[Anatomical and functional evaluation 3 and 5 years later of 94 cases of chronic cholesteatomatous otitis media. Clinical and therapeutic implications].

Anatomical and functional results were evaluated at 3 and 5 years after surgery for chronic cholesteatomatous otitis media in 94 patients treated by the same surgeon between 1975 and 1983. Open techniques predominated and were justified by seven clinical or epidemiologic factors present alone or in association in 80% of cases. Many patients were non-attenders at follow up (40% at 3 years and 70% at 5 years), recovery from their cholesteatoma being noted in 84% and 78% of those attending at 3 and 5 years respectively. Useful audition was recovered in 52%, including 2 of 3 due to an open technique. Petro-mastoid hollow-out with arrangement of cavity and minimal ossicular reconstruction is considered the most effective treatment for this type of affection.

[Tympanic and jugular paragangliomas. I. Clinical symptomatology and evaluation of extension. Apropos of 25 cases].

Based on a review of 25 cases of tympanic and jugular paragangliomas treated and followed up in the Lariboisière hospital, Paris between 1978 and 1986, clinical aspects and extension of these tumors are studied. The often long delay in making the diagnosis is related to lack of knowledge of presenting symptomatology, frequent discordance between functional and physical symptomatology exists, but remarkable progress has been made in assessment of extension of tumors using new imaging techniques, particularly angiography, which can also guide the preoperative embolization and surgical procedures.

[Tympanic and jugular paragangliomas. II. Angiographic, surgical and irradiation treatment. Results. Indications. Apropos of 25 cases].

Results of treatment are reviewed in 25 cases of tympanic and jugular paragangliomas treated and followed up in the Lariboisière hospital, Paris between 1978 and 1986. Therapy has been transformed by the use of embolization but its non-negligible neurologic accident risks, whatever the carotid artery territory involved, justify prior weighing of indications for its application. New surgical technics allow more extensive exeresis, but intrapetrous extension to the nerve compartment of the jugular foramen and the anterior pericarotid region still raises difficult surgical problems and appears to be the principal reason for failure of treatment. Radiotherapy is very effective and applicable for inoperable forms, as a complement to incomplete surgical removal and for recurrences.

[Fibrous dysplasia and ossifying fibroma of the base of the skull. Apropos of 6 cases].

The authors report 6 cases of fibrous dysplasia (F.D.) of the base of the skull and review the literature. They confirm the impossibility of histological differentiation between ossifying fibroma and monostic dysplasia with cranio-facial sites. They stress the value of CAT scan in the assessment of spread and that of dynamic isotope scan in the differential diagnosis with plaque-shaped hyperostotic meningioma, in the diagnosis of polyostotic forms and in postoperative surveillance. They stress the risk of visual sensorial impairment: visual by stenosis of the optic canals and auditory by stenosis of the E.A.M. Operative indications are influenced by this risk, thereby explaining the need for prolonged surveillance.

[Olfactory esthesioneuroma. Clinical, histological and therapeutic aspects; apropos of 6 cases].

On the basis of 6 cases, the authors review the clinical, histological and therapeutic aspects of olfactory esthesioneuromas. These rare tumours, showing varying rates and degrees of progression from one patient to another, generally have a severe prognosis. Diagnosis is based upon precise histological criteria which may be clarified by electromicroscopic data. In difficult cases it may be useful to seek the aid of immuno-histochemical techniques in order to demonstrate the presence in tumour cells of specific neuronal enolase and the labelling of such cells by anti-protein S-100 antibodies. The treatment of choice would appear to be radio-surgical completed by chemotherapy similar to that used in neuroblastomas.

[Value of Gore Tex in the reconstruction of the nasofrontal canal].

Surgical technic used in treatment of chronic frontal sinusitis is described, and the interest emphasized of the employ of fragments of Gore Tex prosthetic fragments for calibration and maintenance of permeability of the newly formed nasofrontal canal. Their perfect tolerance allows them to be left in place and their permeability can be surveilled by CT scan imaging or fibroscopy.

[Approach to the pterygomaxillary region by the Lefort I osteotomy].

Approach to the pterygomaxillary fossa under the base of skull, a difficult operation, has been facilitated by the use of a technique derived from the Lefort I osteotomy. Satisfactory access to the fossa and to the posterior-base region is obtained and esthetic or functional sequelae avoided.

[Labial incompetence and maxillodental dysmorphosis].

A definition of labial incompetence is given and emptrasis placed on the fact that this is a symptom of maxillodental dysmorphism (MDD) and not of nasal dyspermeability. Pathogenic features are discussed, the relevant clinical and paraclinical diagnostic features of MDD outlined, and the different alveolodental and/or bony (maxillary or mandibular) dysmorphias responsible for labial incompetence described. Principles of orthodontic and surgical treatment are centered on re-establishment of a correct articulation and therefore labial competence.

[Mucoceles of the maxillary sinus. Diagnostic and therapeutic problems. Apropos of 5 cases].

Five cases of the rarely observed maxillary sinus mucocele are reported, one patient with bilateral lesions presenting primary dilatation of the bronchi. A previous history of surgery or injury to sinuses was obtained in all cases, the diagnosis being confirmed by computed tomography imaging. Recovery is usually complete after the Caldwell-Luc operation. One case with exclusion of the sinus is described and the literature reviewed.

[Diagnostic problems of tuberculoid cervical adenitis. Apropos of 70 cases].

Pathologic criteria in tuberculoid adenitis enable differentiation between follicular adenitis with or without caseous necrosis and that involving suppurative necrosis. The absence of specific etiology is emphasized. Seventy cases of tuberculoid adenitis are analyzed. Of the 62 cases of adenitis labelled tuberculous, bacterial confirmation was obtained in only 22 (35%), suggesting probable diagnosis by excess for the remaining 40 cases. Related bacteriologic problems concern isolation of B.K. of the 3 cases classified as sarcoidosis, it was important to obtain data from broncho-alveolar lavage and serum conversion enzyme assay. Four patients with adenitis were diagnosed as having cat-scratch disease from positive specific intradermal reactions, the probable discovery of the responsible agent thus providing a bacteriologic diagnosis.
