(A) 102 patients were organized in three clinical groups according to predominant symptoms and disclosing gender. Group 1 contains children suffering from sole nasal obstruction, whereas in the other two groups children also show concomitant infections of the upper airways (group 2) or of the middle ear leading to effusion, hearing impairment and sometimes even impairment in speech development (group 3). For each group, the children's medical history is specified by the clinical symptoms they had presented with in the past. The size of each group in respect to the entire collective is indicated as percentage. (B) All patients were grouped according to age at time of surgery and disclosing gender. Children between the age of 1 and 11 years were included in the study. Comparisons were made between children of 1, 2, and 3 years and older. The size of each group in respect to the entire collective is indicated as percentage. All 102 patients could be analyzed.
