A systematic review of otologic injuries sustained in civilian terrorist explosions.

PURPOSE: Determine the prevalence of otological symptoms and tympanic membrane perforation, healing rates of tympanic membrane perforation with surgical and conservative management, and hearing function in civilian victims of terrorist explosions. METHODS: A systematic review was conducted with searches on Medline, Embase, EMCare and CINAHL for publications between the 1st January 1945 and 26th May 2023. Studies with quantitative data addressing our aims were included. This review is registered with PROSPERO: CRD42020166768. Among 2611 studies screened, 18 studies comprising prospective and retrospective cohort studies were included. RESULTS: The percentage of eardrums perforated in patients admitted to hospital, under ENT follow up and attending the emergency department is 69.0% (CI 55.5-80.5%), 38.7% (CI 19.0-63.0%, I2 0.715%) and 21.0% (CI 11.9-34.3%, I2 0.718%) respectively. Perforated eardrums heal spontaneously in 62.9% (CI 50.4-73.8%, I2 0.687%) of cases and in 88.8% (CI 75.9-96.3%, I2 0.500%) of cases after surgery. Common symptoms present within one month of bombings are tinnitus 84.7% (CI 70.0-92.9%, I2 0.506%), hearing loss 83.0% (CI 64.5-92.9%, I2 0.505%) and ear fullness 59.7% (CI 13.4-93.4%, I2 0.719). Symptomatic status between one and six months commonly include no symptoms 57.5% (CI 46.0-68.3%), hearing loss 35.4% (CI 21.8-51.8%, I2 0.673%) and tinnitus 15.6% (CI 4.9-40.0%, I2 0.500%). Within one month of bombings, the most common hearing abnormality is sensorineural hearing loss affecting 26.9% (CI 16.9-40.1%, I2 0.689%) of ears 43.5% (CI 33.4-54.2%, I2 0.500) of people. CONCLUSION: Tympanic membrane perforation, subjective hearing loss, tinnitus, ear fullness and sensorineural hearing loss are common sequelae of civilian terrorist explosions.

Prophylactic antibiotics has no benefit for outcome in clean myringoplasty-A register-based cohort study from SwedEar.

OBJECTIVES: To investigate if prophylactic antibiotics (PA) in conjunction with myringoplasty of clean and uninfected ears entails a reduction of postoperative infections within 6 weeks after surgery, and whether it affects the healing rate of the tympanic membrane (TM) at follow-up, 6-24 months after surgery. DESIGN: A retrospective cohort study of prospectively collected data. SETTING: Data extracted from The Swedish Quality Register for Ear Surgery (SwedEar), the years 2013-2019. PARTICIPANTS: All patients in SwedEar with a registered clean conventional myringoplasty (tympanoplasty type I) including a follow-up visit. MAIN OUTCOME MEASURES: The effect of PA use on TM healing rate at follow-up and postoperative infection within 6 weeks of surgery. RESULTS: In the study group (n = 1665) 86.2% had a healed TM at follow-up. There was no significant difference between the groups that had PA administered (87.2%) or not (86.1%). A total of 8.0% had a postoperative infection within 6 weeks. Postoperative infection occurred in 10.2% of the group that received PA (n = 187) compared with 7.7% of the group that did not receive PA. However, this difference was not statistically significant. Postoperative infection within 6 weeks significantly lowered the frequency of healed TMs. CONCLUSION: PA administered during clean conventional myringoplasty does not improve the chance of having a healed TM at follow up, nor decrease the risk of having a postoperative infection within 6 weeks after surgery.

Incidence and Epidemiology of Traumatic Tympanic Membrane Rupture: A National Trauma Data Bank Analysis.

