General remarks on carotid-ophthalmic aneurysms are followed by the description of a personal case in which direct closure of an "inoperable" aneurysm was successful. The surgical treatment of these malformations is discussed.
Four basic steps should be considered in craniofacial tumor surgery: dismantling and re-assembling of preservable bone structures to reach the tumor; en bloc resection of the "box" in malignancies (i.e., the unaffected boundaries surrounding and including the tumor), internal rigid fixation and, reconstruction by using whenever possible regional structures. In benign tumors and so-called pseudotumors, the treatment is total removal and immediate reconstruction of all structures, including the bone. The primary goal of craniofacial surgery for malignancies is to create an entrance to the box that is to be resected. This necessitates the dismantling and reassembly of some uninvolved skeletal structures. Among these are the nose, the maxilla, the nose and maxilla en bloc, the nose and the maxilla bilaterally to the mandible. The introduction of internal rigid fixation by using plates and screws has facilitated the realignment of the pedicled bone fragments in a correct position. After cranial base resection, the communication between neuro- and splanchno-cranium must be closed with viable flaps. Many techniques have been described. The horizontal forehead flap is certainly effective but results in a significant secondary defect. Where there is an orbital resection en bloc with the cranial base, the temporalis muscle flap is effective in providing vascularized coverage and simultaneously obliterating the orbital cavity. The galeal frontal flap is versatile and easy to use. It has been used to cover anterior and lateral defects with good results. The orbit is another area that requires immediate reconstruction so that there is no resulting external defect. The temporalis muscle flap, with or without a skin island, can be used to repair it. Distant flaps can likewise be used. If the resection includes the maxilla, reconstruction of the defect can be performed immediately, or it can be delayed. The authors prefer to use the temporalis muscle flap if it has not already been used. On the basis of 10 years of experience in craniofacial surgery the following conclusions can be drawn: 1. Craniofacial surgery is not a single concept. Therefore, the surgeon who deals with facial tumors involving the cranial base must have expertise in the entire field. Oncology must be part of his basic biological education. 2. Complications functional and aesthetic consequences are minimal if some basic principles are applied, both in the resection and the primary reconstructive phase. 3. In the past few years, surgical techniques have been modified and improved considerably, resulting in an operation that combines an excellent approach, oncological resection, low postoperative morbidity, good aesthetic results and improved prognosis.
Fractures of the occipital condyle occur very rarely. Plain cervical spine films are not able to detect them. Tomography and CT scan of atlanto-occipital joint are, in these cases, very important. The Authors report a case of a young girl who had a head trauma associated to a fracture of the right occipital condyle. The value of CT and tomography are emphasized.
The posterior approach to cervical rizopathy is a widely acquired technique; however only recently it encountered more favorable consideration. After a brief review of the literature, the Authors present some details of surgical approach, discuss its value and its limits with a comment on their own series.
Craniobasal tumors affecting the middle cranial fossa are rarely treated radically; the main problem to solve is the presence of important nervous and vascular structures in this region. The Authors report a case of complete removal of a malignant tumor involving the temporal bone and the middle cranial fossa. Surgery was performed by the cooperation of the neurosurgical and the ENT teams.
Two cases of an unusual complication in ventriculo-peritoneal shunt for childhood's hydrocephalus are described. Migration of the distal part of shunt into peritoneal cavity was observed. Symptomatology, diagnostic and treatment are reported.

In this paper we report a series of 9 patients with ACA aneurysms successfully operated on. Their incidence, anatomical location, clinical signs, surgical approach and results are reviewed.
Breathing abnormalities in patients affected by acute cerebral damage are herein studied as neurological signs of localizing value for the neurological diagnosis of the level of the lesion. Incidence and types of abnormal breathing pattern correlate with neurological syndromes, and in a given neurological syndrome the presence of these alterations entails a more severe outcome. Tachypnea shows the most significant correlations from a diagnostic and prognostic point of view.
