Reinke's oedema (polypoid corditis) is characterised by accumulation of oedema in which space of the vocal cord?
- A Deep to the thyroarytenoid muscle
- B Submucosal space between the epithelium and vocalis muscle (Reinke's space) ✓
- C Within the vocalis muscle fibres
- D Between the thyroid lamina and the thyroarytenoid muscle
Correct answer: B. Submucosal space between the epithelium and vocalis muscle (Reinke's space)
Explanation
Reinke's space is a loose gelatinous potential space between the squamous epithelium and the vocal ligament (intermediate and deep layers of lamina propria) of the vocal cord. In Reinke's oedema (associated with smoking and voice abuse), this space fills with oedematous fluid, causing the characteristic translucent, bilateral polypoid swelling. Treatment involves voice rest, smoking cessation, and microlaryngoscopic aspiration of the oedema with mucosal reduction.
