[Endonasal dacryocystorhinostomy].

Dacryocystorhinostomy an endonasal approach is a surgical procedure which permits removal of symptoms related to chronic stenosis of the naso-lacrimal duct without leaving external scars and without presenting risk for the orbital structures. The Author describes the surgical technique employed in 12 surgical cases. Use of the frontal loupe and of the operating microscope allows the surgeon's hands to remain free while all the advantages of binocular vision are maintained. Pre-operative investigation must always include a dacryocystography, a CT of the paranasal sinuses and an endoscopic examination of the nasal cavities.

[Echo-color Doppler and echo-Doppler in the diagnosis of carotid body tumors].

Echo-Doppler and Color Flow Doppler examinations, are able to combine the advantages offered by echography with those had with the Doppler exam. In the presence of tumours of the carotid body, these exams can furnish morphological data with regard to tumor size, its precise location and its rapport with contiguous organ as well as data regarding blood flow in the mass itself. The color Flow Doppler exam, in particular, can reveal the echographic aspect and the flow toward and away from the sonde all on the same image. This enables a precise diagnosis of a tumor of the carotid body to be reached even without angiography. The personal experience here reported involves ten cases observed during the last seven years.

[Relapsing polychondritis. Review].

Using a clinical case which was brought to their attention as a starting point, the authors reexamine the problems relating to the nosographic, etiological, pathogenetic, pathoanatomical and clinical aspects of relapsing polychondritis, as well as those concerning its differential diagnosis and therapy. In particular, they review the various theories of immunological pathogenesis related to the alterations in collagen observed in relapsing polychondritis and in other correlated diseases.

Jugular bulb diverticula.

Jugular bulb diverticula may extend either laterally in the tympanic cavity or medially towards the petrous pyramid close to the inner ear. In the first case, this leads to subjective symptoms related to the presence of a mass at the level of the tympanic cavity and the external auditory canal and thus to conductive hearing loss and pulsatile tinnitus. In the second case, vertigo, pulsatile tinnitus and sensorineural hearing loss occur. 4 cases of jugular bulb diverticula are described (1 medial type, 3 lateral type).

[High resolution computerized tomography in the study of traumatic pathology of the temporal bone].

Thirty-five patients with temporal bone fractures were examined; the fractures were sometimes associated with dislocation of the ossicular chain caused by road fatalities. Computed Tomography (CT) was performed either because of the presence of clinical symptoms associated with trauma of the temporal bone, or because of a hemotympanum discovered during a CT scan of the brain. Thirty-three fractures were detected: 19 longitudinal, 6 transverse, and 8 complex. An incudostapedial dislocation was also detected, together with a displacement of a stapedial prosthesis from the lenticular process of incus, and 3 incus-malleus dislocations associated with fractures. High resolution CT allows the precise definition of the course of the fractures, of the associated dislocation of the ossicular chain, and of facial nerve lesion, thus allowing a more accurate surgical intervention. In the examination of the temporal bone, high resolution CT is preferable to pluridirectional tomography because it is easier and faster to perform. Moreover, high resolution CT helps reduce the radiation dose, and yields higher-quality images with more accurate diagnostic information. High resolution CT also allows the brain and the temporal bone to be studied at the same time.

Atypical carcinoid of the larynx: case report.

The authors describe a rare case of laryngeal atypical carcinoid. They discuss the histologic pattern of the neoplasm and the differential diagnosis of laryngeal tumors, particularly with oat-cell carcinoma. These tumors represent a spectrum of neoplasms with endocrine differentiation.

[Relapsing polychondritis].

Relapsing polychondritis is a rare disease of unknown origin consisting in recurrent inflammatory episodes of cartilaginous structures as well as other organs such as the eye, the inner ear and the kidney. Symptoms of autoimmune or rheumatic disorders frequently precede those typical of relapsing polychondritis and thus the contemporaneous presence of these diseases is a common observation. Consequently some diagnostic concerns connected to the great variability of the early symptoms and also to the lack of a semiotic test do exist. It is widely recognized that a serious involvement of the tracheo-bronchial cartilage the lumen diameter with a consequent heavy dyspnoea which reduces occurs in relapsing polychondritis. In these cases the study of the thorax area by means of CT was of fundamental importance. Furthermore, histological analysis of bioptic specimens from tissues only apparently not affected, such as the pinna of the ears, better defines the nature of the disease. The Authors present a case report, characterized by the presence of a saddle-nose deformity as well as a dyspnoea caused by a lumen stenosis related to tracheo-bronchial cartilage chondritis.
