Abstract

BACKGROUND

Maxillary expansion is a common orthodontic procedure that could have a positive effect also on airway patency. The aim of the present study was to evaluate the long-term effects of rapid maxillary expansion (RME) on nasopharyngeal area and cranio-cervical angulation in growing patients, compared to controls treated with a function-generating bite appliance (FGB).

MATERIAL AND METHODS

Sixty patients aged 6-14 consecutively treated with RME or FGB were selected retrospectively and divided into two groups. Lateral cephalograms taken before and after treatment were retrieved, and the nasopharyngeal area, delimited superiorly by a sella-posterior nasal spine (PNS) line and inferiorly by a basion-PNS line, and the cranio-cervical angulation were measured.

RESULTS

The mean observation time was 17.6 ± 8 months. No differences were present between the two groups regarding age and gender. The nasopharyngeal area increased significantly in both groups after treatment, but with no statistically significant difference between them. The cranio-cervical angulation showed no differences within or between groups.

CONCLUSIONS

Maxillary deficiency treatment with either RME or FGB was followed by a comparable increase in nasopharyngeal area. Rapid maxillary expansion, Airway, Nasopharyngeal area, Adenoid.

摘要

背景

上颌扩弓是一种常见的正畸治疗方法，对气道通畅性也可能有积极影响。本研究的目的是评估快速上颌扩弓（RME）对生长发育期患者鼻咽部区域和颅颈角度的长期影响，并与使用功能矫治器（FGB）治疗的对照组进行比较。

材料与方法

回顾性选取60例年龄在6 - 14岁之间接受RME或FGB治疗的患者，并将其分为两组。收集治疗前后的头颅侧位片，测量鼻咽部区域（上界为蝶鞍 - 后鼻棘（PNS）线，下界为颅底点 - PNS线）以及颅颈角度。

结果

平均观察时间为17.6 ± 8个月。两组在年龄和性别方面无差异。治疗后两组的鼻咽部区域均显著增加，但两组之间无统计学显著差异。颅颈角度在组内和组间均无差异。

结论

采用RME或FGB治疗上颌骨发育不足后，鼻咽部区域有类似的增加。快速上颌扩弓、气道、鼻咽部区域、腺样体
