In a series of twenty-nine schizophrenic patients, Kline and Tenney compared the results after topectomy or lobotomy with body type. They felt that there was a decidedly better prognosis when either operation was performed on a mesomorph rather than on a nonmesomorph. In their series the prognosis for a favorable outcome in a nonmesomorph was less than one in ten whereas four out of five mesomorphs obtained good results.
