“…7 Medial deviation was the most frequent variation of uncinate process observed, 8 and variations of bullous middle turbinate in 30.2%. 9 In this patient there was bullous at left middle turbinate seen in CT scan examination. This anatomic variation of the patient contributed as predisposing factor for CRS on the left nasal cavity.…”

Background: Nasal polyps are painless inflammatory lesions originated from around the middlemeatus or paranasal sinus cavity; while neurofibroma is benign peripheral nerve sheath tumor. Purpose:To report a rare case of neurofibroma concurrently with nasal polyps in chronic rhinosinusitis. Casereport: A 64-year-old female with chief complaint congestion on the right nose cavity. There was a mass on both nasal cavities. Patient diagnosed with benign mass at right nasal cavity and chronic rhinosinusitis with nasal polyps at left nasal cavity; with a differential diagnosis of chronic rhinosinusitis with bilateral nasal polyps. Computer tomography scan results showed homogeneous isodense lesion in the right nasal cavity, and mucosal thickening in left nasal cavity and maxillary sinus. Patient was managed with total extirpation of the bilateral nasal cavity mass and functional endoscopic sinus surgery. Pathological examination revealed neurofibroma in the right nasal cavity and polyps in the left nasal cavity. Clinical question: “How to differentiate inflammation with tumor of nasal and paranasal sinuses? Is there a causal relationship?” Review method: Literature searching was performed with the keywords “nasal cavity neurofibroma”, AND “nasal polyps”, AND ”chronic rhinosinusitis” through database Google Scholar, PubMed, and hand searching/e-book. Result: There were 11 literatures published in the last 5 years, and 7 articles relevant with the subject. Conclusion: Chronic rhinosinusitis with nasal polyps, along with neurofibroma on nasal cavity is a rare co-incidence, and there was no correlation between those lesions. Pathological examination is a gold standard in differentiating a definite diagnosis of neurofibromas and polyps.Keywords: nasal cavity neurofibroma, nasal polyps, chronic rhinosinusitis

“…Multislice computed tomography (MSCT) is a method of examination when an X-ray tube-detector rotates around the patient with a spiral trajectory, and as a result, there are multiple axial images of the interested area. Nowadays, modern scanners have the ability to perform fast examinations, obtain high-quality images, and reduce radiation exposure [3][4][5][6]. The patient is placed on the deck of the tomograph table in the supine position.…”

“…The patient's head is previously freed from all removable metal elements and evenly laid on the headrest, the patient's gaze is fixed centrally. When positioning the patient, laser marks are used to accurately determine the tomography area and a topogram is performed to mark the study area (Figure 3) [3][4][5]7].…”

“…MSCT is by far the obligatory and most informative X-ray method of examination in patients with anomalies of the dentoalveolar system and should be performed at the stage of preparation for the surgical treatment (Figure 10). With this type of study, the doctor receives the most comprehensive examination and has the ability to visualize the bone and soft tissue structures in two-dimensional and three-dimensional views [3,5,10].…”

The midface contains very important structures within the facial skeleton. There are number of diseases and pathological conditions that can happen in this region, which is why choosing the proper diagnostic tactic is very important for the benefit of the patients. The chapter “Radiology of the midface structures” covers the main features of bone and soft tissue structure diagnostics, including all the radiology methods such as X-rays, multislice computed tomography, cone-beam computed tomography, magnetic resonance imaging, and ultrasound. In the chapter, you can find the advantages and disadvantages of each method as well as the limitation of its usage. Every radiologist, ENT specialist, maxillo-facial surgeon, as well as residents and young doctors, should be very aware of the radiological anatomy of the midface structures and different pathological conditions and its radiological presentation. Therefore, a detailed review on the radiological state of the midface structures in normal and pathological conditions is presented.

Introduction. The structure of the nasal cavity and the sinonasal region is crucial in selecting treatment methods for their pathologies. Endoscopic surgery of the frontal sinus requires an assessment of the position and diameter of the frontal ostium, which can be determined and classified by analyzing a series of sinonasal computed tomography scans. The aim of our study was to investigate possible variations in the position and dimensions of the frontal sinus ostium and determine their frequency in individuals of mature age using computered tomography data.Material and methods. The study was conducted by analyzing 40 series of anonymized archived computer scans of 20 men and 20 women of mature age. The material for the study was obtained at the "Lithotripsy Center" (Lviv) on the Siemens SOMATOM GO.UP 32 (64) device (Germany). The evaluation and determination of the frontal ostium diameter were performed using the method described by Gheriani H. et al.[5].Results. Three variants of frontal sinus ostia were identified: with a positive, neutral, and negative evaluation. In 70% of examined women and 60% of examined men, the frontal sinus ostia received a positive evaluation on both sides, while in 10% of women and 10% of men, it was only on one side. Frontal sinus ostia with a negative evaluation were observed in 20% of women and 10% of men on one side. In 30% of women and 20% of men, the frontal sinus ostia had a neutral evaluation on one side, and in 20% of men, it was on both sides. The diameter of frontal ostia in both groups of men and women showed significant variability. In the studied group of individuals of mature age, the most common category of frontal ostium passability was the second category (50%), and the rarest was the fourth category (10%). The frequency of visualization of frontal ostia of the first and third categories was 45% and 30%, respectively. The symmetry of categories passability of frontal ostia in men was 80%, which was twice as high as in women. In men, the first category of frontal ostium patency was most frequently observed (50% of examined men), while in women, it was the second category (80% of examined women). The fourth category of frontal ostium passability was the least common in both men and women, each accounting for 10% of individuals of both genders.Conclusion. Computed tomography allows to determine the position and size of the frontal sinus ostium, which is crucial for assessing the complexity of surgical intervention.
