[Small partial laryngectomy without tracheotomy for T1-2 stage glottic carcinoma]

To investigate the feasibility and clinical characteristics of small partial laryngectomy without tracheotomy for T1-2 stage glottic carcinoma.

Forty-five patients with laryngeal squamaous cell carcinoma in T1-2 stage received small partial laryngectomy without tracheotomy.

All patients were primarily healed and were hospitalized for an average of 11.5 days post-operatively. In all patients, the function of respiration and the reflection of cough were normal, and laryngeal obstruction did not happen. The only postoperative complication was subcutaneous emphysema noted in 29 patients. Among them, subcutaneous emphysema extincted after 4-6 days in 26 patiens, only 3 patiens suffered from delayed healing because the subcutaneous emphysema extincted after 2 weeks. Mild subcutaneous emphysema did not affect the function of respiration and deglutition, healing of wound, and psychology of patients. All patients had been followed-up for 1-13 years. Only 2 patients died of tumor recurrence or metastasis. The function of respiration and deglutition were normal in the living patients, and no implanting metastasis on surface of trachea were found.

The theoretical foundation of small partial laryngectomy without tracheotomy for T1-2 stage glottic carcinoma has been well established. This surgical technique is feasible, safe and effective. It can significantly improve clinical outcome of T1-2 stage glottic carcinoma with minimal invasiveness. Furthermore, it can obviously abate the surgical, physiological and psychological trauma on patients.
