Effective retropulsion and centralization of the severely malpositioned premaxilla in patients with bilateral cleft lip and palate: A novel modified presurgical nasoalveolar molding device with retraction screw

摘要

Purpose: A novel, modified presurgical nasoalveolar molding (MPNAM) device with retraction screw was designed and used in patients with bilateral complete cleft lip and palate (BCCLP) to rapidly retract and centralize the protuberant and malpositioned premaxilla and correct the nasolabial and palatal deformities. The orthopedic effects and possible complications were evaluated.
