Ethmoidal mucocoele in an 11 year old child: endoscopic marsupialization.
Pak Armed Forces Med J Jan ;59(3):251-2.

A paranasal sinus mucocoele is an epithelial lined, mucus containing sac that fills the sinus and is able to expand by alternative bone resorption and bone formation [1]. The frontal sinus (65%) is the most common site, followed by ethmoid (30%), maxillary (3-10%) and sphenoid sinuses (1%) [2]. Paranasal mucocoele usually affects adults, most commonly in the fourth to seventh decades of life [3]. They are extremely rare in children and adolescents [4]. Ethmoidal mucocoeles usually present with ophthalmic manifestations like orbital displacement, proptosis, diplopia and restricted eye movements. Frontoethmoidal mucocoeles have traditionally been treated by the external frontoethmoidectomy (Lynch-Howarth ) or an osteoplastic flap operation. With the introduction of endoscopic sinus surgical techniques, rhinologic surgeons now prefer transnasal endoscopic management [5]. The endoscopic surgery has become the procedure of choice for mucocoeles of the ethmoidal , maxillary and sphenoidal sinuses. Many authors have advocated preservation of the mucocoele mucosa with marsupialization [6]. We present a rare case of ethmoidal mucocoele in an 11 year old boy, treated with endoscopic endonasal marsupialization.
