This case of giant mucocele of the frontal sinus is reported because (1) the condition is sufficiently rare to justify the addition of another case to the literature on this subject; (2) the secondary effect, through pressure on the orbital structures causing definite disturbance of vision and the possibility of further pressure effects on the cranial contents, calls for operative relief, and (3) the technical difficulties in bringing about a cure, on account of the necessity of obliterating a cavity of such great dimensions, present an interesting surgical problem.
Such an accumulation of nonpurulent mucoid material is probably brought about by some chronic irritation of the mucosa of an exceptionally developed sinus and the obliteration of the infundibular canal. The continued increase of the mucoid material gradually causes the absorption of the bony walls of the sinus, with definite pressure effects on neighboring structures.1
