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

Condition(s) studied

Investigational drug(s) / intervention(s)

USG: Masseter Muscle Thickness and Internal Echogenic Bands Assessed by Ultrasonography

Study summary

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.

Eligibility

Primary outcome measure(s)

• Masseter Muscle Thickness and Internal Echogenic Bands Assessed by Ultrasonography — At enrollment (single assessment)
  The masseter muscles of both groups will be evaluated using a LOGIQ S8 R4 ultrasound device with a 9L linear probe. All participants will be examined in the supine position. The probe will be placed: Transversely: Along a line extending from the oral commissure to the ear tragus Longitudinally: Perpendicular to the mandibular body The thickness of the right and left masseter muscles will be measured in millimeters, both at rest and during maximum clenching, from the thickest region of the muscle. Internal echogenic bands will be classified into three types: * Type 1: Clear, thin transverse bands * Type 2: Thickened bands with reduced echogenicity * Type 3: Disappearance or reduction in the number of bands
