[Removal of laryngeal cancer with thyroid cartilage membrane excision and repair of laryngeal cavity with outside thyroid cartilage membrane flap of healthy side: oncologic and functional outcomes].
OBJECTIVE
To study the efficacy and feasibility of removal of laryngeal cancer with thyroid cartilage membrane excision and repair of laryngeal cavity by the outside thyroid cartilage membrane flap of healthy side.


METHODS
A total of 28 patients were reviewed who underwent the removal of laryngeal cancer with thyroid cartilage membrane excision combined with the repair of laryngeal cavity by the outside thyroid cartilage membrane flap in our hospital between 2005 and 2011. Respiratory function, swallowing function, and voice quality of patients after surgery were evaluated. Survival and recurrence were observed with the follow up of five years.


RESULTS
The decannulation rate was 96.4%. Aspiration rate was 10.7%, but aspiration was completely revolved by swallowing training in the patients. All patients had the voice quality required for communication although they complained of hoarseness after surgery. Tumor recurrence was found in one patient and cervical lymph node metastasis in 2 patients. The three-year and five-year survival rates were 89.3% and 85.7% respectively.


CONCLUSIONS
This surgical procedure was applicable in some of patients with T2 laryngeal cancer, with good laryngeal functions after surgery.
