Abstract
Biomaterials play an integral role in treatment of external auditory canal (EAC) diseases. Regarding the special anatomic structure and physiological characteristics of EAC, careful selection of applicable biomaterials was essential step towards effective management of EAC conditions. The bioactive materials can provide reasonable biocompatibility, reduce risk of host pro-inflammatory response and immune rejection, and promote the healing process. In therapeutic procedure, biomaterials were employed for covering or packing the wound, protection of the damaged tissue, and maintaining of normal structures and functions of the EAC. Therefore, understanding and application of biomaterials was key to obtaining great rehabilitation in therapy of EAC diseases. In clinical practice, biomaterials were recognized as an important part in the treatment of different EAC diseases. The choice of biomaterials was distinct according to the requirements of various diseases. As a result, awareness of property regarding different biomaterials was fundamental for appropriate selection of therapeutic substances in different EAC diseases. In this review, we firstly introduced the characteristics of EAC structures and physiology, and EAC pathologies were summarized secondarily. From the viewpoint of biomaterials, the different materials applied to individual diseases were outlined in categories. Besides, the underlying future of therapeutic EAC biomaterials was discussed.

Abstract
OBJECTIVES The aims of our study were to investigate the clinical and audiometric outcome of the surgical treatment of postinflammatory medial meatal fibrosis (PIMMF) and to review the histopathologic changes in the specimens of the fibrotic plug, in order to try to shed light on the pathogenesis of the disease. MATERIALS AND METHODS The clinical records and the histopathologic specimens of all patients who underwent tympanomeatoplasty for PIMMF at the ENT Clinic of the University of Erlangen between 2006 and 2020 were evaluated retrospectively. RESULTS Thirty-four patients (41 primary surgical procedures) made up our study cohort. Of this, 28 cases were managed by means of meatoplasty and 13 cases with tympanomeatoplasty. The mean preoperative air-bone gap (ABG) was 27.8 dB (10-44 dB). Postoperative ABG was significantly improved compared to preoperative values at both short- and long-term follow-ups (P < .001 for both). No significant difference was noted between short-term and long-term ABG (P = .240). An ABG ≤20 dB was achieved in 65.8% of patients (short term) and 50% (long term). The overall rate of revision surgery for restenosis was 29.3% (12/41). Histopathologic reevaluation of the fibrotic plugs revealed a mosaic of patterns with frequent occurrence of secondary cholesteatoma-like lesions and keloid-like tissue changes. Lichenoid submucosal inflammation and increased ectopic ceruminous gland lobules were seen less frequently. DISCUSSION The moderate long-term outcome of surgical management and the identification of histologic changes with therapeutic implications might pave the way for alternative nonsurgical treatment options.

Abstract
OBJECTIVE To evaluate short- and long-term hearing results of surgery for acquired atresia of the external auditory canal (EAC) in a large patient cohort and to define preoperative audiometric conditions useful for patient counseling. STUDY DESIGN Retrospective cohort study. SETTING Academic tertiary referral center. PATIENTS Seventy-eight ears from 72 patients with postinflammatory acquired atresia of the EAC who underwent canal- and meatoplasty were included. Patients with involvement of the ossicular chain, (syndromic) external ear malformations, or congenital aural atresia were excluded. INTERVENTION Canal- and meatoplasty. MAIN OUTCOME MEASURES Mean pure-tone averages of thresholds at 0.5, 1, 2, and 3 kHz (PTA0.5,1,2,3) for air conduction (AC), bone conduction, and air-bone gap (ABG) were calculated preoperatively and at short-term (≤0.55 yr) and long-term follow-up (>0.55 yr). Additionally, the numbers of ears with a closed ABG ≤10 dB and ≤20 dB, and with Social hearing (defined as: AC PTA0.5,1,2,3 ≤35 dB) were assessed. RESULTS At short-term follow-up AC PTA0.5,1,2,3 improved by 18 dB. Social hearing was obtained in 81% of the ears. Postoperatively, 35% of the ears had a closed ABG ≤10 dB, 83% was closed ≤20 dB. During follow-up, significant deterioration of 5 to 7 dB occurred for AC thresholds at 0.25, 0.5, and 1 kHz. CONCLUSIONS Surgery for acquired atresia of the EAC is often beneficial. This study suggests overall advantageous surgery when the preoperative indication criteria ABG PTA0.5,1,2,3 >20 dB and AC PTA0.5,1,2,3 >35 dB are applied.

