Baseline abscess volumes were measured on dedicated segmentation software for analyzing imaging findings. SPA volumes of needle aspirations were compared with those following I&D. Outcomes were compared.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n In total, 99 patients (median [interquartile range] age 26 [11\u201335] months) were enrolled. The mean\u2009\u00b1\u2009standard deviation white blood cell (WBC) counts and C\u2010reactive protein (CRP) levels were 14.5\u2009\u00b1\u20097.0\u2009K\/\u03bcL and 112\u2009\u00b1\u200942\u2009mg\/dL, respectively. Fifty\u2010seven patients were treated by needle aspiration and 42 by I&D. Age, WBC counts, and CRP levels were similar for both groups, as were SPA volumes as seen on imaging studies 2.0\u2009\u00b1\u20091.0\u2009cm\n 3<\/jats:sup>\n for the former group and 2.0\u2009\u00b1\u20090.9\u2009cm\n 3<\/jats:sup>\n for the latter group (\n p<\/jats:italic>\n \u2009=\u20090.955). Resolution rates were 75.4% and 76.2%, respectively (\n p<\/jats:italic>\n \u2009=\u20090.931). Resolved SPAs after needle aspiration and I&D had similar volumes 1.7\u2009\u00b1\u20090.9 and 1.7\u2009\u00b1\u20090.7\u2009cm\n 3<\/jats:sup>\n , respectively,\n p<\/jats:italic>\n \u2009=\u20090.931.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n \n Both needle aspiration and I&D are safe methods to reduce the infective and inflammatory load and provide pus for culture. Higher volumes (~3\u2009cm\n 3<\/jats:sup>\n and more) should be managed initially with cortical mastoidectomy since the risk of no improvement following needle aspiration or I&D is higher.\n <\/jats:p>\n <\/jats:sec>\n \n Level of Evidence<\/jats:title>\n 3.<\/jats:p>\n <\/jats:sec>","DOI":"10.1002\/lary.32083","type":"journal-article","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T07:03:25Z","timestamp":1740121405000},"page":"2513-2520","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["The Significance of Subperiosteal Abscess Volume in Acute Mastoiditis"],"prefix":"10.1002","volume":"135","author":[{"given":"Rani","family":"Abu\u2010Eta","sequence":"first","affiliation":[{"name":"Departments of Otolaryngology\u2010Head and Neck Surgery and Maxillofacial Surgery Tel Aviv Sourasky Medical Center Tel Aviv Israel"},{"name":"School of Medicine Tel\u2010Aviv University Tel Aviv Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ramez","family":"Salameh","sequence":"additional","affiliation":[{"name":"Departments of Otolaryngology\u2010Head and Neck Surgery and Maxillofacial Surgery Tel Aviv Sourasky Medical Center Tel Aviv Israel"},{"name":"School of Medicine Tel\u2010Aviv University Tel Aviv Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2356-9147","authenticated-orcid":false,"given":"Yahav","family":"Oron","sequence":"additional","affiliation":[{"name":"Departments of Otolaryngology\u2010Head and Neck Surgery and Maxillofacial Surgery Tel Aviv Sourasky Medical Center Tel Aviv Israel"},{"name":"School of Medicine Tel\u2010Aviv University Tel Aviv Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6905-3034","authenticated-orcid":false,"given":"Ophir","family":"Handzel","sequence":"additional","affiliation":[{"name":"Departments of Otolaryngology\u2010Head and Neck Surgery and Maxillofacial Surgery Tel Aviv Sourasky Medical Center Tel Aviv Israel"},{"name":"School of Medicine Tel\u2010Aviv University Tel Aviv Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nidal","family":"Muhanna","sequence":"additional","affiliation":[{"name":"Departments of Otolaryngology\u2010Head and Neck Surgery and Maxillofacial Surgery Tel Aviv Sourasky Medical Center Tel Aviv Israel"},{"name":"School of Medicine Tel\u2010Aviv University Tel Aviv Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5904-1291","authenticated-orcid":false,"given":"Omer Jacob","family":"Ungar","sequence":"additional","affiliation":[{"name":"Departments of Otolaryngology\u2010Head and Neck Surgery and Maxillofacial Surgery Tel Aviv Sourasky Medical Center Tel Aviv Israel"},{"name":"School of Medicine Tel\u2010Aviv University Tel Aviv Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,2,21]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijporl.2014.09.032"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijporl.2007.06.022"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijporl.2012.02.042"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0000000000002231"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1996.01890140023006"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0194-5998(98)70100-7"},{"key":"e_1_2_8_8_1","first-page":"183","article-title":"15 Surgery of Acute Infections and Their Complications","author":"Neely J.
