The scheme illustrates the technique of perilymph sampling under an endoscope guide. The red triangle area delimits the space where it is possible to identify the round wound niche (green circle). Once the round window (RW) has been identified, it is possible to go through the tympanic membrane (TM) using the device proposed by St. Peter et al. [14] The microneedle will come out from the device only after perforation of the TM just to reach the RW and perform the perilymph sampling.
