to Examine the practice characteristics of same-day clinic appointments and the use of same-day appointment scheduling to provide access to care in an otolaryngology-head and neck surgery clinic.Retrospective chart review of same-day clinic appointments from January 1, 2016, to December 31, 2018, in patients aged19 years at a single academic center. Demographic data, diagnoses, procedures completed, and operations completed were analyzed.There were 2696 visits by 2324 patients during the 3-year study period. More men than women (57% vs 43%) made same-day appointments. The mean age was 50.7 years (range, 19-99 years). Sinonasal and otologic diagnoses were the most frequently coded. A total of 1452 procedures were completed on the day of the visit, and 239 operations were completed as a result of the visit. Overall, a broad spectrum of otolaryngology care was delivered within the organizational new patient access goals.Access to otolaryngology-head and neck surgery care can be challenging. Many patients will seek care when they feel they need it, and patient conditions can change unexpectedly. Offering same-day scheduling can allow patients timely health care and appropriate care.Same-day appointment scheduling can provide access to care and urgent care for patients. The department of otolaryngology-head and neck surgery has been able to maintain a high rate of providing new patient appointments within 10 days with this method. Further considerations for the impact of same-day scheduling on no-show rates and patient satisfaction can be evaluated.

Objectives/Hypothesis To study the complication rates of skin overgrowth, infection, and the need for revision surgery in longer length Baha™ abutments. Study Design Prospective observational cohort study compared with a retrospective historical control. Methods After the University of Nebraska Medical Center (UNMC) Institutional Review Board approval was obtained, data was collected from a prospective 8.5-mm abutment study group of 21 subjects with informed consent from October 2011 through October 2012, and was compared to a retrospective 5.5-mm abutment historical cohort of 23 patients who had undergone Baha™ by the same surgeon from May 2010 to October 2011. Patient demographics, body mass index (BMI), smoking status, and wound complications (skin overgrowth, infection, the need for revision surgery) were statistically investigated and compared between the groups. Results Forty-four patients were studied. The groups were similar in smoking status, diabetes, and a female preponderance. The 8.5-mm abutment group was older (P = 0.012). The average BMI for both groups was classified as overweight and nearly obese (BMI 28.8). Rates of infection, skin overgrowth, and the need for revision surgery related to wound complications were significantly decreased in the longer 8.5-mm abutment group (P = 0.020, P = 0.012, P = 0.007, respectively). BMI did not correlate with decreased infection, skin overgrowth, and the need for revision surgery based on abutment length as hypothesized (P = 0.214, P = 0.206, P = 0.408). Conclusions The 8.5-mm abutment lends to decreased complications postoperatively, including infection, skin overgrowth, and the need for revision surgery. Level of Evidence 3b.

Objective To assess the efficacy and safety of endoscopic management of subglottic stenosis both as a primary and as an adjunctive treatment in the pediatric population. Methods Retrospective review of pediatric patients with subglottic stenosis undergoing endoscopic airway procedures at a tertiary care pediatric medical center. Outcomes were assessed by systematic review to determine the success and failure of the endoscopic approach. Results Forty patients (22 male, 18 female) underwent endoscopic interventions for a diagnosis of subglottic airway stenosis between 2003 and 2006. Age ranged from 22 days old to 20 years old. Recorded degree of subglottic stenosis ranged from 10% to 99%. Fifty-three percent (21/40) had a history of prematurity, and 40% (16/40) had secondary airway diagnoses. Twenty-four patients underwent an endoscopic intervention initially (including laser or dilation, with or without topical mitomycin treatment), including four patients who underwent tracheostomy prior to the first endoscopic intervention. Sixteen underwent laryngotracheoplasty initially, including ten patients who underwent tracheostomy prior to the laryngotracheoplasty. Endoscopic treatment resulted in resolution of symptoms, and/or decannulation, and no further need for an open procedure in 58% of patients. Of the 24 patients undergoing endoscopic interventions initially, 14 patients underwent two or more endoscopic interventions, and 10 patients subsequently required tracheostomy or laryngotracheoplasty. When endoscopic procedures were used as an adjunct to laryngotracheoplasty, 60% (12/20) had resolution of symptoms, underwent decannulation, and did not require tracheostomy or revision laryngotracheoplasty. Conclusions The endoscopic approach can be successful in the management of properly selected patients with subglottic stenosis, either as the initial treatment modality or as an adjunctive treatment in cases of re-stenosis after open airway surgery. The likelihood of success with a minimally invasive procedure as the primary treatment decreases with worsening initial grade of subglottic stenosis.

Objective. To compare postoperative pain scores between monopolar electrocautery and coblation subcapsular tonsillectomy.Study Design. Prospective double-blind randomized study.Setting. Tertiary care children’s hospital.Subjects and Methods. Between December 2004 and April 2008, 61 children, ages 4 to 20 years (mean age, 10 years; SD, 4 years), were randomized to have one tonsil removed by electrocautery and the other tonsil removed by coblation. Subjects used the FACES scale to rate pain on each side immediately postoperatively, 2 days postoperatively, and 2 weeks postoperatively. Postoperative hemorrhage was also tracked.Results. Coblation tonsillectomy resulted in statistically less pain than electrocautery immediately after surgery, but this difference was not clinically significant.Conclusions. Pediatric pain is similar following monopolar electrocautery or coblation subcapsular tonsillectomy.

