Abstract
Trauma to the ear is typically attributed to its location in the craniofacial skeleton. TM is prone to rupture, tear, or perforation when traumatized. Etiological factors may be classified according to the pathogenetic mechanisms (air-pressure change, heat, solids, water pressure). MATERIALS & METHOD This is a prospective study of 70 patients with traumatic tympanic membrane perforation between January 2019 and December 2022. Inclusion and exclusion criteria applied and results interpreted. RESULTS Traumatic TM affects all age groups with a mean age of 27.94 ± 4.76 years. Traumatic TM affects all age groups with a mean age of 27.94 ± 4.76 years, with the highest incidence among the middle-aged groups 61.4%. The male-to-female ratio was found to be 1.9:1, with high predominance among male patients (65.7%) with a frequency of 57.1% for slap injury group in our study contrary to others. Spontaneous healing was observed in 88.6% over a follow-up period of 12 weeks in this study. Our study has not shown that associated comorbidities influence healing (P = 0.550). About 45.5% Marginal perforations have not healed in 12 weeks follow-up period as compared to central perforations 5.1%. CONCLUSION There is a high predominance of TM perforation among male patients in our study may be attributed to activity. Spontaneous healing is more common. Duration of healing was significantly affected by the size of the perforation with longer duration for large perforations and vice versa. It is observed in this study that the duration of spontaneous healing is longer in blast injuries when compared to other kinds of injuries. A significant proportion of marginal perforations that have not healed in our study may be attributed to annular ligament involvement.

Abstract
OBJECTIVE To date, there is no consensus about the benefits of paper patching over spontaneous healing in the management of isolated acute traumatic tympanic membrane perforations (IATTMP). In this systematic literature review and case series, we compared paper patching of IATTMP to spontaneous healing in terms of healing rate and time to heal. DATABASES REVIEWED A systematic literature search of English-language studies published from 1/1975 to 9/2020 was conducted using PubMed via MEDLINE, and 201 studies were identified. Another 346 studies were derived from the references of those articles. Twenty-four studies remained after omitting duplications and articles that did not meet the inclusion criteria. METHODS Demographics, medical history, physical examination, and audiometric results in the selected publications and in a new series of patients treated for IATTMP between 1/2018 and 1/2021 in a single tertiary referral center were retrieved and analyzed. RESULTS The literature review yielded 2796 ears of which 466 underwent paper patching (intervention arm). Complete perforation healing was documented in 67-97% of control arm and 92-93% of intervention arm. Our new series included 29 ears of which six underwent paper patching. Complete healing was observed in 83% and 78% in the interventional and control arms, respectively. CONCLUSIONS Although paper patching and watchful waiting had similar success rates in patients with IATTMP, healing after paper patching was slightly quicker among our patients. Patching is a readily applicable and technically simple office-based intervention that should be preferentially considered for IATTMP.

[PMID: 34570265 PMCID: PMC9130167 DOI: 10.1007/s00405-021-07078-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2021] [Accepted: 09/07/2021] [Indexed: 11/29/2022]
Abstract
Purpose Injury or inflammation of the middle ear often results in the persistent tympanic membrane (TM) perforations, leading to conductive hearing loss (HL). However, in some cases the magnitude of HL exceeds that attributable by the TM perforation alone. The aim of the study is to better understand the effects of location and size of TM perforations on the sound transmission properties of the middle ear. Methods The middle ear transfer functions (METF) of six human temporal bones (TB) were compared before and after perforating the TM at different locations (anterior or posterior lower quadrant) and to different degrees (1 mm, ¼ of the TM, ½ of the TM, and full ablation). The sound-induced velocity of the stapes footplate was measured using single-point laser-Doppler-vibrometry (LDV). The METF were correlated with a Finite Element (FE) model of the middle ear, in which similar alterations were simulated. Results The measured and calculated METF showed frequency and perforation size dependent losses at all perforation locations. Starting at low frequencies, the loss expanded to higher frequencies with increased perforation size. In direct comparison, posterior TM perforations affected the transmission properties to a larger degree than anterior perforations. The asymmetry of the TM causes the malleus-incus complex to rotate and results in larger deflections in the posterior TM quadrants than in the anterior TM quadrants. Simulations in the FE model with a sealed cavity show that small perforations lead to a decrease in TM rigidity and thus to an increase in oscillation amplitude of the TM mainly above 1 kHz. Conclusion Size and location of TM perforations have a characteristic influence on the METF. The correlation of the experimental LDV measurements with an FE model contributes to a better understanding of the pathologic mechanisms of middle-ear diseases. If small perforations with significant HL are observed in daily clinical practice, additional middle ear pathologies should be considered. Further investigations on the loss of TM pretension due to perforations may be informative.

Abstract
PURPOSE Platelet-rich fibrin (PRF) results in satisfactory wound healing. This analysis focuses on assessing the effectiveness of PRF in the treatment of tympanic membrane (TM) perforations. MATERIALS AND METHODS The literature was searched using PubMed, Embase, Cochrane Library and Web of Science databases from inception to February 28th, 2021. The following healing and hearing outcomes were measured: closure rate, pre-and postoperative auditory results, and incidence of postoperative infections. Data were pooled and expressed as the odds ratio (OR). RESULTS Ten studies were eligible for qualitative review, and seven of them were included for the final quantitative comparison. The OR for the closure rate of acute perforations was 4.30 (95% CI 1.35-13.70, I2 = 0%), and the OR in the chronic subgroup was 5.42 (95% CI 2.57-11.43, I2 = 0%). The total OR value for the completed closure rate was 5.10 (95% CI 2.72-9.54, I2 = 0%), indicating that the utilization of PRF can enhance the closure of both acute and chronic perforations. The qualitative review did not find improved hearing results with the use of PRF. In addition to promoting closure, PRF can reduce the incidence of infections (OR = 0.14). The sensitivity analysis did not change the final results, and there was no publication bias in this analysis. CONCLUSION PRF can increase the closure rate of acute perforations, enhance the survival rate of autografts in TM surgeries and reduce the incidence of infections. However, the literature indicates that PRF does not influence the hearing outcomes. This study shows that PRF is an effective agent for TM regeneration.

