Tracheoesophageal voice following tubed free radial forearm flap reconstruction of the neopharynx.
Tracheoesophageal voice restoration after laryngectomy is possible with a variety of neopharyngeal reconstructions. We have used the tubed radial forearm free flap for neopharyngeal reconstruction since 1991. Six patients have undergone voice restoration with the Blom-Singer prosthesis and were available for quantitative and qualitative speech analysis. These patients were compared to five laryngectomy patients with standard pharyngeal closures and similar voice restorations. The free flap patients produced similar loudness levels compared to the standards with soft speech (52.06 dB and 47.19 dB, respectively) and loud speech (62.66 dB and 60.91 dB, respectively). The free flap patients demonstrated adequate intelligibility, with fundamental frequencies comparable to standards (124.82 Hz and 135.66 Hz, respectively), although with increased jitter (5.00% versus 1.96%). No differences were statistically significant, but evaluation by trained and naive listeners demonstrated significant differences in voice quality. This quantitative and qualitative and qualitative analysis of tracheoesophageal speech after radial forearm free flap reconstruction of the neopharynx demonstrates that acceptable voice can be achieved, but with limitations.
