“…In the last three decades, endoscope has been increasingly used in endonasal surgery that nowadays is simple and common [1]. Since the last decade, endoscope was used in otology firstly as a diagnostic tool then during middle ear surgery [2][3][4][5][6][7]. Endoscopy provided an important and sometimes unexpected detailed middle ear anatomy particularly for the hidden recesses such as the sinus tympani (ST) and the supratubal recess (STR).…”

Background: High-resolution computed tomography (HRCT) magnifies the role of preoperative imaging for detailed middle ear anatomy particularly its hidden area. The purpose of the current study was to assess the sinus tympani (ST) and supratubal recess (STR) by HRCT, to create CT classification of the STR depth, and to study the relationship between ST types and the new STR grades. Results: In HRCT of non-pathological temporal bones of 100 subjects (200 ears), measurements of the STR and ST were calculated, registered, and analyzed. The depth of the STR was classified into grade 1 with depth less than 3 mm, grade 2 with depth ranged between 3 and 5 mm, and grade 3 with depth more than 5 mm. The mean STR length, width, and height were 4.17 ± 0.86, 3.55 ± 0.65, and 3.64 ± 0.7 mm, respectively, while the ST mean length and width of were 2.52 ± 0.5 and 1.82 ± 0.78 mm, respectively, without significant differences between either sexes or sided. The ST types were found to be type A in 56 ears (28%), type B in 142 ears (71%), and type C in 2 ears (1%). The STR grading was grade 1 in 12 ears (6%), grade 2 in 160 ears (80%), and grade 3 in 28 ears (14%) without significant relationship between ST types and STR grading (P = 0.3). Conclusion: The current study provided reliable and applicable methods of CT assessment of STR and ST that can help to predict the degree of surgical visibility of the ST and STR during ear surgery.

“…Since the last decade endoscope was used in otology just as a diagnostic tool and never over the eardrum. Recent development of endoscopy in middle ear surgery [4][5][6][7][8][9][10][11] has permitted an extremely and unexpected detailed view of the ''in vivo'' anatomy of middle ear. Exploration of hidden recesses like the sinus tympani, the anterior epitympanic space, and the protympanic space with such a magnification is almost impossible with microscopic traditional approaches.…”

Good knowledge of anatomy is fundamental for every surgeon. Middle ear anatomy is really complex and sometimes is challenging for otologists, who need to explore every single compartment for a radical removal of pathology. With introduction of the endoscope in middle ear surgery, anatomy of middle ear spaces has become wider and clearer due to a better magnification and to the possibility to look ''behind the corner''. This article is a review of the state-of-art of endoscopic middle ear anatomy with description of every compartment, with particular attention to ventilation pathways and middle ear folds.

The advantages and limitations of the microscope of choice for the treatment of diseases of the middle ear. The wide-angle view provided by the endoscope enables transcanal access to the tympanic cavity, and its otherwise recess, and hypotympanum. These areas are the primary sites of disease and surgical failure to cure. The endoscope also allows an all encompassing view of the three main elements in tympanoplasty surgery: The ear canal, tympanic membrane, and the tympanic ring. This report is a summary transcanal operative endoscopy as the primary approach to the management of middle ear disease.
