Abstract

Background: Whether Hyrax maxillary expander is an effective treatment for maxillary transverse deficiency as well as expansion of the upper airway is still controversial. The study's purpose was to evaluate 3D changes in upper airway dimensions of adolescent patients measured primarily by cone-beam computed tomography (CBCT) after rapid maxillary expansion (RME) with the Hyrax maxillary expander.

Methods: Studies up to 1 April 2024 were searched in the following databases: PubMed/MEDICINE, Web of Science, Cochrane Library, and Embase. Inclusion criteria were clinical trials and cohort studies that assessed the effect of RME in adolescent patients with upper airway stenosis using CBCT-based three-dimensional analysis. The risk of bias in the study outcomes was assessed using the Cochrane Collaboration's risk of bias tool, the GRADE method, and a tool for evaluating non-randomized controlled study (non-RCT) literature from a previous systematic review, depending on the types of articles. The study was reported in accordance with PRISMA guidelines.

Results: The study conducted a random effects meta-analysis of mean differences and 95% confidence intervals for changes in upper airway volumes, including the nasal cavity (NC), in the outcomes of 16 included studies, followed by subgroup analyses.

Conclusion: A significant increase in nasopharynx volume was observed after rapid maxillary expansion (RME) by Hyrax maxillary expander (MD = 0.69, 95% CI (0.09~1.28), p = 0.02).

Hyrax 上颌骨扩张器对青少年鼻腔和上气道的影响：系统回顾与元分析

背景：Hyrax上颌骨扩张器是否能有效治疗上颌骨横向缺损以及上气道扩张，目前仍存在争议。本研究的目的是评估青少年患者在使用 Hyrax 上颌骨扩张器进行快速上颌骨扩张（RME）后，主要通过锥束计算机断层扫描（CBCT）测量上气道尺寸的三维变化：在以下数据库中搜索了截至 2024 年 4 月 1 日的研究：PubMed/MEDICINE、Web of Science、Cochrane Library 和 Embase。纳入标准是使用基于 CBCT 的三维分析评估 RME 对上气道狭窄的青少年患者的效果的临床试验和队列研究。研究结果的偏倚风险采用 Cochrane 协作组织的偏倚风险工具、GRADE 方法以及先前系统综述中的非随机对照研究（non-RCT）文献评估工具进行评估，具体视文章类型而定。研究报告符合 PRISMA 指南：该研究对纳入的 16 项研究结果中包括鼻腔（NC）在内的上气道容积变化的平均差和 95% 置信区间进行了随机效应荟萃分析，然后进行了亚组分析：结论：使用 Hyrax 上颌骨扩张器进行快速上颌骨扩张（RME）后，鼻咽部体积明显增加（MD = 0.69，95% CI (0.09~1.28)，P = 0.02）。
