“…Sexual dimorphism of the greater palatine canal has been previously reported by Sheikhi et al ( 2013 ), and we agree that the craniofacial complex is highly variable in both size and shape by sex and that the zygomatic curve and skull size are generally larger in males than in females (Bigoni et al 2010 ). In a previous study (Tomaszewska et al 2014b ) we found that the length of the GPC, among other variables, can be successfully used to distinguish between sexes, with an overall accuracy of >78 %. In the present study we found a number of rather discrete side-related differences in both males (GPF lateral-medial dimension) and females (GPC length).…”

We have performed a detailed morphometric analysis of the length and anatomic routes of the greater palatine canal (GPC) and a systematic review of the literature on the anatomy of the GPC with the aim of informing dentists, maxillofacial surgeons, otorhinolaryngologists and other specialists performing procedures in the area of the GPC. In total, we analysed 1,500 archived adult head computed tomography scans to determine the length of the GPC and of the routes on both sides, as well as the dimensions and opening directions of the greater palatine foramen. The systematic review of the literature was performed according to PRISMA guidelines. The study group comprised 783 females (52.2 %) and 717 males with a mean (± standard deviation) age of 42.1 ± 16.9 years; there was significant difference in age between sexes (p = 0.33). The average length of the GPC was 31.1 ± 2.9 (range 15–44) mm. The GPC travelled three different paths in the sagittal plane and four different paths in the coronal plane. Most often it descended from the pterygopalatine fossa inferiorly before changing to an anterior-inferior direction (68.4 %; sagittal plane) and inferior-laterally before changing to an inferior-medial direction (40.7 %; (coronal plane). In total, the GPF had four different opening directions: inferior-anterior-medial (82.1 %), inferior-anterior-lateral (4.0 %), anterior (7.6 %), and vertical (5.3 %). Twenty-five studies were included in the systematic review. In conclusion, the information presented here provides clinicians with the anatomical knowledge necessary to minimize the risk of complications when performing procedures involving infiltration of the GPC.

“…The first equation was based on orale-spina nasalis posterior distance and had a sexing accuracy of 68.35%. The second equation was based on right greater palatine canal depth, orale-spina nasalis posterior distance and the anterior width of palatal arch and had a sexing accuracy of 78.37% [ 17 ]. The orale-spina nasalis posterior distance measured in this study is marginally longer than the incisive fossa to posterior nasal spine distance measured in our study.…”

“…The maxilloalveolar length was extremely significant with a P -value of 0.001 [ 18 ]. The orale-spina nasalis posterior distance in CT scans was also extremely significant with a P -value less than 0.001 [ 17 ]. In our present study all the three sagittal dimensions were extremely significant; the incisive fossa to posterior nasal spine distance with P -value less than 0.001, the palatine process of maxilla length with P -value of 0.004, and the horizontal plate palatine bone length with P -value less than 0.001.…”

“…There are also studies on palatal rugal patterns that conclusively establish their sexing significance [ 15 16 ]. Some authors have analyzed the palatal dimensions using computed tomography (CT) scans and confirmed their sexing significance [ 17] . Others have analyzed palatal dimensions in dry skulls where the maxillo-alveolar length and maxillo-alveolar breadth were conventionally used as sexing parameters [ 18 ].…”

Binary logistic regression analysis of hard palate dimensions for sexing human crania

Sex determination is the preliminary step in every forensic investigation and the hard palate assumes significance in cranial sexing in cases involving burns and explosions due to its resistant nature and secluded location. This study analyzes the sexing potential of incisive foramen to posterior nasal spine length, palatine process of maxilla length, horizontal plate of palatine bone length and transverse length between the greater palatine foramina. The study deviates from the conventional method of measuring the maxillo-alveolar length and breadth as the dimensions considered in this study are more heat resistant and useful in situations with damaged alveolar margins. The study involves 50 male and 50 female adult dry skulls of Indian ethnic group. The dimensions measured were statistically analyzed using Student's t test, binary logistic regression and receiver operating characteristic curve. It was observed that the incisive foramen to posterior nasal spine length is a definite sex marker with sex predictability of 87.2%. The palatine process of maxilla length with 66.8% sex predictability and the horizontal plate of palatine bone length with 71.9% sex predictability cannot be relied upon as definite sex markers. The transverse length between the greater palatine foramina is statistically insignificant in sexing crania (P=0.318). Considering a significant overlap of values in both the sexes the palatal dimensions singularly cannot be relied upon for sexing. Nevertheless, considering the high sex predictability of incisive foramen to posterior nasal spine length this dimension can definitely be used to supplement other sexing evidence available to precisely conclude the cranial sex.

“…2) Both palatine nerves -the greater and the lesser palatine nerve -originate from the sphenopalatine ganglion. The greater palatine nerve descends through the greater palatine canal (mean canal length 31 mm, range 15-44 mm) [35,36], and the greater palatine foramen to run anteriorly in a groove on the inferior surface of the hard palate. It innervates the hard palate and the palatal gingiva.…”
