Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Evaluation of obstrutive parameters and craniofacial growth ina consecutive series of children with Obstructive Sleep Apnea after adenotonsillectomy;There were improvements in some obstructive parameters in adenotonsilectomized Obstructive Sleep Apnea children. ;There were not changes in the maxillary and mandibular pattern growth in adenotonsilectomized Obstructive Sleep Apnea children. | — |
Secondary
| Measure | Time frame |
|---|---|
| Assessment of pulmonary artery systolic pressure (PASP); inspiratory nasal flow (INF); apnea/hipopnea index (AHI); upper airway volume and craniofacial growth ;Pulmonary artery systolic pressure (PASP) exhibited more reduction in the adenotonsilectomized children (16.6%) ;Inspiratory nasal flow (INF) increased in adenotonsilectomized children (40.3%), and non-adenotonsilectomized children (16.8%);The upper airway volume increased in adenotonsilectomized and non-adenotonsilectomized children, but more volumetric gain (45.6%) was found in the nasopharynx of adenotonsilectomized patients.;Apnea/hipopnea index (AHI) did not decrease in six adenotonsilectomized children (55%) and in three non-adenotonsilectomized children (75%);In six T&A children (55%) and two untreated children (50%) the maxilla displaced downward and backward, relative to the cranial base. In nine of the T&A children (85%), and in three untreated children (75%), there was increase of the mandibular length, and condylar growth -Qualitative assessment showed the same pattern of facial changes in T&A and non-T&A patients. | — |
