<b>Introduction:</b> The authors conducted this study to review the available resources and prepare an algorithmic approach to pre-transplantation sinonasal evaluation.</br></br> <b>Materials and methods:</b> The sources of data were PubMed, Cochrane databases, and Google Scholar. We searched the available database for English-language studies using the keywords rhinosinusitis, transplantation, post -transplant sinusitis. Studies of all designs were included.</br></br> <b>Results:</b> Thirty-five relevant studies were retrieved from a total of 182 articles. The review of references guided us to 5more publications.</br></br> <b>Discussion:</b> We have proposed an algorithmic approach to sinonasal evaluation before transplantation which can provide a brief but comprehensive assessment of the patients. The evaluation begins with a thorough history and physical examination, including nasal endoscopy with careful attention to objective evidence of inflammation. CT scan should not be considered in all of the cases.</br></br> <b>Conclusion:</b> We have suggested an algorithm to provide a comprehensive and cost-effective way for the evaluation of sinonasal diseases before planned immunosuppression in order to assist in reducing post-transplantation morbidity and mortality.

<b>Introduction:</b> Surgery is still the method of choice in chronic otitis media with cholesteatoma. Except for some specific clinical situations, classic canal wall up technique (CWU), remains a gold standard as a primary treatment in most departments. Unfortunately, the risk of recurrence in such an approach is estimated at 9 to even 70%. This fact prompts researchers to look for ways to reduce those unfavourable statistics. One of the recognized methods supporting the removal of cholesteatoma is the intraoperative use of mesna (sodium 2-mercaptoethanesulfonate). This synthetic sulphur compound disrupts disulfide bridges in polypeptide chains, thanks to which it facilitates matrix preparation.</br></br> <b>Aim:</b> To evaluate the effect of intraoperative use of mesna on the treatment outcomes in patients with chronic otitis media with cholesteatoma operated on by means of the canal wall up technique (CWU).</br></br> <b>Material and methods:</b> 459 surgical reports of patients with middle ear cholesteatoma were analyzed. In total, 52 adult patients with no history of previous ear surgery operated on by means of the CWU technique by the same experienced otosurgeon with all follow-up data available were included in the study. Twenty-six were operated on with the use of mesna (mesna group) and 26 by means of the classic CWU technique (control / no-mesna group). There were 28 women and 24 men with a mean age of 41 years.</br></br> <b>Main Outcome Measure(s):</b> Postoperative hearing results and cholesteatoma recidivism rate.</br></br> <b>Results:</b> Overall recidivism rate was 21.15 %. It was higher in the no-mesna (26.9%) than in the mesna group (15.4%) - although the outcomes were better in the mesna group, the difference was not statistically significant (P = 0.49715). Hearing gain was better in the mesna than in the no-mesna group (10 dB vs 7 dB), but the difference was not statistically significant (P = 0.20089).</br></br> <b>Conclusions:</b> Our preliminary results show that mesna reduces recidivism rates in patients with cholesteatoma. Further study with the analysis of a larger group of patients is needed to prove it statistically.

<b>Introduction:</b> The facial nerve (FN) follows a complex route in the temporal bone. Successful temporal bone surgery requires knowledge of its course which can be achieved using imaging methods such as computed tomography. This investigation aims to analyze the FN course in its mastoid portion and second genu and the frequency of its atypical course.</br></br> <b>Material and methods:</b> This is a retrospective study that enrolled 104 CT scans of temporal bones of patients followed up in the outpatient clinic of the Otorhinolaryngology Department of Dentistry Faculty of the Medical University of Warsaw between 2020 and 2022. FN courses were classified as straight, bulging, or letter "S"-like. Other parameters estimated: </br> • position of the second genu according to the prominence of the lateral semicircular canal (classified as lateral, medial, or middle) and its distance from a line adjacent to the lateral semicircular canal was measured;</br> • the distance between the short process of the incus and the outermost point of the second genu;</br> • the course of the mastoid portion of FN and the location of SG in comparison to the tympanic portion of n. VII. The course was later classified as lateral, medial, or middle.</br></br> <b>Results:</b> Among the 104 assessed temporal bones, the course of the mastoid portion of FN was classified as bulging in 47 cases (45.2%). Straight and letter "S"-like courses were present in 41 (39.4%) and 16 (15.4%) cases, respectively. Deviation of the second genu according to the prominence of the lateral semicircular canal was medial in 86 cases (82.7%), and middle in 4 cases (3.8%). In the rest, second genu was paramedian to the prominence of the later circular canal. The mean distance between the short process of the incus and the outermost point of SG was 4.9 mm (0.73 mm). The mastoid portion was located laterally, medially, and in the middle of the tympanic portion plane in, respectively, 4.8%, 83.7%, and 11.5%. The second genu was located laterally, medially, and in the middle of the tympanic portion plane in 1.9%, 73.1%, and 25%, respectively. In conclusion, seven temporal bones (6.7%) of five patients presented with a lateral displacement of FN in relation to the established anatomical landmarks.</br></br> <b>Conclusions:</b> Although the atypical course of FN, including the lateral displacement of the mastoid portion, is rare, screening for it is crucial before surgical exploration.

