The Attractiveness of Facial Profile: A Random Population Survey on the Relationship of Jaws
No full textIntroductionThe face is an extremely important feature that plays a central role in communication and social interaction of a species. The human brain has developed specific circuits to read and recognize facial patterns.On top of that, mankind, more than any other species, has developed the sense of harmony and beauty, when it comes to physical appearances, with special regards to the face.IntroductionThe face is an extremely important feature that plays a central role in communication and social interaction of a species. The human brain has developed specific circuits to read and recognize facial patterns.On top of that, mankind, more than any other species, has developed the sense of harmony and beauty, when it comes to physical appearances, with special regards to the face.ObjectivesThe aim of the study is to evaluate the attractive perception of neutral profile images with different maxillofacial alterations. To do so, the perspective of randomized subjects is taken into consideration, highlighting the possible implication for the maxilla facial surgery.MethodsA survey has been structured with 18 neutral profiles images, 9 female and 9 males. The profile silhouettes used were converted into black and white images using Adobe Photoshop software, which helps obtaining a better evaluation of the facial attractiveness excluding external factors. The survey was administered to 135 randomized subjects, who were asked to evaluate every single image in a scale from 1 (unattractive) to 5 (extremely attractive).ResultsThe summary has shown a tendency of evaluating the normal occlusion profile as attractive, thus revealing a general constancy in the beauty standards. Among the other profiles evaluated, the maxillary protrusion also obtained a high score of evaluation, in terms of attractiveness, registering a score of 3 in 37% of cases and a score of 4 in 35% and 31% for men and women's profiles, respectively.The retrognathic maxilla has been evaluated as strongly non-attractive in women (66% of cases); while, it was considered medium attractive, 3 out of 5, in men (38% of cases).The profiles with mandibular protrusion have been evaluated as non-attractive with score of 2 in 42% of cases in men, and a score of 1 in 41% in women. Interestingly, the bimaxillary profile for both male and female images were considered as neutral by most of the subject, marking a non-statistical difference in comparison with the normal profiles. Statistically different are the data obtained from the other analyzed profiles.ResultsThe summary has shown a tendency of evaluating the normal occlusion profile as attractive, thus revealing a general constancy in the beauty standards.

Pleomorphic adenoma of the lacrimal gland: two clinical cases
No full textINTRODUCTION: Pleomorphic adenoma of the lacrimal gland is uncommon but it is the most common benign epithelial tumor of this gland. In the literature few cases have been reported in patients aged between 6 years and 80 years with a mean age of 39 years. A correct diagnosis and treatment is fundamental in order to avoid a relapse and sometimes their malignant transformation. An incisional biopsy is better to be avoided because it could injure the capsule, leading to dissemination of tumoral cells in the orbital tissues with a recurrence rate of 30% over 5 years. AIM: This papers want to support the use of mini-invasive surgery for the treatment of orbital lesions when it is possible. MATERIALS AND METHODS: We report two clinical cases of pleomorphic adenoma affecting the lacrimal gland treated with two different surgery approaches. The radiographic and photographic documentation of the patients was collected in the pre-and post-operatively. All patients underwent a CT scan and MRI. CONCLUSIONS: This lesions requires a well-grounded clinical and therapeutic protocol to avoid the risk of malignant transformation or disease recurrence, very dangerous at this site. CT scan and MRI scan are very important to recognize different types of lesions involving the lacrimal gland and fossa. A mini-invasive surgery reduces hospitalization, risk of complications, surgical times and bleedings and guarantees an excellent functional and esthetic result when performed by a skilled surgeon
Le Fort III osteotomic variants
No full textINTRODUCTION: Midface hypoplasia is a skeletal defect involving all three space planes, hence needing a three-dimensional repositioning. This research study shows two cases of cranio-facial dysostosis, on which two Le Fort III variants were performed. CASE REPORT: In the first case we report the performing the two types of osteotomy simultaneously. Le Fort I, however, has been performed without any pterygomaxillary disjunctions, thus accomplishing a complete midface mibilization without any variation of the occlusal ratios. In the second case a modified Le Fort III osteotomy has been performed with median disjunction; reduction of the transverse interdacryal diameters and of the pyriform opening. DISCUSSION: Among all osteotomic variants we would like to mention the one introduced by Obwegeser in 1969 where, in patients with acceptable dental occlusal ratios, Le Fort III and Le Fort I have been performed in conjunction. This technique allows a different midface and dental occlusion repositioning. CONCLUSIONS: In adult patients with permanent dentition and normal occlusal ratios - this technique may be chosen for a midface advancement without compromising the dento-skeletal relations, in order to achieve the best functional and aestetical results
