Abstract

Objectives: To evaluate the functional outcomes in patients using the Montgomery^® cannula across three domains: (1) Respiration, assessed through Stomal Occlusion Adaptation Stages; (2) Phonation, based on patient-reported communication levels; and (3) Swallowing, based on the presence of clinical symptoms. Methods: A retrospective case series was conducted on 18 patients who received a Montgomery^® Long-Term Cannula at the University Medical Center Ho Chi Minh City from July 2023 to July 2025. Clinical data were collected from medical records, and functional data were gathered through telephone interviews using predefined scales. Results: The study included 18 patients (61.1% female), with a mean age of 65.0 ± 14.38 years. Regarding respiratory function, 9 of 18 patients (50.0%) achieved Stage 5 (successful decannulation), while 7 of 18 patients (38.9%) were in active stages of capping trials (Stages 1-3). The median time to successful decannulation was 2.5 months. Among 16 evaluable patients for functional outcomes, 10 (62.5%) reported a "comfortable communication" level, and 3 (18.8%) experienced symptoms of dysphagia and/or food impaction sensation. Conclusion: The Montgomery^® cannula provides significant improvements in respiratory and phonation functions for the majority of patients, serving as a valuable tool in the rehabilitative pathway toward tracheostomy decannulation. Swallowing issues persist in a subset of patients, suggesting the need for specialized swallowing rehabilitation interventions.
