Circumferential Subannular Tympanoplasty: Panacea for revision tympanoplasty.

OBJECTIVE: To evaluate the role of Circumferential Subannular Tympanoplasty [CST] in cases of Revision tympanoplasty. METHODS: A retrospective statistical analysis of data of 81 patients who underwent revision tympanoplasty with CST technique [essentially Type I tympanoplasty] was done. An intact graft at the end of 6 months was regarded as a surgical success. RESULTS: Overall, we recorded a surgical success rate of 97.5% [79 out of 81 cases] with a 100% surgical success for anterior perforations. There was no impact of size or site of perforation on the outcomes of revision tympanoplasty by this technique. In addition, a statistically significant hearing improvement was recorded in the study. The mean pre-operative and post-operative ABG were 33.85 dB and 18.87 dB respectively. The mean ABG closure was 14.89 dB. The value of "p" by Chi square test was found to <.05. CONCLUSION: CST is an excellent technique for revision tympanoplasty and seems to address the shortcomings of conventional onlay and inlay techniques.

Subjective Visual Vertical Testing in Patients With Chronic Suppurative Otitis Media.

OBJECTIVE: To analyze the results of the subjective visual vertical test using the "bucket method" in patients with chronic suppurative otitis media (CSOM). STUDY DESIGN: Cross-sectional, controlled study. SETTING: Outpatient otology clinic in a tertiary care hospital. SUBJECTS AND METHODS: Patients had CSOM, defined as the presence of chronic infection or inflammation of the middle ear cleft, associated with a perforation of the tympanic membrane, frequent or intractable middle ear suppuration, with or without cholesteatoma. Controls were selected using a nonprobability, purposive sampling method. We excluded patients with neurologic or metabolic diseases, cognitive deficits, otosclerosis, vestibular migraine, Ménière's disease, past use of ototoxic medication, or head and neck cancer. The volunteers were subjected to the subjective visual vertical test using the "bucket method." The results obtained in our study and control groups were analyzed using nonparametric tests. RESULTS: Our study comprised 51 patients with CSOM and 50 controls. In the CSOM group, we observed that 72.5% of the patients had vestibular symptoms in the past year, and 70.5% had abnormalities identified in at least 1 vestibular function test. The subjective visual vertical test revealed that patients with CSOM (with and without cholesteatoma) had significantly higher deviations of the true vertical as compared with controls (CSOM, 3.66°; controls, 0.76°; P < .001). CONCLUSION: Our results revealed that CSOM was associated with high rates of vestibular symptoms, abnormal vestibular function tests, and abnormal subjective vertical visual results.

Analysis on the correlation between Eustachian tube function and outcomes of type I tympanoplasty for chronic suppurative otitis media.

Background: The potential influence of Eustachian tube dysfunction (ETD) on the efficacy of tympanoplasty is controversial.Objective: This study aims to investigate the correlation between Eustachian tube function (ETF) and outcomes of type I tympanoplasty for chronic suppurative otitis media (CSOM).Materials and Methods: 53 patients with CSOM and receiving type I tympanoplasty were divided into a dysfunction group (Eustachian tube score; ETS ≤ 5points) and a normal group (ETS > 5 points) according to their preoperative ETS. During the one-year follow-up, the ETS, hearing results, and eardrum condition of the patients were recorded and analyzed.Results: The ETS improved significantly from 2.57 (±1.73SD) to 4.68 (±2.00SD), while the mean air-bone gap (ABG) decreased significantly from 20.94 (±9.04SD) dB to 16.43 (±9.06SD) dB in the dysfunction group (p < .05). The postoperative ABG showed no significant difference in the two groups. The healing rate of the tympanic membrane was 96.43% in the dysfunction group, and 100% in the normal group.Conclusions and significance: The ETF was significantly improved after type I tympanoplasty for CSOM combined with ETD, and the postoperative efficacy was not adversely affected. The ETD may not influence the outcomes of type I tympanoplasty for CSOM.

Cochlear Implantation in Patients with Chronic Suppurative Otitis Media: Surgical Outcomes and a Management Algorithm.

