Opis:: Objective: The aim was to determine the clinical characteristics and analysis of surgical treatment of patients with glomus tympanicum hospitalized in the Department of Otorhinolaryngology. Material and methods: Between 2000 and 2015, 27 patients were hospitalized. Age ranged 28-79 years old. The study analyzed data from the clinical examination and the type of surgical technique. Results: The most common symptoms were tinnitus and hearing loss. Resection of the tumor was performed by anterior tympanotomy in 3 (11,1 %), CWU mastoidectomy in 21 (77,8 %), CWD mastoidectomy in 1 (3,7 %), lateral petrosectomy in 2 (7,4 %) patients. Conclusion: Glomus tympanicum have a quite characteristic clinical picture with dominant symptoms of tinnitus, hearing loss and reddening of the tympanic membrane in otoscopic examination. This type of tumors require surgical treatment. Surgical access depends on the size of the tumor in the tympanic cavity. Most of these tumors can be removed using antromastoidectomy, with posterior tympanotomy and hypotympanotomy.

Opis:: Chronic suppurative otitis media (CSOM) refers to the middle ear inflammation which is clinically characterized by the discharging ear, hearing deficit, fever and otalgia. Although a clinical diagnosis, imaging is imperative to rule out associated complications which apart from causing hearing deficit, may prove fatal at times. Both high resolution computed tomography (HRCT) and MRI are helpful in evaluating middle ear pathologies, usage being indication specific. Due to its excellent spatial resolution, HRCT is invaluable in assessment of chronically discharging ears, especially to look for bone erosion and the integrity of the ossicles. Due to its better spatial resolution, HRCT is preferred in suspected intra temporal complications whereas MRI is more useful in evaluating intracranial extension.

Opis:: This manuscript intends to review types, pathogenesis, associated risk factors, and potential methods of prevention and treatment of the retraction pockets in adults and children. The importance of retraction pockets (RP) lies in loss of original histological and anatomical structure which is associated with development of ossicular chain erosion, cholesteatoma formation and potentially life threatening complications of cholesteatoma. The trans-mucosal exchange each gas in the middle ear (ME) is towards equalizing its partial pressures with the partial pressure in the environment. MEs that have abnormalities in the volume and ventilation pathways in the epitympanic may be more susceptible to retraction pockets. Sustained pressure differences and/or inflammation leads to destruction of collagen fibers in the lamina propria. Inflammatory mediators and cytokines lead to release of collagenases result in viscoelastic properties of the lamina propria. The process of changes in the tympanic membrane structure may evolve to the cholesteatoma formation. There are many different staging systems that clinicians prioritize in their decision making in the management of RP. The authors discuss the management possibilities in different clinical situations: RP without and with ongoing or intermittent evidence of Eustachian Tube Dysfunction (ETD), presence of adenoid hypertrophy or re-growth of adenoids, presence or absence of effusion, invisible depth of RP without effusion. invisible depth of RP with effusion, ongoing RP after VT insertion, and finally suspicion of cholesteatoma in a deep RP with ME effusion. A decision algorithm regarding the management of TM retraction and retraction pockets is provided.

