Transnasal Vocal Fold Polypectomy
PENTEX EPM 3500 electronic flexible laryngoscope and PENTEX surgical flexible oval micro cup forceps were used for TVFP. The nasal and pharyngeal mucosa was anesthetized with 1% tetracaine. 1 ml of 1% tetracaine was dripped through the operative channel (OC) of electronic laryngoscope onto the epiglottis and glottic area. The patient was placed in a supine position on a headrest. The electronic laryngoscope was inserted through the contralateral anterior nostril, and the flexible forceps were introduced through the OC. When the operation time was prolonged, 1% tetracaine could be added from the OC and the total amount of tetracaine was controlled within 20mg for adults. The polyps were removed with forceps vertically along the base of the polyps, and the residual tissue was trimmed until the vocal cord was flattened (Figure 2). The revision surgery was performed approximately 2 weeks after the previous operation.
