目的探讨CT测量乳晕入路腔镜甲状腺手术操作空间的临床意义。方法回顾性分析488例乳晕入路腔镜下甲状腺手术患者的CT资料,收集颈部操作空间长度(L)、高度(H)、腔镜器械与气管食管沟角度(α)数据,根据以上数据计算腔镜器械操作盲区(Lb)及有效区范围(Le)。结果女性L值大于男性,H值小于男性,α值大于男性,差异均有统计学意义(均P<0.05)。男性Lb值大于女性,Le值小于女性,差异均有统计学意义(均P<0.05)。结论国人女性比男性更适合乳晕入路腔镜甲状腺手术,多数男性不适合乳晕入路进行中央区清扫。CT测量乳晕入路腔镜甲状腺手术操作空间的方法,具有很好的临床指导意义。
ObjectiveTo investigate the clinical significance of CT measurement of operating space in endoscopic thyroid surgery via areola approach. MethodsThe CT data of 488 patients undergoing endoscopic thyroid surgery via areola approach were retrospectively analyzed. The data of neck operation space length (L), height (H), angle between endoscopic instrument and tracheoesophageal sulcus (α) were collected. According to the above data, the blind area (Lb) and the effective area (Le) ranges of endoscopic instrument operation were calculated. ResultsCompared with males, females had higher L value and α value, and lower H value, with statistically significant differences (all P<0.05). Compared with females, males had higher Lb value and lower Le value, with statistically significant differences (all P<0.05). ConclusionChinese females are more suitable for endoscopic thyroid surgery via areola approach than males, while most males are not suitable for central dissection via areola approach. CT measurement of operating space in endoscopic thyroid surgery via areola approach has good clinical guiding significance.
