[An observation on long-term results of subtotal laryngectomy with preservation of an arytenoid cartilage].
OBJECTIVE
To discuss the long-term results of the subtotal laryngectomy with preservation of an arytenoids cartilage.


METHODS
The long-term results of the subtotal laryngectomy with preservation of an arytenoids cartilage were analysed in 82 patients with squamous cell carcinoma of larynx (stage III 73 cases, IV 9 cases; supraglottic type 71 cases, glottic 6, transglottic 5).


RESULTS
The functions of speech and deglutition were recovered in 82 patients, and the respirations were normal in 69 of 82 cases (84.2%). Pharyngeal fistula appeared in 2 cases, and the infection of incision wound in 6, but all of them were cured by conservative treatment. All of 82 cases were followed-up for more than 5 years, 5 cases were lost follow-up, so the follow-up rate was 93.3%. 26 patients died of various causes during 5 years after operation. 5 of 26 cases died of local recurrence of laryngeal carcinoma, neck metastasis in 4, others in 4 (cardiac insufficiency, myocardiac infarction, lungs metastasis, rectal carcinoma 1 case, respectively) unknown in 4, lost follow-up in 5.68 patients were followed-up for more than 10 years, 30 cases were dead (26 cases who died of various causes included during 5 years after operation; died of local recurrence in larynx was 1 case, unknown 2, lost follow-up 1, during 5 approximately 10 years after surgery). 5, 10 years survival rates were 68.3% (56/82) and 55.9% (38/68), respectively.


CONCLUSIONS
Subtotal laryngectomy with preservation of an arytenoids cartilage is recommended for T3 and some elective T4 laryngeal carcinoma.
