The utility of a “second look” debridement following endonasal skull base surgery in the pediatric population

Background: Sinonasal debridement is typically performed in the weeks following endonasal skull base surgery (ESBS). In the pediatric population, this second look procedure may require general anesthesia, however there is currently little evidence assessing the benefit of this practice. Methods: This was a multicenter retrospective study of pediatric patients (age <18 years) undergoing a planned second look debridement under general anesthesia following ESBS. Intraoperative findings, interventions performed, and perioperative complications were reviewed. Multivariate regression analysis was performed to identify associations between intraoperative findings and clinical factors. Results: We reviewed 69 cases of second look debridements (age mean 8.6 ±4.2 years, range 2-18 years), occurring a mean of 18.3 ±10.3 days following ESBS. All abnormal findings were noted in patients age ≤12 years. Synechiae were noted in 8.7% of cases, bacterial rhinosinusitis in 2.9%, and failed reconstruction with CSF leak in 4.5% (2 cases of flap malposition, 1 case of flap necrosis). All failed reconstructions were noted following expanded endonasal cases for craniopharyngioma, and in each case a revision reconstruction was performed during the second look surgery. Synechiae were not significantly associated with younger age, revision cases, or cases with reconstructive flaps. There were no perioperative complications. Conclusion: Second look debridement under general anesthesia may be useful in the identification and intervention of sinonasal pathology following endoscopic skull base surgery, particularly in children ≤12 years old or those with pedicled flap reconstructions. Larger controlled studies are warranted to validate this practice and refine indications and timing of this second procedure.

Trends and Healthcare Use Following Different Cholesteatoma Surgery Types in a National Cohort, 2003-2019

OBJECTIVE

To describe national trends in cholesteatoma management.

STUDY DESIGN AND SETTING

Retrospective analysis Optum Clinformatics® Database from 2003 to 2019.

PATIENTS

16,179 unique adult and pediatric patients who received cholesteatoma surgery.

INTERVENTIONS AND MAIN OUTCOME MEASURES

Patients were categorized into three groups by initial surgical modality: canal wall down (CWD), canal wall up (CWU), and tympanoplasty without mastoidectomy (TnoM). Three major comparisons between groups were performed: 1) temporal trends, 2) clinical and sociodemographic determinants, and 3) healthcare use in terms of total costs and incidence of postoperative imaging and subsequent surgery.

RESULTS

Overall, 23.2% received initial CWD surgery, 44.3% CWU, and 32.5% TnoM. 1) The incidence of initial CWD surgery decreased (odds ratios [OR] = 0.98, 95% confidence intervals [CI] [0.97,0.99]), while CWU increased (OR = 1.02, 95% CI [1.01,1.03]), and TnoM remained stable over the study period (OR = 0.99, 95% CI [0.98,1.00]). 2) Relative to CWU, TnoM surgery was less likely in adults, patients with prior complications, and non-White patients, while being more likely in patients with higher household income. CWD was more likely than CWU in adults, patients with prior complications, and non-White patients, while income had no effect. 3) Postoperative costs for CWU and CWD were similar. In 2 years following initial surgery, postoperative imaging and/or subsequent surgery was performed in 45.48% of CWD, 57.42% of CWU, and 41.62% of TnoM patients.

CONCLUSIONS

Incidence of initial CWD surgery decreased and social disparities in cholesteatoma management were observed. Postoperative imaging or second-look surgery were performed in less than 60% of patients with initial CWU surgery and over 40% of patients with initial CWD.

Post-Tonsillectomy Ibuprofen: Is There a Dose-Dependent Bleeding Risk?

OBJECTIVES/HYPOTHESIS

Post-tonsillectomy hemorrhage (PTH) is a potentially life-threatening complication. A recent meta-analysis suggests that ibuprofen may increase the risk of PTH. The aims of this study were to 1) re-evaluate the effect of ibuprofen on PTH given additional recent evidence and 2) to evaluate a potential dose effect of ibuprofen.

STUDY DESIGN

Meta-analysis and meta-regression; single-institution retrospective review.

METHODS

We conducted a systematic review of the literature and a meta-analysis of 12 studies comparing postoperative ibuprofen analgesia to non-nonsteroidal anti-inflammatory drug (NSAID) controls. Next, we performed a meta-regression analysis to assess for an effect of dose, if any, on rates of PTH. Five studies specifying a dose of 5 mg/kg (828 patients, 1,411 controls) and 7 studies using 10 mg/kg (5,633 patients, 7,656 controls) were included. We then conducted a novel single-institution, retrospective review of data for 1,046 patients prescribed intermediate-dose 7.5 mg/kg ibuprofen.

