It is generally sessile and solitary, and may grow into the interior of the skull, into the frontal sinus, into the cavity of the orbit or nose, or may fill up the external auditory meatus, causing most unsightly deformity and interference with sight, breathing, and hearing.
If a woman who has never been pregnant, standing in the erect position before commencing the act of urination presses apart the labia minora with index and middle fingers the stream will be projected forward so as to fall usually at a considerable distance in front of a vertical line from the meatus; if when the act is half completed the fingers are removed, the labia close together and the stream, though maintained at a constant pressure, at once changes its character and direction.
The varieties of the disturbances of the functions of the ear range from tinnitus aurium to congestion causing complete deafness. The gastro-intestinal and genito-urinary tracts are especially disposed to untoward action by quinin. There is a case recorded in which, after the slightest dose of quinin, tingling and burning at the meatus urinarius were experienced.
There was no loss of semen, but after the paroxysms a small quantity of glairy mucus escaped from the meatus. The rigidity was remarkable, simulating the spasms of tetanus. No language could adequately describe the suffering of the patient.
The bladder was under perfect control, the urine flowing over a channel on the exterior of the scrotum, extending 18 inches from the meatus. Despite his infirmity this patient had perfect sexual desire, and occasional erections and emissions. A very interesting operation was performed with a good recovery.
In one case 22 small stones were removed, and in the other a single calculus weighing one ounce 110 grains. Congenital phimosis is said to be very common among the natives of Solomon Islands. In September, 1695, Bernard removed two stones from the meatus urinarius of a man, after a lodgment of twenty years. Block mentions a similar case, in which the lodgment had lasted twenty-eight years.
In the orbit it displaces the eyeball; in the nasal fossæ and in the external auditory meatus it causes obstruction, which may be attended with ulceration and discharge. In the skull it may project from the outer table, forming a smooth rounded swelling, or it may project from the inner table and press upon the brain.
The female cells or ova are formed in the ovaries and discharged into the Fallopian tubes, along which they travel into the uterus. This diagram shows the male urethra or passage down the male organ as somewhat distended. Generally, the walls of this passage are collapsed together. The seminal fluid is discharged down the urethra and emitted at orifice marked "meatus."
This is formed into a part of the organ of hearing; from it are developed the external meatus, the tympanic cavity, and the Eustachian tube. We have already considered these remarkable structures, and need only point here to the interesting fact that our middle and external ear is a modified inheritance from the fishes.
The entire skull was laid bare from the margin of the eyelids to the neck. The nasal bones were uncovered and broken, exposing the superior nasal meatus. The skin of the eyelids was removed from within three mm. of their edges.
