Program directors' opinions about surgical competency in otolaryngology residents.

OBJECTIVES: The purpose of this study was to determine whether certain surgical procedures could be used as benchmark skills to monitor resident progress in developing surgical competency. STUDY DESIGN: Survey. METHODS: A two-stage survey was sent to otolaryngology residency program directors in the United States. Respondents were given a list of otolaryngology surgical procedures monitored by the American Board of Otolaryngology (ABO) and were asked to indicate whether they felt residents should be able to do each as a primary surgeon. The appropriate level of training for competency in each procedure and estimated number of procedures to competency was indicated by respondents. RESULTS: Respondents selected 16 common procedures they felt residents at different levels of training should be able to perform independently. There were discrepancies between estimated number of procedures needed for competence and the numbers reported by ABO graduates. CONCLUSIONS: Surgical skill is one aspect of clinical competency, and this indicates agreement among program directors with regard to a set of benchmark skills we can use for concentrated evaluation efforts.

Correlation of findings at direct laryngoscopy and bronchoscopy with gastroesophageal reflux disease in children: a prospective study.

OBJECTIVE: To correlate direct laryngoscopic and bronchoscopic findings with the presence of positive test results for gastroesophageal reflux disease (GERD) in children. DESIGN: Prospective collection of structured data. SETTING: An academic pediatric otolaryngology department. PATIENTS: Seventy-seven consecutive patients who underwent direct laryngoscopy and bronchoscopy between June and October 1999. INTERVENTIONS: During direct laryngoscopy and bronchoscopy, descriptions of 7 laryngeal and 6 cricotracheal findings were recorded on a 3-point scale (i.e., absent, mild, or severe). Medical records were later reviewed to obtain results of the following tests, if they were part of the record: gastric scintiscan, 24-hour pH probe monitoring, upper gastrointestinal tract series, and esophageal biopsy. MAIN OUTCOME MEASURES: Correlation of mucosal abnormalities with the presence or absence of a positive test result for GERD. RESULTS: Fifty (65%) of 77 patients had GERD diagnosed with at least 1 positive test result, 21 (27%) had no clinical symptoms and no positive GERD test results, and 5 (7%) had clinical symptoms but no positive test results. There were significant differences for total laryngeal and cricotracheal scores (P<.001) between the groups with positive and negative results. Significant differences were as follows: in the larynx-large lingual tonsil (P<.001), postglottic edema (P<.001), arytenoid edema (P<.001), ventricle obliteration (P =.03), and true vocal fold edema (P = .001), and in the cricotracheal region-general edema and erythema (P =.003) and blunting of the carina (P<.001). Severe arytenoid edema, postglottic edema, or enlargement of lingual tonsil were pathognomonic of GERD. CONCLUSION: Many direct laryngoscopic and bronchoscopic findings correlate well with the diagnosis of GERD as determined by using other tests.

Improving the otolaryngology consultation service in a teaching hospital.

OBJECTIVE: To examine the type and quality of consultations requested from the otolaryngology service at a tertiary care hospital. STUDY DESIGN: Retrospective. METHOD: Review of written documentation of consultations over a 6-month period. RESULTS: One hundred eleven requests were received, and 107 written reports were made. Twenty services made requests. Thirty-two percent of requests had a legible requester or contact listed. Sixty-seven percent of requests stated why the patient was in hospital, and 85% stated the otolaryngological complaint. Thirty-two percent of requests made accurate reference to the otolaryngological history, and 6% recorded an ENT examination that was accurate. Seven percent of patients were intubated, and 16% had a tracheostomy prior to evaluation. Forty-eight percent of patients required flexible nasopharyngolaryngoscopy. Sixteen percent of patients required rhinoscopy, and 16% required tracheotomy. Twelve percent of patients needed audiograms, and small numbers of patients required biopsy, debridement of ears, ventilation tube insertion, nasal packing, or radiological studies. Reports were made by senior residents, and evidence that the case was discussed with or seen by an attending surgeon was present in 43% of reports. A diagnosis was stated in 85% of reports, and in 3% the diagnosis appeared to be inaccurate as compared with the history and physical examination recorded. A follow-up plan was stated in 70% of reports. CONCLUSIONS: There is a need to educate physicians about collegial communication regarding patients. This information can direct curriculum needed to prepare otolaryngology residents to provide a consultative service in a teaching hospital. This method of determining "true learning needs" can be used in other situations to improve resident training.

Complications in pediatric tracheostomies.

