The prognostic value of mucociliary clearance in predicting success in tympanoplasty
1993
AbstractMucociliary and equipressive eustachian tube functions have been studied, using saccharin solution (five per cent sodium saccharinate) and tubal manometry respectively, in 58 ears with chronic disease undergoing tympanoplasty. The position of the perforation site determines the results as the poorest results are obtained from the posterior ones, positive cases (47 per cent) and mean transport time (37.7 minutes), compared to the greater percentage of positive cases (86 per cent) and mean transport time (22.2 minutes) for anterior perforations.When both parameters are analysed together there is a direct relationship between normal equipressive function and normal mucociliary transpor…
The Role of Diffusion-Weighted Magnetic Resonance Imaging in Cholesteatoma Diagnosis and Follow-up: Study With the Diffusion PROPELLER Technique
2012
Abstract Introduction and objectives The diagnosis of cholesteatoma is based on clinical evaluation and computed tomography. New non-echo-planar diffusion-weighted magnetic resonance imaging (MRI) techniques, without intravenous contrast, are capable of differentiating cholesteatoma from inflammatory tissue, cholesterol granuloma and granulation tissues. The technique is very helpful in differential diagnosis of cholesteatoma, mainly after canal wall-up tympanoplasty surgery, to avoid routine second-look surgery in these patients. Congenital cholesteatoma and difficult cases can be detected and correctly diagnosed as well. The aim of this study was to evaluate sensitivity, specificity, posi…
BIOACTIVE GLASS CERAMIC
1983
The practicability of the bioactive glass ceramic Cernvitnl® in ear surgery was tested in animals. The histological findings are presented. Over the last 3 years implants of bioactive glass ceramic were used in humans. Prostheses for the total or partial reconstruction of the ossicular chain and the reconstruction of the bony wall of the outer ear canal were fashioned. We have conducted about 300 tympanoplasties and 60 total or partial reconstructions of the bony wall of the outer ear canal. The otoscopic and functional results were satisfactory.
Tissue reactions to glass ceramics in the middle ear
1981
The bioactive glass ceramic "Ceravital" was used to fashion prostheses for the replacement of various ossicles in the middle ear. They were tested in 70 rabbit ears, where they were accepted in osseous areas without formation of surrounding fibrous tissue. Histological examinations regularly showed an osseous bond with the surrounding bony tissue. Mucous membrane covered these ossicular chain prostheses and showed no evidence of inflammatory reactions. Glass ceramic implants were also used to reconstruct the ossicular chain and the posterior wall of the outer ear canal in 100 patients. The functional results were satisfactory in all cases.
Myospherulose des Mittelohres - eine seltene Differenzialdiagnose des Cholesteatoms
2004
Background Myospherulosis is a chronic-inflammatory lesion that is most commonly iatrogenic of origin and occurs in tissues exposed to petrolatum-based products. The disease does not exhibit characteristic symptoms and is therefore not diagnosed in some instances. In previous otorhinolaryngological studies, myospherulosis was mainly found in paranasal sinuses, while only four otitic cases have been reported. Methods A 48-year-old female Egyptian patient suffered from bilateral chronic otitis media that had been treated in Egypt by tympanoplasty. The patient presented few months later at the university ENT department (Mainz) with deteriorated otorrhea and otalgia. Clinical, otoscopical, and …
The Role of Cartilage-perichondrium Tympanoplasty in the Treatment of Tympanic Membrane Retractions: Systematic Review of the Literature.
2022
Abstract Introduction Tympanic retraction is a condition characterized by the displacement of the tympanic membrane toward the structures of the middle ear. Clinically, tympanic retractions can lead to hearing loss, ear discharge and/or ear pain. In most of the cases, however, tympanic retractions are asymptomatic and are found accidentally during an ear, nose, and throat (ENT) examination. This condition has created numerous debates regarding the optimal choice of treatment, especially in the asymptomatic forms. The main controversy is regarding the relationship between retraction and the development of cholesteatoma, which would justify a surgical intervention performed for preventive pur…
Determinants of failure in the reconstruction of the tympanic membrane: A case-control study
2018
Introduction: The recurrence rate after tympanoplasty is variable between 0% and 50%. The causes of failure may be different and frequently interrelated, making the surgical choice difficult and the prognosis not always favourable. In this study, we analysed recurrence rate and the possible causes of failure of tympanoplasty in the treatment of tympanic perforations. Materials and Methods: This prospective case-control study was carried out on patients undergoing tympanoplasty. The main outcome was closure of the tympanic membrane. Results: Among the studied 72 patients, the overall recurrence rate was 19.4%. The average follow-up was 28 months; no recurrence was observed over 12 months of …
Mastoidectomy in surgical procedures to treat retraction pockets: a single-center experience and review of the literature
2022
Abstract Purpose Retraction pocket (RP) is a common event affecting the middle ear when a negative pressure within it causes a retraction of a single part of the tympanic membrane (TM). Patients can be asymptomatic or can experience hearing loss, fullness feeling and/or ear discharge. RP can be stable or develop a cholesteatoma; aim of the study was to investigate if mastoidectomy may play a role in the surgical management of patients suffering from RP, both reporting our experience and discussing the existing literature. Methods Fifty-one patients affected by RP were referred for surgery and randomly divided into two groups. Patients of G1 group underwent tympanoplasty with mastoidectomy, …
Consensus on Treatment of Obstructive Eustachian Tube Dysfunction With Balloon Eustachian Tuboplasty
2020
Abstract Objective There is a great variability in diagnosis of obstructive Eustachian tube dysfunction and its treatment by balloon Eustachian tuboplasty (BET). The aim of this paper was to present a consensus on indications, contraindications, methodology, complications and results after BET. Material & Methods We obtained a consensus on BET, after a systematic review of the literature on BET from 1966 to November 2018, using MESH terms “Eustachian tube and (dilation or dysfunction)”, including a total of 1.943 papers in Spanish, English, German and French. We selected 139 papers with a relevant abstract, including two international consensuses, seven systematic revisions, and two randomi…
Learning curve for piezosurgery in well-trained otological surgeons
2009
Abstract Objective Piezosurgery is an ultrasound instrument (24.7-29.5 kHz) capable of cutting bone without necrosis and nonmineralized tissue damage. The aim of this work has been to determine the time required for a well-trained surgeon to perform otological surgery with the piezoelectric device. Study Design Case series with planned data collection. Sixty-three patients affected by otosclerosis and 63 by chronic otitis media were enrolled. For each disease, patients were divided into three numerically equal groups, with each group assigned to a well-trained otological surgeon. Patients underwent stapedotomy (n = 63) and intact canal wall tympanoplasty (n = 63) with the piezoelectric devi…
