Objective: In this experimental study, we aimed to observe the effect of inter-recurrent free nerve graft transposition performed after iatrogenic transection of the recurrent laryngeal nerve on the improvement of vocal cord function in rabbits. Methods: The study consisted of 2 groups as the experimental, and control groups each containing 8 rabbits. The right recurrent nerve was transected both in the control and experiment groups. Inter-recurrent free nerve graft transposition using sural nerve was performed with end-to-side anastomosis in the experimental group whereas in the control group, nerve reconstruction was not performed. Results: After the 3rd postoperative month, the right vocal cord activity was recorded in the experimental group using videolaryngoscopy (VLS) and intramuscular electromyography (EMG). In contrast to the control group, no vocal cord muscle atrophy was found during light microscopic examination in the rabbits of the experimental group. Discussion: Inter-recurrent free nerve graft transposition is an acceptable method which can be considered in patients with iatrogenic recurrent nerve transection.

INTRODUCTION: Paragangliomas are tumors that arise from extraadrenal chromaffin cells and most of them are asymptomatic presenting with painless mass. Retroperitoneal paragangliomas are mostly benign with good prognosis; however, they can present with abdominal pain, palpable mass, or hypertensive episodes. Surgical resection is still the main treatment and necessary for histological assessment. CASE REPORT: A 41 year old female patient presented with 6 months of loss of appetite, weight loss, weakness and breathlessness on exertion.. The patient's initial blood examination showed marked anemia, reduced leukocyte count with neutropenia and lymphopenia and a marked reduction in the platelet count. The patient was admitted for evaluation of her pancytopenia. Magnetic resonance imaging revealed a 8 x 7 x 8 cm sized mass closed to the pancreatic tail invading splenic hilum. A large mass was identified retroperitoneally, closed to the tail of pancreas with a splenic hilum invasion. Total mass resection and splenectomy was performed. DISCUSSION: Complete surgical excision is the treatment of choice for extra-adrenal paragangliomas as well as for recurrent or metastatic neoplasms. Reactive thrombocytosis is a common cause of thrombocytosis. Splenectomy was found to be one of the main causes of extreme reactive thrombocytosis. Reactive thrombocytosis is a predictable finding after splenectomy and management of the thrombocytosis and prevention of complications should be initiated. (C) 2015 The Authors.
