Abstract
Tympanic membrane perforation is a common condition in clinical otolaryngology. Although some eardrum patients can self-heal, a long period of non-healing perforation leads to persistent otitis media, conductive deafness, and poor quality of life. Tympanic membrane repair with autologous materials requires a second incision, and the sampling site may get infected. It is challenging to repair tympanic membranes while maintaining high functionality, safety, affordability, and aesthetics. 3D bioprinting can be used to fabricate tissue patches with materials, factors, and cells in a design manner. This paper reviews 3D printing technology that is being used widely in recent years to construct eardrum stents and the utilized applied materials for tympanic membrane repair. The paper begins with an introduction of the physiological structure of the tympanic membrane, briefly reviews the current clinical method thereafter, highlights the recent 3D printing-related strategies in tympanic membrane repair, describes the materials and cells that might play an important role in 3D printing, and finally provides a perspective of this field.

Abstract
BACKGROUND The aim of this study was to evaluate the effects of repairment of traumatic tympanic membrane perforation (TTMP) with cigarette paper patch (CPP) on perforation closure and hearing functions. METHODS A retrospective evaluation was made of 67 ears of 61 patients diagnosed with TTMP and treated with CPP in our clinic between January 2015 and 2019. In the classification of TTMP size, the entire tympanic membrane was evaluated as 100%, perforation of <25% was considered small, perforation of between 25% and 50% was considered medium and perforation of ≥50% was considered large. Audiological examination was performed before and at 3 months after the CPP procedure. Air conduction (AC) and bone conduction (BC) pure tone averages (PTAs) and air-bone gap (ABG) at 0.5, 1, 2, and 4 khz frequencies were compared. RESULTS Perforations were small in 20 (29.9%) of 67 ears, medium in 27 (40.2%), and large in 20 ears (29.9%). AC PTA before CPP was found to be 28.26±5.63 dB hearing level (HL), BC PTA was 8.80±4.35 dB HL and ABG was 19.26±5.80 dB HL. After CPP, the AC PTA was found to be 11.90±6.59 dB HL, BC PTA was 8.29±4.05 dB HL, and ABG was 14.10±4.66 dB HL. TTMP was determined to have improved in 61 ears (91%) in the 1st month after CPP application. There was no statistically significant difference between perforation size and improvement rates (p>0.05). AC PTA values after CPP application were determined to be significantly lower than AC PTA values before CPP application at 0.5, 1, 2, and 4 khz (p<0.001). The ABG values measured at 0.5 khz after CPP were significantly higher than the values measured at 2 khz. and 4 khz. (p<0.001, p<0.001, respectively). The amount of decrease in PTA value after CPP was found to be significantly greater at 0.5 khz than at 2 khz and 4 khz (p<0.001, p<0.001, respectively). CONCLUSION In the treatment of TTMP, early application of CPP is an effective treatment method in terms of both perforation closure and hearing gain.

To patch or not to patch acute isolated traumatic tympanic membrane perforations: a case series and systematic literature review. Eur Arch Otorhinolaryngol 2021; 279:4313-4323. [PMID: 34817658 DOI: 10.1007/s00405-021-07185-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Accepted: 11/15/2021] [Indexed: 11/28/2022]
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.

