腭骨分垂直板和水平板两部分。水平板构成硬腭的后份,在中线形成腭中缝,垂直板上缘有眶突和蝶突,两突之间的切迹称蝶腭切迹,蝶腭切迹与蝶骨底部形成蝶腭孔,蝶腭动脉、鼻腭神经、鼻后上神经经蝶腭孔入鼻腔;垂直板前缘与上颌窦内壁后份相接,构成上颌窦内壁的后1/3;后缘与翼突内侧板相接,构成翼腭窝的前上缘。腭骨在鼻内上颌窦开窗术中为蝶腭动脉的重要定位标志。简要复习了该区的解剖并报道了向腭部延伸的经中鼻道上颌窦开窗术及其疗效。手术在局麻下进行,静脉注射止痛剂及镇静剂,经翼腭管注入2%利
Palatal bone points vertical plate and horizontal plate in two parts. The horizontal plate forms the posterior part of the hard palate, forming the palate suture in the midline, the orbital process and the butterfly process on the upper edge of the vertical plate, the notch between the two processes called the sphenopalatine notch, the sphenopalatine notch and the sphenoid palatal hole , The sphenopalatine artery, nasal palate nerves and nasal posterior superior nerve transsphenoidal palate into the nasal cavity; the leading edge of the vertical plate and posterior part of the maxillary sinus wall connected to form the posterior 1/3 of the maxillary sinus; the posterior border and the medial plate of the wing, Connected to form the upper edge of the pterygopalatine fossa. Palatal bone in the intranasal maxillary sinus fenestration of the sphenopalatine artery important positioning markers. The anatomy of the area was briefly reviewed and the trans-nasal maxillary sinus fenestration extending to the palate was reported and its efficacy.
