New neonatal classification of unilateral cleft lip and palate part 2: to predict permanent lateral incisor agenesis and maxillary growth.

Abstract：

:Objectives : To bring a neonatal classification system of unilateral cleft lip and palate and to correlate this classification with the distribution of the permanent lateral incisor and maxillary growth. Design : Retrospective with longitudinal follow-up. Setting : Tertiary. Patients : A total of 112 individuals with treated unilateral cleft lip and palate and 30 controls. Main Outcome Measures : Unilateral cleft lip and palate neonatal casts were classified anatomically in four categories, in which Class 1 corresponds to a maxillary arch with a narrow alveolar cleft; Class 2 corresponds to a balanced form; Class 3 corresponds to a wide cleft and short maxilla; and Class 4 corresponds to a wide cleft and long maxilla. The classification was correlated with the distribution of the permanent lateral incisor. Maxillary growth was evaluated using a cephalometric analysis after the age of 10 years. Results : Clinical classification of unilateral cleft lip and palate found 10 cases of Class 1 (8.9%), 34 cases of Class 2 (30.4%), 46 cases of Class 3 (41.1%), and 22 cases of Class 4 (19.6%). The permanent lateral incisor was most often present in narrower clefts (Classes 1 and 2); whereas, large clefts (Classes 3 and 4) were relatively more frequently associated with an agenesis of the permanent lateral incisor (P = .019). Maxillary growth impairment was most severe in Class 3, with a mean sella-nasion-A point angle at 71.9° ± 4.6° (P < .001). Conclusions : Using the cleft width, arch form, and shape of the nasal septum, unilateral cleft lip and palate can be classified into four different classes at birth, which can all give information about permanent lateral incisor agenesis and maxillary growth.
