Abstract
This study aimed to asess the incidence of thyroid gland involvement, factors favoring TGI, indications of hemithyroidectomy, and postoperative complications. It is a prospective analytical study that was performed at the otorhinolaryngology Head and Neck surgery departement, Kasr El Aini Hospital, Cairo University during the period from October 2012 to August 2014. It included 40 patients who were diagnosed T 3 or T 4 laryngeal carcinoma and candidate for total laryngectomy with at least hemithyroidectomy. Statistical analysis was carried out to determine the incidence of thyroid gland invasion clinically, radiologically and histopathologically in laryngeal carcinoma and to correlate it with site and stage of the primary tumor vocal cord fixation, subglottic extension, and prior radiation. Our study included 40 patients; 37 were males (92.5%). The mean age was 61.1 years. We found 4 cases (10%) had thyroid gland invasion by laryngeal carcinoma all were males (100%), two cases (5%) had colloidal nodules and one case (2.5%) had follicular adenoma
