Plain-English summary
A group of dogs with tumors in their larynx underwent surgery to remove the growths and assess how it affected their vocal function and breathing. While the surgery successfully healed the area and kept the airway open, dogs that had more extensive tissue removed experienced significant vocal impairment. Most dogs lost some weight shortly after surgery but regained it by the end of the month. This study highlights the importance of balancing effective tumor removal with the preservation of vocal function in dogs undergoing laryngeal surgery.

Abstract
<h4>Background and objectives</h4>Evaluate the feasibility and functional outcomes of extended transoral resection for anterior commissure (AC) tumors in canines, focusing on laryngeal framework, airway, and vocal function.<h4>Methods</h4>Twelve dogs underwent endoscopic partial thyroid cartilage resection, randomized into: Group A (AC + adjacent cartilage), Group B (AC + left vocal cord anterior 1/3), Group C (AC + bilateral vocal cord anterior 1/3). Outcomes assessed included laryngoscopic healing, CT-measured laminal angle (LA) and glottal area (GA), weight, and GRBAS vocal scores.<h4>Results</h4>The wound healed and epithelized in 4 weeks. Postoperative LA significantly decreased in all groups (<i>p</i> ≤ 0.010), with the largest reduction in Group C (<i>p</i> ≤ 0.030 vs. A/B). LA reduction ratio correlated with resected midline height (RMH) (<i>r</i> = 0.546, <i>p</i> = 0.041) rather than resection factors of width and area. GA remained stable. Group C showed severe vocal impairment (GRBAS 8.67 ± 0.58 vs. 5.63 ± 0.48 in A, <i>p</i> = 0.008). Weight transiently decreased at day 7 but recovered by day 35.<h4>Conclusion</h4>Extended transoral resection effectively removes AC lesions while preserving airway dimensions. However, extensive resection causes significant vocal dysfunction, highlighting the balance between oncologic radicality and function preservation. The potential LA-RMH correlation reveals the stabilizing characteristics of cartilaginous structures, offering preclinical insights for optimizing AC cancer surgery.
