  • Title: Quantitative and qualitative analysis of tracheoesophageal voice after pectoralis major flap reconstruction of the neopharynx.
    Author: Deschler DG, Doherty ET, Reed CG, Singer MI.
    Journal: Otolaryngol Head Neck Surg; 1998 Jun; 118(6):771-6. PubMed ID: 9627235.
    Abstract:
    Although tracheoesophageal voice restoration is accepted after reconstruction of the neopharynx with the pectoralis major myocutaneous flap, the character of such voice is not well described. Six patients reconstructed with the pectoralis major flap after laryngopharyngectomy underwent successful voice restoration with the Blom-Singer prosthesis. Voice was evaluated by a standardized protocol and compared with voices of control subjects treated with total laryngectomy and similar voice restoration. The patients with pectoralis major flaps produced similar intensity levels for soft voice (53.7 dB vs. 55.6 dB) and loud voice (61.3 dB vs. 65.3 dB) when compared with controls (p > 0.05). No significant differences (p > 0.05) were noted for fundamental frequency (F0) between patients with pectoralis major flaps and controls for soft (62.3 Hz vs. 85.4 Hz) and loud (109.8 Hz vs. 133.8 Hz) voice. Jitter was also comparable. Trained and naive listeners completed qualitative analyses for 10 parameters and judged that control patients had significantly better voice for most parameters. This finding demonstrates that dependable voice is attainable after pectoralis major flap reconstruction of the neopharynx. Although this voice does not differ significantly from voice after standard laryngectomy for acoustic parameters, perceptual analysis does reveal significant differences.
