In questionable cases we may often learn the seat of the per-foration by means of the Siegle speculum. If the air in the ex-ternal meatus is rarefied, a drop of pus will often be seen, whichwill signify the place of perforation. On the other hand, when theair is condensed in the meatus, the opening may be seen for amoment as air passes through.
