Schwannomas are relatively slow growing benign tumors of the nerve sheath with a well developed capsule. They can reach a considerable size. Typically, symptoms of schwannomas are based on the affected nerve. We present four cases of this tumor that occurred in the head and neck. The differential diagnosis of small painless nodules in head and neck must include schwannomas as it is likely that nerve sheath neoplasms are more common than previously reported. However, due to benign nature and low recurrence prognosis is excellent.
It is possible to prepare platelet-rich plasma gel without using thrombin clot accelerator. PRP, as prepared and applied to surgical sites in this study, was not observed to significantly enhance bone regeneration. All surgical sites, both in the PRP and control group, showed significant healing changes over 6 months.
Performing exodontia in patients with the precancerous condition of oral submucous fibrosis is difficult but frequently necessary. There is mucositis and trismus, faulty wound healing and predisposition to infection. Exodontia and dentoalveolar surgery in these patients may result in distressing sequelae and diagnosis of any subsequent complications like space infection is difficult. Hence, these patients must be treated as a special care group and measures adopted to ease distress. Literature has been reviewed with an eye to understand the underlying nature of the disease and factors that contribute to these problems.
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.
