Reinke's edema (polypoid degeneration of the vocal cord) involves pathological accumulation of fluid in which anatomical layer?
- A Superficial layer of the lamina propria (Reinke's space) between the squamous epithelium and the vocal ligament ✓
- B Deep layer of the lamina propria forming the vocal ligament
- C Submucosal glands of the laryngeal saccule
- D Vocalis muscle (thyroarytenoid, internal division)
Correct answer: A. Superficial layer of the lamina propria (Reinke's space) between the squamous epithelium and the vocal ligament
Explanation
Reinke's space is the potential space within the superficial layer of the lamina propria (SLP) of the true vocal cord, bounded superficially by the squamous epithelium, deeply by the vocal ligament, and laterally by the arcuate line. Edematous fluid accumulates here in Reinke's edema — associated with smoking and voice abuse. Treatment is microsurgical decortication (stripping) with careful preservation of the underlying vocal ligament to prevent scarring and permanent dysphonia.
