Use of positioning stents in lingual carcinoma patients subjected to radiotherapy.

To evaluate the short-term efficacy of oral positioning stents in minimizing the adverse oral effects of external beam radiation therapy in patients suffering from lingual carcinoma, 48 subjects were selected for this study. Half of the patients (n = 24) were given positioning stents while the other half (n = 24) formed the control group. Subjects were evaluated for oral radiation toxicity effects using the Radiation Therapy Oncology Group's 045 head and neck cancer adverse events grading tool from the National Cancer Institute's Common Toxicity Criteria for Adverse Events over a period of 60 days. The control group showed a significant increase in palatal mucositis, xerostomia, and salivary changes compared to the study group.

Autologous melanocyte transfer via epidermal grafts for lip vitiligo.

BACKGROUND: Vitiligo of the lips is a common concern of great psychologic consequence. Medical therapies are often ineffective due mainly to the absence of hair follicles. The transfer of melanocytes or melanocyte-bearing skin by a surgical procedure may repigment this condition. Only a few surgical modalities have been successful in this "difficult to treat" site. OBJECTIVE: To assess the effectiveness of autologous melanocyte transfer by epidermal grafts for lip vitiligo and to review the literature on the surgical correction of lip vitiligo. METHODS: Twenty-six vitiligo patients (20 women and six men; age range, 13-43 years; mean, 26.8 years) having 31 affected lips with stable disease were included in the study. The suction blisters were raised using our own modified device on the lateral aspect of the thigh. The roofs of the blisters were transferred to the dermabraded recipient area. The dressing, together with the grafts, was removed on day 8. Patients were given photochemotherapy for 6 weeks. In addition, meta-analysis of the published literature on the surgical management of lip vitiligo was also performed. RESULTS: Complete repigmentation was observed in 27 of the 31 lip areas (87%) in 23 of 25 patients (92%) in whom a follow-up for 6 months or more was available. Complications observed were persistent hyperpigmentation in 12 lips and reactivation of herpes in one patient. Minimal hyperpigmentation was seen in most of the remaining lips. The results of the meta-analysis revealed that the success rate varies from 32.5% to 100% with various surgical procedures. CONCLUSION: Autologous melanocyte transfer is an effective and safe therapeutic option for stable vitiligo of the lips. It is cosmetically more acceptable, as there is no abnormal keratinization, which is a problem associated with dermo-epidermal grafts.
