Functional endoscopic sinus surgery has become the preferred surgery for a variety
of sinonasal pathologies. Lesions confined to the posterior ethmoid sinuses or to
the posterior sphenoethmoidal complex are usually treated by the conventional "anterior
to posterior" approach. This procedure requires removal of the anterior ethmoids,
which might impair the anatomical and functional integrity of the ostiomeatal complex
(OMC). Here we describe our experience with an effective and minimally invasive surgical
approach to treat these posterior lesions while preserving the OMC. Medical records
of patients who underwent trans-superior meatal posterior ethmoidectomy or posterior
sphenoethmoidectomy with OMC preservation during functional endoscopic sinus surgery
between 2016 and 2021 were analyzed. Twelve patients were included in the study. Their
diagnosis included sinusitis (5 patients), fungus ball (3), inverted papilloma (2),
allergic fungal sinusitis (1) and mucocele (1). No intraoperative or postoperative
complications occurred, and all patients recovered rapidly. Lesions confined to the
posterior ethmoids or posterior sphenoethmoidal complex can be treated with trans-superior
meatal posterior ethmoidectomy or posterior sphenoethmoidectomy.
