Significance of prophylactic paratracheal lymphnode dissection in a case of retrosternal goitre: a case report.
An elective or a prophylactic lymph node dissection is the removal of the lymph nodes that are normal on physical examination and on radiographic imaging. This type of dissection is not based on the visible disease in the targeted nodal basins, but on the potential of a radiographically occult tumour which can exist. The pathologic results of an elective lymph node dissection may help in predic...
متن کاملUpper mediastinal and paratracheal node dissection in total (pharyngo) laryngectomy, it is really indicated?
Introduction: Advanced laryngeal and hypopharyngeal cancers are aggressive tumors with a poor prognosis. Multiple lymph node metastases often occur in the neck as well as in the upper mediastinum and thus upper mediastinal dissection is crucial to improving the cure rate. However, excessive mediastinal dissection can increase postoperative morbidity and mortality making it important to employ t...
متن کاملElective paratracheal neck dissection for lateral metastases from papillary carcinoma of the thyroid: is it indicated?

متن کاملParatracheal lymph node dissection in cancer of the larynx, hypopharynx, and cervical esophagus: the need for guidelines.
In laryngeal, hypopharyngeal, and cervical esophageal carcinomas, the paratracheal lymph nodes (PTLN) may be at risk for lymph node metastasis. The presence of PTLN metastasis is an important prognostic factor for the development of mediastinal and distant metastases, stomal recurrence, and disease-free and overall survival. Studies on PTLN metastasis are scarce. In most studies, PTLN dissectio...
