Plasticity of the ethmoid sinus framework after endoscopic surgery, however, is a newly described entity. The objective of this study was to determine the incidence and extent of changes in ethmoid size after ethmoidectomy.<\/jats:p><jats:p><jats:bold>Study Design:<\/jats:bold> Retrospective review performed at an academic medical center.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> Computed tomography scans performed from 2006 through 2007 at the Massachusetts Eye and Ear Infirmary (n = 5,131) were reviewed to identify 100 consecutive patients who underwent sinus surgery and met inclusion criteria. Seven dimensions were measured for each pre\u2010 and postoperative scan (n = 200) using Voxar 3D software.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> Computed tomography scans performed before and 2 to 37 months after ethmoidectomy demonstrated a decrease of 1.1 \u00b1 1.6 mm in mean ethmoid cavity width at the level of the cribriform plate and posterior globe after surgery (<jats:italic>P<\/jats:italic> &lt; .0001). Twenty\u2010five patients (25%) had &gt;1 mm decrease in mean ethmoid width, and six patients (6%) had a decrease of &gt;2 mm (mean 3.1 \u00b1 0.9 mm). These findings seemed to be the result of postoperative bowing of the medial ethmoid walls with a corresponding increase in orbital volume. These volumetric changes resulted in a postoperative subclinical retrodisplacement (enophthalmos) of the globes (mean 0.2 \u00b1 0.8 mm, <jats:italic>P<\/jats:italic> = .008). The extent of surgery, including performance of frontal recess dissection (<jats:italic>P<\/jats:italic> = .007) and total ethmoidectomy (<jats:italic>P<\/jats:italic> = .021) were found to be independent predictors of the observed changes in sinus dimensions.<\/jats:p><jats:p><jats:bold>Conclusions:<\/jats:bold> Postsurgical plasticity of the ethmoid cavity is a new concept supported by observed changes in sinus dimensions after ethmoidectomy. These changes may reflect a loss of internal structural support and forces of contracture during the postoperative healing period.<\/jats:p>","DOI":"10.1097\/mlg.0b013e31818379cd","type":"journal-article","created":{"date-parts":[[2008,11,19]],"date-time":"2008-11-19T08:10:55Z","timestamp":1227082255000},"page":"2240-2244","source":"Crossref","is-referenced-by-count":14,"title":["Anatomical Changes of the Ethmoid Cavity After Endoscopic Sinus Surgery"],"prefix":"10.1002","volume":"118","author":[{"given":"Michael P.","family":"Platt","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mary E.","family":"Cunnane","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hugh D.","family":"Curtin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ralph","family":"Metson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2009,1,2]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0165-5876(96)01458-9"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.2500\/105065897781446676"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1067\/mhn.2002.125607"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijporl.2006.02.009"},{"key":"e_1_2_6_6_2","doi-asserted-by":"crossref","unstructured":"CunnaneMB PlattM CarusoP MetsonR CurtinD.Medialization of the lamina papyracea after endoscopic ethmoidectomy: comparison of preprocedure and postprocedure computed tomographic scans.
