AVILES-GALAZ, Juan Luis; LINCOVIL-NANCO, Pamela Odet  y  VASQUEZ-HUERTA, Alex. Effects of Rapid Maxillary Expansion on Nasal Airflow of Patients Between 6 and 14 Years of Age, with Maxillary Compression, Measured with a Portable Nasal Flowmeter. Int. J. Odontostomat. [online]. 2020, vol.14, n.3, pp.380-386. ISSN 0718-381X.  http://dx.doi.org/10.4067/S0718-381X2020000300380.

The objective of our simple prospective longitudinal type study of repeated measures, was to determine the variation of nasal airflow measured with a portable nasal flow meter, in children between 6 and 14 years of age with maxillary compression, after rapid maxillary expansion (RME). The study consisted of 16 children diagnosed with maxillary compression and those who were identified with a rapid maxillary disjunction. The values of the amount of expansion were recorded and the measurement of the peak nasal inspiratory flow (PNIF) was performed before the ERM (T1), immediately after (T2) and after 3 months of retention period (T3), maintaining the same initial conditions. Results: the value maximum and average measurements of FINM in T2 were greater than in T1 (p-value, 0.0056) and (p-value 0.0062) respectively, while between T2 and T3 there were no differences (p value: 0.3021) and (p value: 0.3315) respectively. There is a significant increase in PNIF values immediately after rapid maxillary expansion that is in a period of 3 months.

Palabras clave : rapid maxillary expansion; peak nasal inspiratory flow; maxillary compression.
