Example Sentences:
(1) Unfortunately, both the malleus and the stapes have to be in good position to use this type of reconstruction making it much less common than other forms of ossiculoplasty.
(2) These complications are of much higher frequency than after tympanoplasty with autograft, and indications for tympano-ossicular homografts are now limited to total tympanic destruction with absence of handle of malleus.
(3) In our series of 31 patients, it was found that severe conductive hearing loss, abundant pale granulations, and denuded malleus handle are constant findings and, in our opinion, are significant clinical features of the pathology.
(4) The observed pattern of development in nonirradiated specimens was the following: hypertrophy of the rostral process and endochondral-type ossification, fibrous atrophy in the midsection, and mineralization of the malleus and incus.
(5) The position, displacement and phase angle of the rotation axis of the ossicles was calculated based on the displacement and phase angle of the umbo, malleus head and lenticular process.
(6) The reshaped incus is repositioned between the malleus handle and oval window when the stapes is fixed and there also exists a lateral ossicular chain defect.
(7) The malleus exhibits a handle separated from its head and keeping a persistant relationship with the tubotympanic recess.
(8) The position of the normal-shaped mobile stapes was just medial, and not posteromedial, to the malleus.
(9) This paper presents the authors' experiences with one method of reconstruction of the tympanic membrane when it is totally absent or when there is a fixed, retracted, defective, or absent malleus.
(10) pseudomallei only, and with it, it is possible to resolve the immunological problem of distinguishing diagnosis between Malleus and Melioidosis.
(11) At high levels, the attachment is less intimate, most of the fibers appearing to pass lateral to the malleus handle.
(12) Temporal fascia placed medially to the tympanic remnants with the malleus handle exteriorized has been used successfully in over 1,200 tympanoplasties with adequate conization of the drumhead produced in most cases.
(13) All points on the tympanic membrane vibrate in phase with the malleus up to a frequency of 1 kHz.
(14) A review of 62 cases of blockage of head of malleus showed that apart from secondary lesions (post-traumatic, postoperative, postinfectious), primary blockades were a definite entity.
(15) Measurements of tympanic membrane surface area; depth of the tympanic membrane cone; the lengths of the malleus and incus long processes; and stapes footplate, annular space, and oval window areas were obtained using video micrographs and computer digitization techniques.
(16) These procedures, short and long "L-shaped" assemblies, used for patients without a malleus, resulted in a mean 27 dB bone-air gap postoperatively.
(17) Thus, disarticulation of ossicles can be localized precisely, and fixation of the head of the malleus can be differentiated from stapes fixation.
(18) However, conventional atticotomy was not able to achieve improvement in the mobility of the ossicles because the mobility is usually severely restricted at the malleus.
(19) We report on a 5-year experience with 44 patients (1980-1985) with incus interposition using a modelled or sculptured incus, either autograft or homograft, to correct ossicular discontinuity when a functional malleus and stapes are present.
