Three-dimensional computed tomography evaluation of craniofacial characteristics according to lateral deviation of chin

The relationship between the lateral deviation of chin and the upper and middle facial third asymmetry is still controversial. The purpose of this study is to evaluate the correlation of upper and middle facia...

This study seeks to categorize and quantify the incidental finding (IF) rate on CBCT in patients with cleft lip and palate (CLP) prior to orthodontic or surgical treatment. METHODS: This is systematic retrospective review of head and neck CBCTs in patients with nonsyndromic CLP taken between 2012 and 2019 at a single tertiary referral center. All assessments were performed independently by 4 observers (a head and neck radiologist and 3 orthodontists, including 2 fellowship-trained cleft-craniofacial orthodontists ). The images were divided into 9 anatomical areas and screened using serial axial slices and 3D reconstru...

Conclusion: Due to the wide variation in the morphology of nasopalatine canals, it is highly recommended to perform CBCT evaluation to the anterior maxilla before dental implantology in order to prevent any damage to the neurovascular bundle.

The effect of maxillary skeletal expansion (MSE) on upper airway in adolescent patients is not clear. The purpose of this study was to determine the upper airway airflow with MSE treatment using computational fluid dynamics analysis. Three-dimensional upper airway finite element models fabricated from cone beam computed tomography images were obtained before and after treatment in an adolescent patient with maxillary constriction. Turbulent analyses were applied. The nasal cavity (NC) was divided into 6 planes along the y-axis and the pharynx was divided into 7 planes in the z-axis. Changes in cross-sectional area, airflow...

This study aimed to introduce a novel method of precisely calculating the bone formation ratio using computer-aided engineering after surgery. A patient with a unilateral alveolar cleft who was treated with anterior iliac crest bone grafting was enrolled in this study. Helical computed tomography scans were performed preoperatively and 12 months postoperatively. The Digital Imaging and Communications in Medicine (DICOM) data were reconstructed as three-dimensional images and saved in the STL format by using Mimics software. STL data were processed by Geomagic Wrap 2017, using the Boolean operation, the newly formed bone of...

This brief clinical report describes our experience with virtual surgical planning in a case of mandibulectomy and mandibular reconstruction with a double barrel vascularized osteofasciocutaneous fibula free flap and immediate implant placement in a case of mandibular ameloblastoma. Fibular segments were positioned to obtain the best result both for masticatory function and for aesthetic facial appearance. Furthermore, in this particular case, as well as being positioned for future masticatory rehabilitation, the implants have served to stabilize the fibula segments in the reconstructive intraoperative phase. A superimposi...

Orbital subperiosteal hematomas are commonly caused by facial trauma. Nontraumatic subperiosteal orbital hematomas (NTSOHs) are rare but may occur in patients with underlying medical diseases. A 71-year-old woman presented to the emergency department with a 5-day history of left periorbital pain and proptosis. She was known to have Behcet disease and presented with no recent trauma. Clinical features and computed tomography findings aided in establishing the diagnosis of an NTSOH. The hematoma was evacuated via sub brow incision. After surgery, the patient's clinical symptoms resolved and did not recur during the 12-month ...

Conclusions: Immediate endonasal cartilage augmentation for iatrogenic saddle deformity after septoplasty is easy, safe, and effective. Furthermore, this corrective treatment for post op complication is very important for both of surgeon and patient. Predispositions to postoperative saddle deformity included site and severity of preoperative nasal septal deviation.

The pterygopalatine fossa (PPF) is a complex and paired anatomical structure located at the skull base. A clinically and surgically relevant structure located in the pterygopalatine fossa is the sphenopalatine ganglion. Electrical stimulation of the sphenopalatine ganglion is one possible method of treating cluster headache. The pterygomaxillary fissure (PMF) defines the pterygopalatine fossa laterally and determines the surgical approach. As part of preoperative surgical planning, each patient undergoes a preoperative head computed tomography or a cone beam computed tomography. In our study cone beam computed tomography i...

Alveolar soft part sarcoma (ASPS) is a rare malignancy of head and neck region; orbit and tongue being most common subsites affected by this rare tumor. A 5-year-old female presented with computed tomography scan evidence of right-sided prestyloid parapharyngeal mass. Complete excision was performed through trans-cervical approach. Histopathology, special stain, and immunohistochemistry of the resected specimen confirmed the diagnosis of ASPS. Three-year follow-up did not reveal any local recurrence or distant metastases. Review of the English-language scientific literature did not reveal any documented case of parapharyng...

Conclusion: Surgery in craniosynostosis patient increases the ICV besides it improves the shape of the head. From this study, the syndromic synostosis had better increment of ICV compared to nonsyndromic synostosis.
