Maxillary and sphenoid sinus aplasia in Turkish individuals: a retrospective review using computed tomography.

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.

Absence of frontal sinus in Turkish individuals.

The frontal sinus has been used for personal identification since the early part of the 20th century as a result of its tremendous interindividual variation. The frontal sinus is present in approximately 90% of adults. However, some populations have a higher proportion of people without a frontal sinus. This study investigated the frequency of the absence of frontal sinuses in Turkish individuals. The present study was performed retrospectively on the CT scans of the paranasal sinuses in the axial and coronal planes from a series of 1200 cases. A bilateral absence and a unilateral absence of sinuses were found in 3.8% and 4.8% of cases, respectively. The clinical significance of the frontal sinuses and their absence are also discussed.

A morphometric study on the humerus for intramedullary fixation.

In recent years, the popularity of intramedullary humeral nailing is on the rise in spite of its handicaps. There are many problems in intramedullary humeral stabilization because of the anatomic structure of the bone. We performed various methods and measurements to determine shape, length and diameter and curvature of the medullary canal of the humerus in 57 human dry cadaver bones. Anterior angulation with an average of 21 cm apart from greater tubercle was found at 1/3 distal part. Mean degree of angulation was 9 degrees (max: 15, minutes: 5, S.D.: 2.84). Humerus bones with septal aperture (supratrochlear foramen) at the fossa coronoidea were observed to have very narrow medullary canal. The best point for nail insertion was found to be an area on the line from greater tubercle anteromedially to caput humeri. This study revealed that carefully evaluated structure of humeral medullary canal and various congenital constructions such as septal aperture, and correct selection of a nail with proper length and diameter are essential for successful nailing.

Sex differences and right-left asymmetries in rat hippocampal components.

Previous reports have indicated morphologic hippocampal asymmetry in thickness in male and female rats. In the present study, the possible sex differences and right-left asymmetries in rat hippocampal components were investigated. Pyramidal cells in four hippocampal sectors on thionin-stained sections were counted and the thickness of the hippocampal components was measured on microslide-projected images. The present study showed significant sexual dimorphism in two hippocampi as well as asymmetry in male. These findings agree with those found in humans.
