An R Script to Estimate Which and How Many Landmarks Represent the Most Variable Parts of an Object

Int. j. morphol; 42 (2), 2024
SUMMARY: The study of the shape variation in geometric morphometrics has an important limitation known as the Pinocchio effect. The Pinocchio effect produces artifactual variances of the landmarks and implies that it is not possible to know the morphological change structure of an object, other than by d...

Analysis of the Asterion Morphology in Relation to Its Clinical Significance

Int. j. morphol; 41 (6), 2023
SUMMARY: The asterion presents a significant anthropological marking and meeting point between three sutures. It is a surface landmark for the transverse-sigmoid venous sinus complex and is also a surgical landmark for access to the posterior cranial fossa, giving it clinical importance. The aim of this ...

Angle Evaluation of Possible Routes that Can Be Used to Reach the Foramen Ovale in the Anterior Approach

Int. j. morphol; 41 (6), 2023
SUMMARY: For the treatment of trigeminal neuralgia, the foramen ovale is reached by entering the cheek with a needle. Thermocoagulation is performed with balloon compression, administration of alcohol or radiofrequency. Apart from the classical method, it is theoretically possible to reach the foramen ov...

Evaluation of Head and Cervical Spine Posture after Therapy with Maxillary Protraction Appliances

Int. j. morphol; 41 (3), 2023
SUMMARY: The objective of this study was to evaluate the changes of head and cervical spine posture of skeletal class malocclusion in adolescent with maxillary protraction. Thirty cases of skeletal class malocclusion were randomly selected from the Stomatological Hospital of Shanxi Medical University. Hi...

Relationship between the occlusal plane and three different levels of ala-tragus line in a sample of sudanese adults

J. oral res. (Impresa); 12 (1), 2023
Aim: Correct orientation of the occlusal plane plays a vital role in achieving the perfect occlusal balance and function of complete dentures. This study aimed to evaluate the most reliable posterior reference point of the ala-tragus line (ATL) concerning occlusal plane (OP) in a sample of the dentate Su...

Development of craniofacial superimposition: a review

Int. j. morphol; 40 (6), 2022
SUMMARY: Craniofacial superimposition is a method for identifying individuals by using secondary data in order to identify a target group of persons before a DNA process can be used, or to identify an individual instead of using primary data in cases where DNA, fingerprint or dental records are not found...

F approach algorithm in missing landmark problem

Int. j. morphol; 40 (1), 2022
SUMMARY: Missing data may occur in every scientific studies. Statistical shape analysis involves methods that use geometric information obtained from objects. The most important input to the use of geometric information in statistical shape analysis is landmarks. Missing data in shape analysis occurs whe...

A guideline for femoral nerve block with the age-related formulas obtained from the distances between the femoral nerve and surface anatomical landmarks in fetal cadavers

Int. j. morphol; 40 (1), 2022
SUMMARY: The femoral nerve (FN) is used for nerve block in many surgeries and provides effective postoperative analgesics in the pediatric population. However, although there are sufficient anatomical maps and signs for femoral nerve blockades in adults, there is not enough information for the pediatric ...

Vestibular landmarks to minimize injury to the mental nerve during transoral endoscopic thyroidectomy-vestibular approach (TOETVA) procedure: an anatomical study

Int. j. morphol; 40 (4), 2022
SUMMARY: The aim of this study is to reveal the morphometry of the mental nerve to describe a safe zone for minimizing mental nerve damage during transoral endoscopic thyroidectomy-vestibular approach (TOETVA). This study was performed on 12 cadavers. Localization of mental foramen according to teeth, di...

Estudio dimensional de los puntos craneométricos mediosagitales en cráneos de población chilena

Int. j. morphol; 40 (5), 2022
RESUMEN: La utilidad de los puntos craneométricos en neurocirugía radica en la estudiada relación que poseen con las estructuras encefálicas y vasculares que subyacen, siendo relevantes al momento de planificar y realizar diversos abordajes y disminuir la morbilidad asociada. A pesar de esto, hasta e...
