Plain-English summary
A group of adult Beagle dogs with vocal fold issues was studied to understand how their bodies compensated for the loss of function in one vocal fold. The dogs were divided into groups based on their specific vocal fold problems, and scans were taken to measure the metabolism of the vocal folds. Results showed that the healthy vocal fold on the opposite side was working harder and had increased metabolic activity compared to the impaired fold. This suggests that when one vocal fold is not functioning properly, the other may compensate by becoming more active, which could affect the quality of their barking.

Abstract
OBJECTIVE: To explore the glycolytic metabolism of contralateral vocal fold compensation by examining the glycolytic metabolism of the posterior region of vocal folds in beagles with unilateral vocal fold immobility disorders and its correlation with acoustic parameters. STUDY DESIGN: Prospective animal study. SETTING: Department of Voice METHODS: Ten adult beagles were divided randomly into three groups: a unilateral cricoarytenoid joint dislocation (UCAJD) group (n = 4), a unilateral vocal fold paralysis (UVFP) group (n = 4), and a control group (n = 2). Positron emission tomography-computed tomography (PET/CT) scans of larynx and recordings of vocalizations were collected 4 months after the operations. The maximum standardized uptake values (SUVmax) of 18F-FDG within each posterior region of the vocal folds were obtained from PET/CT and voice recordings were analyzed for acoustic parameters F0, jitter, shimmer, and loudness using PRAAT. RESULTS: In both UCAJD and UVFP groups, a significant increase of SUVmax was observed in the contralateral vocal fold relative to the impaired fold (P < 0.05). The SUVmax values of the contralateral vocal folds and the SUVmax values of the impaired vocal folds in the UCAJD, UVFP, and control groups were both found to be significantly different (P < 0.05). The SUVmax of the contralateral vocal fold may exhibit a potentially negative correlation with jitter and shimmer, with R2 values of 0.42 and 0.26 and P values of 0.03 and 0.11, respectively. CONCLUSION: UCAJD and UVFP can cause enhanced glycolytic metabolism of the contralateral vocal fold relative to the impaired vocal fold. The SUVmax of the contralateral vocal fold may be positively correlated with acoustic quality.