RESULTS

Ibuprofen was not associated with an increased rate of PTH (log odds ratio [OR], 0.21; 95% confidence interval [CI] -0.15, 0.57). Meta-regression showed that ibuprofen dose (5 and 10 mg/kg) did not have a statistically significant effect on PTH (OR, 1.32; 95% CI 0.30, 5.84). Uncontrolled, aggregate rates of PTH across all studies were 2.29% (N = 828) for 5 mg/kg and 4.65% (N = 5,633) for 10 mg/kg dosing. The rate of secondary hemorrhage in patients prescribed 7.5 mg/kg ibuprofen was 3.10% (N = 1,046).

CONCLUSION

We found no statistically significant increased risk of PTH when ibuprofen is prescribed at the low or high range of commonly used clinical dosages, compared to a non-ibuprofen regimen. Further studies with less heterogeneity are needed to determine if there is a clinically relevant dose-dependent difference in PTH with ibuprofen.

Oral Corticosteroids Following Endoscopic Sinus Surgery for Chronic Rhinosinusitis Without Nasal Polyposis: A Randomized Clinical Trial

Importance

Although oral corticosteroids are commonly prescribed following endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS) without nasal polyposis, there are little data to suggest that this is a beneficial practice.

Objective

To assess the efficacy of oral corticosteroids following ESS in CRS without polyps.

Design, Setting, and Participants

This prospective double-blinded, placebo-controlled, randomized noninferiority clinical trial conducted in a single academic tertiary rhinology practice included adults with CRS without polyps undergoing ESS. Of 81 patients recruited, 72 completed the study.

Interventions

Patients were randomized into 2 treatment groups: a 12-day postoperative taper of oral prednisone vs matched placebo tablets. All study patients also received a uniform 2-week postoperative regimen of oral antibiotics, fluticasone nasal spray, and saline rinses.

Main Outcomes and Measures

The primary outcome measures were Sinonasal Outcome Test-22 (SNOT-22) scores and Lund-Kennedy endoscopy scores, collected preoperatively and postoperatively at 1 week, 1 month, 3 months, and 6 months. Scores were compared between treatment groups at each time point using longitudinal difference between treatment groups and analyzed using 2-way, repeated measures analysis of variance. Secondary outcome measures included treatment-related adverse effects.

Results

Overall, 72 patients (mean [SD] age, 49.4 [14.9] years; 36 men, 36 women) completed the study, with 33 in the prednisone arm and 39 in the placebo arm. When comparing longitudinal differences between treatment groups, there was no clinically meaningful difference observed in SNOT-22 total (F[4254] = 1.71, η2 = 0.01 [95% CI, 0.00-0.05]) or Lund-Kennedy scores (F[4247] = 1.23, η2 = 0.02 [95% CI, 0.00-0.50]). In SNOT-22 subdomain analyses, there was no clinically meaningful difference between treatment groups for rhinologic, extranasal rhinologic, ear/facial, or sleep subdomains. However, the prednisone group had worse longitudinal scores for psychological dysfunction compared with the placebo group (F[4254] = 3.18, η2 = 0.05 [95% CI, 0.02-0.09]). Reported adverse effects were similar between the 2 treatment groups.

Conclusions and Relevance

In this randomized clinical trial of patients with CRS without polyps, oral prednisone following ESS conferred no additional benefit over placebo in terms of SNOT-22 total scores, SNOT-22 rhinologic subscores, or Lund-Kennedy endoscopy scores up to 6 months after surgery. Patients receiving prednisone, however, did demonstrate worse SNOT-22 psychologic subdomain scores. These results suggest that the risks of oral corticosteroids may outweigh the benefits; thus use of oral corticosteroids after ESS for CRS without polyps should be carefully considered.

Impact of lymph node sampling on survival in cN0 major salivary gland adenoid cystic carcinoma

BACKGROUND

The role of elective neck dissection in the management of major salivary gland adenoid cystic carcinoma is unclear.

