RESUMO
OBJECTIVE@#To explore the application of polysomnography (PSG) and lateral cephalometric radiographs (LCR) in the diagnosis and treatment of sleep-disordered breathing (SDB) in children.@*METHOD@#To select 157 cases of children suffering from SDB, 115 cases with primary snoring (PS) and 42 cases with obstructive sleep apnea hypopnea syndrome (OSAHS). After bilateral tonsillectomy and adenoidectomy, preoperative and postoperative LCR and PSG of measure were observed for statistical analysis.@*RESULT@#Compared the group PS and group OSAHS; the thickness of adenoids was significantly different(P<0. 01). The preoperative oblique diameter of nasopharyngeal airway was significantly different (P<0. 05). There were significant differences on the preoperative and postoperative nasopharyngeal airway oblique diameter and oropharyngeal airway anteroposterior diameter in group PS and group OSAHS (all, P<0. 01). There were significant differences on the preoperative and postoperative AHI and LSaO2 in the group OSAHS (both, P<0. 01). The total effective rate of group PS was 97. 4% (112/115), and the total effective rate of group OSAHS was 97. 6% (41/42).@*CONCLUSION@#PSG and LCR have a very important role in the diagnosis and treatment of SDB in children. Bilateral tonsillectomy and adenoidectomy are the primary means of treatment in children with SDB.