OBJECTIVE: To examine complications of pediatric tracheostomy. STUDY DESIGN: Retrospective. METHODS: Chart review of children undergoing tracheotomy or laryngeal diversion between 1990 and 1999. RESULTS: Charts of 142 children were examined. Average age was 2.64 years (standard deviation [SD], 4.73 y) at surgery. Duration of tracheostomy was 2.08 years (SD, 1.72 y) for those decannulated, 3.12 years (SD, 2.5 y) for those still with a stoma, and length of follow-up for the whole group was 4.14 years (SD, 8.69 y). At last follow-up, 56% had a tracheostomy, 29% had none, and 15% had died; one death was tracheostomy-related. Three percent had intraoperative complications, 11% had complications before the first tracheostomy tube change, and 63% had complications after the first tube change. Thirty-four percent had a trial of decannulation; 85% of these were successful. Fifty-four percent of those decannulated had complications. Number of complications was not related to duration of follow-up. In-hospital mortality was congruent to mortality predicted by PRISM (Pediatric Rate of Mortality) scores. CONCLUSIONS: Forty-three percent had serious complications involving loss of the tracheostomy airway (tube occlusion or accidental decannulation) or requiring a separate surgical procedure. Deaths directly attributable to tracheostomy complications occurred in 0.7%.

Incidence of reflux in young children undergoing adenoidectomy.

OBJECTIVE: To compare the incidence of gastroesophageal reflux disease (GERD) in children under 2 years of age who have symptomatic adenoid hypertrophy requiring surgical removal or who have otitis media with effusion requiring ventilation tube insertion without adenoidectomy. STUDY DESIGN: Retrospective chart review. SETTING: An academic pediatric otolaryngology unit. PATIENTS: All children under age 2 undergoing adenoidectomy (Ad group) between January 1998 and May 2000 were compared with children in the same age range having ventilation tube insertion without adenoidectomy (VT group). MAIN OUTCOME MEASURES: Whether a diagnosis of GERD was made, how it was made, GERD treatment, and resolution of symptoms were compared. RESULTS: There were 95 children in the Ad group and 99 in the VT group. GERD incidence was significantly higher in the Ad group where it was 42% versus 7% in the VT group (P < .001). In the Ad group, 88% of children age 1 or less had GERD, and 32% of those older than 1 had GERD diagnosed. In the VT group, 14% of patients age 1 or less and 2% of those older than 1 had a diagnosis of GERD. CONCLUSIONS: Children under age 2 with symptomatic adenoid enlargement requiring adenoidectomy have a significantly higher incidence of GERD than children in the same age group presenting with otitis media requiring ventilation tube insertion.

Success rates in paediatric tympanoplasty.

OBJECTIVE: To determine if the success of paediatric tympanoplasty is dependent on certain criteria, which are determinable prior to surgery. DESIGN: Retrospective chart review. SETTING: An academic paediatric otolaryngology department. PATIENTS: Seventy-seven patients who had undergone tympanoplasty with or without ossicular reconstruction, but without mastoidectomy, between April 1997 and May 1999. MAIN OUTCOME MEASURES: Status of the repaired tympanic membrane at last follow-up visit measured by otoscopic examination and with tympanometry. RESULTS: Eighty-nine tympanoplasties were performed during this period. The age range was 2.9 to 22 years. The success rate was 75% overall. For patients younger than 11 years (n = 43), the success rate was 82%, and for those 11 to 18 years (n = 44), it was 74%, which was not significantly different. In 18 patients 7.5 years or younger, the success rate was 79%. Perforation location, size, presence of myringosclerosis, status of the other ear or nose, history of the perforation, surgical approach, middle ear findings, canal packing, and gender were not shown to be significantly different between successful and unsuccessful tympanoplasty groups. CONCLUSION: These young patients had a good success rate post-tympanoplasty, which we believe reflects less severe disease. These results mitigate against delaying tympanoplasty in young children.

Ceruminolytic efficacy in adults versus children.

OBJECTIVES: An inexpensive, nontoxic ceruminolytic with reasonable efficacy that can be used by the patient or their caregivers at home could represent significant financial saving for patients and health care systems. The purpose of this study was to compare two simple ceruminolytics for in vitro efficacy. STUDY DESIGN: Randomized controlled trial. METHODS: Thirty-six children and 33 adults presenting to a community family practice clinic who had cerumen occluding at least one external auditory canal were randomly assigned to compare use of 10% aqueous sodium bicarbonate and 2.5% aqueous acetic acid as ceruminolytics in occlusive cerumen. RESULTS: We were unable to demonstrate a difference between in vivo efficacy of these two ceruminolytic solutions, but both solutions were significantly more efficacious in children than adults. CONCLUSIONS: There is a role for these ceruminolytics in children with occlusive cerumen, but adults would be better treated in another way.

