Objectives/hypothesis: To evaluate the outcomes of transoral laser microsurgery (TLM) for T1 glottic carcinoma using longitudinal voice analysis., Study Design: Retrospective analysis of medical records., Methods: We conducted a retrospective review of 57 patients (50 T1a, seven T1b) who underwent TLM for T1 glottic carcinoma, and longitudinal voice analysis was performed before surgery, during the early postoperative period (within 3 months), and during the late postoperative period (more than 6 months). Acoustic, perceptual (Grade, Roughness, Breathiness, Asthenia, Strain scale), and subjective voice analysis using the Voice Handicap Index (VHI) was conducted., Results: Voice quality deteriorated in the early postoperative period in terms of several parameters. However, no significant differences in voice quality were observed in the late postoperative period, whereas Grade (from 1.85 ± 0.83 to 1.50 ± 0.90) and Roughness (from 1.74 ± 0.73 to 1.48 ± 0.87) had improved significantly. Patients who underwent lesser-extent cordectomy (type I, II) showed improvement in VHI-Physical (from 12.93 ± 11.10 to 6.07 ± 8.69) and Grade (from 1.60 ± 0.68 to 0.98 ± 0.83), whereas improvement was not identified in those who underwent larger-extent cordectomy (type III, IV, V). Improvement in Grade (from 1.70 ± 0.80 to 1.23 ± 0.91) and Roughness (from 1.77 ± 0.73 to 1.25 ± 0.76) was identified in patients who had unilateral tumor without involvement of anterior commissure. However, those with involvement of the anterior commissure or bilateral vocal cord showed a tendency toward deterioration in voice quality., Conclusions: Voice quality of patients following TLM for T1 glottic carcinoma may improve significantly over time in cases with lesser-extent types of cordectomy or unilateral tumor without involvement of the anterior commissure., Level of Evidence: 4 Laryngoscope, 126:2051-2056, 2016., (© 2015 The American Laryngological, Rhinological and Otological Society, Inc.)

Objectives/hypothesis: A study was undertaken to determine the oncologic outcomes in a consecutive series of early glottic carcinomas treated with transoral CO₂ laser microsurgery (TLM) as a one-stage single-modality therapy, without any postoperative radiation therapy or retreatment with laser. We further evaluated correlations between the oncologic outcomes and clinicopathologic factors including tumor location and surgical margin., Study Design: Retrospective analysis of medical records., Methods: The medical records of 118 consecutive patients with early stage (T1, T2) glottic carcinoma who underwent TLM by a single surgeon as an initial treatment from 1997 to 2011 were retrospectively reviewed. The oncologic outcomes were evaluated, and correlations to clinicopathologic factors were analyzed., Results: The 5-year disease-free survival, ultimate local control with laser alone, disease-specific survival, overall survival, and organ preservation rates were 87.9%, 94.2%, 99.0%, 92.2%, and 96.2%, respectively. Neither the reported surgical margin nor the extension of tumor to the anterior commissure, arytenoid, subglottis, and ventricle showed any significant impact on local control or survival., Conclusions: Transoral CO₂ laser microsurgery as one-stage single-modality therapy resulted in a high rate of local control and a high survival rate in selected cases of early glottic carcinoma, regardless of the location of tumor and histopathology report on the surgical margin., (Copyright © 2013 The American Laryngological, Rhinological and Otological Society, Inc.)

Objectives: We evaluated the oncological and functional outcomes of salvage transoral laser supraglottic laryngectomy after radiation failure. In addition, we demonstrated the usefulness of laser surgery in patients with recurrent supraglottic cancer., Methods: Between December 1999 and May 2011,7 patients (6 men and 1 woman) underwent transoral laser supraglottic laryngectomy after radiation failure. We conducted 4 different types of endoscopic supraglottic laryngectomy. In the cases with lymph node metastasis, we performed neck dissection at the time of laser surgery., Results: All patients had recurrent squamous cell carcinoma confirmed on the surgical specimen. Two patients were classified as having T1 disease, 2 as having T2 disease, and 3 as having T3 disease with preepiglottic space involvement. The 2- and 5-year overall survival rates were 85.7% and 68.6%, respectively. There was a recurrence at 8 months of followup after laser surgery in 1 patient; he underwent successful salvage total laryngectomy. The ultimate local control rate was 100%, and the laryngeal preservation rate was 85.7%. The hospitalization times ranged from 2 to 32 days (mean, 15.6 days). The mean decannulation time was 10.7 days (range, 5 to 30 days). All patients started oral feeding within 1 to 3 days after surgery., Conclusions: Salvage transoral laser supraglottic laryngectomy following radiation failure seems a feasible and oncologically safe procedure in recurrent supraglottic cancers ranging from T1 to selected T3 with minimal preepiglottic space involvement. It can be an option for minimally invasive organ preservation surgery with lesser morbidity for recurrent supraglottic cancer.

Objectives: Transoral laser microsurgery (TLM) is an accepted alternative to open partial laryngectomy for selected glottic cancers, but its role in salvage of radiation failure is debated., Methods: The records of 18 patients treated by TLM for rT1 and rT2 glottic cancer after curative radiation therapy from 2002 to 2007 were retrospectively analyzed., Results: Of the 18 patients, 10 (56%) remained free of disease after the first TLM. The 5-year local control and laryngeal preservation rates showed better outcomes in rpT1 tumors than in rpT2 tumors (87.5% versus 16.6%, p = 0.02; and 87.5% versus 33.3%, p = 0.03, respectively). However, the 5-year overall survival and disease-specific survival rates showed no significant difference between rpT1 and rpT2 tumors., Conclusions: TLM can be a relatively safe and effective salvage option for rT1 glottic cancer. However, because of its high local recurrence rate, TLM may not be generally recommended for rT2 glottic cancer.