BACKGROUND: The true rate of neurologic sequelae and infection from penetrating palatal trauma in children is unknown, which leads to significant variation in testing and treatment. OBJECTIVES: To (1) determine the incidence of stroke and infection in well-appearing children with penetrating palatal trauma and (2) describe patterns of testing and treatment for uncomplicated palatal trauma. METHODS: We assembled a retrospective cohort of children aged 9 months to 18 years with palatal trauma seen in the emergency department (ED) at a tertiary care pediatric hospital. Patients met the following definition: well-appearing with normal neurologic examination and a palate laceration but no findings requiring immediate operative care. Stroke was defined as any abnormal neurologic examination secondary to palatal trauma. Infection was defined as cellulitis or abscess secondary to palatal injury. All abnormal computed tomographic angiography (CTA) findings, except for free air, were considered positive and potentially significant. RESULTS: We identified 1656 potential subjects. A total of 995 of 1656 subjects were screened, and 205 of 995 met the case definition. A total of 122 of 205 had follow-up through at least 1 week after injury. The incidence of stroke in our study population was 0% (95% confidence interval [CI]: 0–2.5). One of 116 patients developed infection, for an incidence of 0.9% (95% CI: 0–5.3). A total of 90 of 205 (44%) subjects had CTA scans; the results of 9 (10%) were positive. No patients with positive CTA findings required operative care. No patients received anticoagulant medications. CONCLUSIONS: The incidence of morbidity from penetrating palatal trauma in the well-appearing child is extremely low. Diagnostic evaluation in the ED did not prompt clinical interventions other than antibiotics.

Objective Determine if passive smoke exposure (PSE) increases airway complications during outpatient mask anesthesia procedures in children. Methods A prospective cohort of children who underwent surgical procedures under mask anesthesia was studied with the American Thoracic Society children’s questionnaire on environmental and respiratory factors. Double-blinded outcomes with respect to adverse airway events were recorded both intraoperatively and in the recovery room for patients with and without passive smoke exposure. Multivariate comparisons assessing the likelihood of these airway complications were conducted between the PSE and nonexposed groups. Results Of 405 children, 168 (41.5%) had PSE. The incidence of airway complications during anesthesia or postanesthetic recovery was higher for all outcome measures for PSE children (all P ≤ 0.005), except for recovery room breath holding ( P = 0.086). Intraoperative laryngospasm and airway obstruction were 4.9 and 2.8 times more likely with PSE, respectively. Conclusions PSE significantly increases the risk of anesthesia-related airway complications during outpatient pediatric procedures. EBM rating: A-1b

Objective To describe the epidemiology, natural history, and treatment of epiglottitis in the Hemophilus influenzae type B (Hib) vaccine era. Design Ten-year retrospective study. Setting Tertiary-care children's hospital. Patients Nineteen patients with a discharge diagnosis of epiglottitis. Intervention As indicated by the presentation of the patient, including direct laryngoscopy, intubation, intravenous antibiotics, and steroids. Main outcome measures Presentation, management, and microbiology. Results Presenting symptoms included fever, drooling, and hot potato voice. Patients' ages ranged from 15.8 months to 17.5 (mean 8.9) years. From 1992 to 1997, the mean age was 5.8 years; from 1998 to 2002, the mean age was 11.6 years. Sixty-eight percent of patients were transferred from an outside hospital. A lateral neck radiograph was recorded in 84% of patients. Mean leukocyte count was 16,600. Direct laryngoscopy with intubation was performed in 79%; intubation was for an average of 3.5 days. H. influenzae was cultured in six patients, five of which had up-to-date immunizations. The most commonly administered antibiotics were ampicillin/sulbactam and ceftriaxone. Steroids were administered to 63% of patients. Complications included deep neck space infection (2), seizure (1), recurrent illness (1), and vocal granuloma (1). There were no deaths. Conclusion The demographics, causative organisms, and natural history of epiglottitis have changed substantially in the Hib vaccination era. The clinician evaluating and treating patients with epiglottitis should be aware of current trends.

The management of a mastoid subperiosteal abscess has traditionally required mastoidectomy. With the improvement of antibiotic therapy current literature supports the treatment of uncomplicated acute mastoiditis with myringotomy and intravenous antibiotics. Treatment of a mastoid subperiosteal abscess with tympanostomy tube insertion, intravenous antibiotics, and postauricular incision and drainage of the abscess avoids the morbidity and potential complications of mastoid surgery in young children. Three patients diagnosed with a mastoid subperiosteal abscess were managed in this way. The outcome of their treatment has been documented with lengthy otologic follow-up. Complete resolution of the acute infectious process was achieved in all cases with no evidence of recurrent disease.

Objective: To examine the effects of endoscopic sinus surgery on the pulmonary status of cystic fibrosis (CF) patients through the objective parameters of steroid use, pulmonary function tests (PFTs), and inpatient hospital days (IHDs). Methods: Retrospective chart review of all patients with CF who underwent endoscopic sinus surgery from 1993 to 1999 at a tertiary care children's hospital. Preoperative pulmonary function, inhaler and steroid use, and IHDs were compared to postoperative parameters within a 1-year period. Results: Sixty-six patients, including eight lung transplant patients, underwent a total of 112 endoscopic sinus surgery procedures; 25 patients underwent more than one procedure. Patients were taking oral steroids preoperatively in 28% of procedures and inhaled steroids in 40%. Postoperatively, there was no statistically significant change in oral or inhaled steroid use, or in postoperative pulmonary function. If the index hospitalization, which was often for reasons not related to sinus disease, was considered part of the preoperative time period, endoscopic sinus surgery (ESS) was noted to result in a marked reduction (9.5 days (adjusted), P =0.001) in hospital days during the subsequent 6 months. If the date of the procedure alone was used to define pre- and postoperative time periods, the reduction in postoperative days was more modest and not statistically significant (3.5 days (adjusted), P =0.21). Conclusions: Although we found no statistically significant difference in PFTs, or steroid requirements following ESS, ESS may have resulted in a reduced need for hospitalization in the 6 months following the procedure. Future prospective studies in a larger number of patients and using more detailed outcome measures are needed to better evaluate the effects of endoscopic sinus surgery in pediatric patients with CF.

