Aim: to study the morphological patterns of polypous tissue according to cytology and histology. Pateints and methods: 78 patients with a confirmed diagnosis of polypoid rhinosinusitis (PRS) were selected for the study, including 50 men and 28 women aged 25 to 74 years. The material for cytology was scraped from the surface of nasal cavity and paranasal sinus (PNS) polyps, as well as touch smears from the cut surface of removed polyps, and the material for histology was pieces of removed polypous tissue. Results: in the course of the study, the following comparative analysis of the obtained results was made: a) with polyps with a fibrous component in touch smears, there are expressed signs of chronic inflammation along with signs of respiratory epithelial cells proliferation; b) edematous and myxoid polyps are commonly combined with an allergic condition; c) analysis of cytomorphological signs of the respiratory epithelium of the nasal cavity and PNS in PRS indicates a structural alteration of the mucous membrane in this disease. The epithelial proliferation is associated with the activation of stroma components — fibroblasts and leukocytes. At the light-optical level, the characteristics of compensatory and adaptive changes that contribute to the morphofunctional cell unity preservation of the mucous membrane that counteract the pathological process are revealed. Conclusions: according to the method of sampling material for cytology, the most informative are touch smears from the cut surface of the removed polyp, which help to identify more morphological patterns of the polypous tissue. The analysis of cytomorphological features of the respiratory epithelium of the nasal cavity and PNS in PRS indicates the remodeling of the mucous membrane in this disease. The epithelial proliferation is associated with the activation of stroma components — fibroblasts and leukocytes. At the light-optical level, the characteristics of compensatory and adaptive changes that contribute to the morphofunctional cell unity preservation of the mucous membrane that counteract the pathological process are revealed. The obtained results will help to understand the mechanisms of structural and functional alteration in the nasal mucosa and PNS in PRS.

Schwannomas of the paranasal sinus are uncommon. Less than 4% of schwannomas involve the nasal cavity and paranasal sinuses, even less in the pediatric age group. A case of schwannoma arising in maxillary sinus in a 2.5-year-old Chinese boy is reported. The basis for discussion of this case is the exceptional rarity of sinonasal schwannoma in pediatric patients.

Maxillary sinus squamous cell carcinoma is an invasive tumour that is usually diagnosed at an advanced stage, where the majority of patients have a very low prognosis and survival rate. We present a case of maxillary sinus carcinoma that affected the entire orbit, resulting in proptosis of the eye and nasal cavity. The patient was recommended for palliative treatment due to the high degree of its involvement and proximity to vital structures. It manifests with very mild to no signs, resulting in a late diagnosis. As a result, physicians must be mindful of maxillary sinus pathologies to make an early diagnosis. Paranasal sinuses are air-filled spaces located close to vital structures such as visual organs and the face. Maxillary, ethmoidal, frontal, and sphenoidal are the 4 paranasal sinuses that are named according to the bones in which they are situated. Nasal cavity and paranasal air sinus malignancies are uncommon. According to the literature, paranasal sinus malignancies account for less than 1 % of all human malignancies and 3 % of the total malignancies of the head and neck region. However, the maxillary sinus is the most frequent site of origin of primary malignant tumours amongst the paranasal sinuses.1 we need to raise general awareness among the oral stomatologists as Asian countries report a very high incidence of maxillary sinus carcinoma.2 The incidence of malignancies in maxillary sinus is high (60 % - 70 %) and less in the nasal cavity (12 % - 25 %), the Ethmoid (10 % - 15 %) and very rare in sphenoid / frontal sinuses (1 %).3 Further, not only the malignancies of maxillary sinuses are common, but they also incur the worst prognosis. Maxillary sinus carcinomas have very few symptoms and are similar to those of chronic paranasal sinusitis. They usually present themselves as locally advanced diseases. 4,5 Paranasal sinus malignancies are difficult to diagnose in the early stages and 90 % of cases are reported in T3 / T4 advanced stage.6 Environmental factors such as industrial pollutants, dust, smoke, and adhesives are the leading causes for the development of disease.7 Thus, sinonasal malignant tumours are rare and pose a challenge in diagnosis as well as treatment. Therefore, maxillofacial specialists should be aware of the signs and symptoms of this rarely occurring disease. This article presents a rare case of a 45-year-old female who reported to our OPD with a complaint of swelling in the right zygomatic area and proptosis of the right eye.

Tooth Retention

According to the literature, such dentition anomaly as supernumerary teeth is more common in the practice of a dentist than of an otorhinolaryngologist. Clinical manifestations of this pathology in adults are less frequent than in children. Periodically, there appear descriptions of individual cases of hyperdentia, in which the tooth is located in the nasal cavity, paranasal sinuses, orbit. It is not always possible to find such a tooth on examination, therefore, additional research methods help to determine the location and pathological process in more detail. We present our clinical observation of tooth retention and ectopia in the nasal cavity and upper jaw. The diagnosis was confirmed by the data of endoscopic examination and computed tomography of the paranasal sinuses. The ectopic tooth was found before the development of pronounced local inflammation. The tooth was removed from the nasal cavity using endoscopic techniques, no communication between the nasal cavity and the oral cavity was found. The postoperative period was uneventful. On examination two weeks after the operation, no pathological changes in the nasal cavity, paranasal sinuses were found, as well as defects in the mucous membrane and bone part of the nasal cavity floor.