BACKGROUND: Chronic suppurative otitis media (CSOM) was considered as a contraindication of cochlear implantation (CI) in the past. Recently, various surgical options have been adopted for CI in CSOM patients with showing a low complication rate. OBJECTIVES: To evaluate surgical outcomes of CI in patients with CSOM and to propose a management algorithm for those patients. METHODS: Thirty-six consecutive patients with CSOM who underwent single stage or staged CI were enrolled. Speech performance, including Categories of Auditory Performance (CAP) test and sentence score, and complications were retrospectively analyzed. RESULTS: The average follow-up was 3.1 years (range 0.5-9.2 years). Postoperative median CAP and sentence scores were 6 and 78%, respectively. Three (8.3%) of the 36 patients had postoperative complications. One experienced breakdown of the ear canal closure. Recurrence of the pars tensa retraction was observed in another patient with adhesive otitis media who underwent CI and cartilage tympanoplasty as a single stage operation. Electrode extrusion occurred in another patient who underwent staged CI with maintenance of a previous open cavity. Subtotal petrosectomy and cavity obliteration were used to manage the latter 2 complications. All implant patients with good mastoid pneumatization exhibited no complications. There were no significant differences in postoperative speech performance and complication rates between single stage CI and staged CI. Based on these current findings, a management algorithm was proposed according to type of CSOM, presence of open cavity, and mastoid pneumatization. CONCLUSIONS: Patients with CSOM show good postoperative speech performance after CI. Proper surgical options according to type of CSOM, presence of open cavity, and mastoid pneumatization may help in reducing complications.

Evaluation of Type III Tympanoplasty Using Cartilage Ossiculoplasty in Cholesteatoma Ear Surgery.

This prospective observational study evaluates the role of tympanoplasty type III in cholesteatoma ear disease during same sitting with mastoid surgery using cartilage ossiculoplasty. Forty patients of chronic suppurative otitis media-cholesteatoma disease were recruited in the study. All the patients had extensive cholesteatoma and underwent canal wall down mastoid surgery. Tympanoplasty type III, that is, stapes columella, minor columella, or major columella, was done in each case along with mastoid surgery depending upon the remnant ossicular status. Conchal cartilage graft was used for ossiculoplasty along with temporalis fascia graft. Hearing and graft uptake results were evaluated at the end of 6 months postoperatively. Of the 40 cases, 3 cases failed tympanoplasty. In the remaining 37 cases, a statistically significant hearing improvement (air-bone gap of 33 dB) was observed postoperatively. Seven cases underwent stapes columella, 13 cases underwent minor columella, and 17 cases underwent major columella tympanoplasty type III. Although a hearing improvement was recorded in all these subgroups, a statistically significant hearing gain was present only in tympanoplasty type III minor columella cases thereby underlying the importance of intact stapes. However, it is difficult to discern the type of tympanoplasty type III that the patient would undergo prior to the ear surgery.

Postoperative change in wideband absorbance after tympanoplasty in chronic suppurative otitis media.

OBJECTIVE: To identify the wideband absorbance (WBA) of reconstructed TM comparing with perforated and normal TM, and to investigate the efficacy of WBA to predict postoperative hearing outcome. METHODS: Ninety-eight adults (128 ears) with normal TM and 40 patients (40 ears) who were diagnosed with chronic suppurative otitis media (CSOM) and underwent tympanoplasty type 1 were enrolled. Pure tone audiometry and WBA were measured before and 6 and 12 months after surgery. Finally, only 29 patients in CSOM group completed all the tests. RESULTS: Significant differences in WBA were observed between normal ears, CSOM, and reconstructed ears at middle to high frequencies. During follow-up, absorbance decreased at low frequencies and increased at middle to high. Significant positive correlation at low to middle frequency was observed between change in air-bone gaps (ABG) and absorbance at corresponding frequencies. CONCLUSION: WBA in patients with CSOM was significantly different from normal TM, and a significant change in WBA was observed after tympanoplasty with improvement of ABG. WBA may be a useful tool for monitoring the postoperative change in absorbance of sound energy in the middle ear.

