“…This cartilage has focused the investigations concerning calcifications on the infrahyoid area (Barut et al, 2020). These have shown that the TC is not a constant structure: its prevalence is variable just like its appearance and ossification patterns (Ahmad et al, 2005;Alqahtani et al, 2016;Wilson et al, 2017;Pinheiro et al, 2018;Vatansever et al, 2018;Barut et al, 2020). The lack of information on this piece of the human body has led experts to explore the calcifications involving it, and to find out whether its presence leads more often to abnormal calcifications in the thyrohyoid area (Vatansever et al, 2018).…”

“…The case reported here shows a calcification of the right lateral thyrohyoid ligament in continuity with the right GHH, but the presence of the TC is not clear. Thyrohyoid ligament calcifications are mostly related to the presence of the TC, although there is no consensus on all typologies; very few mention complete thyrohyoid ligament calcifications (Pinheiro et al, 2018). This information gap is due to the lack of reported cases of this type of calcification that is only referenced as a possible abnormality (Soerdjbalie-Maikoe and Van Rijn, 2008;Alqahtani et al, 2016), but has never been demonstrated and, therefore, studied.…”

Segmentation anomalies of the spine transformations are relatively common in humans, mainly in adjacent regions. Its aetiology is multifactorial, a combination of genetic, environmental, and epigenetic interaction. A sample of 50 adult individuals of both sexes from two different sites and chronologies of the current Argentine territory was examined. This work proposes a new approach to analyse segmentation anomalies, considering the taphonomic characteristics of the spine, together with the most common occasional contour shifts of such anomalies. Likewise, a bibliographic review was conducted to compile the knowledge achieved to date on this topic. The results showed different patterns of expression of segmentation anomalies among the analysed samples, with the lumbosacral transformations being the most prevalent. The similarities and disparities observed between Southern Patagonian samples and Inuit populations suggest that cold, as an environmental factor, could play an important role in the phenotypic plasticity of human populations. Similarly, hypoxia could influence the sample from Pukará de Tilcara. Due to the scarce existing methodological standardization for addressing segmentation anomalies, a systematization of the methods used to analyse segmentation anomalies is recommended; our approach is a proposal for this purpose.

“…Anatomical variation of these throat structures [ [37] , [38] , [39] ] and unusual patterns of ossification can complicate interpretation [ 40 ]. Some variations can be mistaken for trauma-induced alterations [ 41 ] or other medical issues [ 42 ].…”

In their analysis of recovered human remains, forensic anthropologists encounter structures of the throat (hyoid bone, thyroid cartilage/bone, cricoid cartilage/bone) that may present evidence of trauma. The recent published literature provides guidelines for the detection and interpretation of fractures in these tissues. Such traumatic injury frequently is associated with victims of hanging and strangulation, but many other causes have been recognized. Although the hyoid is not always recovered in skeletonized remains, it can reveal evidence of perimortem trauma and must be interpreted appropriately.

“…The shape of laryngeal cartilages is one important character that determines how the glottis opens or closes and tension is placed on the vocal folds (3)(4)(5). Shape variation of the human larynx is substantial (6)(7)(8)(9)(10)(11). The most important source of shape variation is sex (12)(13)(14), but some morphometric measures of the larynx are more variable than others even among sexes.…”

Laryngeal morphotypes have been hypothesized related to both phonation and to laryngeal pathologies. Morphotypes have not been validated or demonstrated quantitatively and sources of shape and size variation are incompletely understood but could be critical for the explanation of behavioral changes (e.g., changes of physical properties of a voice) and for therapeutic approaches to the larynx. Therefore results are likely to have implications for surgeons and speech language pathologists. A stratified human sample was interrogated for phenotypic variation of the vocal organ. First, computed tomography image stacks were used to generate three-dimensional reconstructions of the thyroid cartilage. Then cartilage shapes were quantified using multivariate statistical analysis of high dimensional shape data from margins and surfaces of the thyroid cartilage. The effects of sex, age, body mass index (BMI) and body height on size and shape differences were analyzed. We found that sex, age, BMI and the age-sex interaction showed significant effects on the mixed sex sample. Among males, only age showed a strong effect. The thyroid cartilage increased in overall size, and the angulation between left and right lamina decreased in older males. Age, BMI and the age-height interaction were statistically significant factors within females. The angulation between left and right lamina increased in older females and was smaller in females with greater BMI. A cluster analysis confirmed the strong age effect on larynx shape in males and a complex interaction between the age, BMI and height variables in the female sample. The investigation demonstrated that age and BMI, two risk factors in a range of clinical conditions, are associated with shape and size variation of the human larynx. The effects influence shape differently in female and male larynges. The male-female shape dichotomy is partly size-dependent but predominantly size-independent.