<br><b>Introduction:</b> The taxonomy of vocal fold lesions has been refined, and it serves as a common descriptive language for diagnosis, treatment algorithms, and reporting of outcomes. However, we observe rare cases when numerous pathologies overlap, resulting in an unclear and complicated clinical presentation of the glottis.</br> <br><b>Aim:</b> The aim of this paper is to present cases of overlapping etiopathological factors which poses a challenge when making a diagnosis and referring a patient for adequate treatment.</br> <br><b>Material and method:</b> The study presents different photographs of the glottis, including some unique and unusual images in which overlapping pathologies were captured. The photographs are accompanied by case descriptions, comments, and pathological analyses.</br> <br><b>Results:</b> Four selected photographs showed a bunch of exophytic growth lesions with foci of whitish plaques, covered by yellowish crusts, with thinned, reddened vocal folds presenting foci of leukoplakia. The study discussed possible causes of vocal folds edema, diffuse erythema, presence of crusts or exudate, whitish debris/plaques or development of leukoplakia, non-neoplastic ulceration, as well as injected and reddened mucous membrane. Chronic infectious laryngitis, idiopathic ulcerative laryngitis, and drug-induced laryngitis were also mentioned. The study also raised the issues concerning diabetics and patients treated with inhaled corticosteroids, including candidiasis and primary aspergillosis of the larynx.</br> <br><b>Conclusions:</b> To conclude, everyday clinical practice involves encountering cases of unclear onset and course, with complicated presentation of the glottis. Therefore, comprehensive history-taking and thorough investigation of systemic causes are of immense importance. Recommended management includes conducting the most meticulous differential diagnosis, implementing treatment for the most likely cause, and, whenever possible, refraining from biopsy in order to avoid permanent damage to vocal cords.</br>.

Chronic rhinosinusitis with nasal polyps (CRSwNP) has a significant impact on the well-being and social functions of the patient. The generalized inflammatory process with the formation of nasal polyps and excess eosinophils in the mucosa of the paranasal sinuses is called type 2 inflammation, which is mediated by Th2 lymphocytes – cells of the immune system responsible for chronic inflammatory processes. Today, we also know the key pro-inflammatory mediators against which new drugs have been developed, the so-called biological drugs, are produced in cell lines. In this document, we present currently available biologicals approved for the treatment of patients with T2-related chronic rhinosinusitis.

<b>Introduction:</b> The COVID-19 pandemic constituted a significant challenge for healthcare systems. Epidemiological restrictions led to deferral of healthcare and influenced the variety of symptoms reported by patients suffering from Sudden Sensorineural Hearing Loss.</br></br> <b>Aim:</b> The aim of the study was to compare the duration of treatment implementation and symptoms reported by patients suffering from SSNHL before and during the COVID-19 pandemic.</br></br> <b>Material and methods:</b> Patients admitted to the Military Institute of Medicine - National Research Institute for SSNHL treatment were included in a survey conducted between 01.10.2021-31.12.2021. Questions on symptoms reported, chronic conditions, timeframe between first symptoms and implementation of pharmacotherapy, and hyperbaric oxygen therapy were included in the survey. The results were compared with data obtained by the Team between 01.2017-12.2019.</br></br> <b>Results:</b> 34 patients (19 females, 15 males) of the average age of 46.3 who participated in the survey indicated a significantly delayed implementation of pharmacotherapy and hyperbaric oxygen therapy in comparison to population from before the pandemic (12.08 vs. 5.41 [days]; 17.5 vs. 8.29 [days]). The survey also showed differences in the number of symptoms reported.</br></br> <b>Discussion:</b> The differences in time of implementation of SSNHL treatment could have been related to pandemic restrictions which contributed to longer queueing for health benefits and fear of contact with health service. Differences in symptomatology point towards SARS-CoV-2 as a pathogenetic factor of SSNHL.</br></br> <b>Conclusions:</b> The COVID-19 pandemic significantly influenced the treatment of Sudden Sensorineural Hearing Loss. The study demonstrated a diverse symptomatology of SSNHL before and during the pandemic.