Comparison of postoperative pain: tonsillectomy by blunt dissection or electrocautery dissection.

PURPOSE: To compare post-operative pain in children undergoing tonsillectomy by blunt dissection or electrocautery. METHOD: Thirty-six children between the ages of 5 and 15 years were recruited for the study. Tonsillectomy was done in a standardized fashion with uniform anaesthetic practices. Each child kept a pain diary for 10 days, recording pain twice daily on a Visual Analog Scale and Faces Pain Scale. Doses of analgesics were recorded. RESULTS: There were no statistically significant differences in the pain scores for the groups, although there was a trend toward more pain in the blunt dissection group. There were more complications in this group, and these children used significantly more doses of acetaminophen. Sources of bias are discussed. CONCLUSION: These results suggest a trend toward greater postoperative pain in children who have tonsillectomies by blunt dissection techniques.

Clinical presentation as a guide to the identification of GERD in children.

OBJECTIVE: to determine if there is a correlation between common otolaryngologic symptoms and presence of gastroesophageal reflux disease (GERD) in children. METHODS: charts of 295 children presenting with suspicion of GERD were reviewed for presenting symptoms including: (1) airway symptoms: stertor, stridor, frequent cough, recurrent croup, wheezing, nasal congestion, obstructive apnea, blue spells, hoarseness, throat clearing; (2) feeding symptoms: wet burps, globus sensation, frequent emesis, dysphagia, choking/gagging, sore throat, halitosis, food refusal, stomach aches, arching, drooling, chest pain, irritability, and failure to thrive. At least one positive test of barium esophagram, gastric scintiscan, pH probe or esophageal biopsy resulted in inclusion in the GERD positive group. RESULTS: 214 children had GERD diagnosed while 81 had no positive tests for GERD. Between the GERD positive and GERD negative groups, the significantly different symptoms were stertor (P=0.040), cyanotic spells (P=0.043), frequent emesis (P=0.007), failure to thrive (P=0.006), and choking/gagging (P=0.044). Three pooled variables were created: airway flow (stertor, stridor, cyanotic spells), airway irritation (frequent cough, recurrent croup, throat clearing), and feeding (dysphagia, failure to thrive, frequent emesis). GERD patients who were 2 years or less were compared to those older than 2 years and all three of these pooled variables were significantly different between these groups (P<0. 001). CONCLUSION: children who present with a certain constellation of airway or feeding symptoms are more likely to have a positive GERD test. Children 2 years old or less are more likely to present with airway symptoms or feeding difficulties while children older than 2 years are more likely to present with airway irritation.

Communication after laryngectomy: an assessment of quality of life.

The purpose of this study was to examine quality of life in laryngectomees using different methods of communication. A survey was mailed to all the living laryngectomees in Nova Scotia. Patients were asked to rate their ability to communicate in a number of common situations, to rate their difficulty with several communication problems, and to complete the EORTC QLQ-C30 quality-of-life assessment tool. Sixty-two patients responded (return rate of 84%); 57% were using electrolaryngeal speech, 19% esophageal speech, and 8.5% tracheoesophageal speech. These groups were comparable with respect to age, sex, first language, education level, and years since laryngectomy. There were very few differences between these groups in ability to communicate in social situations and no difference in overall quality of life as measured by these scales. The most commonly cited problem was difficulty being heard in a noisy environment. Despite the fact that tracheoesophageal speech is objectively most intelligible, there does not seem to be a measurable improvement in quality of life or ability to communicate in everyday situations over electrolaryngeal or esophageal speakers.

Correlation of findings on direct laryngoscopy and bronchoscopy with presence of extraesophageal reflux disease.

OBJECTIVE: To determine the correlation between findings at direct laryngoscopy and bronchoscopy and presence of extraesophageal reflux disease (EERD). STUDY DESIGN: Retrospective chart review METHODS: Operative notes of 155 children undergoing direct laryngoscopy and bronchoscopy between 1996 and 1999 for airway symptoms for whom there was a suspicion of EERD were examined. Gastroesophageal reflux disease (GERD) was considered present if at least one test was positive (including upper GI series, pH probe, gastric scintiscan, or esophageal biopsy). RESULTS: A total of 130 (84%) patients had GERD diagnosed. Ninety percent had at least one laryngotracheal abnormality: 83% had an abnormal larynx and 66% had an abnormal trachea. Laryngeal abnormalities in GERD included postglottic edema, 69%; arytenoid edema, 30%; large lingual tonsil, 16%; vocal fold edema, 12%; vocal fold nodule, 12%; ventricular obliteration, 5%; and hypopharyngeal cobblestoning, 3%. Tracheobronchial abnormalities in GERD included tracheal cobblestoning, 33%; blunting of carina, 12.5%; subglottic stenosis, 11%; increased secretions, 11%; and generalized edema or erythema, 5%. The best sensitivity or specificity was obtained by combining postglottic edema, arytenoid edema, and vocal fold edema, resulting in a sensitivity of 75% and a specificity of 67%. Positive predictive value was 100% for the combination of postglottic edema and any vocal fold or ventricular abnormality. CONCLUSION: Laryngoscopy and bronchoscopy can reveal findings with a high positive predictive value for the presence of GERD. Endoscopy of the upper airway in children with clinical signs and symptoms of EERD is a promising tool for diagnosis.

