Overview
Inverted ductal papilloma is a benign neoplasm arising from the Schneiderian epithelium of the paranasal sinuses and nasopharynx, characterized by its inverted growth pattern and potential for local invasion and recurrence 12.Diagnosis
Imaging Techniques: High-resolution microendoscopy (HRME) shows promise in differentiating inverted papilloma from normal sinonasal mucosa with high accuracy (89.9%) 1.
Histopathological Confirmation: Essential for definitive diagnosis, typically revealing characteristic inverted growth of epithelial cells 12.
Endoscopic Evaluation: Useful for assessing lesion extent and guiding surgical planning 2.Management
Surgical Approach:
- Lateral Rhinotomy: Traditionally recommended for comprehensive removal 2.
- Conservative Endoscopic Surgery: Feasible for localized, unilateral lesions without malignancy or recurrence risk, achieving total excision with endoscopic techniques 2.
Follow-Up: Regular endoscopic monitoring recommended post-surgery, with intervals varying based on initial extent and pathology 2.Special Populations
No Specific Guidance: Abstracts do not provide detailed recommendations for management in pregnancy, pediatrics, elderly, or patients with comorbidities 12.Key Recommendations
Utilize high-resolution microendoscopy for preoperative assessment to enhance diagnostic accuracy (Evidence: Moderate) 1.
Consider conservative endoscopic surgery for localized, unilateral inverted ductal papillomas without malignancy or recurrence risk, ensuring thorough follow-up (Evidence: Weak) 2.
Standardize postoperative endoscopic monitoring to detect recurrence early, tailored to lesion characteristics (Evidence: Expert opinion) 2.References
