  4. Inverted papilloma involving maxillary sinus, ethmoid and right nasal cavity, with aspect of cerebriform circumvolutions. Several IP classifications have been published. In 2000, Krouse developed a classification based on tumor extension assessed on radiology (Table 1)
  5. METHODS: From 2000 to 2011, 50 patients with maxillary sinus inverted papilloma were treated with intranasal endoscopic surgery or combined approach. Among them, 39 cases were primary and 11 cases were recurrent, which included 17 patients with Krouse stage IIand 33 cases with Krouse stage III
  6. Inverted papilloma (IP) is an uncommon sino-nasal neoplasm with potentially distinctive MRI and CT features. The MR striated imaging pattern has been reported as a valuable MR imaging feature of IP. The purpose of this study was to validate the usefulness of this sign using detailed criteria of the sign itself
  7. Inverted papillomas most commonly occur on the lateral wall of the nasal cavity, most frequently related to the middle turbinate/middle meatus and maxillary ostium, although they are seen elsewhere in the nasal passage. As the mass enlarges it results in bony remodeling and resorption and often extends into the maxillary antrum 1

An inverted papilloma is an uncommon benign sinonasal tumor with distinctive pathological and imaging features. MRI is very useful if delineating the extent of the mass in relation to post-obstructive fluid and the sinuses involved to aid the surgical approach. The CT is essential in outlining bony destruction Inverted papilloma is the most common subtype, followed by exophytic papilloma; oncocytic papilloma is the least common Inverted and oncocytic papilloma most commonly affect patients in their 5th to 6th decades, while exophytic papilloma occurs in 3rd to 5th decade The human papilloma virus (HPV) can produce a benign (non-cancerous) sinus tumor called inverted papilloma. Diagnosis To make a diagnosis of nasal cavity cancer or sinus cancer the doctor will ask questions about your symptoms, medical history, and examine your mouth Inverted papillomas are well known to exhibit centrifugal growth pattern. 3, 14 For example, even if the tumor of nasal cavity also extends to the medial wall of the maxillary sinus and fills the antrum, endoscopic medial maxillectomy is not required, provided the tumor origin is still localized in the nasal cavity A computed tomography scan revealed a mass filling the right maxillary sinus, destroying bone and invading the inferolateral orbit. The tumor proved to be an inverted squamous papilloma with focal transformation to squamous cell carcinoma

  1. Inverted papilloma (IP) of the nasal cavity and paranasal sinuses is a benign tumor that accounts for 0.5-4% of all sinonasal tumors [ 1 ]
  2. More than 80% of all inverted papillomas involve both the nasal cavity and sinuses, with only 5% involving the sinus exclusively - usually found at the maxillary and ethmoid sinus only [4,5]. Despite the limited literature and the rarity of isolated sphenoid inverted papillomas, there is an increasing detection rate due to the expanding use.
  3. Inverted papilloma had adhered to the anterior, medial, and inferior walls; that is, it adhered to the entire circumference of the maxillary sinus. It was considered that there were all IP-involved mucosae without normal mucosa inside the maxillary sinus
  4. The three most distinct forms are fungiform, cylindric, and inverted papillomas, with inverted papillomas accounting for approximately 47% of all nasal papillomas . Inverted papillomas are benign epithelial neoplasms that classically arise from the lateral nasal wall or maxillary sinus and have significant malignant potential
  5. Endoscopic sinus surgery is particularly useful for inverted papillomas in the lateral nasal and nasal cavity, middle meatus, maxillary sinus, and the anterior and posterior ethmoid cells. The procedure largely consists of tumor debulking through a microdebridder until the origin is identified, and then lesions are usually excised en bloc from.

Sinonasal papilloma is a non-cancerous tumour that starts in the nasal cavity or sinus. Sinonasal papillomas are divided into three types called inverted, exophytic, and oncocytic. If not removed completely, the inverted type can grow into and damage surrounding tissues including the bones of the face and the base of the skull There are several differential diagnoses of unilateral sinus disease. One of these is inverted papilloma (IP) of the maxillary sinus, which is a common benign tumor with a substantial rate of malignant transformation. In general, endoscopic endonasal techniques for addressing the tumor are favored nowadays instead of classical external approaches
