Improving applicant selection: identifying qualities of the unsuccessful otolaryngology resident.

OBJECTIVES/HYPOTHESIS: To identify the prevalence and management of problematic residents. Additionally, we hope to identify the factors associated with successful remediation of unsuccessful otolaryngology residents. STUDY DESIGN: Self-reported Internet and paper-based survey. METHODS: An anonymous survey was distributed to 152 current and former program directors (PDs) in 2012. The factors associated with unsuccessful otolaryngology residents and those associated with the successful remediation of problematic residents were investigated. An unsuccessful resident is defined as one who quit or was removed from the program for any reason, or one whose actions resulted in criminal action or citation against their medical license after graduation from residency. Remediation is defined as an individualized program implemented to correct documented weaknesses. RESULTS: The overall response rate was 26% (40 PDs). Seventy-three unsuccessful or problematic residents were identified. Sixty-six problematic or unsuccessful residents were identified during residency, with 58 of 66 (88%) undergoing remediation. Thirty-one (47%) residents did not graduate. The most commonly identified factors of an unsuccessful resident were: change in specialty (21.5%), interpersonal and communication skills with health professionals (13.9%), and clinical judgment (10.1%). Characteristics of those residents who underwent successful remediation include: poor performance on in-training examination (17%, P < .01) and inefficient use of time (11.4%, P = .02). CONCLUSIONS: A large proportion of otolaryngology PDs in this sample identified at least one unsuccessful resident. Improved methods of applicant screening may assist in optimizing otolaryngology resident selection.

Section for Residents and Fellows-in-Training Leaders: Where Are They Now?

The purpose of this study was to examine the experiences of prior governing council (GC) members of the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) Section for Residents and Fellows-in-Training (SRF) and assess the impact of early Academy involvement. A survey was conducted via email on all prior AAO-HNS SRF GC members. The AAO-HNS SRF has elected 52 GC members since its 2003 inception. Each member served an average of 1.5 year-long terms. The mean time since completion of training is 4.1 years. A subspecialty fellowship was pursued in 86%. Fifty-seven percent practice in academic settings, with 3 members advancing to subspecialty division director within their department. More than half (58%) have served on an AAO-HNS committee, and most are frequent attendees of the annual meeting. All prior members felt involvement in the SRF GC was beneficial, enabling them to gain leadership skills and deeper understanding of the specialty.

Section for residents and fellows-in-training survey results.

OBJECTIVES: (1) To present data from the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) Section for Residents and Fellows-in-Training (SRF) annual survey from 2002 to 2011. (2) To compare and analyze trends in resident demographics, residency experiences, and post-training career choices. STUDY DESIGN: Review of cross-sectional survey data. SETTING: Residents and Fellows registered as Members-in-Training through AAO-HNS. METHODS: A review of data from surveys distributed between 2002 and 2011 was conducted. Respondent demographic data including age, postgraduate year, gender, and geographic distribution were analyzed. Responses about training experiences, fellowship selection, debt burden, and post-training practice choice were studied in order to elicit trends. RESULTS: Respondents have consistently rated otolaryngology, anesthesia, and trauma/critical care as the most important intern rotations for otolaryngology residents. Each year, approximately 70% of respondents have reported interest in pursuing a fellowship. Pediatric otolaryngology fellowship is now the most popular fellowship among respondents. There has been a recent increase in the percentage of respondents who are interested in pursuing a career in academics. Location, family, and lifestyle have consistently been the most important factors in determining choice of practice. Respondents have reported increasing levels of educational debt. CONCLUSION: The AAO-HNS SRF survey collects important data regarding resident/fellow training. Several factors limit the generalizability of these results. Despite its limitations, these unique data provide valuable information for continual evaluation and improvement of physician training in the specialty.

Effect of continuous positive airway pressure on C-reactive protein levels in sleep apnea: a meta-analysis.

