Polish Translation and Validation of the SCHNOS (Standardized Cosmesis and Health Nasal Outcomes Survey) Questionnaire.

<b>Introduction:</b> Rhinoseptoplasty procedures are focused not only on the aesthetic but also on the functional aspects. Surgical outcomes have to be evaluated in each patient. To date, the Polish literature has lacked a tool facilitating simultaneous assessment of rhinoseptoplasty's impact on both the external appearance and functionality of the nose.<b>Aim:</b> The aim of this study was to translate, adapt, and validate the Polish version of the original SCHNOS (Standardized Cosmesis and Health Nasal Outcomes Survey) questionnaire as used for the assessment of the functional and aesthetic outcomes in patients after rhinoplasty.<b>Materials and methods:</b> A total of 31 subjects (N = 24 [77.4%] women and N = 7 men [22.6%]) aged 19 through 55 years (M = 31.32; SD = 8.50) participated in the study. The SCHNOS questionnaire was translated in accordance with international guidelines. The psychometric accuracy of translation was tested in native speakers of Polish. The authors measured the internal consistency, correlatability, and repeatability of the instrument to determine its validity. The data were subjected to statistical analysis.<b>Results:</b> The confirmatory factor analysis confirmed the two-factor structure of the scale. The satisfactory reliability amounted to 0.888 [95% CI: 0.804-0.940] for the SCHNOS-O and 0.883 [95% CI 0.795-0.937] for the SCHNOS-C scale. Differential accuracy was confirmed by AVE values of > 0.5 as well as by correlation of the results with the Rhinoplasty Outcome Evaluation (ROE) questionnaire scores.<b>Conclusions:</b> The SCHNOS questionnaire has been translated, adapted, and validated for use in the Polish-speaking population. The tool was found to be relevant and reliable.

Asymmetrical Lateral Crus Steal in Geometric Tip Reshaping.

A key component of a well-performed rhinoplasty is to obtain the proper, aesthetic shape of the nasal tip. Various surgical techniques have been developed to achieve this effect. In this work, the author wanted to focus not only on the satisfactory shape of the nose, but above all on its main role-functionality. In this article, the asymmetrical lateral crus steal (ALCS) technique is proposed, which in its assumption will enable narrowing, better defining and rotating of the nasal tip, and at the same time enhancing nasal patency. We present a retrospective analysis within the group of 267 patients who underwent primary open-approach rhinoplasty that included the ALCS technique. The mean follow-up time was 12 months. A total of 232 patients achieved very good postoperative results without observation of any serious complications related to breathing difficulties or asymmetry of the nasal tip shape. ALCS is a relatively simple surgical technique to perform. The use of the ALCS suture creates the possibility of proper profiling of the nasal tip while improving the respiratory functions of the nose.

Changes in Maxillary Sinus Volume and Mucosal Thickness Post Bimaxillary Advancement Procedures: A Retrospective Study.

Background: Bimaxillary surgery is an elemental procedure in the field of cranio-maxillofacial surgery. It allows for the correction of even the most challenging cases of maxillomandibular disorders, malocclusion, facial asymmetry, and disproportion. The osteotomies and maneuvers carried out during the procedure result in changes to the surrounding tissues, including the maxillary sinuses (MS). The aim of this study was to assess the change in the maxillary sinus volume and the thickness of the mucosa after maxillomandibular advancement (MMA) surgeries. Methods: A group of 25 patients who underwent MMA surgery were included in the study. Computed tomography (CT) of the head and neck region was performed 2 weeks preoperatively and 6 months postoperatively. Acquired Digital Imaging and Communications in Medicine (DICOM) files were analyzed using different software programs to calculate the medium MS mucosa thickness and MS volume. Results: A statistically significant reduction in MS volume was observed (p = 0.015). The change in the median thickness of the MS mucosa was not statistically significant. The median sella-nasion-A point angle (SNA angle) value of the group increased from 80.2 to 83.4 degrees. A weak negative correlation between the SNA delta and the MS volume delta was observed. Spearman's rank coefficient: (ρ s = -0.381, p = 0.060). Conclusions: The MMA surgery results in a reduction in the MS volume. The amount of forward movement of the maxilla may be correlated with the extent of the MS volume reduction.

