[Evaluation of an educational intervention on the standard of neonatal resuscitation: orotracheal versus nasotracheal intubation]. / Quelle technique d'intubation enseigner dans un programme de formation à la réanimation en salle de naissance : voie orotrachéale ou nasotrachéale ?

UNLABELLED: Proficiency in endotracheal intubation is an essential step in the neonatal resuscitation process. This skill is difficult to acquire and its mastery requires experience. Recent changes in neonatal resuscitation guidelines (ILCOR 2006) have resulted in a decrease in the opportunities to practice intubations. Appropriate education and training is therefore essential. The goal of this study was to assess the skills of neonatal care professionals in performing intubation via orotracheal (OT) and nasotracheal (NT) routes. METHODS: OT and NT intubation attempts were compared during training on a neonatal mannequin (Laerdal, Neonatal Resuscitation Baby((R))) at each course of an educational intervention on neonatal resuscitation organized in level 1-3 institutions of the Maternités en Yvelines Perinatal Network. The duration of these attempts was noted; intubation in less than 30s was considered successful. RESULTS: Thirty-two midwifery students (STD), 103 midwives (MW) and 25 pediatricians (PED) participated in the study. The median (IQR) time for intubation was less with the OT route than with the NT route for STD (12.0 vs 23.0s; p=0.001), MW (14.0 vs 25.0s; p=0.001), and PEDs (13.0 vs 20.0s; p=0.007). The success rates for intubation in less than 30s were higher for the OT than the NT routes for STD (100% vs 66%; p=0.001), MW (97% vs 69%; p=0.001) and PED (92% vs 88%; p=NS). CONCLUSION: This study confirms that OT intubation training resulted in a higher success rate and lower duration for intubation. Practical courses in neonatal resuscitation should include training with OT intubation.

Inlay butterfly cartilage tympanoplasty in children.

OBJECTIVE: To assess the results of inlay butterfly cartilage tympanoplasty in children. STUDY DESIGN: Before-and-after trial; follow-up duration, 26.6 +/- 19.9 months (mean +/- standard deviation). SETTING: Tertiary referral center. PATIENTS: Fifty-nine pediatric cases of tympanic membrane perforation. INTERVENTION: Inlay butterfly cartilage tympanoplasty was performed under general anesthesia according to the technique originally described by Eavey and modified by Lubianca-Neto (i.e., without any associated split-thickness skin graft). MAIN OUTCOME MEASURES: Percentage of perforation closures, surgical complications, preoperative and postoperative puretone hearing thresholds; the results of inlay butterfly cartilage tympanoplasty were compared with those obtained in a retrospective series of 29 underlay fascia temporalis myringoplasties. RESULTS: The 71% "take rate" of inlay butterfly cartilage tympanoplasty was not significantly different from the 83% take rate obtained with underlay fascia temporalis tympanoplasty (p = 0.23, chi test). The anatomic results were improved when the graft diameter was at least 2 mm larger than the size of the perforation (81% take rate) (p = 0.009, chi test). No iatrogenic cholesteatoma was observed. Pure-tone hearing thresholds were improved at 0.5, 1, and 2 kHz, and stable at 4 kHz. Hearing levels were not different from those obtained with underlay fascia temporalis tympanoplasty. CONCLUSION: Inlay butterfly cartilage tympanoplasty is a safe, efficient, time-saving, and easy technique of tympanoplasty in children. Anatomic results may be improved by associating a split-thickness skin graft and/or by trimming a tragal graft much larger than the size of the perforation.

[Laryngotracheoplasty reconstruction with four-quadrant cricoid division in children]. / Laryngotrachéoplastie avec quadrisection du cartilage cricoïde chez l'enfant.

UNLABELLED: Four-quadrant cricoid division in laryngotracheal reconstruction is indicated in case of very tight laryngotracheal stenosis. The principle of this operation is to section the anterior, posterior and lateral walls of the cricoid and to increase the diameter of the laryngeal lumen by interposition of a cartilaginous graft in the anterior and/or posterior cricoid wall. MATERIAL AND METHODS: From 1991 to 2001, 25 children underwent a laryngotracheoplasty with four-quadrant cricoid division. Two techniques were used: a single-stage procedure with a 10 days post-operative intubation (n=6), or a two-stage procedure with prolonged post-operative intraluminal stenting and tracheostomy (n=19). RESULTS: In the two-stage procedure the decannulation rate was 89% (17/19) after the first operation, and 100% after revision surgery using the same technique. In the single-stage procedure the extubation rate was 83.3% (5/6). CONCLUSIONS: Laryngotracheal reconstruction with four-quadrant cricoid division gives excellent airway patency especially in case of severe subglottic stenosis with altered laryngeal mobility. The single-stage procedure decreased the tracheostomy related morbidity. This technique is particularly adapted to children under three.

