Abstract
Although mucoceles of the frontal, ethmoid and sphenoid sinuses are less common than those of the maxillary sinuses, patients in the former group suffer from a wider variety of symptoms than those in the latter. Eye ball disturbances are generally accepted as one of the most important symptoms. Nineteen cases of frontal, ethmoid and sphenoid sinus mucoceles were treated surgically in our clinic over the past three years from November, 1981 to December, 1984. Data obtained from these cases are discussed. Results are summarized as follows; 1) Origin of the mucoceles was found in thirteen cases of frontal sinuses, four cases of ethmoid sinuses and two cases of sphenoid sinuses. 2) Four cases were recognized as primary cysts and fifteen cases were secondary cysts. 3) These mucoceles were found relatively frequently in patients in their thirties and fourties, and the male to female ratio was 13:6. 4) Many of the secondary cyst cases were initially operated on their teens. 5) There were a few cases who complained of nasal symptoms. 6) Rhinogenic visual disturbances were found in one case of posterior ethmoid sinus and in two cases of sphenoid sinus.
