Indications for Obliteration and Closed Mastoid Operations

Archives of Otolaryngology - Head and Neck Surgery, 1969
The increased interest in postoperative care and the avoidance of an open cavity in mastoid and tympanoplasty surgery is a natural development in the progress of otologic surgery. The control of the pathological process, maintenance or improvement of hearing to an adequate level, and a healed ear with a minimum amount of morbidity and postoperative ...

Mastoid Obliteration with Autologous Costal Cartilage

Otolaryngology–Head and Neck Surgery, 2012
ObjectiveAutologous cartilage such as conchal cartilage has been commonly used as an obliteration material of the mastoid, however sufficient amount could not be harvested. We evaluate the use of autologous costal cartilage for obliteration of mastoid cavity after canal wall down mastoidectomy.MethodRetrospective review of the patients who underwent ...

Evaluation of mastoid obliteration surgery.

The American journal of otology, 1996
The anatomic results of mastoid obliteration surgery on 54 ears during the past 10 years were analyzed, and the comparative utility of several materials for obliteration was evaluated. Thirty-three ears had primary chronic otitis media with or without cholesteatoma (group 1), and 21 ears had old open mastoid with intractable chronic discharge due to ...

Mastoid and Epitympanic Bony Obliteration in Pediatric Cholesteatoma

Otology & Neurotology, 2008
The primary goal of cholesteatoma surgery is complete eradication of the disease. To lower the recurrence rate in the pediatric population in canal wall up techniques and to avoid the disadvantages of canal wall down techniques, the bony obliteration technique with epitympanic and mastoid obliteration has been developed. The objective of this study was

[Mastoid obliteration in open cavities].

Acta otorrinolaringologica espanola, 1998
The obliteration of a large or irregular mastoidectomy cavities with hard-to-control areas is a common problem for ENT surgeons. Numerous obliteration techniques have been proposed in the last 50 years. We report our experience of obliteration of mastoid cavities in 74 ears using autogenous mastoid cortical bone chips and rib cartilage.

Use of porous ceramics to obliterate mastoid cavities

Journal of Biomedical Materials Research, 1973
AbstractThe mastoid process of the temporal bone can become infected with possible serious complications. If the infection does not respond to antibiotics, the infected area must be surgically removed, with the result that a cavity is formed. This cavity must be obliterated before the soft tissues can be closed over the site.Many biological tissues ...

Mastoid Obliteration: Histopathological Study of Three Temporal Bones

Archives of Otolaryngology - Head and Neck Surgery, 1975
Three temporal bones were serially sectioned to study the postoperative fate of the meatally based postauricular musculoperiosteal flap. In all three ears, the flap sealed off the middle ear effectively from the mastoid cavity and in one, with resected canal wall, formed a new soft posterior wall with good meatus. All flaps contained viable muscle, fat,

Mastoid obliteration using platelet-rich plasma

Folia Otorhinolaryngologiae et Pathologiae Respiratoriae
Background: Research and development of new surgical treatments for patients with chronic purulent otitis media are actively carried out in otosurgery as today there is no single generally accepted treatment. This is an urgent task in pediatric practice as hearing loss in children can lead to irreversible consequences for their development.
