Assessment of Pain and Analgesic Use in Children Following Otologic Surgery

Long-term outcomes following pediatric endoscopic titanium ossiculoplasty: A single-institution experience

INTRODUCTION

Endoscopic ossicular chain reconstruction (OCR) in adults has demonstrated equivalent outcomes to the traditional microscopic approach. Less data exist on endoscopic OCR outcomes in children, who have unique considerations including a smaller transcanal corridor and variable pathology. The purpose of this study was to investigate surgical and audiometric outcomes in children undergoing fully endoscopic and endoscopic-assisted OCR in both the short and long-term.

METHODS

Retrospective review of all children (<17 years) who underwent endoscopic OCR at one tertiary care center between 2017 and 2021. Children undergoing primary and revision endoscopic OCR with either partial (PORP) and total ossicular reconstruction prostheses (TORP) were included. Children undergoing surgery for juvenile otosclerosis or congenital stapes fixation, or any child receiving a stapes prosthesis were excluded. Primary outcome measures were post-operative change in 4 frequency (500 Hz, 1, 2, 4 KHz) air conduction pure tone average (AC PTA) and change in air-bone gap (ABG). Secondary measures included need for readmission and/or revision surgery, complication rate, and surgery duration.

RESULTS

Seventeen patients met inclusion criteria. Average age was 11.3 years (range, 5-17 years); 14 were male. A variety of fixed length, titanium total and partial prostheses were used. The most common prosthesis length was 2 mm (range 2-5 mm), and there were no intra- or perioperative complications. Mean long-term follow-up was 2.6 years. Most common pathology was congenital cholesteatoma (11/17, 64%), followed by chronic otitis media with tympanic membrane perforation (5/17, 29.4%), and extruded prosthesis (1/17, 5.9%). Intraoperatively, the most common finding was incus erosion (10/17, 58.8%), followed by malleus erosion (6/17, 35.3%), stapes erosion (4/17, 23.5%), and stapes absence (4/17, 23.5%). Eight children (47%) were reconstructed with PORPs, and 9 children (52.9%) were reconstructed with TORPs. Average ABG improved from 36.8 dB preoperatively to 19.9 dB postoperatively in the short-term and remained stable at 19.5 dB in the long-term. Average short-term ABG improvement was 4.2 dB for PORPs and 18 dB for TORPs. In the long-term, average ABG improved by 2.3 dB in PORPs and 13.4 dB in TORPs. PORPs had higher rates of ABG closure and lower AC PTAs than TORPs in the long-term.

DISCUSSION

Endoscopic ossiculoplasty is a viable option in children presenting with ossicular erosion from various causes. Audiometric improvement following endoscopic partial and total ossicular reconstruction remains stable over time, with a preference towards partial in the long-term, and mirrors published outcomes for microscopic surgery.

Pain management after microtia repair with costal cartilage: De-escalation and opioid use reduction

OBJECTIVE

Complex and invasive postoperative pain regimens for microtia reconstruction with costal cartilage are often utilized. These generate added costs and invasiveness. We evaluated the effectiveness of a de-escalated pain regimen without use of invasive interventions.

METHODS

Case series of patients who underwent stage 1 microtia reconstruction with a modified Nagata/Firmin technique from 2017 to 2020 at a pediatric tertiary care hospital. Patients received intraoperative bupivacaine intercostal blocks and scheduled acetaminophen. Adjunct medications administered and pain scores (Wong-Baker FACES and FLACC-Face, Legs, Activity, Cry, Consolability) at intervals 2-72 h postoperatively were recorded. Narcotic use, peak and median pain scores, and length of stay were compared with published values.

RESULTS

Twenty patients were included. Mean age of 12 and length of stay of 2.8 days. Average postoperative FACES scores between 0 and 72 h ranged between 0.7 and 4.0. The average peak pain score was 6.1 (±2.0). FLACC scores were low. Narcotics (0.59 ±0 .35 Morphine Milligram Equivalents/kg) were given to 17 patients. Compared to Shaffer et al. (paravertebral catheter-based infusion), total narcotics use (p = 0.03), peak pain (p = 0.0001), and length of stay (p = 0.001) were less. Compared to Woo et al. (intercostal catheter-based infusion), median pain scores at identical time intervals were lower (p = 0.04).

CONCLUSION

Intraoperative intercostal nerve blocks followed by scheduled, weight-based acetaminophen, adjunctive medications (ibuprofen and lidocaine patches), and rescue narcotics are effective in managing pain following microtia repair with autologous costal cartilage. It results in decreased narcotic usage, shorter length of stay, and lower pain scores compared to more complex regimens.

Opioid Prescribing Trends After Major Pediatric Ear Surgery: A 12-Year Analysis

OBJECTIVE

Postoperative opioid prescriptions tend to exceed children's analgesic needs, but awareness of the opioid epidemic may have driven changes in prescribing behaviors. This study evaluated opioid prescribing patterns after major pediatric ear surgery.

