Evaluation of Alveolar Bone Reconstruction In Clefts With Early Or Late Secondary Bone Grafting: Use Of The 3d Kamperos score.

There is still no consensus on the optimal age for alveolar grafting. In order to decide on the success of this graft, the best known radiographic assessments lacks precision. Kamperos recently proposed a 3D CBCT score that simultaneously assesses alveolar bone height and thickness, as well as the nasal floor level. The aim of this study was to apply this new score and compare it between an early secondary alveolar grafting « ESAG ¼ (4-7 y) and a late secondary alveolar grafting « LSAG ¼ (8-11 y) surgery group. A total of 32 cases of ESAG and 17 of LSAG were analysed. On 3D imaging, the median age of ESAGs was 10 years and 15 years for LSAGs. In the ESAGs, 78% of the permanents canines were not on the arch compared to 18% in the LSAGs. In both groups, the reconstruction of the nasal floor was very adequate but the height and thickness appeared less good in the ESAGs. The final score was higher in LSAG (Chi2, P < 0.005). The analysis of the alveolar bone with the Kamperos score is accurate and relevant but it should preferably be performed in the permanent dentition phase. This is because the area of rhizalysis of the primary teeth and the follicular sac of the erupting permanent teeth influence the presence of effective bone.

Early effect of vomerine flap closure of the hard palate at the time of lip repair on the alveolar gap and other maxillary dimensions.

OBJECTIVE: Comparison of the effects of vomerine flap (VF) closure of the hard palate at the time of lip repair with non-closure of the hard palate in subjects with unilateral cleft lip and palate (UCLP). DESIGN: Retrospective, single-blinded, cohort study. SETTING: Study model sets of 40 consecutive, non-syndromic, infants with complete UCLP operated on between 1988 and 1998. PATIENTS: All subjects were operated on by a single consultant plastic surgeon immediately before and after the unit's change of protocol (1993), when VF closure of the hard palate was incorporated at the time of lip repair. Subjects were divided into two groups: VF ( n = 18) and non-VF (n = 22), which acted as a control group. Each subject had maxillary impressions taken before lip repair at 3 months (VF mean age = 11.7 weeks; non-VF mean age = 13.4 weeks) and before palate repair at 6 months (VF mean age = 22.8 weeks; non-VF mean age = 24.0 weeks). MAIN OUTCOME MEASURES: Seven predetermined landmarks and four maxillary dimensions were computed following single-blinded analysis using a reflex microscope. RESULTS: Repeatability tests showed good measurement precision. The operator measurement errors were 0.00018 mm in a horizontal plane (X and Y) and 0.00028 in the vertical plane (Z). The VF group showed significant changes in the alveolar cleft width. There were no statistically significant changes in any arch-form variable between the VF and non-VF groups. CONCLUSION: The decrease of alveolar arch gap width at palate repair (6 months) in the VF group was significantly more than the decrease observed in the non-VF group, and there was no significant decrease in the, anterior and posterior arch width or anteroposterior length of the hard palate in the VF group compared with the non-VF group.

Early surgical excision of giant congenital hemangiomas of the scalp in newborns: clinical indications and reconstructive aspects.

BACKGROUND: Infantile hemangioma is the most common vascular tumor in newborns, with an incidence from 12 to 23% among preterm infants with low weight at birth and a female to male ratio of 3:1. The head and neck is the most frequently affected area (60%), and the scalp is a typical site for such large lesions. OBJECTIVE: We describe some clinical and medical aspects in comparison with the surgical approach to giant infantile hemangioma of the scalp. METHODS: The indications to treatment are discussed. An outcome basis evaluation, by reviewing some clinical cases, is provided to help readers better understand when and how to undergo surgery safely. CONCLUSION: Early excision of huge infantile hemangioma of the scalp is the treatment of choice if feasible within 5 months of age.

Surgical management of macroglossia: discussion of 7 cases.

OBJECTIVE: We present an overview of international literature concerning macroglossia-related etiology, clinical and instrumental diagnoses, surgical treatments, complications, and recurrences. Moreover, we present a series of cases of patients affected by macroglossia who have been treated surgically at the Department of Maxillofacial Surgery of the University of Rome "La Sapienza". METHODS: Between 1990 and 1999, only after attempts to solve this pathologic condition with medical and orthodontic treatment, we treated surgically a total of 7 patients (4 male and 3 female). The surgical techniques used were Köle glossectomy and Dingman and Grabb glossectomy. We analyzed the clinical and instrumental study and the surgical treatment, including possible complications and recurrences. RESULTS: After follow-up of a period from 2 to 9 years, macroglossia recurrences were absent, showing that the Köle and the Dingman and Grabb glossectomies are viable surgical options for treatment of macroglossia. CONCLUSION: The best therapy for each case macroglossia must be carefully evaluated, with the right medical therapy and orthodontic therapy attempted first and surgical treatment performed only when the first and second therapy fail. Moreover, surgical techniques must be chosen in accordance with the functional results that one wants to achieve and must be the most conservative technique to preserve the vascular-nerve bundle.
