Abstract
To analyze the relation between the anthropometric linear measurements of the skull and face and the measurements of width and length of the hard palate. Twenty-three human skulls were used, and the measurements were collected with the help of a caliper and pelvimeter. The following linear measurements were studied: maximum cranial length, biporion distance, maximum face width, nasal height, palatal length, and palatal width. After a complete descriptive assessment of the variables, we observed homogeneity in the measurements of the skull, face, and palate. There were correlations, with higher significance, between the palatal length and width and the maximum face width and the biporion distance, respectively. The biporion distance was the only measurement that was significant in the explanation, generating formulas to obtain the palatal length and width. It is possible to estimate the palatal length and the palatal width using the two models (formulas) through the measurements of the biporion distance. Because in the literature, there is no consensus, there is a need for standardization when obtaining the linear measurements of the palate.
Highlights
The hard palate plays an important role in the functions of the stomatognathic system
In 7 skulls, it was not possible to measure the palatal width (Bi–endomolare bilaterally (Enm)), and, in 4 skulls, the palatal length (Ol – Sta), because the pieces were damaged in places where the three craniometric points would be obtained
According to the coefficient of variance (CV), and the presented data, it can be noted that the measurements are homogeneous, as, for example, in the mean of the palatal width (Bi–Enm)
Summary
The hard palate plays an important role in the functions of the stomatognathic system. Morphological alterations in the structure of the stomatognathic system entail adaptations in deglutition, mastication, speech articulation, and breathing This means that, in the evaluation of the hard palate, if the morphology is altered, the functions that need this structure will likely be altered or at least adapted[2]. Despite the importance of anthropometry in s peech-language pathology and audiology, in the area of orofacial motricity, the morphology and morphometry of the hard palate have not been studied very intensively by professionals in this area[2]. There is no consensus in the literature regarding the nomenclature in the subjective evaluation of the hard palate within the practice of speech-language pathology and audiology. It can be observed that the hard palate is difficult to assess clinically, and part of that difficulty is owing to the lack of objective measurements[3]
