Evaluación longitudinal de cráneo en caninos braquicéfalos sin pedigree mediante la técnica de radiografía

Abstract

The primary objective of this study was to analyze the cranial morphological changes in non-pedigreed brachycephalic dogs and to identify the incidence of respiratory disorders. Consequently, this study was conducted using a longitudinal approach, with a census of 30 canine patients older than one year, including both males and females. An imaging assessment was performed using two radiographic views: laterolateral and craniodorsoventral. Furthermore, the investigation focused on morphometric measurements obtained with Fiji software, enabling evaluation of cranial morphometric characteristics and their changes over time. Additionally, a tracheal morphometric analysis was performed in some patients to assess possible morphological abnormalities associated with respiratory collapse. Finally, the study aimed to contribute to clinical diagnosis by identifying the early respiratory conditions affecting these patients, such as brachycephalic obstructive airway syndrome (BOAS).
