Adenoidal tissue is developed as part of Waldeyer’s lymphatic ring during the first years of the child’s life. It reaches maximum volume at 6 years old and begins to disappear at the age of 8 to 10 years old. During adulthood it is reduced to a small pharyngeal cavity. When hyperthophic adenoids take place, both respiratory and general growth alterations may be observed in the child. To determine patterns of adenoids involution, adenoidal tissue and nasopharyngeal areas were measured using teleradiography, according to Handelman and Osborne’s method.
Bone age was obtained through Bjork and Helm’s bone maturity analysis from hand radiographies which were compared to the Bone Maturity Atlas of Canals et a1.
A sample of 5 groups was selected. Each group comprised 20 subjects aged between 10 and 14 years old. Results were explored using linear regression analysis validated with variance analysis.
