Noma, also known as cancrum oris, is an infectious disease that results in a loss of orofacial tissue, due to gangrene of soft and bony tissue. It is especially seen in young children in the sub-Saharan region. Among the sequelae of patients who survive noma, trismus is one of the most disabling. ⋯ The mean mouth opening in this group was 10.3mm (95% CI: 7.0; 13.6mm) and the mean period after discharge from hospital was 43 months. Better mouth opening was observed in patients who continued physiotherapy after discharge, were older, and those with a 'soft' (vs. 'hard') inner and outer cheek on palpation. The result of trismus release in noma patients in the long term was extremely poor in this study.

Comparative StudyPrefabricated nerve conduits advance histomorphological and functional outcomes in nerve regeneration of the sciatic nerve of the rat.
Bridging a nerve defect is sometimes necessary to achieve nerve regeneration after injury. Different methods and conduit designs have been considered, but only isograft transplants or prefabricated conduits are available. This study presents a comparison of prefabricated conduits and isograft transplants in rats, with the aim of making suggestions for clinical settings. ⋯ Reconstruction in the isograft group showed a negative impact on the non-operated side. Conduits and isografts did not reach the morphological or functional levels of untreated or sham-operated animals. The results suggest preferential conduits should be used for nerve reconstruction.
