Maxillary and Sphenoid Sinus Aplasia in Turkish Individuals: a Retrospective Review Using Computed Tomography
(Wiley, 2004) Aydinlioglu, A; Erdem, S
The absence of a maxillary or sphenoid sinus in an adult is an extremely rare condition. We investigated maxillary and sphenoid sinus aplasia in adult Turkish individuals using computed tomography (CT). We examined CT scans in the axial and coronal planes of the paranasal sinuses in 1,526 patients. The CT scans of a 21-year-old male were notable for bilateral maxillary sinus aplasia. Another patient, a 20-year-old female, had CT scans that showed the unilateral absence of a maxillary sinus. Two additional cases showed the unilateral absence of one sphenoid sinus. Bilateral absence of the sphenoid sinuses was not observed in our study. The clinical implications of maxillary and sphenoid sinus aplasia will be further discussed. (C) 2004 Wiley-Liss, Inc.
Symptomatic Anomalies and Arthrotic Formations of the Axis Vertebrae in Eastern Anatolian People - a Local Investigation
(Univ West indies Faculty Medical Sciences, 2004) Aydynlyoolu, A; Yesilyurt, H; Erdem, S; Diyarbakirli, S
At the craniocervical junction, developmental anomalies of the axis may produce clinical symptoms by compressing the upper cervical cord during movements of the head and neck. The present study aimed at investigating several varieties and deformities of the axis on skeletal specimens of Eastern Anatolian origin. On 76 specimens, developmental anomalies and the variants of the second vertebrae (axis) were investigated. Hypoplasia of the dens axis in one specimen, the dens axis of a child with a bifid apex in another specimen and an arthrotic formation located on the apex of the dens in six axes were found A bone protrusion narrowing the transverse foramen was also observed The types of absence of the dens axis and clinical symptoms that may be caused by them are discussed It was concluded that the frequency of arthrotic formations might reflect the possibility that the individuals suffered less commonly from neck pain due to arthrotic degeneration.
Variants and Deformities of Atlas Vertebrae in Eastern Anatolian People
(Saudi Med J, 2004) Kavakli, A; Aydinlioglu, A; Yesilyurt, H; Kus, I; Diyarbakirli, S; Erdem, S; Anlar, Ö
Objective: At the craniocervical junction, developmental anomalies of the atlas may produce clinical symptoms by compressing on the vertebral artery, particularly during extreme rotational movements of the cervical spine. The aim of the present study was to investigate several varieties and deformities of the atlas vertebra from the skeletal specimens of Eastern Anatolian people. Methods: This study was carried out over a 3-year period, 2000 through to 2002 in the Department of Anatomy, Firat, Yuzuncu Yil and Ataturk University, Turkey. Developmental anomalies and the variants of the first vertebrae were investigated on 86 atlas. Results: Ponticulus posterior was observed with a low frequency on right as 2.3%. The bilateral localization was 10.5% and the left-side localization was 9.3%. Ponticulus lateralis showed an equal localization as 1.2% on the right, 1.2% on the left and 1.2% bilateral. In the present study, a complete subdivision of the joint surface was observed in 11 atlases (12.8%). Processus infratransversarius atlantis with a frequency between 1.2-7%, arthrotic formation and corona atlantis peridentals in 8 cases (9.3%) were also found. Conclusion: The low frequency for fonticulus posterior might be peculiar to the population living in this area.
