Voice Quality Assessment In Cases Of Vocal Fold Gaps After Single Growth Factor Injection, Amr Roushdyel Badrawy, Asmaa Abdel Hamid, Israa Eltaweel, Azza Abdel Aziz Azzam

Journal of Medicine in Scientific Research

In severe vocal fold (VF) lesions, deposits of disorganized, thick collagen bundles and little hyaluronic acid (HA) are deposited in the superficial layer of lamina propria (SLP). These changes lead to severe dysphonia and aspiration, which could be complicated by fatal pneumonia. Unfortunately, no specific treatment has been recognized due to unpredictable VF regeneration. Current progress in regenerative medicine has allowed the development of tissue engineering techniques using cells, scaffolds, and growth factors (GFs). Extrinsic GFs application could help in the induction of the regenerative process. The work aims to assess the voice quality after a single GF injection of …
