About this study

Official title: Safety and Efficacy of Serial Platelet-Rich Plasma Injections for Treatment of Vocal Fold Atrophy, Scar, and/or Sulcus Vocalis

This study will investigate the safety and efficacy of four serial monthly vocal fold injections of platelet-rich plasma to treat dysphonia secondary to vocal fold atrophy, scar, and/or sulcus vocalis with glottal insufficiency

Read the detailed description

Vocal fold atrophy, scar, sulcus vocalis, glottal insufficiency with resulting dysphonia is a condition affecting millions of aging Americans, up to 35% of those 65 or older. Currently used treatment methods include voice therapy, injections of inert fillers, and laryngeal framework surgery. These modalities are imperfect with voice therapy requiring considerable time commitment, filler injections generally temporary in benefit, and surgery with increased risks. The investigators intend to conduct a single-arm study to assess the safety and efficacy of autologous platelet-rich plasma (PRP) injection for vocal fold atrophy, sulcus vocalis and scar. PRP is a substance purified from the patient's own blood that consists of platelets, growth factors, and other regenerative molecules that have been shown to promote rejuvenation in a variety of tissue types. Patients with vocal fold atrophy, sulcus vocalis, and scar identified in the USC Voice Center will be offered participation in a study to receive serial PRP injections in one vocal fold. Outcome measures evaluated pre- and post-injection and over follow-up visits will include various patient reported quality of life indices, objective clinical assessments of voice, and laryngeal videostroboscopy examinations. The investigators hypothesize that serial PRP injections will significantly improve vocal fold mucosal volume, morphology, and dysphonia in these patients with no adverse side effects.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of Treatment-Emergent Adverse Events as assessed by FDA/CBER Adverse Event Severity Grading Scale

    Adverse event severity grading scale from 1 to 4, with grade 1 as mild, grade 2 as moderate, grade 3 as severe, and grade 4 potentially life-threatening

    Measured: 4 months

Secondary outcomes (3)
  1. Voice-Related Quality of Life as assessed by Voice Handicap Index-10 (VHI-10) and Vocal Fatigue Index (VFI)

    VHI-10 is a patient questionnaire with 10 statements rated from 0 to 4 with overall scale 0-40; VFI is a patient questionnaire with 19 statements rated from 0-4 with overall scale 0-76.

    Measured: 4 months

  2. Objective Vocal Quality as assessed by experts using the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) instrument

    Blinded evaluations of audio voice recordings will be performed by laryngologists and speech-language pathologists using the CAPE-V, which grades overall severity, roughness, breathiness, strain, pitch, and loudness from 0-100.

    Measured: 4 months

  3. Vocal Fold Appearance as assessed by experts using a modified version of the Voice-Vibratory Assessment with Laryngeal Imaging (VALI) form

    Blinded assessments of recorded laryngeal videostroboscopy exams will be performed by laryngologists and speech-language pathologists using a modified version of the VALI, which is a graphical rating form to grade various components seen on stroboscopy.

    Measured: 4 months