Abstract
OBJECTIVES/HYPOTHESIS The aim of the study was to investigate the healing rates, the restoration of hearing, and the time for complete healing of paper patching versus watchful waiting for traumatic tympanic membrane perforations (TTMPs). STUDY DESIGN Systematic review with meta analysis. METHODS Publications were selected by a search on "PubMed," "Embase," and "Web of Science." A meta-analysis of risk ratios for paper patching (intervention arm) and watchful waiting (control arm) was performed. RESULTS Five studies describing 393 TTMPs were included in the quantitative meta-analysis. TTMP healing rates ranged between 84.2% and 95.2% in the intervention arm and between 76.7% and 84.8% in the control arm. The pooled risk ratio of healed TTMPs was significantly higher in the intervention arm than in the control arm (risk ratio: 1.12, 95% confidence interval: 1.04-1.21). CONCLUSIONS TTMPs have high healing potential with and without intervention. The healing rate of paper patching was superior to that of watchful waiting alone.

Abstract
Objective: To investigate the effectiveness of basic fibroblast growth factor (bFGF) versus placebo or no intervention in the treatment of tympanic membrane (TM) perforations from randomized controlled trials (RCTs), prospective and retrospective studies. Data Sources: PubMed, EMBASE, and Cochrane databases were screened from their inceptions to June 2019. Study Selection: Inclusion criteria: 1) English language; 2) observational (retrospective or prospective) or treatment (RCT) studies; 3) reported the outcomes on the application of bFGF in adult or pediatric population. Exclusion criteria: 1) studies without a control group; 2) animal studies, in vitro studies, review studies, and case reports. Data Extraction: Number of patients, cause of TM perforation, perforation size, treatment, mean age, follow-up time, sex, closure rate, healing time, mean air-bone gap improvement. Data Synthesis: A total of 14 studies were included, including seven RCTs and seven non-RCTs with a total of 1,072 participants. The odds ratio for closure rate of bFGF treatment was 7.33 (95% confidence interval [CI], 4.65 to 11.53; p < 0.01; I2 = 44%) and the standardized mean difference (SMD) for healing time was –5.89 (95% CI: –7.85 to –3.93, p < 0.01, I2 = 98%), suggesting bFGF application has a significant effect on closure of TM perforations. However, no significant change in hearing (SMD: 0.08, 95% CI: –0.11 to 0.27, p = 0.39, I2 = 0%) was seen as a result of bFGF treatment. Conclusions: Our meta-analysis has revealed that the application of bFGF can significantly enhance the closure rate as well as shorten the healing time for TM perforations. In terms of hearing, there is as yet no evidence that bFGF has a significant effect. Given its ease, availability, and safety, bFGF can be used effectively for TM repair.

Abstract
BACKGROUND Tympanic membrane (TM) perforation is quite common in the clinical setting. Chronic TM perforations require surgical treatments such as myringoplasty. Currently, platelet-rich plasma (PRP) is a novel, effective substance that is increasingly utilized for TM perforation repair. This study aims to evaluate the effectiveness of PRP in the application of TM perforation repair. METHODS A systematic search was conducted to screen the Medline, Embase, Cochrane, Scopus and Web of Science databases up to July 2020. Studies were identified in accordance with the selection criteria by two coauthors independently. Data regarding the healing and hearing outcomes were pooled and analyzed via Review Manager version 5.3 and STATA version 12.0 software. Odds ratio (OR) was utilized to compare the closure rate. Furthermore, the results of hearing improvements and incidence of complications were also compared to evaluate the effectiveness of PRP. RESULTS A total of eight studies with 455 participants were eligible according to the selection criteria. Compared to conventional surgery, the OR of closure was 2.70 (95% CI: 1.27 to 5.76, P = 0.01, I2 = 0%) in randomized controlled trial (RCT) subgroup and 6.18 (95% CI: 2.22 to 17.25, P = 0.0005, I2 = 0) in non-RCT subgroup. The overall OR of closure was 3.69 (95% CI: 2.02 to 6.74, P<0.0001, I2 = 0%), suggesting a significant effect on the healing of TM perforation. Between preoperative and postoperative hearing results, there is no statistical difference between the PRP and the control groups. Additionally, the use of PRP resulted in a lower incidence of complication than the use of conventional approaches. CONCLUSION The application of PRP during the TM surgeries can enhance the closure rate, provide similar hearing improvements and decrease the incidence of postoperative complications. Given these advantages, PRP can be considered an effective treatment for TM regeneration.

Abstract
BACKGROUND Traumatic eardrum perforation is a common presentation in otorhinolaryngologic practices and emergency clinics. A consistent management strategy (active intervention vs. watchful waiting) is, however, still lacking. OBJECTIVE In the following study, the outcome of watchful waiting is analyzed and presented. MATERIALS AND METHODS A collective of 272 patients presenting at two different specialist ENT practices within days of traumatic tympanic membrane perforation from June 2002 to March 2019 were analyzed. Treatment was non-surgical, with prospective monitoring. Whereas antibiotics were not given at all in one practice, they were given only upon signs of infection in the other practice. The outcome was evaluated retrospectively on the basis of patient files. RESULTS The collective consisted of 185 males and 87 females. Mean age was 30 years (range: 7 months to 82 years). The perforations were most commonly located in the upper anterior and lower posterior quadrants. According to Griffin grading, the size was grade I in 97%. The three most common causes were impact to the ear, barotrauma, and foreign bodies. Under a watchful waiting regimen, 95% of the patients presenting for follow-up checks showed complete closure. CONCLUSION Watchful waiting can be assessed as appropriate in traumatic eardrum perforation, provided otorhinolaryngologic follow-up is ensured. An exception is blast injury, which is now much less common in Central Europe, as this is associated with a risk of secondary cholesteatomas. In these rare cases, active treatment with surgical exploration of the middle ear including relining the perforation is indicated.

