Abstract
Microdissection technique under phonomicrosurgery with direct laryngoscopy was performed for 10 cases with shallow lesions resulting form early glottic cancer (8 with T1a and 2 with T1b). Type I cordectomies were performed for 9 cases and type II for 1 case.
Therapeutic outcomes showed 100% of local control rate during the follow-up periods from 6 months to 4 years. One case presented local recurrence which became well controlled by an additional microdissection procedure. Vocal outcomes indicated good preservation of vocal function in terms of maximum phonation time (MPT), mean flow rate (MFR), and acoustic parameters in most cases.
Microdissection technique has proved to be useful for definite local control of shallow lesions of early glottic cancer as well as for preservation of vocal functions postoperatively.