The incidence of traumatic tympanic membrane rupture (TTMR) has increased over recent decades. The association of certain external injury causes and bone fracture patterns with TTMR is anecdotal. It has been suggested that a diagnosis of TTMR may be missed during the acute trauma admission. The authors sought to evaluate the incidence of TTMR according to external injury cause and evaluate the association of skull fracture patterns with TTMR using a national trauma database. A cross-sectional analysis of trauma encounters was conducted using the National Trauma Data Bank (NTDB) from 2008 to 2015. Demographic and injury data were abstracted. Poisson regression was used to determine the incidence rate ratios of tympanic membrane rupture by external injury cause and logistic regression was used to estimate odds ratios (OR) of TTMR by skull fracture type. A total of 8214 patients were identified with TTMR during acute admission. The majority were on average 30 years old, 76% male, 71% White, had a mean Injury Severity Score of 14, and 42% were admitted to level I centers. The incidence rate ratio was only higher in lightning related injuries [5.262; 95% confidence interval (CI): 4.194-6.602] when using those caused by explosives as a reference. Basilar skull (OR: 12.95; 95% CI: 12.095-12.866) and cranial vault (OR: 2.938; 95% CI: 2.647-3.260) fractures were most associated with TTMR. The high incidence TTMR in association with certain external causes of injury and types of skull fractures should drive screening in the acute setting in order to increase detection and reduce morbidity from missed injuries.

Immunological profiles of children with recurrent otitis media with or without spontaneous tympanic membrane perforation and of children with recurrent respiratory infections.

OBJECTIVES: The primary aim of this study was to compare the immunological profiles of children affected by recurrent acute otitis media (rAOM) with and without spontaneous tympanic membrane perforation (STMP). The secondary aim was to compare immunological features of children without parameters outside the normal range and affected by either rAOM or recurrent respiratory tract infections (rRTI). METHODS: In this study, otherwise healthy children (<10 years of age) with rAOM or rRTI were included. Data on perinatal history, vaccination status, presence of risk factors for rAOM or rRTI (including personal or family history of allergy) and number of infectious episodes in the previous 12 months were retrospectively obtained. Furthermore, data on immunological profile (blood cell count, circulating IgA, IgG, IgM and total IgE, IgG subclasses and lymphocyte subpopulations) were collected. The immune profile of children affected by rAOM with and without STMP were compared. Among children with parameters within normal range, we compared the levels of the immunological parameters of children affected by rAOM (with and without STMP) and rRTI. RESULTS: The study involved a total of 751 children: 566 (75.3%) with rAOM and 185 (24.7%) with rRTI. Among the 566 children with rAOM, 39.7% had uncomplicated rAOM and 60.3% had rAOM with STMP. The mean age of the study population was 34.9 (SD 20.5) months. The frequency of children with parameters outside the normal range was similar among children with rAOM with (4.9%) and without STMP (6.1%). Among subjects without parameters outside the normal range, children with uncomplicated rAOM had significantly lower serum IgG, lymphocyte CD8+ and CD19+ and significantly higher IgG2 levels than children affected by rAOM with STMP. Finally, children with rAOM had lower levels of IgA, IgM and IgG2 and higher levels of IgG, lymphocyte CD19+ and CD16/56+ compared to children with rRTI. CONCLUSIONS: A low (<6.5%) percentage of children with rAOM with or without STMP present parameters outside the normal range. Among subjects without parameters outside the normal range, children with uncomplicated rAOM have a different immune profile as compared to those with STMP and rRTI. New prospective studies are needed to further explore the immune features of children affected by rAOM with and without STMP.

Clinical characteristics of atelectatic eardrums and adhesive otitis media in children.

