Lateral Cephalograms

Objective: This study evaluates skeletal and dental outcomes of LeFort I advancement surgery in patients with cleft lip and palate (CLP) with varying degrees of maxillary skeletal hypoplasia. Design: Retrospective study. Method: Lateral cephalograms were digitized at preoperative (T1), immediately postoperative (T2), and 1-year follow-up (T3) and compared to untreated unaffected controls. Based on the severity of cleft maxillary hypoplasia, the sample was divided into 3 groups using Wits analysis: mild: ≤0 to ≥−5 mm; moderate: <−5 to >−10 mm; and severe: ≤−10 mm. Participants: Fifty-one patients with nonsyndromic CLP with hypoplastic maxilla who met inclusion criteria. Intervention: LeFort I advancement. Main Outcome Measure: Skeletal and dental stability post-LeFort I surgery at a 1-year follow-up. Results: At T2, LeFort I surgery produced an average correction of maxillary hypoplasia by 6.4 ± 0.6, 8.1 ± 0.4, and 10.7 ± 0.8 mm in the mild, moderate, and severe groups, respectively. There was a mean relapse of 1 to 1.5 mm observed in all groups. At T3, no statistically significant differences were observed between the surgical groups and controls at angle Sella, Nasion, A point (SNA), A point, Nasion, B point (ANB), and overjet outcome measures. Conclusions: LeFort I advancement produces a stable correction in mild, moderate, and severe skeletal maxillary hypoplasia. Overcorrection is recommended in all patients with CLP to compensate for the expected postsurgical skeletal relapse.

Detailed Evaluation

AbstractCleft lip and palate patients are born with a challenging deformity that requires multiple surgical interventions in order to reach functional and esthetic harmony. Mid face deficiency in cleft patients is a challenging clinical problem very often encountered in the management of this congenital defect. Cleft maxillary hypoplasia can be attributed to the inherited traits, acquired traits and Induced traits. CLP patients usually present with symptoms varying from malocclusion, retrusion of midface, and a narrow hard palate. A detailed evaluation and individualized treatment planning is of utmost importance in dealing with these patients. Treatment involves the contribution from both the orthodontist and the craniofacial team. The goals for the treatment for cleft maxillary hypoplasia are improvement of aesthetic deficits as well as correction of malocclusion.

Objective: This study aimed to evaluate the Le Fort I osteotomy line and pterygomaxillary junction via cone-beam computed tomography in individuals with cleft lip and palate (CLP). Design: Retrospective study. Patients and Methods: The study included individuals older than 16 years with CLP, who were scheduled for repositioning of the maxilla by Le Fort I osteotomy, and those with class III malocclusion with maxillary hypoplasia, who were scheduled for Le Fort I osteotomy. The measurements made in the area of the cleft of individuals with CLP were compared with both the side with no cleft and those with class III malocclusion with maxillary hypoplasia. A total of 11 measurements were made on the axial section parallel to the Frankfurt Horizontal plane, corresponding to the lower 1/5 of the distance between the infraorbital foramen and the anterior nasal spine. Results: There were significant differences both in the comparisons made between the individuals with CLP and those without CLP in terms of the canal-anterior alveolar crest (G) and sinus-anterior alveolar crest (L) measurements ( P < .05). The mean measurement values showed that the measurement results were higher in individuals with CLP in general. Conclusion: In conclusion, we believe that there might be difficulties both in osteotomy and down fracture stages during Le Fort I osteotomies performed in individuals with CLP.

Maxillary Growth

Background: The goal of palatoplasty is to achieve normal maxillofacial growth, normal speech, and prevent hearing loss. Disturbance of maxillary growth may occur in cleft lip palate patients after palatoplasty. To determine how many patients later developed a disrupted maxillary growth following operations, a retrospective study was designed to evaluate patients with complete unilateral cleft lip and palate who have undergone two-flap palatoplasty.Methods:A retrospective analytic study evaluated the maxillary growth of 15 consecutive unilateral cleft lip and palate patient aged around 8-year-old treated in the Division of Plastic Surgery Cipto Mangunkusumo Hospital, Jakarta. Cephalogram and dental study models were used to assess growth. Cleft lip and palate repair were performed to all patients without alveolar bone graft or any orthodontic treatment. Result: The cephalogram shows that 53,3% of the patients developed maxillary hypoplasia post palatoplasty. Mean value of the Goslon Yardstick was 3,53 (intermediate category by Goslon criteria).No patient fell into the Goslon 1 or 5 categories. Discussion: Disturbed maxillary growth is postulated to be caused by the manipulation and suturing of the maxillary vomer, and scarring of the dentoalveoli post-surgery. Another contributing factor is the intrinsic tissue deficiency. Conclusion: Maxillary hypoplasia is a possible complication following two !ap palatopasty, affecting either anteroposterior, transversal and vertical maxillary growth. This finding needs to be proven especially after the process of growth ceased. It is highly probable that maxillary disruption is higher when the two flap palatoplasty technique leaves lateral areas of denuded bone on the maxillary tuberosity.

Distraction osteogenesis is one of the latest treatment modalities in correcting skeletal discrepancies in the craniofacial region. Maxillary retrusion is a common problem when deformity of the face is concerned, especially in cleft lip and palate patients. Distraction osteogenesis utilizing internal or external has an enormous role in future as an alternative method of skeletal correction in patients with severe maxillary hypoplasia. In addition, periodontal rehabilitation in these patients is of utmost importance especially at the end of treatment. This case report presents one such case of severe maxillary retrusion treated successfully by distraction osteogenesis. JMS 2012;15(1):78-81.
