This study investigated the application of combined ossicular replacement prosthesis（The Kurz Omega Connector+TORP） in type Ⅲ tympanoplasty, and compared the surgical effect with traditional TORP. Twenty patients with unilateral chronic suppurative otitis media diagnosed in the Department of Otorhinolaryngology, Sun Yat-sen Memorial Hospital of Sun Yat-sen University from January 2019 to June 2020 were included in this study.All the patients were treated with intra-auricular incision with a microscopic approach（tympanic exploration, lesion clearance+type Ⅲ tympanoplasty）. According to the placement of different types of ossicular replacement prosthesis in the ossicular chain reconstruction of type Ⅲ tympanoplasty, the patients were divided into two groups: the traditional TORP group（=10） and the combined ossicular replacement prosthesis（The Kurz Omega Connector+TORP） group（=10）. All patients underwent pure tone audiometry before and 1 year after the operation, and the average hearing threshold and air-bone conduction difference（ABG） were compared between the two groups before and after the operation. The reconstruction of the ossicular chain was completed successfully in all patients. Endoscopic examination showed that the epithelialization of the operative cavity was good and the repair of the tympanic membrane recovered well one month after the operation. There was no significant difference in preoperative mean airway threshold between the combined ossicular replacement prosthesis and the traditional TORP group （74.13[41.50，80.50] dB vs 74.25[44.81，82.50] dB, >0.05）, there was no significant difference in preoperative ABG （55.63[21.50，61.25] dB vs 54.13[23.63，60.38] dB, >0.05）. After the operation, the ABG of the combined auriculus group was significantly lower than that of the traditional operation group （12.00[5.75，24.56] dB vs 34.88[14.19，46.44] dB, <0.05）. Conclusion: The combined ossicular replacement prosthesis（The Kurz Omega Connector+TORP） can increase the stability of hearing reconstruction and improve hearing in type Ⅲ tympanoplasty.

Optimal Position and Orientation of an Ossicular Accelerometer for Human Auditory Prostheses.

In this study, a method for determining the optimal location and orientation of an implantable piezoelectric accelerometer on the short process of the incus is presented. The accelerometer is intended to be used as a replacement for an external microphone to enable totally implantable auditory prostheses. The optimal orientation of the sensor and the best attachment point are determined based on two criteria-maximum pressure sensitivity sum and minimum loudness level sum.

Aim: To evaluate the audiometric results of tympanoplasty with stapedectomy and insertion of a synthetic total ossicular replacement prosthesis (TORP).
Material And Methods: Retrospective observational study conducted on a cohort of 15 patients (16 ears) aged 10 to 58 years (mean: 36 years) with chronic otitis media (COM) and tympanosclerosis (n=9), stapediovestibular ankylosis (n=3), minor aplasia (n=3) or post-traumatic ossicular dislocation (n=1). Treatment consisted in tympanoplasty with stapedectomy and TORP placement by the same operator, between December 1, 2012 and January 30, 2023, in a French university hospital department, with follow-up ranging from 2 to 92 months (mean: 24 months).

Article Synopsis
- The study investigates how the connection quality between different types of prostheses and the stapes head affects the success of partial ossicular chain reconstructions in conductive hearing loss cases.
- It uses a standardized procedure to compare the coupling quality of various prostheses, including clip and bell types, using 12 temporal bones in a controlled model.
- Results indicate that all prosthesis types provide effective sound transmission with minimal vibrational loss and distortion, suggesting that while the coupling method may impact practical aspects, it does not significantly affect sound performance.

Retrospective analysis of clinical data of 123 patients with atticotomy, exploring the clinical characteristics of patients undergoing atticotomy and the efficacy of hearing reconstruction methods. 123 patients with atticotomy were divided into three groups according to the ossicular chain treatment method: preservation of the ossicular chain group（37 cases）, cartilage elevation of stapes group（49 cases）, and PORP group（37 cases）. The clinical characteristics of patients with atticotomy, preoperative and postoperative hearing levels of the three groups of patients, and postoperative complications were analyzed.

Article Synopsis
- - Chronic ear diseases often lead to ossicular defects, requiring the use of ossicular reconstruction prostheses like TORP (total ossicular replacement prosthesis) and PORP (partial ossicular replacement prosthesis) to restore hearing continuity.
- - Research shows that using a malleus to footplate reconstruction yields better mechanical outcomes than malleus to stapes superstructure, but long-term effectiveness of TORP versus PORP remains unclear.
- - A study involving 60 patients with Austin type A defects found significant post-operative improvements in hearing for both TORP and PORP groups, with 90% of patients showing mild hearing loss after surgery compared to their pre-operative condition.
