既往临床在拔除上颌第三磨牙时,均采用传统麻醉方法,即上牙槽后神经与腭大孔阻滞麻醉。此项麻醉方法,技术要求高、难度大。我科自1990年起采用腭大孔与牙周浸润麻醉拔除上颌第三磨牙,此项麻醉方法具有显效迅速、麻醉范围局限、损伤小、拔牙时出血少、缩短手术时间、安全系数大等优点,且麻醉方法简便易行,效果满意,值得临床推广应用。现报告如下。 Previous clinical removal of the maxillary third molars, the traditional method of anesthesia, namely the upper alveolar nerve and palate large hole anesthesia. This method of anesthesia, high technical requirements, difficult. Since 1990, our department has used maxillary palate and periodontal infiltration anesthesia to remove maxillary third molars. This anesthesia method has the advantages of rapid onset, limited anesthesia range, less damage, less bleeding during tooth extraction, shorter operation time and greater safety factor , And anesthesia method is simple and effective, satisfactory results, it is worth clinical application. The report is as follows.