Audiological function in a group of adults following myringoplasty: an exploratory study in South Africa.

INTRODUCTION: Chronic suppurative otitis media is a global middle ear disease with quality of life as economic implications, which are worse felt in low and middle income (LAMI) countries; thus the need for myringoplasty. This study aimed to explore audiological function in a group of adults following myringoplasty in South Africa, with an exploration of the possible influence of factors such as HIV/AIDS and type of surgical technique on hearing outcomes. METHODS: Within a retrospective chart review research design, 41 participant files for a six-year period from two academic hospitals in Johannesburg, South Africa, were reviewed. Data were analysed using both descriptive and inferential statistics. RESULTS: Participant files comprised of 16 males and 25 females between 18-63 years. Findings revealed that clinically, overall hearing improved post-operatively, as indicated by improved tympanometry findings, pure tone air-conduction and speech reception thresholds. Descriptively, the predictors of improved hearing outcomes post-operatively appeared to be HIV negative status and butterfly cartilage inlay surgery as a surgical technique adopted. Although clinically, hearing outcomes improved post-operatively at all air-conduction frequencies tested; these clinical improvements were only statistically significant at specific frequencies. CONCLUSION: Current findings provide useful initial evidence on the benefits of myringoplasty from the South African context; particularly because of the HIV/AIDS prevalence and its potential influence on middle ear disease and its management. Prospective efficacy studies with bigger sample sizes are recommended, with early identification strategies for middle ear disease to reduce the need for myringoplasty seriously considered bearing in mind the resource constraints.

Risk factors of sensorineural hearing loss in patients with unilateral safe chronic suppurative otitis media.

PURPOSE: Chronic suppurative otitis media (CSOM) is the major cause of hearing impairment, especially conductive hearing loss. Few patients also had sensorineural component, the sensorineural hearing loss (SNHL) in CSOM is controversial, especially for safe mucosal type. This study aims to assess the relationship between the frequency of SNHL development in patients with safe mucosal CSOM and its relation to patient's age, sex, duration of disease, size of perforation and different audiological findings. MATERIAL AND METHODS: This is a prospective study conducted from June 2016 to June 2017 in a tertiary referral hospital. 200 patients with unilateral mucosal type of CSOM with normal contralateral ear were included in the study. The diseased ears were taken as study ears and normal ears as control ears in all patients. Detailed otologic history, clinical and audiometric findings were recorded and analyzed. Results were statistically compared in all patients for both study and control ears using different parameters. RESULTS: Twenty patients had an average bone conduction threshold of all frequencies above 25dB, which implies SNHL (10%). The incidence of SNHL was statistically significant at higher speech frequencies. The incidence increased with the presence of Diabetes Mellitus, smoking, duration of disease, presence of active discharge and the increase in size of perforation. However, it is not age dependent and there was no difference between males and females. CONCLUSION: Safe mucosal CSOM can cause SNHL with multiple predisposing factors.

Correlation between sensorineural hearing loss and chronic otorrhea.

Many studies have attempted to correlate chronic otorrhea in children and in adults with the sensorineural hearing loss in the affected ear, with contradictory results. This loss might be the result of the likely toxicity of the bacteria involved, effects of inflammatory cytokines, or constant use of ototoxic antibiotics. All studies evaluated to date compared the affected ear with the normal contralateral ear. From the digitized archive of otologic surgery files of the Department of Otorhinolaryngology at Santa Casa de São Paulo School of Medical Sciences, the ears of patients with chronic otorrhea were evaluated visually and compared with the normal contralateral ears. Ears with otorrhea were also compared with ears of other patients with dry tympanic perforation. Ears with suppuration were evaluated for cholesteatoma. The duration of otorrhea was considered. The sensorineural hearing threshold was evaluated for the frequencies of 500, 1,000, 2,000, and 4,000 Hz. A total of 98 patients with chronic otorrhea and 60 with dry tympanic membrane perforation were evaluated. A correlation between sensorineural hearing loss and chronic otorrhea was observed when compared with both contralateral normal ears and dry perforated ears of other patients. No relationship between hearing loss and the duration of suppuration or cholesteatoma was found. Sensorineural hearing loss occurs in ears with chronic otorrhea. The duration of otorrhea and the etiology of suppuration did not influence the hearing loss.

