It is not an infrequent experience to see localized subcutaneous hemorrhage or congestion in the eyelid, conjunctiva or neck not always ipsilaterally but sometimes contralaterally after an oto-rhinolaryngological operation, especially after a paranasal sinus operation, in spite of disapproval of abnormal observation, such as hemorrhagic diathesis etc.The authors now report those on account of having experience of the same several cases as above mentioned ones, and are inclined to trace their origins.Autonomic nervous function of these patients was situated on very unstable or unbalanced condition, especially circumstances of parasympathetic function was conspicuously excitable.This hemorrhagic phenomenon as a result of E. Saitos experimental study on the rat, is concluded as follows: Namely irritation caused by various excessive stimulations from operation or its injury, chiefly through the agency of autonomic nervous fibers and abnormal constitutional factor, i. e. remarkable unbalanced condition of autonomic nervous function, bring on vascular disturbance with edema, vasodilatation, stagnation of blood cells and hemorrhage.These facts have included the authors to interprete the hemorrhagic lesion in the eyelid as a manifestation of the Reillys phenomenon.
