Peripheral nerve injury may result in injury without gaps or injury with gaps between nerve stumps. In the presence of a nerve defect, the placement of an autologous nerve graft is the current gold standard for nerve restoration. The clinical employment of tubes as an alternative to autogenous nerve grafts is mainly justified by the limited availability of donor tissue for nerve autografts and their related morbidity. The purpose of this review is to present an overview of the literature on the applications of nerve conduits in peripheral nerve repair. Moreover, the different steps that are involved in the design of an ideal nerve conduit for peripheral nerve repair, including the choice of biomaterial, fabrication technique, and the various potential modifications to the common hollow nerve tube, are also discussed.

The facial paralysis patient suffers serious functional, cosmetic, and psychological problems with impaired ability to communicate. Despite the advances of recent years and the number of new techniques proposed in the literature, facial reanimation remains a challenge for the reconstructive surgeon. With the advent of microsurgery, reanimation of the paralyzed face took a major leap forward with the use of cross facial nerve grafts, nerve transfers, and free muscle transplantation. Today, nerve transfers represent the backbone of facial reanimation, especially in cases where reconstruction of the affected facial nerve is not feasible. The suitability of each nerve transfer is related to the type of facial palsy, time elapsed since injury, and the age and general health of the patient. The selected motor nerve must provide strong muscle contraction and allow the patient to control the facial movements. The purpose of this chapter is to present the senior author's (J.K.T.) experience in the selection of motor nerves that can function as possible donor nerves for dynamic facial reanimation. Indications and surgical technique for each procedure is also presented.

IntroductionDe Garengeot first described the presence of the appendix within a femoral hernia in 1731.Case presentationWe report the case of a 66-year-old Caucasian woman who presented with acute appendicitis within an incarcerated femoral hernia. This is the first reported case of de Garengeot's hernia in the Balkan area.ConclusionsAppropriate management without incurring any delay for radiological imaging can be promising for an uneventful postoperative course. The treatment of choice of this disease entity is emergency surgery and consists in simultaneous appendectomy through the hernia incision and primary hernia repair. In patients with large hernia defects or in older people the use of mesh for repairing the hernia defect can be an excellent choice.
