[Dermoid cyst of the floor of the mouth. A case report]. / Quiste dermoide de suelo de boca. Revisión a propósito de un caso.

This is the case of a young woman, 16-year-old, calling to our Department because of the appearance, in the floor of the mouth, of a mass progressively growing until about 5 cm diameter. Through fine needle biopsy was diagnosed of epidermoid cyst. Despite its size and infrahyoid site was removed successfully. Perusal review of last years bibliography and its variants.

[Neurinoma of the descending loop of the hypoglossal nerve. Report of a case]. / Neurinoma del asa descendente del nervio hipogloso. A propósito de un caso.

Neurinomata developed from extracranial portion of hypoglossal nerve are very scarce. We report one case of neurinoma originated in the descending branch of hypoglossal nerve and not having found after careful perusal of the literature of this subject another case we consider the ours as the first portraying this type of pathology and its localization.

[Pilomatrix carcinoma of the face. Two case reports]. / Carcinoma pilomatricial con localización facial. A propósito de dos casos.

Pilomatrixial carcinoma is the malignant variety of pilomatrixoma. It is a malignant lesion, locally aggressive that can reappear, specially if not completely removed. Scanty are the number of cases listed in the literature (2). Although metastases are uncommon one or twice references can be found in the writings (1). We report 2 cases of pilomatrixial carcinoma located in the middle canthal and malar zones, which were treated surgically: excision of the tumor and reconstruction by means of a local rotation flap.

[Infective stomatitis of the palate]. / Localización palatina de las estomatitis infecciosas.

Having on base a wide and selective review of the literature, it has seemed to us interesting to detail the infective pathology on this location or sometimes occurring. This region is, as well will see, the seat of a rich pathology. We pretend on the other hand to reassess the importance of the meticulous examination of the oral cavity in "systemic problems". We describe the palatal infections divided in four groups: bacterial, viral, fungal and parasitory, according to the causal agent. We review the palatine manifestations of other fewer current syndromes as well.

[Reconstruction of a palatal defect with pedicled myomucosal flap of buccinator muscle]. / Reconstrucción de defecto palatino con colgajo miomucoso pediculado de buccinador.

The myomucosal flap from buccinator muscle is a versatile flap useful on reconstruction of defects located in the palatine region. We report the case of a vascular tumor located in the left palate which was removed and rebuilt with a myomucosal flap taken from buccinator muscle. We proceed previously to the embolization of its nutritional artery (a. palatina major).

Carcinosarcoma of the submandibular and sublingual salivary glands. A case report and review of the literature.

Carcinosarcoma of the salivary gland is a rare lesion, estimated at 0.2% of malignant salivary gland tumors [1, 2]. The present article describes a case occurring in a 54-year-old man with a submandibular mass in the right neck. Histologically, this lesion was a carcinosarcoma which involves the submandibular and the sublingual glands. Its stromal component was a chondrosarcoma and the epithelial one was an undifferentiated carcinoma in the whole tumor, with areas of adenoid cystic carcinoma in the sublingual gland. To our knowledge, we have not found any previously reported carcinosarcoma involving the sublingual gland.

Blunt internal carotid artery trauma: report of two cases and review of the literature.

Blunt injury of the internal carotid artery (ICA) is a rare entity that should be considered by Maxillofacial surgeons in patients with facial fractures. Its recognition is often delayed because of the common association with other severe multi-system injuries. Early diagnosis is the key to successful management; the arteriography plays a confirmatory role on the diagnosis and determines whether surgical management of the injury is feasible. Therapeutic alternatives vary from one center to another; they include observation, conservative treatment, anticoagulation, ligation of the carotid artery with or without extracranial-intracranial bypass, and arterial reconstruction.

Mediastinitis as a rare complication of an odontogenic infection. Report of a case.

Mediastinitis occasionally develops as a complication of cervical or odontogenic infections resulting in neck sepsis, which spreads to the mediastinum via the cervical facial planes. Nowadays, this rare complication of pyogenic orofacial infections has an high-unchanged mortality rate. Delayed diagnosis and inadequate mediastinal drainage are the primary causes of this high mortality rate. Aggressive empirical antibiotic combinations should be directed towards this polymicrobial process. Antibiotic therapy alone is inadequate and the mainstay of treatment is aggressive surgical drainage through cervical and thoracic approaches. The assessment and management of the airway is critical; most authors recommend early tracheostomy in a controlled fashion in all cases of serious neck infections with or without thoracic involvement. However, we consider tracheostomy not always necessary and we only perform it in patients with severe dyspnea from upper airway obstruction.

Chronic diffuse sclerosing osteomyelitis of the mandible or mandibular location of S.A.P.H.O. syndrome.

The chronic diffuse sclerosing osteomyelitis (CDSO) of the mandible has been described as an inflammatory disease characterized by recurrent episodes of intense pain in the mandible, often accompanied by trismus, paresthesia and progressive mandibular deformity. The etiopathogeny of this entity is not fully known. The differential diagnosis must be carried out very carefully, and the treatment results are very disappointing. Recently, evidence that suggests that CDSO may be the mandibular location of a more diffuse condition, the synovitis, acne, pustulosis, hyperostosis, osteitis (SAPHO) syndrome, has been offered. We describe two clinical cases of CDSO of typical evolution which fulfill the criteria for SAPHO syndrome, offering us an occasion for a review of the current literature.

