Complications of orbital floor repair with silastic sheet: the skin fistula.

Treatment of orbital floor fracture is a subject of great interest in maxillofacial surgery. Many materials have been described for its reconstruction.In this article, the authors report a case of a patient who, 7 years from a previous orbital floor fracture and treatment with silastic sheet, presented herself to their clinic for the failure of the material used for its reconstruction and a skin fistula.Orbital floor repair with silastic sheet is an old method that no one uses anymore, but we still observe cases of late complications with this material. So a fine knowledge of silastic sheet complications is needed for young surgeons.The authors report the case and perform a literature review about the use of more modern biomaterials for orbital floor reconstruction.

Retrospective analysis of 301 patients with orbital floor fracture.

The purpose of this study was to retrospectively analyse patients with orbital floor fracture who were treated at the Department of Odontostomatology and Maxillofacial Surgery, Policlinico Umberto I, Sapienza University of Rome, Italy, between 2008 and 2013. Patients were evaluated by age, sex, aetiology, clinical findings, fracture pattern, ocular injury, treatment, complications, and sequelae. We evaluated surgical outcomes and complications with the use of different surgical approaches and various materials used to reconstruct the orbital floor. In total, there were 301 orbital fractures. Two hundred and seventeen patients were men (72.1%) and 84 were women (27.9%). The average age of the patients was 37.2 years (range, 9-90 years). The leading cause of these fractures was violent assault (27.3%). Pure blow-out fractures (50.2%) were the most represented pattern, followed by zygomatic complex (46.5%). The most common symptom was hypoesthesia extending through the territory of the second trigeminal branch (TBH; 32.9%). Diplopia was present in 20.2% of patients followed by enophthalmos (2.3%) and extraocular movement limitation (1.7%). Ocular symptoms significantly improved following surgical repair. The most common postoperative complications included TBH in 34.2%, scarring 26%, and diplopia in 16.4% of the patients.

Metastases to oro-maxillo-facial region from distant sites: are they so rare? A single centre 8-years experience.

AIM: The goal of our study is investigate the frequency of metastasis to oro-maxillo-facial region to understand if they are really so rare. MATERIAL OF STUDY: In this eight year's retrospective study (2004-2012) we collected 15 cases of metastasis localized in the maxilla-facial region from distant primary tumor. RESULTS: Our results show breast and kidney as the most frequent primary site (40% and 20% respectively), adenocarcinoma as most common histological type (60%). Bone involvement has found to be much frequent than the soft tissue one (53.3%). The mandible (5/15 cases) is more affected than the maxilla, and most common interested subsites are molar and retromolar region. In our study we found only one case of unknown primary tumor, it was a mandibular bone metastasis from a renal clear cell carcinoma. CONCLUSION: Finally, according to our results and considering the increase of survival in cancer disease, even if metastases to oro- maxilla- facial region from distant sites are not frequent, it is important to suspect secondary lesions both in patients that was referred a tumor in their medical history and in those that present a head and neck lesion.

Parapharyngeal space benign tumours: our experience.

Only about 0.5% of all head and neck neoplasms occur in the parapharyngeal space (PPS) and approximately 80% of these tumours are benign lesions. Various surgical approaches some of which are associated with mandibulotomy to increase exposure have been described. This article describes our 16-years' experience in treating 60 PPS benign tumours with special focus on our surgical techniques intended to ensure adequate mass exposure and structure safety. On the basis of our experience we assert that mandibulotomy is currently not advocated in the surgical management of benign PPS tumours i.e. not even in very select cases. The transparotid approach is the treatment of choice for parotid gland lesions involving PPS and in cases of multinodular or uninodular pleomorphic adenoma relapse involving the PPS. The transcervical approach is suitable for the safe removal of even large PPS masses in most cases.

Metastatic uterine leiomyosarcoma in the upper buccal gingiva misdiagnosed as an epulis.

Uterine leiomyosarcoma (LMS) is a rare tumor constituting 1% of all uterine malignancies. This sarcoma demonstrates an aggressive growth pattern with an high rate of recurrence with hematologic dissemination; the most common sites are lung, liver, and peritoneal cavity, head and neck district being rarely interested. Only other four cases of metastasis in the oral cavity have been previously described. The treatment of choice is surgery and the use of adjuvant chemotherapy and radiation has limited impact on clinical outcome. In case of metastases, surgical excision can be performed considering extent of disease, number and type of distant lesions, disease free interval from the initial diagnosis to the time of metastases, and expected life span. We illustrate a case of uterine LMS metastasis in the upper buccal gingiva that occurred during chemotherapy in a 63-year-old woman that underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy for a diagnosis of LMS staged as pT2bN0 and that developed lung metastases eight months after primary treatment. Surgical excision of the oral mass (previously misdiagnosed as epulis at a dental center) and contemporary reconstruction with pedicled temporalis muscle flap was performed in order to improve quality of life. Even if resection was achieved in free margins, "local" relapse was observed 5 months after surgery.

Prosthetic rehabilitation in post-oncological patients: Report of two cases.

Prosthetic rehabilitation in post-oncologic patients after bone reconstruction are not substantially different than those of patients affected by severe atrophia of upper or lower jaw after bone reconstruction.Aim of this paper is to evaluate the possibilities of prosthetic rehabilitation on these patients and to present our method. Prosthesis-based oral rehabilitation of such tumor cases rapresents a challenge.The report analyses two cases of patients who underwent ablative oral surgery. Both have received a fibula free vascularised flap. The first was rehabilitated with a removable prosthesis fixed on the residual teeth, while the second with an implant supported prosthesis.In case of carcinoma resection of the oral mucosa, the removable prosthesis guarantees a simplification in dental care operations. On the other hand, irradiated mucosa is frequentely unable to tolerate the friction created by the acrylic base. However, the fixed prosthesis can limit the view during follow-up controls.In our school, according to all exposed reasons, we consider the implant supported overdenture prosthesis to be the best choice for those patients.
