Therefore, head and neck surgeons are required to make every effort to give them saving treatment in order to improve their quality of life. Prolong the patient's life.

Detailed Description: medical records and extracted information including age, gender, initial treatment modality of glottis cancer, recurrence time, recurrence site, histopathology, tumor grade according to World Health Organization (WHO) grade and tumor stage. Stages were defined according to the American Joint Committee on Cancer (AJCC) staging system.