Assessment and management of idiopathic facial (Bell's) palsy: comparison of Nova Scotia family physicians and otolaryngologists.

Acute idiopathic facial paralysis, or Bell's palsy, is frequently encountered in clinical practice. The present study compares knowledge of Bell's palsy assessment and management between a group of family physicians and otolaryngologists practising in Nova Scotia. Respondents completed a questionnaire and statistical analyses were performed on selected data. There were similarities regarding Bell's palsy assessment and management, but there were notable differences in the ability to distinguish Bell's palsy on the basis of symptomatic complaints, specific counselling strategies, length of patient follow-up, and use of appropriate diagnostic tests. This needs assessment suggests several areas where a family physician continuing medical education program on management of acute facial paralysis may be beneficial.

Severe non-obstructive sleep disturbance as an initial presentation of gastroesophageal reflux disease.

A 2.5-year-old child presented with a sleep disturbance initially diagnosed as a behavioral problem. The child had several atypical symptoms of gastroesophageal reflux disease (GERD). The sleep disturbance resolved quickly after treatment of GERD. GERD is a disease with protean manifestations which is becoming of greater interest to the pediatric otolaryngologist. We discuss diagnosis of this entity.

Effect of steroids on posttonsillectomy pain in adults.

OBJECTIVE: To determine whether a single intraoperative dose of intravenous dexamethasone has an effect on pain after tonsillectomy. DESIGN: Double-blinded randomized controlled clinical trial. SUBJECTS: Thirty-four consecutive nonpediatric patients presenting for tonsillectomy. INTERVENTION: Patients scheduled for electrocautery tonsillectomy were randomized to receive either intravenous dexamethasone or placebo during surgery. Pain was measured twice daily for 10 days by means of a visual analog scale. RESULTS: There were no statistically significant differences between the groups, but the dexamethasone group had a trend to report less pain over the first several days. The dexamethasone group received less analgesic in the recovery room, but there were no differences between the groups in the 10 days afterward. CONCLUSIONS: There is evidence that a single dose of dexamethasone reduces pain after tonsillectomy to a small degree. A single dose was not associated with adverse effects, so the risk-benefit ratio may be favorable for this practice.

Comparison of computer-assisted instruction and seminar instruction to acquire psychomotor and cognitive knowledge of epistaxis management.

Epistaxis is a common problem faced by primary care physicians. Typically, first-hand experience with this problem is not obtained in medical school. A computer learning module was developed to address practical management of epistaxis. It was evaluated by use of third-year clerks and compared with an interactive seminar based on the same material. Fifty-eight students doing their required otolaryngology rotations were randomly separated into 3 groups: (1) doing a preinstruction test, (2) using the computer module, and (3) participating in a small-group seminar. All participants were tested with a short written test and a practical test that involved performing anterior nasal pack placement in a model patient. Percentage scores for the 2 groups were compared by use of t tests, and there was no significant difference between the written, practical, or combined scores at a level where P = 0.05. This study shows that basic patient management and a simple procedure can be taught as effectively with a computer module as with a small-group interactive seminar.

Needs assessment for an undergraduate otolaryngology curriculum.

A needs assessment was conducted to determine what family doctors need to know about otolaryngology. A survey was mailed to a group of community otolaryngologists and family doctors. They were asked to rate the importance of 46 otolaryngologic topics. A true needs assessment was carried out with a small group of family practice residents to examine which needs were perceived to be significantly different in importance between these 2 survey groups. A list of important topics was generated from the survey. There were many statistically significant differences between the survey groups, but only 2, vertigo and epistaxis, appeared to be potentially important. The family practice residents (n = 8) were asked to complete a short-answer test about epistaxis management and then to demonstrate placement of an anterior nasal pack. Despite having already faced this problem in 50% of cases, the residents had average scores of less than 30%, indicating a lack of knowledge in this area.
