    Opis:
    Objective: A pure tone audiomety analysis of patients with extracranial complications of chronic suppurative otitis media (ECCSOM). Material and methods: We retrospectively analyzed audiometric data performed before treatment from 63 patients with ECCSOM (56 single, 7 multiple complications) including groups of frequencies. Results: The greatest levels of hearing loss were noted for 6 and 8 kHz (79.0 and 75.7 dBHL) and for the frequency groups high tone average (76.1 dBHL). As regards the severity of hearing impairment in pure tone average the prevalence of complications was as follows: labyrinthitis (77.8±33.6 dBHL), facial palsy (57.1±14.3 dBHL), perilymphatic fistula (53.9±19.9 dBHL) and mastoiditis (42.2±9.5 dBHL) (p=0.023). Conclusions: Hearing loss in ECCSOM is dominated by mixed, high-tone, moderate type of hearing loss, most profound in labyrinthitis. In 11% of patients the complication causes total deafness.

    Opis:
    Introduction: Chronic otitis media is characterized by tympanic membrane perforation and conductive hearing loss. In the active form of this disease, there will also be periodic or permanent otorrhea. With a number of surgical techniques available depending on intraoperative findings, otosurgery is the treatment of choice in such cases, the extent of which depends on the type and extent of the pathological changes. Material and Method: We carried out an analysis of 79 patients with chronic otitis media undergoing surgery at the Department of Otolaryngology, Jagiellonian University Medical College in Kraków between 2005 and 2014. Total audiometry was used as a part of hearing assessment, before the surgery, 6 months after the surgery and in the distant 10-year observation period. In addition, each patient completed the questionnaire and was examined by an otolaryngologist. Results: The analysis included 79 patients operated on due to chronic otitis media. The mean bone conduction (for frequencies 500,1000 and 2000 Hz) before surgery was 31.8 dB, it did not differ significantly (p = 0.355) after 6 months after surgery (32.8 dB), while it significantly increased (p < 0.001) in a distant 10-year control of 43.4 dB. The mean air conduction (for frequencies 500, 1000 and 2000 Hz) before the procedure was 57.6 dB, it significantly improved in the early control by 50.5 dB, at p < 0.001. In long-term follow-up it increased again to 61.3 dB and was significantly different from the early postoperative period (p < 0.001). The mean air-bone gap for frequencies 500, 1000 and 2000 Hz before surgery was on average 26.4 dB, it was significantly (p < 0.001) reduced in the postoperative period by 17.6 dB. The level of air-bone gap remained at a similar level in distant control. Conclusions: (1) A completely preserved ossicular chain in the absence of active chronic otitis media is the best prognosis for stable hearing improvement over the years with normal inner ear function; (2) Reoperation worsens the long-term results of a hearing test compared to the first operation.

    Opis:
    Introduction: Chronic purulent cholesteatoma of the middle ear, as well as to a lesser extent chronic granulomatous otitis media, lead to destruction of bone structures within the middle ear space. The above process is controlled by the OPG/RANKL/RANK system. Aim: The aim of the study is a comparative analysis of surgical material obtained from patients with diagnosed chronić cholesteatoma and chronic otitis media with inflammatory granulation in the assessment of the Scanning Electron Microscope (SEM). Material and methods: An analysis of 140 patients operated on due to chronic otitis media was performed. Forty patients who had been diagnosed with chronic cholesteatoma of the middle ear and chronic granulomatous otitis media were selected for a detailed analysis in the SEM. The final study under SEM included 20 patients. Results: The regular structure of cholesteatoma depicted in the SEM concerned 5 patients. In the remaining 7 patients, the system was irregular and even chaotic. The lack of regularity can also be observed in the case of granulation tissue, which in the SEM image presented itself as an irregular tissue mass without detectable regularities. Conclusions: (1) The regular pattern of the cholesteatoma matrix cells observed in some patients with chronic cholesteatoma of the middle ear reduces the molecular permeability of inflammatory cytokines, concurrently limiting the destructive activity on bone structures; (2) the presence of inflammatory granulation tissue in the middle ear is accompanied by an influx of leukocytes: neutrophils and lymphocytes, which are the source of pro-inflammatory cytokines, the growth of which activates the processes leading to the damage of bone tissue and the development of inflammation; (3) no specimen of acquired cholesteatoma revealed the presence of commensal organisms from Demodex species on the surface of the exfoliated human epithelium.

