Management of Constricted Upper Arch and Protruded Premaxilla in a 2-Year-old Patient with Unrepaired BCLP.

The paper presented the treatment procedure of a 2-year-old patient with unrepaired bilateral cleft lip and palate (BCLP). Complicated situation included severely protruded premaxilla and constricted upper dental arch, possibly related to delayed treatment of cleft lip and palate. Orthodontic expansion lasted for 8 months, including using fan-type expander for 3 months. After that, premaxillary osteotomy was performed to reset the premaxilla, and 4 months later, simultaneous repair of cleft lip and palate was taken. Follow-up evaluation in 5.5 years revealed acceptable language development and craniofacial profile, and maxillary growth was satisfactory. The treatment procedure of this patient provided an exploratory protocol for those patients with unrepaired BCLP who suffered from deteriorated preaxillary protrusion and constricted upper arch.
