ABSTRACT

SUMMARY:

Clinically, avian medicine still finds it very difficult to treat wild patients due to the lack of reliable information about their anatomy and physiological parameters that make comparative analyzes possible. Considering that computed tomography (CT) is one of the most viable alternatives in radiography of the head, we describe the comparative anatomy of the beak in the Ara ararauna and the Ramphastos toco through this imaging modality and macroscopy analysis, providing additional information about their conformation and topography for clinical exams. Adult specimens of each were dissected after the CT and beaks were removed for macroscopic analyses. The macroscopic and tomographic findings for both species confirm the similarities in beak morphology and the dietary peculiarities of each.The CT scan proved to be a useful tool to visualize internal structures of the skull through a detailed virtopsy of regions that are difficult to access by the usual necropsy with a scalpel.
RESUMEN
RESUMEN Debido a la escasa información de la anatomía y de los parámetros fisiológicos que hacen posible los análisis comparativos en la medicina aviar, clínicamente resulta muy difícil el tratamiento de estos animales. Considerando que la tomografía computarizada es una buena alternativa, estudiamos la anatomía comparativa del pico en Ara ararauna y Toco Toucan utilizando imágenes y un análisis de macroscopía. Estos métodos proporcionaron información adicional referente a su conformación y topografía para el trabajo clínico. Después de analizar la tomografía se disecaron las muestras de especímenes adultos y se retiraron los picos para un análisis macroscópico. Los hallazgos macroscópicos y tomográficos para ambas especies corroboraron la relación morfológica entre los picos y las peculiaridades dietéticas de cada uno. Se demostró además, que la tomografía computarizada es una herramienta útil para visualizar las estructuras internas del cráneo de las aves, a través de una virtopsia detallada en áreas de difícil acceso durante una necropsia habitual.
