Which of the following is a true statement regarding polysomnography (PSG):
a) PSG is useful in distinguishing between obstructive sleep apnea and central sleep apnea
b) If apnea-hypopnea index is <1, tonsillectomy is contraindicated
c) According to the practice guideline of the American Academy of Otolaryngologists and Head and Neck Surgeons (AAO-HNS), every child with night time snoring should be evaluated with PSG
d) According to the AAO-HNS practice guidelines, overnight home pulse oximetry is a good substitute for PSG
e) children with apnea-hypopnea index of less than 20 are good candidates for outpatient adenotonsillectomy
Answer
Answer a.
Attended, overnight, laboratory-based polysomnography (PSG) remains the gold standard in diagnosing obstructive sleep apnea, but its availability is limited. An obstructive apnea-hypopnea index of 10 or higher signifies severe disease. Adenotonsillectomy has indications other than obstructive sleep apnea.