Abstract
Acquired atresia of the external acoustic meatus is a rare pathological condition characterized by obliteration of the medial part of the external acoustic canal by a soft fibrous plug. The present article presents an overview of a series of cases of acquired atresia and stenosis of the external acoustic meatus with the description of etiology, pathogenesis, and methods for the treatment of this condition. In the majority of the cases, atresia develops at the final stage of granulation external otitis with or without an accompanying dermatological pathology. Another common cause of the acquired atresia of the external acoustic meatus is the fracture of the temporal bone as well as extensive ear surgery, radiation therapy and a neoplasm in the auditory passage. The surgical strategy for the management of the acquired atresia and stenosis of the external acoustic meatus consists, besides the excision of the fibrous plug, of the application of the cutaneous flaps and/or transplants to cover the bare parts of the bone portion of the affected external canal. In spite of such treatment, the state of the external acoustic canal remains unstable, and a relapse of its atresia and stenosis can not be wholly excluded.

Abstract
Introduction
Acquired atresia of the external auditory canal is characterized by the formation of fibrous tissue in the medial part. The causes include chronic otitis externa, perforated chronic otitis media, postoperative or idiopathic healing problems. Acquired atresia presents with hearing loss and can be associated with otorrhea.
Objective
We analyzed the results of surgery after six months and two years by checking (1) pre- and postoperative hearing thresholds; (2) presence of otorrhea; and (3) whether a dry and patent ear canal is achieved.
Methods
We conducted this retrospective study at a tertiary referral center. In total, 27 ears underwent treatment with resection of the fibrotic plug followed by transplantation of a split-thickness skin graft covering the bare bone and tympanic membrane. When necessary, we combined this with a myringoplasty and a (meato-) canalplasty.
Results
Otorrhea was present in 59.3% of the patients initially and in 14.8% at six months and 11% at two years postoperative. A dry and patent ear canal was obtained in 55.6% after six months and in 89% of the patients after two years (
n
= 27). The pure tone average before surgery was 39.1 dBHL (SD = 20 dBHL), at six months 31.4 dBHL (SD = 16.4 dBHL), and at 24 months postop 30.9 dBHL (SD = 17.1 dBHL). We observed a statistically significant improvement of hearing in 63% of the patients at six months (
p
= 0.005) and in 65% after two years (
p
= 0.022).
Conclusions
Treatment of acquired atresia remains a challenge. Using the appropriate surgical technique, including skin-grafting and regular postoperative check-up, rendered excellent results regarding otorrhea and a moderate improvement of hearing was achieved in 65% of the patients after two years.

Abstract
Medial meatal fibrosis is a rare condition in which the medial portion of the external auditory canal is obliterated with fibrous tissue. We selected 4 cases of patients with medial meatal fibrosis with a history of recurrent otorrhea who underwent surgery during the years of 2012 and 2013, presenting the surgical results here. Physical examination showed an obliterated external auditory canal and conductive hypoacusis. All cases were solved using a split thickness skin graft from the thigh. The surgical principles that appear to correlate with a favorable outcome are the removal of all fibrous tissue and unhealthy skin, a wide canaloplasty and the use of a split thickness skin graft.

Abstract
AbstractObjectives:To evaluate the primary and long-term surgical outcomes of patients with postinflammatory medial meatal fibrosis.Methods:A retrospective study was conducted of 14 ears (in 12 patients) with postinflammatory medial meatal fibrosis managed surgically. Outcome measures were primary (i.e. less than six months) and long-term (i.e. greater than five years) closure of the air–bone gap, and the incidence of otorrhoea and restenosis.Results:At primary review, the mean air–bone gap ± standard deviation had decreased from 29.9 ± 11.6 dB to 12 ± 8.4 dB (p < 0.0006). Seven (50 per cent) ears had closure of the air–bone gap to within 10 dB. However, for the 9 ears receiving long-term review, the mean air–bone gap ± standard deviation increased to 19.3 ± 15.2 dB; there was no significant difference between this result and pre-operative values (p = 0.06). Of the 9 long-term review ears, 3 (33 per cent) showed closure of the air–bone gap to within 10 dB. Recurrent otorrhoea was the most common complication, occurring in 5 of the 9 long-term review ears (56 per cent); in addition, 3 (33 per cent) of these 9 ears developed restenosis.Conclusion:Over time, the success of surgery for postinflammatory medial meatal fibrosis diminishes. This was demonstrated in the present study by progressive post-operative hearing decline and a high prevalence of otorrhoea and restenosis.

