RESUMEN
IMPORTANCE: Non-steroidal anti-inflammatory drugs (NSAIDs) are known to inhibit chemotaxis, oxidative burst and phagocytosis, bacterial killing in granulocytes as well as inhibiting neutrophil aggregation or degranulation, thereby interfering with the function of lymphocytes. On the other hand, ibuprofen is widely prescribed in pediatrics for its powerful analgesic and antipyretic effects. To our knowledge, no previous publication outlines the relationship between Ibuprofen therapy and an increased risk of intracranial and/or orbital complications of acute fronto-ethmoidal sinusitis in childhood. OBJECTIVE: To look for a relationship between ibuprofen and occurrence of intra-cranial and/or orbital complications of acute fronto-ethmoidal sinusitis in pediatrics. SETTING AND METHODS: The medical charts of patients younger than 18 years admitted into the E.N.T. departments of 4 academic care centers during 2 consecutive years for fronto ethmoidal sinusitis were reviewed retrospectively. The history of ibuprofen intake, the occurrence of complication (orbital or intracranial) as well as the usual demographic data were noted. A statistical analysis was performed in order to ascertain whether a relationship between taking NSAIDs and the onset of an intracranial and/or orbital complication exists. RESULTS: Intake of ibuprofen appeared to be a risk-factor of intracranial complications or associated orbital and intracranial complications of acute fronto-ethmoidal sinusitis in children. Neither gender nor age nor initial pain intensity were statistically related to the onset of complications. CONCLUSION AND RELEVANCE: This retrospective multicenter cohort study appears to suggest that ibuprofen increases the risk of orbital and/or intracranial complications of acute fronto-ethmoidal sinusitis in childhood. Therefore, we recommend not prescribing ibuprofen if one suspects an acute sinusitis in a child or adolescent.

OBJECTIVE: The study objective was to determine risk factors for severity of juvenile-onset recurrent respiratory papillomatosis (RRP) at first endoscopic evaluation. METHODS: Based on a review of all cases undergoing surgery for juvenile-onset RRP in two pediatric otolaryngology departments in the USA and France, the following severity risk factors were analyzed: number of laryngeal levels involved, extension to the subglottis, and bilateral involvement. RESULTS: Thirty-two patients were included, with 571 endoscopic procedures. Number of endoscopies per patient varied according to initial extension: 30.67 procedures when all three levels were involved, 15.57 procedures when two and 14.08 procedures when only one (P=0.03). The odds ratio for risk of >14 procedures in 3-level involvement was 20.43 (P=0.047). Initial subglottic extension tended to be associated with more endoscopic procedures (23.67 vs 15.56, P=0.16). CONCLUSIONS: RRP severity correlated with initial laryngeal extension of papillomatous lesions at first endoscopy. This finding allowed a short 3-item assessment scale to be created for routine use, complementary to Derkay's assessment scale.

OBJECTIVES: Nasal obstruction is a highly subjective symptom. It can be evaluated by combining clinical examination, imaging and functional measurements such as active anterior rhinomanometry (AAR). In pediatrics, AAR is often impossible because it requires the participation of the child. Airflow modeling by Computational Fluid Dynamics (CFD) has been developed since the early 1990s, mostly in adults. This study is the first to describe a methodology of "numerical rhinomanometry" in children using CFD and to evaluate the feasibility and the clinical interest of this new tool. MATERIALS AND METHODS: Five children aged from 8 to 15 years, complaining of nasal obstruction, underwent routine management including clinical evaluation, AAR, and CT-scanning. CT acquisitions were used for CFD calculations and numerical rhinomanometry. RESULTS AND CONCLUSIONS: In the 5 children, the results of CFD were concordant with clinical complaints and examination. In 3 children, AAR and CFD were concordant. In one patient, CFD corrected the results of AAR. In one patient, AAR was not feasible, unlike CFD, which contributed to diagnosis. This study highlighted the feasibility of CFD in children and that it can support or refute diagnosis of nasal obstruction with good reliability. These results indicate that CFD modeling could be widely used for functional exploration in pediatric rhinology.