Background: Persistent nasolacrimal duct obstruction (NLDO) often requires treatment by probing, intubation, or balloon dacryoplasty. Refractory cases have been managed by external dacryocystorhinostomy (DCR), which leaves a scar; however, this procedure is generally avoided in young children. Endoscopic DCR has been successfully performed in adults and described in children. We report the success of this procedure in a series of pediatric patients. Methods: A retrospective review of all endoscopic lacrimal procedures performed in a 3-year period was undertaken. Seventeen children (22 ducts) with persistent NLDO after at least one failed probing, with or without silicone tube placement, underwent endoscopic DCR. Follow-up ranged from 6 to 36 months, and success was defined as resolution of tearing and discharge by follow-up clinical evaluation and by parental history. Results: All but 2 patients (88%) with NLDO showed complete resolution of tearing and discharge. These 2 patients had recurrent symptoms after the Crawford tubes were removed and required revision endoscopic DCR. No complications from this procedure were noted. Conclusions: Endoscopic DCR is a safe and effective means of treating persistent NLDO in infants and young children when simple probing, intubation, or balloon procedures have failed. The team ophthalmology-otolaryngology endoscopic approach provides a highly successful alternative for patients with a persistent distal obstruction that might otherwise require an external procedure.

Because the biomechanical competence of the graft is a central issue, many research studies of bone grafts include a biomechanical component. The biomechanical evaluation serves as a bottom-line measure of the experimental outcome in which some measure of mechanical performance is compared among treatment groups. This article considers the biomechanics of grafts in the context of this experimental work and focuses on three issues: (1) the interplay between biology and biomechanics of grafts, (2) the effects of treatment choices on biomechanical properties, and (3) model factors that may influence biomechanical performance.

From 1982 to 1984, the authors conducted a population-based case-control study of lung cancer in men and women nonsmokers in New York State. In-person interviews were completed for 437 lung cancer cases (197 never smokers, 240 former smokers) and 437 matched population controls. Cases and controls were asked to report any history of physician-diagnosed nonmalignant lung disease; cases were more likely than controls to report such a history. Statistically significant associations were found for emphysema (odds ratio (OR) = 1.94, 95% confidence interval (CI) 1.10-3.43), chronic bronchitis (OR = 1.73, 95% CI 1.10-2.72), and the combined endpoint of emphysema, chronic bronchitis, or asthma (OR = 1.82, 95% CI 1.26-2.63). After adjustment for active and passive tobacco smoke exposure, emphysema, chronic bronchitis, and asthma (each condition and the combined endpoint) were significantly associated with lung cancer risk. The risk was more marked for squamous cell carcinomas and for subjects who were diagnosed at older ages, and it remained significant when surrogate interviews were excluded. These results are consistent with the hypothesis that certain prior lung conditions increase the risk of lung cancer in men and women nonsmokers.

Background: The International (formerly National) Bariatric Surgery Registry began collecting data in January 1986. The aim of this study was to examine changes in the practice of surgical treatment of severe obesity that occurred during the decade of 1986 through 1995, as observed in the IBSR data. Methods: All data submitted to the IBSR during the decade were transferred to the IBM mainframe computer for analysis. Characteristics of operative type populations were compared over time using analysis of variance (ANOVA) for age, body mass index (BMI), operative weight and Chi-square (χ2) test for gender. Results: There has been a steady increase over the decade in mean patient weight. The operations used have changed from predominantly ‘simple’ operations to more frequent use of ‘complex’ operations. Within the categories of ‘simple’ and ‘complex’, an increase in the variety of operations occurred. As a group, patients with ‘simple’ operations have been heavier, more often male and public pay patients than those who have undergone ‘complex’ operations. One year weight loss was greater for Roux-en-Y gastric bypass (RGB) than vertical banded gastroplasty (VBG), but follow-up rates were too low to study the relative merits of the operations used. The reported incidence of operative mortality and serious complications (leak with peritonitis, abscess and pulmonary embolism) remained low. Conclusions: These observations and their implications can be summarized in three statements which relate to action for improved patient care in the beginning of the new century: (1) increasing weight of candidates for surgical treatment during this decade indicates the need for earlier use of operative treatment before irreversible complications of obesity can develop; (2) low risk of obesity surgery, decreasing postoperative hospital stay, and early weight control support the continued and increased use of surgical treatment; (3) continued widespread use of both ‘simple’ and ‘complex’ operations with increased modifications of standard RGB and VBG procedures emphasizes the need for standardized long-term data and analyses regarding both weight control and postoperative side-effects.

Objectives:Evaluate the effect of increasing blood alcohol concentration (BAC) on the vestibular system as measured by abnormal body sway on posturography. Determine if there is a consistent level of BAC during which sway becomes adversely affected, as suggested by legal state limits of BAC for driving.Methods:Prospective study of 30 healthy adults randomized to alcohol versus no alcohol who consumed one beverage hourly followed by BAC measurement by BACtrack Select S80 Breathalyzer and posturography on both firm/soft surfaces with eyes open/closed. Primary outcome was dose-response rate of BAC on mean body sway. Nonlinear growth models were used to control for covariates.Results:The experimental (alcohol) group had 20 adults, and the control (no alcohol) group had 10 adults. BAC levels measured by breathalyzer ranged from 0 to 0.12. Overall analysis showed no statistically significant difference between male and female performance (P > 0.05). Increased alcohol consumption was associated with increased ab...

