“…However, the problem with this approach is that the space for drilling is small compared with the approach from the retroauricular incision to the mastoid. Cadaveric examination revealed that the geniculate ganglion could be identified via the route from Shambaugh's incision to the upper tympanic cavity by scraping the zygomatic bone in front of the ear canal (9). PEES type A is similar to this approach; moreover, we determined that the approach developed in cadaver research in a previous report is possible to be performed in clinical cases.…”

Objectives We developed a novel keyhole surgery, named “percutaneous endoscopic ear surgery” (PEES), with the aim of further reducing the invasiveness of otologic surgery. We reported the cases we encountered and retrospectively analyzed the invasiveness of PEES. Methods We analyzed the ears of eight patients who underwent PEES for mastoid lesions that could not be manipulated with transcanal endoscopic ear surgery (TEES) at our hospital between July 2021 and November 2022. We performed PEES alone in three patients, including one case of type A (preauricular incision) and two cases of type B (retroauricular incision). The last five patients underwent combined endoscopic ear surgery, which is simultaneous PEES and TEES. In these cases, one patient underwent type A PEES, and four patients underwent type B PEES. Results PEES was performed in all patients without converting to conventional microscopic mastoidectomy. The mean length of skin incisions was 19.1 ± 4.5 mm, which was smaller than that in conventional mastoidectomy. In all cases, the average length of the major axis of the keyhole was <10 mm, indicating that sufficient minimally invasive surgery was achieved. The average depth from the keyhole to the deepest site was 21.6 ± 8.9 mm. There was no change in the mean hearing level before and after the surgery. Conclusion PEES is a minimally invasive procedure for manipulating lesions in the mastoid. In addition, the combination of PEES and TEES is an ideal, minimally invasive procedure that can be used to treat all regions of the temporal bone.

“…The approaches utilized for facial nerve decompression (FND) include the trans mastoid, middle cranial fossa, and trans labyrinthine approaches depending on the site of injury and hearing status ( Fernandez et al., 2021 ). The middle cranial fossa approach has been used for nerve decompression in patients with serviceable hearing and those whose affected area span from the geniculate ganglion (GG) and labyrinthine segment to metal portion of the facial nerve ( Aslan et al., 2014 ).…”
