“…18 In the present series, all 16 patients with cT2 cancer had an impaired vocal cord mobility with a normal arytenoid mobility, and TA muscle infiltration was found in nine of them (56%). As long as the disease is limited to the TA ligament, vocal cord mobility does not change substantially, whereas any invasion of the TA muscle is likely to be associated with a mobility impairment.…”

Background The involvement of the thyroarytenoid (TA) muscle by glottic cancer may be related to an impaired vocal cord mobility, which is classified as cT2 disease. The primary endpoint was to evaluate the prognostic significance of TA muscle involvement in early glottic cancer treated with transoral laser microsurgery (TLM). Methods A review was conducted on a cohort of 209 patients consecutively treated with TLM for early glottic carcinoma. Univariate analysis was used to examine the prognostic meaning of clinical and pathological parameters. Results The statistical analysis showed that TA muscle infiltration correlated significantly with a worse prognosis in terms of recurrence rate and disease‐free survival, and this was confirmed even in the subcohort with pT1a glottic cancer. Conclusions Our preliminary findings suggest that it could be considered as a criterion for upstaging a glottic cancer from pT1 to pT2.

“…The use of SCL in the treatment of tumors causing cord fixation has decreased the number of total laryngectomy and near-total laryngectomy procedures in our practice. Based on the evaluation of 80 laryngectomy specimens, Hirano et al [7] determined that the most common reasons for cord fixation were the extensive invasion of the thyroarytenoid muscle in glottic tumors and deep massive tumor invasion of the Fig. 1 Overall survival rate after supracricoid laryngectomy with cricohyoidopexy Fig.…”

This study assessed the oncological results in patients undergoing supracricoid laryngectomy with cricohyoidopexy. A cohort of 44 patients surgically treated using supracricoid laryngectomy with cricohyoidopexy between June 2001 and December 2009 was retrospectively analyzed. The mean follow-up period was 53.2 (±24.7) months. The Kaplan-Meier method was used to analyze overall survival and disease-specific survival, as well as survival according to T2 and T3 subgroups. Overall survival rates at 3 and 5 years were 90.5 and 84.1%, respectively. The 3- and 5-year disease-specific survival rates were 95.4 and 92.5%, respectively. Overall survival for patients with T2 disease was 87.5% at 3 years and 80.8% at 5 years. For T3, the corresponding rates were 91.8 and 87.0%. Disease-specific survival for patients with T2 disease was 93.3% at 3 years and the same at 5 years; the corresponding rates for T3 were 96.4 and 91.4%. The differences between T2 and T3 patients at 3 and 5 years with respect to overall and disease-specific survival were not statistically significant (P = 0.903 and P = 0.863, respectively). Recurrence was local in one patient (2.2%) and regional in three (6.8%). There were three distant metastases (6.8%) and one second primary carcinoma (2.2%). These findings support the use of supracricoid laryngectomy with cricohyoidopexy as an oncologically safe technique in properly selected patients with laryngeal carcinoma.

“…In fact, on analysis of 23 larynx with serious true vocal cord fixation, Kirchner and Som 8 found that the neoplastic invasion was limited to the paraglottic area and had not invaded the cricoid or thyroid cartilage. On the other hand, Olofsson et al 9 and Hirano et al 10 observed an invasion of the thyroarytenoid muscle in their anatomopathologic studies on all cases of true vocal cord fixation. In these particular clinicopathologic cases, other authors used vertical surgery, resulting in relapse in from 9% to 46% of the patients.…”
