Surgical functional reconstruction after partial maxillectomy with fibula free flap. A bilateral upper alveolar bone, gingival and palatal defect after tumor resection, has various problems originating from reconstruction with prosthesis or temporalis muscle flap. We report a secondary reconstructive procedure using the fibula osteocutaneous free flap. The combined bone segments created the upper alveolar arch, and the skin paddle closed the palatal defect. This procedure restored the patient to masticatory function of the upper jaw, intelligible speech and natural facial appearance. As a result quality of life of patient was extremely improved.
Oral malignant melanoma is a rare lesion; overall prognosis remains poor despite more radical surgery with adjuvant radiotherapy chemotherapy and immunotherapy. This article describe the therapeutic approach in two cases of malignant melanoma of the hard palate. The surgical treatment provides an "en bloc" resection of the palate and of the upper alveolar crest with clear margins. The use of orthognatic surgical procedures with an oral access avoids cutaneous incisions and affords conservative but complete resection.

Neoplastic spreading by seeding occurs through mechanical transfer of some cells from a tumor mass onto healthy tissue of an implantation site. There is significant experimental proof of neoplastic cells seeding in surgical wounds although this seldom occurs in cases of surgery for head and neck tumors. We consider the description of a squamous cell carcinoma of the tongue which spread to the tracheotomy site, most probably through a iatrogenic seeding and conclude that use of a few simple precautions could minimize the frequency of such unfortunate complications.
The authors present a case of a rare type of odontogenic tumour, recently described as "clear cell odontogenic tumour". The patient died 5 years after the initial diagnosis with lymph node and diffuse pulmonary metastases. This fact can support the view that this tumour, histologically characterised by the presence of cells with a clear cytoplasm, can behave in an aggressive way and has true metastatic potential, despite the absence of malignant cellular features.
Access osteotomies allowing temporary displacement of various segments of the orbital rim provide direct visualization of deep orbital and paraorbital regions. These marginotomies are classified, according to the orbital region involved, as lateral, medial, superior, or inferior, and they provide adequate exposure of the corresponding orbital wall and its surrounding structures. Since these procedures are without complications and cause no unpleasant cosmetic effects, they are highly recommended for the treatment of various lesions in this area as well as for correction of malformations.
The treatment of maxillary deformities in edentulous patients, with reference to tooth-bearing ones shows some differences concerning both the treatment planning and the surgical procedures. The Authors present in detail their way of planning the treatment and some expedients and modifications they apply to the usual surgical procedure in this special kind of maxillary deformities.
A case of mandibular leiomyoma in a 8-month-old baby is reported. This is the 5th case of intrabony leiomyoma of the jaws reported so far. The tumor presented as a symptomless swelling of the mandibular ramus and required a limited resection. The pertinent literature is reviewed and the histological features discussed.
In the treatment of the severely damaged TMJ structural components (ankylosis, arthrosis, tumour, perforation or degeneration of the disc), it is advisable to insert a biological interposition between bony articular surfaces. The temporal muscle, due to its anatomical, topographical, and functional properties, can be successfully employed for this purpose. Based on the experience of Tessier, Delaire and Rowe, a temporalis muscle flap, inferiorly based, is rotated downwards and medially to the zygomatic arch, interposed and then fixed to condyle and capsule. Using this surgical technique, 12 patients and 13 temporo-mandibular joints were treated with good functional results and without any complication.
The authors present a rare case of developmental anomaly called regional odontodysplasia. It is also called odontogenic dysplasia, ghost teeth. It is a disorder that affects both the ectodermal and mesodermal dental components. The teeth usually fail to erupt and they have wide pulp chambers. Any teeth may be affected, but the disease is usually restricted to single quadrants. The cause is unknown.
Aggressive juvenile fibromatosis is not metastasizing disease characterized by a neoplastic proliferation of fibroblasts that rarely involves surrounding bone. The Authors describe one case observed by them and suggest the surgical procedure as elective treatment of the disease. In cases where a mandibular resection is performed, a simultaneous bone reconstruction, when feasible, is indicated.
The maxillo-malar osteotomy is one of the osteotomies developed over the years to correct the deformities of the midface without modifying the nasal projection. After having for many years approached the osteotomy through the classic double access, intraoral and subciliary, we verified the feasibility of this osteotomy via an intraoral route only. For this purpose we modified slightly the classic osteotomy lines, however still including in the mobilized fragment the most prominent and therefore the most aesthetically important portion of the zygoma. At the lower orbital rim the medial osteotomy cut is performed with a fissure bur, the lateral one with an oscillating saw. Both the osteotomies are extended posteriorly in the orbital floor with a fine osteotome. Then, after having performed all other osteotomy cuts, the maxillo-malar complex is down-fractured. The residual thin bone structures which connect the maxillo-malar complex to the cranio-facial skeleton are broken during a careful downfracture, avoiding fracture between the maxilla and zygoma. The complex is advanced and stabilized with intermaxillary fixation, osteosynthesis and bone grafts. A bone graft to the orbital floor is unnecessary.

The sinusal osteomas: a review of literature and personal cases. The osteoma is a osteogenetic benign tumour formed by a fully developed bone, characterized by a slow growth, which, as far as the maxillo-facial region is concerned, shows to be frequently located in the paranasal sinuses. The osteoma originates from one of the sinus walls and spreads into the sinus cavity itself producing symptoms related to a lesion space occupying. In the present report, taking into consideration 4 personal cases, some literature datas are examined concerning the epidemiology, clinical behaviour and especially the therapeutic implications to be adopted by the surgeon in the presence of sinusal osteoma.
