The DI appears to be a valid and reliable instrument to assess quality of life in exercise-induced pediatric PVFM. A DI change of 8 or higher seems significant. This instrument can serve as an objective tool to assess change in exercise-induced pediatric PVFM following speech therapy.

"Paradoxical" inspiratory and blunted expiratory vocal fold pattern responses to exercise best characterize EILO. Group differences were only seen with exercise challenge, thus highlighting the utility of provocation and control groups to identify EILO.

Poster Presentations P235 POSTERSMethod: We retrospectively reviewed charts of patients under 18 years who underwent parotidectomy between 1999 and 2011 at a tertiary pediatric center by a pediatric otolaryngologist. Distribution of dysfunction and timing of recovery were noted. Chi-square and t-test analyses were conducted to determine association between demographics or pathology and functional outcomes.Results: Forty-three patients met inclusion criteria. Forty-one underwent superficial parotidectomy, and 2 underwent total parotidectomy. Leading indications for surgery were atypical mycobacterium (16/4 [37.2%]) and branchial cleft anomaly (8/43 [18.6%]). The incidence of immediate facial nerve paralysis was 2% (1/43).The incidence of facial nerve paresis was 21% (9/43), distributed in the marginal mandibular nerve (n = 7), buccal branch (n = 1), and marginal mandibular nerve and frontal branch (n = 1). Full recovery of nerve function in patients with paresis occurred by 1 month (n = 2), 2 months (n = 1), 6 months (n = 3), or 10 months (n = 2). No association was revealed between age, gender, or pathology and postoperative facial nerve function. Conclusion:Transient postparotidectomy paresis of distal branches of the facial nerve is common in the pediatric population and should be discussed in the preoperative evaluation. The risk is comparable to that of the adult population. Although malignant disease would seem to portend greater risk of dysfunction, underlying pathology was not predictive. Pediatric Otolaryngology Quality of Life in Childhood HearingLoss: Systematic Review Tara Rachakonda, MD (presenter); Judith E. C. Lieu, MD; Marc C. Thorne, MD, MPH Objective: Though the functional performance of children with hearing loss (HL) has been assessed through audiometric and educational testing, quality of life (QOL) has not been as thoroughly addressed. This systematic review was undertaken to test the hypothesis that QOL in children with HL is worse than children with normal hearing.Method: MEDLINE, EBSCO, and EMBASE databases (end date 11/9/11) were searched for peer-reviewed articles that examined QOL of children 0 to 18 years with HL using validated QOL surveys. Abstracts were reviewed by 2 reviewers. Articles were excluded if children had fluctuating/temporary HL (such as otitis media) and/or cognitive impairment.Results: Of 963 articles initially located, 32 articles will be included for further evaluation using modified STROBE criteria: 2 case-control studies, 11 observational cohort studies, and 19 cross-sectional studies. Meta-analysis will be performed to combine data from the studies, and sensitivity analysis will be performed to evaluate the effect of methodologic quality on the overall results. Tests of heterogeneity will be performed and the literature collected will be examined for evidence of publication bias. Conclusion:We expect that though children with HL may experience worse QOL than their normal hearing peers, hearing assistive devices, such as conventional hearing aids, boneanchored hea...