OBJECTIVES: Atelectatic eardrum and adhesive otitis media in children are related to persistent otitis media with effusion (OME) and eustachian tube dysfunction in infancy. However, the pathogenesis of these diseases is not fully understood, and some cases even progress to pars tensa cholesteatoma. This study analyzed the clinical characteristics of children with atelectatic eardrum and adhesive otitis media to clarify associated causes of and risk factors for progression of these middle ear pathologies in children. PATIENTS AND METHODS: This retroactive study included 38 ears of 31 children with atelectatic eardrums (atelectasis group), and 19 ears of 17 children with adhesive otitis media (adhesive OM group). Thirty-two contralateral non-cholesteatoma ears of 32 children with congenital cholesteatoma were also examined as a control group. Participants were aged 15 or younger. Life history (obtained via questionnaire), associated diseases, hearing acuity, aeration and development of the temporal bone were investigated. RESULTS: All children in the atelectasis and adhesive OM groups had a history of recurrent acute otitis media (rAOM) and/or OME. The prevalence of perennial allergic rhinitis was 18 cases (58%) in the atelectasis group and 16 cases (94%) in the adhesive OM group. The prevalence of perennial allergic rhinitis was significantly higher in the adhesive OM group compared to the control group (P < 0.01). The development of mastoid air cells, categorized by MC classification, showed MC0 + MC1 (poor pneumatization) in 19 ears (50.0%) with atelectatic eardrums and 12 ears (63.2%) with adhesive OM. Poor pneumatized mastoid was more frequently observed in the ears of the atelectasis and adhesive OM groups compared to the control group (P < 0.01). No significant difference was found in regards to aeration of the middle ear between the two groups; however, aeration was significantly poorer in both groups compared to the control group (P < 0.01). Three characteristics were analyzed using multivariate logistic regression: perennial allergic rhinitis (odds ratio [OR] 4.319, P = 0.013), poor mastoid pneumatization (OR 8.457, P = 0.012), and pars flaccida retraction pocket (OR 20.897, P = 0.006). These characteristics were shown to be significant risk factors for atelectatic eardrums and adhesive OM. In addition, the predisposition to perennial allergic rhinitis was shown to be the most important factor in the progression from atelectatic eardrum to adhesive otitis media (OR 16.615, P = 0.012). CONCLUSION: Children with perennial allergic rhinitis, poor development of mastoid air cells, poor aeration of the temporal bone, and with pars flaccida retraction pocket were at an increased risk of developing an atelectatic eardrum and adhesive OM. In particular, perennial allergic rhinitis was shown to be a significant risk factor in the progression from atelectatic eardrum to adhesive otitis media. Allergic inflammation may affect not only the nasal passages but also the eustachian tube, resulting in persistent middle ear dysfunction. Therefore, children with rAOM/OME who have these risk factors should be carefully monitored and treat over time in effort to prevent progression of pathology.

Tympanic Membrane Perforation among Patients Presenting to Department of Otorhinolaryngology of a Tertiary Care Hospital: A Descriptive Cross-sectional Study.

Introduction: Intact tympanic membrane acts as a partition between the external ear and middle ear. Tympanic membrane perforation is one of the commonest causes of conductive hearing loss. Perforation size is the most important determination of hearing loss. The aim of this study was to find out the prevalence of tympanic membrane perforation among patients presenting to the otorhinolaryngology department of a tertiary care hospital. Methods: A descriptive cross-sectional study was carried out in the Department of Otorhinolaryngology and Head Neck Surgery of a tertiary care hospital from March 2021 to August 2021. Ethical approval was taken from Institutional Review Committee (Reference number: 57112021). Convenience sampling was done and data was collected from 414 patients presenting to the department. Collected data were entered, analyzed in Statistical Package for the Social Sciences version 21.0 and documented for study. Point estimate at 95% Confidence Interval was calculated along with frequency and percentage for binary data. Results: Among 414 patients, tympanic membrane perforation was seen in 100 (24.15%) (20.02-28.27 at 95% Confidence Interval). Among 100 patients with a total of 153 perforated eardrums, mild hearing loss was seen in the majority of the cases. Posterior perforation had a mean hearing loss of 40.41±5.96 dB, central had 39.09±3.13 dB, and anterior had 35.15±5.88 dB. Conclusions: Our study showed the prevalence of tympanic membrane perforation to be high when compared to other similar studies. Hearing loss was observed in all cases; the majority with mild hearing loss. The degree of hearing loss was more in larger and posterior perforation. Keywords: eardrum perforation; hearing loss; otitis media.

Otomycosis in the South of Iran with a High Prevalence of Tympanic Membrane Perforation: A Hospital-Based Study.

