The Clinical And MRI Research After Supracricoid Partial Laryngectomy

Objective: The aim of this study for the imaging of MRI changes in the neck before and after SCPL, observed anatomical variation of throat and neck after SCPL, and analysis of relevant anatomical parameters and laryngeal function between surgical procedure for the modified method to improve laryngeal function to provide theoretical data.Methods: A retrospective analysis from January 2006 to December 2009 at the First Affiliated Hospital of Guangxi Medical University, Otolaryngology Head and Neck Surgery for SCPL for 38 patients with clinical and MRI data before and after operation, in which postoperative MRI follow-up , and 15 cases of complete clinical data for the study, all patients were male, aged 50-70 years, mean 56.25 years. Observe the recovery of laryngeal function after SCPL and compared MRI parameters of measurements and analysis of parameters with laryngeal function recovery. By SPSS16.0 statistical software for statistical analysis of the above.Results:①α-angle,β-angle, L, E, A, AH, SPH, TPH measurement parameters to reflect the hyoid bone, epiglottis, larynx, arytenoid area, cricoid cartilage, before and after surgery location, thickness spoon area, glottal morphological changes, the long axis of the glottis was usually oblique or asymmetrical vocal cord shortening, thickening and smooth surface curved shape, triangle, spindle, "T"-shaped and irregular.②The results show that the number of parameters such asα-angle, the distance between the two greater cornua of the hyoid bone postoperative change in CHEP, these changes have their swallowing function recovery relations, and theα-angle as the size of its operation by the decision of the preoperative size.③The tracheal tube extubation was 100%, CHEP and CHP surgical extubation time was significantly different, CHP prolonged extubation. Tube decannulation rate was 100%, CHEP and CHP surgical extubation time was significantly different, CHP extubation longer.Conclusion:①The significant parameters:α-angle,β-angle, L, E, A, AH, SPH, TPH can reflect the change of larynx after Postoperative.②swallowing-related parameters:αangle, distance between the two greater cornua of the hyoid bone. Quick recovery of swallowing function afterα-angle> 30°;αangle <10°after surgery and patients with easily lead angle toα<30°. Quick recovery of swallowing function which the distance between the two greater cornua of the hyoid bone reduces than Preoperative.③SCPL patients in this study the recovery of laryngeal function as better as reports of home and abroad.
