RESUMO
OBJECTIVES: Mucocele of the minor salivary gland is usually caused when the duct is injured, mucus leaks into the tissue space and the mucous gland are obstructed, which lead to cystic lesion formation and dilatation. Currently, there are multiple therapeutic methods available with various outcomes. This study aims to provide clinical evidence of polidocanol sclerotherapy for the treatment of mucocele of the minor salivary gland. METHODS: In this study, we injected polidocanol into 112 patients who were diagnosed with mucocele of the minor salivary gland and evaluated the treatment efficacy and safety systematically. RESULTS: Of the 122 cases, 102 cases were cured, eight cases showed remarkable remission, and two cases had partial remission. No recurrence was found during follow-up, and none of the cases showed an invalid effect, resulting in a total cure rate of 91.07%. No severe side effects were observed during treatment or the follow-up period. No significant difference in efficacy between different genders was found (P = 0.490). Polidocanol sclerotherapy for mucocele on the lower lip was more effective compared to mucocele on the inferior surface of the lingual apex (P = 0.035). CONCLUSION: Polidocanol sclerotherapy showed satisfying curative effects for mucocele of the minor salivary gland without causing side effects of anesthesia, trauma, or severe pain.

Rib segment, as one of the most widely used autologous boneresources for bone repair, is commonly isolated with an empty left in the defect. Although defective rib repair is thought to be unnecessary traditionally, it's of vital importance actually to promote rib regeneration for patients with better postoperative recovery and higher life quality. Comparative investigations on rabbit rib bone regeneration with and without graft were reported in this article. A segmental defect was performed on the 8th rib of 4-month-old male New Zealand rabbits. The mineralized collagen bone graft (MC) was implanted into the defect and evaluated for up to 12 weeks. The rib bone repair was investigated by using X-ray at 4, 8 and 12 weeks and histological examinations at 12 weeks after surgery, which showed a higher bone remodeling activity in the groups with MC implantation in comparison with blank control group, especially at the early stage of remodeling.

RESUMO
Repairing damage in the craniofacial skeleton is challenging. Craniofacial bones require intramembranous ossification to generate tissue-engineered bone grafts via angiogenesis and osteogenesis. Here, we designed a mineralized collagen delivery system for BMP-2 and vascular endothelial growth factor (VEGF) for implantation into animal models of mandibular defects. BMP-2/VEGF were mixed with mineralized collagen which was implanted into the rabbit mandibular. Animals were divided into (i) controls with no growth factors; (ii) BMP-2 alone; or (iii) BMP-2 and VEGF combined. CT and hisomputed tomography and histological staining were performed to assess bone repair. New bone formation was higher in BMP-2 and BMP-2-VEGF groups in which angiogenesis and osteogenesis were enhanced. This highlights the use of mineralized collagen with BMP-2/VEGF as an effective alternative for bone regeneration.
