[Nasal polyps of olfactory sulcus]

Area of Science:

• Otolaryngology
• Rhinology
• Surgical Anatomy

Context:

• Olfactory sulcus polyps (OSP) are a specific type of sinonasal polyp.
• Understanding OSP origin is crucial for effective surgical planning.
• Olfactory dysfunction is a common symptom associated with sinonasal pathology.

Purpose:

• To investigate the anatomical origins of olfactory sulcus polyps.
• To assess olfactory function recovery following functional endoscopic sinus surgery (FESS).
• To determine the optimal surgical approach for OSP.

Summary:

• A review of 59 OSPs in 31 patients identified the posterior ethmoid sinus mucosa as the most common origin (69.5%), specifically the superior meatus and ethmoid cells near ostia.
• Other origins included the middle turbinate (8 sides), superior turbinate (4 sides), and combined ethmoid/sphenoid sinus mucosa (6 sides).
• Post-operative olfactory assessment in 26 patients showed significant improvement in 52% within three months, with slower recovery in those with recurrent polyps or associated chronic rhinosinusitis.

Impact:

• Identifies key anatomical sites for OSP development, aiding surgical navigation.
• Demonstrates the efficacy of FESS in restoring olfactory function for OSP patients.
• Supports minimal endoscopic sinus surgery as the preferred treatment for OSP, potentially improving patient outcomes and quality of life.
