Pneumosinus dilatans frontalis : a case report
No full textDeformity of the forehead is usually the first clinical presentation of the abnormally large frontal sinus caused by pneumosinus dilatans. We report the diagnosis and surgical treatment of a case. The type of osteotomy we describe is recommended as a method of surgical treatment for this condition when the aesthetic problem is the major complaint
Minimally invasive arthroscopy of the temporomandibular joint
No full textAim. The purpose of this study was to present a new method for treating internal derangement of the temporomandibular joint (TMJ) using a minimally invasive arthroscopy. The authors describe the technique, discuss the indications and evaluate the clinical outcome.
Methods. We performed minimally invasive arthroscopy as initial surgical procedure in 48 consecutive patients (35 female and 13 male) with unilateral TMJ dysfunction and joint pain not responding to nonsurgical treatment and magnetic resonance evidence of internal derangement. After the procedure, nonsteroidal antiinflammatory drugs, intensive phisiotherapy, soft died and interocclusal appliance were prescribed. A clinical examination with analysis of Maximal Mouth Opening, a Visual Analog Scale (VAS) and a self-administered questionnaire were used for evaluation of pain, jaw dysfunction, and activities of daily living (ADL). The follow-up period was 1 year.
Results. Diagnosis of intra-articular pathology was made and it was possible to stage all the patients following Wilkes classification. There were no complications related with minimally invasive arthroscopy. At 1-year follow-up, maximal mouth opening had increased significantly. Functional improvement was associated with a significant reduction in VAS, pain, dysfunction and ADL score. The overall success rate was 83,3%.
Conclusion. The results indicate that minimally invasive arthroscopy is an affective treatment improving function and reduction pain in patient with internal derangement of the temporomandubular joint. It could be considered as a first step in surgical cascad
Low-grade myofibroblastic sarcoma of the oral cavity
No full textTwo cases of low-grade myofibroblastic sarcoma (LGMS) are presented: one of lateral tongue, the other of lower buccal vestibule. LGMS represents a distinct atypical myofibroblastic tumor that occurs in several sites, primarily within the head and neck regions. A painless, enlarging mass is the most common clinical presentation, but a definitive diagnosis requires both histopathological and immunohistochemical analyses. Histologically, LGMS commonly presents as a cellular lesion composed of spindle-shaped tumor cells arranged primarily in fascicles with a diffusely infiltrative pattern. Immunohistochemically, LGMS shows positive staining for at least one myogenic marker, such as desmin, and muscle actin

Alveolar distraction in post traumatic mandibular atrophy : report of two cases
No full textThe main indication to use vertical alveolar distraction is post-traumatic mandibular atrophy. This technique allows to obtain an adequate bone volume for insertion of osseointagrated implants. The authors present in this article two patients cases in whom alveolar vertical distraction was applied to atrophy post-traumatic, using endoral twin track distraction. In both cases it was prepared a stereolithography model to mimic the box of the bone to be distracted, to align the preoperative distractor and to obtain the more effective carrier. At the distractive stage followed the implant prosthesis stage which was designed to rehabilitate the previously atrophic bone area. In both patients it has been possible to insert the planned number of implant
Arterial microanastomoses on the reverse flow of the internal carotid artery reverse flow: an extreme solution in free-flap revascularisation : how we do it
No full textMicrovascular free tissue transfer in head and neck reconstruction requires suitable recipient vessels, which are frequently compromised by prior surgery, radiotherapy, or size of the tumour. A surgical description of an arterial free flap pedicle anastomosis on the reverse internal carotid arterial flow in a vessel-depleted neck is presented. A 66-year-old male with a relapse of hypopharyngeal squamous cell carcinoma previously treated with both surgical and radiation therapy for carcinoma of the tongue and the larynx was successfully reconstructed using a free forearm flap with reverse internal carotid arterial flow. The involvement of the carotid glomus and prior surgery excluded the other vessels as recipients. The forearm free flap survived without any complications. This procedure can be considered an alternative rescue technique for salvage reconstruction in a vessel-depleted neck
