[The atypical course of subperiosteal abscess of the orbital wall].

The authors describe a clinical case of malformation of intranasal structures of the lateral wall and the middle turbinated bone of the nose (bullous middle turbinated bone, lateral position of the middle turbinated bone, hypertrophy of ethmoidal bulla and uncinate process) in combination with expressed deformation of the nasal septum. These malformations were responsible for the development of acute hemisinusitis complicated by subperiosteal abscess of the superomedial orbital wall. Conjunctival chemosis was impossible to remove by traditional medicamental therapy and surgical intervention. Hirudotherapy produced the well-apparent anti-odematous, anti-inflammatory, anti-coagulative, and thrombolytic effects that resulted in reduced conjunctival oedema and marked positive dynamics of the state of the eyeball. Subcutaneous administration of anticoagulants was used to prevent thrombosis of orbital veins and cerebral venous sinuses.
