Purpose:
The aim of this study was to characterize the normal sonographic anatomy of the soft palate in dogs.
Materials And Methods:
The study was performed on seven canine heads via a submental and intraoral approach. The detected anatomical structures were then reexamined via a submental approach in a water bath. Each anatomic layer was subsequently dissected starting with the submental layers and working towards the soft palate. After every preparation a sonographic examination was carried out.
Results:
Differentiation between the soft palate and the surrounding oropharyngeal tissue can be effectively achieved. Using the submental approach, the transition between hard palate and soft palate as well as the middle section of the soft palate were distinguished from other oropharyngeal structures in all cases. Visualization of the caudal part of the velum and evaluation of the echogenicity of the soft palate were difficult and not always possible. In the two brachycephalic dogs of the study, it was challenging to distinguish the soft palate from the surrounding tissue.
Conclusion:
The sonographic appearance of the canine soft palate in cadavers was described in this study. The submental approach allows differentiation between intraoral structures. Evaluation of the echogenicity and length of the soft palate is limited.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
