Disease relevance of Oval Window

• Recurrent meningitis secondary to idiopathic oval window CSF leak [1].
• Any patient with a history of diving and subsequent sensorineural hearing loss within 72 hours should be suspected of having a round or oval window perilymphatic fistula and surgical exploration and closure of the fistula should be undertaken [2].
• Obliterative otosclerosis has been a challenge since the advent of stapes surgery. "Drill-out" procedures have had a generally poorer prognosis than conventional stapes surgery because of excessive bleeding, acoustic trauma from the burr, and reclosure of the oval window by otosclerosis [3].
• 10. The piston operation is highly recommended as a safe and suitable method of alleviating, in the long-term, the conductive hearing loss of patients with obliterative otosclerosis of the oval window [4].

High impact information on Oval Window

• My results also suggest a Hoxa-2-mediated patterning of the otic capsule in the region where the oval window is located [5].
• In two patients, coronal CT scans showed extension to the oval window in one and through it in the other [6].
• Deafening was produced by surgical removal of the incus and stapes ossicles, aspiration of the cochlear perilymph, and kanamycin injection into the oval window [7].
• CONCLUSION: Congenital absence of the oval window can be diagnosed on CT studies [8].
• An oval window of polyvinyl chloride film was sutured in place in the skin over the wound [9].

Anatomical context of Oval Window

• METHODS: Using a variety of settings, a Sharplan 150 XJ Laser and a Contour model Erbium:YAG laser were applied to the oval window of human temporal bones [10].
• New celluluar bone which simulated otosclerosis filled the anterior oval window niche and was continuous with the middle ear surface of the footplate fragments [11].
• Gentamicin then penetrates the round and oval windows, where it influences inner ear function [12].
• INTERVENTION: Analysis of perioperative and follow-up audiograms with associated operative findings, including obliterative otosclerosis and solid footplates, dehiscent or overhanging facial nerve, narrow oval window niche, promontory overhang, and ossicular fixation or malformation [13].
• Subsequent tympanotomy confirmed the site of the CSF leak as the oval window in the majority of cases; packing the vestibule with muscle halted further attacks in these patients [14].

Associations of Oval Window with chemical compounds

• The oval window niche was filled with either 1 percent sodium hyaluronate or 0.9 percent NaCl [15].
• Then, DEM samples were mounted in oval windows equidistant between Ag/AgCl agar electrodes in exposure chambers containing serum-free medium [16].
• Subsequent use of fluorescein intrathecally not only helped to confirm the diagnosis but was very useful at surgery in locating the leak in the dura of the oval window of the ear [17].

Gene context of Oval Window

• Otosclerosis involved the left and right oval window niches (bilateral stapedectomy had been performed) [18].
• The opercularis system (OPS) of amphibians consists of an opercularis muscle that connects the shoulder girdle skeleton to the operculum, a movable element in the oval window of the otic capsule [19].
