It is a known fact that bacterial or viral acute otitis media occurs more frequently in the winter months. Only a few older studies on seasonal differences in middle ear findings are available. These studies are based solely on tympanography, without correlation to intraoperative middle ear findings. This study addresses the question of whether seasonal differences can be found in the preoperative tympanogram and in the corresponding intraoperative findings in children with chronic middle ear problems.This retrospective study included patients who had undergone myringotomy with or without tympanostomy tube insertion at the Charité-Universitätsmedizin Berlin between January and December 2011. Corresponding to the catarrhal phases, winter months were defined as those from November to April; summer months from May to October. The preoperative tympanogram and the documented intraoperative middle ear finding were statistically analyzed for seasonal differences.A total of 654 ears from 206 male and 127 female patients with mean age 3.7 ± 2.5 years were analyzed. In the majority of cases, a type B tympanogram was found (n = 376; 57.5%), whereas the middle ear was filled with air in 19.1% of cases. No significant seasonal differences were found for either the intraoperative middle ear findings or the preoperative tympanograms (p 0.05).For children with a typical history of chronic otitis media without effusion and chronic tube ventilation dysfunction, myringotomy with or without tympanostomy tube insertion is indicated independently of the season. The results indicate that a wait-and-see approach with hope of improvement during the summer months is not rational.

Evidence-based medicine is an approach to medical treatment intended to optimise patient-oriented decision-making on the basis of empirically proven effectiveness. For this purpose, a classification system has been established to categorise studies - and hence therapy options - in respect of associated evidence according to defined criteria. The Eustachian tube connects the nasopharynx with the middle ear cavity. Its key function is to ensure middle ear ventilation. Compromised ventilation results in inflammatory middle ear disorders. Numerous evidence-based therapy options are available for the treatment of impaired middle ear ventilation and otitis media, the main therapeutic approach being antibiotic treatment. More recent procedures such as balloon dilation of the Eustachian tube have also shown initial success but must undergo further evaluation with regard to evidence. There is, as yet, no evidence for some of the other long-established procedures.Owing to a multitude of variables, the classification of evidence levels for various treatment approaches calls for highly diversified assessment. Numerous evidence-based studies are therefore necessary in order to evaluate the evidence pertaining to existing and future therapy solutions for impaired middle ear ventilation and otitis media. If this need is addressed, a wealth of implications can be expected for therapeutic approaches in the years to come.

Tympanostomy is the most frequently performed surgery procedure in Germany. It enables middle ear ventilation and discharge of secretion from the middle ear with immediate hearing improvement and avoidance of complications and long-term pathologies of the tympanic membrane and the tympanum. The economical importance is emphasized by the fact that about 300,000 myringotomies are performed yearly. The best type of middle ear drainage and ventilation should be chosen on a case-by-case basis. In this context, the various techniques like conventional myringotomy, laser-myringotomy, short-term and long-term tympanostomy tubes and indications, complications and their treatments are described.

Warthin tumors (cystadenolymphoma, cystadenoma lymphomatosum papilliferum) account for approximately 10-15 % of all benign salivary gland tumors and are bilateral in approximately 10-15 %, as well as extraparotideal in approximately 8 % of cases. Nasopharyngeal Warthin tumors are extremely rare; however they should be borne in mind as a consideration of differential diagnostics. Furthermore, parotid glands and cervical lymph nodes should be examined as associated synchronous or metachronous manifestations are possible. Palpation, sonography and other radiological imaging of the cervical region, if applicable, might be required.

Up to 80 % of children can develop otitis media with effusion (OME) between birth and school age. Responsible are longstanding impairments of tubal ventilation which are based primarily on mechanical or functional obstructions. A quarter of the subjects affected by OME show either recurrent episodes over 3 months or protracted clinical courses and in these children an extended diagnosis is required. Besides infection-related adenoid hypertrophy, the differential diagnosis should include ciliary dysfunction, chronic rhinosinusitis, craniofacial malformations, gastroesophageal reflux, tumors and cancer treatment in the nasopharynx and in particular allergies. Clinical and experimental studies have indicated that respiratory allergies promote both adenotonsillar hypertrophy as well as inflammatory alterations in the mucous membranes of the Eustachian tube and middle ear and can thus promote the formation and persistence of OME. Because of a sensitization rate of about 30% in the general population at the predilection age from 3-6 years (KiGGS study), standard diagnosis (e.g. otoscopy and audiometry) should be extended by allergy diagnostic testing, especially in cases of recurrent or prolonged courses of OME. The most common classes of medications used for childhood allergies are antihistamines and nasal steroids, which could optimize the standard treatment of OME.