Effectiveness of the piezoelectric knife as a tool for nasal beak reduction in patients with chronic rhinosinusitis - a pilot study.

AIM: The aim of this study was to evaluate the safety and efficacy of the piezoelectric knife as a new tool for frontal beak surgery in patients with chronic rhinosinusitis (CRS) both in terms of imaging and perception of symptoms' outcomes. MATERIALS AND METHODS: The study involved 28 patients with CRS who underwent endoscopic sinus surgery (ESS) using a piezoelectric knife in the frontal recess region. Assessment of sinus imaging and patients' quality of life (QoL) was performed before and after surgery with the Lund-Kennedy and Lund-Mackay systems and the 22-item Sino-Nasal Outcomes Test (SNOT-22). RESULTS: Median scores on the Lund-Kennedy and Lund-Mackay systems decreased within 24 weeks after surgery with piezo knife assistance by 4 and 5 points, respectively. QoL improved with SNOT-22 scores decreasing by 35.5 points. CONCLUSIONS: ESS with the piezoelectric knife used for frontal beak reduction turned out to be a safe procedure. In the studied group of patients, the improvement was observed in terms of imaging, patients' perceptions of symptoms, and QoL outcomes. Therefore, the piezoelectric knife might be a valuable supporting tool in ESS in patients with CRS, although further observation is needed.

Assessing the Effectiveness of Different Hyperbaric Oxygen Treatment Methods in Patients with Sudden Sensorineural Hearing Loss.

INTRODUCTION: Hyperbaric oxygen therapy (HBOT) is one of the treatment methods in patients with sudden sensorineural hearing loss (SSNHL). It is recommended as an elective treatment in patients undergoing steroid therapy. According to current scientific reports, HBOT should be implemented within two weeks after the first symptoms. However, as far as the profile of HBOT is concerned, there are no straightforward recommendations. METHODS: The data obtained from the medical records of 218 patients undergoing HBOT for SSNHL at the Military Institute of Medicine-National Research Institute were analyzed statistically for the impact of the duration and the delay in implementing HBOT on the end results of pure-tone audiometry (PTA). RESULTS: A statistically significant hearing improvement in patients undergoing more than 15 cycles of HBOT was detected at all frequencies except for 1500 Hz; in the group reporting for treatment with a delay of more than 10 days, hearing improvement was statistically unsignificant at frequencies of 1500, 3000, and 4000 Hz. CONCLUSIONS: The statistical analysis showed that the urgent onset of HBOT could be a significant factor in the therapy of SSNHL.

The Effect of Hospital-Based Liquid Diet and Commercial Formulas on Laboratory Parameters and Postoperative Complications in Patients with Head and Neck Cancer.

Background: Patients with head and neck cancer (HNC) are at high risk of malnutrition. The aim of this study was to compare the effect of polymeric formulas available commercially and a high-protein liquid diet prepared in the hospital on laboratory parameters and postoperative complications in patients undergoing surgery for HNC. Methods: This single-center retrospective study included 149 patients who underwent surgery for HNC between 2008 and 2017. The following data were collected: patient and tumor characteristics, postoperative complications, and laboratory parameters measured at baseline and after surgery, including creatinine, alanine transaminase (ALT), aspartate transaminase (AST), and blood glucose levels. Correlations between the duration of enteral nutrition and blood parameters were assessed. Results: After surgery, patients receiving commercial formulas had lower creatinine and blood glucose levels and higher ALT and ASP levels than those on the hospital-based diet. The longer duration of feeding with commercial formulas before surgery was associated with enhanced preoperative levels of ALT and ASP and with lower postoperative blood glucose. Patients on the hospital-based diet had a higher rate of postoperative complications than those receiving commercial formulas (16.1% vs. 3.3%). Conclusions: There were no clinically important differences in blood parameters among patients with HNC depending on the type of preparations used for enteral feeding. However, increased levels of liver enzymes in patients fed with commercial formulas were notable. The early initiation of enteral nutrition before surgery helped achieve normal blood glucose levels after surgery. The use of commercial preparations contributed to reducing the number and incidence of postoperative complications.