OBJECTIVE: voice disorders are common in the pediatric population and can negatively affect children's quality of life. The pediatric voice handicap Index (pVHI) is a valid instrument to assess parental perception of their children voice but it is not translated into French language. The aim of the present study was to adapt a French version of the pVHI and to evaluate its psychometric properties including construct validity, reliability, and some aspects of external validity. PATIENTS AND METHOD: we performed a cross sectional study including 32 dysphonic children and 60 children with no history of voice problems between 3 and 12 years of age. The original pVHI was translated into French language according to forward-backward rules and then administered to parents or caregivers. Construct validity and internal consistency were explored using confirmatory factor analysis and Cronbach's alpha. The questionnaire was filled twice to assess test-retest reliability using the intra-class correlation coefficient. The external validity was explored by comparing the French pVHI total and subscales scores between dysphonic and asymptomatic children. Correlations between the French pVHI and both the perceptual GRBAS scale and the health-related quality of life (HRQOL) survey "Vécu et Santé Perçu de l'Adolescent et de l'Enfant" (VSP-Ap) were also performed. RESULTS: the structure of the French pVHI showed a good fit with excellent reliability (α = 0.929) and high test-retest reliability. Significant differences were found between the group of dysphonic children and the control group (p < 0.001). The French pVHI scores were positively correlated to all parameters of the GRBAS scale (p < 0.05). Significant negative correlations were found between the Functional domain of the pVHI and various domains of the VSP-Ap as Leisure Activities, Schooling and Sentimental Relationship (p < 0.05). CONCLUSION: the French pVHI is considered to be a valid and reliable instrument to assess voice-related quality of life in children with voice disorder. We recommend its use in the multidimensional protocols for assessing voice disorder in the pediatric population.

OBJECTIVE: This study presents results for a pediatric series of tympanoplasty using the butterfly-cartilage technique, with comparison to literature reports. METHODS: A retrospective study included patients aged between 2 and 12 years receiving tympanoplasty performed by a single senior surgeon in our department between 2003 and 2012, for whom pre- and postoperative tympanum imaging was complete. Results were analyzed at a minimum 10 months' follow-up in terms of graft healing and auditory data, with pre- and postoperative audiograms and calculation of mean hearing loss. RESULTS: Twenty-eight tympanoplasties were performed in 27 children: 16 males, 11 females; in 1 case, perforation was bilateral. Perforation location was inferior or antero-inferior in 14 cases (50%), antero-superior in 9 (32.1%) and anterior in 5 (17.9%). Perforation size on otoscopy ranged from 11.1% to 36.4% of tympanum area (mean, 26.3%). Mean follow-up was 25 months. Closure of the perforation was achieved in 87.7% of cases. Mean hearing loss was 20.2dB (range, 10-31.25dB) preoperatively and 14dB (range, 5-31.25dB) postoperatively. DISCUSSION: We analyze our results and compare them with the international literature to refine indications for this technique of tympanic repair. CONCLUSION: Tympanoplasty using the butterfly-cartilage technique was reliable and easy to perform. It should be included in the therapeutic armamentarium for moderate non-marginal tympanic perforation. In the present series, the technique was reserved to perforations involving less than 40% of tympanum area.

INTRODUCTION: Congenital nasal pyriform aperture stenosis (CNPAS) is a rare disease presenting with neonatal respiratory distress, often associated with other anomalies. MATERIALS AND METHODS: This study reports the clinical and radiological characteristics of the patients managed in The Department of Pediatric Otolaryngology Head and Neck Surgery of La Timone Children's Hospital in Marseille between 1988 and 2014. Pyriform aperture (PA) widths were measured on CT-scans, obtained by using hand calipers at the largest portion of the PA in a plan parallel to the Francfort plan. RESULTS: 10 patients were included. Average PA width was 6.6mm, 5/10 patients presented with single central maxillary median incisor, 6/10 patients had associated abnormalities. 8 patients underwent a surgical intervention and 2 patients were medically managed. All the patients had satisfactory nasal airway permeability on late follow-up. A management algorithm was elaborated. CNPAS should be evoked when breathing difficulties are associated with impossibility of passing fiberscope or nasogastric tube at the nasal inlet. Craniofacial CT-scanning is necessary to make the diagnosis and look for associated abnormalities. Medical treatment associating nasal wash and decongestants should be performed. Surgical intervention is necessary when failure of the medical management. DISCUSSION AND CONCLUSIONS: Our results were close to those found in the literature in terms of clinical characteristics, associated abnormalities and PA width. However, no objective criterion to decide whether a surgical intervention is necessary or not, has been established so far. The algorithm we propose offers guidelines from diagnosis to treatment, but the management should be adapted based on clinical tolerance.