Otitis media with effusion (OME) as the most common cause of hearing loss in childhood plays an important role in the follow-up after failed newborn hearing screening (NHS). The introduction of the NHS allows OME to be diagnosed and treated in the first months of life.In 715 children referred to the Department of Phoniatrics and Pedaudiology of the Ear, Nose, Throat University Hospital of Magdeburg during the period 2006-2010, the prevalence and therapy process of OME during follow-up could be determined.OME was diagnosed in 16 % of the patients. Spontaneous resolution was observed in 37 % of the cases, while 46 % of the children were treated surgically. A substantially increased risk for persistent OME was observed in children with craniofacial dysmorphia or cleft palate.Using NHS, OME can be diagnosed and treated early, thus, preventing potential problems in the linguistic, social and intellectual development of children.

Adenotonsillar hyperplasia is considered as a possible cause for two frequent ENT disorders in children: pediatric obstructive sleep apnea syndrome (OSAS) and otitis media with effusion (OME). The present study analyzes whether a link between pediatric OSAS and OME can also be presumed.Polysomnographic data of 186 children with suspected OSAS were correlated to middle ear ventilation assessed by tympanometry. Tympanograms were classified according to Jerger.In a Kruskal Wallis test, children with an apnea-hypopnea index 1 (exclusion of OSA by tight criteria), 1-5 or 5 (definitively pathological value) did not statistically significantly differ in the prevalence of normally ventilated ears and OME. Accordingly, the Mann-Whitney U test showed that children with normally ventilated ears did not have a statistically different apnea-hypopnea, apnea, hypopnea or snoring index or varying minimal oxygen saturation to children suffering from OME.In the present study, no link was detected between pediatric OSAS and OME.

The otologic diagnostic powder test with grape - sugar simple will be performed with a powder - blower. It permits a good differentiation between dry squamous epithelium and wet mucosa. In our opinion this test therefore is unrenouncable in microscopic differentiation between mucosa in central perforations on one hand and atrophic scars, retraction pockets or adhesive epithelium of the drum or complete atelectasis of the tympanic cavity on the other hand.

The treatment of MRSA (methocillin resistant staphylococcus aureus) colonized middle ear is difficult. According to the guidelines, a MRSA colonized Patient is not to be treated with systemic antibiotics. The topical treatment shows the problem of the ototoxicity of most of the used antiseptic as well as antibiotic substances.Selective literature review and consideration of the author's own clinical experience.Antibiotic treatment options include aequeous Tetracyclin drops, aequeous chloramphenicol drops and quinolon ear drops (unfortunately the MRSA is resistent mostly). Antiseptics without ototoxic effects are the Burow's solution, Povidone-iode, acetic acid solutions and aequeous dequalinium solutions.

Eustachian tube dysfunction plays a pivotal role in the pathogenesis of otitis media with effusion. Besides the lack of sufficient animal models to investigate the role of gastroesophageal reflux on Eustachian tube function, there is no reliable test that clinically allows the quantification of Eustachian tube function. Therefore, we established a Mongolian gerbil model to trace gastroesophageal reflux into the middle ear. In gerbils with traceable reflux, the refluxate reached the both middle ears through the Eustachian tubes in most cases.Clinical studies were performed to analyze the reproducibility of measuring the accuracy of modified tube manometry in healthy Caucasians.Tube manometry was found to be a reliable and reproducible tool for measuring Eustachian tube function.Both our animal model and the clinical application of tube manometry are likely to be useful for further experimental and clinical studies.

Malfunctions of the eustachian tube after Le Fort I osteotomies are rare. A 22-year-old woman was treated by Le Fort I osteotomy for maxillary retrognathism. Postoperatively she developed recurrent tubal malfunction and middle ear effusions on the left side, with no improvement after adenotomy, tonsillectomy, and grommet insertion. In consecutive computed tomography and magnetic resonance imaging scans, a forward dislocation of the left pterygoid hamulus was demonstrated. In addition, damage to the tensor veli palatini muscle was evident. Both postoperative sequelae appear to be responsible for the unilateral tubal dysfunction.

