Intact to the midline of the neck incision give according to the Cunninghams Manual after reflecting the skin and fascia we noted that the absence of isthmus to thyroid gland 2 out of 10 formalin fixed cadavers. The full outlook awareness of agenesis of the isthmus and its associated thyroid anomalies will significantly contribute to Safety measures to be taken during surgical procedures to avoid surgery related complications and assurance diagnosis and planning. |
