Unilateral condylar hyperplasia: diagnosis, clinical aspects and operative treatment. A case report.

BACKGROUND: Condylar hyperplasia of the mandible is an uncommon idiopathic disorder of the jaw characterised by increased volume of the condyle, unilaterally or bilaterally, leading to facial asymmetry, mandibular deviation, malocclusion and articular dysfunction. CASE REPORT: The authors present one case of unilateral condylar hyperplasia of a 16-year-old patient affected by severe facial asymmetry. Conventional X-rays examinations, multislice spiral CT and bone SPECT were used for the final diagnosis of primary condyle hyperplasia. The patient was treated with a combined orthodontic and surgical approach. CONCLUSION: Treatment of condylar hyperplasia with a combined orthodontic and surgical approach including condylectomy yield good aesthetic and functional outcomes.

A monolateral TMJ replacement under intraoral endoscopic assistance for jaw osteomielitis: a modified approach.

Alloplastic replacement has become a valid treatment for TMJ endstage disease. The Alkayat and Bramley pre-auricular approach combined with the submandibular incision are the current surgical approaches for TMJ surgery. The present study shows a modified approach using intraoral endoscopic assistance. A female patient affected by jaw osteomielitis with condylar detachment was treated with total left TMJ alloplastic replacement combined with a right TMJ arthroplasty. No subamandibular incision was performed and, subsequently, the risks for permanent or temporary damage to the marginalis mandibulae nerve and surgical submandibular scar were avoided. Postoperative CT-Scan evidenced a good prosthesis position. No complications occurred after two years of follow-up.

Odontoameloblastoma: five years follow up of a surgical case and review of literature.

The odontoameloblastoma (OA), also known as ameloblastic odontoma, is a rare neoplasm of jaws which includes odontogenic ectomesenchyme in addition to odontogenic epithelium that resembles an ameloblastoma both in structure and in behaviour. The exact incidence is difficult to determine. Since 1944, only 24 cases have been reported in English literature which fulfill both histological and clinical features of this lesion. The Authors report a case report of an odontoameloblastoma in a 15-year-old caucasian man treated with a surgical excision. The five years follow-up shows no evidence of recurrence confirming the validity of a conservative surgery with enucleation of OA, followed by periodical clinical and radiographical controls.

Maxillofacial Injuries in Padel Game.

Background: Maxillofacial injuries are very frequent in the sports environment. Padel is a new sport of Mexican origin, very popular in Mexico, Spain, and Italy, but with a rapid spread in Europe and other continents. Aims: The aim of this article is to report our experience of 16 patients with maxillofacial injuries that occurred during padel matches in 2021. All these injuries occurred due to the racket bouncing against the glass of the padel court. The bounce of the racquet is given either because the player was trying to hit the ball near the glass or by throwing the racket against the glass for an act of nervousness. Methods: We carried out a literature review about sports traumas, and we calculated the possible force with which the racket, once bounced off the glass, hits the players' faces. Results and Conclusions: The racket, bouncing off the glass wall, arrives with a specific force in the face of the player who threw the racket, being able to cause skin wounds, injuries, and fractures mainly at the level of the dentoalveolar junction.

Histochemical and morphological aspects of fresh frozen bone: a preliminary study.

Bone graft are used in dentistry for the reconstruction of severely atrophic jaws. Fresh frozen bone has no osteogenic property but it has osteoconductive and osteoinductive properties because its matrix contains growth factors such as vascular endothelial growth factor. The purpose of the present study was to evaluate morphological and protein expression characteristics of fresh frozen bone before graft and after six months of graft in patients who needed maxillary reconstruction. After 6 month of graft we observed the presence of viable bone as evidenced by full osteocyte lacunae and by the presence of RANKR, osteocalcin positive cells and vascular endothelial growth factor. In conclusion, our findings show that the fresh frozen bone after six month of graft is for the most part viable bone, encouraging its use as an alternative to autogenous bone for reconstructing maxillary bone defects prior to implant.

Traumatic Pseudoaneurysm of the Internal Maxillary Artery: A Rare Life-Threatening Hemorrhage as a Complication of Maxillofacial Fractures.

Pseudoaneurysm of the internal maxillary artery due to a traumatic event is a rare condition. Pseudoaneurysms are usually directly produced by arteries break with extravasation of blood. The compressed perivascular tissue forms the wall of aneurysmal sac. Then, this sac gradually expands and can be damaged. It is rare to see pseudoaneurysms of IMA. They are usually associated with fracture of the neck of the mandible. To the best of our knowledge the pseudoaneurysm of the internal maxillary artery related to maxillofacial trauma is an event extremely rare in the literature and if not quickly managed can lead to the patient's death. This case underlines how the close cooperation between surgeons and radiologists results in a quick diagnosis and management of such pathological events.

Radiofrequency catheter ablation in drug refractory maternal supraventricular tachycardias in advanced pregnancy.

BACKGROUND: Treatment of maternal tachyarrhythmias in pregnancy is a major clinical issue. Pharmacological treatment raises important concerns regarding partial efficacy and side effects. Radiofrequency ablation of arrhythmogenic substrate has rarely been performed during pregnancy because of the fetal risks related to x-ray exposure and potential fetomaternal procedural complications. CASES: Three women affected by supraventricular tachycardias refractory to pharmacological therapy underwent successful radiofrequency catheter ablation at 29 to 30 weeks' pregnancy. All patients had cesarean delivery of newborns with normal Apgar scores. CONCLUSION: Radiofrequency catheter ablation is an effective treatment of drug refractory maternal supraventricular tachycardias in advanced pregnancy. Further studies are required to establish its long-term fetal safety.

Bioengineering in the oral cavity: our experience.

BACKGROUND: To date, there are no studies reported in the literature on the possible use of bovine collagen, oxidized regenerated cellulose, or synthetic hyaluronic acid medications in the oral cavity. The aim of this paper is to report the use of bovine collagen, oxidized regenerated cellulose, and synthetic hyaluronic acid medications to improve wound healing in the oral cavity by stimulating granulomatous tissue. METHODS: From 2007 to 2011, 80 patients (median age 67 years) suffering from oral mucosal lesions participated in this double-blind study. The patients were divided into two groups, each consisting of 40 patients. One group received conventional medications, while the other group of patients were treated with the advanced medications. RESULTS: Advanced medications allowed re-epithelialization of the wound margin in 2-20 days, whereas patients receiving conventional medication showed a median healing duration of 45 days. CONCLUSION: The results of this study demonstrate that treating oral mucosal wounds with advanced medication has an advantage with regard to wound healing time, allowing patients to have a rapid, functional, and esthetic recovery.