[Report of 3 cases of adenoid cystic carcinoma of the palate. Clinical, histological and therapeutical considerations]. / Presentación palatina del carcinoma adenoide quístico. Características clínicas, histológicas y terapéuticas.

Three cases of adenoid cyst carcinoma of the palate are reported. In this study clinical features, pathological findings, treatment and prognosis are analyzed. In the 1st and 2nd cases we unfortunately verified that the course of the tumors based in a slow-continuous infiltrating spread. Moreover, in our first patient a late diagnosis of it made the prognosis become worse. In the 1st one, radical surgery is proposed for the adenoid cyst carcinoma diagnosed at an early stage without tumoral dissemination.

[Diffuse sclerosing chronic osteomyelitis of the mandible]. / Osteomielitis esclerosante crónica difusa de la mandíbula.

Diffuse sclerosing chronic osteomyelitis is a lasting pathological entity characterized for recurrent outbreaks of intensive pain referred to the mandible, escorted with inflammatory phenomena, trismus, paresthesia of the nervus alveolaris inferior and progressive deformity of the lower jaw. The differential diagnosis with other facial neuralgies of the face must be very carefully get up and its treatment is disappointing. The etio-pathology of the illness remains uncertain. The AA. report one clinic case with typical course, which offer them the opportunity to review and discuss the literature of the subject.

[A free forearm flap in reconstructive maxillofacial surgery. Surgical technic and results of 40 clinical cases]. / Le lambeau antébrachial libre dans la chirurgie réparatrice maxillo-faciale. Technique opératoire et résultats de 40 cas cliniques.

The authors report their experience of microsurgical reconstruction of the maxillofacial region with the radial forearm flap in 40 patients. After a brief historical and anatomical description, the cases are presented and specific considerations on the author's operative technique are detailed. The discussion on the advantages and the disadvantages of this flap ends the paper.

[Antebrachial free flap with radial pedicle. II. Surgical technique]. / Le lambeau libre antébrachial à pédicule radial. II. Technique opératoire.

The authors detail the anatomical, physiological, and clinical considerations of the free forearm flap. These characteristics determine the many indications of this flap in the maxillofacial surgical reconstruction. Contraindications are quasi inexistent. The second part of this work analyse the surgical and microsurgical operative technique use for the authors. All different parts of this work are discussed upon a deep review of the recent literature.

[The role of microsurgery in the reconstruction of loss of substance of soft tissue in the maxillofacial region]. / Le rôle de la microchirurgie dans la reconstruction des pertes de substance des tissus mous de la région maxillo-faciale.

Reconstruction of oncological defects in the maxillofacial region still remains a real surgical challenge due to the complexity and the tridimensional aspect of these defects responsible for heavy functional impairment. Microsurgery allowing the transfer of free flaps gives the surgeon the opportunity to adapt a specific reconstruction to each defect and to reinsert the patient in a quasi normal social life. These reconstruction technics are routinely used in many centers; they must be integrated in our therapeutic arsenal and in the training of the maxillofacial surgeon. Seven years ago, we incorporated microsurgical reconstruction in our therapeutical concepts and today, it seems to us important to share our experience of microsurgical reconstruction in the field of soft tissues defects in the maxillofacial region.

[Calcifying odontogenic epithelial tumor (Pindborg's tumor). Review of a case with maxillary localization]. / Tumor odontogénico epitelial calcificante (tumor de Pindborg) Revisión a propósito de un caso localizado en el maxilar superior.

We report a case of maxillary sitting of a calcifying odontogenic epithelial tumor (Pindborg's tumor). It is a benign tumor with similar microscopical findings with the ameloblastoma although its natural evolution is different. The tumor has an actodermal odontogenic origin. The stem cell from which it develops and its growth stimulus are unknown. Although the intermediary stratum of the enamel producing organ has been incriminated. A swelling of the maxillae or a casual finding--as the case reported--are the most common manifestations at beginning of these cases. The differential diagnosis depends on the radiological pattern we may find. Various surgical procedures may be considered optional. It could vary from enucleation to complete resection of the affected structure. Aggressive surgery is not indicated.

[Orbito-fronto-temporal approach to tumors at the base of the skull. Our experience in the creation of orbito-zygomatic-malar flap]. / Abord orbito-fronto-temporal des tumeurs basicrâniennes. Notre expérience dans la création d'un volet orbito-zygomatico-malaire.

The authors describe the technique of mobilization of the osseous orbito-zygomatico-malar complex pedicled to the masseter muscle. In some affections it is justiciable to use this approach which provides an excellent view of the lateral region of the medial cranial fossa and orbit and permits the access to the base of the tumor by a intra- and extracranial approach without traumatic injury for the brain and easy reconstruction.

[Mandibular reconstruction using a free vascularized fibular flap]. / Reconstruction mandibulaire par transfert libre de péroné vascularisé.

The authors report their experience with the free osseous and osteocutaneous fibular flap used in the complex mandibular reconstruction. After a short review of the mandibular reconstruction possibilities and description of the fibular flap characteristics, the clinical cases are reported and the operative technique used by these authors is detailed. The discussion of the advantages and the disadvantages of this flap in the complex mandibular reconstruction ends the paper.