Off-label drugs in otolaryngological practice against the background of legal conditions of Polish legislation.

<b><br>Introduction:</b> 'Off-label drug use' refers to the administration of drugs for unapproved indications or age groups, a different dosage or other form of administration. Considering the legal issues, there clearly exists a need to implement rules that would regulate the use of pharmaceuticals outside the scope of a marketing authorisation. The brevity and diversity of Polish laws in the field of health care leads to many interpretative doubts associated with particular legal acts.</br> <b><br>Aim:</b> We aimed to present clinical examples from everyday practice of off-label drug use from the medical and legal perspectives, and to support it with relevant legal acts.</br> <b><br>Material and method:</b> Off-label drug use in various otolaryngology subspecialties - otology (mesna), laryngology (bevacizumab, cidofovir and botulinum toxin) and head and neck surgery (botulinum toxin) - are presented and discussed in detail.</br> <b><br>Results:</b> Fourteen Polish legal acts regarding off-label drug use and 4 from EU legislation are commented on. The algorithm of cascade of decision-making processes in off-label drug use is shown.</br> <b><br>Conclusions:</b> Off-label use of medicinal products is not prohibited in Poland or the EU; nevertheless, it is undeniable that the unclear legal situation regarding the use of medicinal products for nonregistered indications creates difficulties. To minimise a doctor's liability risk, obtaining the informed consent from the patient for such treatment is advisable.</br>.

Patogenesis of tinnitus in patients with post-COVID syndrome - preliminary report.

<b><br>Introduction:</b> Similarly to hearing loss and dizziness, tinnitus is a frequently reported complication of COVID-19 and remains the subject of numerous scientific reports. However, the exact impact of SARS-CoV-2 on the pathophysiology of tinnitus observed in post-COVID syndrome remains unclear. One suspected cause behind the development of vestibulocochlear symptoms is the inflammation of neural tissue triggered by SARS-CoV-2 infection.</br> <b><br>Aim:</b> The aim of this study was to analyze the results of Brainstem Auditory Evoked Potentials (BAEP) in the context of tinnitus development among patients diagnosed with post-COVID syndrome.</br> <b><br>Material and methods:</b> This retrospective study involved the analysis of BAEP test results of patients admitted to the Audiology Clinic of the Military Institute of Medicine at the National Research Institute and diagnosed with the post-COVID syndrome. The study compared the average latency values of waves I, II, III, IV, V, and intervals I-III, III-V, I-V. The statistical analysis of the obtained data was performed.</br> <b><br>Results:</b> Out of 18 patients (9 female, 9 male) with an average age of 54.22 years (9.65) diagnosed with post-COVID syndrome, tinnitus was identified in 5 individuals (27.78%). A statistically significant increase in wave V latency (5.98 vs. 5.63 [ms]; P < 0.05) and interval III-V (1.99 vs. 1.71 [ms]; P<0.05) was observed between the groups of patients with and without tinnitus.</br> <b><br>Discussion:</b> Study results analyzing BAEP changes in patients with post-COVID syndrome in the context of tinnitus are insufficient in current literature. The only available report linking post-COVID syndrome with sensorineural hearing loss demonstrated a statistically significant increase in latency values of waves III, V, and an increase in intervals I-III, III-V.</br> <b><br>Conclusions:</b> Tinnitus in patients suffering from post-COVID syndrome may be related to prolonged conduction of nerve impulses within the brainstem auditory pathway. Detailed pathophysiology of these changes requires further research.</br>.

Algorithms of follow-up in patients with head and neck cancer in relation to primary location and advancement. Consensus of Polish ENT Society Board and Head Neck Experts.

