Piezosurgery versus microdrill in intact canal wall mastoidectomy

Area of Science:

• Otolaryngology
• Surgical Technology
• Neurosurgery

Background:

• Piezosurgery utilizes controlled microvibrations for precise bone cutting.
• Traditional mastoidectomy often employs microdrills for bone removal.
• Evaluating novel surgical tools is crucial for improving patient outcomes.

Purpose of the Study:

• To assess the efficacy and safety of piezosurgery in intact canal wall mastoidectomy.
• To compare piezosurgery outcomes with the traditional microdrill method.
• To evaluate the impact on operative time, hospital stay, and audiological function.

Main Methods:

• A non-randomized controlled trial involving 60 patients undergoing mastoidectomy.
• 30 patients were treated with a piezoelectric device, and 30 with a microdrill.
• Comprehensive audiological and clinical assessments were performed preoperatively and at 1 month and 1 year postoperatively.

Main Results:

• The piezoelectric device showed effective bone cutting in mastoidectomy with excellent control.
• No significant differences in operation time were observed compared to the microdrill.
• Patients treated with piezosurgery experienced a significantly shorter hospital stay (p < 0.05).

Conclusions:

• Piezosurgery is a safe and effective technique for mastoidectomy, preserving adjacent neurovascular and dural structures.
• The device offers precise bone cutting and promotes an efficient healing process.
• Piezosurgery leads to comparable operative times but reduced hospital stays, indicating improved patient recovery.