Abstract
HYPOTHESIS The scarred rim of chronic tympanic membrane (TM) perforation contains keratinocytes with potential for regeneration while maintaining their morphological and genetic characteristics. BACKGROUND The squamous epithelium of the TM has a good regeneration capacity. Successful isolation and expansion of human TM keratinocytes (hTMKR) was reported from a full, en-bloc, healthy TM. METHODS Trimmed margins of the TM perforation (harvested during tympanoplasty) underwent enzymatic digestion (collagenase or trypsin) and were seeded either with serum-containing medium (SCM) or keratinocyte serum-free medium (KSFM) and progenitor cell growth medium (PR) (KSFM:PR, 1:1). Gene expression analysis by real-time qRT-PCR was used to compare between human TM cells derived from scarred perforation margins (hTMKR), normal human skin keratinocytes (NhSKR), and human fibroblasts. RESULTS Twelve patients were included in the study. In 9 of 12 cases (75%) single-cell isolation with fibroblastic or epithelial cell morphology (or both) was achieved. Cells seeded with KSFM:PR yielded epithelial morphology (hTMKR) while SCM culturing resulted in a fibroblastic morphology (hTMFib). Gene expression analysis revealed significant higher expression of VCAN (p = 0.002) and FOXC2 (p = 0.015) at the mRNA levels (normal hTMKR markers) in hTMKR compared to NhSKR. In addition, a comparison of gene expression between hTMKR and hTMFib revealed significantly higher levels of both VCAN (p = 0.045) and SLC6A14 (p = 0.036) among hTMKR. CONCLUSION For the first time, we developed a protocol to isolate hTMKR from scarred TM perforation margins. Furthermore, we succeeded in achieving tissue expansion that preserved the characteristic of healthy TM cells. This study bridges "regenerative medicine" approach with clinical and surgical objectives.

Abstract
Hearing is a critical sense to military performance. The ability to detect, identify, and localize sounds, the ability to maintain spatial awareness on the battlefield and the awareness to control one's own noise production can be vital to troop's stealth, survivability, and lethality. Hazardous noise is an environmental public health threat encountered in training at war, and in many off-duty activities. The risk to hearing and the resultant damage from any of these hazardous exposures is generally invisible, insidious and cumulative. Regardless of the source of injury, hearing loss degrades the sensor that integrates Service Members with their environment, provides for unity of effort, and ensures command and control.Acoustic trauma-induced hear loss and tinnitus are the two most prevalent disabilities in veterans, with over 765,000 cases in the Gulf War era alone. To counter this threat, it is necessary to push for early identification and early intervention through a trusted surveillance system. Success will require advocacy, education, and encouragement of self-reporting for evaluation following symptomatic noise exposures. This Clinical Practice Guideline (CPG) is a step to ensure the hearing health, readiness, protection, and care of Service Members. This will in turn optimize troop performance and minimize injury risk and mishap.

Abstract
OBJECTIVE We investigated the medical costs and effects of ofloxacin drops (OFLX), gelatin sponge patches, spontaneous healing, and endoscopic myringoplasty on healing in large tympanic membrane perforations (TMPs). METHODS In total, 100 patients with large traumatic TMPs involving >50% of the eardrum were randomly assigned to OFLX, gelatin sponge, spontaneous healing, or endoscopic myringoplasty treatment groups. Medical costs, closure times, and closure rates were compared among groups at 6 months. RESULTS The closure rates in the OFLX, gelatin sponge, spontaneous healing, and endoscopic myringoplasty groups were 95.7%, 82.6%, 58.3%, and 91.7%, respectively (P = 0.05). The mean closure time was 13.73 ± 6.14 days in the OFLX group, 15.89 ± 4.95 days in the gelatin sponge group, 48.36 ± 10.37 days in the spontaneous healing group, and 12 days in the endoscopic myringoplasty group (P < 0.001). The mean medical costs in US dollars were $15.53 ± 3.15, $103.64 ± 111.58, $11.17 ± 1.33, and $715.90 in the OFLX, gelatin sponge, spontaneous healing, and endoscopic myringoplasty groups, respectively (P < 0.001). CONCLUSION Although the gelatin sponge and myringoplasty treatments significantly shortened the closure time compared with spontaneous healing, the gelatin sponge patch did not significantly improve the closure rate, and the medical cost of myringoplasty was significantly higher than that of the other treatments. In contrast, OFLX significantly shortened closure time and had a higher closure rate than spontaneous healing, and the medical costs were lower than those of the gelatin sponge and myringoplasty procedures.

Abstract
Chronic ear disease is composed of a spectrum of otologic disorders intrinsically tied to Eustachian tube dysfunction. Presentation can range from asymptomatic findings on physical examination to critically ill patients with intracranial complications. Internists represent the first line in diagnosis of these conditions, making awareness of the common signs and symptoms essential. With surgical management often required, partnership between internal medicine and otolaryngology is fundamental in the management of patients with chronic ear disease.