Opis:: Introduction: Knowledge about the physiology of a healthy middle ear is essential for understanding the activity and mechanics of the ear as well as the basics of ossiculoplasty. Trauma of the epithelial lining of the tympanic cavity as well as the ossicular chain may be the result of chronic inflammation and surgery. Depending on the observed changes of the middle ear lining, there are several types of distinguished chronic inflammatory changes: simple, with cholesteatoma, with the formation of inflammatory granulation tissue, in course of specific diseases. Purpose: The aim of the article is presentation of the microstructure and vasculature of the ossicular chain in the Scanning Electron Microscope. Particular attention is drawn to the anatomical aspects of the structure and connections of auditory ossicles as vital elements for reconstruction of the conduction system of the middle ear. Material and method: The analysis covered auditory ossicles standardly removed in accordance with the methodology of the investigated surgical procedures. The preparations were evaluated in a scanning electron microscope. Results: The exposure of bone surface promotes deep erosion. The advanced process of destruction of bone surface in the case of chronic otitis media correlates with a significant degree of damage to both the lining covering the auditory ossicles and that surrounding articular surfaces. Conclusions: (1) The ossicles in the image of the Scanning Electron Microscope are covered with lining. It passes from the surface of the ossicles to the vascular bundles, forming vascular sheaths; (2) Damage to lining continuity on the surface of the auditory ossicles promotes the rapid destruction of bone tissue in the inflammatory process; (3) The dimensions of the individual ossicles are respectively: malleus – 8.36 +/- 0.01, incus – 8.14 +/- 0.0, stapes – 3.23 +/- 0.01 mm. Behavior of the anatomical length of ossicular chain during tympanoplasty appears to be essential to maintaining adequate vibration amplitude of the conductive system of the middle ear.

Opis:: Tympanostomy tube insertion and tympanic membrane incision are two the most frequently performed surgical procedures in otolaryngology, especially in children. The tympanic membrane incision - paracentesis, or myringotomy – is an incision of the tympanic membrane for diagnostic purposes or to allow drainage of pathological secretion from the tympanic cavity. Tympanostomy tube insertion involves incision made in the tympanic membrane and insertion of a ventilation tube (various types and for various periods of time) to improve hearing and aeration of the tympanic cavity. Procedures are performed through the ear canal (transcanal approach), under local or general anesthesia. Complications may occur in some cases of paracentesis and tympanostomy tube insertion.

Opis:: The development of imaging methods that has taken place in the last twenty years and the increase in the availability of highresolution CT of temporal bones makes it possible to analyze the complex anatomy of the interior of temporal bone in detail with even greater accuracy. Simultaneous advances in middle ear surgery require from the surgeon to be proficient in interpreting imaging studies. This approach creates the possibility of selecting the treatment method individually for each patient and may also contribute to reducing the risk of complications. The article presents a description of CT examination technique with a historical outline, as well as the interpretation of the CT scan of temporal bones along with a description of the anatomical structures, with particular emphasis on the structures of the middle ear. In addition, anatomical variants that may be encountered by a person viewing images obtained with this method are presented.

Opis:: Introduction: Paragangliomas are rare neuroendocrine tumors. Most frequently located at the carotid body, jugular foramen and vagus nerve. They are hypervascular, slow-growing and generally benign, but they can cause significant complications due to the associated mass effect and compression or even erosion of the local structures. Aim: The aim of this study is to analyze the directions of spreading and correlation with the clinical characteristics of these tumors located in the jugular foramen area. Materials and methods: Analysis of the clinical presentation and treatment of 6 patients (4 women and 2 men), aged 36 to 72, who underwent surgery in November 2022 at the Department of Otorhinolaryngology of the Medical University of Warsaw. Particular attention was paid to the relationship between tumor morphology, clinical manifestations and course of treatment. Results: Four out of six patients developed hypoacusis, three out of six suffered from vertigo, tinnitus and pain. One patient had a tumor of the bulb of the jugular vein spreading to the parapharyngeal space. In two patients, the tumor occupied the tympanic cavity. In one patient, it grew into the posterior cranial fossa. Sigmoid sinus involvement was found in two cases. In the most advanced case, the tumor involved the internal carotid artery, internal jugular vein, sigmoid sinus, and posterior cranial fossa. In five patients, the tumor involved the bulb of the internal jugular vein, but in different parts. The direction of tumor growth may be a result of the original location of the paraganglionic body in relation to the structures of the jugular foramen. Conclusions: The clinical manifestations of the described patients shows the diversity of paragangliomas development. Determining and predicting the direction of growth may play an important role in planning treatment, especially surgical. The development of these tumors requires more research to determine exactly where they form, as well as the potential risk of a disease-causing event.