INTRODUCTION: Otomycosis is a superficial infection of the external ear caused by fungal pathogens. The genera Aspergillus and Candida are considered the main fungal causative agents, with the predominance of Aspergillus section Nigri. The present study aimed to evaluate the clinical symptoms of patients with otomycosis and predisposing factors and to identify fungal etiological agents using molecular approaches. We also present an overview of published papers on tympanic membrane perforation (TMP) secondary to otomycosis. MATERIALS AND METHODS: An otorhinolaryngologist collected specimens from external ear canals of patients with suspected otomycosis based on the patient's history and clinical examinations. The specimens were collected using sterile swabs. Fungal isolates were confirmed in clinical specimens by direct microscopy and culture methods. Fungal isolates were identified based on molecular approaches. RESULTS: In total, specimens from 211 patients with suspected otomycosis were examined. The presence of fungi was confirmed in about 51% of patients based on fungal elements in direct microscopy and culture-positive fungi. Aspergillus tubingensis was the most commonly isolated species (52.77%), followed by Aspergillus niger (25.92%). Otomycosis due to infection with Candida species was observed in 16% of cases. Of note, in 36.11% of cases, otomycosis was associated with TMP. CONCLUSION: A mycological examination is indispensable for a correct diagnosis in patients with otitis extern. TMP should be considered in patients with otomycosis, as it appears to be relatively common in this population.

Tinnitus after Blast Injury; a Prospective Study in Basrah, Iraq.

BACKGROUND: There is many civilians and soldiers who exposed to explosions in Iraq each month and they need an otolaryngological and audiological assessment. OBJECTIVE: To recognize the possible auditory insults and the recovery period of the acquired damages that may resulted from explosion and help for planning of optimal management strategies of otological manifestations and prevent undesirable consequences. PATIENTS AND METHODS: A prospective, descriptive study included forty-seven patients who were exposed to blast injuries within two weeks came to otolaryngology unit in Basrah Teaching Hospital complaining from otological symptoms from July 2017 tell January 2019. Three periodic assessments were done for each patient. An initial evaluation was done in the 1st visit included a detailed history and examination to evaluate the symptoms and assess the associated non-otological injury. An otological examination were done for all patients in the three visits, included microscopic ear examination, photos for the perforated tympanic membrane were taken to grade the perforations depending on their surface area, Pure tone audiometry and tympanometry. Thirty-eight patients were available to follow up in the 2nd and 3rd visits. RESULTS: All of the 47 patients were young and middle age male, hearing loss and tinnitus were the most presenting symptoms, which improved with time. Hearing impairment mostly in the high frequencies however there was improvement in the subsequent visits. The majority of patients (93.6%) presented with tympanic membrane perforation mostly grade I which usually healed spontaneously. There was a statistically significant associations between the degree of tympanic membrane perforation and associated nonotological injuries and with the explosions if occurred in closed space. CONCLUSION: Blast related otological injury constitute the main cause of morbidity as the ear is the most sensitive organ to explosive blast injury. Hearing loss was the dominant symptoms at presentation mainly in high frequencies, but fortunately most of patients improved with time. Tympanic membrane perforation constituted the mostly seen sign, however spontaneous healing can be expected in the majority of cases.

Does tympanic membrane perforation have a protective effect on the inner ear in blast-injured patients?

