Surgical treatment of Graves' disease.

Seven men and 81 women were operated on for Graves' disease. Their median age was 33 years. Eleven patients underwent a bilateral subtotal lobectomy; 77 patients underwent a complete lobectomy with contralateral partial lobectomy. Forty-seven patients were treated before 1981. In these patients, the weight of the thyroid remnant was estimated empirically between 5 and 12 g. In the 41 patients treated since 1981, the remnant weight was estimated at 5 g by comparative weighing. There were no postoperative deaths. Functional results were established in 83 patients with an average follow-up of 50 months (range 12 to 156 months), with control of vocal cord mobility demonstrated by indirect laryngoscopy in 66 patients. Hormonal determinations were carried out in 74 patients. There were no cases of permanent hypoparathyroidism. Three patients (4.5 percent) had unilateral vocal cord dysfunction. Twelve patients (14.5 percent) had clinical and biologic hypothyroidism, which occurred within 1 year postoperatively in 11 cases. Seven patients (8.3 percent) had latent hypothyroidism only discovered by hormonal determinations. Fifteen patients (17.8 percent) had recurrent hyperthyroidism, 6 of whom were diagnosed by hormonal determinations. The actuarial recurrence rate increased progressively up to the sixth postoperative year. The only predictive factor for recurrence was the type of operation. Patients who underwent a bilateral subtotal lobectomy had more recurrences than patients who underwent a complete lobectomy with partial contralateral lobectomy (p less than 0.01). These results suggest that patients should be followed closely for many years and should undergo hormonal determinations regularly, as some recurrences can occur 5 years or more after operation with very few symptoms.

[Surgical correction of saddle nose. Apropos of 23 cases].

Choice of graft for repair of a saddle nose in 23 patients, usually late sequelae of nasal fracture, varied with degree of concavity : moderate anomalies usually by cartilaginous graft, major lesions by iliac bone graft. Postoperative course was always simple. The Rethi approach was used when a bone graft was necessary, with a minimum esthetic ransom, and a skin flap of V-Y advancement at the expense of the white labrum when there was insufficiency of columellar height. Although results were assessed as satisfactory by the patients, the difficulties in obtaining excellent results in this type of rhinoplasty are emphasized, imperfections being frequent : filling of nasofrontal angle, asymmetry of naries orifices and fixed nose appearance.

[Use of coral implants in maxillofacial and otorhinolaryngologic surgery].

The coral, as bio-compatible implant, has been used in several indications: in Otology: for ossicular chain and external auditory canal reconstruction. In Maxillo-facial surgery: for orbital floor, maxillary sinus and jawbone reconstruction. The first results of this study are favorable but coral resorption might be prevent by a careful sealing of the implant deep under the surface layer.

Choanal atresia and deafness.

Nine cases of bilateral choanal atresia are reported. The association with other malformations and deafness is evaluated. The choanal atresia is associated with multiple malformation in two cases and bilateral deafness in 5 cases. Before discussing surgery, a complete evaluation has to be performed, deafness has to be evaluated with modern electrophysiological methods. The risks of the surgery should be considered in case of cardiac malformation and cerebral anoxia.

[Anatomy of the choanae in the newborn].

The choanal atresia is a congenital malformation and his surgical procedure need to clarified. Ten anatomical specimens have been studied by anatomical measures and CT scan evaluation of the choanal for amend. Our study allow us to predict before surgery the maximum dimension of the choanal opening. A large opening seem to prevent choanal atresia recurrences.

[Limits of auditory evoked potentials of the brain stem in the diagnosis of deafness in children].

117 children were examined in Gatien of Clocheville during 13 months. In the same session behavioural audiometry and brainstem auditory evoked response audiometry were performed. With the click technique: BSAER do not identify tonal notchs. The BSAER threshold is higher than the behavioural threshold because low frequencies are not explored in profound deafness. It is difficult to differentiate conductive and perceptive deafness when wawe I is missing. Within these limits BSAER is powerful test in babies and children with behavioural disorders.

[Cholesteatoma of the external auditory canal].

Epidermal plugs of the external auditory canal were described initially by Toynbe in 1850, and since that time epidermal plugs and canal cholesteatomas have often been classified under the same heading. However, auditory canal cholesteatoma represents a separate clinical entity, although its pathogenicity remains unrecognized. Therapy may be medical or surgical, but a more eclectic therapeutic approach is to be preferred. Two recent cases of auditory canal cholesteatoma are reported.

[Auditory-evoked brainstem potentials and stapedius muscle reflex: intersubject variability].

Like other workers, we found gender differences in auditory-evoked brainstem response latencies. For the time being, this intersubject variability remains unexplained. This difference was observed only for wave V latency, and delta I-V is longer in men than in women, whereas delta I-III is identical. The absence of functional differences in the lower portion of the auditory tract is confirmed by both auditory-evoked brainstem potentials and stapedius reflex latency. Wave V latency and the influence of technical and anatomical factors are discussed as well.

Auditory brain stem responses and cortical auditory-evoked potentials in difficult-to-test children.

Brain-stem-evoked responses (BERs) and cortical auditory-evoked potentials (AEP) were recorded in 24 children showing severe behavioral disorders. BER testing always requires sedation if not general anesthesia. This allowed us to perform precise acoustic impedance measurements, and thus to find 3 glue ears. The electrophysiological tests revealed whether there was sensorineural deafness, which was cared for if necessary. Finally, when the BERs were normal, we evaluated the modifications in the cortical AEP, in relation to a clinical classification closely related to that of the DSM III of the American Academy of Psychiatry.

[Clinical manifestations of various mycoses of the upper respiratory and digestive tracts in African pathology].

Mycotic infections are prevalent in tropical Africa, and are sometimes observed North and South of this zone, but they are usually localized to the lower limbs (mycetoma), without manifestations in the ORL sphere. However, various ubiquitous superficial mycoses are also encountered in Africa, particularly Aspergilloses and Candidoses. Their clinical expression (apart from several cases of pseudo-tumoral sinusal aspergillosis...) differs only slightly from that observed and treated everywhere, and they are not discussed. Also excluded are several cases of North-American Blastomycosis reported North and South of the Sahara (Blastomyces Dermatidis). Their ORL manifestations do not appear to have been studied. Three very well known major forms remain: Histoplasmoses, Rhinosporidiosis, Phycomycoses (or Rhino--Entomophtoroses). Sporotrichoses with nasofacial manifestations may also, perhaps, be included.

[A rare paraneoplastic syndrome: Bazex' syndrome (author's transl)].

The authors report a case of Basex' syndrome in its typical and complete form of the cutaneous syndrome, appearance of the skin lesions preceding the pharyngeal symptoms. The squamous cell carcinoma confirmed by histopathological examination was treated by radiotherapy only.
