Summary.
1. It is not uncommon that a diaphragm is formed in the throat of
leprous patients in the direction from the vel. palatin. and arc. posteri-
ores downwards and backwards into the posterior pharynx-wall,
which has its share in the formation of the membrane.
2. This divides the pharynx into two sections — the upper and posterior
(naso-phar)mx). and the lower and anterior (meso-hypopharynx).
3. There is an opening in the membrane. The confines are the edge of
the velum, the edges of the posterior arcs and a duplication of the
rnucous meml)rane from the posterior wall of the pharynx. Behind
the edge of the membrane is a small poche.
4. The size and the state of the diaphragm and the opening are ex-
ceedingly variable. Its size has sometimes not exceeded ] cm. in
diameter.
5. The diaphragm is formed especially when the arc. posteriores and
the palate are much infiitrated, particularly when there are great
ulcerations on the palate, and is probably caused by retraction of the
mucous membranes.
6. The diaphragm may cause difficulty of breathing, and also make
it difficult for the patient to swallow.
“. The uvula frequently slips forward on to the velum at the bottom.
lying there like a lump sticking to it; but then it may entirely dis-
appear, being resorbed.
8. Perforatio palati has never (on 140 patients affected by lepra tub.)
been observed, whereas perforatio septi nasi is exceedingly common.
