[The cochlear aqueduct and congenital perilymphatic fistula. An initial report].

The authors present 3 preliminary case reports of congenital perilymphatic fistula and describe their approach, which in the presence of clinical symptoms composed of progressive or fluctuating deafness, should suggest the diagnosis of congenital perilymphatic fistula leading to examination of the cochlear aqueduct by high resolution computed tomography. An anomaly detected on the CT scan, particularly on the intermediate and internal segments, is a decisive argument in the decision to operate on these congenital perilymphatic fistulae.

[Our current experience with subglottic hemangioma in infants. Apropos of 29 new cases].

The authors report 29 cases of sub-glottic hemangioma in infants. Symptomatology was dominated by laryngeal dyspnea and the diagnosis was made on direct laryngoscopy. The symptomatology and endoscopic appearance enabled two groups to be distinguished: non obstructive hemangiomas (11 infants) and obstructive hemangiomas (18 infants). For non obstructive hemangiomas, the authors recommend close surveillance in combination with short term steroid therapy was prescribed from the start. In the event of failure of steroid therapy (8 infants) naso-tracheal intubation and selective embolization was carried out and gave the best results. In 4 infants failure of the above treatments led to tracheostomy.

[Surgical treatment of severe laryngeal stenoses in children].

This article constitutes a short review of the experience of the ENT service at the Hôpital Bretonneau, in Paris, with regards to laryngeal stenosis in children. Since 1974, 115 cases of severe stenosis have been operated on. 70 cases presented acquired lesions, primarily related to endotracheal intubation, while congenital malformations accounted for another 45 cases. 41% of the patients had stenosis that reduced the laryngeal lumen by 90%, or more. The different surgical approach (consisting in castellated incision of the anterior wall, or in anterior, or more rarely posterior, cartilage supplementation), as well as the various stenting methods used are briefly described and discussed.

[Anatomic characteristics of the mastoid in children. Pneumatization of the subfacial region].

Three specific features of the mastoid in the pediatric population appeared to us to be important in view of our per-operative findings on mastoidectomy for chronic suppurative otitis, cholesteatoma or middle ear effusion with chronic persistent mastoiditis in the older child. These included the position of the facial nerve, the superficial nature of its third part being well known, but also the existence of the Körner septum and especially the pneumatization of the sub-facial region which explains the similarity between certain infectious lesions of the retro-tympanic structures and infectious lesions of the anterior portion of the mastoid process. An experimental study of staining of preserved petrous bones in the adult enabled the sub-facial permeability of the mastoid to be demonstrated in certain cases. Awareness of these small details should help to avoid per or post-operative complications in surgery for chronic otitis media in children.

[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.

[The association of megaesophagus, Binder's syndrome and dysautonomia: a new neurocristopathy].

A case of esophageal achalasia is reported in a 12 year-old child. Nasal hypoplasia (Binder syndrome) and dysautonomia were associated. This may be explained by the common embryologic origin (neural crests) of nasal bud, autonomic nervous system and digestive intramural neurons. Such a neurocristopathy suggests exploration of the autonomic nervous system in cases of esophageal achalasia.

[Cervicofacial lymphangiomas in children].

Of 41 children, 22 girls and 19 boys, with cervicofacial lymphangioma, 31 had congenital lymphangiomas, 30 lymphangiomas with cervical expression but only 9 were restricted to the neck region. Operation in 35 children showed that in 12 cases the lymphangioma was limited in extent and failed to extend to the neck or parotidojugular region, and excision was complete and there were no recurrences. Partial excision was performed in 23 children in whom the lymphangioma extended to various degrees into the tongue, pharynx or larynx, and tracheotomy was necessary in 10 of these cases. Several operations, and particularly endoscopic resections, are often necessary in this type of dysembryoplasia in order to obtain a sufficient airway. Esthetic results are often disappointing.

Treatment of infantile subglottic hemangioma. A report of 49 cases.

Forty-nine laryngeal subglottic hemangiomas were observed in infants over a 9-year period. The diagnosis was always confirmed by direct laryngoscopy. The outcome of 42 of these hemangiomas was studied. A total of 26 infants recovered completely after medical treatment and 16 were intubated; only 4 underwent a tracheostomy. Short-term steroid therapy was sufficient in 7 infants, but long-term administration of corticosteroids was necessary in 14 cases. In 10 of the 16 intubated cases it was possible to withdraw corticosteroids permanently. Of the 6 remaining cases, 32P contact radiation therapy was tried in 2 cases of which one was successful, CO2 laser in 2 cases without success, tracheostomy alone in one case and one child died 2 months after extubation, without dyspnea. This series leads us to recommend corticosteroids as a first therapeutic step and short-term nasotracheal intubation if unsuccessful.

[Laryngitis in newborn infants. Apropos of 3 cases].

Laryngoscopic examination of new-born infants with laryngeal dyspnea or dysphonia usually reveals a congenital lesion, but true infections laryngitis, although rare, does still exist. Three cases are reviewed and the literature searched. Functional laryngeal signs are non-pathognomonic, all three levels of the larynx may be affected by inflammation, and pathogenic agents may be viral (herpes), bacterial (Haemophilus Para-Influenzae) or mycotic. In two of the cases reported confirmation of diagnosis was by local swab under laryngoscopic guidance. Recovery occurred after medical treatment alone and intubation was not required in any of the three patients. These findings emphasize the value of laryngoscopy with swab in all neonates with dyspnea or dysphonia in an infectious context.

[Myringoplasty in children].

