[Cochlear implants in children].

The development of surgically implantable hearing aids that are placed directly in the cochlea where they send electrical impulses to the cochlear nerve is a major break-through for patients whose hearing loss is so severe as to make conventional electroacoustic hearing aids ineffectual. Initially used only in adults, this method has gradually been extended to pediatric patients. To benefit from a cochlear implant, the patient must fulfill a number of criteria which are specified in this article. Following preoperative investigations, the decision is taken during a meeting of all the care providers involved, i.e., the surgeon, ENT phoniatrist or audiophonologist, hearing aid specialist, special education provider, speech therapist, psychologist, and other members of the health care staff. Team work is thus essential both before and after the procedure. The implant selected can be intracochlear or extracochlear and single-channel (one electrode) or multi-channel (several electrodes). Each team selects the implantation technique and type of implant they use according to their preferences and specific criteria. The authors use a multi-channel intracochlear system except in the rare instances where complete ossification of the cochlea requires use of an intracochlear mono-channel system. They have inserted implants in 29 patients to date. The cochlear implant has unquestionably had a significant impact of the life of these patients.

[Severe aplasia of the ear: management and surgical indications].

Severe aplasia of the ear raises both a cosmetic and a functional problem. Surgery is often performed starting at four or five years of age but early management is essential. The need for a hearing aid should be evaluated at the age of six months. At birth, the infant should have investigations for concomitant malformations, which are common, and for etiologic factors. Functional surgery to create a canal, tympanic membrane, and chain of ossicles should be performed only in bilateral forms. Satisfactory cosmetic results can be achieved by cartilage autografting according to Brent's technique.

Clinical Protocols

[Current therapeutic indications in laryngeal stenoses in children].

Among pediatric patients with laryngeal stenosis, acquired forms are now more common than congenital forms. External surgery is not always warranted except in complete or tight obstructions. After establishing the diagnosis by endoscopy, consequences on respiration and phonation should be assessed before deciding on the most appropriate treatment: abstention, medical therapy, endoscopic treatment, or surgical treatment by the cervical route. Surgical laryngoplasty techniques have changed radically over the last twenty years. The Cotton procedure is the most widely used. Another available method is the cricoid-split technique. These laryngoplasty procedures can be performed from birth and tracheostomy is now warranted only after failure of initial surgery.

[Therapeutic strategy for cervicofacial lymphangioma in children].

The authors report a series of 22 cervicofacial lymphagiomas treated from 1984 to 1990, and try to define a therapeutic strategy. In 11 cases, facial, laryngeal or pharyngeal extension was observed, and 1 cas showed mediastinal extension. These cases are not easily treated, and it is impossible to perform complete surgery, thus leading to recurrence. Tracheotomy was necessary in two cases. In 5 cases, the extension was limited to the cervical area and surgical exeresis was considered complete. Sclerosing injections gave variable results.

[Value of cricoid split in congenital subglottic stenoses].

The authors report about the cases of two infants less than 5 weeks old, who presented with congenital subglottic stenosis and in whom a cricoid split produced good results. This procedure, which is classically reserved for difficult extubation of infants due to acquired subglottic stenosis, is compared with the other surgical techniques used in the congenital condition. It may be useful in the latter case owing to its simplicity and to the possibility of performing laryngoplasty later in case of failure.

Cricoid Cartilage

Indications of the carbon dioxide laser in tracheobronchial pathology of the infant and young child: 14 cases.

Fourteen children aged between 6 months and 7 years (mean age = 3.5 years) were treated by CO2 broncholaser in the ENT Department of Trousseau Hospital. Three groups of diagnostic indication were identified: 1. Granulomas treated after mucosal trauma (tracheotomy, foreign body). 2. Granulomas due to pulmonary and/or lymph node tuberculosis. 3. Adhesions and stenosis secondary to neonatal ventilation. The operative and anesthetic technique is described in detail, together with any possible adverse events. The CO2 broncholaser appears to be a technique of choice in this age group, in which the narrowness of the airways makes any endoscopic procedure difficult. The broncholaser allows the early treatment of obstructive tracheobronchial pathology with its risks of severe ventilatory sequelae.

[Development of tone curves in sensorineural deafness in children].

The authors reviews 239 cases of child sensorineural deafness (478 ears studied both separately and in correlation with the controlateral ear) to try and identify the evolutionary trend of the tone curves throughout the follow-up period, which spanned nearly 20 years in some cases. The difficulties encountered in this study were due to several factors, namely the problem involving very accurate assessment in very young children, the high incidence of tubotympanal disease in the very young, the hard to obtain definition and quantitative evaluation of the notion of progressiveness, as well as the need to analyze the evolutionary patterns in global terms (mean hearing loss), from one frequency to the next and from one ear to the other, since such tone loss patterns are not always symmetric. The authors state their opinion derived from a large number of cases regarding a situation, which characterizes a relatively frequent (over 25% of cases) aggravation of perceptive hearing loss in children.

Adolescent

[Hereditary epidermolysis bullosa and laryngeal involvement].

Two cases of epidermolysis bullosa (EB) with laryngeal involvement are reported in 2 Algerian girls, aged 6 and 7 years. The first one with a junctional EB, received local treatment with good results. For the second, with an EB dystrophica, tracheostomy was necessary and remained so. Laryngeal involvement is rare in EB. It and remained so can be serious and life-threatening. Eight cases where previously reported. Their clinical and therapeutical particularities are discussed.

