 In recent years, the number of infants who undergo tracheostomy in the neonatal and infant period has been increasing with the development of perinatal medicine and pediatric anesthesia. The use of a speaking valve (speech valve:SV) is expected to promote speech and language development and improve the quality of life of children with tracheostomy. For children who have difficulty wearing an SV, it has been proposed to drill a hole in the SV to reduce subglottal pressure and make the SV easier to wear. In this paper, we report two cases in which speech-language development may have been accelerated by the use of a drilled SV. Both patients increased their intentional speech through wearing the drilled SV, and after improvement in their physical condition and readjustment of the cannula, they were able to wear the SV without a hole on a regular basis. Compared to the SV without a hole, the SV with a hole is less likely to increase intratracheal pressure and is less uncomfortable for young children, and thus it is considered to be effective for gradual SV use. The results also suggest that SV with a hole that allows a portion of the exhaled air to flow out through the tracheostomy hole has a certain effect on speech and language development.
