RESUMEN
During the past few years, researchers and practitioners have developed novel techniques, using ansa cervicalis to innervate muscles of the larynx paralyzed due to surgical procedures carried out in the chest and neck areas. During routine dissection of a middle-age male cadaver, an unusual course of the superior root of the ansa cervicalis was observed. In this case, the superior root of the ansa cervicalis fused with the vagus and ran within the carotid sheath, and then joined the inferior root forming the ansa cervicalis in the anterior wall of the carotid sheath. The study of this case will add to our current knowledge of ansa cervicalis and thus aid prevention of injury to the nerve during various surgical procedures
RESUMEN
The arm of tfif's study was to determine indications of keratoplasty during 7 years /1999-vrv Emam-Rveza and Vali-AvSc teaching hospitals of Birjand University of medical sciences. Medical records of all patients who underwent penetrating keratoplasty [PK] in teaching hospitals of Birjand University of Medical Sciences from 1999 to 2006 were investigated retrospectively. The recorded data covered sex, age, indication, job and place of life of the patient. This data were analyzed regarding statistical significance was determined using X[2] analysis. During a 7-year period, total number of 120 patients were operated. The most common indication for PK was corneal opacity [62%], followed by keratoconus 20% and other 18% [Bolus keratopathy plus corneal dystrophia]. The major job group for keratoplasty was farmer and the keratoplasty in patients that live in village [56%] was more than the city [44%]. Corneal opacity was the leading indication for PK. The major cause of corneal scarring was trauma with Thorn barberry and corneal infection in our study