M IN IS E M IN A R S stapedectomies in the past were undoubtedly performed on ears with occult third window syndromes. We will present a review of superior SCD and other third window syndromes, with an emphasis on differentiating them from more common otologic diagnoses. Cases will be presented that illustrate how these syndromes should be included in the differential diagnosis of many common otologic presentations. SCD, the most common third window syndrome, will be discussed in detail, including diagnosis and treatment indications, options, and outcomes.

The immunodeficient child presents a unique challenge to the otolaryngologist, who must be able to recognize the early stages of immunodeficiency as well as be a consultant in later stages of the disease. Infection by HIV has brought about a new era both in the magnitude of immunodeficiency seen and in our understanding of the mechanisms of immune function. The current literature concerning HIV-infected children with manifestations in the head and neck is reviewed. Many similarities between HIV-infected children and other immunosuppressed patients have emerged, and salient features of immunodeficiency diseases of childhood are examined.

BACKGROUND Approximately 15% of all lung cancer deaths in the United States (about 22,350 deaths annually) may not be directly attributable to active cigarette smoking. Consumption of beta carotene, which is derived almost exclusively from intake of fruits and vegetables, has been associated with a reduced risk of lung cancer in smokers. However, studies examining this association in nonsmokers, particularly nonsmoking men, are limited. PURPOSE The purpose of this study was to examine whether dietary factors including beta carotene and retinol are associated with a reduced risk for lung cancer in nonsmoking men and women. METHODS A population-based, matched case-control study of lung cancer in nonsmokers was conducted in New York State from 1982 to 1985. Dietary interviews were completed for 413 individually matched case-control pairs of subjects. To determine whether the relationship between dietary intake from specific food groups and lung cancer differed by type of interview, smoking history, sex, age, or histologic type, we examined data on the case-control pairs from each subgroup separately. The intake of beta carotene and retinol was calculated as the weighted sum of the monthly frequencies of consumption of food items containing these nutrients, where the weights correspond to the nutrient content of a typical portion of the food items. RESULTS Consumption of greens (P for trend < .01), fresh fruits (P for trend < .01), and cheese (P for trend < .05) was associated with a significant dose-dependent reduction in risk for lung cancer, whereas consumption of whole milk (P for trend < .01) was associated with a significant dose-dependent increase in risk. Use of vitamin E supplements was also protective (odds ratio = 0.55; 95% confidence interval [CI] = 0.35-0.85). Increased consumption of the following food groups was associated with a reduction in risk among females: vegetables (P for trend < .025), raw fruits and vegetables (P for trend < .005), and dairy products (P for trend < .025). In males, increased consumption of raw fruits and vegetables was associated with a reduced risk for lung cancer (P for trend < .005). Dietary beta carotene (OR = 0.70; 95% CI = 0.50-0.99), but not retinol (OR = 0.98; 95% CI = 0.82-1.17), was significantly associated with risk reduction. CONCLUSIONS This is the largest study to date of dietary factors and lung cancer in nonsmokers; results suggest that dietary beta carotene, raw fruits and vegetables, and vitamin E supplements reduce the risk of lung cancer in nonsmoking men and women.

Hemangioma is a well-recognized cause of airway obstruction in the infant with stridor. Corticosteroid and laser therapy are effective in stabilizing the airway in most cases. There are, however, some extensive airway lesions that are not adequately managed by these modalities. This report describes the use of recombinant interferon alfa-2a in 15 patients with life-threatening airway hemangiomas. All patients had failed corticosteroid and/or laser therapy. Multiple upper airway sites were involved, including the base of the tongue, supraglottis, subglottis, trachea, and mediastinum. Eleven patients have completed therapy and are doing well. Four patients have resolving lesions on the drug regimen. Life-threatening airway lesions unresponsive to conventional treatment should be considered for a trial of interferon alfa-2a.

Objectives To review the characteristic microbiology of the paranasal sinuses in patients with cystic fibrosis who undergo endoscopic sinus surgery. To examine the subtypes of organisms cultured from the maxillary sinuses and determine their sensitivity to antibiotic therapy. Study design Retrospective chart review. Setting Tertiary care children's hospital. Methods Sinus cultures were obtained from 51 patients with cystic fibrosis during endoscopic sinus procedures between 2000 and 2004 at a tertiary care children's hospital. A retrospective chart review was undertaken to obtain culture and sensitivity data of the sinus contents. Results The most common bacteria isolated was Staphylococcus aureus (71%), followed by Pseudomonas aeruginosa (PSA) (27%), Haemophilus influenzae (21%), Staphylococcus non-aureus (16%) and Streptococcus viridans (12%). Streptococcus pneumoniae and Moraxella catarrhalis were rarely isolated (2% and 0% respectively). Twenty-nine percent of the patients with cultures positive for PSA were of the mucoid variant. Only one patient had culture positive Escherichia coli. Antibiotic resistance among the more common organisms cultured from the sinus samples is also listed. Conclusion Staph. aureus is the most common isolate in the sinuses of this pediatric CF population followed by P. aeruginosa and H. influenzae. Although many isolates are pansensitive, some isolates are panresistant.

We studied the biomechanical behavior of orthotopic canine autografts as influenced by vascularized supply and the administration of cyclosporin A at three months and six months post-surgery. The model was the proximal 8 cm of the fibula in young adult dogs. In vascularized grafts, blood supply was re-established by microvascular re-anastamosis. Experimental controls were sham-operated and unoperated bones. Mid-graft test sections were subjected to loading-to-failure in torsion to determine the strength and stiffness. In both three- and six-month groups, vascularized grafts were significantly stronger and stiffer than contralateral nonvascularized grafts. Vascularized grafts were not significantly different from sham-operated bones. A 30-day regimen of cyclosporin A was found to have no measurable effect on mechanical properties for any individual treatment group. The results indicate that re-established blood supply can be a major factor in maintaining the mechanical integrity in large-segment cortical autografts.

