Background: Three-dimensional (3D) models generated from computed tomography (CT) images efficiently and accurately complement surgical comprehension. Additionally, computer modeling provides a substrate for comparative analysis of the treated orbit volume. This study aimed to investigate cases of orbital bone fractures with regard to orbital-defect correction, through 3D computational structural modeling and evaluation of orbital volume.

Hypernasality can be present as a result of velopharyngeal insufficiency, as well as nasal emission, weak pressure, articulatory errors and facial grimace, affecting speech intelligibility. Palatoplasty outcomes can be variable, and among the influencing factors are the surgical technique, the surgeon's experience, the postoperative care, and the patient/cleft characteristics.

This study purpose is to evaluate the maxillary relapse and associated factors in cleft lip and palate (CLP) patients submitted to standard Le Fort I advancement. This systematic review sought studies in PubMed, SCOPUS, and Cochrane and included papers that evaluated the maxillary relapse with at least 1-year postoperative period.
View Article and Find Full Text PDFPurpose: This study aimed to perform a systematic review about the use of xenogenous bonegraft in horizontal ridge augmentation to answer the following question: In implant patients, treated with xenografts for horizontal ridge augmentation, what would be the outcomes in terms of bone gain, bone resorption, implant survival, and complication rates?
Methods: The main search was performed at PubMed, Cochrane, and Scopus databases, and found 2610 articles. After selection and duplicate removal, 29 studies were included in the final review. The collected data were sample size, number and type of graft, site, horizontal gain, resorption rate, and complications.
Purpose: Coronectomy is an alternative technique to conventional lower third molar removal that aims to decrease inferior alveolar nerve impairment. The purpose of this study was to identify factors associated with reoperation after mandibular third molar coronectomy.
Materials And Methods: This systematic review sought scientific articles in the MEDLINE (PubMed), Scopus (Elsevier), and Cochrane Library databases.

The interest about upper airway evaluation has increased lately. Therefore, many softwares have been developed aiming to improve and facilitate the analysis of airway volume. The objective of this study was to compare two different softwares packages, Mimics and Dolphin, in their accuracy and precision in upper airway space measurements.
View Article and Find Full Text PDFOsteopetrosis is a rare condition which presents increased bone density and deficient bone remodeling. The consequential complications include cranial nerve impairment due compression, bone fractures, and osteomyelitis. Maxillary osteomyelitis is uncommon even in osteopetrosis patients.

Methods: A 7-year observational retrospective analysis was performed, and the injury-related data were collected from the medical records.
Orbital fractures are high prevalent and result in several complications such as diplopia, muscular entrapment, visual impairment, and enophthalmos. The goal of orbital reconstruction is to restore orbital anatomy, volume, and globe symmetry. This case report aims to describe the use of transantral endoscopy and 3D printed model for treatment of an orbital floor fracture.

We discuss the advantages of this less invasive technique, specially considering the early age of the patient and its bone growth, as well as the conservative approach for lesions in those cases. The treatment of an 8-year-old female patient exhibiting CGCL in anterior region of mandible with bone expansion is described.

The most common sequelae are pulp canal calcification (PCC) and pulp necrosis. The presence of pulp necrosis after PCC is reported in up to 30% of the cases and is a challenge due to the difficulty of endodontic treatment.

These implants promote a facial rejuvenating effect due to the attenuation of the nasal and chin prominences. The advantages of porous polyethylene include biocompatibility, dimensional stability, easy adaptation and fixation, low complication rate, and its availability in different sizes and shapes.

This article presents an unusual case of maxillary sinus mucocele as a late complication of zygomatic-orbital complex fracture, 23 years after the initial treatment. The patient was referring diplopia and decreased visual acuity with signs of dystopia, proptosis, and epiphora. Computed tomographic scan revealed an expansive lesion in the maxillary sinus with surrounding bone erosion and displacement of the eyeball.

In extensive orbital floor defects, the visualization of the posterior area is limited through inferior eyelid incisions. The use of endoscope may improve the treatment; however, it is a high-sensitivity technique.

This article aims to show the treatment of chronic sinusitis of odontogenic origin by surgical removal of ectopic teeth in an unusual position by direct visualization. This case report discusses the signs and symptoms of chronic sinusitis linked to the presence of ectopic elements and associated with an inflammatory cyst, the choice of complementary tests for diagnosis and surgical treatment through the Caldwell-Luc procedure.

The literature presents different opinions in several aspects, mainly regarding the effect of disjunction of the pterygoid plates. The aim of this study was to evaluate the pattern of maxillary expansion obtained with two surgical techniques, with and without disjunction of the pterygoid plates.