Hearing Status after Radical Mastoidectomy without Tympanoplasty.

OBJECTIVE: To find out the impairment of hearing associated with radical mastoidectomy by measuring the quantitative difference in the functional hearing level before and after radical mastoidectomy operation without tympanoplasty. STUDY DESIGN: Cross-sectional comparative study. PLACE AND DURATION OF STUDY: Department of Otorhinolaryngology and Head Neck Surgery, Bahawal Victoria Hospital, Bahawalpur and PNS Shifa Hospital, Karachi, from November 2009 to January 2013. METHODOLOGY: Eighty-five patients, diagnosed clinically as chronic suppurative otitis media with extensive cholesteatoma having history of ear discharge and hearing impairment for more than 6 weeks duration and requiring radical mastoidectomy for treatment, were included in this study. Pure tone audiogram was done before and after radical mastoidectomy. Hearing impairment was compared in each patient before and after the operation. RESULTS: Among the 85 patients, 54 (63.5%) were males and 31 (36.5%) were females, with the age ranged between 18 to 63 years, mean age being 42.31 4.8 years. The mean increase in hearing loss after radical mastoidectomy in air conduction was 7.19 dB, bone conduction was 4.16 dB, and air-bone gap was 3.75 dB (0.001). The ear became dry and safe in 82 patients (96.5%) out of a total of 85, and only 3 patients required revision surgery at a second stage. CONCLUSION: Radical mastoidectomy has a least negligible effect on hearing status and one should not limit this technique due to the concern of aggravated hearing in patients with extensive cholesteatoma at the cost of dry and safe ears, which should be of prime importance.

[The specific features of the clinical course of acute suppurative otitis media of viral and mixed viral-bacterial etiology in the children of the preschool age]. / Klinicheskie osobennosti techeniia ostrogo srednego gnoinogo otita virusnoi i virusno-bakterial'noi étiologii u detei doshkol'nogo vozrasta.

The objective of the present study was to elucidate the spectrum of the pathogenic agents responsible for the development of acute suppurative otitis media in the children of the preschool age and to reveal the specific clinical features of this disease depending on its etiological factors. The study involved 138 patients (186 ears) of either sex at the age from 1 year to 84 months who presented with acute suppurative otitis media. The following methods were employed for the purpose of the study: analysis of the patients' complaints and the past medical histories, examination of the ENT organs, microbiological (bacteriological and virological) studies of secretion from the tympanic cavity, diagnostic endoscopy of the nasal cavity and nasopharynx, laboratory investigations. The study allowed to reveal the characteristic clinical manifestations of the pathology of interest depending on its etiology.

Progression of changes in the sensorial elements of the cochlear and peripheral vestibular systems: The otitis media continuum.

Our study aimed to evaluate pathologic changes in the cochlear (inner and outer hair cells and stria vascularis) and vestibular (vestibular hair cells, dark, and transitional cells) sensorial elements in temporal bones from donors who had otitis media. We studied 40 temporal bones from such donors, which were categorized in serous otitis media (SOM), serous-purulent otitis media (SPOM), mucoid/mucoid-purulent otitis media (MOM/MPOM), and chronic otitis media (COM); control group comprised 10 nondiseased temporal bones. We found significant loss of inner and outer cochlear hair cells in the basal turn of the SPOM, MOM/MPOM and COM groups; significant loss of vestibular hair cells was observed in the MOM/MPOM and COM groups. All otitis media groups had smaller mean area of the stria vascularis in the basal turn of the cochlea when compared to controls. In conclusion, our study demonstrated more severe pathologic changes in the later stages of the continuum of otitis media (MOM/MPOM and COM). Those changes seem to progress from the basal turn of the cochlea (stria vascularis, then inner and outer hair cells) to the middle turn of the cochlea and to the saccule and utricle in the MOM/MPOM and COM stages.

