Fellowship topic on cleft lip and palate: the embryologic origin in the failure of fusion of the frontonasal, maxillary and mandibular processes and of the palatal shelves; the Veau and Kernahan classifications from an isolated cleft lip through a complete bilateral cleft lip and palate; the newborn priorities of feeding with a squeeze bottle or specialised teat and not allowing aspiration or failure to thrive, the near-universal otitis media with effusion from Eustachian tube dysfunction and the role of grommets at palatoplasty; Pierre Robin sequence with micrognathia, glossoptosis and airway obstruction; the staged surgical timeline of primary lip repair around three months by the rule of ten, palatal repair at nine to eighteen months, secondary alveolar bone grafting at nine to eleven years and orthognathic correction in adolescence; nasoalveolar molding in the first weeks; the syndromic associations of Van der Woude, Stickler and 22q11 deletion; and the multidisciplinary cleft team coordinating surgery, orthodontics, speech, audiology, genetics and psychology across childhood.

A newborn with a cleft palate and a small recessed chin (micrognathia) has Pierre Robin sequence until proven otherwise and the tongue base can obstruct the airway, especially when supine; prone positioning, a nasopharyngeal airway or in severe cases mandibular distraction may be needed to protect the airwayAn infant with a cleft palate who is choking, coughing or having milk come through the nose during feeding is at risk of aspiration; the feeding technique must be changed immediately to an upright position with a squeeze bottle or specialised cleft teat and paced feeding, and persistent nasal regurgitation or respiratory distress warrants urgent reassessmentA newborn with a cleft palate and feeding difficulty who is losing weight or not meeting growth milestones needs urgent dietetic and cleft-team input because failure to thrive delays surgical repair and compounds morbidityA child with a cleft and a heart murmur, hypocalcaemia or immunodeficiency may have 22q11 deletion syndrome and needs urgent genetics, cardiac and calcium evaluation because the airway and cardiac lesions can be life-threateningBilateral cleft lip and palate with a protruding premaxilla can obstruct the nasal airway and distort feeding, and it needs early nasoalveolar molding and cleft-team review rather than reassurance that the lip will be repaired later

Overview & Definition

Picture a baby born in the delivery suite whose midwife notices a split in the upper lip as she dries the child — perhaps just a small notch, perhaps a gap running up into the nostril, and when the baby cries the palate is open too. The parents are frightened and full of questions the general paediatrician must answer on the spot: will the baby feed, will the baby be deaf, when can it be fixed. This is the everyday face of orofacial clefting, and the skill is not in spotting the gap, which is obvious, but in three judgements made in the first hours of life. Can this baby feed safely without choking or aspirating, and what bottle and technique do you teach the mother today? Is the airway safe, because a cleft palate with a small chin can hide a Pierre Robin sequence that obstructs when supine? And is this an isolated cleft or the face of a syndrome — 22q11 deletion, Stickler or Van der Woude — that changes the whole work-up and the genetic counselling? [2] [3]

An orofacial cleft is a structural gap in the upper lip, the alveolus (the tooth-bearing gum), the hard palate or the soft palate, produced when the embryonic facial processes or the palatal shelves fail to meet and fuse during the first trimester. The gap may be as small as a bifid uvula — the mildest palatal cleft, often found only when a child is investigated for nasal-sounding speech — or as large as a complete bilateral cleft lip and palate in which both sides of the lip, the alveolus and the entire palate are open and the central premaxilla protrudes. Most clefts are visible at birth, but an isolated submucous cleft palate, where the mucosa is intact but the muscles of the soft palate are split in the midline, can be missed until the child presents with hypernasal speech or persistent middle-ear effusion. [1] [3]

The reason cleft lip and palate travel together yet are distinct is embryologic. The lip and the alveolus form first, from the fusion of the medial nasal prominence (a derivative of the frontonasal process) with the maxillary process around the sixth week. The palate forms later, in two stages: the primary palate (the anterior third, behind the upper incisors) fuses with the maxillary processes by about the seventh week, and then the two palatal shelves — tongue-shaped outgrowths of the maxillary processes — reorient from a vertical position on either side of the tongue to a horizontal plane above it and fuse in the midline and with the nasal septum by the ninth to twelfth week. Because the lip forms before the palate, a cleft lip can occur with or without a cleft palate, but an isolated cleft palate has a different embryologic mechanism and a different epidemiology and genetic risk.