    Opis:
    Introduction: Ossiculoplasty can be carried out in a number of ways, depending on the anatomical and functional conditions encountered during otosurgery and the experience of a given centre. The extent of damage to the ossicular chain determines the reconstruction method. Aim: The objective of the study was to analyse treatment effects in terms of postoperative hearing improvement in patients with chronic otitis media, with a particular emphasis on stapedial superstructure preservation. Material and method: The records of 294 consecutive patients undergoing their first ENT surgery due to chronic otitis media at the Department of Otolaryngology of Collegium Medicum, Jagiellonian University of Kraków in 2009–2013 were analysed. In order to assess the role of preserved stapedial superstructure, 96 patients were eligible for further analysis. Results: The analysis points to a significant hearing improvement after ossiculoplasty with the preserved stapedial superstructure as compared with the patients after footplate mobilisation. On the other hand, the research results point to significantly smaller hearing improvement in those patients, in whom only stapes was preserved, as compared with those, in whom a more extensive reconstruction of the ossicular chain was possible. Conclusions: The air-bone gap measured before otosurgery often fails to reflect the extent of abnormalities and cannot, therefore, be considered as the only prognostic factor for postoperative hearing improvement. Stapes preservation is crucial for hearing improvement after middle ear surgery.

    Opis:
    Introduction: Despite the recent advances in otosurgery diagnosis of cholesteatoma and qualification for surgery remains an issue in contemporary laryngology. In cases of cholesteatoma recidivism, it is of utmost importance to properly locate the pathology in the middle ear to plan surgical approach. Magnetic Resonance imaging in diffusion-weighted non-echoplanar sequences (non-EPI DWI) enables cholesteatoma detection as small as 2 mm and could potentially prevent unnecessary second-look surgery. Computed Tomography of the temporal bone allows precise visualization of bony structures and topographical landmarks of the middle ear. A fusion of both imaging modalities combines the advantages of these techniques. Material and methods: Five patients treated in the Department of Otolaryngology, the Medical University of Lodz for probable cholesteatoma recidivism were included in this study. A high-resolution CT scan of the temporal bone and an MRI scan including non-EPI sequences was obtained in all patients. A fusion of CT and MRI studies was conducted using OsirixMD software. Fist, CT studies were fused with MRI BFFE sequences, then non-EPI sequences were added. Finally, if the patient qualified for surgical treatment histopathological diagnosis was compared with MRI results. Results: CT scans were analyzed to establish the extent of previous surgical interventions and anatomical landmarks preservation. In all cases, MRI results were suspicious of cholesteatoma recidivism. Four cases were confirmed in postoperative histopathological evaluation, there was one false positive case when intraoperatively scar tissue was identified, which was later confirmed as connective tissue upon histopathological evaluation. Conclusions: CT and MRI fusion provides a helpful diagnostic tool in preparation for surgery in patients with suspected cholesteatoma recidivism.

    Opis:
    Introduction: The aim of the middle ear surgery is to eliminate abnormalities from the mucous, ensure the due airing of the postoperative cavity and reconstruct the sound-conducting system in the middle ear. Numerous reports can be found in literature on the changes to bone conduction as a consequence of middle ear surgery. Study objective: The aim of the work is to define the factors that affect bone conduction in the patients operated on due to the perforation of the tympanic membrane with the preserved and normal mobile ossicular chain. Material and method: A prospective analysis of patients operated on due to diseases of the middle ear in 2009–2012 was carried out. The cases of patients operated on for the first time due to chronic otitis media were taken into consideration. The analysis encompassed the patients who had undergone myringoplasty. The patients were divided into several groups taking into account the abnormalities of the mucous observed during otosurgery. Results: A significant improvement of bone conduction was observed in the patients with dry perforation, without other lesions in the middle ear. The appropriate pharmacological treatment before otosurgery in patients with permanent discharge from the ear resulted in significant bone conduction improvement. The elimination of granulation lesions turned out to be a positive factor for the future improvement of the function of the inner ear. Conclusions: The lack of abnormalities on the mucous of the middle ear (e.g. granulation,) and discharge has a positive impact on improvement of bone conduction after myringoplasty. Adhesions in the tympanic cavity, especially in the niche of the round window, have a negative impact on improvement of bone conduction in patients after myringoplasty.