METHODS

This study reviewed all cases of tympanoplasty, tympanomastoidectomy, mastoidectomy, cochlear implantation, otoplasty, and aural atresia repair at a pediatric hospital during 2010-2021. Regressions were conducted to identify opioid prescribing trends over time. Potential covariates were assessed. Returns to the system were reviewed as a balancing measure.

RESULTS

Even without a targeted protocol, opioid prescribing declined significantly. After prescribing peaked in 2012-2013, significant negative trends yielded lower rates of opioid prescriptions, fewer doses per prescription, smaller patient-weight-standardized dose sizes, and less variability (all p < 0.001). In 2012, 96.1% of patients received opioid prescriptions; the rate fell to 13.5% by 2021. For patients ages, 0-6, the annual rate of opioid prescriptions dropped from a maximum of 96.3% in 2012 to 0.0% in 2021. The annual average supply of doses per prescription decreased by 68% between 2013 and 2021, reducing the total days' supply to an evidence-based 3.1 ± 1.6 days. Regressions did not detect changes in returns to the system. Pain-related returns were rare (0.9%) and did not vary by opioid prescriptions (p = 0.37). Prescribing trends were closely correlated with a tonsillectomy-focused protocol that our institution implemented in 2019.

CONCLUSION

Surgeon-driven opioid stewardship has improved with no resultant change in revisit rates. Procedure-specific quality improvement interventions may have broader off-target effects on prescribing behaviors.

Audiometric Outcomes Comparing Endoscopic Versus Microscopic Ossiculoplasty

OBJECTIVE

To assess endoscopic and microscopic ossiculoplasty audiometric outcomes.

STUDY DESIGN

Retrospective review.

SETTING

Tertiary academic center.

PATIENTS

Adult patients who underwent ossiculoplasty with either partial ossicular replacement prosthesis (PORP) or total ossicular replacement prosthesis (TORP) from 2010 to 2019 with at least 1 year of audiometric follow-up were included.

INTERVENTIONS

Endoscopic or microscopic ossiculoplasty.

MAIN OUTCOME MEASURES

Postoperative air-bone gap (ABG) after at least 1 year.

RESULTS

A total of 198 patients, 53.5% female, and a median age of 47.5 years, met inclusion criteria. 64.1% of patients were reconstructed with a PORP, and 31.8% were reconstructed using an endoscopic approach. The median audiometric follow-up was 27 months. The median postoperative ABG was 16.9 dB overall, 15.6 dB for PORP reconstruction, and 19.4 dB for TORP reconstruction (PORP versus TORP, p = 0.002). For TORP reconstructions, the median ABG for both endoscopic and microscopic TORP was 19.4 dB (p = 0.92). For PORP reconstructions, the median ABG for endoscopic PORP was 12.3 dB compared with 16.3 dB for microscopic PORP (p = 0.02). Using multivariate linear regression to predict postoperative PORP ABG, and controlling for age, prior ossiculoplasty, middle ear mucosal disease (granulation, fibrosis, polyposis), middle ear atelectasis, myringitis, contralateral middle ear disease, and use of byte prostheses, endoscopic PORP reconstruction was associated with improvement in ABG over the microscopic approach by 4.4 dB (p = 0.04).

CONCLUSIONS

For PORP ossiculoplasty procedures, endoscopic ossiculoplasty is associated with improved postoperative ABG compared with microscopic ossiculoplasty.

Postoperative pain after transcanal endoscopic ear surgery: A systematic literature review

OBJECTIVE

Transcanal endoscopic ear surgery is hypothesized to result in less postoperative pain when compared to nonendoscopic techniques due to its minimally invasive nature. In this systematic literature review, we aim to summarize and evaluate the evidence surrounding postoperative pain control and analgesic utilization after transcanal endoscopic ear surgery.

DATABASES REVIEWED

PubMed, EMBASE, and Cochrane.

METHODS

A systematic literature search was performed using standardized methodology. Computerized and manual searches were performed to identify studies that evaluated postoperative pain outcomes following endoscopic ear surgery. Only studies that met predetermined criteria were selected and evaluated for quality and bias. Extracted data included demographics, pain scores, analgesic administered as well as the diagnosis and type of surgery undertaken. Exclusion criteria included letters/commentaries and reviews, lack of pain outcome data and studies not concerning endoscopic ear surgery.

RESULTS

The systematic literature review included 24 studies. Seven were RCTs, 10 were prospective and 7 were retrospective observational studies. A total of 1859 patients were evaluated for surgical approach and postoperative pain levels and analgesic use. Due to the lack of sufficient reporting of the data, a meta-analysis was not applicable. In the qualitative synthesis for the primary outcome, weighted pooled analysis showed that there was a slight reduction in postoperative pain after transcanal endoscopic ear surgery. Based on the Cochrane risk of bias tool, the quality for the finding is low.

CONCLUSION

There is a small reduction in postoperative pain after transcanal endoscopic ear surgery when compared to nonendoscopic approaches, however, the clinical significance of this reduction is unclear. The evidence was from studies of only low to moderate quality.
