上颌窦手术常采用局麻方法,即沿切口部浸润麻醉加眶下孔和上颌结节阻滞麻醉。很少应用蝶腭神经节和圆孔阻滞麻醉。手术区感觉神经由上颌神经分支和蝶腭神经节后纤维分布,有的认为鼻和鼻窦感觉神经还按受颈交感神经千上部的纤维。上颌窦手术麻醉应阻断上述的神经分支,通常使用的上颌结节麻醉法,不能保证完全阻断后上牙槽神经,因此切除上颌窦后上壁粘膜时病人往往感觉疼痛,有时发
Maxillary sinus surgery often use local anesthesia method, that is along the incision anesthesia with infraorbital foramen and maxillary nodules block anesthesia. Few applications of sphenopalatine ganglion and round hole block anesthesia. The sensory nerve in the surgical field is distributed by the maxillary nerve branches and the posterior fissure fibers of the sphenopalatine ganglion. Some people think that the sensory nerves of the nasal and sinus nerves also press the fibers of the upper cervical sympathetic trunk. Maxillary sinus surgery anesthesia should block the nerve branches, the commonly used method of maxillary nodules, can not be completely blocked after the upper alveolar nerve, so the removal of maxillary sinus mucosa after the upper wall when the patient often feel pain, and sometimes hair
