A retrospective study by Spektor et al indicated that the risk of postoperative bleeding in children undergoing tonsillectomy is increased when the surgery is performed on a child with recurrent tonsillitis (4.5 times increased risk), on a child with attention deficit hyperactivity disorder (8.7 times increased risk), or on an older child (twice the bleeding risk in children aged 11 years or above). [25]

Similarly, a study by Kshirsagar et al indicated that in children undergoing outpatient tonsillectomy with or without adenoidectomy, the risk of immediate postoperative bleeding is increased by older age (age between 9 and 18 years) and obesity, with the latter making the likelihood of hemorrhage about 2.3 times greater.
