Evaluating Surgical Approaches for Hemimandibular Hyperplasia Associated with Osteochondroma: A Systematic Literature Review.

: Hemimandibular hyperplasia (HH) associated with osteochondroma presents complex challenges in maxillofacial surgery, including facial asymmetry, occlusal instability, and temporomandibular joint (TMJ) dysfunction. Surgical interventions vary widely in approach and outcomes, underscoring the need for a systematic evaluation of effectiveness. This systematic review assesses the effectiveness of surgical approaches for managing HH associated with osteochondroma, focusing on techniques including condylectomy, orthognathic surgery, distraction osteogenesis, total joint replacement (TJR), and genioplasty.

Volumetric differences in the temporomandibular joint in patients with condylar hyperplasia in active and passive state, SPECT/CT study.

Aim: Condylar hyperplasia (CH) is a progressive and deforming disease that modifies anatomy of the temporomandibular joint (TMJ) structures. This study aims to correlate the metabolic bone activity of the condyle measured by SPECT with the volumetry anatomic information from the condyle, fossa and joint space provided by CT images, in patients with CH in active and inactive forms.

Materials And Methods: A cross-sectional comparative study was performed with a set of 116 images from healthy and diagnosed CH patients to compare volumetric measures of the TMJ.

Anatomical factors of the maxillary tuberosity that influence molar distalization.

Objective: To examine the areas of the maxillary tuberosity (MT) (coronal, apical, width, and height) with respect to the presence or absence of the third molar to establish possible anatomical limitations for molar distalization.

Methods: A total of 277 tuberosities were evaluated through sagittal computed tomography (CT) images, divided for measurement into coronal (free of bone), apical (area of influence of the maxillary sinus), and tuberosity (bony area) zones, and stratified by the presence or absence of the third molar, sex, and two age subgroups. Mann-Whitney test was used to compare the groups considering the third molar.

Positional Features of the Mandibular Condyle in Patients with Facial Asymmetry.

Objective: To describe the position of the mandibular condyle, the size of the joint spaces and the condylar angulation in patients with facial asymmetry (FA), and to classify these results according to the type of FA and compare them with a reference group without FA. Materials and Methods/Patients: An observational, cross-sectional, descriptive study using computed tomography (CT) was conducted on a sample of 133 patients with a clinical diagnosis of FA derived from the following entities: hemimandibular elongation (HE) ( = 61), hemimandibular hyperplasia (HH) ( = 11), condylar hyperplasia in its hybrid form (HF) ( = 19), asymmetric mandibular prognathism (AMP) ( = 25), glenoid fossa asymmetry (GFA) ( = 9) and functional laterognathism (FL) ( = 8). Likewise, a group of 20 patients without clinical or tomographic characteristics of FA was taken and their complete cone beam tomography (CBCT) scans were analyzed.

SPECT/CT Correlation in the Diagnosis of Unilateral Condilar Hyperplasia.

Objective: To evaluate the correlation between metabolic bone activity measured by single photon emission computed tomography (SPECT) and the anatomic condylar characteristics acquired by computed tomography (CT), in patients with unilateral condylar hyperplasia (UCH). Method and Materials/Patients: Observational, descriptive study in a group of 71 patients with clinical diagnosis of UCH and indication of SPECT/CT. Bone SPECT images obtained in a gamma-camera GE Infina and processed in a station Xeleris 3 with the program Volumetrix MI Evolution for bone.

Reference values of mandibular condyles metabolic activity: A study using Tc-MDP single-photon emission computed tomography.

Objective: To assess the condylar bone metabolic activity in patients with temporomandibular joint health by measuring Tc-MDP uptake using a single-photon emission computed tomography (SPECT) to establish reference values of the uptake difference between condyles and the ratio with respect to the clivus.

Setting And Sample Population: Eighty consecutive patients of both sexes who were admitted to a Nuclear Medicine Centre between 2017 and 2019 were included in the study.

Method: This was an observational cross-sectional study in patients with SPECT indications to evaluate pathologies other than those of the temporomandibular joint.

Mandibular and temporomandibular morphologic characteristics of patients with suspected unilateral condylar hyperplasia: a CT study.

Introduction: Facial asymmetry associated with unilateral condylar hyperplasia (UCH) is a complicated clinical condition.

Objective: The objective of this study was to describe morphological characteristics of the mandible and the temporomandibular joint in patients with facial asymmetry, using computed tomography and 3D reconstruction.

Methods: A retrospective observational study was performed with patients displaying facial asymmetry evaluated by single photon emission computed tomography (SPECT)/CT analysis, for suspected UCH, between 2015 and 2018.

Are There Mandibular Morphological Differences in the Various Facial Asymmetry Etiologies? A Tomographic Three-Dimensional Reconstruction Study.

Purpose: Facial asymmetries (FAs) have been classified according to the mandibular morphological differences to obtain better diagnostic and treatment decisions. The purpose of the present study was to establish diagnostic differentiation among FAs using computed tomography (CT) and 3-dimensional (3D) reconstruction.

Materials And Methods: We performed a cross-sectional study of patients with a diagnosis of FA, who had been evaluated by CT and 3D reconstruction in the same clinical center from 2015 to 2018.

Condylectomy and "surgery first" approach: An expedited treatment for condylar hyperplasia in a patient with facial asymmetry.

Condylar Hyperplasia (CH) is a self-limiting pathology condition that produces severe facial deformity at the expense of mandibular asymmetry. In this case report a 15-year-old female patient was diagnosed with Unilateral Condylar Hiperplasia (UCH) by mean of single-photon emission computed tomography (SPECT) and histological study. A high condylectomy in the right condyle was performed to stop the active status of the hyperplasia.