BACKGROUND: Blast-induced hearing loss is an acoustic trauma commonly caused by high-energy explosions of improvised explosive devices, and the auditory system may be affected by blast damage. This study aims to evaluate the protective effect of tympanic membrane perforation (TMP) on the inner ear against blast injury. METHODS: In this study, 43 adult patients who had suffered blast injury were divided into three subgroups: intact tympanic membranes in both ears, unilateral TMP, and bilateral TMP. Each patient underwent a comprehensive audiogram, including bone conduction, in the audiology department. RESULTS: Evaluation was performed on 43 (100%) males with a mean age of 31.44±8.01 years (range, 18-52 years). When the type of hearing loss was evaluated separately for each ear, sensorineural hearing loss (SNHL) was observed in 31 (36%), high-frequency SNHL in 26 (30.2%), conductive hearing loss in eight (9.3%), and mixed type hearing loss in 21 (24.4%) ears. TMP was detected in 21 (48.8%) of 43 blast-injured patients, on the right side in four (9.3%) patients, on the left side in seven (16.3%), and bilateral in 10 (23.3%). When the type of acoustic trauma was evaluated, 15 (34.9%) patients were observed to have suffered from the explosion of an IED, 12 (30.2%) from weapon explosion, six (14%) were a vehicle bomb explosion, three (7%) were projectile missile explosion, three (7%) were mortar explosion, two (4.7%) were mine explosion, and two (4.7%) were exposed to the explosion in an armored vehicle (Table 1). CONCLUSION: No significant difference was observed in the majority of the frequencies whether the tympanic membrane was perforated or not in the blast-injured patients and it was concluded that tympanic membrane perforation caused by blast injury had no protective effect on the inner ear.

Risk stratification in endoscopic type I. tympanoplasty.

PURPOSE: Several risk factors were studied in endoscopic type I. tympanoplasty, however, an easy-to-use risk stratification model is still missing. METHODS: Retrospective chart review, focusing on individual risk factors and middle ear risk index (MERI). Patients who underwent endoscopic type I. tympanoplasty were included. RESULTS: Closed tympanic cavity was succesfully created in 88.1% of the 42 cases, the overall 21,5 dB air-bone gap (ABG) was reduced by 9,8 dB. The average MERI score of the patients was 2.1 ± 1.5. 78.6% of the patients were categorised into the mild, while 21.4% into the moderate risk group. The perforation was considered small in 81.0% of the cases, while large in 19.0%. The size of the perforation and the preoperative ABG, but not the MERI status were the only single predictors of success. Using a risk stratification model that is based on the size of the perforation, the preoperative ABG and MERI status, patients could be referred into two distinct groups of risk: the majority expecting excellent outcomes with maximum one risk factor present, and patients with deteriorated rate of success when having two or three risk factors. CONCLUSIONS: Endoscopic type I. tympanoplasty with underlay perichondrium graft can be performed with good chance of success. However, if more than one risk factors are present, the chance of residual perforation becomes great. In addition to the established risk factors, our results point out that despite its strong correlation with perforation size, ABG may have a predictive role.

Nasopharyngeal Microbiota Analysis in Healthy and Otitis-prone Children: Focus on History of Spontaneous Tympanic Membrane Perforation.

BACKGROUND: Recurrent acute otitis media (RAOM) is common in children, and it may result in spontaneous tympanic membrane perforation (STMP), management of which is often challenging. In the upper respiratory tract (URT), resident microorganisms play a pivotal role in otitis media pathogenesis and prevention, as they are able to inhibit the colonization process and otopathogens growth. In particular, Dolosigranulum spp. and Corynebacterium spp. have been associated with respiratory health in several studies. This study aims at comparing both nasopharyngeal microbiota of children with RAOM versus matched controls and nasopharyngeal microbiota of children with a history of RAOM with STMP. METHOD: Nasopharyngeal swabs were collected from 132 children, median age 3.51 (2.13-4.72), including 36 healthy children, 50 with RAOM without STMP, and 46 with RAOM with STMP. Bacterial DNA was subsequently extracted and 16S rRNA gene V3-V4 regions were polymerase chain reaction amplified and sequenced using Illumina MiSeq technology. RESULTS: A higher relative abundance of Dolosigranulum and Corynebacterium genera was detected in the nasopharynx of healthy children (16.5% and 9.3%, respectively) in comparison with RAOM without STMP (8.9% and 4.3%, respectively) and RAOM with STMP (5.2% and 2.8%, respectively). A decreasing pattern in relative abundance of these 2 pivotal genera through disease severity was detected. In all groups, the most abundant genera were Moraxella, Streptococcus and Haemophilus, followed by Dolosigranulum and Corynebacterium. CONCLUSIONS: Our study provides a characterization of the URT microbiota in otitis-prone children with and without history of recurrent STMP, suggesting that the role of Dolosigranulum and Corynebacterium in regulating the healthy URT microbiota should be further studied.

