鼻内解剖结构变异与慢性头痛的关系

Relationship between nasal anatomical abnormality and chronic headache

目的：研究鼻解剖结构变异与慢性头痛的关系。方法：对40例鼻解剖结构变异患者分为伴头痛组与不伴头痛组，内镜及鼻窦CT评估其鼻解剖结构变异类型、接触黏膜对血管收缩剂的敏感性。结果：两组鼻结构变异类型及骨间隙值差异无统计学意义，头痛组接触部位黏膜对血管收缩剂敏感性差。结论：骨结构变异基础上接触部位黏膜挤压张力增加及鼻窦自然口阻塞是鼻结构变异性头痛的主要原因。

Objective： To study the relationship between nasal anatomical abnormality and chronic headache. Methods： 40 cases were divided into a headache group and a non-headache group. Evaluation was performed according to the criteria of having contact points between the septum and the lateral nasal wall, and the CT value of spatium interosseum was determined, as demonstrated by CT scans of the sinuses and endoscopic examinations. Results： There was no significant difference between two groups in nasal anatomical abnormality and the CT value of spatium interosseum （P〉0. 01）. The headache group were poor sensitive to vasoconstrictor. Conclusion： The main cause of intranasal contact point headache is pressure from mucosal contact between the septum and lateral nasal wall mucosa and maxillary sinus orifice occlusion.