Summary: The algorithm of follow-up in patients with head and neck cancer (HNC) has been prepared by a board of Polish Head Neck and Oncology Experts. The aim of this research is to focus on the specificity of HNC monitoring, to review the current trends in follow-up, and to adapt the evidence-based medicine international standards to the capabilities of the local healthcare service. Materials and methods: The first methodological step was to categorize HNCs according to the estimated risk of failure after the adequate first-line treatment and according to the possibility of effective salvage treatment, resulting in improved overall survival. The final method used in this work was to prepare an authors' original monitoring algorithm for HNC groups with a high, moderate, and low risk of recurrence in combination with a high or low probability of using an effective salvage. Results: Four categories were established: Ia. low risk of recurrence + effective organ preservation feasible; Ib. low risk of recurrence + effective salvage feasible; II. moderate risk of recurrence + effective salvage feasible; III. high risk of recurrence + effective salvage feasible; and IV. high risk of recurrence + no effective salvage feasible. Follow-up visit consisting of 1. ENT examination + neck ultrasound, 2. imaging HN tests, 3. chest imaging, 4. blood tests, and 5. rehabilitation (speech and swallowing) was scheduled with a very different frequency, at the proposed monthly intervals, tailored to the needs of the group. The number of visits for individual groups varies from 1 to 8 in the first 2 years and from 1 to 17 in the entire 5-year monitoring period. Group IV has not been included in regular follow-up, visits on own initiative of the patient if symptomatic, or supportive care needs, having in mind that third-line therapy and immune checkpoint inhibitors are available. Conclusion: Universal monitoring algorithm for HNC four groups with a high, moderate, and low risk of recurrence after the adequate treatment in combination with a high or low probability of using an effective salvage is an innovative approach to redeploying system resources and ensuring maximum benefit for patients with HNC.

The characteristics of Polish patients with salivary gland tumors: a ten-year single-center experience.

OBJECTIVES: The study aims to provide insights into the characteristics of Polish patients with different salivary gland pathologies. MATERIALS AND METHODS: This is a retrospective study conducted at a single center, including patients who underwent surgery for salivary gland pathologies between 2012 and 2022. RESULTS: This study included 239 patients who underwent surgery for salivary gland tumors or inflammatory diseases. Malignant tumors were diagnosed in 9.8% of participants, while 64% had benign tumors and 21% suffered from inflammation. The occurrence of complications after surgery was relatively low, with 9.9% of participants experiencing slight facial weakness or mild dysfunction, and 3% experiencing complete paralysis of the facial nerves. Significant differences were observed between patients with cancers and those with benign tumors and inflammation in terms of age. Cancers were more common in females (67% vs. 33%) and predominantly localized in the parotid glands (95%). CONCLUSION: Benign tumors, such as Warthin's tumors and polymorphous adenoma, were predominantly found in the parotid glands of patients aged 39-72 years. On the other hand, inflammatory diseases were primarily localized within the submandibular glands of males aged 40-68 years. Additionally, the presence of a malignant tumor was associated with longer hospitalization periods related to surgery and a higher risk of severe complications. CLINICAL RELEVANCE: This study on Polish patients with salivary gland tumors provides valuable clinical insights that can aid in diagnosis, treatment planning, patient counseling, and further research in the field of oncology. It contributes to the overall understanding of salivary gland tumors, potentially benefiting both patients and healthcare providers.

The management of sudden sensorineural hearing loss during COVID-19 pandemic.

<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.

Health care system efficiency in otolaryngological surgeries during COVID-19 pandemic in years 2020-2021 compared to years 2018-2019: data from the Military Institute of Medicine in Warsaw.

<b>Introduction:</b> Coronavirus disease 19 (COVID-19) pandemic had a great impact on the health care system. This resulted not only from changes in the way medical facilities operated but also from the need to treat a huge number of patients. On the other hand, uninfected people feared visiting the doctor.</br></br> <b>Aim:</b> The aim of the study was to assess the impact of the COVID-19 pandemic on the diagnostics and treatment of patients with head and neck cancer.</br></br> <b>Materials and methods:</b> This retrospective study involved analysis of data of patients from a single hospital unit who underwent surgical procedures due to head and neck cancer during the COVID-19 pandemic in years 2020-2021 (pandemic group) compared to years 2018-2019 (pre-pandemic group).</br></br> <b>Results:</b> Patients in the pandemic group (n = 123) were older and were more likely to have grade 3 cancer than patients in the pre-pandemic group (n = 116). Cancer stages were similar in both groups. During the pandemic, time from the first outpatient visit to surgery was longer (median 1.6 vs. 0.8 months), while time to radiotherapy was shorter (median 50.5 vs. 63 days) than in the pre-pandemic period.</br></br> <b>Conclusion:</b> During the pandemic, patients had to wait slightly longer for surgery but not for radiotherapy when compared with the pre-pandemic period. Despite this, they did not have more advanced disease.

