Abstract:
Aspergillosis is a common fungal infection of the paranasal sinuses. Isolated frontal sinus aspergillosis is extremely rare, with only three cases reported in the literature. We report a case of isolated frontal sinus aspergillosis that was accompanied by a contralateral frontal sinus cyst enclosed osseously. The patient was treated successfully by an endoscopic modified Lothrop procedure that permitted complete removal of the fungus ball and wide opening of the frontal sinus. The patient is without evidence of disease 18 months after surgery.
Insights
Isolated frontal sinus aspergillosis, a rare fungal infection, was successfully treated using an endoscopic modified Lothrop procedure. This approach allowed complete fungus ball removal and sinus opening, with no recurrence after 18 months.
Area of Science:
- Otolaryngology
- Mycology
- Surgical Innovation
Background:
- Aspergillosis commonly affects paranasal sinuses.
- Isolated frontal sinus aspergillosis is exceptionally rare, with limited documented cases.
- Concurrent osseously enclosed contralateral frontal sinus cysts present unique challenges.
Observation:
- A rare case of isolated frontal sinus aspergillosis is presented.
- The condition was associated with a contralateral frontal sinus cyst.
- The cyst was completely enclosed within the bone.
Findings:
- Successful endoscopic modified Lothrop procedure for treatment.
- Complete removal of the fungal ball (aspergillosis).
- Achieved wide opening of the frontal sinus.
Implications:
- Demonstrates the efficacy of the endoscopic modified Lothrop procedure for rare frontal sinus aspergillosis.
- Highlights a potential surgical approach for complex sinus pathologies.
- Suggests favorable long-term outcomes with this minimally invasive technique.