OBJECTIVE: Evaluate the effects of continuous positive airway pressure (CPAP) on C-reactive protein (CRP) levels, reported either as a primary or secondary end point among patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) based on a meta-analysis of published studies. DATA SOURCES: English-language searches of PubMed, Ovid, and the Cochrane databases were completed. Reference sections of identified studies were also examined for additional relevant articles to review. REVIEW METHODS: Studies of adult patients with OSAHS who reported pre- and post-CPAP treatment CRP were reviewed and analyzed. Two independent reviewers extracted data from 10 peer-reviewed studies, which were combined using a random effects meta-analysis model. RESULTS: The CPAP treatment was found to lead to a significant reduction in CRP levels (17.8%, P = .002). This corresponds to an effect size of -0.485 (-0.731, -0.240). Sensitivity analysis was done to determine the impact of study design. Both case-control studies and case-series studies yielded a significant effect. Sensitivity analysis also yielded a significant effect for studies with average body mass index <30, studies where CPAP was employed over automatic positive airway pressure, and studies treating patients ≤ 3 months. Analysis of publication bias, however, revealed a likelihood of "missing" studies. CONCLUSION: Although there is a significant lack of high-quality studies addressing this question, this analysis suggests that treatment with CPAP leads to a statistically significant reduction in CRP levels. However, the mean pre- and posttreatment CRP levels observed are considered "high risk" for cardiovascular morbidity. The clinical significance of this finding as it relates to cardiovascular risk reduction and the relationship between CRP and OSAHS requires further study.

Modified adenotonsillectomy to improve cure rates for pediatric obstructive sleep apnea: a randomized controlled trial.

OBJECTIVE: To compare the efficacy of adenotonsillectomy (T&A) with and without pharyngoplasty (tonsillar pillar closure) in the treatment of pediatric obstructive sleep apnea-hypopnea syndrome (OSAHS). STUDY DESIGN: Randomized single-blind controlled study. SETTING: Tertiary care center. SUBJECTS AND METHODS: Sixty pediatric patients with a clinical diagnosis of OSAHS presenting between January 2009 and December 2010 were enrolled and randomized to undergo either standard T&A (n = 30) or T&A with pharyngoplasty (n = 30). Surgical cure was defined as apnea-hypopnea index (AHI) <5 plus OSA-18 health-related quality-of-life (HRQL) score <60. Other outcomes included postsurgical AHI and minimum oxygen saturation (SpO(2)) improvement, changes in OSA-18 scores at 1 month, and postsurgical days to resume normal diet and activity. RESULTS: Three patients from each group did not undergo surgery. Of the 54 patients treated, 8 from the pharyngoplasty group and 2 from the standard group were lost to follow-up. Intention-to-treat analysis revealed no difference in cure rate between groups (standard 60%, pharyngoplasty 56.6%, P = .793). Limiting analysis to those patients with complete data, a higher, but not significantly increased, cure rate with pharyngoplasty was noted (72% vs 89.5%, P = .155). Greater OSA-18 improvement (P = .036) and greater (although nonsignificant) AHI improvement and earlier return to normal function were noted with pharyngoplasty. CONCLUSION: The addition of pharyngoplasty to traditional adenotonsillectomy did not significantly improve OSAHS cure rates as measured by sleep testing and HRQL, although a nonsignificant increase in cure rate was observed in those who completed the study protocol. An unexpectedly high rate of patient dropout rendered the study statistically underpowered and therefore inconclusive.

Compliance and efficacy of titratable thermoplastic versus custom mandibular advancement devices.

OBJECTIVE: To share our experiences treating patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) with titratable thermoplastic (TPD) and custom-made mandibular advancement devices (MAD) and to compare these devices in terms of objective improvement and cure and treatment success (improvement/cure plus adherence at 6 months). STUDY DESIGN: Case series with planned data collection. SETTING: Tertiary care center. SUBJECTS AND METHODS: Patients with OSAHS who failed or refused both continuous positive airway pressure (CPAP) and surgery had a titratable oral appliance fitted. Patients were offered an office-fitted TPD or a custom-made dentist-fitted device. Assessment included pretreatment and appliance-titration polysomnography (PSG). Improvement was defined as ≥ 50% apnea-hypopnea index (AHI) reduction plus posttreatment AHI <20, and cure was defined as AHI <5. Patients were contacted at 1 and 6 months regarding treatment adherence. RESULTS: A total of 180 patients (123 TPD, 57 custom) with complete PSG data were reviewed. Improvement/cure were significantly better with the custom device overall (91.2%/71.9% vs 77.2%/52.0%, P = .024/.012). Adherence data at 1 and 6 months were obtained from 128/180 and 119/180 patients, respectively. Using an intention-to-treat analysis, those lost to follow-up were considered nonadherent. Adherence at 1/6 months was 64.9%/50.9% for custom versus 53.7%/32.5% for TPD (P = .156/.018), yielding treatment success rates (with initial improvement/cure) of 49.1%/40.4% for custom versus 27.6%/17.1% for TPD (P = .005/<.001) at 6 months. CONCLUSION: Custom-fit devices achieve higher rates of objective improvement and cure of OSAHS than TPD at the time of titration-PSG. TPDs have a high acceptance rate, low cost, and reasonable initial improvement and cure rates of 77.2% and 52.0%, respectively, but significantly poorer 6-month compliance.