The Effect of Nasogastric Feeding after Surgery in Patients with Head and Neck Cancers - Retrospective Single Center Experience.

This study aimed to assess clinical factors that could predict the need for nasogastric feeding after surgery in patients with head and neck cancer (HNC) and evaluate the effect of tube feeding on selected laboratory parameters.This single-center retrospective study included 153 patients who underwent surgery for HNC. Data on patient and tumor characteristics were collected, along with laboratory measurements. Logistic regression was used to identify the predictors of the need for nasogastric feeding. Laboratory parameters were compared between patients who required nasogastric feeding vs those who did not.Nasogastric feeding was required in 90 patients (59%). Significant predictors of nasogastric feeding in HNC patients after surgery, which were revealed by univariate regression analysis, included low body mass index (odds ratio [OR] = 0.84), squamous cell carcinoma histology (OR = 8.05), T2 tumor stage (OR = 2.27), red blood cell count (M/µL) (OR = 0.44), hemoglobin levels (g/dL) (OR = 0.80), and mean corpuscular volume (fL) (OR = 1.10). Multivariate analysis showed that low BMI (OR = 0.87) and red blood cell count (M/µL) (OR = 0.32) were prognostic factors for nasogastric feeding. A significant percentage increase in white blood cell count from admission to discharge was noted in patients who required nasogastric feeding vs those who did not (p = 0.003).Determining factors that predict the need for nasogastric feeding in HNC patients after surgery may support more personalized treatment planning to optimize clinical outcomes.

Selected Immunohistochemical Assessment and Clinical Examinations in the Diagnosis of Palatine Tonsil Diseases.

INTRODUCTION: The palatine tonsils are secondary lymphoid organs where immune processes occur, influencing the development of a targeted cellular and humoral response. The diseased tonsils are subject to immunological imbalances, including the activity of pro-inflammatory and anti-inflammatory factors. This leads to the development of palatine tonsil diseases, such as palatine tonsillitis and palatine tonsillar hypertrophy. AIM: The main aim of the study was to evaluate the similarities and differences in the clinical and pathomorphological pictures of patients qualified for surgical treatment due to hypertrophy or inflammation of the palatine tonsils. The aim was achieved by demonstrating the relationship between the patient's medical history and physical examination and histopathological diagnosis of a given tonsillar disease, evaluating the usefulness of basic blood tests (leukocytosis, ASO, ESR, and CRP) in differential diagnosis, and assessing the immunohistochemical assessment of palatine tonsil tissue. MATERIAL AND METHODS: The tonsils were stained with the following antibodies: IL-1, IL-2, IL-6, IL-8 IL-10, and IL-37 and CD25, CD40, and CD69, taking into account the histological division of the studied lymphatic tissue (epithelial, subepithelial, follicular, follicular center, and interfollicular). Patients aged between 19 and 70 years with tonsillitis or clinical signs of tonsillar hypertrophy were qualified for tonsillectomy/UPPP. Seventy-two males (68.6%) and thirty-three females (31.4%) were enrolled in the study. Histopathological and immunohistochemical assessment was performed on 105 palatine tonsils. RESULTS: The diagnostic value of blood tests, including determination of ASO, ESR, CRP, and leukocyte level, proved to be a significant predictor of tonsil disease. In the pathomorphological assessment, 75% of the subjects who had simultaneously elevated ESR (>4.73) and leukocytosis (>6.96) and reduced ASO (<161.03) and CRP (<0.31) belonged to the tonsillitis group. The immunohistochemical assessment revealed a diverse profile of the markers tested depending on the diagnosed disease of the tonsils. The follicular center proved to be the region of palatine tonsil tissue for which the most statistically significant differences between the markers were found. Responses to CD-40 and IL-1 were observed in this region. The tissue of epithelial, follicular, and interfollicular regions each showed one statistically significant value for the studied chemokines and lymphokines. However, the lack of significant statistical differences for p < 0.05 between the study groups was only noted in the subepithelial region. It should be emphasized that for the data as a whole (calculated on the basis of the data for all regions together), no statistically significant differences were observed. CONCLUSION: In conclusion, the results obtained are indicative of the presence of a specific immunohistochemical profile for palatine tonsil diseases. Significant discrepancies have been found in the clinical and pathomorphological assessment of tonsils qualified for tonsillectomy. Therefore, these methods should be considered complementary. The patient's medical history and physical examination, depending on the adopted clinical or histopathological classification, show a variation in the distribution of features that are the basis for allocation to a particular group.

