Anatomic Variations of the Paranasal Sinuses: Ct Examination for Endoscopic Sinus Surgery
(1999) Arslan, H.; Aydinlioglu, A.; Bozkurt, M.; Egeli, E.
Chronic rhinosinusitis endoscopic surgery requires an accurate evaluation of diseases and paranasal sinus anatomic variations. This study aims to show the main anatomical variations in the ostiomeatal complex and paranasal sinuses which are usually depicted by computed tomography (CT). CT scans obtained 2 mm thickness in axial and coronal plane from a series of 200 patients with chronic sinusitis were examined to determine the prevalence of anatomic variants. Anatomical variations determined were supraorbital recess in 6%, concha bullosa in 30%, sphenomaxillary plate in 17%, infra-orbital ethmoid cells (Haller's cells) in 6%, spheno-ethmoid cells (Onodi's cells) in 12%, pneumatization of the anterior clinoid process in 6%, carotid artery bulging into the sphenoid sinus in 8%, pneumatization of the uncinate process in 2%, paradoxical curvature of the middle turbinate in 3% and septal deviation in 36%. Level difference between the ethmoid roof and nasal vault was an average of 8 mm in right side and 9.5 mm in left side. Awareness of these different variations will help the rhinologic surgeon in his orientation during endoscopic surgical procedures.
Lumbosacral Angle in Lowback Pain
(1996) Tekeoglu, I.; Adak, B.; Bozkurt, M.; Kara, M.; Aydinhoglu, A.
Fifty patients with low back pain were evaluated for a possible relationship between the increase of lumbar lordosis (Ferguson's angle) and a group of chronic low back pain disorders such us fibromyalgias, lumbar disc degeneration, lumbar disc bulging, lumbar arthrosis and pain due to segmental instabilite. Another group consisted of thirty-eight healthy subjects who has never claimed previous backpain history were undergone spinal x-ray as a control group. The angle between a line parallel to the cranial end plate of S 1 vertebrae and a horizontal line was defined for the Ferguson's angle. In both groups patients were 30 years old or over. We also measured spinal instability in both groups by a vertical line from the middle of the corpus of L 3 vertebrae. The results showed that in the low back pain group there was a statistically significant increase in the Ferguson's angle and 62% of this group had spinal instability. In the control group the Ferguson's angle was in normal range and only 4% of them had spinal instability.
The Role of Power Doppler Sonography in the Evaluation of Superficial Soft Tissue Abscesses
(1998) Arslan, H.; Sakarya, M.E.; Bozkurt, M.; Ünal, Ö.; Dilek, O.N.; Harman, M.
Objective: To evaluate the efficacy of power Doppler ultrasonography in depicting increased vasculature and hyperemia around the superficial soft tissue abscess. Materials and methods: 21 patients with soft tissue abscess were evaluated with gray scale imaging, color Doppler sonography, power Doppler sonography and computed tomography. In each case attempts were made using power Doppler sonography to demonstrate any areas of increased vascularity around the lesion. The results were compared with computed tomographic findings. Results: Peripheral hyperemia and increased vasculature were demonstrated with power Doppler sonography in 19 of 21 patients with soft tissue abscess. The hyperemic area demonstrated around the wall of the abscess by power Doppler sonography was similar to the enhanced area shown by computed tomography performed after contrast administration. Conclusion: Power Doppler sonography shows increased vasculature and hyperemia in the wall of abscesses. Therefore, power Doppler sonography can be used to assist with the diagnosis of superficial soft tissue abscess.
The Role of Power Doppler Ultrasonography in the Diagnosis of Acute Pyelonephritis
(1998) Sakarya, M.E.; Arslan, H.; Erkoç, R.; Bozkurt, M.; Atilla, M.K.
Objective: To assess the ability of power Doppler ultrasonography (PDU) to detect acute pyelonephritis and to compare the findings from PDU with those from enhanced computed tomography (CT). Patients and methods: Eleven patients (mean age 18.5 years, range 5-37) admitted to hospital with a clinical diagnosis of pyelonephritis were assessed with PDU and enhanced CT, the latter providing the reference method. Results: The imaging studies showed normal findings in three patients; a single focus of pyelonephritis was detected by CT in six, whereas a matching defect was detected on PDU in five, with PDU failing to detect an infective focus in one. Multifocal diffuse pyelonephritis was diagnosed correctly by enhanced CT and PDU in two patients. Conclusion: Power Doppler ultrasonography had an overall sensitivity of 88% and complete specificity in the evaluation of patients with acute pyelonephritis.
