“…Hypervascularization within the origin site may cause bone growth (31), driven by bone morphogenetic protein 4 expressed by SIP cells (33) or cytokines released due to inflammation (34). Bhalla et al (34) found that the predictive value of osteitis was 95% via CT scan, and similar results were also reported by Yousuf et al (35). Lee et al (31) evaluated 55 lesions associated with focal hyperostosis using CT images and revealed that the location of hyperostosis coincided with the actual tumor attachment sites in 49 (89.1%) of all the lesions.…”

Abstract. Sinonasal inverted papilloma (SIP) is a benign tumor of the nasal cavity and sinus. SIP is characterized by aggressive malignant transformation and a high rate of recurrence. Inadequate removal of the tumor during surgery is one of the most significant contributors to SIP recurrence. A growing body of evidence suggests that molecular alteration in SIP, including human papilloma virus infections, single nucleotide polymorphisms of key genes, deregulation of signaling pathways and immunological changes, may lead to SIP occurrence and malignant transformation. However, the extent to which these molecular mechanisms contribute to SIP pathology and transformation remains unclear due to limited research. Further studies are warranted to elucidate the primary dependent factors that contribute to SIP etiology. The present article reviewed risk factors of progression and recurrence of SIP, including outdoor and industrial occupational exposure, smoking, septal deviation, SIP location, recurrent cases, stage of SIP-associated squamous cell carcinoma and choice of surgical method.

“…35 There is a high correlation between the origin of the inverted papilloma and the presence of focal hyperostosis on the pre-operative CT; this may facilitate pre-operative prediction of tumour origin. [35][36][37] Magnetic resonance imaging There is no signature MRI appearance for benign inverted papilloma. The main utility of MRI is in defining the extent of the lesion and differentiating inverted papilloma from inspissated mucus.…”

In order to compare different studies and to enable meta-analysis of the literature, there should be a universally accepted staging and classification system for sinonasal inverted papilloma. Further research on the aetiology of sinonasal inverted papilloma, and on biological markers for its recurrence and malignant transformation, is required. To enable meaningful future research, we would encourage multicentre participation with a consensus on management.

The transition from external approaches to an endonasal corridor has seen a significant decline in patient morbidity and inpatient care. Our Rhinology and Cranial Base Surgery Group has been able to focus on the management of certain pathologies, endoscopic access to various areas in the skull base, reconstruction of the defect, ensuring that clear anatomical landmarks can be identified during the surgery, and improving the quality of life/function after treatment. The focus on surgical treatment is always to control disease and cure patients by not only reducing recovery time and perioperative morbidity, but also decreasing the long-term impact of having a tumour removed. With a dedicated combined operating theater setting with updated instrumentation, the Neuro-ENT team is able to continue to expand and develop endoscopic care for a greater number of patients and wider range of pathologies. The collaborative Neuro-ENT to work closely via the nose using the two-hole and four-hand technique when performing the operation simultaneously is of added advantage in the diverse and expanding field of cranial base surgery. Our skull base team is joined by expert radiation and medical oncologists who provide essential adjunctive care in the multidisciplinary management of these patients.

Site of Attachment of Inverted Papilloma Predicted by CT Findings of Osteitis

Abstract: In patients in whom osteitis is detectable on the preoperative CT scan, the site of origin of the IP can be predicted with a high degree of accuracy.
