Patients were grouped as primary and recurrent cases, and later at follow\u2010up, depending on disease status, they were subcategorized into \u2018primary with no recurrence\u2019 (PnR), \u2018primary with recurrence\u2019 (PwR), \u2018recurrent with no further recurrence\u2019 (RnR) and \u2018recurrent with further recurrence\u2019 (RwR) groups. Radiological and surgical data were collected and analysed.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Among the 117 patients, zygomatic recess was anatomically the most prevalent maxillary recess. Palatonasal was the most commonly affected recess in both primary and recurrent groups. Within the maxillary sinus, the most common sites of recurrence were the lateral wall and floor. Anterior ethmoid (\n p<\/jats:italic>\n \u2009=\u20090.047), frontal recess (\n p<\/jats:italic>\n \u2009=\u20090.017) and frontal sinus (\n p<\/jats:italic>\n \u2009=\u20090.026) showed significantly higher radiological involvement in recurrent cases compared to primary cases. Among the recurrent cases, involvement of posterior ethmoid (\n p<\/jats:italic>\n \u2009=\u20090.030), frontal recess (\n p<\/jats:italic>\n \u2009=\u20090.017), intraorbital extraconal compartment (\n p<\/jats:italic>\n \u2009=\u20090.036) and Krouse stage T4 (\n p<\/jats:italic>\n \u2009=\u20090.002) were significantly higher in those with repeated disease recurrence (RwR).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n In recurrent IP, predictors of repeated recurrence include the site of initial recurrence being the frontal recess\/sinus region, involvement of the posterior ethmoid, frontal recess and intraorbital extraconal compartment, and Krouse stage T4 at the time of diagnosis.<\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/coa.70046","type":"journal-article","created":{"date-parts":[[2025,10,6]],"date-time":"2025-10-06T23:59:44Z","timestamp":1759795184000},"page":"127-135","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Sinonasal Inverted Papilloma\u2014Relevance of Radiological Anatomy in Disease Recurrence"],"prefix":"10.1111","volume":"51","author":[{"given":"Rakesh R.","family":"Bright","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology Christian Medical College Vellore India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Madhavi","family":"Kandagaddala","sequence":"additional","affiliation":[{"name":"Department of Radiology Christian Medical College Vellore India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lisa Mary","family":"Cherian","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Christian Medical College Vellore India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1857-6019","authenticated-orcid":false,"given":"Regi","family":"Kurien","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Christian Medical College Vellore India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vedantam","family":"Rupa","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Christian Medical College Vellore India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Belavendra","family":"Antonisamy","sequence":"additional","affiliation":[{"name":"Department of Biostatistics Christian Medical College Vellore India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aparna","family":"Irodi","sequence":"additional","affiliation":[{"name":"Department of Radiology Christian Medical College Vellore India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9281-7071","authenticated-orcid":false,"given":"Lalee","family":"Varghese","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Christian Medical College Vellore India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,10,6]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.5402\/2012\/175903"},{"key":"e_1_2_13_3_1","doi-asserted-by":"publisher","DOI":"10.1155\/2017\/9195163"},{"key":"e_1_2_13_4_1","doi-asserted-by":"publisher","DOI":"10.3390\/jcm11113020"},{"key":"e_1_2_13_5_1","first-page":"618","article-title":"Focal Hyperostosis on CT of Sinonasal Inverted Papilloma as a Predictor of Tumour Origin","volume":"28","author":"Lee D.
