Zero defect is desirable but on occasion it is hard to accomplish in our dailylives. In medicine once it happens, it can raise a social problem. Authors directed their attentionsto an inadverdent visual disturbance caused by the paranasal sinusitis operations. Tostudy this problem, quetionnaires to Eye and ENT departments of the University Hospitals an d t he majorhospitals in nation. Obtained responses were analized. 1) Fifty-three cases of the visual disturbance were accumulated in total. Witha ccordance to their severeness, they were grouped into 3 groups; severe (total blind ness to handmovements) 66%, moderate (finger-counting to 0.1 in visual acuity) 22.6%, and mild (better than 0.1 in visual acuity) 11.3%. Eighty four percent o f the cases fell in age bracket of 10 to 30 years old. Male to female ratio was 2.4; 1 an dmales were dominant. From these figures it can be said that the visual disturb an eoccures more often in you ngmale. 2) Rate of this complication in a particular institution was analized stati stically. One such event is expected to occure during 19.2 years period. Supposeasur geonoperate

For the cleft palate baby, aged about a year, early application of the obt u r atorhasbeen practiced in our department. It was aimed to prevent abnormal phonation and to normalize their speech development. Results of fifteen babies thus treated were asfollows; 1) all obturators were well fitted and no adverse effect was encounterd. 2) seven out of 15 patients developed normal or almost normal speech without any special speech training. 3) three different kinds of the obturators were used. a) Velar-piece made of softelicon. b) Velar-piece made of Resin for snug fitting. The result of these obturators was good. c) Velar-piece made of thin board like Resin. This type of obturator was notsatisfac tory. This piece should be put in place, so that a tip of the Velar-piecegentlytouches the Passavant prominence of the posterior pharyngeal wall. 4) the application could be delayed as late as 2 years with good results. 5) A problem of whether the patient shoul keep wearing the obturator or betreatedsurgically upon satisfactory development of speech requires further investigation.
