Endoscopic modified Lothrop procedure for postoperative frontal mucocele

Area of Science:

• Otolaryngology
• Endoscopic Sinus Surgery
• Rhinology

Background:

• Postoperative frontal mucoceles can arise after sinus surgery.
• Management of these mucoceles can be challenging, often requiring revision surgery.
• Previous surgical interventions may complicate further treatment.

Purpose of the Study:

• To evaluate the efficacy of an endoscopic modified Lothrop procedure.
• To assess a technique that avoids bone resection in the lateral frontal recess and frontonasal duct.
• To determine the suitability of this procedure for managing postoperative frontal mucoceles.

Main Methods:

• Prospective assessment of six patients undergoing the endoscopic modified Lothrop procedure.
• Patients had a history of a mean of two prior sinus surgeries.
• Preservation of mucosa and bone in the lateral frontal recess and frontonasal duct.
• Creation of a large median drainage pathway in the frontal sinus floor.

Main Results:

• All six patients achieved a patent median drainage pathway.
• Patients were symptom-free at an average follow-up of 24.5 months.
• Scar formation was noted, but no revision surgeries were required.

Conclusions:

• The endoscopic modified Lothrop procedure is a useful surgical option for managing postoperative frontal mucoceles.
• Preserving key anatomical structures in the frontal recess may contribute to successful outcomes.
• This technique demonstrates efficacy in patients with a history of multiple sinus surgeries.
