[The analysis of the curative effect of low-temperature plasma cauterization on the treatment of 146 cases of congenital pyriform sinus fistula].

To investigate the therapeutic effect of low-temperature plasma cauterization on the treatment of congenital pyriform sinus fistula(CPSF).All the 146 patients with CPSF received imaging examination, and the low-temperature plasma cauterization under laryngoscope was performed in the stage of inflammation control.After 6-59 months of follow-up, all patients did not have pharynx fistula, and no massive hemorrhage occurred during and after operation. Nine cases of hoarseness after operation 2 d-1 months to restore normal. Thirty cases were suspected of recurrence, of which 8 cases were cured after incision and drainage, and 4 cases were cured after two cauterization.Low-temperature plasma cauterization is the preferred treatment for the microinvasive, simple, beautiful and repeatable operation of PSF, which can be sugessted as the first-line choice for the treatment of sinus and fistula.
