Knott PD, Milstein CF, Hicks DM, Abelson TI, Byrd MC, Strome M. Vocal Outcomes After Laser Resection of Early-Stage Glottic Cancer With Adjuvant Cryotherapy. Arch Otolaryngol Head Neck Surg. 2006;132(11):1226–1230. doi:10.1001/archotol.132.11.1226
To evaluate the vocal outcomes of patients with early-stage glottic carcinoma undergoing laser resection with adjuvant cryoablative therapy.
Tertiary care center.
Twenty patients with early-stage glottic carcinoma.
Treatment of early-stage glottic carcinoma with endoscopic carbon dioxide laser resection in conjunction with cryoablation.
Main Outcome Measures
Disease-free survival and subjective and objective measures of posttreatment voice quality, based on serial videolaryngostroboscopy.
There was 1 local treatment failure, with an overall mean disease-free follow-up of 32.6 months (range, 3-93 months). Carbon dioxide laser resection and cryoablative therapy were associated with a significant improvement in subjective voice quality (P<.001). Long-term dysphonia was uniformly improved vis-à-vis the pretreatment condition, even among patients with the most advanced disease undergoing the widest resections. Posttreatment web formation was not noted among 4 patients with anterior commissure involvement.
Endoscopic laser laryngeal surgery performed in conjunction with cryotherapy for early-stage glottic carcinoma yielded excellent primary site control, while improving subjective and objective measures of voice quality. Combined laser surgery and cryotherapy is a possible alternative to radiotherapy for selected patients with early-stage glottic carcinoma who desire curative therapy, while optimizing vocal outcomes.
