The long term impact of thyroidectomy in laryngeal cancer surgery

الملخص EN

Dnttebucllon : Direct extension into the thyroid gland may occur in carcinomas of the larynx, trachea, esophagus and pharynx.

The standard surgical treatment of these tumors usually includes partial or total thyroidectomy.

The objective of our research work is to study excised thyroid lobes, trying to explain its possible effect on the tumor prognosis and subsequent late complications.

/ Hautlals A /Htihehs : Retrospective study performed using a twenty serially sectioned whole organ laryngectomy with thyroidectomy specimens.

The specimens were thoroughly sectioned at different levels with particular attention to the thyroid lobes.

The results were compared with the preoperative clinical data and the late postoperative complications.

Tttsulls : Clinical tumor staging records were of advanced type.

Two of the excised thyroid lobes demonstrated an invasion with sequamus cell carcinomas.

In most instances the subglottic space and the laryngeal skeleton were involved by tumor cells.

Seven patients developed stoma recurrence and three had recurrent pharyngeo-cutaneous fistula.

Conclusion : Thyroidectomy is not a routine part of total laryngectomy and had questionable efficacy to the late patients' outcome and tumor recurrence.

Metastasis to the Subglottic site accused as a poor prognostic sign of laryngeal carcinoma
