Disease relevance of Mastoid


High impact information on Mastoid

  • Although magnetic resonance (MR) imaging routinely is used to evaluate the facial nerve, the conventional axial, coronal, and sagittal planes are not optimal for demonstrating the tympanic and mastoid portions of the nerve [6].
  • In the third case, an expansile mastoid cholesterol cyst exhibited medium signal intensity on T1-weighted images, with only a small hyperintense area and a hypointense area located in the cystic wall [7].
  • High-resolution computed tomography of the middle ear and mastoid. Part III: Surgically altered anatomy and pathology [8].
  • High-resolution computed tomography of the middle ear and mastoid. Part II: Tubotympanic disease [9].
  • METHODS: Exposed frontal sinus, mastoid air cells, and frontal base defects caused by fracture are covered with periosteum or fascia and plugged with a trimmed hydroxylapatite ceramic button [10].

Associations of Mastoid with chemical compounds

  • Potentials were recorded from Cz, C3, and C4 referenced to linked mastoid electrodes [23].
  • By contrast, the amplitude of the subcortical response as recorded in vertex to linked mastoid and vertex to upper cervical spine derivations was not significantly altered by changing concentrations of isoflurane or N2O [24].
  • Auditory evoked potentials were recorded in the awake state and during anesthesia with end-expiratory steady-state concentrations of 0.5, 1.0, 1.5, and 2.0 vol% of sevoflurane on vertex (positive) and mastoids on both sides (negative) [25].
  • Following therapy with vinblastine, prednisone, methotrexate, and cyclophosphamide, the lesions healed but disease recurred in the mastoid and was successfully treated with vinblastine alone [26].
  • The bone-anchored hearing aid is coupled to a percutaneous titanium implant, which is placed in the mastoid process in two surgical stages [27].

Gene context of Mastoid

  • This difference was not significant (chi = 0.17, P =.68) CONCLUSION: For the treatment of posterior canal BPPV, concurrent mastoid oscillation with CRP does not significantly alter the short-term outcome [28].
  • CD68-positive cells were scattered only in the effusion of mastoid air cells [29].
  • From Old to New World Colonial samples there is a noticeable skull change (and a greater Old World to Modern contrast) but White Colonial to Modern shows strong continuity surprisingly, the key changes being increasing head height, and retraction of face with increasing nose projection, and longer mastoids, resulting from selection and mixture [30].
  • In gracile australopithecines and subsequently living hominids, trends towards increased frequencies of mastoid and (later) parietal emissary foramina coincide with a trend towards decreased frequencies of an enlarged O/M sinus system and multiple hypoglossal canals [31].
  • Drill-generated sensorineural hearing loss following mastoid surgery [32].

Analytical, diagnostic and therapeutic context of Mastoid

  • EEG and CNV components (post S1, N1, P2, P3; early CNV; N1200; late CNV; CNV resolution) were recorded from Fz, C3, Cz, C4, P3, Pz, and P4 referenced to linked mastoid electrodes [33].
  • Cz, C3 and C4 referenced to linked mastoids and right EOG were recorded [34].
  • Cotton swabs soaked in an aqueous isotonic lithium chloride solution were placed over the eyes and mastoids of the dogs, and connected to the electrosleep apparatus [35].
  • This is an 8-year follow-up of a group of 214 patients who underwent surgical insertion of titanium implants in the mastoid process for the retention of bone-anchored hearing aids and auricular prostheses [36].
  • In this communication, we report an 83% healing rate after myringoplasty that included mastoidectomy with posterior and anterior tympanotomy in a selected group of patients with poor tubal function and small mastoids [37].