Cartilage tympanoplasty for posterosuperior retraction pockets of the pars tensa in children.

OBJECTIVE: To assess the functional and anatomic results of cartilage grafting in children with a severe retraction pocket of the posterosuperior part of the pars tensa and operated on by pocket excision and cartilage grafting. STUDY DESIGN: Retrospective case review. SETTING: Tertiary referral center. PATIENTS: Fifty six children (60 ears) with severe posterosuperior retraction pockets. INTERVENTION: Excision of the pocket and tympanic reinforcement with a tragal or conchal cartilaginous graft. MAIN OUTCOME MEASURES: Postoperative anatomic (otoscopy, computed tomography) and functional (pure tone audiometry thresholds) outcome. The follow-up time was 27 +/- 18 months (mean +/- SD). RESULTS: Retraction recurrences requiring additional surgery occurred in 5 cases (8%). The risk of recurrence was lower in children older than 10 years and when the whole surface of the pars tensa was reinforced (chi(2) test, p< 0.05 for both factors). Functionally, hearing was improved even when the ossicular chain was intact. In case of disrupted ossicular chain, direct contact between the graft and eroded incudostapedial joint gave good hearing results. CONCLUSIONS: Cartilage reinforcement of the whole surface of the pars tensa is probably the best treatment of a severe posterosuperior retraction pocket. The flexibility and thinness of cartilage from the cymba conchae makes it particularly suitable in this indication.

[Acute external mastoiditis in children: report of a series of 48 cases]. / Mastoïdites aiguës extériorisées de l'enfant: à propos d'une série de 48 cas.

DESIGN: To determine the impact of the emergence of penicillin-resistant strains of pneumococci on the frequency of acute mastoiditis in children, and to assess the importance of laboratory and imaging studies in the treatment of acute mastoiditis. METHOD: Retrospective review of the medical records of children with postauricular swelling and otoscopic signs of acute otitis media from January 1993 through December 2000. RESULTS: Forty-eight children aged three months to 14 years (median 17 months) were identified. The number of cases was almost the same from one year to another. All children had bacteriological examinations. The mastoid pus and the otorrhea was sterile in 22 cases. The most frequent pathogen was Streptococcus pneumoniae (17 cases), which was resistant to penicillin in 71% of cases. The initial body temperature, the number of polymorphonuclears and the CRP were not different between the group of 18 children with periostitis, which required medical treatment alone, and the group of 30 children who had a mastoid abscess which required surgery. The difference between periostitis and mastoid abscess was seen on clinical examination and CTscan.

Congenital nasal pyriform aperture stenosis: diagnosis and management of 20 cases.

The objective of this study was to review the characteristics of congenital nasal pyriform aperture stenosis (CNPAS) in a series of 20 children seen between 1993 and 1996. The diagnosis was made by physical examination and computed tomography scan. A single central maxillary incisor was detected in 12 cases (60%). Three children had morphological abnormalities of the pituitary gland shown on magnetic resonance imaging. One child had an antidiuretic hormone deficiency, and another child had a growth hormone deficiency. Two children had craniosynostoses, 1 of which was Apert's syndrome. All patients underwent operation by a sublabial approach, and 1 was referred for a columellar necrosis after nasal stenting. After surgery, all patients showed improvement, and the nasal stenting was usually removed 1 week after surgery. Follow-up revealed normal breathing. In conclusion, CNPAS was previously considered to be an unusual cause of nasal obstruction in neonates and infants. The number of cases treated recently in our department suggests that this newly recognized entity is more common than expected.

Surgical removal of subglottic hemangiomas in children.

OBJECTIVE: To examine the indications and the results of surgical excision of severe subglottic hemangiomas. DESIGN: Retrospective study and case series. SETTING: Four academic tertiary care centers of pediatric otolaryngology. PATIENTS: Twenty children were included from 1991 to 1997. All presented with severe subglottic hemangiomas resistant to classical treatments such as corticosteroids and/or CO2 laser. INTERVENTION: Six children were operated on using laryngotracheal reconstruction and prolonged stenting by a reinforced Silastic roll and 14 children were operated on by a single-stage laryngotracheoplasty and postoperative intubation in a pediatric intensive care unit. RESULTS: All patients were successfully decannulated or extubated and have been free from recurrent hemangiomas. CONCLUSION: The surgery of severe subglottic hemangiomas is a reliable technique in selected patients and should be considered in corticoresistant or corticodependent, circular, or bilateral hemangiomas.

[The value of orbital ultrasonography in ethmoid sinusitis in children]. / Intérêt de l'échographie orbitaire dans les ethmoïdites de l'enfant.

