“…From our 6-year experience in endoscopic ear surgery, we have come to believe that new anatomical [1] and physiological [2,3] concepts should be introduced in middle ear surgery. Endoscopic approaches to middle ear are generally very preservative techniques, as thoroughly described in our earlier articles, and in most cases they avoid mastoidectomy [4] due to the possibility of an around-the-corner view of most of the inaccessible spaces D. Marchioni in the tympanic cavity [5,6].…”

“…These papers bring about a new approach for known disorders, such as the cholesteatoma, introducing new physiological and anatomical concepts concerning aeration of the tympanic cavity and mastoid cells in order to understand the disease and its surgical treatment [7][8][9] . Today, the endoscope plays an important role in cholesteatoma surgery in some centers in the world; however, there are still very few papers in the literature discussing the possible benefits of stapes surgeries made solely with the use of the endoscope, especially those studies based on the exposure of the oval window niche and stapes visibility.…”

St apedotomies are perfomed with the aid of surgical microscopes. However, the microscope has some limitations and may cause complications such as damage to the chorda tympani nerve. There are just a few cases and no series published on the use of sino-nasal endoscopes in stapedotomies.Objectives: a) To investigate the feasibility of using sino-nasal endoscopes in stapedotomies, focusing on the visualization of important structures. b) To show initial results, discuss possible advantages and disadvantages of this instrument.Methods: 15 patients with otosclerosis were selected to undergo stapedotomies in 2010. The data and surgery videos were analyzed retrospectively (study case series). The anatomical conditions of the oval window niche and surgical steps were described and used to assess possible benefits of such procedures. Results:The surgeries were performed with endoscopes only and all relevant anatomical structures were visualized without difficulty. No complications were observed and 14 of the 15 patients reported improvement of their hearing, confirmed by postoperative audiological tests. Conclusion:Totally endoscopic stapes surgeries are technically feasible, safe and promising. In this small series, the main advantages were: virtually no trauma to the chorda tympani nerve and excellent vision. The disadvantages were the lack of stereoscopic vision, having to work with one hand only and the learning curve. Braz J Otorhinolaryngol. 2011;77(6):721-7. ORIGINAL ARTICLE BJORL

“…At times this space is contiguous with the sinus tympani, if the ponticulum is rudimentary in size. The anatomy of these spaces has been well demonstrated and beautifully illustrated in recent publications by Holt and Marchioni et al 7,8 Disease enters the sinus tympani by migrating medially along the lenticular process and stapes superstructure, then posteriorly along the plane of the promontory. This direction of growth can be appreciated in cases of retraction pockets arising from posterior middle ear collapse ( Fig.…”

Fig. 6.1 Pars tensa cholesteatomas begin as retraction pockets in the posterosuperior quadrant and travel medially toward the promontory and posteriorly into the sinus tympani. The stapes superstructure and lenticular process act as a conduit for the spread of disease from the tympanic membrane to the promontory.This document was downloaded for personal use only.

Pyramidal eminence and subpyramidal space: An endoscopic anatomical study

Abstract: Endoscopic exploration of the middle ear may guarantee a very good exposure of retrotympanic structures, allowing detailed anatomical descriptions of hidden areas. Improvement in our knowledge of the anatomy may decrease the possibility of residual disease during cholesteatoma surgery.
