22 where 22 is the most severe disease.

PSQ has a score from 0 to 22 where every yes on the scale is one point. A level of 8 "yes" (>33%) indicates moderate to severe OSDB and less than five indicates no OSDB.

Changes of baseline PSQ with 6 months follow-up, after treatment/surgery

Compare PSQ-levels with OSA-18 levels OSA-18 is accounted as a scale from 18 to 126 points where a higher rate is a more severe disease. Score less than 60 suggests a mild impact on quality of life. Scores between 60 and 80 a moderate impact and a score higher than 80 severe impact.

OSA-18 has a summary of 18 - 126 points where a higher level indicates worse quality of life. A score less than 60 indicates a mild impact on quality of life and score between 60 and 80 indicates moderate impact whereas a score above 80 indicates a high impact.