Abstract
Objectives: I describe the clinical symptoms and signs of acquired atresia of the external auditory canal (EAC) and the technique used to manage it. Methods: Forty-one consecutive patients affected by acquired atresia of the EAC were assessed by otoscopy, pure tone audiometry, computed tomography, and traditional and echo-planar diffusion-weighted magnetic resonance imaging. The anatomic and functional hearing results were evaluated. Results: At surgery for acquired atresia of the EAC, an EAC cholesteatoma was found in 3 of the 41 patients. Twenty-three of the 41 patients were followed for at least 5 years. Recurrence was seen in 9 of the 25 ears (36%) over the entire period of observation. Twenty-one, 23, and 22 of the patients had a normal or nearly normal contour and size of the ear canal at 6 months, 1 year, and 5 years, respectively. The results were similar for the air-bone gap. Conclusions: The main complication following surgery was recurrence. There was recurrence at 6 months in 4 patients (16%). Recurrence was seen in 12% of the cases at the 5-year follow-up. Similar findings were clear on evaluation of the hearing results. This result demonstrates that the surgical procedure, even when performed correctly, did not afford a stable, long-lasting outcome in a cohort of patients.

Abstract
OBJECTIVE External auditory canal cholesteatoma (EACC) is a rarity. Although there have been numerous case reports, there are only few systematic analyses of case series, and the pathogenesis of idiopathic EACC remains enigmatic. STUDY DESIGN In a tertiary referral center for a population of 1.5 million inhabitants, 34 patients with 35 EACC (13 idiopathic [1 bilateral] and 22 secondary) who were treated between 1994 and 2006 were included in the study. RESULTS EACC cardinal symptoms were longstanding otorrhea (65%) and dull otalgia (12%). Focal bone destruction in the external auditory canal with retained squamous debris and an intact tympanic membrane were characteristic. Only 27% of the patients showed conductive hearing loss exceeding 20 dB. Patients with idiopathic EACC had lesions typically located on the floor of the external auditory canal and were older, and the mean smoking intensity was also greater (p < 0.05) compared with patients with secondary EACC. The secondary lesions were assigned to categories (poststenotic [n = 6], postoperative [n = 6], and posttraumatic EACC [n = 4]) and rare categories (radiogenic [n = 2], postinflammatory [n = 1], and postobstructive EACC [n = 1]). In addition, we describe 2 patients with EACC secondary to the complete remission of a Langerhans cell histiocytosis of the external auditory canal. Thirty of 34 patients were treated surgically and became all free of recurrence, even after extensive disease. DISCUSSION For the development of idiopathic EACC, repeated microtrauma (e.g., microtrauma resulting from cotton-tipped applicator abuse or from hearing aids) and diminished microcirculation (e.g., from smoking) might be risk factors. A location other than in the inferior portion of the external auditory canal indicates a secondary form of the disease, as in the case of 2 patients with atypically located EACC after years of complete remission of Langerhans cell histiocytosis, which we consider as a new posttumorous category and specific late complication of this rare disease.

Abstract
AIM: To determine the impact of cirrhosis on trauma patients and define the factors predicting death.
METHODS: The data on patients admitted to the trauma center from January 2000-2005 were studied retrospectively. The clinical variables were recorded and compared to identify the factors differentiating cirrhotic trauma survivors from non survivors. Child's classification criteria were derived from the reviewed charts of cirrhotic trauma patients to evaluate their predictive value in cirrhotic trauma. Trauma registry was also used to generate a trauma control group by matching for age, sex, abbreviated injury score (AIS) over the same period of time. The outcome variables compared were mortality rate, time of ICU and hospital stay. Results were expressed as mean ± SD. These data were analyzed by SPSS.11.0 statistical software. Univariate analysis was performed to identify significant medical factors for survivor and non survivors subjected to chi-square test. Fisher's exact test and Student's t test were performed to determine the statistical difference between cirrhotic and control groups. P < 0.05 was considered statistically significant.
RESULTS: Poor prognosis of traum patients was associated with one or more of the following findings: ascitcs, hyperbilirubinemia (more than 2 mg/dL), hypoalbuminemia (less than 3.5 mg/dL), and prolonged prothrombin time (more than 12.5 seconds). Although Child's classification was used to predict the outcome in cirrhotic patients undergoing portacaval shunt procedures, no significant difference was found in mortality rate as a function of Child's classification.
CONCLUSION: Cirrhosis is associated with a higher mortality, a longer time of ICU and hospital stay of trauma patients. It seems that treatment of trauma patients with pre-existing severe liver disease is a challenge to surgeons.
