The impact of AC involvement on rates of local recurrence, laryngeal preservation, overall survival, and disease\u2010specific survival was compared in both the groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Out of the 296 cases, 61 cases had AC involvement, while in 235 cases AC was free of disease. Local recurrence rate was significantly higher at 29.51% in the group with AC involvement, while only 18.3% cases had local recurrence in the group without AC involvement with <jats:italic>P<\/jats:italic> value of 0.0001. On T stage\u2010wise analysis, 34.8% cases of T2 lesions with AC involvement developed local recurrence, as compared to only 10.26% cases of T2 without AC involvement with significant <jats:italic>P<\/jats:italic> value of 0.007. Larynx preservation rate was 95.8% versus 93.26% in the AC\u2010involved and AC not\u2010involved cases, respectively, without any statistical significance (<jats:italic>P<\/jats:italic>=0.287).
