1Acute suppurative otitis media. 2Acute sinusitis. 3Obstructive sleep apnea syndrome. 4Due to visual evaluation during intraoperative tympanocentesis and suction. 5A: normal curve; B: flat curve due to middle ear fluid. C: deviated curve due to negative middle ear pressure. All tympanometric measurements were performed the day before adenoidectomy. 6Recurring acute otitis media group. 7Otitis media with effusion group. 8Obstructive sleep apnea syndrome group.
