Cone beam computed tomography evaluation of pterygoid hamulus

Introduction: The hamular process topographically arises from the terminal part of the medial bone lamina and it is a sickle or hook-shaped process located distal and medial to the maxillary tuberosity. Its morphology is very varied as well as its size and its terminal portion can be thin or bulbous...

description Introduction: The hamular process topographically arises from the terminal part of the medial bone lamina and it is a sickle or hook-shaped process located distal and medial to the maxillary tuberosity. Its morphology is very varied as well as its size and its terminal portion can be thin or bulbous. In the literature, the average length and width are 5.3 mm and 1.6 mm, respectively. It commonly has a lateral deviation in the coronal plane and a posterior deviation in the sagittal plane. The present study aimed to analyze the morphology and morphometry of hamular processes in Cone Beam Computed Tomography (CBCT) slices. Cone-beam computed tomography slices of 200 patients (100 male and 100 female) were analyzed. A field of view of 80 mm by 80 mm and an isotropic voxel size of 200 µm. Images obtained were viewed and analyzed with Romexis software 4.4.0.R. where Hamular processes measurements were taken. In the different slices, the Hamular processes were observed as cortical bone hyperdense images. They presented an average length of 5.42mm and an average width of 1,80 mm. The deviations of the hamulus laterally outwards in the coronal plane presented an average angle of 32°. In the sagittal slices, hamular processes presented a posterior deviation (85%). In our study, the morphology and size of these bone processes presented similar values to those reported in the literature. Knowledge of the statistically most frequent morphological and morphometric characteristics of hamular processes allows the dental professional to diagnose different pathological alterations, such as their abnormal deviation or their elongation that may be a cause of different disorders such as obstructive sleep apnea or hamular process syndrome.

Introducción: El proceso hamular topográficamente surge de la parte terminal de la lámina ósea medial y presenta forma de hoz o gancho y se localiza distal y medialmente a la tuberosidad maxilar. Su morfología es muy variada al igual que su tamaño y su porción terminal puede ser delgada o bulbosa. En la literatura su longitud y su ancho promedio son de 5,3 mm y 1,6 mm respectivamente. Comúnmente presenta una inclinación lateral en el plano coronal y una inclinación posterior en el plano sagital. El objetivo del presente trabajo fue analizar la morfología y la morfometría de los procesos hamulares en cortes de tomografía computada cone beam. Materiales y métodos: Cortes de tomografía computada cone beam de 200 pacientes (100 masculinos y 100 femeninos) fueron analizados. Se empleó un campo de visión de 80 mm por 80 mm, con voxel isotrópico de 200 µm. Las imágenes obtenidas fueron visualizadas y analizadas con el software Romexis 6.0.R. Se realizaron las mediciones de los procesos hamulares. Resultados: En los diferentes cortes se observaron los procesos hamulares como imágenes hiperdensas de hueso cortical. Presentaron una longitud promedio de 5,42 mm y un ancho promedio de 1,80 mm. Las desviaciones de los hamulus lateralmente hacia afuera en el plano coronal presentaron ángulo promedio de 32°. En los cortes sagitales presentaron una desviación posterior. Discusión y conclusiones: En nuestro estudio la morfología y dimensiones de estos procesos óseos presentaron valores similares a los relatados en la literatura.  El conocimiento de las características morfológicas y morfométricas estadísticamente más frecuentes de los procesos hamulares permiten al profesional odontólogo diagnosticar diferentes alteraciones patológicas de los mismos como su desviación anormal o su elongación que pueden ser causa de diferentes trastornos como la apnea obstructiva del sueño o el síndrome del proceso hamular Facultad de Odontología 2023-08-03 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion application/pdf https://revistas.unc.edu.ar/index.php/RevFacOdonto/article/view/42098 Revista de la Facultad de Odontología; Vol. 33 Núm. 2 (2023): Rev Fac Odont 32(2)-2023-Agosto; 15-22 2545-7594 0325-1071 spa https://revistas.unc.edu.ar/index.php/RevFacOdonto/article/view/42098/42257 https://creativecommons.org/licenses/by-nc-sa/4.0
