: To investigate the long-term effects of maxillary skeletal expander (MSE) treatment on functional breathing.
measures of breathing, the peak nasal inspiratory flow (PNIF), and peak oral inspiratory flow (POIF), and subjective measures of breathing, the visual analog scale (VAS) and nasal obstruction symptom evaluation (NOSE) survey, were used to investigate the long-term effects of MSE in functional breathing. Seventeen patients, mean age 19.4 ± 3.9 years treated at the UCLA Orthodontics Clinic were assessed on their functional breathing at 3 timepoints: pre-expansion (T0), post-expansion (T1), and post-orthodontic treatment (T2).
: Immediately after expansion (T1), all the objective functional breathing values were significantly increased in comparison to T0 ( < 0.05). The VAS total, VAS right and VAS left were significantly lower at T1 in comparison to T0 ( < 0.05). At 26.8 ± 3.9 months after MSE expansion (T2), PNIF total, PNIF right, PNIF left, and POIF were significantly higher when compared to T0 ( < 0.05). Also, VAS total, VAS right and VAS left were significantly lower at T2 when compared to T0 ( < 0.05). Additionally, there was a positive correlation between PNIF and the magnitude of expansion at anterior nasal spine and zygomaticomaxillary point (ZMA). There was a positive correlation between total VAS and the magnitude of expansion at the ZMA. There were no significant changes for the NOSE subjective breathing measurement at all time comparisons.
: Overall, MSE treatment produces an increased objective and subjective airway improvement that continues to remain stable in the long-term post expansion.
研究上颌骨扩弓器（MSE）治疗对功能性呼吸的长期影响。
采用呼吸测量指标，即鼻吸气峰值流速（PNIF）和口吸气峰值流速（POIF），以及呼吸主观测量指标，即视觉模拟量表（VAS）和鼻阻塞症状评估（NOSE）问卷，来研究MSE对功能性呼吸的长期影响。对在加州大学洛杉矶分校正畸诊所接受治疗的17名平均年龄为19.4±3.9岁的患者，在3个时间点评估其功能性呼吸情况：扩弓前（T0）、扩弓后（T1）和正畸治疗后（T2）。
扩弓后即刻（T1），与T0相比，所有客观功能性呼吸值均显著增加（P<0.05）。与T0相比，T1时VAS总分、右侧VAS和左侧VAS均显著降低（P<0.05）。在MSE扩弓后26.8±3.9个月（T2）时，与T0相比，PNIF总分、右侧PNIF、左侧PNIF和POIF均显著升高（P<0.05）。此外，与T0相比，T2时VAS总分、右侧VAS和左侧VAS也显著降低（P<0.05）。此外，PNIF与前鼻棘和颧上颌点（ZMA）处的扩弓幅度呈正相关。VAS总分与ZMA处的扩弓幅度呈正相关。在所有时间点比较中，NOSE主观呼吸测量无显著变化。
总体而言，MSE治疗可使气道在客观和主观上得到改善，且在扩弓后的长期内持续保持稳定。
