Mucocele in an orbitoethmoidal (Haller's) cell (accidentally combined with acute contralateral dacryocystitis).
Haller's cells--according to recent terminology now called orbitoethmoidal cells (OEC)--are defined as anterior or posterior ethmoidal cells that have developed into the orbital floor. They can be excessively pneumatized and thus contribute to obstruction of the ostiomeatal complex area. We present the case of a 42 year old white male, who was admitted for treatment of an acute dacryocystitis on the right side. The CT scan revealed moderate sinusitis of the right ethmoid and maxillary sinuses and coincidentally a mucocele in an OEC on the left side. An endoscopic dacryocystorhinostomy on the right and a revision of the mucocele on the left side were performed in the same sitting. We consider both indications--stenosis of the nasolacrimal duct as well as mucoceles rewarding indications for endoscopic surgery. An external approach to the nasolacrimal duct in this case would have been problematic, as the external skin and soft tissue covering the duct already showed severe inflammatory changes. The operation of the up until that time asymptomatic mucocele was of prophylactic character. To our knowledge this is the first report of a mucocele developing in an OEC in the literature.
