Management of sinonasal inverted papilloma: endoscopic approach and lateral rhinotomy

Objective: To compare endoscopic approach with lateral rhinotomy for treatment of the sinonasal inverted papilloma in terms of advantage, indications and limitations of the procedures.

Methods: Eighty-six cases with inverted papilloma were reviewed retrospectively, among which 23 cases underwent transnasal endoscopic procedures including 10 combined with Caldwell-Luc intervention, and 63 cases underwent lateral rhinotomy. The follow-up period ranged from 11 - 36 m (mean 23 m). The data were processed statistically by SPSS 10.0 software. Result: Both procedures permitted removal of most sinonasal inverted papilloma. The endoscopic surgery provided an excellent visualization, and preserved a vital anatomic structure and left no facial scar. Lateral rhinotomy was associated with postoperative facial scar or deformity. The recurrence rate in lateral rhinotomy group was 9.5% and in endoscopic approach was 13% (P >0.05).

Conclusion: Endoscopic approach is favored for the treatment of non-massively extending sinonasal inverted papilloma because of an acceptable recurrence and a better cosmetic results.
