title: Effect of addition of chin strap on PAP compliance, nightly duration of use, and other factors.
abstract: OBJECTIVE
  A chinstrap is potentially useful to reduce unintentional air leak by preventing mouth opening during PAP treatment. This study examines whether the addition of a chinstrap to PAP therapy has any effect on adherence, nightly duration of use, air leak, and residual AHI.
  
  
  METHODS
  This was a retrospective study performed at an AASM-accredited VAMC sleep center. Clinical sleep data of veterans (n = 124) prescribed PAP therapy for sleep apnea was evaluated, and the effect of chinstrap use vs non-use on the above parameters was assessed.
  
  
  RESULTS
  Chinstrap users had significantly greater PAP adherence, longer nightly duration of PAP use, lower residual AHI and lower leak compared to chinstrap non-users at first follow up visit.
  
  
  CONCLUSIONS
  The addition of a chin strap to PAP therapy is a simple and inexpensive method of increasing PAP adherence.
