ABSTRACT
Objective: To analyze subjective and objectively the results after the injection of
autologous plasma gel in patients with glottic insufficiency.
Material and Method: A prospective, observational, descriptive and longitudinal
study was done in patients with dysphonia secondary to glottal insufficiency attended
at the Laryngology and Phonosurgery Clinic of the CMN 20 de Noviembre, ISSSTE,
Mexico, from August to December 2014. There were three assessments: by de 10-item
Voice Handicap Index questionnaire (VHI-10), maximum phonation time (MPT) and
laryngovideostroboscopy prior to injection. The sample for the plasma gel preparation
was taken with the posterior percutaneous injection through the thyrohyoid membrane.
The same evaluations were applied at 4 and 8 weeks after the intervention.
Results: Six female patients were included with average age of 67 years. A statistically
significant difference was observed between the pre-intervention VHI-10 and at 4 and
8 weeks after application (p ‹ 0.002), as well as the MPT before and at 4 and 8 weeks
(p ‹ 0.001). By laryngovideostroboscopy was observed a complete glottic closure in
100% of the sample at 4 weeks and in 67% of patients at 8 weeks; 33% of the remaining
patients continued with lower glottic insufficiency.
Conclusion: Autologous plasma gel medialization injection is a useful option for
temporary treatment in patients with glottic insufficiency.
