Cleft Lip Surgery Secondary Unilateral Cleft Lip Surgery Secondary Deformity “The best effort of any surgeon at primary reconstruction of a hare-lip … [will] usually leave some deformity” Gillies and Kilner, Lancet 1932 Secondary Deformity § §

Secondary deformities are the rule rather than the exception, and in many aspects are more difficult to repair than primary deformities It is easier to avoid a secondary deformity than it is to correct it

Lip Deformities § § § § § §

Vertical excess Vertical deficiency Horizontal deficiency Vermillion Whistle deformity Scars

Vertical Excess § § §

Various degrees of elliptical skin excisions Only seen in unilateral cleft lip May need to re-advance repair

Timing of Secondary Revisions § § § §

Preschool years (age 4-5) Early adolescence Cessation of facial growth Emotional maturity


Vermillion Deficiency (Whistle deformity) Cause: Deficiency of muscle and mucosa Treatment: §

Mild Re-Do repairLocal tissue rearrangement (Re do repair) Z-plasties, re-advancement Reconstitute orbicularis Fat augmentation

§

Severe Abbe Flap

Vermillion Deformity Correction § § § §

Maintain tubercle pout Realign red line, mucocutaneous junction V-Y advancements, Zplasties Fat injections: mixed results


Vermilion Misalignment Z plasty rearrangement of white roll vermilion border to correct malalignment and scar contracture limited to white roll

Lip Scar § §

Most noticeable and striking stigmata Contributing factors § Orbicularis § Premaxilla § Cleft width § Extreme tension

Orbicularis Oris Muscle § §

§

Continuity cannot be overemphasized Implicated in: § Widened lip scar § Wide and convex philtrum § Whistle deformity § Lateral bulging with animation Repair muscle to establish continuity

Philtrum § § §

Keystone of the upper lip Progressively wide and convex Orbicularis oris and tension from repair Treatment Goals: § Excision of excess tissue § Reapproximation of orbicularis muscle § Scars simulating philtral


Philtral Column Reconstruction

Horizontal Deficiency Abbe Flap § § § § §

Lower lip transfer to deficient upper lip “Lip switch” More severe deformities Highly versatile Balances mouth


Cleft Nose Deformity § § §

At time of lip repair Undermine nasal skin, resuspend alar cartilage Recurrence possible

Pre-school age §

Columella

Adolescence §

Definitive rhinoplasty


Alveolar cleft § § § §

Ideal time: period of mixed dentition before eruption of canine 6-12 years old Erupting tooth induces alveolar bone generation Alveolar bone graft

Alveolar Bone Grafting: Function § Stabilize arches & teeth § Allow tooth movement into cleft § Close oronasal fistula Support alar base

Standard method of bridging alveolar clefts § § § § § § §

Iliac crest bone graft Followed by orthodontic tooth movement into cleft Ideal time for bone graf Period of mixed dentition When maxillary incisors visible, not yet erupted Before canines erupted (6-12 years old) Erupting tooth induces alveolar bone generation


Orthognathics

Hypoplastic Maxilla

Typical Stigmata § § §

Class III occlusion Protruding lower lip Flattened nasal tip Orthodontist and Maxillofacial surgeon

Le Fort I Osteotomy Maxillary Advancement-Maxillary or midface advancement is achieved using distraction osteogenesis techniques, and the results are often dramatic in improving occlusion and aesthetic balance to the face

Maxillary Distraction
