Sphenoid Sinus Fungal Ball and Reestablishing Sinus Function

Area of Science:

• Otolaryngology
• Rhinosinusology
• Medical Imaging

Background:

• Sphenoid sinus fungal balls (SSFB) are a clinical concern.
• Understanding the anatomical factors predisposing to SSFB is crucial for effective management.
• Mucociliary dysfunction can contribute to fungal ball formation.

Purpose of the Study:

• To evaluate developmental attributes of sphenoid sinuses affected by fungal balls.
• To describe a surgical technique for restoring gravity-dependent drainage.
• To mitigate mucociliary dysfunction in SSFB cases.

Main Methods:

• Within-patient case-control analysis of sphenoid sinus dimensions in SSFB patients.
• Radiological assessment of sinus volume, width, and pneumatization.
• Documentation of sinus patency and mucostasis post-surgery.
• Recording of surgical complications.

Main Results:

• Fungal balls were significantly more common in smaller, nondominant sphenoid sinuses (p < 0.01).
• Sinus size, not pneumatization variants, influenced SSFB development.
• All patients achieved patency and absence of mucostasis post-surgery without complications.

Conclusions:

• The smaller, nondominant sphenoid sinus is more susceptible to fungal ball formation.
• Surgical reshaping to ensure gravity-dependent drainage is beneficial for managing smaller affected sinus cavities.
• The described surgical approach effectively prevents mucostasis and inflammation.