    Opis:
    Objective: We reviewed functional outcomes of tympanoplasty. Study design: The results of tympanoplastic surgery are changing in time. We present late treatment outcomes among different types of tympanoplasty. Methods: Eighty-six patients who underwent tympanoplasty were enrolled in the study. The results of pure tone audiometry performed 7 days before, then at 3 months, 1 year, and 3 years after the surgery were assessed. Type II tympanoplasty involved implantation of a partial ossicular replacement prosthesis and type III tympanoplasty involved reconstruction with a total ossicular replacement prosthesis and the use of autogenous homogenous material. Statistical analysis was performed. Results: With all four types of tympanoplasty, hearing improvement was achieved at 3 months and 1 year after surgery based on the magnitude of the mean ABG reduction (p<0.001). In patients who underwent type I, type III, and type IV tympanoplasty, the ABG reduction at 3 years after surgery was maintained at the level reported at 3 months and 1 year after surgery (p<0.001). In patients who underwent type II tympanoplasty, however, the mean ABG value was increased at all tested frequencies (p<0.05). The mean ABG values reported 3 years after type II and type III tympanoplasty were similar. Conclusions: Based on the results over time, hearing improvement seems to be less durable after reconstruction with the partial ossicular replacement prosthesis procedure compared to the total ossicular replacement prosthesis procedure.

    Objective: The aim of the study was to evaluate risk factors influencing the results of tympanoplasties on the base of material taken from the Department of Otolaryngology and Laryngological Oncology Collegium Medicum of the Nicolaus Copernicus University in Bydgoszcz between 2004-2009. In this period, 98 operations were performed. The time from operations to hearing examination was 3 to 7 years, mean 5,43. Tympanoplastic operations were divided according to Tos classification. Measuring hearing results, tonal audiometry was done and mean air bone gap on four frequencies was assessed (500, 1000, 2000, 3000 Hz), according to AAO-HNS guidelines (1995). This parameter was compared between groups separated according to risk factors, that could potentially affect the results. Those risk factors were: disfunction of the Eustachian tube, location and size of the perforation of the tympanic membrane, damage of the ossicles, the state of the mastoid process, the number of operations, the presence of the cholesteatoma or granulating tissue, chronic otitis media in the opposite ear, smoking cigarettes, mastoidectomy, canal wall down technique. The results were analyzed using statistical test. Results: The most important risk factor affecting treatment results (besides discharge from the ear) is damage of the ossicles, especially the malleus and stapes. A properly performed operation ensures good hearing results irrespectively of the presence of cholesteatoma or granulating tissue, and also in case of reoperation. For all types of tympanoplasties neither the location, nor the size of perforation influence the hearing results in long-term observation.

    Wstęp: Nowotwory mające swoją etiologię w gruczołach ślinowych występują rzadko i stanowią ok. 3–10% wszystkich guzów w obrębie głowy i szyi. Materiał i metody: W latach 2006–2016 w Klinicznym Oddziale Chirurgii Czaszkowo-Szczękowo-Twarzowej Wojskowego Instytutu Medycznego w Warszawie z powodu nowotworów ślinianek przyusznych hospitalizowano i leczono 149 pacjentów. Podstawą do analizy były historie chorób pacjentów, wyniki badań histopatologicznych oraz protokoły zabiegów operacyjnych. Wyniki: W 126 przypadkach guzy były łagodne, natomiast w 26 guzy złośliwe. Analizując wyniki można stwierdzić, że nowotwory - zarówno łagodne, jak i złośliwe – częściej występowały u mężczyzn. Średni wiek całej grupy badanych wynosił 58,3 lat, dla zmian złośliwych – 65,5 lat, a dla zmian łagodnych był nieznacznie niższy i wynosił 56,9 lat. Wśród pacjentów objętych analizą szczyt zachorowalności przypadał na przedział wiekowy 60–69 lat. Ponadto zwraca uwagę, iż przedział ten był taki sam dla ogólnej liczby guzów, jak i nowotworów łagodnych, natomiast dla nowotworów złośliwych był nieznacznie wyższy i wynosił 70–79 lat. Z analizy zebranego materiału wynika, że guzy łagodne występowały znamiennie częściej, stanowiąc 84,56% wszystkich guzów. Najczęstszymi rozpoznaniami wśród nowotworów łagodnych były gruczolak wielopostaciowy (adenoma pleomorphicum) oraz gruczolak limfatyczny (adenolymphoma), które stanowiły łącznie 93,66%. Rezultaty badań wskazują, że wśród nowotworów złośliwych dominowały: gruczolakorak polimorficzny o niskiej złośliwości (polymorphous low-grade adenocarcinoma) występujący w 26,07% przypadków, gruczolakorak inaczej nieokreślony (adenocarcinoma NOS) oraz rak zrazikowokomórkowy (acinic cell carcinoma). Każdy z nich stanowił po 13,04% rozpoznań. Jak wynika z przeprowadzonej analizy najczęstszą metodą leczenia było leczenie chirurgiczne jako metoda stosowana samodzielnie. Wnioski: Uzyskane z retrospektywnej analizy dane korelują z piśmiennictwem krajowym i światowym.
