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.

overview
Opis:: Congenital cholesteatoma is a rare ear disorder. The most common presentation is a pearly and white mass, visible with an intact tympanic membrane in individuals with no previous history of ear discharge, ear surgery or perforation of tympanic membrane. Based on a careful overview of literature, authors of this article present: the most probable theories of the cause of development of congenital cholesteatoma, diagnostic criteria of congenital cholesteatoma, its most common clinical symptoms, preoperative studies, methods of surgical treatments and goals of postoperative proceedings. Furthermore, authors present a comparison of histological, molecular and clinical features of congenital and acquired cholesteatomas.

Tytuł:: Drainage or paracentesis
Autorzy:: Zielnik-Jurkiewicz, Beata

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:: 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.