Today, 65 % of all infections are regarded as a consequence of local biofilms. In Otorhinolaryngology frequent diseases including chronic tonsillitis, chronic sinusitis, otitis media with effusion and cholesteatomas fulfill the clinical criteria of biofilm-associated diseases such as recalcitrant disease, inefficiently treated with long-term antibiotics. Apart from affecting a great proportion of our clinical spectrum, ENT-specialist frequently insert implants into ventilated area such as trachea, middle ear and paranasal sinuses, all susceptible for biofilm attachment. In short, relevant characteristics of biofilms and their development are summarized, clinical knowledge of otorhinolaryngologic diseases is presented and current and future therapeutic approaches are discussed.

Chronic tube dysfunction plays a major part in the development of chronic otitis media. Owing to the complex structure of the Eustachian tube, the development of successful therapeutic approaches to the treatment of tube function disorders is still difficult even today. The application of a gold tube wire (tube conductor) was reported in 1991, but no studies have yet been performed on the postoperative success rates achieved with tube conductors.In a retrospective study, the data relating to 125 patients who were operated on from 1996 to 1999 for treatment of different forms of chronic otitis media and also underwent transtympanic tube conductor implantation to improve tube ventilation disorder were evaluated. Data on pre- and postoperative tube function were available for 96 patients after a mean follow-up period of 18 months.All tube implantations were achieved without complications. Tube function normalized in 8 patients (8.3%), while the tube ventilation disorder remained unaffected in 88 patients (91.7%). A total of 23 (18.4%) tube conductors have so far been removed. The reasons for removal include persistent tube ventilation disorder, dislocation of the tube conductor in 7 patients (5.6%) and granulation around the tube wire in 7 cases (5.6%).The chronic tube ventilation disorder was improved by implantation of a tube conductor in only 8.3% of the patient population investigated. We are therefore of the opinion that this is not a suitable treatment for chronic tube ventilation disorders. The development of new, effective therapeutic approaches to the treatment of chronic tube ventilation disorders remains a priority.

In this case report an artificial disorder with symptoms of chronic otitis media and progressive hearing loss is described. This represents a rare case of Munchausen syndrome. The difficulties in diagnosis and therapy are shown by the development of the disease, produced by self damaging activities.

In the presence of persistent or recurrent otorrhea with or without hearing impairment, a chronic infection of the middle ear should be suspected. Otoscopy is performed to distinguish between the less serious central perforation of the tympanic membrane and the peripheral bone-eroding infection, cholesteatoma. The diagnosis is purely clinical. Prior to an operation, a hearing test, radiography of the mastoid air cells and treatment of any infection are a must. Central perforation of the tympanic membrane is a relative indication for surgery, while in the case of a cholesteatoma complete removal of the process is mandatory to avoid potentially serious complications. Reconstruction of the ossicles takes second place in importance to complete removal of the cholesteatoma. All patients with this condition--in particular children--should be kept under surveillance over the long term.

Otitis media with effusion (OME) may have adverse effects on children's cognitive, language, speech and psychosocial development. This has been demonstrated using several lines of research, the results of which, however, are not unequivocal. The question of how OME can interact with language, speech and cognitive development is also a subject of debate. According to the acoustic-phonetic theory, reduced perceptual ability during episodes of OME results in a degraded representation of subphonemic features of speech sounds, leading to speech delay. The mediated theory holds that fluctuant hearing loss endangers diffuse cognitive-linguistic effects, affecting speech perception and production.

The treatment results of symptomatic radiation therapy of the Eustachian tube in chronic otitis media had to be evaluated retrospectively.Between 1980 and 1997, 66 patients were referred for therapy. The median age was 58 years. In the clinical presentation, all the patients had a hearing impairment, 35 patients complained of pain, 21 had otorrhea. In their history, 20 patients indicated chronic recurrent infections. The complaints lasted for 4.7 years in the median, primary conservative (adstringentia, antibiotics) and surgical treatment (paracentesis, tympanic tubule, tympanoplastic) did not lead to lasting cure. In 40 of 66 patients, finally radiation therapy was done of both Eustachian tubes. With opposed fields and cobalt-60 photons a total dose of 6 Gy at single doses of 1 Gy, three times a week, was applied. Under the causes for exclusion of radiation therapy were non-acceptance of the patients (nine), prior radiation therapies (six) or spontaneous improvement after initial presentation in our department. The treatment results were evaluated by interviews of the patients and regular otorhinolaryngological examinations.There were no side effects noticed. 28 of 40 (70%) patients reported a significant improvement that could be verified by objective otorhinolaryngological examinations. In the group of 26 nonirradiated patients, 22 could be interviewed indicating in 16 cases (72%) that the complaints were unchanged and chronic otitis media was lasting. In a subgroup analysis concerning the duration of otitis media radiation therapy proved more effective in an acute and subacute stadium of disease of up to 5 years duration, while the patients resistant to radiation therapy were entirely in a chronic stage of disease exceeding 5 years duration.Radiation therapy is an effective tool for symptomatic improvement of the therapy-resistant chronic otitis media. A dose of 6 Gy seems to be sufficient to achieve an antiinflammatory effect. Radiotherapy should be applied earlier after initial conservative and surgical treatment.