Cerebrospinal fluid leaks can be difficult management problems. Little information has been published about handling these cases in the pediatric population. A review of cases over the past 10 years at Boston Children's Hospital was undertaken to identify any prognostic factors and therapeutic recommendations. Twenty-seven patients were identified. While most patients responded to conservative therapy, those with leaks that persisted longer than 8 days required some type of operative closure. Severity of injury had little correlation with the occurrence of a leak. The findings in this study indicate that most pediatric cases can be managed on a conservative basis.

Objective The use of image guidance for sinonasal and skull base surgery has been well-characterized in adults but there is limited information on the use of these systems in the pediatric population, despite their widespread use. The aim of this study is to evaluate the use of image guidance systems to facilitate an endoscopic minimally invasive approach to sinonasal and skull base surgery in a pediatric population. Methods A retrospective cohort study was performed at a tertiary pediatric hospital. Thirty-three children presented with complications of sinusitis, tumors, traumatic, or congenital lesions of the skull base and underwent endoscopic surgery using image guidance from March 2000 to April 2007. Patient variables including diagnosis, extent of disease, and complications were extracted from paper and computer charts. Additional surgical variables including set-up time, accuracy, surgeon satisfaction index and number of uses per case were also reviewed. Results Twenty-eight patients (85%) underwent sinonasal surgery and five (15%) underwent skull base surgery. Indications included infectious complications of acute sinusitis ( N = 15), neoplasms ( N = 12), choanal atresia ( N = 4), and cerebrospinal fluid leak ( N = 2). Thirty-one patients (94%) required only one procedure. No surgical complications were reported. Surgeon satisfaction, mean accuracy and number of uses per procedure increased over time ( p Conclusions Image guidance systems are safe and effective tools that facilitate a minimally invasive approach to sinonasal and skull base surgery in children. Consistent with adult literature, usage and surgeon comfort increased with experience. The additional anatomical information obtained by image guidance systems facilitates a minimally invasive endoscopic approach for sinonasal and skull base pathologies.

To determine the prevalence of sensorineural hearing loss (SNHL) in cystic fibrosis (CF) patients and its relationship to antibiotic use.Case series with chart review.Tertiary care pediatric hospital.We reviewed the medical records of CF patients seen in our children's hospital between March 1994 and December 2007. Data collected included patient demographics, audiograms, tympanograms, genotype, and use of potentially ototoxic antibiotics.Seven of 50 (14%) patients had SNHL. Three percent of patients who receivedor=10 courses of intravenous aminoglycosides had SNHL versus 43 percent of those who received10 courses (P0.01). No patients who received five or fewer courses of nasal irrigation with aminoglycosides had SNHL versus 23 percent of those who received more than five courses (P0.05). Nine percent of patients who received five or fewer courses of macrolides had SNHL versus 60 percent of those who received more than five courses (P=0.079).CF patients receiving aminoglycosides are at high risk for developing SNHL.

The early (3 months) and later (6 months) patterns of incorporation and bone formation have been evaluated fiistomorphometrically for different types of bone grafts; that is, vascularized and nonvascularized autografts with and without ciclosporin, and vascularized and nonvascularized dog leukocyte antigen (DLA)-mismatched allografts with and without ciclosporin. The vascularized bones were superior to the nonvascularized ones in healing and remodeling their grafted segments. In the autograft bones ciclosporin did not alter the incorporation process 3 months after transplantation but delayed and increased the remodeling activities in the long run (6 months). Nonvascularized allografts underwent vigorous resorption, and were markedly porotic. Ciclosporin administration significantly reduced resorption and enhanced remodeling in nonvascularized allografts. The remodeling of allografts was similar to that of autografts in the presence of ciclosporin, but stopped soon after the administration of ciclosporin ceased.

OBJECTIVE: To determine the efficacy of a preoperative bleeding questionnaire (POBQ) and coagulation screening in predicting hemorrhage associated with adenotonsillectomy. STUDY DESIGN: Retrospective study. SUBJECTS AND METHODS: Between January 1998 and December 2003, 7730 tonsillectomy and adenotonsillectomy patients were administered the POBQ preoperatively. Further coagulation screening was based on POBQ responses. RESULTS: A total of 232 (3.0%) of 7730 had postoperative bleeding; 184 (3.2%) of 5782 patients who had negative questionnaires bled postoperatively compared with 48 (2.5%) of 1948 patients with positive questionnaires (P = 0.126). Of 1948 patients with positive questionnaires, 141 (7.2%) had abnormal preoperative coagulation screens and 9 (6.4%) of 141 bled; of the 1807 (92.8%) with negative coagulation screens, 39 (2.2%) bled (P = 0.005). CONCLUSION: The POBQ is an effective tool for identifying patients who are at potential risk for post-tonsillectomy bleeding. Patients with both a positive POBQ and coagulation screen had a statistically higher likelihood of postoperative bleeding than other patients. The POBQ allowed the identification of individuals with bleeding disorders to be treated before surgery, likely decreasing the risk of bleeding in these patients.

Objective To assess the benefits of adenotonsillectomy in the treatment of pediatric patients with PFAPA (periodic fever, aphthous ulcers, pharyngitis, and adenitis) syndrome. Design Prospective case series. Setting Tertiary care pediatric hospital. Patients Pediatric patients meeting criteria for PFAPA syndrome. Intervention Tonsillectomy with or without adenoidectomy. Main Outcome Measure Resolution of PFAPA symptoms. Results Twenty-seven (14 female, 13 male) children with PFAPA syndrome underwent tonsillectomy with or without adenoidectomy from 2004 through 2006. The length of follow-up for all patients ranged from 8 to 41 months. A total of 26 patients experienced a complete resolution of their symptoms. The 1 child who continued to have febrile episodes had fever cycles that were not regular in duration or interval and in hindsight was not likely a patient with PFAPA syndrome. Conclusions Our findings showed complete resolution of symptoms in 26 of 27 patients with PFAPA syndrome treated surgically. Patients who meet clinical criteria for PFAPA syndrome should be considered for tonsillectomy and adenoidectomy if they do not respond to medical management.

