Surgical planning in reconstruction of mandibular defect with fibula free flap: 15 patients.

The authors present a descriptive work on the reconstruction of large oromandibular defects with revascularized fibula free flaps in a group of patients treated by surgical resection of bony and soft tissues of the mandible. The principal objective is preoperative planning for the best morphological, functional, and aesthetic result. The authors report 15 reconstructions of wide oromandibular defects by revascularized fibula free flaps. The average patient age was 42 years. The mean follow-up period was 18 months. Correct surgical planning reduces surgical timing, minimizes the chance of failure during the reconstruction, and contemporaneously increases treatment efficacy and the best functional and aesthetic results.

Intraoral distraction of a patient with premaxilla agenesis.

The complex disharmonies which affect the maxillofacial region, in the sagittal and vertical dimensions, can find further complications due to the deficit of maxillary osseous tissue in transversal direction. Surgery can be indispensable to correct the malocclusion. Various methodologies have been developed for the correction of transversal maxillary hypoplasia. Among these, the Authors mention the intraoral distraction for the treatment of a male patient with pre-maxilla agenesis and serious contraction of the upper maxillary. A particularity of this case is represented by the occurred transversal skeletal expansion, starting from a past scar, outcome of a previous surgery.

Central nervous system mesenchymal chondrosarcoma.

Central nervous system mesenchymal chondrosarcomas are rare malignant tumors that constitute a separate entity from the classical chondrosarcoma and myxoid variant. Clinical behaviour of central nervous system chondrosarcomas is still unknown. We describe two rare examples of intracranial mesenchymal chondrosarcoma with a review of the literature, in an attempt to clarify the clinical characteristics, prognosis and treatment of choice of these unusual tumors. Among the 55 reported cases, 23 had postoperative radiotherapy. Although there is no statistical significance according to the Log-Rank test (p=0.7), the patients treated with radiation therapy seem to have a better chance of survival. Patients who had adjuvant chemotherapy (only 5) showed survival times similar to those patients who had none. Although clinical behaviour of central nervous system chondrosarcomas remains to be defined, data from our series as well as literature show that radical removal is the best therapeutic choice. In addition, patients treated with postoperative radiotherapy seem to show a trend toward increased survival.

Unusual vascular hamartoma of the hard palate. A case report.

Hamartomas are tumour-like malformations usually present since birth or which may develop during puberty. Hamartomas are related to anatomical development errors. Hamartomas are rarely found in the head and neck district. The case of an unusual vascular hamartoma localised in the hard palate of a 50-year-old female with no significant medical or family history is reported. Surgical treatment was performed by means of an excisional biopsy.

Spinal intradural endodermal cyst located anterior to the cervical spinal cord.

Spinal endodermic cysts are rare and may be associated with other congenital anomalies (mediastinal cysts, bony defects of the vertebral body), derive from defective displacement of the endoderm of the intestinal tract or, more rarely, the respiratory one. The authors describe a case of endodermic cyst of the cervical spine localized anteriorly to the spinal cord. In the case we treated the patient was a 17-year-old male who presented hypostenia of the lower limbs accompanied by hyperreflexia and spasticity; physical examination was negative. MRI, CT and CT-myelography documented a well-defined mass situated anteriorly to the spinal cord at C2-C4 level. A total-body CT-scan excluded the existence of other malformations. Surgery was performed via an anterior approach and the cyst completely removed. Histological examination confirmed the endodermal nature of the cyst. At long-term follow-up examination the patient was neurologically intact. Postoperative MRI showed a small residue of the cyst wall without spinal cord compression. Endodermic spinal cysts are very rare intradural lesions, predominantly with an anterior cervical localization, which derive from misplaced embryonic and endodermic cells. In the majority of cases, clinical onset is insidious and has a discontinuous progression. The best diagnostic tool is MRI. Treatment of choice is total surgical removal or emptying of the cyst followed by fenestration.

Cervical synovial cysts: case report and review of the literature.

