"Saber-sheath" trachea is a deformity of lower cervical or intrathoracic trachea. The configuration of the deformity is marked coronal narrowing associated with sagittal widening. This deformity is associated with chronic obstructive pulmonary disease. We report a case of patient with saber-sheath who underwent total laryngectomy. Although the patient had no tracheal collapse after the total laryngectomy, crusted discharge was increased. Diagnosis of the saber-sheath trachea, possible causes, and clinical implications are discussed.

Laryngeal cancer is the commonest of all head and neck malignancies and, in Korea, constitutes approximately 2.3% of all malignancies among males. Survival rate is rather higher than any other head and neck malignancies. Treatment results of 121 laryngeal cancer patients were analyzed. 1. Glottic region 44%, supraglottic 41%, subglottic 8%, transglottic 7%. 2. Rate of cervical metastasis according to T stage was 19% in T2 stage, 47% in T3 stage, 69% in T4 stage. 3. Overall 3-year NED survival rate was 65% and showed stage I 93%, stage II 76%, stage III 63%, stage IV 53%. 4. Glottic cancer showed much better prognosis(3-year NED 82%) than supraglottic cancer(3-year NED 58 %). 5. According to treatment modality, complication rates in surgery with postoperative radiation was higher than in surgery along and disproportionally higher in salvage surgery after failed curative radiation.