The biological and biomechanical properties of normal fibulae, fibulae that had had a sham operation, and both vascularized and non-vascularized autogenous grafts were studied in dogs at three months after the operation. The study was designed to quantify and correlate changes in these properties in orthotopic, stably fixed, weight-bearing grafts and to provide a baseline for additional studies of allografts. The grafts were eight centimeters long and internally fixed. The mechanical properties of the grafts were studied by torsional testing. Metabolic turnover of the grafts was evaluated by preoperative labeling of the dogs with 3H-tetracycline for resorption of bone mineral and with 3H-proline for turnover of collagen. Cortical bone area and porosity were measured. Postoperative formation of bone was evaluated by sequential labeling with fluorochrome. The vascularized grafts resembled the fibulae that had had a sham operation and those that had not had an operation with regard to the total number of osteons and the remodeling process, as measured both morphometrically and metabolically. The vascularized grafts were stronger and stiffer than the non-vascularized grafts and were not different from the bones that had had a sham operation. In contrast, the non-vascularized grafts were smaller, weaker, less stiff, and more porotic, had fewer osteons, and demonstrated increased turnover and resorption compared with the vascularized grafts, the bones that had had a sham operation, and the bones that had not been operated on.

We studied the mechanical, metabolic, and histologic properties of short-term nonvascularized cortical bone grafts in a canine fibular graft model. Sham operated nonvascularized autotransplanted and allotransplanted bones were compared. The allografts were performed between dog leukocyte antigen (DLA) class I and II matched; DLA class I and II mismatched; and cyclosporin A (CsA) treated, DLA class I and II mismatched animals. Cyclosporin was given for 1 month, and all the animals were followed for 3 months after surgery. Mechanical properties were investigated using standard torsional tests, metabolic kinetics were assessed using isotopic prelabeling techniques, and histomorphometric analysis of cross-sectional area properties and sequential fluorochrome labels were performed. Autografts were mechanically stronger and stiffer than all the types of allograft. CsA-treated, DLA-mismatched allografts performed better than matched allografts. These in turn were stronger than non-CsA-treated, mismatched allografts, which underwent nearly complete resorption. These relationships were preserved in the metabolic and histologic analyses. In this short-term animal study, although DLA matching resulted in a slight improvement in graft outcome, mismatched grafts in dogs receiving a short course of cyclosporin A fared even better.

Objective To evaluate the effectiveness of follow-up telephone interviews and questionnaires after tonsillectomy and adenoidectomy. Design Cohort study and retrospective review of the outcomes of patients whose follow-ups were conducted by telephone interview. Patients were contacted 2 to 4 weeks after surgery; responses were recorded on a standardized postoperative questionnaire. Setting Tertiary pediatric hospital. Patients A total of 2554 consecutive patients who had undergone tonsillectomy, adenoidectomy, or both procedures and completed a follow-up telephone interview during the period of January 8, 2000, to September 23, 2004. Main Outcome Measures Time to return to normal diet and activities, postoperative complications, pain management, postoperative visits, and caregiver's evaluation of the follow-up telephone survey. Results A total of 2554 patient outcomes were reviewed. The mean patient age was 5.9 years. Follow-up contact occurred a mean of 24.1 days after surgery. Of the surgical procedures performed, there were 1957 adenotonsillectomies, 235 adenoidectomies, and 362 tonsillectomies. At the time of follow-up, 2.7% of the patients had undergone an additional surgical procedure to treat postoperative bleeding, 96.9% had resumed eating a normal diet, and 96.2% had resumed normal activities. Bleeding from the nose or mouth was reported to have occurred at some point during the recovery period in 12.8%. On a pain scale of 1 to 10, a mean pain peak of 6.7 was reported. For most patients, pain was highest on the second day after surgery. The percentage of patients who had temporary voice change was 62.7%, and 15.4% had a follow-up clinic visit. Regarding caregivers, 99.5% reported being given instructions for postoperative care, and 98.8% reported that they felt well prepared to care for their child at home. There were no adverse events reported from surgical intervention. Conclusions Compared with our previous experience with scheduled postsurgical clinic follow-ups, telephone interviews and standardized postoperative questionnaires pose no additional risk to patients. Considerable cost reduction and patient convenience were realized with a reduction of patient visits.

Background Vocal cord dysfunction (VCD) is an increasingly recognized condition that affects the upper airway, which can be difficult to discriminate from asthma. Speech therapy and psychological cognitive therapy are the mainstays of treatment, but other modalities have been used when response is unsatisfactory. Objective To present 2 case studies in which VCD has been treated with long-term tracheostomy. Methods In the first patient, VCD was diagnosed by nasoendoscopic demonstration of paradoxical movement of the vocal cords. The patient was transferred to a regional unit, where nasoendoscopy was performed, which revealed immobile and adducted vocal cords. The decision to perform emergency surgical tracheostomy was made. In the second patient, a possible additional diagnosis of VCD was suggested during a hospital stay, and nasoendoscopy was performed. Results Both patients report considerable subjective benefits. Objective improvement was seen in only one patient. Conclusions Tracheostomy is an invasive procedure that carries risk of potential morbidity and should only be considered as a final option in carefully selected cases.