Malignant schwannomas of the paranasal sinuses are extremely uncommon tumors, as only 18 well-documented cases have been previously published in the English-language literature. We report two new cases of solitary malignant schwannoma—one in a 23-year-old man and the other in a 45-year-old woman. Neither was associated with von Recklinghausen's disease. These tumors involved the maxillary sinus, nasal cavity, and orbit and extended intracranially. Following surgery, both patients experienced recurrences. The male patient developed a slowly enlarging intranasal mass at the same site 8 years following excision of the original tumor and postoperative radiotherapy. Microscopic examination of the recurrent tumor revealed that its features were similar histologically to those of the original. The female patient experienced a recurrence 1 year following her first operation.

Relevance: despite the available methods and medicines, rhinosinusitis occupies a leading place in the structure of diseases of the upper respiratory tract. Rhinosinusitis can be a consequence of respiratory viral infections, can be an independent nosological unit. In recent years, there has been a protracted course of rhinosinusitis with a long recovery period with chronic inflammation in the paranasal sinuses and nasal cavity. Purpose of the study: to analyze the validity and effectiveness of therapeutic approaches to the treatment of chronic rhinosinusitis using the Polydexa with phenylephrinum nasal spray with phenylephrine Materials and мethods: The study included 121 patients — 61 (50.41 %) women and 60 (49.59 %) men aged 25 to 50 years, a history of chronic rhinosinusitis in the stage of clinical exacerbation at the time of the study. All patients underwent: otorhinolaryngological examination, general clinical and radiological (radiography or computed / magnetic resonance imaging of the paranasal sinuses). Cytological examination of the detachable nasal cavity was carried out to study the calculation of the relative number of neutrophilic granulocytes, macrophages, epithelial cells, lymphocytes. Microbiological examination of the detachable nasal cavity and paranasal sinuses included the study of the qualitative and quantitative composition of pathogenic and opportunistic organisms on the surface of the nasal mucosa. Results: in patients with chronic rhinosinusitis in the stage of clinical exacerbation, an increase in the relative content of inflammatory elements was revealed in the nasal secretion against the background of the prevailing content of pathogenic staphylococci and streptococci. The use of topical preparations containing antibacterial components of a broad antimicrobial spectrum of action, dexamethasone, phenylephrine hydrochloride helps to relieve inflammation on the surface of the mucous membranes of the nasal cavity and paranasal sinuses. Conclusions: a method of treating chronic rhinosinusitis in the stage of clinical exacerbation using a combined preparation for topical application containing neomycin sulfate, polymyxin B sulfate, dexamethasone sodium metasulfobenzoate, phenylephrine hydrochloride has a pronounced anti-inflammatory, decongestant, antibacterial effect

Back ground: Nasal cytology has generally been employed as a useful diagnostic tool in the differentiation of rhinopathies. Objective The aim of this study was to assess the extent and diagnostic value of inflammation of nasal and paranasal sinus mucosa in chronic rhinosinusitis patients by employing a combination of nasal brushings and a liquid-based cytological technique. Methods Forty-eight patients with chronic sinusitis and 20 control subjects without any sign of sinusitis undergoing endoscopic surgery, although not all underwent endoscopic sinus surgery, were recruited to the study. Nasal cytology samples were collected from all subjects using nasal brush and processed a liquid-based cytological technique for evaluation of total and differential inflammatory cell counts. Biopsies were also taken from the inferior turbinates from its anterior margin in all subjects and from identical lateral maxillary sinus mucosa in patients with chronic sinusitis during surgery and routinely processed for staining and evaluation of inflammatory cells. Results Total and individual inflammatory cell counts in nasal brushings were significantly correlated with the respective inflammatory cell counts in biopsies obtained from the inferior turbinate (eosinophils: r = .519 and P = .016; neutrophils: r = .540 and P = .012; lymphocytes: r = .540 and P = .011) but not in biopsies obtained from the maxillary sinus. No correlation was observed between the inflammatory cells in biopsies from the inferior turbinate and biopsies from the maxillary sinus. The liquid-based cytological technique showed higher sensitivity (94.1%), specificity (76.9%), and positive predictive value (84.2%) for inflammation in the inferior turbinates than for inflammation in the maxillary sinus (sensitivity = 63.4% and positive predictive value = 63.4%). Conclusion Nasal cytology evaluated by use of nasal brushings processed by a liquid-based cytological technique is likely to have higher diagnostic value for the inflammatory response in noninfectious rhinitis than in chronic rhinosinusitis.
