I wish to submit to the profession a bilateral self-retaining nasal speculum for use in septum resection operations. I have tested it by many years' usage and found it to be an extremely useful instrument.
The speculum is made of spring wire. It consists of two individual specula, a right and a left, that are connected above to form one unit, as illustrated in Figure 1. H in Figure 1 is a hook attached to the upper extremity of the instrument, and the upper end of the hook is hooked over a bandage that is tied across the patient's forehead. Figure 2 shows the speculum in use on a patient and gives a good idea of the manner in which it is inserted into the nostrils and suspended from the band across the patient's forehead. Figure 2 also shows the exposure that it gives. When properly made and inserted, the instrument can stay in place in spite of cosiderable intranasal instrumentation.
