Presentación sobre la nueva técnica quirúrgica para la mucosidad. - Actividades de investigación

Kim Hyung-tae, director del Yeson Voice Center, presentó y presentó por primera vez los resultados del tratamiento de la nueva técnica quirúrgica de colgajo mucoso tipo sándwich para el puente mucoso de las cuerdas vocales en el 82º Congreso de la Sociedad Coreana de Otorrinolaringología. Esta nueva técnica quirúrgica fue presentada grandes mejoras para la voz, una enfermedad persistente que hasta ahora no tenía ningún tratamiento especial.

El 82º Congreso de la Sociedad Coreana de Otorrinolaringología se celebró en el Hotel Grand Hilton de Seúl del 25 al 27 de abril.

Document title : New surgical technique for mucosal bridge of vocal fold : sandwich mucosal flap surgery

Presented by: Kim, Hyung-tae

Name of clinic: YesonVoiceCenter

Objectives: The mucosal bridge of the vocal fold is a disease resulting from perforation of a mucous membrane due to vocal cyst or sulcus vocalis. Voice improvement after surgical treatment is very difficult. Mucosal bridge does not recover through simple excision, and there are no surgical techniques to treat it. The objective of this document is to evaluate the results and phonetic changes of the new surgical technique of sandwich mucosal flap as a method to preserve the voice.

Method: 6 patients who were diagnosed as mucosal bridge and received sandwich mucosal flap surgery atYesonVoiceCenter from April 2005 to April 2007 were enrolled in this study. The causes and accompanying diseases were epidermoid cyst (3 cases), sulcus vocalis (2 cases), and polypoid vocal folds (1 case). 3 males and 3 females at an average age of 34.8 were subject to this study. The patients were followed for an average period of 12.4 months. All 6 cases were performed under sandwich flap surgery, and PDL surgery was additionally performed in 1 case. At 2 months and 6 months after surgery, voice evaluation was done through laryngeal stroboscopy, and subjective voice satisfaction was measured. Significance was tested with Wilcoxon Signed Ranks Test.

Results: Improvements in subjective evaluation of voice were shown through the Voice Handicap Index which had changed from an average of 20.9 to 16.4. Under arerodynamic studies, subglottic air pressure decreased, but the MPT rather decreased. Under voice assessment evaluation, sPPQ, sAPQ, NHR, an DSH were all significally decreased. In laryngeal stroboscopy, 6 cases showed significant improvements in the mucosal wave. Initial hoarseness was noticed as a complication in all cases, but problems from the falling off of mucosal flap or mucosal suture, or symptoms like coughing, feeling of foreign substance, or expectoration did not occur.

Conclusion: The new surgical technique of sandwich mucosal flap surgery attempted to treat mucosal bridge is highly effective for voice improvement with satisfactory phonetic results.
