Mucocele of ethmoidal labyrinth as complicatioin of transethmoidal orbital decompression. Clinical case

The mucocele of paranasal sinuses is quite seldom found pathology which is followed by appreciable damages of a mucosa, a bone tissue with possible intracranial and intraorbital complications. We represent a clinical case of a mucocele of the ethmoidal labyrinth as a complication after the transetmoidal endoscopic decompression of an orbit (TEDO) made concerning an endocrine ophthalmopathy. The postoperative diplopia which arises, according to different authors, in 6-38% of cases belongs to the most frequent complications of TEDO. Cases of emergence of the rinosinusit after the decompression of an orbit in 4-11% of cases and isolated cases of a liquorrhea from area of a clinoid sinus are also described. The feature of our clinical case is that it is the only case of a complication of iatrogenic character after an endoscopic transetmoidalny orbitotomy registered in our clinic.
