Summary
Inverted nasosinusal papilloma, a rare nasal tumor, was studied in 13 patients. Surgical removal yielded satisfactory results, but recurrences and malignant transformation were noted, emphasizing the need for regular follow-up.
Area of Science:
- Otorhinolaryngology
- Oncology
- Pathology
Background:
- Inverted nasosinusal papilloma (INP) is a rare, unilateral tumor affecting nasal and paranasal sinus mucosa.
- This study investigates INP cases treated at Brazzaville University Hospital's ENT department.
Observation:
- A retrospective analysis of 13 patients treated between 1988 and 2001.
- The primary symptom was chronic nasal obstruction (12 cases), with an average age of 34.
- Histological diagnosis confirmed INP, with rare associations with Killian polyp, HPV, and rhinosporidiosis.
Findings:
- Surgical interventions, including Caldwell-Luc and para-latero-nasal approaches with tumor insertion site diathermy, achieved satisfactory outcomes.
- Recurrences were observed in 4 cases (average 4 years post-surgery).
- Malignant transformation occurred in 2 cases, one associated with Human Papilloma Virus (HPV) infection.
Implications:
- Histological examination is crucial for all naso-sinusal polypoid lesions.
- Regular patient follow-up is essential but challenging in African healthcare settings.
