Objective Hairline vitiligo is a special area. Hairy areas within the hairline often require repigmentation and regrowing hair shafts. The face and forehead outside the hairline do not require regrowing hair shafts, only repigmentation. To tackle this issue, we modified the conventional mini-punch grafting with a combined application of mini-punch grafting and follicular hair transplant. Methods Five patients with localized hairline stable vitiligo aged 26–32 years old had a history of nonsurgical treatments for at least 3 months and without progress. The grafts were transversely sectioned. The intact half follicles were preserved below the cross-section. Sectioned grafts were placed into the chambers for transplanting with forceps. Results The treatment using transversely sectioned mini-punch grafting with the patient was performed for all five patients, and the results were satisfactory. In the area of the forehead outside the hairline with the sectioned mini-punch grafting above the cross-section, hair loss and repigmentation were observed. In the area of the hairy areas within the hairline, growing hair shafts and repigmentation were observed, without hair loss. Conclusion Our report can help to manage hairline vitiligo or hairy areas vitiligo. This method can be considered a potential method for the treatment of hairline vitiligo, thus providing a simple solution to complex problems.
The damaged inferior alveolar nerve of rabbit was repaired with autogenous ipsilateral greater auricular nerve grafting primarily and secondarily, and electrophysiological, ultrastructural, microvascular and histochemical investigations were performed in this study. The results indicated that the experimental effects of group 1 out of 3 groups (group 1 with immediate grafting, group 2 with grafting after 4 weeks, and group 3 with grafting after 8 weeks) were the best and those of group 2 were second only to group 1 with no obvious difference between these two groups (P greater than 0.05). However, the results of group 3 were not good enough, and there was significant difference from the other two groups (P less than 0.05). Therefore, we were led to conclude that the injury should be repaired at once or within 4 weeks after inferior alveolar nerve was damaged, or within 2 or 3 months thereafter, to improve the function of the injured nerve as greatly as possible.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
