Abstract:
Objective To assess the feasibility and curative effects of laser surgery in treatment of early-stage glottic carcinoma under self-retaining laryngoscope with nasal endoscopic assistance.Methods Thirteen cases of glottic carcinoma(TisN0M0:2 cases;T1aN0M0:7 cases;T1bN0M0:3 cases;T2N0M0:1 case) extirpated with Nd:YAG laser or Diomed laser from June 1999 to March 2003 were retrospectively analyzed.Because of the poor glottic exposure with self-retaining laryngoscope under general anesthesia,various angular nasal endoscopes were used.The tumor was distinctly displayed on monitor screen with nasal endoscopic assistance and were completely removed through vapourization or removed with Nd:YAG laser or Diomed laser.Results The follow-up period was three to five years.Two patients were found to have local recurrence.One patient received treatment with Nd:YAG laser surgery under electronic laryngoscope with local and superfacial anesthesia,and the patient was followed up for three years without showing recurrence.The other patient underwent vertical hemilaryngectomy and was followed up for three and half years without showing recurrence.All 13 cases were followed up for three years,and all of them were alive.Three-year survival rate was 100%(13/13).When they were followed up for five years,one patient lost track(counted as death),therefore the five-year survival rate was 92.3%(12/13).Conclusions With the assistance of various angular nasal endoscope,the glottic tumors can be exposed distinctly under self-retaining laryngoscope and removed completely.Nd:YAG laser or Diomed laser is an effective and safe procedure with minimal invasion for the treatment of early-stage glottic carcinoma.The advantages of this technique include lower complication rate and high rate of preservation of laryngeal functions,avoidance of tracheotomy and the sequela of laryngeal fissure.