The authors describe the case of a 58-year-old man with a 6-month history of severe myelopathy. CT scan and MRI of the spine revealed a cystic formation, measuring about 1 cm in diameter, at C7-T1 at a right posterolateral site at the level of the articular facet. At operation the mass appeared to originate from the ligamentum flavum at the level of the articular facet and was in contact with the dura mater. Once the mass had been removed, there was a significant amelioration of the patient's symptoms. As previously suspected, histological aspect was synovial cyst. Cervical synovial cysts are extremely rare and, as far as we know, only 22 cases have so far been described in the literature. Diagnostic radiological investigations used were CT scan and MRI. At CT scan the most important diagnostic findings are a posterolateral juxtafacet location of the mass, egg-shell calcifications on the wall of the cyst, and air inside the cyst. At MRI the contents of the cyst are iso/hypointense on T1- and hyperintense on T2-weighted images. There may also be a hypointense rim on T2-weighted images, which enhances after i.v. administration of gadolinium. Surgical treatment consists of removal of the mass. Fixation of the vertebral segments involved is not always necessary.

Anterior clinoidal meningiomas: report of a series of 33 patients operated on through the pterional approach.

Between 1985 and 1995, 33 cases of clinoidal meningioma were surgically treated by pterional approach. In 6 cases, according to the grading scale of Al-Mefty, the lesions were group I, having originated from the lower part of the clinoid; in 22 cases, the lesions were group II, having originated from the upper or lateral part of the clinoid process; and in 5 cases, the lesions were group III since they arose from the optic foramen. Postoperatively, 17 patients showed an improvement, 4 were unchanged, and 6 presented further deficits. Five patients died after surgery: two from pulmonary thromboembolism, one from myocardial infarction, one from hematoma of the operative field, and one from cerebral ischemia after severe vasospasm of the internal carotid artery (unresponsive to treatment). The mean follow-up was 53.7 months (range 12-108 months) and included 19 patients. During this period, there were five recurrences, and three patients underwent resection again and showed no signs of tumor regrowth 1 year later; one patient who did not undergo resection again due to his age and poor general conditions died 3 years after onset of the recurrence; the last patient has so far refused a second operation. The clinical, diagnostic, and therapeutic aspects of this not infrequent pathology are discussed in the light of our experience and the pertinent literature.

Orbital hemangiopericytoma: case report of a long-term recurrency.

Among tumors concerning the orbit, hemangiopericytoma is one of the most unusual forms. This tumor has a vascular origin and usually appears as a fleshy, well-circumscribed mass, characterized by slow growth and lack of soreness. Its biological traits include a mostly benign nature, a potential malignancy, and, most of all, a highly frequent recidivation. This study of double recidivation shows this can occur even after a long lapse of time and the new tissue can acquire malignant traits. Finally, we describe the modes of the surgical approach, which aims at intervening the most radical cases to reduce recidivation to a minimum.

Paranasal sinus mucocele: diagnosis and treatment.

Several controversies still exist regarding the etiopathogenesis, diagnosis, and type of surgical treatment used in response to paranasal sinus mucocele. We wish to contribute to the standardization of therapeutic treatment for paranasal sinus mucocele by reporting our clinical experience in "open surgery." This analysis considers 53 patients--23 males and 30 females (age range: 11-80 years)--affected by frontoethmoidal or sphenoidal sinus mucocele whom we have surgically treated. Patients were classified according to age, sex, previous surgical treatment in the nasal area, symptoms, and acute visual difficulties; 15 patients showed disease in the frontal area, 28 in frontoethmoidal area, and 10 in the posterior ethmoidal or sphenoidal area (or both); in 18 patients the disease had reached the intracranial region. Transfacial approaches were used in all patients who did not show evidence of disease in the intracranial region. Of all the incisions performed 18 were coronal, 16 were paralateral, and 4 were through upper eyebrow approaches; a transnasal endoscopic approach was used in only 1 patient in whom the intracranial region was affected by disease. All patients showed satisfying functional and aesthetic results during and after recuperation.

Cervical locked facet: operative management.

Cervical locked facet represent 5.6% of cervical lesion. If an identity of views is present in the use of tractions, we can't say as for the setting fixation techniques. Our cases histories (13 cases) and the experience of other authors incline us to support a precocious surgical treatment characterized by a posterior approach and then anterior in the not reduced cases and a single anterior approach in the reduced cases in anesthesia. The good alignment and the attain stability with the double access, but still more the convinction that the lesions of intervertebral disk and ligamentous tissues (as demonstration at the RMN) is always to remove, support us in the undertaken therapeutic attitude.
