**4. Conclusions**

Obstructive sleep apnea syndrome is a complex condition with many sequelae. Patient signs and symptoms must be combined with sleep studies to diagnose this condition. Nonsurgical treatments, such as weight reduction, oral application and CPAP, are the first treatments of choice in adults. Surgery such as adenotonsillectomy is the treatment of choice for clearly enlarged adenoids and tonsils in children. DISE is a very useful tool for directing surgical intervention to the most obstructed level. Many surgical interventions have been studied and used to address obstructions with good results.
