[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.

[Conduction deafness and collapse of the auditory meatus. Value and limitations of the stapedial reflex in conduction deafness].

Collapse of the auditory meatus constitutes an audiometric trap provoking a false transmission deafness. It can also permanently affect audition, whether it be primary in origin or post-mastoidectomy. The association of conservation of the stapedial reflex and transmission deafness is noticed immediately, but this is in fact compatible with an interruption in the chain by incus luxation. These notions must be known in order to avoid operation in false transmission deafness, and inversely to decide when to explore the cavity in certain post-mastoidectomy sequelae with meatal collapse.

[Use of stereotaxic neurosurgery in the treatment of pain in cervicofacial cancers].

Mesencephalic tractotomy employing the stereotaxic method was conducted 12 times in 11 patients with pain due to cervicofacial cancer only partially relieved by high doses of opiates. Immediate results were spectacular in 10 cases and partial on the other 2 occasions. However, relief was not permanent even in patients in whom the greatest improvement was obtained, and the usual analgesics had to be prescribed after 3 months. The operation, which requires only a short period of anesthesia, was always well supported, complications being anesthesia of one side of the body in 2 patients and convergence paralysis in two cases, one of which was transient. Mesencephalic tractotomy constitutes a new weapon for the treatment of diffuse cervicofacial cancer pain not responding to major medical treatment. Elective thermocoagulation of the Vth and IXth nerves was also successfully employed for systematized pains.

[Post-traumatic cerebrospinal fluid rhinorrhea and otorrhea disclosing Mondini's syndrome].

A mild head injury could have played a role in the development of post-myringotomy cerebrospinal fluid rhinorrhea and otorrhea in an 18-month-old child with Mondini's syndrome. This notion of trauma may prevent exploration of the site of the fistula when these labyrinthic dysplasias are poorly understood. Once suspected, full radiological examination should precede closure of the gap using an otological approach.
