Ossicular discontinuity is the most common cause of conductive hearing loss. The use of ossicular graft material in ossicular chain reconstruction significantly improves the result in hearing. This study was conducted to compare and analyze the outcome of ossicular reconstruction using autologous conchal cartilage and homologous septal cartilage in terms of hearing results and graft uptake rates. Study design Randomized clinical trial. Study included 100 patients visiting the ENT department of government medical college...

This study aimed to evaluate the benefit but also the extrusions, dislocations, and failures of a titanium incus prosthesis along with the long-term audiological outcomes. We prospectively collected data from 139 patients undergoing ossiculoplasty using the Fisch titanium incus prosthesis between 2001 and 2016. Overall, 126 patients with at least 6 months of follow-up (mean 4.5 years, range 6-155 months) were analyzed. Patients were grouped as "extrusion" (n = 9, 7%) if the prosthesis extruded, "failure" (n = 22, 18%) if a reoperation was needed concerning the prosthesis, and "stable" (n = 95, 75%) if the prosthesis remained functional in the middle ear...

Aim of the present study is to evaluate the long term results of ossiculoplasty using titanium clip prosthesis. A retrospective analysis with prospective follow-up has been done including for all patients who had a Clip-PORP implanted between the years 2002-2013. Following this, audiometric hearing results were measured with clinical examination including otoscopy and quality of life evaluation using Glasgow benefit inventory. 48 patients (51 ears, 29 men, 19 women, average age 44.1 years) received followed up after an average duration of 6...

Techniques and biomaterials for reconstructive middle ear surgery are under steady, ongoing development. At the same time, clinical post-surgery results are evaluated to determine success or failure of the therapy. Routine quality assessment and assurance is of growing importance in the medical field, and therefore also in middle ear surgery. The exact definition and acquisition of outcome parameters is essential for both a comprehensive and detailed quality assurance. These parameters are not the audiological results alone, but also additional individual parameters which influence the postoperative outcome after tympanoplasty...

Tympanoplasty was conventionally performed using a microscope for decades. However, since the endoscope began to be used in middle ear surgery in the 1970s, endoscopic tympanoplasty has gained increasing attention. The main objective of this study was to compare endoscopic and microscopic tympanoplasty with and without ossiculoplasty, demonstrating the potential advantages, disadvantages, and outcomes of each. This retrospective study included 126 patients with chronic otitis media who received tympanoplasty from 2013 to 2015 in our hospital...

INTRODUCTION: The lenticular process of the incus succumbs to necrosis in chronic otitis media. Few researchers have addressed the issue of autograft incus preservation in the soft tissue of the tragus or mastoid cavity. Nonetheless, preservation of the incus in this method during the second stage of ossiculoplasty is a subject that is still up for debate. This study was carried out to demonstrate the hearing outcome after a modification of the incus interposition technique, which involved preserving it in the periauricular soft tissue...

INTRODUCTION: The middle ear ossicles form a semi rigid chain in the middle of the ear for conduction and amplification of sound waves from the tympanic membrane to the inner ear. Although, our knowledge of the ear ossicles dates back to the 15(th) century, and various studies have been carried out on their morphometry, morphology, anomalies, embryology, function and structure throughout the world, information about the morphology of middle ear ossicles is meagre in Indian subjects. AIM: To find out the morphological variations of middle ear ossicles of right and left sides...

OBJECTIVE: This study aimed to compare the functional and anatomical outcomes of ossiculoplasty using an autograft incus or a titanium partial ossicular replacement prosthesis for reconstructing Austin type A ossicular defects. METHODS: Patients with Austin A ossicular defects were randomly divided into two groups: one group underwent ossiculoplasty with an autologous incus (the autologous incus group) and the other underwent ossiculoplasty with a titanium partial ossicular replacement prosthesis (the titanium prosthesis group)...

CONCLUSION: A tentative conclusion was made that the finite element method can be used to investigate the fatigue life of the tympanic membrane after ossiculoplasty; the main reason of the extrusion of the tympanic membrane may not be blamed to the fatigue mechanism under normal sound pressure. OBJECTIVE: This study was to investigate the extrusion of the prosthesis from the tympanic membrane at post-ossiculoplasty by finite element method. METHODS: A finite element model of the human middle ear has been constructed and used as the model of the constructed middle ear at post-ossiculoplasty...

OBJECTIVES: To determine if the OOPS index is predictive of long-term hearing results after ossiculoplasty. STUDY DESIGN: Case series with retrospective chart review. SETTING: Tertiary care otology practice. PATIENTS: Adult and pediatric patients (3-88 years of age). INTERVENTIONS: Ossiculoplasty with cartilage tympanoplasty, with or without mastoidectomy. OUTCOME MEASURES: Primary outcome measures included short-term hearing results (pure-tone average air-bone gap [PTA-ABG] measured between 60 days and 1 year after surgery), long-term hearing results (PTA-ABG measured ≥5 years after surgery), and the rate of successful ABG closure to ≤20 dB...

The objective of the study was to improve the functional outcomes of the treatment in the patients presenting with chronic otitis media by means of the combined application of platelet-enriched plasma and the biologically compatible cyanacrylate-based glue for the fixation of the reconstructed auditory ossicular chain. The functional results of the surgery were evaluated within 1, 3, and12 months after the intervention making use of tonal threshold audiometry. It was shown that the use of the platelet-enriched plasma with its subsequent fixation by the biologically compatible cyanacrylate-based glue enhances stability of the implanted prosthetic elements, reduces the risk of their displacement during the postoperative period due to the formation of the cicatrical tissue between the structural components of the middle ear...

To investigate the effects of surgery type [intact canal wall (ICW) or canal wall down (CWD) mastoidectomy] and different ossiculoplasty materials on hearing outcome in single-staged cholesteatoma surgery. A retrospective case-control study. A total of 116 cases (97 adults, 29 children) underwent surgery, including ossiculoplasty, between 2012 and 2015 for cholesteatoma. Patients who had undergone surgery for the first time, and whose grafts were successful, were included in the study. Patients with adhesive otitis media, unsuccessful grafts, revision and recurrent cases, radical mastoidectomy, and craniofacial anomalies were excluded...

BACKGROUND: Bone cement is used for ossicular chain repair and revision stapes surgery. Its efficient use requires cautious removal of mucosa from the ossicles. This paper reports a technique for easy, fast and safe removal of this mucosa prior to cement application. It consists of the application of monopolar electrocoagulation on the ossicles prior to bone cement application. METHODS: The outcomes of six cases of revision stapes surgery and seven cases of partial ossiculoplasty, conducted between 2007 and 2012 using this new technique, were evaluated...

HYPOTHESIS: Electromagnetical excitation of ossicular vibration is suitable for middle ear transmission measurements in the experimental and clinical setting. Thereby, it can be used as a real-time monitoring system for quality control in ossiculoplasty. BACKGROUND: Positioning and coupling of middle ear prosthesis are a precondition for good postoperative hearing results, but at the same time completely dependent upon the surgeon's subjective judgment during surgery...

OBJECTIVE: To assess the effectiveness of glass ionomer bone cement (GIBC) in lateral attic wall reconstruction after primary acquired attic cholesteatoma surgery. MATERIALS AND METHODS: This prospective study was conducted on twenty children collected from the ENT outpatient clinics of a secondary and tertiary hospital. All patients presented with chronic suppurative otitis media with cholesteatoma of the primary acquired attic type. All patients underwent intact canal wall mastoidectomy (ICWM) with a transcanal atticotomy to address primary cholesteatoma involving the attic and the supratubal recess...