Tubotympanic system functioning.

The Eustachian (auditory) tube and tympanomastoid cavities form an anatomic and functional whole that cannot easily be divided, and is therefore known as the "tubotympanic system". The system has been the focus of several studies, with complex and sometimes contradictory results, making an overview of its functioning difficult to obtain. The objective of the present article is to review the current state of knowledge, as an indispensable preliminary to understanding tubotympanic system dysfunction, and notably the development of chronic otitis. The system as a whole is covered by mucosa, which provides continuity, although with certain particularities from one area to another, and plays a primordial role. Thus, under physiological conditions, gas diffusion across the tympanomastoid mucosa largely ensures the equilibrium of pressure between the middle ear and outside environment, the tube orifice being very little involved. Under large rapid change in atmospheric pressure, the aeration function of the Eustachian tube comes into play, governed by a reflex mechanism. The system also has other functions that are essential to good middle-ear functioning: protection against nasopharyngeal secretions and pathogens and against certain physiological noises; middle-ear cavity clearance by mucociliary transport of pathogens, partly related to submucosal gland secretion; and immune defense.

Clinical, functional, and surgical findings in chronic bilateral otitis media with effusion in childhood.

We conducted a prospective, observational study over a 3-year period to compare the clinical, functional, and surgical findings in children with chronic bilateral otitis media with effusion who underwent one of three different types of treatment. Our study population was made up of 150 patients-79 boys and 71 girls aged 24 to 84 months-who were randomly assigned to one of the three treatment groups of 50 patients each. One group was treated with myringotomy, tympanostomy tube insertion, and adenoidectomy (T+A group); another with a combination of physical conservative treatment and adenoidectomy (P+A group); and the third with physical conservative treatment alone (P-only group). Hearing levels and tympanogram trends were evaluated during a follow-up of 12 months. In the T+A group, we noted a stable normalization of hearing in 95 of the 100 ears. Treatment with the P+A combination resulted in an improvement of hearing in 79 ears, but the improvement was maintained in only 27 ears during 12 months of follow-up. In the group with the P-only regimen, an amelioration of hearing was registered in 76 ears, but it was unstable in all cases. A type A tympanogram was maintained during the follow-up period for 2 ears in the P+A group and for 4 ears in the P-only group. Myringotomy with a detailed examination of the tympanic cavity in all ears with prolonged abnormal audiologic results revealed that types C and B tympanograms, which were found in most ears in the P+A and P-only groups, corresponded to middle ear chronic inflammatory changes (retraction pockets, granulations, adhesions, etc.) Based on our findings, we conclude that the use of a physical conservative treatment with or without an adenoidectomy does not prevent the development of chronic adhesive and purulent otitis media.

Preoperative Predictors in Chronic Suppurative Otitis Media for Ossicular Chain Discontinuity: A Cross-Sectional Study.

OBJECTIVE: Ossicular discontinuity may result from chronic suppurative otitis media and is usually detected intraoperatively. Our objective is to determine whether a preoperative audiogram can preoperatively predict the presence or absence of ossicular discontinuity. METHODS: A cross-sectional study was prospectively run on our patients, aged 12-75 years, ultimately operated on for chronic suppurative otitis media. Preoperative audiograms were analyzed to measure frequency-specific air-bone gap (ABG) cutoff values. Intraoperatively, ossicular chain integrity was carefully checked. Logistic regression analysis was done to obtain a predictive model. RESULTS: A total of 270 patients (306 ears) were included. Frequency-specific ABG cutoff values can predict ossicular discontinuity, namely: high ABGs at 1,000 Hz (>27.5 dB) and 2,000 Hz (>17.5 dB) are the most reliable variables associated with ossicular discontinuity. CONCLUSION: Preoperative audiograms can predict the presence of ossicular discontinuity in chronic suppurative otitis media. Large ABGs at both 1,000 and 2,000 Hz can predict ossicular discontinuity with a great degree of certainty.

[The comparative analysis of the clinical and morphological picture of the various forms of chronic suppurative otitis media].

