Dermoid Cyst: Unusual Localization
No full textDermoid cysts are embryonic lesions usually observed in the lateral eyebrow region and the midline nose and neck areas. Communication of these lesions with the central nervous system is rare and occurs in the nasal region. There are few clinical reports of temporal dermoid cysts presenting with intracranial extension, and we present a 15-year-old girl with a fronto-orbital dermoid cyst with intracranial extension and bone erosion. Her presenting symptom was a lacrimation reduction of the left eye. Excision of the cyst was done using a coronal approach because of its extension and localization
Variations of the gonial angle in vertical surgical reduction of the maxillary-mandibular complex
No full textFrom an esthetic point of view, the mandibular or gonial angle plays an important role in ensuring a harmonious facial profile. The purpose of this study was to analyze the values of the mandibular angle in relation to variations of the vertical and sagittal positions of the jaw. The study was carried out on a sample of 42 patients who underwent surgery for maxillary-mandibular repositioning, advancing or raising the jaw, after a Le Fort I osteotomy and bilateral sagittal osteotomy of the jaw according to the technique described by Obwegeser-Dal Pont. In all patients, the maxillary bone was raised with a discrepancy of at least 3 mm between the anterior and posterior portions (favoring the latter) as a result of (clockwise) rotation of the bispinal plane. The data, obtained by means of cephalometric analysis according to the method of Ricketts, showed how changes in the gonial angle differed between patients who require correction of an open-bite and those who do not. In particular, in patients without an open-bite, advancement of the maxilla limited the opening of the angle. Similarly, in patients with an open-bite, the tendency to form an open gonial angle can usually be corrected by the association of advancement of the maxilla whenever possible
Compression and Stretching in Graves Orbitopathy: Emergency Orbital Decompression Techniques
No full textVisual loss from orbital compression and stretching of the optic nerve is an infrequent but well-recognized cause of dysthyroid optic neuropathy, occurring in less than 5% of thyroid eye disease cases. Another important but less recognized cause of vision loss due to thyroid-associated optic neuropathy is protracted stretching of the optic nerve. Of the reported cases of compression and stretch optic neuropathy, none have documented the rate of vision loss due to continuous stretching of the optic nerve
Ozone therapy in extractive surgery on patients treated with bisphosphonates
Full text linkIt is certain that oral extractive surgery is a remarkable trigger to avascular osteonecrosis of the jaw in patients treated with pyrophosphate analogous. This acquisition limits the use of endo-oral surgery in those patients, even when they have already developed the lesions. In this study, we present the results obtained in a group of 15 patients deriving from a 33-patient cluster with osteonecrosis of the jaw in treatment at our department with a new protocol based on ozone therapy. The object of this article is to demonstrate how dental extraction becomes possible in a patient with avascular bisphosphonate-related jaw osteonecrosis or in those who simply received pyrophosphate analogous when proper treatment with ozone therapy has been done
Surgical Treatment of Temporomandibular Joint Ankyloses: Meniscus Conservation and Relocation
No full textAnkylosis of the temporomandibular joint is a serious complication, mainly after trauma and local or systemic infection. In rare cases, ankylosis is associated with systemic disease such as ankylosing spondylitis, rheumatoid arthritis, and psoriasis. According to the functional restriction and the provoked disturbances of facial growth in the youth, an early and effective therapy is desirable. There is a wide variety of surgical approaches to temporomandibular joint ankylosis, ranging from chondro-osseous grafts to prothesis. In the article the authors present the clinical case of a 60-year-old patient who, at the age of 6, accidentally fell from a height of about 2 m. In 60 years old, after removing the temporomandibular ankylosis with surgical technique, patient showed a marked improvement of mandibular kinetics.Ankylosis of the temporomandibular joint is a serious complication, mainly after trauma and local or systemic infection.

