Sexual Dimorphism Using the Interstyloid Distances and Clinical Implication for Elongated Styloid Process in Northeastern Thailand

Abstract

SUMMARY:Skeletal remains are crucial in forensic identification of the sex, especially human skulls including the styloid process, a bony projection from the skull. Hence, the objectives of the present study were undertaken to assess the value of the styloid process for the sex identification of unknown skulls and also to investigate the prevalence of elongated styloid process in 102 human dry skulls from the northeast Thai population. As a result, the interstyloid distances at both base and tip of the styloid processes were found to be significantly different between male and female specimens, although no significant difference was found in the length of the styloid process between males and females. In addition, the occurrence of the elongated styloid process was not associated with the gender, although its prevalent laterality on the left was recognized. It is suggested that the styloid process can be applied to the sex identification by measuring the interstyloid distance at the base or the tip of these processes.

Elongation pattern of styloid process in Saudi population: a factor to remember in the prevention of eagle syndrome

“…Other studies had evaluated the SP elongation based on dry skulls, including Vadgaonkar et al [33] on indian, Sakaew el. [32] on Thai, Custodio et al…”

“…[16] While many studies suggest that SP considered elongated when it is longer than 30 mm. [32,30,17,18]. Although, there is limited number of studies consider the SP elongated when it exceeds 45 mm.…”

“…Custodio et al [ 1 ], Vadgaonkar et al [ 2 ], Natsis et al [ 32 ], Sakaew et al [ 33 ] evaluated SP elongation on dry skulls in Brazilian, Indian, Greek and Thai populations, respectively; other studies, such as that conducted by Kursoglu et al [ 4 ] on Turkish, More and Asrani [ 26 ] on Indian, Shaik et al [ 31 ] on Saudian and Al-Khateeb et al [ 34 ] on Jordanian populations were performed based on panoramic radiographs.…”

Interstyloid Distances in Northeastern Thailand

“…Dear Editor, i read the recent publication by Waraporn et al, on "Sexual Dimorphism Using the Interstyloid Distances and Clinical Implication for Elongated Styloid Process in Northeastern Thailand" with a great interest (Sakaew et al, 2016). Waraporn et al, noted that "it is suggested that the styloid process can be applied to the sex identification by measuring the interstyloid distance at the base or the tip of these processes" (Sakaew et al).…”

“…Waraporn et al, did not exclude the cases with underling thalassemia and hemoglobinopathy. Anyone with thalassemia and hemoglobinopathy can have the bone problem (including the maxilla) (Di Matteo et al, 2008) and this can be the missed uncontrolled confounding factor in the study by Waraporn et al He leído con gran interés la reciente publicación de Waraporn et al, titulada "El Dimorfismo Sexual Utilizando las Distancias Interestiloides y la Implicación Clínica para el Proceso Estiloides Elongado en el Noreste de Tailandia" (Sakaew et al, 2016). Waraporn et al señalan "se sugiere que el proceso estiloideo puede aplicarse a la identificación del sexo mediante la medición de la distancia interestiloide en la base o en la punta de estos procesos" (Sakaew et al).…”
