RESUMEN
Introduction Atresia of the external auditory canal affects 1 in every 10 thousand to 20 thousand live births, with a much higher prevalence in Latin America, at 5 to 21 out of every 10 thousand newborns. The treatment involves esthetic and functional aspects. Regarding the functional treatment, there are surgical and nonsurgical alternatives like spectacle frames and rigid and softband systems. Active transcutaneous bone conduction implants (BCIs) achieve good sound transmission and directly stimulate the bone. Objective To assess the audiological performance and subjective satisfaction of children implanted with an active transcutaneous BCI for more than one year and to compare the outcomes with a nonsurgical adhesive bone conduction device (aBCD) in the same users. Methods The present is a prospective, multicentric study. The audiological performance was evaluated at 1, 6, and 12 months postactivation, and after a 1-month trial with the nonsurgical device. Results Ten patients completed all tests. The 4-frequency pure-tone average (4PTA) in the unaided condition was of 65 dB HL, which improved significantly to 20 dB HL after using the BCI for 12 months. The speech recognition in quiet in the unaided condition was of 33% on average, which improved significantly, to 99% with the BCI, and to 91% with the aBCD. Conclusion The aBCD demonstrated sufficient hearing improvement and subjective satisfaction; thus, it is a good solution for hearing rehabilitation if surgery is not desired or not possible. If surgery is an option, the BCI is the superior device in terms of hearing outcomes, particularly background noise and subjective satisfaction.

RESUMEN
Objetive: To linguistically adapt and validate the Spanish version of the PEACH rating scale and identify the variables associated.Design: A transversal study of parents/guardians of infants and children with either normal hearing or hearing impairment.Study sample: The protocol included translation into Spanish and adapted linguistically. Regression models were constructed using logistic regression, obtaining the respective areas under the ROC curve. Validity was studied through an exploratory factor analyses and reliability analysis was carried out using Cronbach's Alpha.Results: The PEACH rating scale was carried out on 297 parents. There was a high degree of reliability for both children with hearing impairment (Cronbach's Alpha: 0.93) and for those with normal hearing (Cronbach's Alpha: 0.82). The exploratory factor analysis showed the existence of one factor (unidimensional). In relation to the variables associated with the global scores of the scale, the type of hearing loss and laterality impact on the score. The area under the ROC curve was 0.89, showing elevated sensitivity and specificity.Conclusions: The adapted version can be used to evaluate the effectiveness of amplification for infants and children with hearing impairment in Spanish-speaking children. The PEACH rating scale to Spanish has validity indicators similar to the original.

The most frequent palate diagnoses in patients with chromosome 22q11.2 deletion syndrome are a classic submucous cleft, occult, and velopharyngeal insufficiency without cleft, which generates alterations in speech that require surgery. Surgical protocols are controversial owing to syndrome characteristics that make their handling more complex. Pharyngeal flap pharyngoplasty is effective for this type of patient. The objective of this study is to examine the surgical management of velopharyngeal insufficiency in patients with chromosome 22 deletion, using a pharyngeal flap as the primary surgery. The clinical records of patients with chromosome 22 deletion and velopharyngeal insufficiency between 2015 and 2017 were analyzed retrospectively. Eight patients underwent pharyngeal flap pharyngoplasty as a primary surgery, including 1 with velopharyngeal insufficiency without a cleft, 1 with a classic submucous cleft, and 6 with occult submucous cleft. The pre- and postoperative protocol performed by speech therapists and surgeons included clinical evaluation of the oral cavity; perceptual, video recording, and nasometry speech evaluation; and videonasopharyngoscopy. All perceptual parameters and nasometry results significantly changed. Of the cases, 88% achieved a flap with the expected width and height and complete closure of the velopharyngeal sphincter. One patient required flap revision. Four of the 8 patients achieved normal resonance, and 2 of 8 showed mild hypernasality. Using the pharyngeal flap pharyngoplasty as a primary technique to correct velopharyngeal insufficiency in patients with chromosome 22 deletion provides satisfactory outcomes and decreases the number of surgeries. Preoperative planning must be conducted carefully and needs to be individualized to be successful.

AIM: The aim of this study is to present the middle fossa technique (MFT) as an alternative for patients who cannot undergo traditional surgery for active transcutaneous bone conduction implants (ATBCI) due to their altered anatomy or desire for future aesthetic reconstruction. DESIGN: A case series descriptive study was designed. The MFT was developed. Preoperative and postoperative information from 24 patients with external auditory canal atresia (EACA) and implanted with ATBCI was reviewed. RESULTS: A total of 24 children with bilateral EACA received implants in the middle cranial fossa. Their average age was 12. Of these patients, eight had an associated congenital disorder: Goldenhar Syndrome, Treacher Collins Syndrome or the Pierre Robin Sequence. The average follow-up was at 17 months (ranging from between 2- and 36 mo) and there were no major complications. Four patients showed skin erythema at the processor site after turn on, which was solved by lowering the magnet strength. One patient had a scalp hematoma that required puncture drainage. The hearing thresholds went down on average from 66.5 to 25.2âdB 1 month after turn on. Speech recognition improved respectively from 29.4% without and 78.9% with a bone conduction hearing aid to 96.4%. CONCLUSION: MFT placement of the ATBCI was proven to be safe and effective and a viable option for treating pediatric patients with EACA who cannot receive implants at the sinodural angle or in the retrosigmoidal position because of their altered anatomy and/or desire for future aesthetic reconstruction.

OBJECTIVE: To describe, in terms of functional gain and word recognition, the audiological results of patients under 18 years of age implanted with the active bone conduction implant, Bonebridge™. DESIGN: Retrospective case studies conducted by reviewing the medical records of patients receiving implants between 2014 and 2016 in the public health sector in Chile. STUDY SAMPLE: All patients implanted with the Bonebridge were included (N = 15). Individuals who had bilateral conductive hearing loss, secondary to external ear malformations, were considered as candidates. RESULTS: The average hearing threshold one month after switch on was 25.2 dB (95%CI 23.5-26.9). Hearing thresholds between 0.5 and 4 kHz were better when compared with bone conduction hearing aids. Best performance was observed at 4 kHz, where improvements to hearing were observed throughout the adaptation process. There was evidence of a significant increase in the recognition of monosyllables. CONCLUSIONS: The Bonebridge implant showed improvements to hearing thresholds and word recognition in paediatric patients with congenital conductive hearing loss.
