Pediatric Bilateral Vocal Cord Immobility: New Treatment With Preservation of Voice.

OBJECTIVES: Pediatric bilateral vocal cord immobility (BVCI) represents a severe life-threatening condition that often causes severe dyspnea. Endoscopic arytenoid lateral abduction (EALA) is a relatively new, secure, minimal-invasive surgical technique. The present prospective observational study aims to evaluate the effects of EALA in terms of respiratory function, voice quality, and swallowing capabilities. METHODS: Twenty-one pediatric patients with BVCI underwent EALA. Eleven out of 21 patients had tracheostomy at the time of surgery. Pre and postoperative functional assessments included endoscopic evaluation, maximum phonation time, pediatric Voice Handicap Index (pVHI), GIRBAS Scale criteria, and Montreal Children's Hospital Feeding scale (MCH-Feeding scale). peak tidal inspiratory flow or peak inspiratory flow (PIF) and number of desaturations/hour (ODI/h) were evaluated in patients without tracheostomy. RESULTS: Postoperative endoscopy showed glottic airway improvement in all patients. Average time for decannulation was 4.6 weeks. One patient has not yet been decannulated. No major complications occurred. In patients without tracheostomy, we observed a significant improvement of ODI/h and PIF after surgery (p < 0.05) as expected. PVHI, MCH-Feeding scale, and GIRBAS score significantly worsened 1 month after surgical intervention (p < 0.05). One year after surgery, however, all values, except for B and A parameters of the GIRBAS score, returned to levels comparable to those preoperative. CONCLUSIONS: EALA represents a simple, safe and effective solution in pediatric patients with BVCI, avoiding tracheostomy, allowing early decannulation, preserving swallowing function, and maintaining good quality voice.

Prelingual auditory-perceptual skills as indicators of initial oral language development in deaf children with cochlear implants.

OBJECTIVES: To assess when prelingually deaf children with a cochlear implant (CI) achieve the First Milestone of Oral Language, to study the progression of their prelingual auditory skills in the first year after CI and to investigate a possible correlation between such skills and the timing of initial oral language development. METHODS: The sample included 44 prelingually deaf children (23 M and 21 F) from the same tertiary care institution, who received unilateral or bilateral cochlear implants. Achievement of the First Milestone of Oral Language (FMOL) was defined as speech comprehension of at least 50 words and speech production of a minimum of 10 words, as established by administration of a validated Italian test for the assessment of initial language competence in infants. Prelingual auditory-perceptual skills were assessed over time by means of a test battery consisting of: the Infant Toddler Meaningful Integration Scale (IT-MAIS); the Infant Listening Progress Profile (ILiP) and the Categories of Auditory Performance (CAP). RESULTS: On average, the 44 children received their CI at 24±9 months and experienced FMOL after 8±4 months of continuous CI use. The IT-MAIS, ILiP and CAP scores increased significantly over time, the greatest improvement occurring between baseline and six months of CI use. On multivariate regression analysis, age at diagnosis and age at CI did not appear to bear correlation with FMOL timing; instead, the only variables contributing to its variance were IT-MAIS and ILiP scores after six months of CI use, accounting for 43% and 55%, respectively. CONCLUSION: Prelingual auditory skills of implanted children assessed via a test battery six months after CI treatment, can act as indicators of the timing of initial oral language development. Accordingly, the period from CI switch-on to six months can be considered as a window of opportunity for appropriate intervention in children failing to show the expected progression of their auditory skills and who would have higher risk of delayed oral language development.