OBJECTIVES: The aim of this study was to assess quality of life in children fitted with cochlear implants, using combined self- and parental assessment. MATERIALS AND METHODS: Thirty-two children, aged 6 to 17 years, with prelingual hearing loss and receiving cochlear implants at a mean age of 22 months, were included along with their families. The KIDSCREEN-27 questionnaire was implemented, in face-to-face interview, in its parents and children-adolescents versions, with 27 items covering physical well-being ("physical activities and health"), psychological well-being ("general mood and feelings about yourself"), autonomy & parents ("family and free time"), peers & social support ("friends") and school environment ("school and learning"). Parent and child responses were compared with a general population database, and pairwise. RESULTS: Global scores were compared against the general population on Cohen d effect-size. For child self-assessment, the results were: physical well-being, 72.81 (d=0); psychological well-being, 78.13 (d=-0.4); autonomy & parents, 63.84 (d=-0.2); peers & social support, 61.72 (d=-0.4); and school environment 73.83 (d=0). For parent assessment, the respective results were 62.66 (d=-0.8), 74.89 (d=-0.3), 57.37 (d=-1.2), 51.56 (d=-0.8), and 68.95 (d=-0.4). Half of the children could not answer the questionnaire, mainly due to associated disability. Schooling and language performance were poorer in non-respondent than respondent children. Quality of life was comparable between implanted and non-implanted children: Cohen d, 0 to 0.4. Early cochlear implantation in children with pre-lingual hearting loss provides quality of life comparable to that of the general population.

The main objective was to evaluate the bimodal self-rated benefits on auditory performance under real conditions and the quality of life in two groups of cochlear-implanted adults, with or without a contralateral hearing aid. The secondary objective was to investigate correlations between the use of a hearing aid and residual hearing on the non-implanted ear. This retrospective study was realized between 2000 and 2010 in two referral centers. A population of 183 postlingually deaf adults, implanted with a cochlear experience superior to 6 months, was selected. The Speech, Spatial, and other Qualities of Hearing Scale were administered to evaluate the auditory performances, and the Nijmegen Cochlear Implant Questionnaire to evaluate the quality of life. The population was divided into two groups: a group with unilateral cochlear implants (Cochlear Implant-alone, n = 54), and a bimodal group with a cochlear implant and a contralateral hearing aid (n = 62). Both groups were similar in terms of auditory deprivation duration, duration of cochlear implant use, and pure-tone average on the implanted ear. There was a significant difference in terms of pure-tone average on low and low-to-mid frequencies on the non-implanted ear. The scores on both questionnaires showed an improvement in the basic sound perception and quality of social activities for the bimodal group. The results suggest that the bimodal stimulation (cochlear implant and contralateral hearing aid) improved auditory perception in quiet and the quality of life domain of social activities.

OBJECTIVES: The purpose of this study was to assess the postoperative complications related to cochlear implants and to discuss the differences observed between adult and paediatric populations. Cochlear implant complications were defined as any pathological events observed during the postoperative period, whether or not they were directly related to the surgical technique. We therefore recorded all complications, in the broad sense of the term, ranging from acute otitis media to cochlear explantation. STUDY DESIGN: Retrospective analysis of cochlear implant patients. MATERIAL AND METHODS: All surgical procedures (unilateral or bilateral cochlear implantation, revision surgery) performed in our institution between March 1993 and January 2013 were reviewed. This population comprised 168 adults (median age at the time of implantation: 51.9 years), and 235 children (median age at the time of implantation: 4.5 years). All postoperative complications were classified as either major (requiring surgical revision or hospital management) or minor (requiring conservative management). RESULTS: The global complication rate was 19.9% (80/403 cases), comprising 5% of major complications (20 cases) and 14.9% of minor complications (60 cases). This complication rate was significantly higher in the adult population (P=0.004). CONCLUSION: Cochlear implantation is a safe hearing rehabilitation surgical technique associated with a low complication rate. However, surgeons must be familiar with these complications in order to ensure optimal prevention. Minor complications were mainly infectious in children (acute otitis media) and cochleovestibular in adults (tinnitus and vertigo). Major complications were mostly reimplantation following revision surgery or device failure. Only the minor complication rate was significantly higher in the adult population.

