Long noncoding RNAs (lncRNAs) are a novel class of potential biomarkers and therapeutic targets for the treatment of neoplasms. The purpose of this study was to explore the expression profile, potential functions, and diagnostic and clinical significance of lncRNAs in sinonasal inverted papilloma (SNIP). The expression profiles of lncRNAs and mRNAs were analyzed using a microarray. The potential functions and clinical implications of specific lncRNAs were further analyzed by bioinformatics and statistical methods. Microarray analysis identified 1,668 significantly upregulated and 1,767 downregulated lncRNAs in SNIP. Several mRNAs coexpressed with lncRNAs were enriched in some biological processes and cellular signaling pathways related to tumorigenesis. Lnc-AKTIP might interact with a variety of tumor-associated proteins and transcription factors, such as PCBP2, IRF-1, and p53. Receiver operating characteristic curve analysis for lnc-AKTIP showed an area under the curve of 0.939. Notably, its expression level was significantly decreased in SNIP tissues versus normal tissues and was associated with SNIP staging. Lnc-AKTIP may serve as a valuable diagnostic biomarker and a therapeutic target for SNIP.

Article Synopsis
- Sinonasal inverted papilloma (SNIP) has a high recurrence rate and the potential to become malignant, but its specific metabolic pathways and biomarkers are not fully understood.
- RNA sequencing identified significant gene alterations related to the estrogen biosynthesis pathway and highlighted five key biomarkers (AKR1B10, CYP1B1, CYP2C19, CYP3A5, and HSD17B13) that were correlated with SNIP pathogenesis.
- Functional analysis indicated that these biomarkers are involved in epithelial cell proliferation and EGFR signaling regulation, suggesting their potential as diagnostic and therapeutic targets for managing SNIP.

Background: Hyperostosis is a common radiographic feature of inverted papilloma (IP) tumor origin on computed tomography (CT). Herein, we developed a machine learning (ML) model capable of analyzing CT images and identifying IP attachment sites.
Methods: A retrospective review of patients treated for IP at our institution was performed.

Objective: Prior studies have been contradictory on the role of human papillomavirus (HPV) infection in sinonasal inverted papilloma (SNIP) recurrence. This systematic review and meta-analysis was performed to further evaluate this potential association.

Nasal and paranasal sinus masses can arise from a wide range of conditions, both benign and malignant, as well as congenital or acquired. Diagnosing these masses is often challenging, requiring a combination of nasal endoscopy, imaging studies, and histopathological analysis. Initial imaging frequently involves computed tomography or cone beam computed tomography (CBCT) to evaluate the bony anatomy of the nasal cavity and surrounding sinuses, while magnetic resonance imaging (MRI) is typically used for detailed assessment of soft tissues and to aid in differential diagnosis when the findings are inconclusive.

Background: To reduce recurrence rates of inverted papilloma (IP), some have argued for the use of intraoperative frozen margins; results remain mixed and studies critically lack lengthy surveillance periods.
Objective: We aim to elucidate the impact of prolonged surveillance and intraoperative frozen margins on IP recurrence.
Methods: This is a retrospective analysis of patients who underwent resection of IP at a tertiary care center over a 10-year period from 2008 to 2018 followed by subsequent surveillance.
