Other Tests

Videostroboscopy

See the list below:

  • Videostroboscopy reveals a decreased or absent mucosal wave, and often the medial edge of the injured cord does not approximate to the other during phonation. In addition, the cords may be at different levels, leading to incomplete closure. [4, 5]

  • In sulcus vocalis, videostroboscopy reveals an area of decreased mucosal wave corresponding to the sulcus and more clearly shows associated incomplete closure.

Histologic Findings

Obtaining pathology slides from the original surgery may be helpful. The size of the resected specimen and the presence of muscle or dense collagen and elastin fibers indicate a deep dissection, which is more likely to involve scar formation.
