Our results support the endoscopic approach as the treatment of choice when feasible in patients with inverted papilloma, combined in selected cases with external approaches. The Krouse and Cannady systems provided a good distribution of patients according to local control.

The aim of this study was to describe the endoscopic medial maxillectomy technique with preservation of the inferior turbinate in patients affected by maxillary sinonasal inverted papilloma. We retrospectively reviewed the clinical charts and surgical technique in six patients with paranasal sinus inverted papilloma. There were five males and one female, whose mean age at diagnosis was 60 years ranging between 57 and 65 years. No recurrences were diagnosed, and no nasal crusting was evidenced postoperatively. Nasal breathing was satisfying in all cases. Postoperative epistaxis was not observed, and none of the patients refereed to have epiphora after the surgery. This technique has been successfully performed, showing no recurrence to the present and allowing the preservation of a functional inferior turbinate.

The unilateral septal flap pedicle by anterior ethmoidal artery may be used for small and medium perforations with a pedicle smaller than 1 cm posterior to the axilla.

Background: Sinonasal mucosal melanoma is an aggressive malignancy with a 5-year survival rate ranging from 20% to 39%. Despite the evolving surgical and radiotherapy techniques, and introduction of immune-checkpoint inhibitor therapy, overall survival rates remain poor. Methodology: A retrospective cohort study was conducted at the Hospital Clínic de Barcelona and the Hospital de la Santa Creu i Sant Pau between 1984 and 2020; primary outcome measures were 3 and 5-year melanoma-specific survival (MSS). Kaplan-Meier survival analysis and Cox proportional hazards model were performed to identify predictors of survival. Results: Fifty patients were included, the mean age was 70.4, MSS at 3 and 5 years was 51.2%, and 29.5%, respectively. The median follow-up was 39.6 months during which 46% presented locoregional recurrence and 36%, metastasis. The univariate and multivariate analyses found as survival predictors the N category, the treatment received, the surgical margins and the mitotic index. Conclusions: We found an overall 5-year MSS of 29.5%. Those patients with intention-to-cure (stages III and IVa) treated by surgery that were N0 at diagnosis, with < 10 mitoses per HPF showed a 5-year MSS rate of 74.1%. More studies will be needed to adequately define the patients’ profiles that will benefit from a better survival outcome.
