BACKGROUND: Thyroidectomy is a very common operation nowadays. The indications for surgery are uncertainty about the nature of a thyroid mass, or treatment of a large Goitre causing compressive symptoms, thyroid cancer, or Thyrotoxicosis refractory to medical management.4 Middle thyroid vein is short & stout and also is a fragile structure unsupported by any artery unlike superior and inferior pedicle. Chevrel et al. 5 report its presence in 29%, while for Shima et al. the frequency is 55.2%. The diameter is 2±0.8mm and length is 46.1±18.6mm AIM OF THE STUDY: 1. To study incidence on presence of middle thyroid vein in patients undergoing total or near total thyroidectomy, in MKCG Medical College and Hospital. 2. To study the dimension and other anatomical variation of Middle thyroid vein in patients undergoing total or near total thyroidectomy. 3. To study any change in dimension of Middle Thyroid Vein depending on histopathologic finding. MATERIAL AND METHODS: Source of Data-The patient admitted to the General Surgery Department of M.K.C.G. Medical College and Hospital, Berhampur and who will undergo Total/Near Total thyroidectomy. Methods • Observation during Total/Near Total Thyroidectomy. • Measurement of Length and external diameter of middle thyroid vein, carried out by placing a stainless-steel spring Divider calliper along each vascular section and comparing the distance with, calibration of a measuring scale. 1. Length: The horizontal distance from its origin at outer capsule of thyroid to its termination. 2. Breadth: A segment of vessel cut, open it lengthwise, measure its circumference, and finally, external diameter calculated from it. • Position of vessel carried out by a Divider calliper & measuring scale, using following reference 1. The vertical distance between the termination of middle thyroid vein and the transverse plane passing the upper margin of hyoid bone The horizontal distance between the sagittal plane passing the termination of Middle thyroid vein and its intersection with the mid-sagittal line. All the reports were collected and analysed using software package for statistical analysis (SSPS 20). STUDY DESIGN Prospective Study RESULTS; Out of 72 cases of various thyroid surgery were taken into study during the period from August 2019 to July 2021 M.K.C.G Medical College and Hospital, Berhampur is a tertiary level hospital catering mostly to the population of South Odisha. MTV was found in 19.44% cases, out of which 16.6% of cases was found in left lobe and rest in the right lobe and more frequently in cases with hyperthyroidism that is around 50% and rest in patients with goiter(30.7%). CONCLUSION; Incidence of middle thyroid vein, together with its identification in particular category of cases may be helpful to prevent risk of intraoperative and postoperative bleeding during surgeries.