The value of routine pH monitoring in the diagnosis and treatment of laryngopharyngeal reflux.

OBJECTIVE: To assess the need for pH testing in diagnosing laryngopharyngeal reflux (LPR). STUDY DESIGN: Case series with planned data collection. SETTING: Tertiary care center. SUBJECTS AND METHODS: On the basis of symptoms and/or abnormal endoscopic findings, more than 500 patients underwent 24-hour pharyngeal pH testing at a single center (using the Dx-pH probe) between January 2009 and June 2011. A total of 163 patients not on proton-pump inhibitors at the time of study and with complete data available for analysis (pH results, body mass index, smoking status, pretest reflux symptom index) were divided into 2 groups by positive (n = 70) and negative (n = 93) Ryan Score. The Reflux Symptom Index (RSI) was compared between groups and assessed overall against Ryan Score parameters at different pH thresholds. The diagnostic utility of an RSI ≥ 13 for prediction of Ryan Score was assessed. RESULTS: No significant difference in RSI was seen between Ryan-positive (17.50 ± 11.47) and Ryan-negative (14.95 ± 11.43) patients (P = .161). Overall, RSI correlated poorly with percentage time spent below pH thresholds 6.5, 6.0, 5.5, and 5.0 and upright and supine Ryan parameters at these thresholds (as determined by linear regression analysis). The sensitivity, specificity, positive predictive value, and negative predictive value of RSI ≥ 13 for Ryan positivity were 55.7%, 47.3%, 44.3%, and 58.7%, respectively. CONCLUSION: Our findings show that in our population of otolaryngology patients, the diagnosis of LPR cannot be reliably made on the basis of symptoms alone. Diagnosis, and in particular treatment decisions, should ideally be made on the basis of a combination of symptoms, signs, and confirmatory testing.

Transoral robotic glossectomy for the treatment of obstructive sleep apnea-hypopnea syndrome.

OBJECTIVE: In previous reports of transoral robotic surgery (TORS) for the treatment of obstructive sleep apnea-hypopnea syndrome (OSAHS), patients underwent routine tracheotomy. We aim to assess the feasibility of performing robotically assisted partial glossectomy without tracheotomy and to assess efficacy by comparing OSAHS outcomes with those of established techniques. STUDY DESIGN: Historical cohort study with planned data collection. SETTING: Tertiary care center. SUBJECTS AND METHODS: Forty consecutive patients underwent TORS for OSAHS between October 2010 and June 2011 and were followed up with regard to complications, morbidity, and subjective and objective outcomes. Data from 27 of these patients who underwent concomitant z-palatoplasty with 6-month follow-up were compared with those of 2 matched cohorts of patients, who underwent either radiofrequency (radiofrequency base-of-tongue reduction [RFBOT]) or coblation (submucosal minimally invasive lingual excision [SMILE]) reduction of the tongue base and z-palatoplasty. RESULTS: No major bleeding or airway complications were observed. Postoperative pain and length of admission were similar between groups. All groups saw Epworth score and snore score improvement. Patients undergoing robot-assisted surgery took longer than their SMILE and RFBOT counterparts to tolerate normal diet and longer than RFBOT patients to resume normal activity. Apnea hypopnea index (AHI) reduction averaged 60.5% ± 24.9% for TORS versus 37.0% ± 51.6% (P = .042) and 32.0% ± 43.3% (P = .012) for SMILE and RFBOT, respectively. Only the robotic group achieved statistically significant improvement in minimum oxygen saturation. Surgical cure rate for TORS (66.7%) was significant compared with RFBOT (20.8%, P = .001) but not compared with SMILE (45.5%, P = .135). CONCLUSION: Robotically assisted partial glossectomy feasibly can be performed without the need for tracheotomy. This technique resulted in greater AHI reduction but increased morbidity compared with the other techniques studied.