Abstract
OBJECTIVE The use of epidermal growth factor (EGF) to achieve closure of human traumatic tympanic membrane perforations (TMPs) was recently reported. However, pretreatment factors affecting healing outcomes have seldom been discussed. This study was performed to evaluate pretreatment factors contributing to the success or failure of TMP healing using EGF. DESIGN AND PARTICIPANTS This was a retrospective cohort study of 95 TMPs who were observed for at least 6 months after EGF treatment. Eleven factors considered likely to affect healing outcome were evaluated by univariate and multivariate logistic regression analyses. INTERVENTIONS Each traumatic TMP was treated by daily topical application of EGF. The main outcome measures were complete closure versus failure to close and mean closure time. RESULTS A total of 95 patients were included in the analyses. The total closure rate was 92.6% at 6 months, and the mean closure time was 10.5 ± 4.8 days. The closure rate was not significantly different according to the duration of perforation ≤3 days and >3 days (P = 0.816). However, the mean closure time was significantly different according to the duration of perforation (P < 0.001). The perforation size did not affect the closure rate (P = 0.442). The mean closure time in the low-dose EGF group was significantly shorter than that in the high-dose EGF group (P = 0.001). Logistic regression analyses showed that perforations with preexisting myringosclerosis were more likely to fail to close compared to those without preexisting myringosclerosis (P = 0.001). Multivariate logistic regression analyses showed that the duration of perforation (P = 0.011), size of perforation (P < 0.001), and involvement of the malleus in perforation (P = 0.005) were factors independently correlated with closure time. CONCLUSIONS Daily application of EGF can be used to treat all traumatic TMPs. The size of the perforation and inverted edges did not affect the closure rate, and the most beneficial dosage was sufficient to keep the eardrum moist. Multivariate logistic regression analyses revealed a significant correlation between preexisting myringosclerosis and failure to heal. Nevertheless, the size of perforation, starting time of application, and malleus injury were independent prognostic factors for prolonged healing time.

Abstract
To increase healing rate of tympanic membrane (TM) perforations, patching procedure has been commonly conducted. Biocompatible, biodegradable patching materials which is not limited across cultures is needed. The authors evaluated the effectiveness of novel transparent duck's feet collagen film (DCF) patch in acute traumatic TM perforation. This procedure was compared with spontaneous healing and paper patching. Cell proliferation features were observed in paper and DCF patches. Forty-eight TMs of 24 rats were used for animal experiment, perforations were made on each TMs, and divided into three groups according to treatment modality. Sixteen were spontaneously healed, 16 were paper patched and 16 were DCF patched. The gross and histological healing results were analyzed. Both paper and DCF patch showed no cytotoxicity, but cell proliferations were more active in DCF than paper in early stage. In animal study, the healing of TM perforations were completed within 14 days in all three groups, but found to be faster in DCF patch group than paper patch or spontaneous healing group. The DCF patches were transparent and size of DCF patches were gradually decreased, so there were no need to remove the DCF patches to check the wound status or after the completion of healing. According to this result, authors concluded that DCF patch is transparent, biocompatible and biodegradable material, and can induce fast healing in acute traumatic TM perforations.

Abstract
OBJECTIVE We evaluated the effects of fibroblast growth factor-2 (FGF-2) delivered via a Gelfoam patch on the regeneration of myringosclerotic traumatic tympanic membrane perforations (TMPs) lying close to the malleus. STUDY DESIGN A prospective, randomized, controlled clinical study. SETTING A university-affiliated teaching hospital. SUBJECTS AND METHODS We prospectively analyzed, in a randomized manner, the outcomes of treatment for traumatic TMPs constituting >25% of the tympanic membrane. The closure rates, closure times, and otorrhea rates were compared among patients treated via FGF-2-containing Gelfoam patches, Gelfoam patches alone, and observation only. RESULTS We analyzed data from 138 patients. The perforation closure rates in the FGF-2 plus Gelfoam patch, Gelfoam patch, and observation alone groups were 97.9, 89.8, and 70.7%, respectively. Both the FGF-2 plus Gelfoam and Gelfoam alone groups exhibited significantly higher closure rates than the observational group (both p<0.05).The mean closure times were 15.7±5.1, 24.8±4.9, and 35.7±9.2days in the FGF-2 plus Gelfoam patch, Gelfoam patch alone, and observation alone groups, respectively. The FGF-2 plus Gelfoam patch group exhibited a significantly shorter closure time than the Gelfoam patch alone and observation alone groups (p<0.05). The incidences of purulent otorrhea were 14.6, 6.1, and 4.9% in the FGF-2 plus Gelfoam patch, Gelfoam patch alone, and observation alone groups, respectively. Surprisingly, 7 of 7 (100.0%) perforations associated with purulent otorrhea completely closed in the FGF-2 plus Gelfoam patch group; however, no such perforation healed in either the Gelfoam alone or observation alone group. CONCLUSIONS FGF-2 plus Gelfoam patching significantly shortened the closure time compared to observation and Gelfoam patching alone, and it significantly improved the closure rate (compared to observation alone) of myringosclerotic perforations lying close the malleus. FGF-2 plus Gelfoam patching is a valuable, minimally invasive alternative treatment that may be readily applied to outpatient settings.

Abstract
OBJECTIVE This study investigated the influence of the degree of bleeding from the remnant eardrum on the spontaneous healing of human traumatic tympanic membrane perforations (TMPs). STUDY DESIGN A case series with chart review. SETTING A tertiary university hospital. MATERIALS AND METHODS The clinical records of traumatic TMP patients who met the case selection criteria were retrieved and categorized into two groups based on the documented degree of bleeding from the remnant eardrum: with and without bleeding. The demographic data and spontaneous healing outcomes (i.e., healing rate and duration) of these two TMP types were analyzed using the chi-squared test or t-test. RESULTS One-hundred and eighty-eight cases met the inclusion criteria and were analyzed. Of these, 58.5% had perforations without bleeding and the remaining 41.5% had perforations with bleeding. The overall closure rate at the end of the 3-month follow-up period was 90.9% for perforations without bleeding and 96.2% for perforations with bleeding; the difference was not statistically significant (P>0.05). However, the average closure time differed significantly between the two groups (P<0.05): 29.4±3.7days for perforations without bleeding and 20.6±9.2days for perforations with bleeding. The closure rate was significantly different between the groups (62 vs. 15.6%, P<0.01) within 2weeks for medium-sized perforations. In total, 11 (39.3%) large-sized perforations achieved complete closure in the group with bleeding, while none of the large-sized perforations closed in the group without bleeding within 2weeks. The closure rate of medium-sized perforations was not significantly different (79.2 vs. 92%, P>0.05) between the groups without and with bleeding within 4weeks, while the closure rate of large-sized perforations was significantly different between the groups without and with bleeding (27.2 vs. 75%, P=0.0). CONCLUSION This study shows that traumatic TMPs with bleeding significantly shortened the closure time compared to TMPs without bleeding. This finding indicates a significant correlation between the prognosis of traumatic TMPs and the degree of eardrum bleeding: severe bleeding from and a hematoma in the remnant eardrum appear to be good signs.