Concordance between Clinical and Pathological T and N Stages in Polish Patients with Head and Neck Cancers.

BACKGROUND: The TNM (tumor, node, metastasis) staging system is important for the successful treatment of head and neck cancers (HNCs). This study aimed to evaluate the concordance between clinical and pathological T and N stages in patients with HNCs in Poland. METHODS: In this single-center retrospective study, clinical and pathological TNM staging data on 203 patients undergoing surgical treatment for HNC between 2011 and 2018 were collected and compared. The study group was classified as underdiagnosed, overdiagnosed, or correctly diagnosed with HNC based on pathological TNM staging. The concordance between clinical and pathological staging was evaluated using the kappa coefficient. RESULTS: Clinical and pathological TNM staging showed concordance in 59.9% of patients for primary tumor (T) and in 79.3% of patients for lymph node (N) classifications. Moderate agreement between the clinical and pathological stages was shown for stage T, while substantial agreement was revealed for stage N. The size and extent of the tumor were underestimated or overestimated in 73 of the 182 patients (40.1%), while lymph node involvement was downstaged in 11 of the 53 patients (20.7%). CONCLUSIONS: The disparities between clinical and pathological staging of HNC demonstrate the need for standardization in physical and pathological examinations, as well as radiographic imaging.

Biologicals in the treatment of chronic rhinosinusitis with nasal polyps ­ position of the Polish Society of Otorhinolaryngologists ­Head and Neck Surgeons and the Polish Society of Allergology experts

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.

The Influence of Endodontic Lesions on The Clinical Evolution of Odontogenic Sinusitis-A Cohort Study.

Endodontic disease with formation of periapical lesions (PALs) is one of the most common causes of chronic odontogenic sinusitis (ODS). It requires close collaboration between otolaryngologists and dentists, but the best sequence of management is still unknown. The aim of the present study is to clarify how radiological characteristics of teeth with PALs and previous root-canal treatment (RCT) influence the clinical evolution of the disease and to define the predictive value of its radiological and endoscopic features in determining the need for further surgical intervention. A total of 68 symptomatic patients with ODS with PALs were included in the study. The evaluation was performed by an otolaryngologist and a dentist based on a medical interview, nasal endoscopy, cold pulp testing and tomography images. Patients were prospectively followed for at least 12 months, during which nasal steroids, saline irrigations and RCT were administered. The criteria of disease improvement were: decrease of symptoms, healed sinonasal mucosa in endoscopy and radiological resolution of periapical radiolucency and sinus inflammation. Results showed that 9 (13%) patients improved after conservative treatment and 59 (87%) required further surgical intervention. Patients who improved after medical treatment and RCT were younger (p = 0.043) and had a greater distance from the top of the periapical lesion to the maxillary sinus' floor (p = 0.003). When expansion of PALs and bone destruction toward the maxillary sinus was observed on radiological imaging (p = 0.041), and when more than one tooth root was affected (p = 0.004), patients were more likely to require surgical intervention. In conclusion, the more roots that are affected and the closer the top of the PAL is to the maxillary sinus' floor, the greater the possibility of medical treatment and RCT failure. When the bone destruction extends into the maxillary sinus, patients eventually require both tooth extraction and FESS in order to resolve ODS completely.

Do Symptoms Correlate with the Signs in Odontogenic Sinusitis with Periapical Lesions?

