OBJECTIVES/HYPOTHESIS: To analyze existing evidence regarding utility of laryngeal electromyography (LEMG) for prognosis in cases of vocal fold palsy (VFP). STUDY DESIGN: Meta-analysis of studies reporting LEMG results and clinical outcomes in 503 patients with of VFP identified by literature search. METHODS: Studies were identified by literature search. Method of diagnosis, interval to LEMG, criteria for prognostication, and outcome were assessed. Criteria for prognosis were standardized to the extent possible across all studies, and studies were checked for consistency in outcome measures and assessments. Pooled data were subjected to statistical analysis. RESULTS: A total of 296/503 patients (58.8%) had findings predictive with poor prognosis, whereas 207/503 (41.2%) had findings of recovery. According to laryngoscopic examination, 269/296 patients with predicted poor recovery had poor recovery (positive predictive value = 90.9%), whereas 27/296 (9.1%) had good recovery. In patients with findings consistent with recovery, 115/207 (negative predictive value = 55.6%) noted return of motion, whereas 88/207 (44.4%) did not. The odds ratio was 11.56 with 95% confidence interval of 7.10-18.81. CONCLUSIONS: LEMG is a good predictor of poor recovery in patients with VFP and is clinically useful in identifying candidates for early definitive intervention

PURPOSE: Spasmodic dysphonia (SD) is an idiopathic voice disorder that is characterized by either a strained, strangled voice quality or a breathy voice with aphonic segments of connected speech. It has been suggested that environmental factors play a role in triggering the onset. Clinical observation suggests that some patients associate onset with specific events or factors while others do not. The purpose of this study was to examine a large database of SD patients to determine if specific triggers are associated with the onset of SD. PROCEDURES: Retrospective chart review. RESULTS: A total of 350 charts of patients with SD were identified and were categorized as either 'sudden onset' or 'gradual onset.' One hundred sixty-nine recalled their circumstances surrounding onset. Forty-five percent of these patients described the onset as sudden. Patient perceptions of inciting events in the sudden onset group were identified 77% of the time and 2% of the time in the gradual onset group. The most common factors identified were stress (42%), upper respiratory infection (33%), and pregnancy and parturition (10%). CONCLUSIONS: Thirty-five percent of SD patients perceive their disorder to have a sudden onset with identified inciting events. This prevalence raises questions regarding possible behavioral and environmental factors surrounding the onset of this disorder

OBJECTIVES: To observe the extent of nasal polyposis endoscopically in a cystic fibrosis population before the first surgical intervention and to grade the extent using a modified Malm scale, to observe patients prospectively and record the need for revision endoscopic sinus surgery (ESS), and to compare this among the individual polyp grading groupings. DESIGN: Retrospective medical record review of data collected prospectively. SETTING: Tertiary care hospital. PATIENTS: Forty-nine consecutive patients with a clinical preoperative diagnosis of cystic fibrosis and sinusitis. MAIN OUTCOME MEASURES: Using a modified Malm scale, the extent of polyps was prospectively graded into 3 groups before the first surgical intervention. The number of patients needing revision ESS and the mean time to revision ESS were compared among the 3 groups. RESULTS: Forty-nine consecutive patients underwent ESS between 1992 and 2007. We used a 3-stage system for extent of polyposis: 16 patients were noted to have no polyps (grade A), 14 had mild polyposis (grade B), and 19 had extensive polyposis (grade C). During the study, 14 patients required revision surgery: 3 with mild polyps and 11 with extensive polyps. Mean time to revision surgery was 39.7 months for those with grade B and 23.8 months for those with grade C. In the overall statistical analysis, the rate of revision ESS was significantly different among the 3 groups (P < .001). In pairwise comparisons, there were significant differences between those with grades A and C (P < .001) and between those with grades B and C (P = .04) and a trend toward significance between those with grades A and B (P = .052). There were no complications from ESS. CONCLUSION: Preoperative grading of nasal polyposis in patients with cystic fibrosis can help assess the future likelihood of revision ESS

OBJECTIVE: To determine whether a 3-day course of postoperative antibiotics is as effective as a 7-day course in reducing pain and reducing time to resumption of a normal diet and level of activity following pediatric tonsillectomy. DESIGN: A prospective, randomized, placebo-controlled trial. SETTING: Academic medical center. PATIENTS: Forty-nine patients were enrolled in the study. Preoperative demographic information was obtained. INTERVENTIONS: Tonsillectomy with or without adenoidectomy was performed by the senior author (J.J.) using electrocautery. Patients were randomized to receive either a 3- or 7-day course of amoxicillin. MAIN OUTCOME MEASURES: Parents were asked to record the following information: analgesic use for the first 7 postoperative days, postoperative days the child initiated his or her usual diet and level of activity, and medical treatment for oral hemorrhage or dehydration. RESULTS: Of the 49 patients, 26 were randomized to receive 7 days of postoperative antibiotics (group A) and 23 to receive 3 days of antibiotics, followed by 4 days of placebo (group B). Results were obtained for 47 of the enrolled patients (96%). No statistically significant difference was noted between the 2 groups with regard to postoperative pain or time to resumption of a normal diet and level of activity. CONCLUSION: A 3-day course of antibiotics following pediatric tonsillectomy is as effective as a 7-day course with regard to postoperative analgesic use and resumption of normal diet and level of activity.

INTRODUCTION: Tracheotomy for long-term ventilation is a common surgical procedure in the hospital setting. Although the postoperative care is often perceived as routine, complications associated with tracheostomy changes may result in loss of airway and death. In addition, the practice patterns, rationale, and complications related to tube changes have been poorly described. STUDY DESIGN AND METHODS: A survey of chief residents in accredited otolaryngology training programs was performed to determine the management strategies, rationale, and complications associated with postoperative tracheostomy tube changes. RESULTS: The first tube change was performed after a mean of 5.3 (range, 3-7) days after the procedure, most frequently by junior residents. The first change was performed in a variety of locations including the intensive care unit (88%), step down unit (80%), and regular floor (78%). Twenty-five percent performed these changes at night or on weekends. The most frequently reported rationale for performing routine tracheotomy changes was examination of the stoma for maturity (46%), prevention of stomal infection (46%), and confirmation of stability for transport to a less monitored setting (41%). Twenty-five (42%) respondents reported awareness of a loss of airway, and nine (15%) respondents reported awareness of a death as a result of the first tube change at their institution during their residency. A statistically significant higher incidence of airway loss was reported by respondents who reported performing the first tube change on the floor (96.1% vs. 63.6%). CONCLUSION: There is significant variability in the approach to postoperative tracheostomy tube management. The occurrence of major complications including deaths from routine tube changes requires an examination of the rationale and safety of this practice
