Abstract
Objective: To evaluate endoscopy for detection of epithelial remnants within the feline tympanic bulla following ventral bulla osteotomy (VBO) and to report the most likely locations within the bulla for epithelial remnants to occur.
Methods: This was a single-center experimental cadaveric study. 10 VBO procedures were performed by 5 board-certified surgeons in 5 feline cadavers. Following completion, a 1.9-mm, 30° rigid endoscope was inserted into the rostral, caudal, dorsal, lateral, and medial section, and images were acquired. A blinded observer evaluated the endoscopic images for epithelial remnants, and the percentage of the section containing epithelial remnants was measured. The mean and SD of distribution of epithelial remnants were calculated for each section.
Results: Remnant epithelium was noted in at least 1 section in each cadaver. The dorsal section was the most common to have epithelial remnants identified (10 of 10), whereas the lateral (5 of 10) and medial (5 of 10) were the least common. The lateral section contained the most epithelial remnants (6.9 ± 11.42%), whereas the caudal section contained the least (1.2 ± 1.42%).
Conclusions: The use of a 1.9-mm, 30° endoscope was feasible for evaluation and identification of epithelial remnants in a feline tympanic bulla following VBO. Epithelial remnants were consistently identified in all sections with endoscopic assistance.
Clinical relevance: Endoscopy following completion of a VBO may be considered to ensure complete removal of epithelium.
期刊介绍：
The American Journal of Veterinary Research supports the collaborative exchange of information between researchers and clinicians by publishing novel research findings that bridge the gulf between basic research and clinical practice or that help to translate laboratory research and preclinical studies to the development of clinical trials and clinical practice. The journal welcomes submission of high-quality original studies and review articles in a wide range of scientific fields, including anatomy, anesthesiology, animal welfare, behavior, epidemiology, genetics, heredity, infectious disease, molecular biology, oncology, pharmacology, pathogenic mechanisms, physiology, surgery, theriogenology, toxicology, and vaccinology. Species of interest include production animals, companion animals, equids, exotic animals, birds, reptiles, and wild and marine animals. Reports of laboratory animal studies and studies involving the use of animals as experimental models of human diseases are considered only when the study results are of demonstrable benefit to the species used in the research or to another species of veterinary interest. Other fields of interest or animals species are not necessarily excluded from consideration, but such reports must focus on novel research findings. Submitted papers must make an original and substantial contribution to the veterinary medicine knowledge base; preliminary studies are not appropriate.