Abstract
We investigated the utility of the duck-feet collagen extraction patching procedure in the traumatic tympanic membrane (TM) perforation via a comparison with spontaneous healing or paper patch. Fifty-six ears of adult male Sprague-Dawley rats, each weighing in the range of 250 to 300 g, were used for the animal studies. Sixteen rats had one-side ear in the control group and the opposite-side ear in the treated groups. The remaining twelve rats had a one-side ear with the duck-feet collagen patch and the opposite-side ear with a paper patch. The proliferating cell nuclear antigen (PCNA) expression cells were calculated among the 200 basal cells, and the expression percentage was identified as the labeling index. The healing of the perforation in the duck-feet collagen patch group was confirmed to be more rapid compared to the healing of the other groups. PCNA staining was observed in the migrating portion of PCNA enhanced cell to collagen scaffold in Post operative day (POD) 7 of collagen patch group. Thus, the adhesive effect of the duck-feet collagen patch to perforated margin was better than that of the paper patch. After completing the healing process, the collagen patch shrank and detached from the tympanic membrane (POD 14). In this study, we confirmed that the use of a duck-feet collagen patch had the advantage of early healing, inducing natural TM contour, and disappearing ability after the patch effect is complete.

Abstract
Background and Objectives The aim of this study was to investigate how fibrinogen-based collagen fleece (Tachocomb®) graft myringoplasty (FCGM), performed under microscopic guidance, improves both hearing and tympanic membrane tissue repair in patients with traumatic tympanic membrane perforation (TMP). Subjects and Methods Between August 2009 and March 2015, a total of 52 patients with traumatic TMP visited the department of otorhinolaryngology at a secondary medical center. Twenty-nine of these underwent FCGM under microscopic guidance in our outpatient clinic. For each patient, we recorded the location and size of the perforation, the time elapsed from the onset of TMP until the myringoplasty, and the hearing level both before and after myringoplasty. Results The TMP closed completely in all cases (29 of 29 patients). After myringoplasty, the postoperative air-bone gap (ABG) differed significantly from the preoperative ABG. Three of the 29 patients (10.3%) experienced complications. Specifically, 2 presented with otorrhea after FCGM, but conservative management led to improvement without recurrence of perforation. One patient showed delayed facial palsy 1 week after the procedure. The condition of this patient also improved and the palsy was not permanent. Conclusions FCGM may be an effective treatment option in case of traumatic TMP. The procedure requires no hospitalization, and can be used to avoid traditional tympanoplasty.

Abstract
Otitis media with effusion (OME) is the most frequent illness in children. Surgical treatment options include ventilation tube insertion, adenoidectomy or both. Opinions regarding the risks, benefits and intubation period of ventilation tube insertion vary greatly. To determine the appropriate time for when to remove asymptomatic longterm ventilation T-tubes in children. In this prospective study, we analyzed the results of 120 pediatric patients (6-12 years) (240 ears) with persistent OME; we employed the Goode T-silicone tubes. We intentionally planned to remove the tubes at different time points of the study and divided our patients randomly into four subgroups with 30 patents (60 ears in each) according to the intubation period; group I: intubation for 6 months, group II: intubation for 12 months, group III: intubation for 18 months and group IV: intubation for 24 months. The relationship between intubation period and OME recurrence, the rate of persistent tympanic membrane (TM) perforation, granulation tissue or discharge near the tympanostomy tubes, normalization of Eustachian tube function and change of hearing level was analyzed in each patient group. The χ2 analysis showed that the rate of normalization of ET function was significantly higher when tubes were removed after 12-months of intubation (P = 0.002), the rate of OME recurrence was significantly higher when tubes were removed before 12-months of intubation (P = 0.004), The rate of otorrhea significantly increased after 12-months of intubation, development of granulation around tubes was significantly higher after 18-months of tube insertion. The rate of appearance of permanent TM perforation significantly increased after 18-months from tube insertion (P = 0.008). Adenoidectomy did not significantly influence the recurrence rate of OME or the rate of persistent TM peroration after tube removal. Our present results suggest that the appropriate intubation period for healing OME in children would be at 12-18 months. Also, we can conclude that longterm ventilation tubes are recommended to avoid repeated intubation and to obtain sufficient results, although their performance is not always satisfactory; mainly because of accompanying complications.

Abstract
AbstractBackground:The treatment of traumatic tympanic membrane perforations varies in different investigations, ranging from observation to early surgical repair. The present study aimed to focus on the closure rate and the closure time in a group of patients treated with a watchful waiting policy.Methods:The study comprised 133 consecutive patients with a total of 137 perforations. Data were evaluated in terms of aetiology, location and size of perforation, audiometric findings, closure rate, and closure time.Results:The overall closure rate was 97 per cent. For patients with a known closure time within three months, the median closure time was between three and four weeks. The probability of spontaneous closure over time was further analysed with Kaplan–Meier plots, for those perforations with known closure times and for all perforations including those with unknown closure times. Perforation size was the only significant determining factor for closure time.Conclusion:Small perforations had a high probability of spontaneous closure within three to four weeks, justifying a watchful waiting policy. Larger uncomplicated perforations might warrant early surgical repair, depending on the patient's needs and the availability of surgery.

