Early Orthopedic Retraction of the Premaxilla in Bilateral Complete Cleft Lip and Palate: An Innovative Approach to a Difficult Problem

Correction of a prominent premaxilla in a juvenile with a bilateral cleft lip and palate using a novel, hybrid function regulator, the FR-BCPPm, followed by preadjusted fixed appliances: A 20-year follow-up

A seven-year-old boy with a repaired bilateral cleft lip and palate, presented with a severe skeletal II base and an extremely prominent premaxilla. He had grossly incompetent lips with lower lip trapping, an 18.5-mm overjet, a deep overbite, markedly retroclined lower incisors, bilateral crossbites and 12-mm-wide alveolar gaps together with 6-mm vertical steps between the extruded premaxillary incisors and the posterior teeth. Before the eruption of the permanent canines, there was an urgency to approximate the opposing cleft alveolar margins and to level the split maxillary occlusal plane, in order to facilitate the successful insertion and subsequent consolidation of secondary alveolar bone grafts.A new functional appliance was therefore designed to achieve this objective, which drew components from Fränkel's FR I and FR III function regulators. Together with a couple of novel components, it created a hybrid appliance, namely the function regulator for juveniles with a bilateral cleft and a prominent premaxilla: the FR-BCPPm.The patient was treated with this appliance and a nocturnal headgear at 7-13 years, together with a concomitant quad helix appliance followed by a transpalatal arch and bilateral bone grafts. He was then treated non-extraction up to the age of 17 years with preadjusted fixed appliances to correct his residual, crowded Class II malocclusion.The marked improvement in his occlusion, dentofacial appearance and his perioral function after a decade of treatment was then followed up over 20 years, during which time mild relapse of the incisor overjet and moderate recurrence of the lower anterior misalignment was noted two years after treatment.While no further relapse was observed at the four-year post-treatment review, by 20 years after treatment, a little further misalignment of the lower anterior teeth was noted, half of which was deemed to be attributable to age-related maturation.

Presurgical Orthopedic Treatment of a 3-Year-Old Child with Unoperated Complete Bilateral Cleft Lip and Palate and Protruding Premaxilla

Unoperated patients with bilateral complete cleft lip and palate (BCCLP), who do not receive orthopedic treatment in infancy and present with significant sagittal excess of the premaxilla, are among the most difficult patients to treat. Delay in primary reconstruction reduces the elastic characteristics of the tissues. The resulting rigidity of bony structures accompanied by the wide alveolar and palatal clefts associated with sagittal excess of the premaxilla pose a great challenge for both surgeon and orthodontist. There is no unique protocol for treatment of these conditions. This paper describes the use of orthopedic treatment in an unoperated 3-year-old male child with BCCLP and a protrusive premaxilla whose appearance and function were both severely affected. A modified Meazzini technique, as described in operated BCCLP patients with a downward-displaced premaxilla, was used. The device itself consists of the 2 independent components mutually connected by a 17 × 25 steel arch. The first is an active fan-type expander. The second consists of an acrylic cap covering the premaxilla and 3 brackets used for the steel arch application. They are connected by a rectangular steel 17 × 25 archwire. Reduction of the premaxillary sagittal excess of is carried out with an elastic chain. The use of this orthopedic appliance is a reliable and valuable presurgical treatment in the therapy of children with BCCLP and protrusive premaxilla whose orthopedic and surgical treatment have been delayed.

Bilateral cleft lip repair with simultaneous premaxillary setback and primary limited rhinoplasty

Background

Functional closure of the orbicularis oris muscle and esthetic reconstruction of nasolabial components are impossible in patients with severely deformed premaxilla. Here, we review a surgical strategy for patients with unremedied premaxilla retrospectively.

Results

Vomerine ostectomy and premaxillary setback with nasolabial repair were performed in 12 patients with bilateral cleft lip and palate. The mean age of patients was 21.7 months. The extent of ostectomy varied between 3 and 11 mm. There were no serious complications from defective perfusion to the premaxilla or the philtral flap. The follow-up period ranged from 2 to 25 months. Proper positioning of the premaxilla and satisfactory nasolabial esthetics were achieved in all patients.

Conclusions

We performed nasolabial repair after premaxillary setback without jeopardizing the premaxillary segment or the philtral flap. Our surgical strategy could be recommended in poor socio-economic circumstances due to the cost effectiveness of limiting the number of surgeries.
