摘　　要：目的探讨上颌前方牵引联合上颌唇挡治疗上颌发育不足的临床效果。方法选取2021年3月至2022年5月赣州市妇幼保健院收治的60例上颌发育不足患儿作为研究对象,采用随机数字表法分为研究组和参照组,每组30例。参照组采用单纯上颌前方牵引治疗,研究组采用上颌前方牵引联合上颌唇挡治疗。比较两组治疗前后的蝶鞍点-鼻根点-上齿槽座点所构夹角(SNA)、上齿槽座点-鼻根点-下齿槽座点所构夹角(ANB)、前鼻嵴点与颏下点间距(ANS-Me)、上中切牙长轴与前颅底平面所构夹角(U1-SN)、蝶鞍点-鼻根点-下齿槽座点所构夹角(SNB),颞下颌关节关节前、上、后间隙及关节窝深度。结果两组治疗后的SNA、ANB和U1-SN大于治疗前,且研究组治疗后的SNA、ANB大于参照组,差异有统计学意义(P<0.05)。两组治疗后的前间隙高于治疗前,上间隙、后间隙低于治疗前,差异有统计学意义(P<0.05);两组治疗前后的关节前、上、后间隙,关节窝深度比较,差异无统计学意义(P>0.05)。结论上颌前方牵引联合上颌唇挡矫正上颌发育不足可刺激上颌骨发育,提高矫治效果。Objective To explore the clinical effect of maxillary protraction combined with maxillary labial block in the treatment of maxillary hypoplasia.Methods A total of 60 children with maxillary hypoplasia admitted to Ganzhou Women and Children's Health Care Hospital from March 2021 to May 2022 were selected as the research objects,they were divided into study group and control group by random number table method,with 30 cases in each group.The control group was treated with simple maxillary protraction,the study group was treated with maxillary protraction combined with maxillary labial block.The included angle of sella-nasion-subspinale(SNA),the included angle of subspinale-nasion-supramental(ANB),the distance between the anterior nasal spine and the menton(ANS-Me),the angle between the long axis of the upper central incisor and the SN plane(U1-SN),the included angle of sella-nasion-supramentale(SNB),the the anterior,superior and posterior space of temporomandibular joint and the depth of joint fossa were compared between the two groups before and after treatment.Results The SNA,ANB and U1-SN of the two groups after treatment were greater than those before treatment,the SNA and ANB of the study group after treatment were greater than those of the control group,the differences were statistically significant(P<0.05).The anterior joint space after treatment in both groups were higher than those before treatment,while the superior articular space and posterior space were lower than those before treatment,the differences were statistically significant(P<0.05).There were no significant differences in anterior,superior and posterior joint space and fossa depth between the two groups before and after treatment(P>0.05).Conclusion Maxillary protraction combined with maxillary labial block can stimulate maxillary development and improve the therapeutic effect.
