Introduction: Idiopathic sensorineural hearing loss of 30 decibels (dB) or more over at least three contiguous audiometric frequencies with an onset of less than 3 days is referred to as sudden sensorineural hearing loss (ISSNHL) and is known as an ENT (ear, nose, and throat) emergency. When a patient’s hearing suddenly deteriorates, they become confused, anxious, and worried. One of the primary therapies for sudden sensorineural hearing loss is intratympanic steroids. Intratympanic injections of platelet-rich plasma (PRP) improve inner ear hair cells, which enhances hearing. Aim: To show the safety and efficacy of intratympanic PRP injection in the management of ISSNHL in comparison with intratympanic steroid injection. Methods: The study group was comprised of 100 patients who had experienced ISSNHL within 30 days with no retrocochlear pathology, as demonstrated by a negative MRI scan. 50 patients received 6 intratympanic steroid injections, while the remaining 50 patients received 2 intratympanic injections of PRP at a 1-week interval. Results: A total of 39 patients with PRP injection noted an improvement in their hearing of 25 db after 2 weeks and of 30 db after 2 months, with improved speech discrimination of 26% after 2 weeks and of 28% after 2 months. 31 patients with intratympanic steroid injection noted an improvement in their hearing of 18 db after 2 weeks and of 22 db after 2 months, with improved speech discrimination of 21% after 2 weeks and of 24% after 2 months. Conclusions: PRP appears safe and efficient for the treatment of ISSNHL, with a low cost and no systemic side effects, as with oral steroids. Therefore, such research should be continued.