INTRODUCTION: Ossifying fibroma (OF) is a rare benign fibro-osseous tumor, mainly located in the head and neck region. Most often, it affects the mandible but rare involvement of paranasal sinuses has been reported, associated with more locally aggressive behavior. CASE REPORT: We report the case of an 8-year-old boy with OF of the middle turbinate, revealed by ethmoiditis. Total resection was performed on an endoscopic approach. The patient was free of clinical or radiological recurrence at 3 years' follow-up. This was the youngest patient with OF of the middle turbinate so far reported in the international literature. DISCUSSION: Presumptive diagnosis is established by clinical examination and CT scan (location, oval-shaped mass, heterogeneous tumor with a thin bony rim). Definitive diagnosis is founded on histological examination (psammomatous bodies, osteoblastic rim, trabecular bone). Treatment in paranasal sinus OF is surgical, preferentially on an endoscopic approach. Resection should be as complete as possible to minimize risk of recurrence, especially in sinonasal locations, known to be more aggressive. Ethmoiditis in an unusual age-range should suggest tumoral etiology.

A 7-month-old girl presented with left acute mastoiditis and a white blood cell count of 79,000/mm(3). A surgically obtained bacteriological sample showed Streptococcus pneumoniae. Direct blood examination revealed leukemic blast cells. Histological samples showed leukemic infiltration of the left temporal bone. The final diagnosis was Burkitt's leukemia with left temporal bone leukemic infiltration. The patient received chemotherapy according to the LMB 2001 protocol from the Société française d'oncologie pédiatrique. Clinical, biological, and imaging follow-up 30 months after the end of treatment showed remission with complete recovery in the left temporal bone. Atypical presentation of acute mastoiditis (AM) should prompt investigation into whether there is a rare underlying pathology, such as a hemopathy, histiocytosis, or solid tumor. The first sign of leukemia may be acute middle ear disease. To our knowledge, no other cases of Burkitt's leukemia with temporal bone leukemic infiltration presenting as AM have been reported in a child under 1 year of age.

UNLABELLED: Sensorineural hearing loss is the most common form of sensory impairment in children. As a precise aetiological diagnosis has major prognostic and management implications, it is useful to evaluate the contents of the aetiological investigation of sensorineural hearing loss in France. This article presents a retrospective review of professional practices by comparing the aetiological investigation of hearing loss in children with a cochlear implant and children without a cochlear implant. PATIENTS AND METHODS: One hundred and seven children under the age of 18 years with unilateral or bilateral sensorineural hearing loss attending the paediatric ENT department for the first time between January 2007 and January 2009 were included in the study. Data from the clinical interview and all complementary investigations were analysed. RESULTS: The various aetiologies of hearing loss were classified as genetic, acquired, or unknown in each of the two populations. Hearing loss was of unknown origin in 52% of the 87 non-implanted children and 15% of the 20 children with a cochlear implant. CONCLUSION: This study demonstrates the heterogeneous practices in terms of aetiological investigation of sensorineural hearing loss as a function of the target population. A more systematic aetiological investigation was performed in children fitted with a cochlear implant, requiring multidisciplinary management. This study indicates the need to define a standard aetiological investigation for all children with sensorineural hearing loss.

Mutations of the COCH gene inherited in an autosomal dominant mode are responsible for late-onset cochleovestibular impairment on both sides. Our objective is to report the youngest patient (3 years) associating a molecular variant of the COCH gene and a cochleovestibular impairment on both sides. The clinical sequence has started with a vestibular dysfunction in a two-year-old child: recurrent rotatory dizziness during 12 months. At the age of 3, a sensorineural hearing loss on both sides has occured associated with spontaneous variation during 6 months. The lack of mutation of the connexin 26, connexin 30 and pendrin genes has reorientated the genetic investigation. A molecular variant of the COCH gene was found in the vWFA2 domain. It was an in-frame deletion predicting the synthesis of an abnormal protein in which 21 aminoacid were missing. Others family members with mutation were asymptomatics. In this isolated case report, the study was in favor of a non pathogenic molecular variant of the COCH gene. For all that, mutations of the COCH gene could be searched in progressive cochleovestibular dysfunctions on both sides in children, even without family affect.

