  • Title: Does Nasal Cavity Enlargement Associated With Respiratory Function Improvement After Surgically Assisted Rapid Maxillary Expansion?
    Author: Liu K, Wei H, Dai J, Wang X.
    Journal: J Craniofac Surg; 2020; 31(3):829-831. PubMed ID: 32068729.
    Abstract:
    PURPOSE: To systematically evaluate the effects of surgically assisted rapid maxillary expansion (SARME) on nasal cavity and its associated respiratory function changes. MATERIAL AND METHODS: Multiple electronic databases were searched, authors were contacted as required, and reference lists of potentially relevant studies were screened. Articles that included patients older than 16 who had received SARME were considered. Data extraction and quality assessment were performed independently and in duplicate. RESULTS: Eight articles, including 161 patients, were finally selected and analyzed. Nasal cavity significantly augmentation after SARME has been recognized by 7 studies with moderate-quality evidence. Among them, the nasal cavity volume increased <20% in 4 studies, 20% to 40% in 1 study, and >40% in 2 studies. Totally, the range of increasing in nasal cavity volume was 7.6% to 99%. One study had recorded the nasal expiratory and inspiratory flow significantly increased 18.5% and 21.7%, respectively. CONCLUSION: SARME was found to produce meaningful volume augmentation in nasal cavity with adult patients. However, the improvement of nasal respiratory function has not been well elucidated; thus, SARME is not yet recommended for the purpose of improving nasal respiratory.
