Evaluación del volumen de la vía aérea superior mediante tomografía computarizada de haz cónico en pacientes adultos atendidos en un centro de radiología maxilofacial de Lima

Abstract

Objective: The aim of this study was determinate the volume of upper airway in adults treated at a maxillofacial radiology center in Lima,Perú. Methods: A cross-secional descriptive study, 203 cone beam computed thomography (CBCT) of adult patients aged 18-75 years were collected from the database of a maxillofacial radiology center. Thomographys were visualized throught the Planmeca Romexis® program. A mesurement with validated plans was used. A measurement with plans validated by Guijarro R et al, 2013 was used. In the sagittal, transverse and coronal sense for the measurement of the nasopharyngeal and oropharyngeal airway. The volumes measured were nasopharynx, oropharyngeal and total volume. To evaluate them according to gender and age, the Mann-Whitney U tests were performed, Kruskall Wallis respectively. Results: 52% were male, mean age was 29.7 years [18-75 years]. The mean volumes for the nasopharynx, oropharynx and total volume for the male gender were 8.19 cm3, 16.96 cm3, 25.15 cm3 and for the female gender it was 7.23 cm3, 13.99 cm3 and 21, 21 cm3 respectively. The males had 3.94 cm3 more with respect to the total volume of the women p <0.001. Conclusions: The total airway volumes of the study population were 25.15 cm3 for males and 21.21 cm3 for females.
