摘要: 目的

通过对替牙列期和恒牙列期患者硬腭前份麻醉效果的观察,研究硬腭前份的神经支配以及与个体发育和年龄的关系,为临床前腭部局部麻醉方式的选择以及颌面部神经发育研究提供参考。

方法

182例替牙列期患者随机分为鼻腭组和腭大组,分别采用鼻腭神经阻滞麻醉和腭大神经阻滞麻醉。219例恒牙列期患者分为青少年组(13~18岁)和成人组(19岁以上),均行腭大神经阻滞麻醉。以Von Frey测痛仪检测麻醉前后硬腭前份黏膜痛觉变化来评价麻醉效果。

结果

替牙列期患者中,除切牙乳头区外,双侧腭大神经麻醉效果优于鼻腭神经麻醉(P<0.05)。青少年组与成人组患者腭大神经阻滞麻醉效果差异无统计学意义(P>0.05),而替牙列期患者腭大神经麻醉效果显著优于恒牙列期患者(13岁以上者)(P<0.05)。

结论

替牙列期患者硬腭前份可能主要由腭大神经支配,但随着上颌骨的发育和牙列替换,鼻腭神经逐渐发挥作用,并在硬腭前份感觉神经支配中起主要作用,这提示支配硬腭前部的感觉神经随着上颌骨的发育存在二次发育的可能。

Abstract: Objective

The present study aimed to explore the innervation of the anterior hard palatine and its relationship with individual development stage. Specifically, the effects of anesthesia on patients of different ages were observed, and neurodevelopment in the maxillofacial region was invesitgated. References that are helpful in selecting local anesthesia were provided.

Methods

A total of 182 patients with mixed dentition were randomly divided into the nasopalatine nerve block and greater palatine nerve block groups. Then, 219 patients with permanent dentition were divided into an adolescent group (13-18 years old) and adult group (over 19 years old), all of whom underwent bilateral greater palatine nerve block. Palatal mucosal pain sensation was tested pre- and post-anesthesia with Von Frey hairs.

Results

Among the children with mixed dentition, bilateral greater palatine nerve block tended to result in better anesthetic effects than nasopalatine nerve block (P<0.05), except in the incisive papilla. No difference in anesthetic effect was observed between adolescents and adults (P>0.05). The bilateral greater palatine nerve block was more effective in inducing an anesthestic effect in the anterior hard palatine in mixed dentition than in permanent dentition (over 13 years old; P<0.05).

Conclusion

The sensation of the anterior hard palatine seems mainly dominated by the greater palatine nerve until mixed dentition and gradually shifted to the nasopalatine nerve in conjunction with maxillary development and tooth replacement. Hence, the innervation of the anterior hard palatine induce a secondary development during the development of the maxilla.
