The role of dental canal fillings in the development of Aspergillus sinusitis. A report of 85 cases.

Radiopaque concretions in the maxillary sinus in cases of sinusitis are often observed in infections with aspergillosis. For several authors, such features are considered to be typical of these infections. For us this foreign body in most cases is believed to be related to overfilling of the teeth. We have previously drawn attention to this fact. We report 85 cases of aspergillosis of the maxillary sinus. Cases involving immunosuppressed patients were excluded because of very different clinical conditions. A radiopaque foreign body was seen in 94% of the cases. Of this group, 85% were believed to be related to overfilling of maxillary teeth with dental paste, particularly since evidence for endodontic treatment was found in the premolar/molar region. An image of intrasinus dental paste was demonstrated in 12% of the cases as a direct extension of filling paste from affected teeth. The nature of the dental paste is important because the zinc contained can stimulate the growth of Aspergillus fumigatus. In vitro studies in our laboratory also showed that the growth of A. fumigatus was stimulated with a low concentration of zinc.

The infratemporal fossa: a trial clarification.

The contents of the infratemporal fossa have been studied using CT scans, anatomical dissections and radiography of the anatomical specimens. On the strength of this, 3 distinct regions are discernable: the anterior part of the fossa contains the fat pad of the cheek and this area corresponds to the retromaxillo-zygomatic region; the region of the pterygoid m. contains vascular structures and lies behind the preceding region; the pterygopalatine fossa, formerly considered the deepest part, extends the infratemporal fossa superiorly and medially. These anatomical and radiographic findings could serve as a guide to maxillo-facial surgeons dealing with expanding lesions within the infratemporal fossa, or invading it from adjacent regions.

[Malformation of the facial canal, meningitis and cerebrospinal otorrhea].

CSF fistulas into the middle ear due to labyrinthine or tegmental anomalies are well known. They predispose to recurrent meningitis if they do not receive appropriate surgical treatment. CSF fistulas due to facial canal anomalies are extremely rare and predispose to the same risk of meningitis. The case reported enables a comparison to be made with the three other cases of the same form of anomaly found in the literature, and the diagnostic and therapeutic difficulties are also discussed.

[Dermatologic facial surgery in patients over 70 years of age. Apropos of 166 cases surgically treated in 1986 and 1987].

For patients pass the age of seventy, the facial dermatologic surgery can be often practised, under local anesthesia, during an hospitalisation of one day (111 cases under 121). The technic of repair in two times is systematically applied for the sclerosing basal cell carcinoma; this technic allows a best performance of excision and diminishes the risk of recurrence.

[Intrapetrous carotid aneurysm and tube prosthesis. Apropos of a case].

The introduction of a tubular prosthesis such as that described by J. Wright in 1976 is sometimes proposeD to ensure ventilation of the ear at the time of tympanoplasty. A case of ruptured intrapetrosal internal carotid aneurysm is reported, apparently related to the presence of such a prosthesis. The occurrence of such an accident should question the use of a tubular prosthesis in an inflamed ear. Endovascular trapping by balloon catheter would appear to be the most effective treatment for this form of ruptured intrapetrosal aneurysm.

[Perilymphatic fistula. Diagnostic and therapeutic difficulties].

The symptoms and signs of perilymphatic fistulae (PLF) are very varied and frequently misleading. The operative demonstration of a perilymph leak is not always obvious and the therapeutic results are sometimes disappointing. The study of 26 cases demonstrates certain concepts concerning the diagnostic and therapeutic difficulties. Any atypical cochleovestibular symptoms, particularly occurring in a traumatic context, should suggest the possibility of PLF. Exploratory surgery must be performed according to a rigorous protocol in order to demonstrate the fistula. Search for a fenestra ovalis sign due to pressure on the membrane of the fenestra rotunda may help to reveal a lesion of the annular ligament. Simple filling of the breach is not always effective, especially at the level of the stapes. Stapedectomy frequently constitutes the best solution for fistulae of the fenestra ovalis.

[Aneurysmal cyst of the petrous bone. Apropos of a case].

Aneurysmal bone cyst (ABC) is a rare form of osseous dystrophy. A lesion of the petrous temporal bone appears to be extremely rare. It must be differentiated from a hemangioma which is a hamartoma affecting the geniculate ganglion or the internal auditory meatus. The case described involved a 23-year-old woman. The ABC presented with violent otalgia and severe endolabyrinthic-type perception deafness. It was associated with extensive bony destruction of the petrous temporal and occipital bones. Curettage only led to considerable through temporary regression of deafness and bone reconstruction within a few months. Thrombosis of the internal jugular, confirmed at operation, is an interesting contribution in terms of the pathogenesis of ABC, apparently linked to disturbances of venous pressure. Surveillance is required since this benign condition may be recur.

[Limited mandibular osteoradionecrosis. Early conservative surgical treatment].

Nine patients with early phase mandibular osteoradionecrosis received conservative treatment involving closure with mucosal and periosteal graft. Early intervention and the limited nature of the osteoradionecrosis are the two fundamental elements for a successful outcome to this conservative therapy, thus avoiding progression to an extensive form requiring interruption mandibulectomy.

[Flaps in the reconstructive surgery of dermatologic epitheliomas of the nose (excluding rhinopoiesis). Apropos of 144 surgically treated cases].

Dermatologic epithelioma of the nose is usually a basocellular and more rarely a spinocellular epithelioma. Small tumors less than 5 mm in diameter can be treated by electrocoagulation, whereas those over 1 cm should be treated by surgery or physical methods. Of a total of 144 cases of epithelioma operated upon, 10% were reconstructed by a flap. Increasing use is being made of local anesthesia with subsequent reduced hospital stay. The quality of the carcinologic results, similar to that of physical methods, and the excellent healing obtained, particularly in elderly patients, are arguments in favor of extensive surgery for epitheliomas in this region. The quality of the resection is difficult to evaluate, unless results of a fresh specimen examination are available. When not possible then it is preferable to await results of histology to show limits of excision before performing an autoplasty with flaps.
