and C1a cholesteatoma were easily removed here.
Although tympanoplasty/atticotomy is a relatively elective operation in simple central or attic perforations/dry attic retraction pockets
without cholesteatoma, the existence of cholesteatoma requires mastoidectomy.
were found in 10 (13.0%) patients: with 9 (11.7%) in the pars tensa, 5 (6.5%) in the posterior....
ETD leads to the development of retraction pockets
in the tympanic membrane, setting the stage for the genesis of cholesteatoma, which appears to be a result of propagation of inflammatory process that has been set into motion.
This volume describes endoscopic ear surgery indications, principles, and techniques through 20 chapters on instrumentation and equipment, preparation, pitfalls, principles of surgery, embryology, middle ear anatomy, ventilation and pathophysiology of the middle ear, radiological considerations for middle ear surgery, the diagnosis and follow-up of retraction pockets
and cholesteatomas, and principles of endoscopic cadaveric ear dissection.
Arrangement is in seven chapters devoted to anatomy and physiology, anesthesia and surgical field, surgical materials, management of tympanic membrane abnormalities, and of ossicular abnormalities, and of retraction pockets
and cholesteatoma, and finally, dressing and postoperative care.
Because my eustachian tube on my right side had not been opening and closing as it should, there was a negative pressure in my middle ear and this negative pressure over time had caused my right eardrum to be sucked inward creating "retraction pockets
." The pockets were ripe with bacteria that caused many infections.
Julian Avisenis spoke on retraction pockets
of the tympanic membrane and Joe Diver on nasal and throat conditions.
Children with severe otitis media (OM) that requires multiple tube insertions are at greatest risk, because multiple perforations create more places for eardrum retraction pockets
Grundfast expressed greater concern that retraction pockets
can lead to cholesteatoma in children.
The tympanic membrane was inspected for pathology like attic and marginal perforations and retraction pockets
. Tos' classification for epitympanic and Sade's classification for pars tensa retraction pockets