Objective: In tympanoplasty, surgical reconstruction of the tympanic membrane and ossicular chain is well-established; however, its hearing results still require improvement. Custom 3D printing of individualized ossicular prostheses seems to be an attractive solution for optimal prosthesis adjustment and better hearing results.

Aim: The aim was to design a custom ossicular prosthesis using a 3D printing method based on Cone-beam Computed Tomography (CBCT) scans and assess the acoustic conduction properties of such prosthesis.

Material and methods: A cadaver fresh frozen temporal bone was used. Based on CBCT images, a new incus prosthesis was designed and 3D printed. Next, canal wall-up tympanoplasty was performed. The intact ossicular chain and reconstructed 3D-printed prosthesis chain movements/vibrations were measured with Laser Doppler Vibrometer (LDV) system and analyzed in detail.

Results: The CBCT scans provided enough information about the anatomical structures. For frequencies 500 and 1000 Hz and 80 dB SPL sound intensity, collected velocities were higher for the intact ossicular chain than the 3D-printed ossicular prosthesis. The intensity thresholds for movement at 500 and 1000 Hz were lower in the intact ossicular chain than in the 3D-printed ossicular prosthesis. At 2000 Hz, there was the same intensity threshold value in the two measured circumstances.

Conclusion: It is possible to design a custom individually fitted ossicular prosthesis using a 3D printing method based on CBCT scans. The acoustic conduction properties of such 3D-printed prosthesis showed differences in movability pattern between the intact and reconstructed ossicular chain. More data are needed to analyze the acoustic properties of such designed prostheses in detail. The results of our experiment showed the 3D-printed prosthesis presents the potential to be an interesting option for conductive hearing loss treatment caused by chronic otitis media and the ossicular chain defects.

BackgroundThe Eustachian tube is a complex and inaccessible structure, which is responsible for the ventilation of the middle ear. The aim of the study was the assessment of an impact of chronic sinusitis on the auditory tube function. MethodsThe prospective analysis of 84 surgically treated chronic sinusitis patients was carried out. This study is based on preoperative results of impedance audiometry in correlation with the data from the medical history of chronic sinusitis, symptoms reported by the patients, results of Computered Tomography (CT) and the stage of inflammatory changes according to Lund and Mackay score. ResultsThe significant majority of patients of our study (65) had advanced auditory tube symptoms, while 4 patients suffered from symptoms significantly impacting daily life. In patients with chronic sinusitis the analysis demonstrated that tympanometry type B (12.67) and C (12.4) occured with significantly higher number of points of Lund-Mackay score than type A (9.2). In allergy sufferers type B of tympanometry was more often observed with characteristically bilaterally located inflammatory changes in maxillary and anterior ethmoid sinuses.ConclusionThe profile of chronic sinusitis patient in whom Eustachian Tube Dysfunction is more often observed, is as follows: Lund and Mackay score above 12pathological changes are bilaterally observed in maxillary and frontal ethmoid sinuses decrease of nasal patency nad postnasal dripAllergyoverusing alcohol and cigarettes, at least alcoholWorse result of Lund and Mackay score and the age of patients are 2 factors favoring the dysfunction of the Eustachian Tube.

Introduction: Mnire's disease is characterized by vertigo episodes with nausea and vomiting accompanied by aural symptoms. Diagnosis is based on clinical manifestation and sensorineural hearing loss confirmed in pure tone audiometry.

Aim: The purpose was to evaluate clinical features and audiological and vestibular tests in patients with definite Mnire's disease.

Material and methods: Seventy patients were enrolled in this study. The severity of the main clinical symptoms and audiological and vestibular tests were evaluated. The correlation between the clinical features and test results was evaluated.

Results: 14.29% of patients presented complete clinical characteristics as the first manifestation of Mnire's disease. 50% of patients suffered from isolated aural symptoms during the early stage of the disease. The subpopulation reporting hearing improvement after vertigo attack (28.57%) was characterized by shorter disease duration than the rest of the group. A statistically significant correlation between disease duration and pure tone average was found. 17.14% of patients reported Tumarkin drop attacks in their past medical history. Neither disease duration nor functional level scale was different in these patients compared to other patients.

Conclusions: Mnire's disease is often characterized by isolated aural symptoms or incomplete clinical manifestation during the early stage of the disease. The correlation between disease duration and pure tone average confirms that endolymphatic hydrops evolution causes hearing loss. A patient's quality of life is a fundamental aspect of clinical assessment. No significant correlation between disease duration and functional level scale was found. Thus Mnire's disease should be considered an individually variable and dynamic phenomenon.