After more than 20 years of clinical experience in children, bone-anchored hearing aids, essentially BAHA(®), have become the standard treatment for conductive or mixed hearing loss. Based on a general review of the literature and the authors' own experience, this article reviews the use of bone-anchored hearing aids in children. The main indications for bone-anchored hearing aids are a minimum age of 5 years at the time of implantation and/or cortical bone thickness ≥ 3 mm. Fixture loss is observed in 40% of children under the age of 5 years versus 8% for children aged 5 to 10 years and 1% for children over the age of 10 years, i.e. identical to the rate observed in adults. Skin complications are similar to those observed in adults and must be prevented by parental education and regular follow-up. Surgery is generally performed in two stages or as a one-stage procedure for fixtures ≥ 4 mm. The functional success rate, correlated with medium- and long-term use of BAHA(®) is about 96%. BAHA(®) may be indicated in children with profound unilateral hearing loss following a trial period wearing a BAHA(®) headband for several weeks with the child's active participation. Sequential bilateral implantation requires complementary investigations and appears to provide improved perception in noise. This type of hearing aid provides an improvement of the quality of life of children with bilateral conductive and/or mixed hearing loss which should be further improved as a result of recent technical developments.

OBJECTIVE: The aim was to report the results of the first case in France of pediatric auditory rehabilitation with a middle ear implant and to discuss the putative indications with this new therapeutic option in children. PATIENT AND METHODS: A prospective study over 18 months on clinical and audiometric results after a middle ear implantation with a Vibrant Med-El(R) implant in a 9-year-old child with mixed hearing loss. RESULTS: Postoperative unaided pure tone audiometry (PTA) was unchanged by the surgical procedure. After 18 months of implant use, the mean PTA loss in free-field warble tone audiometry was 33.75 dB and the intelligibility threshold was 30 dB. After 18 months of follow-up, the intelligibility threshold was improved by 25 dB in comparison with the preoperative results with two hearing aids. The implant worked perfectly well and the child did not show any complication during this period. CONCLUSION: The reliability of the implant and the quality of the auditory results obtained in this case and in a limited number of cases in the world make the Vibrant Med-El(R) a new therapeutic option in hearing loss in children with bilateral auricular atresia.

OBJECTIVE: To appreciate the several head and neck manifestations of Langherans' cell histiocytosis (LCH) in children and their multidisciplinary management and outcome. STUDY DESIGN: Retrospective study. PATIENTS AND METHODS: Clinical reports of 42 patients with LCH treated in the Departments of Paediatric Haematology, Paediatric Oncology and Paediatric Otorhinolaryngology of a tertiary care center were analyzed. Only cases where the disease was localized to the head and neck were considered. The age at diagnosis, gender, clinical presentation, extension of disease as well as response to treatment and outcome were recorded from the charts of each of these patients. RESULTS: Of the 42 patient charts reviewed, 31 (73.8%) presented with head and neck localization. 10 of these had an exclusive head and neck presentation. Multisystem LCH was mostly found in infants under 3-year-old (mean age: 2-year-old), and bony manifestations in older. All treatments delivered to patients were well-tolerated and the evolution good. DISCUSSION AND CONCLUSION: Head and neck involvement is known to be very frequent in LCH. There is no consensus about treatment but authors highlight that all teams in charge of patients presenting with LCH agree to remain as conservative as possible. For solitary large lesions looking like a tumor which resection could result in functional or cosmetic morbidity, it would be important to get first a biopsy. For multisystemic LHC, therapeutic trials with chemotherapy agents still in process should increase the rate of success.

BACKGROUND: Many authors have studied adult's larynx modelization, but the mechanisms of newborn's voice production have very rarely been investigated. After validating a numerical model with acoustic data, studies were performed on larynges of human fetuses in order to validate this model with aerodynamical experiments. MATERIAL AND METHODS: Anatomical measurements were performed and a simplified numerical model was built using Fluent((R)) with the vocal folds in phonatory position. The results obtained are in good agreement with those obtained by laser Doppler velocimetry (LDV) and high-frame rate particle image velocimetry (HFR-PIV), on an experimental bench with excised human fetus larynges. RESULTS: It appears that computing with first cry physiological parameters leads to a model which is close to those obtained in experiments with real organs.

Anterior laryngeal webs can be congenital or acquired and occur secondary to a surgical procedure, intubation, or infection. Clinical presentation can include vocal and respiratory symptoms. The first step in managing a laryngeal web is performing flexible laryngoscopy, followed by a direct laryngoscopy under general anesthesia. Treatment remains a challenge. Endoscopically, the web can be incised with cold instruments or by laser, mitomycin-C can be applied, and a silastic keel can be inserted in the anterior commissure. Externally, an anterior cricothyrotomy is necessary and a silastic keel can be placed; anterior cartilage graft can be inserted in case of a thick web. Regardless of the technique used, the primary concern is recurrence.
