Cul de Sac Resonance • Voice sounds muffled and low in volume • Sound is absorbed (like a sponge) in the cavity Cul de Sac Resonance Types and Causes • Oral cul de sac resonance • Nasal cul de sac resonance • Pharyngeal cul de sac resonance 10
Oral Cul de Sac Resonance • Sound is mostly in the oral cavity • Due to small oral cavity size or small mouth opening (microstomia) • Parents describe speech as “mumbling” (which is not opening the mouth very much) Nasal Cul de Sac Resonance • Sound is mostly in the nasal cavity • Due to VPI and nasal obstruction from: – a deviated septum – stenotic nares – maxillary retrusion • Common with cleft palate and craniofacial anomalies 11