Etiology and incidence of zygomatic fracture: a retrospective study related to a series of 642 patients
No full textBACKGROUND AND OBJECTIVES: The aim of this paper is to investigate epidemiological data (age, gender), sites, etiology and surgical approach of zygomatic fracture. MATERIALS AND METHODS: A 9 years retrospective clinical and epidemiologic study evaluated 642 patients treated for zygomatic fracture. There were 569 men and 77 women. The age range was 2 to 86 years with 205 (31.9%) in the 21 to 30 years age group. A number of parameters, including age, gender, cause of injury, site of injury, treatment modalities were evaluated. RESULTS: There were 552 (86%) zygoma fractures and 90 (14%) zygomatic arch fractures. The left zygoma was involved in 309 cases (56%); the right zygoma was involved in 243 cases (44%). Concerning the zygomatic arch, the left side was involved in 43 cases (48%) and the right side in 47 cases (52%). 7% of the patients were younger than 9 years old, about 70% between 10 and 39 years, and 18% between 40 and 59 years, while 4% were older than 60 years. Causes of zygoma fracture were traffic accidents in 151 (26%), assault in 117 (20%), accidental falls in 105 (19%), sports injuries in 56 (10%), home injuries in 45 (8%), work accidents in 34 (6%). Causes of zygomatic arch fractures 28 (29.1%) were assaults in 28 (29.1%), traffic accidents in 20 (21.5%), sports injuries in 14 (15.8%), accidental falls in 11 (14%), domestic accidents in 8 (8.8%) and work accidents in 4 (5%). The access to the fronto-zygomatic suture (74.6%) and the maxillary vestibular approaches (66.8%) were the commonest method of reduction of zygomatic fracture. About arch fractures, the Gillies temporal approach was the most used method of reduction (94.4%). CONCLUSIONS: The findings, compared with similar studies reported in the literature, support the view that the highest prevalence is in young male patients and, concerning cause, traffic accidents and assault are the most frequent
Aesthetic restoration in maxillo-mandibular malformations: the role of genioplasty
Full text linkAim: The aim of this study was to determinate how orthognatic surgery aids to cure many skull and face abnormalities and to help re-establishing the correct occlusive relation thanks to the repositioning of the maxillo-mandibular skeleton basis.
Methods: The study included 183 male patients and 338 female patients, with an average age of 23 years. The sample series was divided according to specific pathologies. All patients underwent surgical procedures and the therapeutic strategy was determined based on the anomalies presented.
Results: 113 patients had a II class dental skeletal occlusion, 180 patients had a III class dental-skeletal occlusion and 222 patients had skull-facial abnormalities. 5 patients underwent only a genioplasty, 82 patients underwent a genioplasty associated with BSSO, 175 patients underwent a genioplasty associated with Le Fort I osteotomy and the remaining 253 patients underwent a genioplasty associated with BSSO and Le Fort I osteotomy.
Conclusion: The experience shows that genioplasty has been successfully introduced in orthognathic surgical therapeutic procedures, for dental-skeleton abnormalities and mandibular asymmetries treatment. In recent years, the evolution of computer systems has allowed an accurate assessment and programming, by means of the three-dimensional display, which are of great help in the course of diagnosis and evaluation of the displacements to be carried out, in order to obtain optimal aesthetic results
Injections in Aesthetic Medicine: Atlas of full-face and full-body Treatment
No full textThe use of injectables, known as dermal fillers, is becoming ever more popular in aesthetic medicine. Full-face and full-body treatments using such fillers are increasingly substituting for various surgical techniques; not only do they provide immediate results at a lower cost, but they also avoid the use of general anesthesia and shorten the recovery period. In addition, dermal fillers can be successfully used for body remodeling, for example in patients with bow legs and those requiring breast remodeling.This book outlines the fundamental principles of the use of different fillers and injection techniques in the treatment of facial and body areas. An impressive collection of sequential color photographs illustrate the procedures step by step and demonstrate the results. The volume will be an invaluable tool for aesthetic doctors, practicing dermatologists, plastic surgeons, and all other physicians interested in the field of aesthetic medicine.
Fronto-orbital mucoceles: our experience
No full textFrontal sinus mucoceles are rare benign neoplasms that can result in bony erosion extending from the borders of the sinus into the orbital cavity. The authors report the fronto-orbital mucoceles they have observed in the last 8 years. The authors used an "open surgery" approach in 12 fronto-orbital mucoceles, characterized by an osteoplastic frontal flap, through a coronal incision or Lynch incision. In this way, they were able to expose the frontal sinus and to remove completely the mucocele from the periorbita. Only one recurrence is reported 2 years after surgery. Excellent aesthetic results have been reached in all cases. In the literature, many different positions are reported for the treatment of mucoceles. The endoscopic surgery of the paranasal sinuses has become the procedure of choice for mucoceles of maxillary, ethmoidal, and sphenoidal sinuses. However, few authors have recommended the endoscopic approach for frontal mucoceles. The indications and limitations of endoscopic and "open" surgery are critically discussed in the light of the authors' personal experience and current literature