[Protracted otitis and subacute mastoiditis in children. A prospective study apropos of 118 cases].

Antibiotherapy has lead to a substantial decrease in the number of infants with acute mastoiditis or complications thereof. However, the non-negligible incidence of protracted otitis currently observed has caused one to raise several pathogenid hypotheses, among which subacute mastoiditis figures as one needing to be detected early. This prospective study was conducted on 118 children treated for protracted otitis in the ENT Service at Hopital Trousseau, during the period from january 1987 to december 1988. It allowed us to develop diagnostic and therapeutic strategies to cope with the difficult problem of protracted otitis, taking into account bacteriologic findings and risk factors, among other things.

Adenoidectomy

[Otorhinolaryngologic involvement in cystic fibrosis].

ENT involvement is very frequent in mucoviscidosis, particularly rhinitis and sinusitis. This prospective study, which spanned from September 1st, 1988 to August 31st, 1989 anc included 27 children with cystic fibrosis of pancreas was carried out with the intent of determining the incidence of the various associated diseases, their bacteriologic profile, and the optimal therapeutic procedure. Less than a child in 5 is symptomless when the nose and sinuses are affected. Polyposis is found to occur in 6/27 cases, and all children have sinus radio-opacities. Ear disease is rare (1/4 of cases) and is manifested by asymptomatic tubal dysfunction with minimal audiometric repercussions. Bacteriologic specimens of sputum and sinus purulent discharge show simultaneous germ positivity (10 times out of 11). Our therapeutic recommendations are based on our own experience as well as literature data, and are, in our opinion, only relevant for children with clinical signs of disease, as opposed to advocating systematic treatment of sinus foci found on X-ray.

[The carbon dioxide laser in tracheobronchial diseases in children. A prospective study of 11 cases].

Carbon dioxide laser has been used in bronchology for over 15 years, primarily in adults and older children. With the recent development of appropriate bronchoscopes, one has now been able to extend its application to infants and small children. 11 patients, aged 10 months through 7 years, were treated by this technic at the ENT Service of the Hôpital Trousseau (Paris). Indications for broncholaser management at this age and the particularities thereof are specified, as well as the results obtained and the complications linked with its use. This new therapeutic tool appears to be reliable and effective in a certain number of cases, representative of which are circumscribed bronchostenoses, granulomas resulting from trauma or associated with tuberculosis, and benign tumors.

Bronchial Diseases

[Severe congenital laryngeal stridor. Endoscopic surgical treatment].

Congenital laryngeal stridor or laryngomalacia is a congenital disease causing an usually shrill and solitary inspiratory noise, sometimes associated with disorders of deglutition and dyspnea when crying. Most often, the symptoms spontaneously disappear before the age of two. However, some cases are very severe, with permanent dyspnea, leading to tracheal intubation or tracheotomy. To avoid the risks of prolonged tracheotomy in infants, a new surgical technique has recently been described, beside epiglottectomy and hyomandibulopexy, now abandoned. This is simple endoscopic section and resection of the ary-epiglottic folds. Preliminary results in 15 patients seem to show the superiority of this so-called epiglottoplasty technique. Except in one case with supraglottic oedema attributed to a major gastro-esophageal reflux, all patients recovered from their dyspnea with this procedure. Extubation usually was rapidly feasible and the post-operative period was uneventful. The patients are kept in hospital for 2 to 5 days, and an antibiotic and anti-reflux treatment is recommended. This procedure is advocated as a treatment of choice of "laryngomalacia" with severe dyspnea.

Dyspnea

[Surgical protocol of velo-palatal and labio-nasal clefts].

Based on a series of 52 cases of velopalatine and labionarinal clefts treated according to the same principle of therapeutic chronology, the authors define their recent surgical protocol for the primary repair of these clefts. Satisfactory functional repair of the tongue and platysma muscles of the face determine the good anatomical results and, in particular, the development of the maxilla together with the results on speech and middle ear pathology. Pathophysiological elements argue in favour of staphylorrhaphy as the first operative stage in unilateral labiovelopalatine clefts associated, at the same time, with cheilorhinoplasty; passive orthodontia is generally performed until the secondary palatoplasty. The surgical repair technique is closely related to this therapeutic timing in terms of the muscular and periosteal detachments.

[Conservative surgery of cancer of the larynx. Cordectomy, hemilaryngectomy, supraglottic laryngectomy].

Of a total of 219 partial laryngectomies performed, 119 were cordectomies, 30 hemilaryngectomies and 70 supraglottic laryngectomies. Results of each type of operation are presented with emphasis on problems of local recurrences, evidence of validity of procedure selected and of its indications. Analysis of results, with the reservation that indications were sometimes wide but always reasonable, showed an extremely low incidence of recurrences, the quality of the resection (limited or insufficient) having finally little incidence on the latter, except perhaps in the supraglottic laryngectomies. It is suggested, therefore, that no attempt should be made to "recover" a histologically detected insufficient excision by complementary radiotherapy not required in principle. This assists follow up review and allows secondary therapy if an unfavorable course is noted.

Adult

[Functional surgery of cancer of the hypopharynx. Hemilaryngopharyngectomy, posterior pharyngectomy by bilateral cervical approach].

The authors report on 48 patients operated by hemi-laryngo-pharyngectomy for spinous carcinoma of the piriform sinus. They try to precise the indications by analysing the factors influencing survival and relapses. They compare surgery to the other methods. In a second part, they report 3 cases of posterior pharyngectomy by bilateral cervical incision.
