We present a case of a male patient who presented with facial asymmetry and epiphora. A diagnosis of imploding antrum syndrome secondary to sarcoidosis was made on the basis of characteristic computerised tomography features, elevated serum ACE and histopathological findings. We suggest that chronic inflammation within the sinus cavities, due to sarcoid, had caused osteolysis of the sinus walls, subsequently leading to the typical presentation of imploding antrum syndrome.
