Abstract:
Objective To explore the difference of lingual arterial CT angiography images (CTA) between obstructive sleep apnea hypopnea syndrome (OSAHS)patients and normal subjects, and to investigate the safety of partial glossectomy guided by lingual arteria CT angiography. Methods Seventy-four patients with OSAHS and 10 control adults were included in the study. The lingual upper airway and lingual arterial CT angiography were obtained. The area and the dimensions of lingual upper airway, and the length and thickness of lingua, length of lingual arteria, depth and bilateral lingual arteria spacing were studied. The CT measuring data of OSAHS patients and normal adults were compared. The muhinomial logistic regression analysis was used to investigate the main factors which affects the lingual arterial measuring results. Guided by the lingual arterial CT angiography and measuring results, glossectomy was performed in 23 OSAHS patients with lingua hypertrophy. Results The area and dimensions of lingual airway of OSAHS patients were less than those of control adults, and the length and thickness of lingua of OSAHS were more than those of control adults (t test, P<0.05 or P<0.01). There were no difference in length of lingual arteria and bilateral lingual arteria specing between OSAHS patients and control adults. The 3 measured points'depth ((-)x±s) of lingual arteria of OSAHS patients were (29.1±5.5) mm, (26.9± 5.1)mm and (25.6±5.2) mm, respectively, and those of control adult were (23.0±3.8) mm, (22.6± 2.7) mm and (21.5±2.6) mm, the depth of lingual arteria of OSAHS was more than that of control adults (t test, P<0.05 or P<0.01). The main factors affects lingual arterial depth were body mass index (BMI), Iingual length and lingual thickness, unstandardized regression coefficient were 0.255, 0.11 and 0.03,repectively (analysis of variance, F=6.216, P<0.05). No damage of lingual arteria and nerve in 23 patients who had expanded glossectomy. Conclusions The study showed statistical difference significance of lingual arterial CTA measurements between OSAHS patients and control adults. Guided with lingual arteria CTA data, the expanded glossectomy in OSAHS patients has proved good safety and high cure rate.
