Abstract
[Abstract] Objective: To assess individual’s preference, symptoms and compliance between habitual use of Provox XtraFlow and the combination of Provox XtraFlow during the day and Provox Luna during the night for heat and moisture exchanger therapy in laryngectomized patients. Methods: Open randomized crossover trial for 25 days. After this first follow-up and a 5 days wash-out period, a treatment switching was performed for another 25 days. Results: A total of 28 subjects, were enrolled. Differences were found (p=0.009) in the incidence of dermatological problems with XtraFlow (46.4%) versus Provox Luna (14.3%), as well as in the need to abandon the use of adhesives (46.4%vs.10.7%; p=0.003). The 60.7% of the patients referred the Provox Luna system as their preference for heat and moisture exchanger therapy. Conclusions: The Provox Luna system is a viable additive to heat and moisture exchanger therapy, especially in the setting of compliance concerns and in subjects who desire dermatological relief overnight.