There are very few communications on this pathologic entity, which is also called "postinflammatory medial meatal fibrosis" (PIMMF), its etiology and the adequate therapy. Apparently the cause is a chronic inflammation (or chronic ekzema) of the medial part of the external meatus or also a long-lasting otorrhea in chronic otitis media. The stratified epithelium of the eardrum and of the adjacent bony meatus is destroyed and replaced by fibrotic tissue. The lateral part of the auditory canal remains open and has the form of the finger of a glove, it may contain granulations, but often it is lined with a smooth stratified epithelium. A severe conductive hearing loss is the result of this anomaly.During the last 10 years we operated on 46 patients (52 ears) for this pathology: after retroauricular opening, which allows the best control of the anterior tympanomeatal angle, the fibrotic tissue was removed keeping the lamina propria intact. The bony canal was widened, if necessary. The eardrum and the bony canal were covered with split skin graft from the retroauricular region, then the canal filled with an antibiotic package for 3 weeks.Underneath the fibrotic tissue we detected 3 cholesteatomata of the annular region, so it is important to remember, that the atresia may also cover a dangerous pathology. 6 times a second operation was necessary, besides that, we observed 14 recurrencies. All other patients had a wide epithelialized ear canal, their conductive hearing loss disappeared, and the results were stable over several years. Bacteriological and histological examinations were not helpful to clear up the etiology of this disease.Surgery is the treatment of choice of the acquired atresia of the external meatus. We suppose that in these patients a individual disposition causes the formation of this excessive fibrosis, which has some similarity with keloid formation.

The most important principle in treating secretory otitis media (SOM) is ventilation of the tympanic cavity. CO2 laser myringotomy achieves this via a self-healing perforation whose diameter essentially determines the duration of transtympanic ventilation.In this study, laser myringotomy was performed with the CO2 laser otoscope Otoscan in a homogeneous patient collective comprising 81 children (159 ears) suffering from SOM. The tympanic intervention was combined with an adenoidectomy or a CO2 laser tonsillotomy and therefore performed under general insufflation anesthesia. In all ears, approximately 2 mm circular perforations were created in the lower anterior quadrants with a power of 12-15 W and a pulse duration of 180 ms.None of the children showed postoperative impairment of inner ear function. Otomicroscopic and videoendoscopic monitoring documented the healing process. The mean closure time was found to be 16.35 days (8-34 days). As a rule, an onion-skin-like membrane of keratinized material was seen in the former myringotomy perforations at the time of closure. At the follow-up 6 months later the laser myringotomy sites appeared normal and irritation-free. Two of the tympanic membranes (1.6%) examined showed atrophic scar formation, one (0.8%) a perforation with a diameter of 0.5 mm. In 19 ears (14.7%) there was a recurrence of SOM within the observation period.Laser myringotomy competes with ventilation tube insertion in the treatment of SOM. It may be an useful alternative in the surgical management of secretory otitis media.

Chronic otitis media with effusion is one of the most common diseases in childhood. The causes of otitis media are unclear as far as their importance is concerned.Extensive search in the German and Anglo-saxon literature with following presentation of the results.The original idea of a mechanical obstruction of the eustachian tube by the adenoids seems to be insufficient. Inflammatory mechanisms as a result of pathogenic germs in the middle ear fluid stand opposite to immunomodulating mechanisms as relevant causes of chronic otitis media with effusion. There are references which lead to the importance of allergic co-mechanisms individually. The controversial discussion of the pathophysiology of chronic otitis media with effusion is illustrated by the different opinions of optimal treatment modalities. Varying medical treatment opportunities exist while centrally the importance of the use of antibiotics is controversial. Based on the absence of long lasting effects of medical treatments, there are groups supporting a wait-and-see policy. Concerning the long-term effects of operative treatment, the importance of isolate tubes insertion in opposition to a combined treatment modality (adenotomy and tubes) is controversial. The actual debate focusses on adenotomy or adenotonsillectomy without operating the middle ear as treatment modality in patients with otitis media with effusion.Economic and social importance of this disease forces further investigations in pathogenesis and optimizing of medical and operative treatment modalities.