Trends in Use and Timing of Intratympanic Corticosteroid Injections for Sudden Sensorineural Hearing Loss.

OBJECTIVE: Oral corticosteroids are treatment mainstays for idiopathic sudden sensorineural hearing loss (SSNHL). Recent studies suggest that intratympanic (IT) steroid injections may be effective as an alternate or adjunctive therapy. We sought to investigate nationwide trends in treatment patterns for SSNHL. STUDY DESIGN: Retrospective cross-sectional study. SETTING: A large nationwide health care claims database spanning 2007 to 2016. METHODS: Patients with SSNHL were identified from the IBM Watson Health MarketScan Database. Multivariable logistic, linear, and Cox regression were used for demographic- and comorbidity-adjusted analyses. RESULTS: Overall, 19,670 patients were included. Between 2007 and 2016, use of oral corticosteroids alone decreased (83.6% to 64.6%, P < .001), while use of IT corticosteroids alone and combination IT-oral corticosteroids increased (IT only, 7.9% to 15.1%, P = .002; IT-oral, 8.5% to 20.4%, P < .001). During the study period, time to treatment initiation decreased for both administration modalities, though more dramatically for IT corticosteroids (IT, 124.0 to 10.6 days, P < .001; oral, 42.6 to 12.7 days, P < .001). In patients receiving both IT and oral corticosteroids, concurrent first-line use increased (25.2% to 52.8%, P < .001). Repeat injections have also become more common but may raise risk of persistent tympanic membrane perforations (vs no injection; hazard ratio [first injection] = 7.95, 95% CI = 5.54-11.42; hazard ratio [fifth or higher injection] = 17.47, 95% CI = 6.93-44.05). CONCLUSION: SSNHL management increasingly involves early IT steroids as an alternative or adjunctive option to oral steroids. Use of repeat IT corticosteroid injections has also increased but may raise risk of persistent tympanic membrane perforations and subsequent tympanoplasty. Future decision analysis and cost-effectiveness studies are necessary to identify an optimal care pattern for SSNHL.

Otomycosis With Tympanic Membrane Perforation: A Review of the Literature.

OBJECTIVE: The purpose of the present study was to assess the rate of tympanic membrane perforation in patients with otomycosis and to discuss the literature regarding the difficulties in managing this condition. DATA SOURCES: Literature review from 1999 to 2019, Web of Science, PubMed, and Medline. STUDY SELECTION: We searched for eligible articles concerning the clinical entity of tympanic membrane perforation secondary to otomycosis. Case series and clinical trials were the types of articles included for this review. DATA EXTRACTION: All the articles described in the study selection were used for this review. DATA SYNTHESIS: Statistical techniques were not used. CONCLUSION: Based on the available literature, it seems that tympanic membrane perforation secondary to otomycosis is not uncommon. The presence of this complication is associated with 2 problems: Antimycotic solutions are irritant to middle ear and may be ototoxic to the cochlea. Although most cases of fungus caused tympanic membrane (TM) perforation resolve with proper medical treatment, in a few patients a tympanoplasty may be required.

A retrospective review of Paparella Type 1 tympanostomy tubes.

OBJECTIVE: This study aims to provide data on ear tube extrusion and complication rates for patients who have Paparella Type 1 tympanostomy tube (TT) placement. METHODS: Retrospective chart review of patients 6 months to 12 years old who underwent insertion of Paparella Type 1 TT by a single surgeon. RESULTS: Of 197 tubes evaluated, 3% were plugged between 1 and 3 months after surgery. Of the 144 tubes evaluated long-term, all tubes extruded within 4 years. There were no tympanic membrane perforations. CONCLUSIONS: This chart review showed expected rate of initial ear tube plugging. The rate of tympanic membrane perforation was lower than expected.

Fetoplacental ratios in stillbirths and second trimester miscarriages.

