CLASSIFICATION FOR CLEFT LIP AND PALATE Veau Classification LAHSHAL Classification Kernahan and Stark Classification
VEAU CLASSIFICATION VEAU 1931DESCRIPTION Group I (A)Defects of the soft palate only Group II (B)Defects involving the hard palate and soft palate extending not further than the incisive foramen. Group III (C)Complete unilateral cleft, extending from the soft palate to the alveolus, usually involving the lip Group IV (D)Complete bilateral clefts, resembles Group III but is bilateral. When cleft is bilateral, pre-maxilla is suspended from the nasal septum. Limitation: isolated cleft lips were not involved in any of group
LAHSHAL CLASSIFICATION Proposed by Kreins O. L = Lip (right) A = Alveolus (right) H = Hard Palate (right) S = Soft Palate (median) H = Hard Palate (left) A = Alveolus (left) L = Lip (left)
capital letter indicates complete cleft (LAHSHAL) small letter indicates incomplete cleft (lahshal) No cleft is represented with a dot (.) EXAMPLES: Bilateral complete cleft lip and palate = LAHSHAL Left complete cleft lip = L Right incomplete cleft lip and alveolus = la.....
KERNAHAN AND STARK CLASSIFICATION Embryology-based classification system proposed in 1958 that designates the incisive foramen as the dividing line between the primary and secondary palates. Primary palate includes those structures anterior to the incisive foramen (lip, pre- maxilla, anterior septum). Secondary palate includes those structures posterior to the incisive foramen (lateral palatine shelves, soft palate, and uvula).
Areas 1 and 4 – Lip Areas 2 and 5 – Alveolus Areas 3 and 6 – Primary Palate Areas 7 and 8 - Hard palate Area 9 - Soft palate
