Abstract Objective: To investigate upper airway structure of snoring children through measuring upper airway and surrounding structures of the primary snoring (PS) and obstructive sleep apnea-hypopnea syndrome (OSAHS) children on the lateral X ray film. Methods: The children who came to this hospital because of snoring from October 2008 to December 2010 were be selected. According to the results of polysommography, the children were divided into PS group (53 cases), mild OSAHS group (51 cases), moderate and severe OSAHS group (57 cases). 50 cases unsnoring children were be selected as control group. The four groups were examined with lateral X ray film, and the craniofacial hard tissues, soft tissues, upper airway and space structure were measured. Results: Bone sex structures measured: the hyoid-mandible plane distance (AH-MP), hyoid-frankfort horizontal plane distance (AH-FH), hyoid-precervical vertebra plane distance (AH-CVP)of the three snoring groups obviously increased as compared with the normal group (P<0.05). There was no statistical differences among three snoring groups. Soft tissues measured: the adenoid area (AA) of snoring groups obviously increased as compared with the normal group (P<0.05). The moderate and severe OSAHS group was the maximum, and there was nostatistical differences between PS group and mild OSAHS group. The adenoid thickness (AT), soft palate length (SPL), soft palate thickness (SPT), and soft palate area (SPA) of snoring groups obviously increased as compared with the normal group (P<0.05). There was no statistical differences among snoring groups. Upper airway measured: the posterior airway interstitial (PAS), nasopharyngeal airway area (NA), and nasopharyngeal airway anteroposterior diameter (PNS- UPW) of snoring groups obviously decreased as compared with the normal group (P<0.05). The moderate and severe OSAHS group were the least, and there was no statistical differences between PS group and mild OSAHS group. The palatopharyngeal airway area (PA) and posterior soft palate- posterior soft palate pharynxwall distance (namely palatopharyngeal airway anteroposterior diameter, SPP-SPPW) of snoring groups obviously decreased as compared with the normal group (P<0.05). There was no statistical differences among snoring groups. Space structures measured: the adenoidal - nasopharyngeal ratio (A/N) and adenoidal area-nasopharyngeal area ratio (AA/NTA) of snoring groups obviously increased as compared with the normal group (P<0.05). The moderate and severe OSAHS group was the maximum, and there was no statistical differences between PS group and mild OSAHS group. The PAS-trachea diameter ratio (PAS/TD)of snoring groups obviously decreased as compared with the normal group (P<0.05). The moderate and severe OSAHS group were the least, and there was no statistical differences between PS group and mild OSAHS group. The result of the correlation analysis showed that the correlations between AT, AA, SPA, A/N, AA/NTA and AHI were all positive and significant (P<0.05). The correlations between NA, PNS-UPW, PA, SPP-SPPW, PAS, PAS/TD and AHI were all negative and significant (P<0.05). Conclusion: Adenoidal hypertrophy obstruct the nasopharyngeal airway, the hypertrophy of tonsils and soft palate make the palatopharyngeal and glossopharyngeal airway more serious. Low order and forward hyoid is one of the reasons lead to OSAHS. Lateral X ray film is used to understand upper airway and surrounding structure, and it has important value in research of upper airway structure in snoring children.