Laryngoscope 2020; 131:392-400. [PMID: 33176008 DOI: 10.1002/lary.28914] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2020] [Revised: 06/01/2020] [Accepted: 06/12/2020] [Indexed: 11/07/2022]
Abstract
OBJECTIVES Nonautologous graft materials may solve several dilemmas in tympanoplasty by obviating the need for graft harvest, facilitating consistent wound healing, and permitting graft placement in the clinical setting. Prior studies of nonautologous grafts in humans have shown variable outcomes. In this systematic review, we aim to 1) summarize clinical outcomes and 2) discuss limitations in the literature regarding nonautologous grafts for tympanoplasty in humans. METHODS A literature review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. The study size, etiology and duration of perforation, type of nonautologous graft, and postoperative closure rate were assessed. RESULTS The PRISMA approach yielded 61 articles, including 3,247 ears that met inclusion criteria. Studies evaluated nonautologous grafts including paper patch, gelatin sponge, growth factors, porcine small-intestinal submucosa, among others. Traumatic perforations (62.3%) were most commonly studied, whereas postinfectious perforations (31.9%) and other etiologies (5.8%) comprised a minority of cases. Acute perforations of <8 weeks duration constituted just over half of all treated ears. Overall closure rate was 82.1%, with significantly higher closure rates in acute (89.9%) versus chronic perforations (64.9%, P < .01), regardless of material. A median postoperative air-bone gap of 5.6 dB was found in the 23% of studies reporting this metric. CONCLUSIONS The majority of publications reviewing nonautologous materials in tympanoplasty evaluate acute or traumatic perforations, and few rigorously report hearing outcomes. Given available data, porcine submucosa and basic fibroblast growth factor may hold promise for chronic perforation closure. Future studies should report closure rates and hearing outcomes in perforations >8 weeks duration. Laryngoscope, 131:392-400, 2021.

Abstract
BACKGROUND Untreated traumatic tympanic membrane perforations (TMPs) may lead to permanent perforations and hearing loss. There are many materials that have been previously used for repairing the TMPs. AIMS AND OBJECTIVES The purpose of this study is to evaluate the clinical and histological effects of Vivosorb (Vv) and Epifilm on healing of TMPs in a rat model. MATERIAL AND METHODS The posterior-inferior quadrant of the tympanic membranes (TMs) in right ears of 14 rats was perforated using a 20-g needle and then the animals were randomly divided into 2 equal groups (n = 7). The perforated right TMs were treated with either Vv (Vv group) or Epifilm (Ep group). The left TMs of 7 rats were perforated in same way and allowed to close spontaneously without any topical material applications (spontaneous closure group as sham control, SC). The left tympanic membranes of the other 7 rats were not perforated and used as normal controls (NC group). On postoperative 15th day, tympanic bullas were extracted from killed rats and examined morphometrically and histopathologically. RESULTS Perforation closure rate was 85.7% (6/7) in both Vv and SC groups. Perforations of Ep group closed in 7/7 (100%) ears. The thicknesses of the perforated membranes were increased in SC and especially Vv groups. Also, connective tissue fibrosis, blood clots, and epithelial degenerations were detected in SC and Vv groups. The mean fibroblastic reaction scores of Vv, Ep, and SC groups were 2.14(+), 0.57(+), and 1.71(+) respectively, on comparison with NC group. The mean neovascularization score was 1.42(+) in Vv group, 0.14(+) in Ep group, and 0.57(+) in SC group. CONCLUSION AND SIGNIFICANCE Vivosorb and especially Epifilm can improve the healing process in traumatic TMPs and additionally, Epifilm might be more preferred for the treatment of TMPs because of causing lesser fibrosis.

Abstract
BACKGROUND Traumatic tympanic membrane perforation (TTMP) is usually managed conservatively because most close spontaneously within a few months. Nevertheless, spontaneous closure of TTMP during long-term observation has not been well described in the literature. OBJECTIVES The present study investigated factors associated with spontaneous closure of TTMP, and the characteristics of cases exhibiting spontaneous closure following long-term observation. MATERIALS AND METHODS The medical records of 40 patients with TTMP who visited the authors' hospital were retrospectively reviewed. RESULTS Spontaneous closure was observed in 27 (67.5%) patients. The healing period was <2 weeks in 6 cases, <4 weeks in 9, <3 months in 5, <6 months in 3, and ≥6 months in 4. All four cases in which spontaneous closure took ≥6 months exhibited a sign of spontaneous closure at 6 months following injury. Perforation in contact with the malleus was associated with a lower frequency of spontaneous closure. CONCLUSIONS AND SIGNIFICANCE In TTMP, surgery should be considered in patients who exhibit perforation in contact with the malleus. However, it has also been suggested that long-term observation may be a viable treatment option when a sign of spontaneous closure is observed within 6 months following injury.
