title: Radiological parameters of the bony nasopharynx and the adenotonsillar size compared with sleep apnea episodes in children.
abstract: The role of enlarged adenoids and tonsils in recurrent respiratory infections and upper airway obstruction has become well-established earlier. In this study we investigated the relationship between the X-ray properties of the nasopharynx and the sleep quality by using a new sleep registration method: The Static Charge Sensitive Bed (SCSB). The estimation of the bony nasopharyngeal dimensions, the measurement of adenotonsillar volume and the sleep recordings were performed as adenoidectomy, tonsillectomy or adenotonsillectomy in hospitalized children. A surprisingly high frequency of sleep apnea episodes was found in sleep recordings of about 8 h. No correlations could be established between the X-ray anatomical estimates and sleep apnea episodes.
