The aim of this study was to analyze the variations in nasal dimensions in prepubertal patients associated with RME therapy compared with an untreated age matched control group.
A group of 61 subjects (26 F, 35 M; mean age 10.5±1.8 years) was enrolled in the study to undergo a rapid maxillary expansion therapy; 41 subjects (26 F, 15 M; mean age 10.7±2.2 years) were enrolled as a control group. Both groups underwent nasal soft tissues width measurements using a caliper at three separate time points: T0 - prior to the placement of RME; T1 - after completion of active expansion phase; T2 - at the removal of the expander (nearly 6 months after T1).
The ANOVA showed statistically significant increments (P<0.0001) of the greater alar cartilage (GAC) measurement (0.8±0.2 mm) in the study group, differences for the AB measurements were not statistically significant (P=0.0784).
The treatment of rapid maxillary expansion can induce an increase in GAC soft tissues width of about 1 mm in prepubertal patients. This increase could not be considered of clinical impact. The alar base width increase less than GAC, this increase is without statistical significance.
本研究旨在分析与未接受治疗的年龄匹配对照组相比，青春期前接受快速上颌扩弓治疗（RME）患者的鼻腔尺寸变化。
一组61名受试者（26名女性，35名男性；平均年龄10.5±1.8岁）被纳入本研究以接受快速上颌扩弓治疗；41名受试者（26名女性，15名男性；平均年龄10.7±2.2岁）被纳入作为对照组。两组均在三个不同时间点使用卡尺测量鼻腔软组织宽度：T0 - 放置RME之前；T1 - 主动扩弓阶段完成后；T2 - 去除扩弓器时（T1后近6个月）。
方差分析显示，研究组大翼软骨（GAC）测量值有统计学意义的增加（P<0.0001）（0.8±0.2毫米），鼻翼基底（AB）测量值的差异无统计学意义（P=0.0784）。
快速上颌扩弓治疗可使青春期前患者的GAC软组织宽度增加约1毫米。这种增加不具有临床意义。鼻翼基底宽度的增加小于GAC，且这种增加无统计学意义。