METHODS

Data were retrospectively extracted from the National Cancer Center Database. The study cohort included 1504 patients with adenoid cystic carcinoma of major salivary glands with clinical N0 necks who were treated with surgery between 2004 and 2014. The cohort was divided into four groups based on number of lymph nodes (LNs) examined on pathology: 0, 1-8, 9-17, and ≥18 LNs.

RESULTS

The rate of occult nodal metastasis was 9.0%. Number of LNs removed was not associated with survival (Reference, 0 LNs; HR = 0.98, 95% CI 0.73-1.32 for 1-8 LNs; HR = 1.22, 95% CI 0.80-1.88 for 9-17 LNs; HR = 0.94, 95% CI 0.61-1.46 for ≥18 LNs) after adjusting for important covariates.

CONCLUSIONS

LN sampling is not associated with survival in cN0 major salivary gland ACC.

Hearing Aid Use is Associated with Better Mini-Mental State Exam Performance

OBJECTIVE

Hearing loss is associated with cognitive decline in the elderly. However, it is unknown if the use of hearing aids (HAs) is associated with enhanced cognitive function.

METHODS

In a cross-sectional study at an academic medical center, participants underwent audiometric evaluation, the Mini-Mental State Exam (MMSE), and the Trail Making Test, Part B (TMT-B). The impact of use versus disuse of HAs was assessed. Performance on cognitive tests was then compared with unaided hearing levels.

RESULTS

HA users performed better on the MMSE (1.9 points; rank-sum, p = 0.008) despite having worse hearing at both high frequencies (15.3-dB hearing level; t test, p < 0.001) and low frequencies (15.7-dB hearing level; t test p < 0.001). HA use had no effect TMT-B performance. Better performance on the MMSE was correlated with both low frequency (ρ = -0.28, p = 0.021) and high frequency (ρ = -0.21, p = 0.038) hearing level, but there was no correlation between performance on the TMT-B and hearing at any frequency.

CONCLUSION

Despite having poorer hearing, HA users performed better on the MMSE. Better performance on cognitive tests with auditory stimuli (MMSE) but not visual stimuli (TMT-B) suggests that hearing loss is associated with sensory-specific cognitive decline rather than global cognitive impairment. Because hearing loss is nearly universal in those older than 80 years, HAs should be strongly recommended to minimize cognitive impairment in the elderly.

Effects of cigarette smoking and smoking cessation on plasma constituents and enzyme activities related to oxidative stress

In order to study effects of cigarette smoking and smoking cessation on plasma constituents and enzyme activities related to oxidative stress, 1255 smokers and 524 healthy non-smokers were investigated in terms of plasma levels of lipoperoxides (LPO), nitric oxide (NO), vitamin C (VC), vitamin E (VE) and beta-carotene (beta-CAR). Additionally, erythrocytes were examined to determine the level of LPO, the activities of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px). The results showed that, when compared with the average values of the non-smoker group, the average plasma values of LPO, NO and the average erythrocyte value of LPO in the smoker group were significantly increased (P < 0. 001), while the average plasma values of VC, VE, beta-CAR, and the average erythrocyte activities of SOD, CAT, GSH-Px were significantly decreased (P < 0.001). A linear regression and correlation analysis for 65 male smokers who were all 40 years old showed that with longer smoking duration and greater daily smoking quantity, the plasma values of LPO, NO and the erythrocyte value of LPO were elevated, while the plasma values of VC, VE, beta-CAR and erythrocyte values of SOD, CAT, GSH-Px were decreased. In a group of 73 smokers who stopped smoking completely for six months, the average plasma values of LPO, NO and the average erythrocyte value of LPO decreased, although they were still significantly higher than those in the matched non-smoker group (P < 0.05). Additionally, the average plasma values of VC, VE, beta-CAR and the average erythrocyte values of SOD, CAT, GSH-Px increased, although they were still significantly lower than those in the matched non-smoker group (P < 0.05). However, after smoking cessation for one year the above average values were not significantly different from those in the matched non-smoker group (P > 0.05). This finding indicates that the markedly increased oxidative stress in smokers might gradually return to normal but only after a long period of smoking cessation. In conclusion, in the bodies of smokers a series of free radical chain reactions were gravely aggravated, the dynamic balance between oxidation and antioxidation was seriously disrupted, and oxidative stress was clearly exacerbated, which is closely related to many disorders or diseases in smokers. The present study underscored the need, urgency and importance of complete smoking cessation.
