The purpose of this study was to compare the efficiency of using autologous platelet-rich fibrin versus a resorbable collagen membrane in secondary alveolar bone grafting. Patients were randomly allocated to the three treatment groups: Group 1 - twelve children in whom the nasal layers of the alveolar clefts were repaired using autologous platelet-rich fibrin with autogenous chin bone; Group 2 - twelve children in whom the nasal layers of the alveolar clefts were repaired using bovine collagen membrane type I (Colla-D) with autogenous chin bone; and Group 3 - twelve children in whom the bony alveolar clefts were grafted with autogenous chin bone after construction of a watertight nasal floor had been completed. The study population comprised 36 patients with alveolar clefts, ranging in age from seven to 12 years. At the last follow-up period all groups had stable healing conditions and good radiological outcomes in terms of the alveolar bone height bordering the teeth (both mesially and distally) and the incorporation of grafting material with the surrounding bone. The use of either a PRF membrane and a collagen membrane as an interpositional layer between the nasal layer and the autogenous chin bone graft enhanced bone formation and density in alveolar clefts compared with the control group.

The purpose of this study was aimed to compare the efficiency and safety of retromandibular versus modified Risdon approach using periangular incision for open reduction and internal fixation of low subcondylar mandibular fracture. Open reduction and internal fixation with different plating systems were utilized via retromandibular approach (group I) and via modified Risdon approach with periangular incision (group II). Twenty four (n= 24) condylar fractures in 21 adult patients were divided randomly into two equal groups (12 each) according to the cutaneous incision (approach) utilized. The evaluation score for scarring in group I it was excellent in 9 patients, good in 2 patients and acceptable in only one patient (Mean 2.4 ± SD 3.38). While in group II was excellent in 10 patients and good in 2 patients (Mean 2.4 ± SD 3.87) and the p value was 0.591. Symptoms of transient facial nerve weakness were noted in only 3 patients in group I with slight to moderate dysfunction (Mean 2 ± SD 3.21), while only one patient had facial nerve weakness in group II with House - Brackman score of 2 immediate postoperatively and this got resolved in 6 weeks (Mean 2 ± SD 4.04) and the p value was 0.00022. Within the limitations of the study it seems that a modified Risdon approach using periangular incision for reduction and fixation of low subcondylar fracture should be preferred whenever possible because it yields better outcomes.

BACKGROUND: Unicystic ameloblastoma is a distinct clinicopathological entity with its cyst-like radiographic appearance and occurrence in the mandible of young patients. Surgical resection of the mandible leads to jaw deformity and challenging reconstruction burden, especially among young patients. Conservative treatment, however, results in less serious function and esthetic impairment. PURPOSE: We aimed at evaluating dredging method as an alternative conservative surgical approach in young patient with large unicystic ameloblastoma. PATIENTS AND METHODS: Twenty patients (n=20) with histologically-diagnosed unicystic ameloblastoma were recruited for this prospective study. The surgical treatment protocol comprised an initial deflation (marsupialization) step, followed by later enucleation and subsequent repeated separate dredging procedures. RESULTS: The study population comprised 16 males and 4 females. The average age at the time of diagnosis was 18.5 years. At the last follow-up period, achievement of normal mandibular bone contour with no radiographic signs of recurrence was evident. CONCLUSION: The dredging method as a modified surgical technique may represent a reliable approach for management of unicystic ameloblastoma in young patients.