Laserotoscopes are suitable for low-pain outpatient surgery of otitis media with effusion (OME) under topical anesthesia. The myringotomy perforations should have a diameter greater than 2 mm to ventilate the middle ear for approximately 3 weeks.In this study, the clinical applicability of a prototype of an Er:YAG laserotoscope (Baasel Lasertechnik, Starnberg, Germany) was tested. Formalin-fixed human tympanic membranes yielded the parameters suitable for clinical application of an Er:YAG laserotoscope in patients. With a focussed laser beam (beam diameter 500 microns), one is able to achieve perforations of 50-micron diameter with one single laser pulse applying pulse energies of 70 mJ (energy density 36 J/cm2). The ablation rate, i.e., the tissue layer that is ablated per laser pulse, is 100 microns using pulse energies of 70 mJ. This means that formalin-fixed human tympanic membrane can be perforated with one single laser pulse.Ten patients with OME (otitis media with effusion) were treated under topical anesthesia of the tympanic membrane (8% tetracainbase in Isopropanol for 15 min) with focussed laser pulses (beam diameter 500 microns) with energies of 100 mJ (energy density 52 J/cm2). A sufficient perforation diameter of 2 mm could be achieved with an average of 15 juxtaposed laser applications. The enlargement of the perforations was made difficult by extruding middle ear secretions and slight bleeding of the tympanic membrane. Between laser applications, the target tissue had to be cleaned by suctioning using the operation microscope. The healing of the tympanic membrane was verified and compared in postoperative clinical follow-ups. With a perforation diameter of 2 mm, the Er:YAG laser myringotomies healed within 14 days. The used parameters did not generate side effects such as inner ear hearing loss.An effective, easy, and practical performance of laser myringotomy is not currently possible with the Er:YAG laserotoscope.

One of the main functions of the ciliated cells of the middle ear mucosa is the continuous drainage of fluids from the middle ear cavity to the Eustachian tube. Impaired mucociliary clearance is related to disturbed clearance of middle ear secretions and results in otitis media with effusion. The aim of this study was to evaluate the ciliary beat frequency (CBF) and the ultrastructure of cilia in young patients suffering from otitis media with effusion (OME).CBF and ciliary ultrastructure were studied in 36 patients with OME and 10 normal subjects without any history of middle ear effusion.The CBF was significantly decreased in the study group (6.59 Hz, +/- 1.83) compared to the controls (10.68 Hz, +/- 1.87) and the incidence of ultrastructural defects was higher than in controls. The most common defect were compound cilia, random orientation of the ciliary axes, and defects of the central microtubules. Defects of the dynein arms were not observed.

Aneurysms of the temporal part of the carotid artery are unusually rare. The literature contains only a few previous reports dealing with hemorrhage from such malformations. In the present case massive bleeding occurred from a right-sided intrapetrous aneurym after myringotomy, which was performed as treatment for bilateral secretory otitis media. Due to the absence of any specific symptoms and the masking effect of middle ear glue preoperative identification of the aneurysm was not possible. Subsequent angiography showed the large fusiform extension of the intrapetrous aneurysm as well as multiple intracranial aneurysms. Leakage from the aneurism was closed definitively with muscle, fascia lata and a gelatin-resorcin-formalin-glue (Cardial). In order to apply the tissue patch the hypotympanic site of the aneurism was exposed using a posterior otosurgical approach. Due to extensive intracranial collateralization to the vertebral arteries bleeding persisted even after ligation of both carotid arteries. Temporary cardiac asystole was then induced to allow safe closure of the aneurysm. Following surgery the patient sustained loss of hearing in her ear and a partial peripheral facial palsy.

First language acquisition depends on intermodal perception, especially auditive, tactile-kinesthetic, and partly visual in addition to sensomotoric integration. The influence of the vestibular function for a physiological language development is still unknown.A case history of a child with bilateral aplasia of all semicircular canals, normacusis in the right ear, and severe sensorineural hearing loss in the left (hearing aid supplied), without mental deficiency, allows us to draw initial conclusions.Logopedic diagnostics revealed only a mild articulation disorder (interdental sigmatism, inconstant gammacism) as a possible consequence of recurrent middle ear effusions since early childhood. Language development diagnostics did not demonstrate any significant norm deviation.In contrast to the statomotoric disorder, no evidence for a specific language impairment was found. Our report elucidates the importance of a selected diagnostic imaging (spiral CT and MIP MRI) in the phoniatric-ped-audiological field.