Context. Children frequently ingest coins. When lodged in the esophagus, the coin may cause complications and must either be removed or observed to pass spontaneously.Objectives. (1) To compare relatively immediate endoscopic removal to a period of observation followed by removal when necessary and (2) to evaluate the relationship between select clinical features and spontaneous passage.Design/Setting. Randomized, prospective study of children 24 hours earlier. Children were randomized to either endoscopic removal (surgery) or admission for observation, with repeat radiographs ∼16 hours after the initial image.Outcome Measures. Proportion of patients requiring endoscopic removal, length of hospital stay, and the number of complications observed.Results. Among 168 children who presented with esophageal coins lodged in the esophagus, 81 were eligible. Of those eligible, 60 enrolled, 20 refused consent, and 1 was not approached. In the observation group, 23 of 30 (77%) children required endoscopy compared with 21 of 30 (70%) in the surgical group. Total hospital length of stay was longer in the randomized-to-observation group compared with the randomized-to-surgery group (mean: 19.4 [SD: ±8.0] hours vs 10.7 [SD: ±7.1] hours, respectively). There were no complications in either group. Spontaneous passage occurred at similar rates in both groups (23% vs 30%). Spontaneous passage was more likely in older patients (66 vs 46 months) and male patients (odds ratio: 3.7; 95% confidence interval: 0.98–13.99) and more likely to occur when the coin was in the distal one third of the esophagus (56% vs 27% [95% confidence interval: 1.07–5.57]).Conclusions. Because 25% to 30% of esophageal coins in children will pass spontaneously without complications, treatment of these patients may reasonably include a period of observation, in the range of 8 to 16 hours, particularly among older children and those with distally located coins.

To determine the accuracy of computed tomography (CT) in the diagnosis of pediatric chronic rhinosinusitis (CRS).Multi-institutional prospective dual cohort study.Two cohorts of children undergoing CT of the paranasal sinuses were prospectively evaluated. The first cohort consisted of children undergoing CT in preparation for endoscopic sinus surgery (diseased group). The second cohort consisted of children undergoing CT for nonsinusitis reasons (nondiseased control group). Sinus CT scans were scored according to the Lund-MacKay system. Diagnostic accuracy was quantified with the receiver operating characteristic curve. Sensitivity, specificity, and predictive value analyses were conducted.A total of 66 pediatric patients (mean age, 8 years) were studied in the diseased group and exhibited a mean Lund score of 10.4 (95% confidence interval, 9.2-11.5); 192 control patients (mean age, 9 years) exhibited a mean Lund score of 2.8 (95% confidence interval, 2.4-3.2). The area under the curve for the receiver operating characteristic was 0.923 (P.001), indicating excellent diagnostic accuracy. Adopting a Lund score cutoff of 5 to represent true disease, the CT scan demonstrated a sensitivity and specificity of 86% and 85%, respectively. Lund scores of 2 or less have an excellent negative predictive value, whereas Lund scores of 5 or greater have an excellent positive predictive value (ie, strongly indicate true disease).The sinus CT scan demonstrates excellent diagnostic accuracy for the diagnosis of pediatric CRS, with excellent sensitivity and specificity. However, its predictive value depends substantially on the base rate prevalence of CRS in the population being evaluated.

Summary Objectives/hypothesis: Pediatric oropharyngeal trauma (OPT) is a common injury in children with rare, but at times severe complications including carotid injury and dissection of air/micro-organisms into the deep tissues of the neck or chest. Cervical CT scan with contrast (CT angiography (CTA)) is nearly universally available and may enhance the evaluation of OPT patients by screening for these potentially devastating complications. Study design: Retrospective record review, systematic review of the literature. Methods: Twenty-three patients diagnosed with OPT from 1997 to 2003 at Boston Children's Hospital were identified by database review. Records were reviewed for site and mechanism of injury, use of diagnostic studies, management, and outcomes. Results were compared to previously published reports. The current literature was reviewed to assess the level of evidence pertaining to the evaluation of OPT patients with CT scan. An extrapolation was made to the general trauma literature to further evaluate the ability of CT angiography to detect carotid injury. Results: Demographics and mechanism of injury in the current series were unchanged from previous reports. CT demonstrated superior detection and localization of free air. Systematic review of OPT literature revealed data on the use of CT scan as evaluation tool were lacking. Extrapolations to the trauma literature strongly indicate helical CTA has high sensitivity and specificity in detecting carotid injury. Conclusions: Pediatric oropharyngeal trauma is a common injury with rare, but severe complications. The routine use of CT scan with contrast may assist in the evaluation of these patients to detect injuries that could lead to severe complications. Collection of prospective data on the ability of CT scan to detect carotid injuries is needed but may not be feasible.

The purpose of this study is to evaluate the effects of radiofrequency (RF) thermal capsulorrhaphy on the kinematic properties of the glenohumeral joint as determined by changes in resistance to multidirectional translational forces, alteration in the range of internal and external rotation, and changes in glenohumeral joint volume. Nonablative RF thermal energy was used to contract the glenohumeral joint capsule in 6 cadaveric shoulders. Measurements of translation were made after application of a 30-N load in anterior, posterior, and inferior directions. The maximum arc of internal and external rotation after application of a 1-N-m moment was also determined for vented specimens before and after thermal capsulorrhaphy. The percent reduction in glenohumeral capsular volume was measured by use of a saline solution injection-aspiration technique. Capsular shrinkage resulted in reductions in anterior, posterior, and inferior translation. The largest percent reductions in anterior translation were seen in external rotation at 45 degrees (48%, P.05) and 90 degrees (41%, P.05) abduction. For inferior translation, the largest percent reductions were seen in internal rotation at 45 degrees (40%, P.05) and 90 degrees (45%, P.05) abduction. Reductions in posterior translation were noted in internal rotation at 45 degrees (27%, P.05) and 90 degrees (26%, P.05) abduction. Other changes in translation were observed but were not statistically significant. The maximum arc of humeral rotation was reduced by a mean of 14 degrees at 45 degrees abduction and 9 degrees at 90 degrees abduction. The mean percent reduction in capsular volume for all shoulders was 37% (range, 8%-50%). This could not be correlated with percent reductions in translation and rotation. This study demonstrated the significant effect of RF thermal capsulorrhaphy in reducing glenohumeral multidirectional translation and volume with only a small loss of rotation in cadaveric shoulders.