PURPOSE: To assess the value of orbital sonography (US) compared to CT in the management of children with ethmoid sinusitis. MATERIAL AND METHODS: A total of 13 consecutive patients admitted for non-complicated ethmoid sinusitis (absence of visual or neurological symptoms) were prospectively evaluated at US and CT. RESULTS: Three patients had no evidence of postseptal involvement at US. Ten patients had variable degree of postseptal involvement at US: hypoechoic area or fluid collection in the extraconal fat along the medial orbital wall. Results were confirmed at CT in all patients. CONCLUSION: US is useful to confirm the presence of postseptal involvement in patients with ethmoid sinusitis. Contrary to CT, findings at US remain non-specific as to the nature of involvement. Nonetheless, US is helpful for patient management.

[Surgical management of laryngeal stenosis in children]. / Traitement chirurgical des sténoses laryngées de l'enfant.

Surgical management of children with laryngotracheal stenosis changed recently because of the procedure of single-stage approach. Between January 1992 and April 1997, 101 children underwent surgery for laryngotracheal stenosis in our department: 47 of them had a single stage procedure, and 54 a classic laryngotracheoplasty with stenting with an Aboulker's tube or silastic sheets. The majority of the cases were acquired stenosis (64%) and the others congenital. The degree of stenosis was graded into four categories according to Cotton's classification. Thirty six cases were grade 2, 44 cases were grade 3, 21 cases were grade 4. Subglottic localization of the stenosis was found in 64% of the cases and the mobility of the vocal folds was normal in 60% of the cases. The surgery was considered successful after one procedure when there was a permanent and permeable laryngotracheal lumen (no more than grade 1) not requiring a tracheotomy. Of the 47 single-stage procedures, 38 were successful (81%); of the 54 cases managed with classic methods, 30 were successful (55%). These results and the indications of the different surgical procedures are discussed.

Transnasal endoscopic repair of congenital defects of the skull base in children.

OBJECTIVE: To examine imaging findings and methods of endoscopic treatment of congenital skull base defects in children. DESIGN: Retrospective study and case series. SETTING: Academic tertiary care center. PATIENTS: Four patients (aged 12 and 14 months and 8 and 13 years) were included from 1995 to 1997. Three presented with a nasal glioma, which was recurrent in 1 case. The fourth patient presented with bacterial meningitis due to a spontaneous cerebrospinal fluid leak. Computed tomography and magnetic resonance imaging were used to locate the defect of the skull base. INTERVENTION: Transnasal endoscopic resection of the glioma or the meningocele, with immediate repair of the skull base defects using free mucosal flaps and/or pediculized mucosal flaps and/or conchal cartilage together with fibrin glue and nasal packing during a 3-week period. RESULTS: None of the 4 patients has experienced recurrent cerebrospinal fluid leaks or postoperative meningitis. CONCLUSIONS: The transnasal endoscopic repair of congenital meningoceles is a reliable technique in select pediatric patients. Computed tomography and magnetic resonance imaging provide information that can be used to help the surgical procedure.

Vestibular function in children with the CHARGE association.

BACKGROUND: Histopathological examinations and computed tomographic scans of the temporal bone in patients with the CHARGE association (a malformative syndrome that includes coloboma, heart disease, choanal atresia, retarded development, genital hypoplasia, and ear anomalies, including hypoplasia of the external ear and hearing loss) have shown an absence of semicircular canals and a Mondini form of cochlear dysplasia. Until recently, no information was available concerning a possible loss of vestibular function, which could be a factor in retarded posturomotor development. To our knowledge, this is the first report of otolith tests done on patients with the CHARGE association. OBJECTIVE: To test residual vestibular function in patients with the CHARGE association. STUDY DESIGN: In 7 patients with the CHARGE association, we made electro-oculographic recordings of vestibulo-ocular responses to earth-vertical and off-vertical axis rotations to evaluate the function of the canal and the otolith-vestibular systems. RESULTS: None of the 7 patients had semicircular canals in the computed tomographic scan, and none had canal vestibulo-ocular responses to earth-vertical axis rotation, but all had normal otolith vestibulo-ocular responses to the off-vertical axis rotation test. CONCLUSIONS: These results support the hypothesis of a residual functional otolith organ in the hypoplastic posterior labyrinth of children with the CHARGE association. The severe delays in psychomotor development presented by these children are more likely a consequence of multiple factors: canal vestibular deficit, visual impairment, and environmental conditions (long hospital stays and breathing and feeding problems). The remaining sensitivity of the otolith system to gravity and linear acceleration forces in these children could be exploited in early education programs to improve their posturomotor development.

Facial neuromas in children: delayed or immediate surgery?