Impact of nasal obstruction on obstructive sleep apnea.

OBJECTIVES: The purpose of this study was to investigate the relationship between nasal obstruction and sleep-disordered breathing. The effect of postoperative nasal packing on sleep parameters was compared between patients with mild obstructive sleep apnea (OSA) and those with moderate/severe OSA. STUDY DESIGN: A prospective, nonrandomized controlled study. SETTING: Tertiary care center. SUBJECTS AND METHODS: Participants were recruited among adult patients with a history of snoring scheduled to undergo nasal surgery from November 2009 to February 2010. All subjects underwent polysomnogram (PSG) testing within 30 days prior to surgery. Patients underwent nasal surgery and received postoperative nasal packing, and a PSG was repeated on the first postoperative night with nasal packing in place. Outcome measures included a change in respiratory disturbance index (RDI), minimum oxygen saturation, oxygen desaturation index (ODI), and duration of snoring. RESULTS: Forty-nine patients were included in the study. Patients were stratified into 2 groups: those with RDI ≥15 (n = 23) and those with RDI <15 (n = 26). Nasal packing was found to significantly increase RDI (5.2 ± 4.0 vs 10.4 ± 10.0; P = .0001), duration of snoring (86.5% ± 13.1% vs 79.3% ± 15.3%; P = .008), and ODI (7.6 ± 7.1 vs 9.9 ± 7.4; P = .001) in patients with mild OSA but not in patients with moderate/severe OSA. Mean minimum arterial oxygen saturation was unchanged in both groups. CONCLUSION: Postoperative nasal packing aggravated measures of OSA in patients with mild OSA but not in patients with moderate/severe OSA.

Impact of pH monitoring on laryngopharyngeal reflux treatment: improved compliance and symptom resolution.

OBJECTIVES: Treatment of laryngopharyngeal reflux (LPR) often suffers from poor patient compliance and hence poor symptom improvement. The aim of this study was to determine whether 24-hour oropharyngeal pH monitoring was associated with higher rates of treatment compliance and symptom improvement compared with empirical treatment for LPR. STUDY DESIGN: Retrospective, case-control study. SETTING: Tertiary care center. SUBJECTS AND METHODS: Charts were reviewed from 170 consecutive adult patients diagnosed with LPR from January 2008 to March 2010. After clinical diagnosis, all patients were offered the option of empiric treatment with a proton pump inhibitor versus treatment based on a 24-hour oropharyngeal pH study using the Dx-pH system (Restech, San Diego, California). Treatment compliance and pretreatment and posttreatment reflux symptom index (RSI) scores were compared for the 2 groups. Only consecutive patients with complete data were included. RESULTS: One-hundred and seventy patients were included in 2 groups. Group I consisted of 73 patients who underwent pH monitoring. Group II consisted of 70 patients treated empirically. Compliance with medication therapy (68.5% vs 50.0%, P = .019) and lifestyle modification (82.2 vs 25.7%, P = .0001) were greater among patients in group I. Symptom improvement was greater among patients in group I following treatment compared with patients in group II, with a significantly greater reduction in RSI (36.6% vs 24.4%, P = .023). CONCLUSION: Among our patient population, treatment of LPR based on pH monitoring resulted in greater compliance, as well as greater symptom improvement, compared with empirical therapy alone.

Silencing the Kir4.1 potassium channel subunit in satellite glial cells of the rat trigeminal ganglion results in pain-like behavior in the absence of nerve injury.

Growing evidence suggests that changes in the ion buffering capacity of glial cells can give rise to neuropathic pain. In the CNS, potassium ion (K+) buffering is dependent on the glia-specific inward rectifying K+ channel Kir4.1. We recently reported that the satellite glial cells that surround primary sensory neurons located in sensory ganglia of the peripheral nervous system also express Kir4.1, whereas the neurons do not. In the present study, we show that, in the rat trigeminal ganglion, the location of the primary sensory neurons for face sensation, specific silencing of Kir4.1 using RNA interference leads to spontaneous and evoked facial pain-like behavior in freely moving rats. We also show that Kir4.1 in the trigeminal ganglion is reduced after chronic constriction injury of the infraorbital nerve. These findings suggests that neuropathic pain can result from a change in expression of a single K+ channel in peripheral glial cells, raising the possibility of targeting Kir4.1 to treat pain in general and particularly neuropathic pain that occurs in the absence of nerve injury.
