Correlation between cranial base morphology and the position of the glenoid fossa in patients with facial asymmetry
No full textThe purpose of this study was to relate the facial asymmetries with possible impairments of the skull base, particularly with regard to the three-dimensional position of the glenoid fossa. Fifty-eight subjects met the inclusion criteria (25 men and 33 women) and were included in the analysis. All patients underwent three-dimensional computed tomographies. Patients were classified into 3 asymmetry groups: vertical plane asymmetries, transversal plane asymmetries (TAs), and hybrid forms. A control group, composed of 29 subjects having obstructive sleep apnea syndrome with no asymmetries, was used to compare data from the study populations. The glenoid fossa moved forward and superiorly on the affected side if compared with the healthy side both in the vertical plane asymmetry group and in the TA groups (P < 0.001). Differences were wider in the TA group. Statistically significant differences regarding the middle and posterior cranial base angles were observed between the affected side of the TA patients and the control group. We reported an amplitude reduction of the middle cranial base angle and an increase of the posterior cranial base angle in the affected side. The glenoid fossa could represent the missing link between the development of the temporal region and the ipsilateral hemimandible
The "beauty arch: " a new aesthetic analysis for malar augmentation planning
No full textMidface is a critical area for the aesthetics of the face. Despite malar hypoplasia is often combined with a class III malocclusion, there are few studies focusing on the results of a combined approach of malar implants and Le Fort I. We describe a new aesthetic analysis, named "beauty arch" analysis, for the assessment of sagittal projection of the malar region. We took a reference group of 74 Italian women participating in a national beauty contest in 2011 on which we performed our analysis. We used the ideal values to elaborate the surgical treatment planning of a second group of 45 consecutive female patients affected by skeletal class III malocclusion.Twenty-three patients undergo simultaneous Le Fort I osteotomy and malar implants. From the descriptive statistical comparison of the patients' values before and after orthognathic surgery and malar implants with the reference values, we observed how all parameters considered got closer to the ideal population. We consider our beauty arch a useful help for surgeon in the treatment planning of patients with skeletal malocclusions and malar implants
Trismus-pseudocamptodactyly syndrome: a 20 year follow-up
No full textTrismus-Pseudocamptodactyly Syndrome (TPS) is a rare autosomal syndrome characterised by the inability to open the mouth fully, pseudocamptodactyly, short stature and foot deformities. The maxillofacial feature entails hyperplasia of the coronoid processes which mechanically interfere with the zygomatic processes during mouth opening

Vertical distraction osteogenesis combined with bilateral 2-step osteotomy for preprosthetic rehabilitation of edentulous mandible
No full textThe aim of the current study was to appraise the effectiveness of distraction osteogenesis combined with bilateral 2-step osteotomy for the vertical augmentation of atrophic edentulous mandibles. To verify the predictability of this technique, we evaluated bone density and vertical bone gain of a cohort of 27 patients. The intraoral alveolar distractor was placed in the symphyseal area; then, it was left in situ for 2 months after surgery to consolidate the newly formed bone. A total of 189 implants were inserted. The main complications' issue was tied up to the neurosensory disturbances of the inferior alveolar nerve, which disappeared few months after the surgery.At the end of the distraction osteogenesis, a mean vertical bone gain of 10.5 mm evaluated by comparing preoperative and postoperative computed tomography was reached. Three months after the surgery, the radiologic data indicated that the difference in the mean bone density, recorded in Hounsfield units (HU), between the distracted bone and the preexisting mandibular bone was not statistically significant (P > 0.05). The last measurements done showed that the osseous density in the distraction chamber was higher than the original medullary bone density: the regenerated bones were more dense (876.8 [205.9] HU) than the preexisting medullary bone (312.1 [142.3] HU) and less dense than the preexisting cortical bone (1721.1 [170.4] HU) at the ninth month.In conclusion, this approach appeared to be a viable solution for the improvement of vertical volume in atrophic mandibles
