“…Komplikasi mukosisl berupa destruksi tulang dan ekstensi ke intrakranial dilaporkan sebesar 10-55%. 3,4 Penyebab mukosil masih belum diketahui dengan pasti. Obstruksi ostium sinus diduga merupakan penyebab utama, sehingga terjadi adhesi pascainflamasi, pascatrauma atau pascaoperasi.…”

Mukosil sinus paranasal merupakan lesi kistik pada sinus, dihasilkan dari akumulasi sekresi mukus dan deskuamasi epitel akibat obstruksi kronis dari osteum sinus. Mukosil memiliki sifat tumbuh lambat, sering di area sinus frontal dan etmoid, namun jarang terjadi bilateral asimetris. Mukosildapat menyebabkan distensi dinding sinus, sehingga dapat menimbulkan komplikasi ke area sekitarnya, terutama area mata. Dilaporkan satu kasus mukosil sinus fronto-etmoidalis asimetris bilateral dengan komplikasi orbita unilateral di Rumah Sakit Dr.Hasan Sadikin.Wanita 67 tahun dengan gejala klinis proptosis nonaksial pada orbita kanan, tanpa disertai diplopia, gangguan gerak bola mata maupun visus. Pasien memiliki riwayat bekerja di pabrik pembakaran genteng selama puluhan tahun. Metode pemeriksaan nasoendoskopi dan CT Scan menunjukkan mukosil bilateral asimetris pada sinus frontal-etmoid.Dilakukan prosedur pengangkatan mukosil dengan pendekatan marsupialisasi secara endoskopik. Pascaoperasi didapatkanhasil perbaikan gejala proptosis dan tidak terdapat rekurensi mukosil.Penatalaksanaan segera pembedahan endoskopik pada mukosil sinus frontoetmoidalis dapat memperbaiki komplikasi proptosis dengan morbiditas yang rendah dan luka operasi yang minimal, dibandingkan bedah terbuka.Kata kunci: Mukosil sinus frontoetmoidal, proptosis, pembedahan endoskopi sinus

Introduction: Mucoceles are cystic masses developing after obstruction of the sinus ostium. The symptoms are not specific. Computed Tomography scan (CT scan) and Magnetic Resonance Imaging (MRI) confirm the diagnosis. Objectives: We herein review the radiologic characteristics of mucoceles in CT scan and MRI. Materials and Methods: We report a retrospective study of 43 patients diagnosed with paranasal sinuses mucoceles. CT scans were performed for all patients, but MRI was carried out only in selected cases. Results: Our study was constituted of 27 males and 16 females with a mean age of 47 years. The CT scan appearence of mucoceles were in all cases as a well circumscribed expansile sinus mass with an effect on the neighbor bone structure. This mass was hypodense in 26 cases, isodense in 14 cases and hyperdense in 3 patients. The paranasal sinuses most frequently affected in our series were the fronto-ethmoidal sinuses. The most affected bone eroded was the lamina papiracea. Intracranial extension was seen in four cases. CT scan allowed to predict the cause of mucoceles in some cases and to provide information about anatomic variants. MRI was realized for 15 patients in addition to the CT scan. It allowed to study the extension of mucoceles to the neighboring organs especially orbital and endocranial ones. Conclusion: The presentations of mucoceles on imaging are quite variable. CT scan provides precious information about the location, bone erosion and extension of the mucoceles. MRI is indicated in some cases especially in cases of orbital or cranial extension.

Objective Paranasal sinus mucoceles are benign cystic lesions originating from sinus mucosa that can impinge on adjacent orbital structures, causing ophthalmic sequelae such as decreased visual acuity. Definitive treatment requires surgery. We present the first meta-analysis quantifying the effect of preoperative visual function and time to surgery on postoperative visual acuity outcomes. Data Sources PubMed, Ovid, Embase, Web of Science, and the Cochrane Library. Methods Two independent authors systematically reviewed articles describing outcomes after endoscopic sinus surgery for paranasal sinus mucoceles presenting with visual loss. Available data from case reports and series were combined to analyze the associations among preoperative visual acuity, time to surgery, and postoperative outcomes. Results Eighty-five studies were included that provided data on 207 patients. The average presenting visual acuity was 1.57 logMAR (logarithm of the minimum angle of resolution), and the average postoperative visual acuity was 0.21 logMAR, with visual improvement in 71.5% of cases. Preoperative visual acuity ≥1.52 logMAR correlated with postoperative improvement >1 logMAR (R = 0.4887, P<.0001). A correlation was found between a time to surgery <6 days and postoperative improvement (R = 0.297, P <.0001). Receiver operator curve analysis of these thresholds demonstrated a moderately accurate prognostic ability (area under the curve: 75.1 for preoperative visual acuity and 73.1 for time to surgery). Conclusion Visual loss resulting from paranasal sinus mucoceles is potentially reversible in most cases, even those presenting with poor vision. When possible, surgery should be performed promptly after diagnosis, but emergency surgery does not appear to be necessary for vision restoration.