Abstract
Objectives The silk patch is a thin transparent patch that is produced from silk fibroin. In this study, we investigated the treatment effects of the silk patch in patients with traumatic tympanic membrane perforation (TTMP). Methods The closure rate, otorrhea rate, and closure time in all patients and the closure time in successful patients were compared between the paper patch and silk patch groups. Results Demographic data (gender, site, age, traumatic duration, preoperative air-bone gap, and perforation size and location) were not significantly different between the two groups. The closure rate and otorrhea rate were not significantly different between the two groups. However, the closure time was different between the two groups (closure time of all patients, P=0.031; closure time of successful patients, P=0.037). Conclusion The silk patch which has transparent, elastic, adhesive, and hyper-keratinizing properties results in a more efficient closure time than the paper patch in the treatment of TTMP patients. We therefore believe that the silk patch should be recommended for the treatment of acute tympanic membrane perforation.

Abstract
OBJECTIVE The use of growth factors to achieve closure of human traumatic tympanic membrane perforations (TMPs) has recently been demonstrated. However, pretreatment factors affecting healing outcomes have seldom been discussed. The objective of this study was to evaluate pretreatment factors contributing to the success or failure of healing of TMPs using fibroblast growth factor-2 (FGF-2). DESIGN AND PARTICIPANTS A retrospective cohort study of 99 patients (43 males, 56 females) with traumatic TMPs who were observed for at least 6 months after FGF-2 treatment between March 2011 and December 2012. Eleven factors considered likely to affect the outcome of perforation closure were evaluated statistically using univariate and multivariate logistic regression analysis. INTERVENTIONS Each traumatic TMP was treated by direct application of FGF-2. MAIN OUTCOME MEASURES Complete closure versus failure to close. RESULTS In total, 99 patients were analyzed. The total closure rate was 92/99 (92.9%) at 6 months; the mean closure time was 10.59 ± 6.81 days. The closure rate did not significantly differ between perforations with or without inverted edges (100.0% vs. 91.4%, p = 0.087), among different size groups (p = 0.768), or among different periods of exposure to injury (p = 0.051). However, the closure rate was significantly different between the high- and low-dose FGF-2 groups (85.0% vs. 98.3%, p = 0.010) and between perforations where the umbo or malleus was or was not involved in perforation (85.4% vs. 98.3%, p = 0.012). Additionally, univariate logistic regression analysis tests showed that it was difficult to achieve healing of these perforations with a history of chronic otitis media or residual TM calcification (p = 0.006), the umbo or malleus was involved in perforation (p = 0.038), and with a high dose of FGF-2 (p = 0.035) compared with control groups. Multivariate logistic regression analysis showed that only a history of chronic otitis media and residual TM calcification and perforation close to the umbo or malleus were associated with non-healing of the TM perforation (p = 0.03 and p = 0.017, respectively) with relative risk factors. CONCLUSIONS Direct application of FGF-2 can be used in all traumatic TMPs, the size of the perforation and inverted edges did not affect the closure rate, and the most beneficial dose was sufficient to keep the residual eardrum environment moist, but without adding liquid. Additionally, multivariate logistic regression analysis revealed that a large perforation was not a major risk factor for nonhealing of TM perforations. However, a history of chronic otitis media, residual TM calcification and involvement of the umbo or malleus in perforation were significant risk factors.

Abstract
OBJECTIVE The aim of this study was to revalidate and reproduce a chronic tympanic membrane perforation animal model. STUDY DESIGN Prospective, animal study. METHODS Eight female chinchillas underwent bilateral thermal myringotomy. The edges of the perforation were folded inward using microflaps. The perforations were followed over time to monitor the course of closure. RESULTS Two animals were excluded from the study because of ear infection. None of the other tympanic membrane perforations remained open. The closing time varied from 4 to 6 weeks. CONCLUSIONS Our findings demonstrate that the thermal myringotomy combined with infolding technique is not a reliable and consistent method to create a chronic tympanic membrane perforation. The closing time is shorter than expected and varies among the study subjects. There is a clear need for developing a reliable chronic tympanic membrane perforation model.

Abstract
The most common etiologies of tympanic membrane perforation are infections and trauma. Objective The objective of the present study was to assess the healing of traumatic tympanic membrane perforation in rats. Methods The tympanic membrane from male Wistar rats was perforated in the anterior and posterior portions to the handle of the malleus. Five tympanic membranes were evaluated 3 days after tympanic perforation; 5 after 5 days; 5 after 7 days; 3 after 10 days; and 4 after 14 days. The tympanic membranes were submitted to histopathological evaluation after hematoxylin–eosin staining. Results Tympanic membrane closure occurred at about 7–10 days after injury and the healing process was complete by day 14. The proliferative activity of the outer epithelial layer was present close to the handle of the malleus and to the tympanic annulus. Conclusion The spontaneous healing process of the tympanic membrane starts from the outer epithelial layer, with later healing of the lamina propria and the mucosal layer.

Abstract
OBJECTIVE The goal of this study was to evaluate the effects of crust formation on the healing of traumatic, dry, and minor-sized tympanic membrane perforations (TMPs) in humans. STUDY DESIGN Case series with a chart review. SETTING Tertiary university hospital. MATERIALS AND METHODS The clinical records of patients with traumatic TMPs who met the case selection criteria were retrieved and categorized according to the presence of a crust and the timing of crust formation into three groups: no crust, early crust formation, and late crust formation. Healing outcomes (i.e., healing rate and time) in the three groups were analyzed. RESULTS In total, 83 patients were analyzed. The perforation closure rates were 92%, 100%, and 78% in the groups with no-crust, early crust formation, and late crust formation, respectively. No significant difference was seen between the groups with no-crust and with late crust formation (p>0.05). By contrast, closure rates differed significantly between the early and late crust formation groups (p<0.05). Overall, the no-crust and early crust formation groups showed shorter healing times compared with the late crust formation group (p<0.05). However, closure times did not differ significantly between groups with early crust formation and no crust (p>0.05). CONCLUSIONS Crust formation at the margin of a traumatic TMP may serve as a predictor of healing outcome. Compared with perforations with early crust formation or no crust, late crust formation can result in delayed healing and failure to close completely.

