“…An important advantage of TEES is that it can preserve the mastoid mucosa, which plays a crucial role in regulating middle ear pressure. Preservation of the mastoid mucosa can prevent the recurrence of cholesteatoma by normalizing middle ear pressure (13,14); thus, we believe that PEES, which can preserve the mastoid mucosa, is a promising procedure that enables cholesteatoma surgery with less recurrence.…”

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.

“…They demonstrated that individuals who received tympanomastoidectomy experienced more middle ear retraction than those who had tympanoplasty without mastoidectomy. 14,15 As a result, they promoted against intervening during surgery on well-ventilated mastoid cells. 14 Bonding hypothesized that the mastoid cell system was responsible for pediatric tympanomastoidectomy failures.…”

A clinical study of mastoid ventilation tube in tympanoplasty

Background: A ventilated middle ear space is an essential component of a functioning middle ear transformer mechanism. A mastoid ventilation tube (MVT) placed post-aurally in the antrum near the aditus is used in this study for the benefit of improvement in results of tympanoplasty. In support of this concept, very few experimental documents are reported. Aims and Objectives: The aims of this study were to find out if the MVT has any effect on the outcome of tympanoplasty in cases of chronic suppurative otitis media (CSOM) tubo-tympanic disease. Materials and Methods: This study was performed in 50 cases which were selected from the total number of cases using stratified random sampling method. In the research, patients with CSOM, who did not respond to medical therapy and required a combined approach tympanoplasty, were enrolled. Patients who needed just myringoplasty and those found to have cholesteatoma intraoperatively were not included in the research. Results: The study showed significant improvement in graft uptake, air-bone closure, and hearing in cases with MVT, thus resulting in better success rate in cases with MVT than cases without MVT. Furthermore, most of the cases had sclerosed mastoids and very few cases had complications such as MVT block and post-operative discharge. Conclusion: The MVT had a beneficial effect on the final outcome of combined approach tympanoplasty in cases of CSOM tubo-tympanic type active stage.
