Exclusive Endoscopic Partial Ossicular Replacement Prosthesis (PORP)

To begin, prepare all the necessary surgical tools and equipment for the procedure. Assess the size of the defect, and choose the appropriate size of the implant. After carrying the prosthesis towards the tympanic cavity, position the foot of the PORP precisely onto the stapes head using a microneedle.

Cover the head of the prosthesis with cartilage, and ensure that the implant slightly tents the tympanic membrane. The overall graft intake rate showed a success rate of 98.3%Preoperatively, the average air-bone gap was 24.30 decibels, whereas after surgery, the average air-bone gap significantly reduced to 16.80 decibels.