Abstract
To review the presentation, types and aetiology of ear trauma and various factors affecting ear trauma in our patients over a 5 year period. All patients treated for ear trauma over a 5 year period were studied using their clinical records. Data extracted were analysed using SPSS version 11 software. The results were presented in simple descriptive and tabular forms. Forty-one patients, 18(43.90%) males and 23(56.10%) females were studied, ages 12-43 years, average 26.3 + 5 years. Blows/Slaps (65.85%) from assault was the commonest aetiology while bleeding from the ear (73.17%), hearing loss (70.73%) and tympanic membrane perforation (68.29%) were the most frequent presentations. Ear trauma is common and mostly affects the tympanic membrane. Sudden increase in canal pressure from blows/slaps was the major mechanism of injury. Management outcome was good except for few late presenters with compilations.

Abstract
AbstractObjective:In this study, we evaluated the effect of low-level lasers on the healing of tympanic membrane perforation, one of the most common otological pathologies.Methods and materials:Twenty-four guinea pigs were randomly assigned to either the experimental or control group. One day after the induction of a 2 mm diameter, centred myringotomy in all animals, the tympanic membranes in the experimental group were irradiated with 630 and 860 nm lasers for 10 days. Two weeks later, histological changes in the membranes were evaluated.Results:Tympanic membrane thickening and inflammatory cell infiltration in the tympanic membranes and surrounding tissues were significantly less in the experimental group (p < 0.001). The distance from the external auditory canal wall to the malleus tip did not differ significantly between the two groups (p = 0.42).Conclusion:The results show that the combined application of 630 and 860 nm lasers had a significant effect on the healing of tympanic membrane perforation, and on the prevention of thick fibrotic or atelectatic neomembrane formation.

Abstract
BACKGROUND Children in the developing parts of the world have a high prevalence of chronic suppurative otitis media (CSOM). It is estimated that 65 to 330 million people worldwide have CSOM, yet very little is known about the natural course of the disease. The Inuit population of the Arctic regions is among those with the highest prevalences of CSOM. The aim of this study was to examine the long-term tympanic membrane changes since childhood among Inuit adolescents in Greenland and estimate the proportion of individuals affected by CSOM. METHODS Follow-up study (2009) on a population-based cohort of 591 children originally examined during 1993 to 1994 at 3 to 8 years of age. Follow-up was attempted among 348 individuals still living in the areas. Video otoscopy and tympanometry were used. Data on otologic disease, ear surgery, and antibiotic use for otitis media were collected from medical records. RESULTS Of 226 participants (65% of those contacted; median age, 22 years), 28 (12%) had present CSOM or had been surgically treated. Eleven were new cases of CSOM not seen between 1993 and 1994. Of those with CSOM in the initial study, 39% had healed spontaneously. The proportion of spontaneous healing was not influenced by the age at which CSOM was diagnosed in the initial study. Thirty-nine individuals (17%) had CSOM in either the initial study or at follow-up. Of these, 2 had never received antibiotic treatment for otitis media, and 15 had been treated less than 3 times. Eighty individuals (35%) at follow-up had CSOM, had undergone ear surgery, or had sequelae in the form of circular atrophy or myringosclerosis. CONCLUSIONS The proportion of spontaneous healing and the findings of new cases show that CSOM is a dynamic disease both on the individual as well as on the population level. Every third participant at follow-up had a perforation or sequelae from recurrent or long-lasting perforations, indicating a burden of disease from otitis media larger than what can be estimated in cross-sectional studies. There is a potential for increased treatment of otitis media in this population, which requires raised awareness of the disease in the population and the creation of guidelines customized to conditions in Greenland.

Abstract
The purposes of this study were to investigate the biocompatibility of two different paper patches (carbon and cigarette papers) and compare the adhesion and proliferation features of L929 fibroblast cells by using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT Test) test and scanning electron microscopy (SEM). In this study, time-dependent cytotoxic effects of cigarette and carbon papers used in repairing small traumatic TM perforations were investigated in vitro by using MTT test. And also adhesion and spreading of cells over disk surface were observed by SEM. Cytotoxicity test carried out by MTT analysis on leakage products collected from two types of paper patches at the end of 24 and 48 h revealed no cytotoxicity (P > 0.05). In SEM studies, it was observed that cells started to proliferate over disk surface as a result of 48-h incubation, and SEM revealed that the cell proliferation over cigarette paper was more compared to the one over carbon paper. We believe that this is the first study where biocompatibility and adhesion features of carbon and cigarette paper have been studied by using L929 fibroblast cell culture. As a result, biocompatibility of cigarette paper and also whether cigarette paper was superior to carbon paper in cell attachment and biocompatibility were studied. It was found, by MTT test and SEM test, that cigarette paper had a higher biocompatibility and cell attachment, and thus cigarette paper should be the patch to be preferred in cases where TM perforations are repaired by paper-patch method.