INTRODUCTION: Endodontic pathology is one of the most common causes of odontogenic sinusitis, and its evaluation is challenging. Omission of periapical lesions in diagnostic process leads to recurrent sinusitis after cessation of medical therapy. METHODS: Sixty-one symptomatic patients presented with odontogenic sinusitis with periapical lesions of teeth adjacent to the maxillary sinus were included in the study. Symptoms evaluated with SNOT-22 and OHIP-14 questionnaires were compared to signs during endoscopic and radiological evaluation. RESULTS: Coexistence of odontogenic sinusitis with nasal polyps significantly decreases the quality of life, especially concerning the emotional domain (p = 0.047). Patency of ostiomeatal corresponds well with the severity of sinonasal symptoms reported with SNOT-22 (p = 0.051). Extent of maxillary sinus opacifications scored with Zinreich scale correlates positively with the presence of discharge (p = 0.001) and edema (p = 0.072) in the endoscopic Lund-Kennedy scale. Among 67 teeth with periapical lesions, 73.1% had undergone previous root canal treatment, but in 47.8% of cases, it was defined as incomplete. Endodontic status did not affect the severity of patient's complaints. CONCLUSION: In case of odontogenic sinusitis of endodontic origin, endoscopic signs correlate better than radiological with the self-reported symptoms. In order to better evaluate the severity of the disease and possible need of surgical intervention, both otolaryngologists and dental specialists should focus on extent of inflammatory lesions in the maxillary sinus.

The use and effectiveness of the TRV Chair - a literature review.

<b><br>Introduction:</b> Vertigo is a subjective sensation of swaying, tilting, spinning, instability, or being off-balance [1]. The concept of vertigo is not a precise term due to the possibility of its being related to numerous variable, frequently co-occurring sensations as experienced by the patient. For this reason, diagnosing the origin of vertigo quite frequently poses a serious dilemma for physicians. Dizziness can be of peripheral or central origin. Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral vertigo and is currently considered to account for about 14-42% of all cases of vertigo, depending on the authors [2-4]. However, this figure may be underestimated due to frequent misdiagnoses.</br> <b><br>Aim:</b> The aim of this paper is to review the currently available international literature on the use of the TRV chair so as to assess its usefulness and effectiveness in the diagnostics and possibly subsequent treatment of BPPV and its components.</br> <b><br>Materials and methods:</b> Included in this literature review are peer-reviewed papers authored by various research teams as available in PubMed, Google Scholar, and Scopus databases.</br> <b><br>Results:</b> The TRV chair is helpful in precise diagnosis and subsequent treatment of BPPV subtypes (canalithiasis and cupulolithiasis) as well as in the evaluation of the number of affected canals, as shown in the papers analyzed in this review.</br> <b><br>Conclusions:</b> The use of TRV in the context of diagnosis and therapy of benign paroxysmal positional vertigo presents with potential for the improvement of diagnostic results, management protocols, and patients' quality of lives.</br>.

The Influence of Steroid Therapy on the Treatment Results in Patients with Sudden Sensorineural Hearing Loss.

Oral, intravenous, or intratympanic steroid therapy (ST) are commonly applied methods of pharmacotherapy in Sudden Sensorineural Hearing Loss (SSNHL). There are vast discrepancies on the recommended initial dose and the duration of ST in medical reports. The aim of the research is a retrospective comparison of patients' examination results with different therapeutical strategies. The medical records of 218 patients treated for SSNHL at the Military Institute of Medicine were subjected to retrospective analysis by comparison of the results of pure tone audiometry prior to and after treatment with steroid therapy (first-dose delay, mass of first dose, duration of treatment). Postponement of implementation of ST to 5 days resulted in a significant improvement of hearing across all frequencies. The implementation of ST sequentially in periods (5th−10th day; >10th day) resulted in a statistically insignificant improvement of hearing in the following frequencies: 250 Hz, 1000 Hz, 1500 Hz, 2000 Hz, 3000 Hz, 4000 Hz. There was a statistical improvement of hearing within all frequencies analyzed for the initial dose of prednisone above 50 mg. For an initial dose below 50 mg, in 4000 Hz, the improvement of hearing was statistically insignificant. The research demonstrated a significant influence of steroid therapy on treatment results in patients with Sudden Sensorineural Hearing Loss.
