Effects Of Miniscrew-assisted Rapid Palatal Expander On Nasal Septum Deviation
Objectives: Nasal septum deviation can present with airflow obstruction and lead to a diminished lifestyle. Severe cases can require surgical treatments such as septoplasty or rhinoplasty and complications can arise. The midpalatal junction and roof the mouth can potentially affect the anatomy of the nasal cavity such as the nasal airway width. Through maxillary expansion, the miniscrew-assisted rapid palatal expander can expand the nasal floor and increase the transverse dimension of the nasal cavity, thereby rectifying nasal septum deviation.
In essence, this study will evaluate preoperative and postoperative parameters of the septum and evaluate MARPE as an applicable treatment modality for nasal septum deviation.
Methods: Following Institutional Review Board approval at UCLA, a prospective cohort study included subjects undergoing MARPE from January 2014 to June 2018 with available before and after expansion cone beam computed tomography in an orthodontic office setting. 29 patients (16 females and 13 males) met the inclusion criteria. The nasal airway width and nasal septum deviation was measured using Invivo6 ™ Software (version 6.0.3). Inter-rated reliability of all pre- and post-expansion parameters was measured. Significant changes in the nasal septal deviation was evaluated using paired T-test with significance set at p-value <0.05.
Results: Of the 29 patients, 21 patients showed a decrease in nasal septum deviation. All variables tested had a significant change (P<0.005). Nasal airway width increased by a mean of 1.51mm. Septal deviation decreased by a mean of 0.27 ± 0.66mm.
Conclusions: MARPE can aid in correcting nasal septum deviation.
