A Rare Case of Co-occurring Ménière's Disease and Red Ear Syndrome.

Ménière's disease (endolymphatic hydrops) is a multifactorial syndrome affecting the inner ear, typically distinguished by attacks of variable frequency which include vertigo, aural fullness, tinnitus, and fluctuating hearing loss. Red ear syndrome is characterized by paroxysmal erythema of the external ear, either unilaterally or bilaterally, with pain, burning sensation, and/or swelling. Both conditions have complex and heterogeneous etiologies. Ménière's disease and red ear syndrome have not previously been associated in the literature, yet they can have overlapping characteristics. This case describes the co-occurrence of Ménière's disease and red ear syndrome in the right ear of a 43-year-old female patient. It highlights the potential association between the two conditions and proposes possible pathophysiological mechanisms linking them, including atypical migraine, autonomic dysregulation, vascular permeability, and hormonal factors.
