Frontal sinus ablation (Riedel-Mosher’s procedure): indications and role in the endonasal endoscopic era

Area of Science:

• Neurosurgery
• Otolaryngology
• Plastic Surgery

Background:

• The Riedel-Mosher procedure is a surgical technique for frontal sinus and bone pathologies.
• Its current role in the endoscopic endonasal era needs evaluation.
• Available materials for frontal reconstruction are also reviewed.

Purpose of the Study:

• To describe the Riedel-Mosher surgical technique.
• To identify its current role in the endoscopic endonasal era.
• To review materials for frontal reconstruction.

Main Methods:

• Retrospective review of patients undergoing the Riedel-Mosher procedure from 2005 to 2018.
• Data collected on surgical technique, reconstruction timing, and materials used.

Main Results:

• 21 patients (15-84 years) underwent the procedure for chronic osteitis, benign tumors, or malignancy.
• 3 perioperative complications occurred.
• Cranioplasty was performed in 16 cases, delayed by an average of 10 months.
• Reconstruction materials included titanium, ceramic, plastic, and free flaps.

Conclusions:

• The Riedel-Mosher procedure is still indicated for selected benign and malignant frontal sinus/bone pathologies.
• Surgical expertise is essential for safe frontal sinus approaches.
• Successful reconstruction requires planning and diverse material options.
