Clinical Outcomes Utilizing a "Modified Latham" Appliance for Presurgical Infant Orthopedics in Patients With Unilateral Complete Cleft Lip and Palate.

Presurgical infant orthopedic manipulation is utilized prior to cleft lip/nasal repair to facilitate a gingivoperiosteoplasty (GPP) and primary nasolabial repairs. The Latham dentomaxillary advancement appliance uses a screw that must be tightened daily to approximate the cleft segments in unilateral complete clefts. Our cleft center has been utilizing a "modified Latham" appliance since 1987, including an orthodontic elastic power chain to close the gap in a shorter amount of time. We performed a retrospective chart review of all patients undergoing treatment at Johns Hopkins All Children's Hospital (JHACH) with a unilateral complete cleft lip and palate between 1987 and 2017. Patients were identified by the International Classification of Diseases, Ninth Revision code (749.21). The majority of the patients represent the experience of the senior authors (E.R. and R.F.). Two hundred and eighty-one patients with unilateral complete cleft lip/palate were identified. Seventy-five patients were treated with a "modified Latham" appliance prior to their lip repair. The "modified Latham" appliance remained in place on average 20.6 days (range: 4-82), and average hospital stay after placement was 1.18 days. Nearly 96% of patients underwent a successful GPP at the time of nasolabial repair. Modification of the Latham appliance by utilizing an elastic power chain and eliminating the screw allows rapid closure of the alveolar cleft with limited need for adjustments and outpatient visits. Direct approximation of the palatal segments allows successful completion of a GPP in 95.9% of patients with limited dissection.
