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…
Le tympan du portail central de la cathédrale de Nantes
1998
The tympanum of the central portal of Nantes cathedral. Owing to a reassessment of the available sources on the sculptured decor of the façade of Saint-Pierre et Saint-Paul cathedral in Nantes, it is possible to bring some precisions about the original state of the building. The tympanum of the central portal of this façade did not present, as is usually acknowledged, an original openwork design which was filled up in the 17th century when the organ loft was erected. The analysis of the still existing remnants, as well as the size and nature of the stones used in this portal leads one to think that its present state dates back to the actual construction. Textual pieces of evidence allow the…
Intratympanic treatment with dexamethasone as first-line or salvage therapy in sudden sensorineural hearing loss: Results of a retrospective study
2014
Aim: Sudden sensorineural hearing loss is a condition of emergency in Otolaryngology. Although there is no universally accepted treatment protocol, corticosteroids, intravenous and oral, are the most common treatment The purpose of this study is to evaluate the efficacy of intratympanic administration of dexamethasone as first line therapy, or as a rescue therapy after treatment with systemic steroids in patients not responders. Methods: The population, consisting of 85 patients referred to our unit from January 2010 to December 2013, was divided into two groups according to the treatment protocol performed. We also analyzed possible variables that may affect the response to treatment such …
Fat plug myringoplasty: Analysis of a safe procedure for small tympanic perforations
2015
Objective: Assessment of value of fat plug myringoplasty as office-based procedure in small tympanic membrane perforations. Material and Methods: Prospective study of consecutive patients undergoing fat plug myringoplasty under local anesthesia. Minimum follow-up considered was 6 months, which included several microscopic examinations. All data were recorded and analyzed statistically. Results: 33 patients matched the inclusion criteria; the mean perforation size was 2.8 mm. No change in PTA was noted after surgery in the whole series. Recurrence of perforation was detected in 7 cases (21%), which was statistically related with the cause of perforation rather than location or size (p-value …
FOLLOW-UP AFTER PEDIATRIC MYRINGOPLASTY: OUTCOME AT 5 YEARS
2014
Aim. The aim of this paper was to evaluate anatomical and functional outcomes 5 years after myringoplasty in children affected by perforated eardrum. To analyze the main differences in the frequency of postoperative complications between patients under and over 9 years of age. Methods. One hundred and thirty-two children, aged from 4 to 15 years, who underwent myringoplasty with or without mastoidectomy, were followed for a five-year period after surgery. The cohort was divided in two groups: children from 4 to 9 years old (G1) and patients older than 9 years (G2); all subjects underwent a pre- and post-operatively clinical exam and were evaluated through audiometry and impedenzometry. Aden…
Otite media atelettasica, adesiva, timpanosclerotica: update medico e chirurgico
2011
Otitis media secretive is one of the most common ear diseases characterized by frequent sequelae and complications; in particular the authors describe middle ear atelectasis with pocket retraction of tympanic membrane, pocket retraction limited to pars tensa or to pars flaccida, adhesive otitis media, partial or total myringosclerosis and tympanosclerosis. For each disease the Authors comment the best surgical approaches to preserve and restore conductive hearing loss. As for middle ear atelectasis, adhesive otitis media, myringosclerosis and partial tympanosclerosis it was evidenced a significant hearing gain while in total tympanosclerosis there was an initial hearing improvement in a sho…
Augmented reality based middle and inner ear surgical procedures
2020
Otologic procedures involve manipulation of small, delicate and complex structures in the temporal bone anatomy which are in close proxmity of critical nerves and blood vessels. Augmented reality (AR) can highly benefit the otological domain by providing supplementary anatomical and navigational information unified on a single display. However, despite being composed of mainly rigid bony structures, the awareness and acceptance of possibilities of AR systems in otology is fairly low. This project aims at developing video-based AR solutions for middle and inner ear surgical procedures.We propose two applications of AR in this regard. In the first application, information about middle ear cle…
Augmented Reality in minimally invasive otologic surgery and transmodiolar cochlear implantation
2021
Optimal exposure is necessary for minimally invasive otologic surgery. Augmented reality allows to enrich the real environment by adding data without replacing it by a virtual environment and to view this information on a single screen by combining the vision of the operating field and the imaging. This technique is very little described in otology in the literature. This project aims to develop augmented reality solutions for otological surgeries and transmodiolar implantation. To prepare this augmented reality project, we studied the visualization of the middle ear by a virtual endoscope based on preoperative high resolution CT-scans. Then, we worked on the application of augmented realit…
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, …
