Correlation : Anatomical Variations of Nasal Cavity and Paranasal Sinuses and the Quality of Life Based on SNOTT-22 Score

This study aims to determine the correlation between the anatomical variations of nasal cavity and paranasal sinuses and the quality of life based on SNOT-22 score in the patients who underwent paranasal sinuses CT scan. The samples are 36 patients with age ≥ 18 years. The method is Chi Square test / Fisher's test and Spearman’s rho test. The results showed that anatomical variations of the nasal cavity and paranasal sinuses from most of the patients who underwent paranasal sinuses CT scan had septal deviation n = 29, p = 0.007 (p <0.05) and concha bullosa n = 15, p = 0.029 (p <0.05). There was a significant correlation between total anatomical variation and quality of life based on SNOT-22 score in the patients who underwent paranasal sinuses CT scan p = 0.025 (p <0.05). There was no correlation between the anatomical variations of frontal cells, agger nasi cells, ethmoid bulla, uncinate process and haller cells and the quality of life based on SNOT-22 score in the patients who underwent paranasal sinuses CT scan.

Instrumental Diagnosis Methods for ENT Diseases

As with any other clinical discipline, otorhinolaryngology uses both simple investigation methods including external examination of ENT organs with an otoscope, rhinoscope and laryngoscope, and more complex ones requiring the use of special devices and equipment. The latter include X-ray examination, US diagnostics, endomicroscopy of the nose and paranasal sinuses, CT and MRI (in case the study of soft tissue formations is needed). To study the auditory analyser functions and the labyrinth state, a number of functional tests are performed including stabilometry or postulography. Audiometry is performed with electroacoustic instruments and can be subjective and objective. Impedancometry, a method of objective hearing assessment, based on measuring the acoustic resistance of a soundconducting device, is used to determine the location and nature of the auditory system disorders. All these methods help establish the correct diagnosis, clarify the localisation of the pathological process and prescribe the correct treatment.

Thyroid Cancer Risk in Patients Undergoing 64 Slice Brain and Paranasal Sinuses Computed Tomography

Purpose: Computed Tomography (CT) is a fundamental part of diagnosis of diseases. During CT examinations organs in and out of scanned volume are exposed to ionization radiation. The aim of this study was Estimation Thyroid cancer risk in Patients who Underwent 64 Slice brain and paranasal sinuses CT scan. Materials and Methods: with permission from the authors and editor, data related to thyroid dose of 40 patients in Mazyar et al.'s paper was used and by using Biological Effects of Ionizing Radiation (BEIR)VII model thyroid cancer risk was calculated for different ages at exposure in male and female. Results: In both brain and paranasal sinuses CT, ERR values in female patients were twice as many as those in male patients. At age range from 20 to 40 years, ERR was considerably more than at age range 40-60 years since young patients are more radiosensitive than old patients. Conclusion: The calculations of ERR indicate that PNS and brain CT increase the theoretical risk of thyroid cancer incidence. Although the ERR values are low, impacts on the thyroid cancer incidence should not be disregarded.

Impact of rhinosinusal polyposis on CT score in patients with chronic rhinosinustis

Background/Aim. Chronic sinusitis is a disease characterized with mucosal inflammatoion of nasal and paranasal sinuses for at least 12 weeks. In order to assess the extent and severity of inflammatory changes in paranasal sinuses CT score according to Lund-Mackay is the most commonly used. Recent studies show the possibility of existing different subtipes of chronic rhinosinusitis, pointing out the presence of nasal polyps and their influence on the severity of chronic rhinosinusitis. The aim of this research was to examine the influence of sinonasal polyposis on the extensity of inflammatory changes on computerized tomography (CT), evaluated by the Lund-Mackay CT score. Methods. A prospective study compared the Lund-Mackay CT score values between the patients with chronic rhinosinusitis associated with nasal polyps and those without them. We determined mean values of the total CT score in both groups of the patients, as well as mean values of CT score for each group of sinuses and ostiomeatal complexes. Results. The study included 90 patients, 47 males and 43 females, 45-year old on average, diagnosed with chronic rhinosinusitis on the basis of diagnostic algorithm. The group with uncomplicated chronic rhinosinusitis (without nasal polyps) consisted of 30 patients and the group with complicated chronic rhinosinusitis (with nasal polyps) of 60 patients. Observing these two groups of patients revealed statistically highly important intergroup difference in CT score for each group of sinuses and ostiomeatal complexes. The mean value of total CT score in the group with uncomplicated chronic rhinosinusitis was 4.37 while in the group with complicated chronic rhinosinusitis it was 16.05 (p < 0.01). Conclusion. Chronic rhinosinusitis complicated by sinonasal polyposis is characterized with more extensive inflammatory changes on CT and, consequently, with higher CT score for each group of sinuses and ostiomeatal complexes, as well as higher total CT score.
