The most extensive reorganization the membrane that Politzer has yet noticed was in the case a young man online essay editing service who suffered from a discharge in the right ear for five years. A year ago, the only visible remains the membrane were seen near the short process the malleus. The bare handle the malleus stood free in the opening, and behind the dark mucous membrane the promontory.
Behind and above the processus brevis was seen the articulation connecting the incus and stapes.
The hearing was greatly diminished that the patient could not hear the loud tick a watch when in contact with the ear. A loud voice was heard at one foot.
A few weeks ago, Politzer found the membrane restored, with the exception a small oval opening below the end The healing process perforations begins paying someone to write a paper the exudation greyish-yellow plasma the margins the opening.
As this plasma being organized into cicatricial tissue, the opening diminishes phd dissertation writing gradually in size until obliterated, generally leaving a thin cicatrix, which sunken in and possesses a bright spot at its deepest part.
Its borders are very sharply marked. The structure such cicatrices varies. They either consist real fibrous tissue, as Politzer has noticed, a membrane void structure, but covered both sides pavement epithelium. The elastic fibres the substantia propria the membrana tympani are either altogether absent in the cicatricial tissue, or project here and there into its peripheral parts. Not seldom does one meet with new vessels winding into the outer layers the tissue, and all The functional disordei caused cicatrices the membrana tympani does not stand in any relation the size the cicatrix.
It has been noticed that large cicatrices, occupying writing help two-thirds the membrane, have caused little trouble the hearing, while smaller ones have been accompanied need help with my thesis severe deafiiess. This, course, depends the accompanying changes in the articulations the ossicula, caused the previous discharge.
Cases have, however, been noticed in which the cicatrix the direct cause deafness. This depends the elasticity and consistency the cicatricial tissue. A thin and relaxed cicatrix more likely interfere with the movements the membrana tympani, or change the tension the ossicula, in consequence its incapability resisting the pressure the outer Deafness much more serious when a cicatrix far sunken help others in need essay in that comes in contact wilh the promontory. The vibrations the membranes are thus essay writers needed considerably hindered, although the cicatrix not adherent the promontory. This clearly seen when the deafness brought such a complaint greatly ameliorated inflating air in the tympanum and thus pushing the cicatrix away. The deafness returns again as soon as the air in the tympanum has been absorbed, and the cicatrix resumed its former position. This may also the case when the cicatrix deeply sunken in without touching the custom research paper promontory. If, in such cases, has been confirmed means the catheter that no catarrhal thickening or secretion top ten essay writing services present, the relapse deafness may attributed the cicatrix itself. In a previous work, Politzer reported a number cases in which rupture thin cicatrices followed the use the catheter, and his method. In most these and similar ones observed Pagenstecher, Schwartze and Schurig, astonishing and buy research paper no plagiarism permanent amelioration was the immediate result, although the treatment previous the rupture was followed very short benefit.
