A Clinical Report Utilizing the VITOM 3D® Microvideoscope for Cleft Palate Repair.

Cleft palate surgery has traditionally presented numerous problems for cleft surgeons including ergonomics, limited visual fields restricting the opportunity for demonstration and teaching. Additionally, the move toward online teaching means the ability to record or livestream video is paramount. The following report of eight cleft palate repairs highlights the novel use of the Vitom 3D® microvideoscope as an innovative technique for cleft palate repair with our early experience demonstrating significant ergonomic and teaching benefits.

Dental arch relationship outcomes in children with complete unilateral cleft lip and palate treated at Princess Margaret Hospital for Children, Perth, Western Australia.

OBJECTIVES: To (1) audit dental arch relationships of all children born between 1982 and 1999 with complete unilateral cleft lip and palate (UCLP) treated at the Cleft Lip and Palate Unit, Princess Margaret Hospital for Children (PMH), Perth, Western Australia, (2) assess the distribution of GOSLON ratings from dental casts taken at 9 years, (3) compare the 9-year GOSLON ratings for "High" and "Low" caseload surgeons, and (4) compare the 9-year PMH GOSLON ratings with published ratings from other units. DESIGN: Retrospective audit of dental casts and medical charts. PATIENTS: Dental casts were retrieved for 71 children (47 boys and 24 girls) at 9 years of age. MAIN OUTCOME MEASURES: GOSLON ratings. RESULTS: Sixty-eight percent of patients had an excellent to satisfactory dental arch relationship (GOSLON Yardstick ratings 1 to 3) at 9 years with a mean rating of 2.85. High caseload surgeons achieved statistically better mean GOSLON ratings than low caseload surgeons (2.72 and 3.33, respectively). CONCLUSIONS: PMH Cleft Unit's dental arch relationship outcomes are comparable to published series of units using similar treatment protocols. High caseload surgeons achieved better dental arch relationships than low caseload surgeons.

A Review of 30 Years of Alveolar Bone Grafting in the Mixed Dentition Using a Standardized Protocol in Western Australia.

BACKGROUND: Outcomes for a continuously applied alveolar bone grafting protocol, established in 1982, are reported and compared to previously published outcomes from the authors' unit and elsewhere. METHODS: A descriptive, retrospective cohort study of alveolar bone grafting outcomes at a tertiary referral cleft center was performed. Records of all alveolar bone grafts between 2002 and 2014 were reviewed (224 grafts). Three-year postoperative periapical radiographs were evaluated using the Bergland, Kindelan, and standardized way to assess graft scores by an external rater. Incomplete records, a syndromic diagnosis, or primary surgery performed elsewhere resulted in 123 grafts being excluded, leaving 101 grafts for assessment. The distribution of scores was compared to the authors' previous studies and international reports. The authors also tested for any impact on the outcome based on cleft type, laterality, timing for incisor or canine eruption, and surgeon experience. RESULTS: A total of 95.6 percent of applicable grafts (66 of 69) were considered "successful" by Bergland scores and 96 percent by Kindelan scores. Eighty-nine percent of grafts were "very good" based on standardized way to assess graft score. No significant differences were detected in outcomes based on timing, cleft type, or laterality. Surgeon experience had a significant impact (p < 0.05) on outcome for Bergland and Kindelan scores. Distribution of Bergland scores did not differ from the authors' earlier studies demonstrating consistent outcomes for over 30 years. CONCLUSIONS: The Western Australian alveolar bone grafting protocol has consistently achieved a very high success rate (96 percent) for over 30 years despite multiple staff changes. These results compared well with best-reported outcomes from worldwide cleft centers. Surgeon training and experience were significant in achieving these outcomes. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Mandibular distraction osteogenesis and maxillary osteotomy in a class II division 1 patient with chronic juvenile arthritis.

A patient with juvenile chronic arthritis presented with a malocclusion characterized by mandibular hypoplasia, symphysial deficiency, and an increased mandibular occlusal plane angle. Correction of the mandibular defect required both the horizontal advancement of the mandible and a counterclockwise rotation of the proximal segment to reduce the mandibular occlusal plane angle. This was achieved by a combination of distraction osteogenesis to horizontally advance the mandible (14 mm), followed by manipulation of the postdistraction regenerate to reduce the mandibular occlusal plane and increase the symphysial projection. The counterclockwise rotation of the mandibular body resulted in the creation of a posterior open bite. After a three-month period to allow consolidation of the mandibular distraction osteogenesis, secondary maxillary surgery at the Le Fort 1 level was performed to reestablish maxillary occlusal contact at the new mandibular occlusal plane. A genioplasty was also performed to improve chin projection.
