Effect of alar nasal valve stent on nasal breathing.

Purpose: Lateral nasal wall insufficiency has previously been a surgical challenge. In 2018, the Alar Nasal Valve Stent (Medtronic) was taken into use at Helsinki University Hospital. The alar cartilages are repositioned and locked into position with the Alar Nasal Valve Stent on the mucosa.

Sinonasal inverted papilloma - malignant transformation and non-sinonasal malignancies.

Objectives: To assess malignant transformation rate, non-sinonasal malignancies, and factors contributing to recurrence in patients treated for sinonasal inverted papilloma (SNIP).

Study Design: Retrospective study.

Methods: We retrospectively reviewed medical records of all patients treated for SNIP (n = 296) between the years 1984-2014 at Helsinki University Hospital.

HPV-Positive Status Is an Independent Factor Associated With Sinonasal Inverted Papilloma Recurrence.

Objectives: The present study aimed to evaluate human papillomavirus (HPV) occurrence in sinonasal inverted papilloma (SNIP), and to assess factors associated with HPV positivity and SNIP recurrence.

Study Design: Prospective study.

Methods: We prospectively collected clinical data and fresh tissue specimens from 90 consecutive patients treated for SNIP at Helsinki University Hospital, between 2015 and 2019.

Eosinophilia, asthma, NERD and the use of oral corticosteroids predict uncontrolled chronic rhinosinusitis with nasal polyps after surgery.

Background: Severe uncontrolled chronic rhinosinusitis with nasal polyps (CRSwNP) is a challenging condition to treat. The European Position Paper on Rhinosinusitis and Nasal Polyps 2020 (EPOS2020) has the following criteria when considering biological therapy for severe uncontrolled CRSwNP: eosinophilia, need for oral corticosteroids (OCS), symptom score, loss of sense of smell and co-morbid asthma.

Objective: This study aimed at finding associations of baseline factors with uncontrolled CRSwNP after endoscopic sinus surgery (ESS).
