Which of the following findings on polysomnography (PSG) specifically indicates the need for post-adenotonsillectomy monitoring in an inpatient setting in children with OSA, as per current paediatric guidelines?

• A AHI 2/hour with no desaturation below 93%
• B Moderate tonsil hypertrophy grade 3+ on examination
• C Bilateral otitis media with effusion on otoscopy
• D Age under 3 years, AHI >10, or oxygen saturation nadir <80% ✓

Explanation

Children at high risk for post-operative respiratory complications after adenotonsillectomy — including those aged under 3 years, severe OSA (AHI >10 events/hour), oxygen saturation nadir <80% on PSG, obesity, craniofacial anomalies, or neuromuscular disease — require inpatient overnight monitoring with pulse oximetry. Tonsil size grade and OME are not risk stratification criteria for post-operative monitoring.
