Evaluation of the Effect of Adenoid Hypertrophy on the Masseter Muscle in Children: A Comparative Ultrasonographic Study

The goal of this observational study is to evaluate the effect of adenoid hypertrophy on the masseter muscle in children aged 3 to 8 years. The primary objectives are: * To assess whether adenoid hypertrophy affects the thickness or structure of the masseter muscle. * To determine whether there is a measurable difference in masseter muscle characteristics between children with and without adenoid hypertrophy. Researchers will compare children diagnosed with adenoid hypertrophy and scheduled for adenoidectomy to healthy controls without adenoid hypertrophy. Each participant will: * Undergo ultrasonographic examination of the masseter muscle using a 9L linear probe (6-15 MHz), and * Have their occlusal relationship, dental findings, age, sex, and adenoid hypertrophy grade recorded.
