Cholesteatoma surgery: open vs closed tympanoplasty

Area of Science:

• Otolaryngology
• Surgical Innovation

Background:

• Cholesteatoma management remains a significant challenge in otologic surgery.
• Tympanoplasty techniques, including open (canal wall down) and closed (canal wall up) approaches, are employed for extensive cholesteatoma.
• Comparing the long-term outcomes of these techniques is crucial for surgical decision-making.

Purpose of the Study:

• To compare the outcomes of closed tympanoplasty (canal wall up) versus open tympanoplasty (canal wall down) in patients with extensive cholesteatoma.
• To evaluate differences in postoperative subjective problems, auditory results, and cholesteatoma recurrence rates between the two surgical approaches.

Main Methods:

• A retrospective study of 11 years of patient data involving closed and open tympanoplasty for extensive cholesteatoma.
• Analysis of subjective postoperative issues, audiometric results, and rates of cholesteatoma recurrence.
• Comparison of outcomes between canal wall up and canal wall down tympanoplasty procedures.

Main Results:

• No significant differences were observed in postoperative subjective problems or auditory outcomes between open and closed tympanoplasty.
• Canal wall up (closed) tympanoplasty demonstrated a higher rate of cholesteatoma recurrence, often necessitating a two-stage procedure.
• Open tympanoplasty (canal wall down) showed a lower incidence of postoperative cholesteatoma complications.

Conclusions:

• Removal of the canal wall is essential for minimizing cholesteatoma recurrence.
• Open tympanoplasty is a viable alternative to closed tympanoplasty, particularly when preserving the canal wall is contraindicated or multi-stage surgeries are not feasible.
• Surgical technique selection should consider patient-specific factors and the goal of reducing cholesteatoma recurrence.