OBJECTIVE: The objective of this study was to investigate the clinical characteristics and outcome of facial nerve neuromas in children. To date, no specific study has focused on children, and the management of these tumors is not codified. DESIGN AND SETTINGS: A review of case series treated in a tertiary care center of pediatric otolaryngology. SUBJECTS: The treatment and outcomes for 7 children (4 infants and 3 adolescents) were analyzed. RESULTS: Six patients underwent complete removal of tumor and immediate restoration of the nerve continuity. The grade of facial palsy improved in 4 of the 6 children, but did not get better than grade 3 (House classification). The remaining patient was managed conservatively and remained stable clinically and radiologically after 9 years follow-up. CONCLUSIONS: These findings support the reasonable strategy of combining conservative assessment of these slow-growing tumors with regular clinical and radiologic evaluations and radical surgery using various procedures. The choice depends on the age of the child, the extent and growth rate of the tumor, the grade of facial palsy, and the hearing function.

The CHARGE association: the role of tracheotomy.

OBJECTIVES: To evaluate the need for a tracheotomy and its timing during the evolution of an association of malformations, including coloboma, heart defects, choanal atresia, developmental and growth retardation, genitourinary malformation, and ear anomalies (CHARGE association). DESIGN: Retrospective study from January 1988 through December 1997. SETTING: Four academic tertiary care centers. PATIENTS AND METHODS: Forty-five patients with CHARGE association having at least 3 cardinal malformations (growth retardation excluded) and review of the malformations and respiratory manifestations encountered. All the patients underwent endoscopic exploration on several occasions. We reviewed the nature and the timing of therapeutic interventions performed on the airway. RESULTS: Two patients died (one patient of septicemia, the other of unknown causes). Abnormalities of blood gas levels and/or sleep were found in 30 patients (67%), were responsible for cardiorespiratory arrest in 9 (20%), and required admission to the intensive care unit in 21 (47%). Pharyngolaryngeal anomalies leading to dyspnea (discoordinate pharyngolaryngomalacia, glossoptosis, retrognathia, laryngeal paralysis, cleft, stenosis, and difficult intubation) were found in 26 patients (58%). Tracheobronchial anomalies (esophagotracheal fistula, esophageal atresia, and tracheomalacia) were present in 18 patients (40%). Resection of the aryepiglottic folds was attempted 3 times, but without success. Tracheotomy was necessary in 13 patients (29%) at a median age of 2.4 months (mean duration, 25 months). Among these infants, the posterior nasal choanae were patent in 10 patients at the time of tracheotomy. Gastroesophageal reflux was encountered in 36 patients (80%). Prolonged enteral feeding was necessary in 21 patients (47%), with gastrostomy in 16 (of whom 9 needed a tracheotomy). These feeding difficulties and airway problems were highly correlated. CONCLUSIONS: We encountered multiple, complicated airway abnormalities. Resection of aryepiglottic folds was inadequate. Often, a tracheotomy could not be avoided in these patients, regardless of choanal patency. Tracheotomy needs to be performed early to avoid hypoxic events. In some selected patients, ventilation using bilevel positive airway pressure may be an alternative.

[Hearing status of Robin sequence patients]. / Audition et séquence de Robin.

OBJECTIVE: To determine wether Robin sequence is a risk factor for conductive and/or sensorineural hearing loss. PATIENTS: 13 children with type III Robin sequence, admitted in our institution between 1984 and 1997 for tracheotomy were enrolled in this retrospective study. METHODS: Each child had several audiological evaluations including subjective and objective methods adapted to their age. Subjective methods were audiometric tests, objective methods were Click Evoqued Otoacoustic Emissions and Auditory Brainstem Response. RESULTS: 3 children had normal hearing, 10 children had a conductive hearing loss caused by middle ear effusion, 4 patients had also a congenital permanent sensorineural evolutive hearing loss. Among the 4 infants with a sensorineural hearing loss, 2 had a polymalformative syndrome, and 2 had an isolated Robin sequence. CONCLUSION: Robin sequence is a risk factor for sensorineural hearing loss and conductive hearing loss. This hearing loss should be assessed as soon as possible after birth by otoscopy, click-evoqued otoacoustic emissions, auditory brainstem response and audiometric tests.

Nasal foreign bodies in children.

Between 1994 and 1997, a total of 72 nasal foreign bodies were removed from 68 children (28 girls and 40 boys, including 2 repeats) in the ENT Department at Robert Debré Hospital, Paris. Ages ranged from 1 to 12.5 years (median, 3 years). Two children had bilateral foreign bodies. The unilateral foreign bodies were on the right side in 67.6% of cases. The most frequent objects were plastic objects, beads, paper, cotton and foam. Insertion was witnessed by an adult or reported by the child himself in the majority of cases. The other cases were diagnosed when complications occurred (as seen by persistent rhinorrhea and a foul body odor). All foreign bodies were removed in the consultation room using a hook or nasal forceps.