An anatomical success rate of 81% was obtained in 150 children 2 to 15 years of age operated upon by myringoplasty in the hospital Bretonneau, Paris between 1977 and 1984. Results were unrelated to age the season or the condition of the mucosa. Adverse factors were a previous history of a transtympanic aerator, a velar cleft or bilateral perforations. Mean functional gain after 1 year was 14 dB. It was not related to age or the technique used.

[Congenital glottic-subglottic stenoses].

One particular form of congenital stenosis of larynx that should be considered as a separate entity is the combination of a glottic stenosis with subglottic retraction. The salient features of this malformation are analyzed in 15 cases: laryngeal dyspnea with dysphonia in 2 of 3 patients and the possible detection of a subglottic anomaly on lateral radiography of larynx. However, confirmation of diagnosis can only be by laryngotracheoscopy. It is important to establish a diagnosis of subglottic stenosis associated with a palmation, since treatment and prognosis are very different from those of an isolated glottic palmation: all attempts at endoscopic treatment resulted in failure that intubation or tracheotomy was necessary in 7 cases. One of the 3 fatal cases was directly related to lack of detection of the subglottic stenosis. A successful laryngoplasty was performed in 10 children.

[Laryngeal anomalies in newborn infants. Apropos of 687 cases].

Congenital laryngeal anomalies are a frequent cause of obstructive dyspnea in neonates and young infants, and raise diagnostic and emergency treatment problems. Clinical symptomatology includes stridor of variable severity, obstructive dyspnea and deglutition disorders, but a less typical picture may be seen of apnea, cyanotic episodes, bradycardia and even cardiac arrests. A retrospective study of 687 case-reports of infants treated between 1974 and 1983 was conducted. Lesions included essential congenital laryngeal stridor (laryngomalacia) in 378 cases (50%), of which 15% were severe with respiratory distress and/or deglutition disorders; laryngeal palsy in 161 cases (23%), bilateral in 56 and unilateral in 105 cases; laryngeal incoordination in 23 cases; laryngeal stenosis: 79 cases (11%) including 58 subglottic and 18 dysphragmatic stenoses and 3 atresias; subglottic hematoma: 49 cases; ary-epiglottic or glosso-epiglottic cyst: 15 cases; laryngeal diastema: 11 cases; and bifid epiglottis: 1 case. Clinical, radiologic and endoscopic findings, and the principal therapies used, are discussed for each anomaly.

[Rare tumor of the cavum (mycosis fungoides)].

A case of mycosis fungoides initiating in the cavum is reported. Results of biopsy of specimens taken from this region were negative, and diagnosis was established only after the appearance of lymph node and cutaneous lesions. The etiology is discussed, particularly in relation to the possible viral nature of the acquired immunodeficiency sundromes and more especially the "gay syndrome".

[Riedel's thyroiditis. Apropos of a case with acute massive fibrous development].

Before a brief historical review of the disease, including its classical diagnostic criteria, the authors present a true case of Riedel's thyroiditis. After an initial operation involving virtually complete excision of the affected lobe, the course was particularly rapid with very extensive cervical fibrosis which resulted in death from tracheal and oesophageal complications. Such rapidly progressive secondary fibrosis has not been described before and did not have the histological characteristics of a recurrence. The authors liken it to phenomena of fibrosis frequently described as being associated with Riedel's disease (retroperitoneal fibrosis, fibrosing cholangitis, orbital pseudotumour, etc.). Bearing in mind that glucocorticosteroids have a beneficial action on such sites, the authors wonder whether routine preoperative corticosteroid therapy might not have avoided such an early fatal outcome in this patient.

[1-stage operation in major aplasias of the ear. Value of combined plastic and functional intervention].

In spite of imperfections, combined functional and plastic surgery is of value of treating major aplasias of the ear. The two operative procedures can be performed by the same surgeon or the same team when the child has reached 5 to 6 years of age. The technique involves the use of sliding pedunculated flaps, with rotation in the auricular region, and the employ of conventional otologic microsurgical methods (homograft, moulded temporal aponeurosis). Results in 48 cases demonstrated auditory improvement of more than 20 decibels in 47-5 p. cent of cases, and 30 to 40 decibels in 20.8 p. cent.

[Choanal imperforation in children. Value of the transpalatine approach. Apropos of 30 cases].

Two routes of approach, the transnasal and the transpalatine, are used with equal frequency to treat choanal imperforations in infants, the transpalatine approach being traditionally reserved for children over 1 year of age. A retrospective study of 30 children treated between 1974 and 1981 demonstrated that results were insufficient when the transnasal approach was used (80 p. cent failures) when compared with those obtained with the transpalatine approach (90 p. cent successful). A suggested explanation for the superiority of the transpalatine approach is advanced, and this approach route proposed for initial surgery during the neonatal period based on the results of recent experimental studies showing its safety with regard to maxillary growth.

[Comparative study of the significance of lymphadenopathy in carcinomas of the hypopharynx, larynx and epiglottis. 574 cases].

The significance of the absence or presence of lymphadenopathy is not the same in relation to the site of the primary tumour. This study involved 574 cases, including 213 carcinomas of the piriform fossa and 361 laryngeal carcinomas, and revealed errors of omission (No - N+) in carcinomas of the piriforme fossa (50% cases) and the possibility of errors of commission (N not equal to - N - in carcinomas of the larynx. This merely confirmed the high level of lymphatic affinity of carcinomas of the piriform fossa, but at the same time emphasised the relative reliability of the clinical assessment of relevent classifications.
