Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Assessment of the efficacy of Intratympanic platelet rich plasma injection for treatment of idiopathic suden sensorineural hearing loss

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Sensorineural hearing loss is the collective term for hearing damage to the cochlea and auditory nerve and is by far the most common type of hearing loss in adults, accounting for over 90% of all cases. Sensorineural hearing loss is a heterogeneous disorder, which can arise due to damage to pathway for sound impulses from the hair cells of inner ear to auditory nerve and less commonly brain.

Sensorineural hearing loss is a challenge to physicians, as it progresses with age and causes significant reductions in quality of life and there are no treatments to reverse its effects, other than sound amplification with the use of hearing aids or direct auditory nerve stimulation via cochlear implantation.

Platelet-rich Plasma (PRP) Therapy is a cutting-edge procedure that is revolutionizing the hearing loss and deafness. Intratympanic instillation of Platelet-rich Plasma (PRP) does wonder to the hair cells of inner ear, thus improving the hearing.

Study Groups

platlet rich plasma

Group Type EXPERIMENTAL

Platelet Rich Plasma

Intervention Type BIOLOGICAL

Sample of patient's blood drawn at time of Treatment; the blood drawing occurs with addition of anticoagulant such as citrate dextrose A to prevent platelet activation prior to its use.

Obtain whole blood by venipuncture in acid citrate dextrose (ACD) tubes. Centrifuge the blood using a 'soft' spin. Transfer the supernatant plasma containing platelets into another sterile tube (without anticoagulant).

Centrifuge tube at a higher speed (a hard spin) to obtain a platelet concentrate.

The lower 1/3rd is PRP and upper 2/3rd is platelet-poor plasma (PPP). At the bottom of the tube, platelet pellets are formed.

PRP activation prior to injection. PRP can be activated exogenously by calcium chloride.

local anesthesia in external auditory canal

Intervention Type DRUG

local anesthesia cream (lidocaine cream) will be applied in external auditory canal for 15 minutes

Intratympanic Injection

Intervention Type PROCEDURE

0.5-1 ml of PRP will be injected in middle ear cavity in round window niche Using microscope or endoscope.
