During routine dissection of a 75-year-old male cadaver, we observed a communicating branch between the posterior femoral cutaneous nerve and the sciatic nerve. The connection was 11 cm below the infrapiriform foramen and was 3 cm long. Excluding this communicating branch, the origin, course and distribution of the posterior femoral cutaneous nerve showed no variation. The other branches of the sacral plexus were as usual.

Introduction: In this study, we aim to compare the levels of matrix metalloproteinase 9 (MMP9) in the gingival crevicular fluid (GCF), as indicators for healing, in two groups of patients - operated with a classic periodontal surgical technique and the same technique but using a dental microscope. Materials: We included 14 patients with ages between 12 and 26 years, average 14+/-6.2 years. Eight patients were women and six men. All patients presented gingival hypertrophy because of the orthodontic treatment on the mandibular arch. We performed gingivectomy on one-half of the mandibular arch by classic periodontal surgery and on the other half of the mandibular arch by a microscope-assisted gingivectomy. Methods: In the hypertrophied gingiva, the expression of MMP9 was identified using immunohistochemical-staining techniques. For immunological determination of MMP9 in GCF we performed Elisa tests. Results: We found different levels in different moments of the healing process for the two hemiarcades. Conclusions: We consider that faster healing in case of microscope-assisted gingivectomy may be related to the expression of MMP-9 in the GCF.
