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.
