BILATERAL SUDDEN SENSORINEURAL HEARING LOSS (SSHL) WITH HYPOKALEMIC PERIODIC PARALYSIS (HPP)

Sudden hearing loss is a medical emergency for which definitive diagnosis and treatment is still largely unknown. SSHL generally refers to hearing loss of sensorineural origin. SSHL is defined as 30 dB or more sensorineural hearing loss over at least three contiguous audiometric frequencies occurring within 3 days or less. The incidence of SSHL is estimated to be 5-20 per 100000 persons. The highest incidence occurs between 50- 60 years of age, and the lowest incidence is between 20- 30 years of age, but average age of onset is usually between 40 and 50 years, and of the patients suffering from SSHL, 4-10% are bilateral.4 SSHL has several possible etiologies, including circulatory, autoimmune, membrane rupture, trauma, tumor and viral origins….
