A study on the type of lesions achieved by three electrosurgical methods and their way of healing.

The technical progress in the medical sector in the past decades has continuously driven the development of electrosurgical techniques. The controversies surrounding the superiority of a certain technique relative to another - electrocautery, laser and radiofrequency - have determined us to carry out a histopathological design with the aim of comparing the healing sort of the shallow wounds generated by the three types of electrosurgical devices. The experimental study has investigated the healing process inflicted by the electrosurgical devices mentioned beforehand on 12 Wistar albino rats.

Ultrasonographic and histopathological features of cervical lymph node metastases.

Objectives: Different approaches have been made to differentiate benignant from malignant cervical lymphadenopathy using ultrasound examination. Assessment of nodal status is essential in patients with head and neck carcinomas as it predicts prognosis and helps in the selection of treatment options. The present study was designed to evaluate the role of ultrasound in the assessment of malignant cervical lymph nodes using the histological gold standard results.
