Measuring Diaphragm Thickness in Adolescents with Chest Deformities

Ultrasonographic Measurement of Diaphragmatic Thickness in Adolescents With Pectus Deformity: Is it an Early Predictor of Respiratory Dysfunction?

Observational Gaziosmanpasa Research and Education Hospital · NCT06392984

This study is testing how thick the diaphragm is in teenagers with chest deformities to see if it can help predict breathing problems before they show any symptoms.

What this trial studies

This observational study aims to measure diaphragmatic thickness in adolescents aged 10-18 with pectus deformities, such as pectus excavatum and pectus carinatum. The researchers will utilize ultrasonography to assess diaphragm function and thickness, investigating its potential as an early predictor of respiratory disorders in patients who may not exhibit clinical symptoms. The study will include pulmonary function tests to correlate diaphragm measurements with respiratory health. By focusing on this demographic, the study seeks to enhance understanding of how pectus deformities impact respiratory function.

Who should consider this trial

Good fit: Ideal candidates are adolescents aged 10-18 with increased thoracic kyphosis and the ability to cooperate with spirometry.

Not a fit: Patients with congenital anomalies, neuromuscular diseases, or existing respiratory conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide early indicators of respiratory issues in adolescents with pectus deformities, leading to timely interventions.

How similar studies have performed: While the use of ultrasonography for diaphragm assessment is gaining traction, this specific approach in adolescents with pectus deformities is relatively novel.
