[Traissac voice prosthesis. Apropos of 9 years experiences].

BACKGROUND: Long term results are discussed. PATIENTS: A retrospective study of 9 years (1/01/89, 1/01/98) concern 107 laryngectomized patients with 9 patients a part from this period, and 30% without prosthesis. Among 80 patients with prosthesis, 57% had received primary TEPs (tracheoesophageal puncture), 21% delayed primary TEPs and 22% secondary TEPs. Oesophageal voice is always learned with tracheoesophageal voice. RESULTS: We find a success rate (1 month) in 75% of cases, with a maximum follow up time of 8 years (the average is 3 years 1 month). We find a success rate with a long-term result in 66% of cases. Prosthesis removal exists in 30% of cases and oesophageal voice is successfull once out of 3 in this cases. Mean lifetime Traissac's prosthesis is 18 months. After removal, non closed fistulas can exist in 40% of cases, and surgery is always successful. DISCUSSION: Material Traissac's prosthesis explains extended lifetime. CONCLUSION: Traissac's prosthesis gave us satisfaction during a use of 8 years.

[Hypoparathyroidism after thyroid surgery].

The authors report their experience of hypoparathyroidism in thyroïd surgery: 538 patients underwent thyroidectomy, including 45% bilateral resections. In post operative period, accurate tests allowed to detect non permanent hypocalcemias in 60% of cases. Severe hypocalcemia (1.60 mmol/l) is necessary to engage a treatment by vitamin D. So, a soft thyroid microsurgery is the only one manner to preserve parathyroid stock. 46 patients had parathyroid transplantation, but the evaluation is difficult, because the amount of parathyroid gland without ischemia, left into the neck, is unknown. In summary, this technique is effective, but often useless in thyroid surgery.

[Isolated acute peripheral facial paralysis in children. Etiological and prognostic study].

BACKGROUND: As facial nerve palsy is usually of sudden onset and of obscure etiology, a survey of large series may provide new information. PATIENTS AND METHODS: The files of 40 children suffering from acute facial nerve palsy seen in 3 pediatric and 1 otorhinolaryngologic (ORL) departments between 1980 and 1990 were analysed. Patients with congenital palsy and those with paralysis that appeared after injury or in the course of acute or chronic disease (otitis media, tumor) were excluded from the study. The children were 9 months-16 years old (mean: 7 year 1 month). There were 22 left and 18 right facial nerve palsies. The palsy was moderate in 17 children, severe in 15, and total in 5. Etiologic factors (viral serologic studies, CSF examination), ORL studies and electromyogram of the facial nerve were analyzed in the majority of cases. Corticosteroids were used in 30 patients. RESULTS: A viral etiology was suspected and/or confirmed in 13 children; abnormalities were seen in 6 of the patients who underwent lumbar puncture. A familial facial nerve palsy was seen in 1 case and kidney disease in 2 cases. 23 cases appeared to be idiopathic. A moderate permanent residual weakness was seen in only 4 children. The mean time for recovery was 32 days (4-140 days). Corticosteroids did not influence the incidence of complete recovery, but decreased the time for recovery (26 versus 37 days) only in the patients who were treated before the 3rd day of the disease. Patients with idiopathic palsy recovered 23 days before those with viral etiology. CONCLUSIONS: Idiopathic and post-viral facial nerve palsies seem to have an excellent prognosis. Corticosteroids seem to have no effect although there is some evidence of benefit when treatment is begun early.
