The Passy\u2010Muir valve enables phonation by redirecting exhaled air via the glottis. Poor tolerance of the Passy\u2010Muir valve is associated with excessive transtracheal pressures on exhalation due to upper airway obstruction. Drilling a small hole in the side of the Passy\u2010Muir valve creates a pressure relief port to allow partial exhalation through the tracheostomy tube while enabling phonation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design:<\/jats:title><jats:p>A retrospective case series is presented of 10 aphonic pediatric patients with a tracheostomy trialed with a drilled Passy\u2010Muir valve.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods:<\/jats:title><jats:p>Valve tolerance was assessed clinically and objectively. Handheld manometry was used to determine transtracheal pressures on passive exhalation. All patients had a diagnosis of upper airway obstruction and demonstrated excessive pressures wearing a standard Passy\u2010Muir valve. Patients were assessed wearing a Passy\u2010Muir valve with up to two 1.6\u2010mm holes drilled in the side of the valve.