An abnormal fetoplacental (F/P) ratio is a risk factor for poor pregnancy outcomes including fetal death, but studies of F/P ratio among stillbirths are limited. In the Wisconsin Stillbirth Service Program cohort of second and third trimester fetal deaths, 1,022 were at ≥24 weeks with data on fetal and placental weight. Comparison with data for viable infants of the same gestational ages (GAs) showed that the F/P ratio increases more rapidly with GA for stillbirths than for viable infants. While placentas of stillborn infants are small at all GA, weights of deceased fetuses are lowest early in the second trimester, becoming nearly normal by term. Excess high F/P ratios are noted at all GAs, increasing toward term, while low ratios are frequent at early gestation but rare near term. Analysis by cause of death shows that F/P ratios are markedly elevated for placental and maternal causes (about 50% above the 90th centile), somewhat elevated for cord accidents, non-hydropic fetal, and unknown causes (about 1/3 above the 90th centile), and variable with 40% below the 10th centile for hydropic stillbirths. Across all causes and GAs, placental weights are more abnormal than fetal weights, suggesting that diminished placental function may contribute to fetal demise even when non-placental causes (e.g., premature membrane rupture, cord accidents, and chromosomal disorders) are identified. About half of all stillbirths have abnormal F/P ratios, suggesting that improvements in prenatal assessment of placental size and function might aid in identifying pregnancies at risk for demise; unfortunately, therapeutic options for ongoing pregnancies with diminished placental function remain limited.

Factors affecting persistent tympanic membrane perforation after tympanostomy tube removal in children.

OBJECTIVES: Evaluate and compare the rates of persistent tympanic membrane (TM) perforations between short-term vs long-term tympanostomy tubes. In addition, to determine which demographic, anatomical, and physical factors affect ear drum healing after tympanostomy tube (TT) removal and simultaneous paper patch myringoplasty (PPM) in children. STUDY DESIGN: Retrospective chart review. METHODS: Charts were reviewed from the Women and Children's of Buffalo hospital and our pediatric otolaryngology practice electronic medical record. Data was retrieved from patients less than 18 years old who underwent surgical removal of a TT and concomitant PPM between January 2005 and January 2017. RESULTS: 343 ear drums were studied that underwent tympanostomy tube removal and paper patch myringoplasty. 45/343 (13%) of ears had a persistent perforation after PPM. The rate of persistent perforation with short-term tubes and long-term tubes was significantly different (6.6% and 20% respectively). Patient characteristics significantly associated with persistent perforations were: age at time of tube removal and number of tubes that patient received. Ear drum characteristics that significantly impacted persistent perforation included: size of ear drum perforation, and presence of tympanosclerosis. Length of intubation, ear drum atrophy, retraction, granulation tissue, middle ear effusion and thickened ear drum were not found to be significant factors. CONCLUSION: Overall, we found an 87% perforation closure rate after surgical removal of the TT and PPM. Persistent perforations occurred significantly more often in patients with long-term tubes than short term tubes. Our data also suggests that several patient and ear drum characteristics may be important factors that contribute to persistent perforation after tympanostomy tube placement and removal.

Determinants influencing success rates of myringoplasty in daily practice: a retrospective analysis.

OBJECTIVES: The aim of this study was to determine influencing factors on tympanic membrane closure and their consequence on absolute risks of closure and hearing improvement in myringoplasties. DESIGN: Retrospective cohort. SETTING: Medium-sized medical centrum. PARTICIPANTS: 195 patients were analysed who underwent a myringoplasty between January 2015 and February 2017 at the Jeroen Bosch Hospital in The Netherlands. MAIN OUTCOME MEASURES: Patient-related data, descriptions of the tympanic defect, surgical data, and the most important follow-up data were collected. Primary outcome is successful closure of the tympanic membrane and the secondary outcome is the amount of air-bone gap improvement after surgery. RESULTS: The overall success rate of the myringoplasty graft was 74.9%. If cartilage and butterfly graft were used, higher success rates of 85.4% and 85.5% were achieved compared to temporalis fascia (61.3%). Success rate of the operation was dependent of the skills of the surgeon. Chances of success are 91.9% if the operation is performed by an experienced surgeon using cartilage and 66.7% if a less experienced surgeon uses fascia. If a postoperative complication occurs or when silastic sheets are used, this might have a negative effect on the success of the operation. The mean ABG improved 10.10 dB if the perforation was closed compared to 3.38 dB after an unsuccessful procedure. CONCLUSION: The success rate of a myringoplasty is dependent of the skills of the surgeon and type of graft used and varies between 91.9 and 52.0% depending on these factors.

