A dissection based study of the dimensions of the thyroid cartilage in Anatolian population

Abstract

Accurate knowledge of the dimension, shape, and morphology of larynx and its complex anatomy is a prerequisite for performing surgery of the larynx. Population differences are important not only for planning surgical interventions but also for performing an operation. Previous morphometrical studies on the larynx had shown variable results obtained from different populations, including Western and Eastern ones, yet information about larynx morphometry in Anatolian population is limited. The purpose of this study is to make more statistical data available for Anatolian population and help clinicians for surgical approaches related to this area. Ten parameters from anterior and lateral views were measured on 50 thyroid cartilages taken from autopsy specimens (28 male, 22 female). Specimens were removed and dissected under stereomicroscope after routine fixation procedure. Those with visible deformations were eliminated during dissections. Statistical evaluations and comparisons were done for a comprehensive description. Significant sexual differences were observed. Mean values for all parameters were higher in males than in females. These results were compared with already existing anatomical data of other populations. This study on larynx specimens from different regions of Anatolia provides a general knowledge of thyroid cartilage dimensions. The obtained results can have great clinical influence on surgical approaches to the related area and give information for anthropomorphic studies.
