Meatoplasty in a CWD Procedure Using an Endaural Approach: A Case Series of 31 Cases

Area of Science:

• Otolaryngology
• Surgical Techniques

Background:

• Canal wall down (CWD) mastoidectomy requires adequate meatoplasty for successful outcomes.
• The endaural approach is optimal for inside-out CWD mastoidectomy but has meatoplasty limitations.

Purpose of the Study:

• To describe a procedure for creating a large, adequate meatoplasty via an endaural route for inside-out CWD mastoidectomy.
• To evaluate the results of this technique in patients with unsafe ear disease and sclerotic mastoids.

Main Methods:

• A modified endaural approach was used for inside-out CWD mastoidectomy.
• The procedure involved raising a posterior skin flap and removing conchal cartilage for meatoplasty.
• Thirty-one cases of unsafe ear disease with sclerotic mastoids were included.

Main Results:

• The described technique successfully created a large, adequate meatoplasty.
• This facilitated a dry outcome in the treated cases of mastoidectomy.
• The endaural route with modified meatoplasty proved effective for inside-out CWD procedures.

Conclusions:

• A large meatoplasty can be achieved via the endaural route using a posterior skin flap and conchal cartilage removal.
• This technique is beneficial for inside-out CWD mastoidectomy, particularly in cases with sclerotic mastoids.
• The procedure contributes to achieving dry outcomes in mastoid surgery.
