How Expensive is ENT Surgeons' Involvement in Retrosigmoid Craniotomies? A Time-Driven Activity-Based Cost Analysis

This study aims to examine the impact of ear, nose, and throat (ENT) surgeons' involvement on intraoperative costs and operating room (OR) times for retrosigmoid craniotomies using time-driven activity-based costing (TDABC).

✦ Clinical Takeaway ✦

No actionable change for most audiologists; findings are relevant to ENT surgeons and hospital administrators making decisions about surgical team composition for skull-base procedures.

✦ Why It Matters ✦

As healthcare systems face cost pressures, quantifying the value of ENT involvement in skull-base surgeries helps justify or scrutinize multidisciplinary team costs — indirectly affecting referral pathways for audiology patients with acoustic neuromas or similar tumors.

✦ Key Points ✦