Pneumococcal serotype 19A is the major cause of pediatric acute otitis media with ruptured tympanic membrane in Addis Ababa, Ethiopia, 5 years after the introduction of the ten-valent pneumococcal conjugate vaccine.

INTRODUCTION: In Ethiopia, there is a lack of data on pneumococcal serotypes causing acute otitis media (AOM) in children. We aimed to study the etiology, pneumococcal serotypes and antimicrobial resistance patterns of isolates from children with AOM with spontaneous perforation of the tympanic membrane (SPTM). METHODS: We carried out a prospective observational study in children with AOM with SPTM, aged 0-15 years in Addis Ababa, Ethiopia. Middle ear fluid was collected using sterile swabs, cultured and antibiotic susceptibility testing was performed. Serotypes of Streptococcus pneumoniae were determined by sequencing the cpsB gene and by the Quellung reaction. RESULTS: A total of 55 children were enrolled. Out of 55 samples that were cultured, 52 (94.5%) were culture positive for a total of 66 bacterial species, and 56.4% (31/55) samples were positive for 41 (62.1%) known pathogenic bacterial species. The most common pathogenic bacterial isolates were S. pneumoniae (36.6%), Staphylococcus aureus (19.5%), Streptococcus pyogenes (14.6%) and Haemophilus influenzae (12.2%). Serotype 19A (73.3%) was the predominant pneumococcal serotype. There was a high rate of non-susceptibility to penicillin (86.6%) and trimethoprim/sulfamethoxazole (80%) among pneumococcal isolates. Out of 21 different isolates tested for amoxicillin susceptibility, 15 (71.4%) were resistant. CONCLUSIONS: Pneumococcal serotype 19A was the predominant cause of AOM with SPTM in children in Addis Ababa, Ethiopia, 5 years after introduction of PCV10. There was a high rate of resistance to commonly prescribed antibiotics. The study highlights the need for wide scale surveillance of the etiology and antimicrobial susceptibility of AOM in Ethiopian children.

Correlation Between Sensorineural Hearing Loss and Chronic Otorrhea.

Many studies have been trying to correlate chronic otorrhea, both in children and in adults, with the sensorineural hearing loss in the affected ear, but have been obtaining contradictory results. This loss might be due to the likely toxicity of the bacteria involved, effects of inflammatory cytokines, or constant use of ototoxic antibiotics. All the studies evaluated up to the present date compared the affected ear with the normal contralateral ear. From the digitized archive of otological surgery files of the Department of Otorhinolaryngology, the ears of patients with chronic otorrhea were evaluated visually and compared with the normal contralateral ears. Ears with otorrhea were also compared to ears with dry tympanic perforation of other patients. Ears with suppuration were evaluated for cholesteatoma. The duration of otorrhea was taken into account. The sensorineural hearing threshold was evaluated for the frequencies of 500, 1000, 2000, and 4000 Hz. A total of 98 patients with chronic otorrhea and 60 with dry tympanic membrane perforation were evaluated. From a statistical study, a correlation between sensorineural hearing loss and the chronic otorrhea was observed, in comparison both with contralateral normal ears and with dry perforated ears of other patients. There was no relationship with the duration of suppuration or with whether this was due to cholesteatoma. Sensorineural hearing loss occurs in ears with chronic otorrhea. The duration of otorrhea and the etiology of suppuration did not influence the hearing loss. The great majority of otorrhea cases begin during childhood.