Abstract
OBJECTIVE To compare the outcome of patients with dry traumatic tympanic membrane perforation after spontaneous healing and gelfoam patching with or without perforation edge approximation. DESIGN Prospective clinical study. SETTING University-affiliated teaching hospital. PARTICIPANTS Ninety-one patients with acute dry traumatic tympanic membrane perforation inverted or everted edges were recruited. They were randomly allocated to three groups: spontaneous healing (n=31), gelfoam patching (n=30) and edge-approximation plus gelfoam patching (n=30). Otoscopy and tympanometry were performed before the treatment and at follow-up visits. MAIN OUTCOME MEASURES Healing rate, healing time, ear infection rate and morphological changes during healing process. RESULTS The overall healing rate was 85% in the spontaneous healing group, lower than that in the two gelfoam patching groups (97%), but the difference failed to reach a statistical significance (P>0.05). The average healing time was 30 ± 10.1 days in the spontaneous healing group, significantly longer (P<0.01) than that in the other two groups (16 ± 5.6 and 18 ± 4.7 days, respectively). Middle ear infection rate did not differ significantly (7%, 3% and 3%, respectively). Spontaneous healing resulted in formation of scabs at the perforation edges, which was effectively prevented by gelfoam patching. CONCLUSIONS Gelfoam patching may facilitate healing of traumatically perforated tympanic membrane. Approximation of folded perforation edges is not necessary in gelfoam patching.

Abstract
Recently, a report on a bilateral tympanic membrane (TM) perforation in a patient after long-term treatment with erlotinib was published. The object of this study was to investigate the destructive potential of topical applied epidermal growth factor receptor (EGFR) inhibitors on wound healing of experimental TM perforation in rats by evaluating closure rates and histology. In 12 rats, erlotinib (10 mg/ml) was applied to one TM of each animal and cetuximab (5 mg/ml) to the other side daily for 12 consecutive days. Both the erlotinib group (11.8 days) and cetuximab group (9 days) had prolonged healing latencies compared to a reference value (7 days). We observed differences in the histologic parameters between both groups. Our results suggest that in normal TM, the inhibition of EGFR does not lead to a persistent perforation. However, in case of preexisting TM pathology, a spontaneous perforation in patients under long-term treatment of EGFR inhibitors seems to be possible.

Abstract
OBJECTIVE To review the current evidence for the use of concomitant interventions to reduce the persistent perforation rate following the removal of long-term ventilation tubes. TYPE OF REVIEW A systematic review of the literature and meta-analysis of randomised controlled trials on this topic. SEARCH STRATEGY Medline (1952-2008), EMBASE (1974-2008) and the Cochrane Central Register of Controlled Trials. A combination of search terms were used in a search strategy derived from guidance from the Cochrane collaboration. EVALUATION METHOD A review of all trials by two authors with grading of the level of evidence. RESULTS Fifteen studies using a variety of interventions were identified. CONCLUSION A multi-centre randomised controlled trial is indicated to validate findings of previous studies and elucidate any optimum intervention to reduce the persistent perforation rate.

Int J Pediatr Otorhinolaryngol 2008; 72:1789-93. [PMID: 18849084 DOI: 10.1016/j.ijporl.2008.08.010] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2008] [Revised: 08/12/2008] [Accepted: 08/15/2008] [Indexed: 10/21/2022]
Abstract
OBJECTIVES Traumatic perforations of the eardrum are generally treated conservatively as they tend to heal spontaneously. Retraction pockets of the eardrum, leading to atelectasis of the middle ear and often ultimately though unpredictably, to cholesteatoma formation, are treated in a variety of ways including complex grafting procedures. On the premise that a surgically resected retraction pocket is in essence a traumatic perforation, we examined the results of spontaneous healing of the resected retraction pocket. METHODS Retrospective case note study. PATIENTS A group of 86 ears in 62 patients who had undergone simple excision of the atrophic segment of the eardrum and who had no grafting procedure of the resultant defect, were followed at 6 days, 6-7 weeks and then every 6 months to determine the incidence of spontaneous healing of the eardrum. Audiograms were taken preoperatively, at 7 weeks and between 7 and 15 months postoperative. RESULTS 94.2% of the eardrums (81 out of 86 ears) healed spontaneously without any form of grafting within 7 weeks. Air bone gap showed improvement in 53 patients. Only one of the four ears that failed to achieve closure had postoperative ear discharge. There were no other complications. In 17 ears (19.8%) there was a recurrence of the atelectasis. CONCLUSION Excision of retraction pockets in pediatric ear atelectasis, in principle does not require grafting, as the great majority will heal spontaneously. The spontaneous healing in this study is comparable to reported studies of spontaneous healing of traumatic perforations. Irrespective of the size of the atrophic part of the membrane, recurrence rates for the atelectasis after simple excision is similar to that described in other studies. Retraction pockets may be excised and allowed to heal without risk to the hearing.

Abstract
Developments in the treatment of chronic tympanic membrane perforation have been hindered by the lack of an ideal animal model. It is not appropriate to test such treatments on acute perforations as the majority of these heal spontaneously. An ideal animal model would be one that most closely resembles the human clinical situation. It should be inexpensive, readily available, and easy to create. There have been a number of attempts to create a chronic tympanic membrane perforation model with limited success. All published attempts at chronic tympanic membrane perforations have been reviewed and the limitations of each model are discussed. A number of areas for research exist for further developing a chronic tympanic membrane perforation model. These areas include a perforation model in the presence of bacteria and eustachian tube dysfunction. Understanding the molecular and genetic mechanisms of chronic otitis media and potential treatments will also be useful.

Abstract
BACKGROUND The goal of this study was to evaluate the prevalence of chronic tympanic membrane perforation in the adult population. MATERIALS AND METHOD The study population included 1,000 subjects (453 males, 547 females) aged 18-93 years. In addition to interview data, ear examinations were performed. RESULTS There were eight subjects with unilateral chronic tympanic membrane perforation and a single subject with a bilateral perforation. The age adjusted prevalence of chronic tympanic membrane perforation was 0.45% (95% confidence interval: 0.03-0.87). Eight out of nine subjects disliked tympanoplasty. CONCLUSION The high proportion of subjects with chronic tympanic membrane perforations who do not want to be operated suggests that there is a considerable need for novel therapeutic procedures.
