Vidian nerve is created from the connection of the greater petrosal nerve and the deep petrosal nerve (Giraddi et al., 2010). These two nerves transmit parasympathetic and sympathetic fibers respectively. Vidian nerve tumour is one of the rarest known tumours (Hong et al., 2014). Genetic changes effectively play a role in the development of nerve sheath tumors. Of course, due to the rarity of this type of tumor, there is not much information about its causes and risk factors (Yamasaki et al., 2015). The incidence rate of malignant peripheral nerve sheath tumors is about 0.001 % (Fortes et al., 2019). Considering the low prevalence of this tumor and the type of treatment performed on this patient, the investigation of the case presented in this study can lead to a better understanding and more correct treatment. This case report has been proposed due to the very low prevalence of neurofibroma of the Vidian nerve in the world. Vidian nerve supplies sympathetic and parasympathetic fibers to the lacrimal glands and nasopalatine mucosa. In many cases, involvement of the Vidian nerve by neurofibroma can be misleading for doctors. Due to the very low prevalence of neurofibroma of the Vidin nerve, the possibility of its being missed and not diagnosed during the examination of patients by doctors is very high. This case report is presented in order to familiarize scientists with this lesion due to its very low prevalence. This therapeutic approach that was used in this case requires longer follow-up periods, but it can prevent possible complications after surgery. |
