ABSTRACT Aim (a) To study the variations in the superior attachment of uncinate process. (b) Incidence of pneumatization of uncinate process was also studied. Materials and methods A total 200 sides of 100 CT scans of paranasal sinuses coronal section were studied for variations in the superior insertion of uncinate process using Landsberg and Friedman classification. Incidence of pneumatization of uncinate process was also studied. Results In our study out of 200 sides, type 6 attachment was commonest (41%) followed by types 1 and 2. Pneumatization of the uncinate was seen in very small percentage of cases. Conclusion Lateral insertion of uncinate (lamina papyracea + aggar nassi) is the commonest variant followed by the insertion into the skulbase. Pneumatization of uncinate is rare. Clinical significance Though the inferior attachment of the uncinate is almost constant the superior attachment has several variations, the knowledge of which is very important for the endoscopic surgeon to avoid intraoperative complications.

Thyroid Cancer Incidence

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.

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.

Pathogenic Process

INTRODUCTION: There is increasing interest in the underlying bone of the paranasal sinuses as an important player in recalcitrant Chronic Rhinosinusitis. Close inspection of CT scans often reveals areas of increased bone density and irregular thickening of the sinus walls. This osteitic bone could at least partly explain, why inflammation of the mucosa persists. METHODS: We searched PubMed for all relevant studies, using the following text words: chronic rhinosinusitis, sinusitis, bone, osteitis, osteomyelitis, histology, and treatment. Cited references of retrieved articles were also examined. RESULTS: Background, available data, potential diagnostic options, treatment implications, and suggestions for future research are discussed. CONCLUSION: Osteitis is associated with CRS, however its role in the pathogenic process is not well defined. More research is needed.

AbstractWe report the case of a 57-year-old patient with a presumed developmental anomaly of the medial orbital wall. The resultant protrusion of orbital contents into the ethmoidal complex was clearly demonstrated on coronal computed tomography (CT) scans of the paranasal sinuses. This anomaly presents a high risk of iatrogenic injury to the medial rectus and orbit during functional endoscopic sinus surgery and has not previously been described.
