“…Their study illustrates significant gender differences in the distance between the descending palatine canal and the piriform rim. In this regard, the distance was significantly greater in males (p = 0.037) [14]. The measurements of the medial plate of the pterygoid process of the sphenoid bone, and the thickness of the pterygomaxillary region, demonstrate that these parameters were also longer on either side in females.…”

“…Alternatively, numerous scholars have analyzed neighboring regions' dimensions. Odobasi et al (2020) have drawn attention to the clinical significance of the pterygomaxillary region, noting that this region may have different anatomies and may also lead to specific complications during surgery [14]. Their study illustrates significant gender differences in the distance between the descending palatine canal and the piriform rim.…”

This study evaluates the differences in the dimension, symmetry, and anatomical characteristic of the tubero–palato–pterygoid region in adults using 3D printed models. The objective of this study was also estimation of how many tubero–pterygoid implants can be placed safely with enough distance between threads of implants. The investigation draws on 57 models of upper jaws, including the adjacent pterygoid process of the sphenoid bone from randomly selected cases. The consecutive measurements (lateral, medial, rostral, caudal, area, line-1 longitudinal, and line-2 transverse) on both sides of the body—right (R) and left (L)—were used for the purpose of this study. Among the group of 57 cases were 30 females (F) and 27 males (M). A strong correlation was identified between lateral and line-1 longitudinal across the sample group of both male and female cases (p ≤ 0.05; r ≥ 0.9). Moreover, a strong correlation was noted between medial and line-1 longitudinal in the whole group of cases and in the male group (p ≤ 0.05; r ≥ 0.9). Lateral and line-1 longitudinal demonstrated a weak positive relationship with the age of the female cases (p ≤ 0.05; 0.03 < r < 0.05). Medial and line-1 longitudinal showed a weak negative relationship with the age of the male cases (p ≤ 0.05; −0.05 < r < −0.03). The results of this study suggest that, in most cases, two such tubero–pterygoid implants may be placed, which is a good advantage for support of implant-based bridges.

BACKGROUND:Le Fort 1 (LF1) osteotomies are widely used to correct midface deformities. To move the maxilla freely, the pterygomaxillary junction (PMJ) must be separated. When performing this osteotomy, the pterygoid plate must remain intact. The objective of this study was to evaluate relationship between the anatomical features of the PMJ and fracture patterns in LF1 osteotomy. METHODS:Pre-operative and post-operative cone-beam computed tomography images of 41 patients (82 samples) who have undergone LF1 osteotomy surgery were radiologically evaluated. Morphologic measurements of the pterygomaxillary fissure area and pterygoid plate were carried out. Moreover, pterygomaxillary separation was divided into the clean-cut, maxillary sinus, and pterygoid plate fracture types. RESULTS:Statistically significant difference was observed between clean-type fracture and pterygoid plate fracture groups' thickness of the pterygoid process and thickness of the pterygomaxillary region. CONCLUSION:Anatomical variations make it difficult to separate the PMJ properly. Low thickness of PMJ increases the risk of unwanted fractures; however, according to our experience, the use of an osteotome with an incorrect angle, excessive force, and inexperienced surgeons can also cause undesirable pterygoid plate fractures.

“…1 La etiología de los CE por lo general es de carácter traumático (accidentes automovilísticos, accidentes laborales y/o deportivos, agresión por terceros con arma de fuego, armas blancas u objetos punzocortantes), también pueden ser resultantes de complicaciones transoperatorias como fractura www.medigraphic.org.mx magnética, ecografía, entre otros, cada uno con diferente especificidad e indicación, estos exámenes permitirán determinar el tamaño, la forma y la densidad del CE, además de determinar su relación con estructuras anatómicas adyacentes, ya sean vasculares, nerviosas, musculares u óseas. [8][9][10] En la actualidad, los softwares de planificación virtual 3D para odontología pueden proporcionar información mucho más clara y precisa del CE, así como confeccionar guías 3D personalizadas para la remoción quirúrgica del CE en ciertos casos cuando el acceso lo permita. 3 La fosa pterigomaxilar (FP) contiene estructuras vasculares y nerviosas de importancia que pueden entorpecer el acceso quirúrgico, este mismo se realiza comúnmente mediante abordajes abiertos transfaciales o mediante endoscopia transnasal para el tratamiento de neoplasias que afectan la FP.…”
