The histological appearance includes solid, myxoid and reticular growth patterns. Vimentin and S-100 protein are very sensitive but non-specific immunohistochemical markers of neoplastic myoepithelium. Conservative surgery is the treatment of choice. A case of myoepithelioma of the minor salivary gland of tongue is described, focusing on clinical behaviour, histopathological and immunohistochemical features.展开更多

Suturing in a deep and narrow operative field poses additional difficulties mainly due to the long microsurgical instruments and the difficulty of manipulating a curved needle. <strong>Objective:</strong> In this technical note, we describe a simple modification of a classical curved suture needle into a “ski”-shaped needle. <strong>Methods:</strong> A classical curved needle is stretched using a needle holder. Only the tip of the needle is left slightly bent, imitating a ski. Once the needle is bent into the ski shape, it can be grasped virtually in any position with the needle holder. <strong>Results: </strong>We have used the ski needle technique suturing in several patients in which the operative field was deep and limited such as dura repair in spinal surgery in obese patients, facial nerve grafting in the internal acoustic meatus and posterior inferior cerebellar artery suturing between the caudal cranial nerves. <strong>Conclusion:</strong> This modification facilitates free positioning of the needle in the needle holder and as a consequence results in easy and faster microsuturing in a deep and narrow operative field. The ski needle technique was felt to be superior to the classical curved needle technique.展开更多
