    Abstract:
    BACKGROUND: To compare pharyngoesophageal segment (PES) pressure values in total laryngectomy patients with and without pharyngeal neurectomy (PN) in the early postoperative period. METHODS: Forty-five previously untreated laryngeal carcinoma patients were enrolled into this prospective randomized study. Twenty of them underwent total laryngectomy with PN, and 25 underwent total laryngectomy without PN. PES pressures were measured on the tenth postoperative day with a four-channel catheter. RESULTS: Average PES pressures in patients with and without pharyngeal neurectomy were 12.82 +/- 6.11 mmHg and 17.40 +/-.72 mmHg respectively (p <.05). When compared with the critical point of 20 mmHg that is closely related to voice attainment in the group without pharyngeal neurectomy, 10 (40%) patients had pressure levels greater than 20 mmHg and in the other group only 1 (5%) patient had a pressure level greater than 20 mmHg. The difference between the groups with pressure levels greater than 20 mmHg was found to be statistically significant (p <.05). CONCLUSIONS: Pharyngeal neurectomy results in a statistically significant decrease of PES pressures in total laryngectomy patients.
