Audiovestibular Dysfunction and Hearing Loss in Patients with Psoriasis and Psoriatic Arthritis

Abstract

Psoriasis is now considered a T cell-mediated chronic systemic inflammatory disease rather than only a simple skin disease. The relationship and coexistence of this common disease with many other comorbidities have gained increasing attention in recent years. Although psoriatic skin lesions are seen frequently in the auricle and external auditory canal, there are not many studies evaluating the possible effect of psoriatic disease (psoriasis with or without joint involvement) on the auditory system. Hearing impairment detected in psoriasis patients is mostly seen as subclinical hearing loss at high frequencies, but it can also have a significant impact on patients' health and quality of life due to the possible risk of developing sudden sensorineural hearing loss. In this chapter, the frequency, pattern, and patient-related risk factors of hearing impairment and audiovestibular dysfunction in patients with psoriasis and psoriatic arthritis were extensively reviewed and discussed. In conclusion, it was emphasized that subclinical sensorineural hearing loss is a neglected but an important comorbidity in patients with psoriasis and psoriatic arthritis. The relationship between psoriatic disease and audiovestibular dysfunction supports the need for further studies aimed at better identification of the underlying pathogenic mechanisms, and accordingly to update diagnostic and even treatment approaches.
