Ten cases of mucocele of the ethmoidal sinus developing as a complication of surgery sinus are reported.
Of the 10 cases, 3 showed visual disturbances.
Operative findings of the 10 cases suggested three different modes in the development of the mucocele; 1) adhesions of the uncinate process to the lateral mucosa of the middle turbinate, 2) obliteration above the infundibulum due to imcomplete removal of the bullae ethmoidea, 3) obliteration around the third ground lamella due either to imcomplete removal of the lammella or to postoperative proliferation of granulation and/or bone regeneration.
The authors suggested the following predisposing factors for the development of the mucocele; 1) operation in young patients, 2) combined intranasal and transantral procedure, 3) narrow ethmoidal sinus, 4) imcomplete procedure, 5) inadequate postoperative treatment and 6) postoperative distortion of the structure.