The authors assessed body mass index (BMI), measured as Quetelet's index (weight in kilograms divided by the square of height in meters), in relation to lung cancer risk in never and former smokers by using data from a population-based, individually matched, case-control study conducted in New York State from 1982 to 1985. To be included in the study, subjects must never have smoked more than 100 cigarettes in their lifetime (never smokers) or not have smoked more than 100 cigarettes during the last 10 years (former smokers). Data on height and weight were complete for 412 of 439 case-control pairs. A positive relation was found between BMI and lung cancer risk for both never smokers (188 case-control pairs) and former smokers (224 pairs). When subjects were combined, those in the eighth (highest) octile (BMI > 30.84) had more than twice the odds of being cases compared with those in the lowest octile (BMI < or =21.26, 95 percent confidence interval: 1.2, 4.4). These study results are consistent with those from studies of BMI and other cancer sites but differ from lung cancer results usually found in predominantly smoking populations.

Objective To evaluate the efficacy and cost-effectiveness of postoperative follow-up telephone calls among pediatric patients who underwent adenotonsillectomy. Design Prospective study with a follow-up questionnaire administered by telephone. Setting Tertiary-care children's hospital. Patients One hundred thirty-four children between the ages of 4 and 18 years who underwent adenotonsillectomy between December 1997 and June 1998 and did not have associated cardiac, pulmonary, bleeding, or syndromic disorders were included in this pilot study. Intervention Parents of these patients were given the opportunity to participate in our study, and it was emphasized that, at any time during the child's care, if the parent desired a follow-up visit or if the child experienced any symptoms that caused concern, the parent should contact the clinic for a follow-up appointment. A telephone call was placed 3 to 4 weeks postoperatively by an otolaryngology nurse, and a questionnaire was filled out using the parents' responses. Main Outcome Measures The incidence rates of voice change, velopharyngeal insufficiency, bleeding, constipation, dehydration, and pain were measured. Parent satisfaction, patient safety, and cost-benefit were also evaluated. Results Less than 5% of patients reported temporary velopharyngeal insufficiency, while 2% of patients required operative intervention for bleeding episodes and 1% required hospitalization. Voice change, reported by approximately 70% of all patients, was the most common complaint, but it resolved in all instances. Pain was reported to be most severe on postoperative day 1. Ninety-six percent of parents requested no further follow-up visit. Conclusions Our pilot study revealed that a follow-up telephone call is a safe and cost-effective method of postoperative management for pediatric patients who have undergone adenotonsillectomy and that this method of follow-up is also desirable to parents.

The authors studied the effects of standard processing and preprocessing low dose gamma irradiation (1.5 Mrad) on the strength and incorporation of syngeneic and allogeneic cortical bone grafts. Bilateral femoral middiaphyseal 8-mm segmental defects in 120 male Fisher rats were stabilized with internal fixation. Each defect received one of six types of grafts: fresh syngeneic, processed syngeneic, irradiated processed syngeneic, fresh allogeneic, processed allogeneic, and irradiated processed allogeneic grafts. Graft processing included soaking in 70% ethanol and deep freezing for preservation. Irradiation was performed by 60Co source immediately before processing. Grafts were evaluated by histologic analysis, histomorphometric analysis, and biomechanical testing at 4 and 6 months after surgery. Graft treatment, either processing or irradiation processing, did not affect consistently or significantly the incorporation of syngeneic or allogeneic grafts. Graft allogenicity was the major determinant of the revascularization and the histologic pattern of graft incorporation. Processed and irradiated processed allogeneic grafts gained compressive strength with time and were as strong as syngeneic grafts at 6 months. Biomechanical and histologic data from this study suggest that standard processing and preprocessing low dose irradiation do not compromise the natural course of allogeneic cortical bone graft incorporation.

To evaluate the treatment, perioperative management, and outcome of infants who underwent repair of congenital tracheal stenosis. We hypothesized that early resection and tracheoplasty with early weaning of ventilatory support results in less mucosal injury, and thus better outcome.Retrospective study from 1986 to 1996.Tertiary care children's hospital.Seventeen consecutive infants with congenital tracheal stenosis, aged from birth to 16 months. Fifteen patients had complete tracheal rings, 6 of whom also had a left pulmonary artery sling. Fourteen patients underwent either tracheoplasty or resection and reanastomosis of the trachea, both facilitated by cardiopulmonary bypass.Six patients underwent resection and reanastomosis; 4 patients were extubated within 2 to 5 days without sequelae. There was 1 unrelated perioperative death. Two patients required reintubation. Eight patients required tracheoplasty due to severe tracheal stenosis and had variable postoperative courses. Seven of 14 patients required 0 to 1 postoperative bronchoscopies. Seven of 14 patients required 2 to 7 bronchoscopies for granulation tissue formation, cicatrix, graft collapse, and tracheitis. One patient required numerous procedures and revision tracheoplasty for cicatrix and stenosis.Correction of short-segment (5 rings) tracheal stenosis by resection and reanastomosis of the trachea with the aid of cardiopulmonary bypass and early weaning of ventilatory support is recommended. Tracheoplasty using either the castellation technique or slide tracheoplasty is recommended in the treatment of infants with severe (long segment) tracheal stenosis.