We present the results of the surgical treatment of 300 patients presenting with chronic suppurative otitis media. The changes in the mucous membrane of the tympanic cavity were revealed in 61% of the patients with mesotympanitis while spreading cholesteatoma occurred in 48% of the cases of «dry¼ perforations. The cholesteatomic process was documented in 64% of the patients with epitympanitis, the remaining patients presented with the pyo-carious process. The efficiency of the surgical intervention on the «dry¼ ear of the patients with the tubotympanic form of chronic suppurative otitis media (CSOM) amounted to 91.4% compared with 85% in the case of the altered mucous membrane of the tympanic cavity, 85.5% and 92.9% in the patients with the pyo-carious and cholesteatomic forms of the tympano-antral lesions, respectively. Residual cholesteatomas were found in 7.8% of the patients suffering from epitympanitis during the three year follow-up period. It is concluded that the results of clinical and morphological observations taken together with intraoperative findings give reason to consider mesotympanitis to be a prognosticallyunfavourable form of chronic suppurative otitis media.

[Efficacy of Dioxidine antimicrobial preparation for the treatment of inflammatory diseases of the external and middle ear].

In this article, the comparative analysis of the clinical efficacy of drugs for local therapy in patients with acute external otitis, acute purulent otitis media and exacerbation of chronic suppurative otitis media is presented. The results of the clinical study, dynamic bacteriological investigation confirmed the high efficacy, safety and good tolerance of dioxidine in treatment of external and middle ear infections.

Otologic evaluation of patients with primary antibody deficiency.

Common variable immunodeficiency (CVID) represents the most frequent primary immunodeficiency, often encountered in the ENT clinical practice. The clinical spectrum of CVID is quite broad, but otitis media are certainly among the most common clinical manifestations. This prospective study enrolled 60 patients (34 males, 26 females) with a previous diagnosis of CVID with the aim of performing an otologic evaluation and a more precision characterization of incidence, diagnosis, and treatment of otitis media in this group of patients. In consideration that Eustachian tube dysfunction (ETD) could be the 'primum movens' of otitis media, we wanted to assess whether a Eustachian tube dysfunction was present in these patients. Besides, we propose a possible diagnostic algorithm of middle ear pathologies to use in all cases of primary antibody deficiency patients. Results of our otologic examination showed that: 5 % of patients had chronic suppurative otitis media, 25 % bilateral otitis media with effusion and 10 % reported unilateral OME with associated contralateral ETD. There was bilateral isolated ETD and unilateral isolated ETD in 5 and 15 % of patients, respectively. All patients with unilateral OME had associated contralateral ETD. Finally, 40 % of patients were bilaterally negative at otoscopic examination and all otologic tests.

Childhood otitis media is associated with dizziness in adulthood: the HUNT cohort study.

The objective of the study was to examine the association between otitis media in childhood and dizziness in adulthood. Longitudinal, population-based cohort study of 21,962 adults (aged 20-59 years, mean 40) who completed a health questionnaire in the Nord-Trøndelag Hearing Loss Study was conducted. At 7, 10 and 13 years of age, the same individuals underwent screening audiometry in a longitudinal school hearing investigation. Children found with hearing loss underwent an ear, nose and throat specialist examination. Adults diagnosed with childhood chronic suppurative otitis media (n = 102) and childhood hearing loss after recurrent acute otitis media (n = 590) were significantly more likely to have increased risk of reported dizziness when compared to adults with normal hearing as children at the school investigation and also a negative history of recurrent otitis media (n = 21,270), p < 0.05. After adjusting for adult age, sex and socio-economic status, the odds ratios were 2.1 [95 % confidence interval (CI): 1.4-3.3] and 1.3 (95 % CI: 1.0-1.5), respectively. This longitudinal cohort study suggests that childhood chronic suppurative otitis media and childhood hearing loss after recurrent acute otitis media are associated with increased risk of dizziness in adulthood. This might reflect a permanent effect of inflammatory mediators or toxins on the vestibular system. The new finding stresses the importance of treatment and prevention of these otitis media conditions.
