Tympanic Membrane Perforation Repair Using Alloderm
Otolaryngology–Head and Neck Surgery, 2000BACKGROUND:Some patients lack quality autologous tissue for tympanic membrane (TM) grafting. AlloDerm (LifeCell Corp, The Woodlands, TX) is a preserved allograft that has been effective in nonotologic applications.OBJECTIVE:The goal of this study was to investigate AlloDerm in the repair of chronic TM perforations.

The mechanism of cell membrane repair
Zygote, 1999Disruption of plasma membranes is a widespread, common and normal event that occurs in many mechanically challenged tissues (McNeil & Steinhardt, 1997). After injury to the plasma membrane, rapid resealing of the membrane occurs with little loss of intracellular contents.Analysis of plasma membrane repair in the sea urchin egg and early embryos ...

Crosslinked hydrogels for tympanic membrane repair
Otolaryngology–Head and Neck Surgery, 2006PROBLEMTo provide a less expensive and more convenient protocol for the treatment of tympanic membrane perforations (TMPs).METHODSSeveral materials were prepared and compared for TMP repair including Carbylan‐SX, Gelatin‐DTPH‐PEGDA (GX), Carbylan‐S/Gelatin‐DTPH (Carbylan‐GSX) (injectable and sponge), Gelfoam, Epifilm, and crosslinked thiolated ...

Repair of Complete Tympanic Membrane Perforations
Archives of Otolaryngology - Head and Neck Surgery, 1965COMPLETE or "pantympanic" perforations denote total loss of the tympanic membrane with the exception of a rim of pars tensa left as a remnant which is actually the annulus of the pars tensa. This perforation usually excludes the pars flaccida of the drum.

Dealing with damage: Plasma membrane repair mechanisms
Biochimie, 2014Eukaryotic cells have developed repair mechanisms, which allow them to reseal their membrane in order to prevent the efflux of cytoplasmic constituents and the uncontrolled influx of calcium. After injury, the Ca(2+)-concentration gradient fulfils a dual function: it provides guidance cues for the repair machinery and directly activates the molecules ...

Technique for repair of descemet membrane detachment
American Journal of Ophthalmology, 1999To demonstrate a successful repair of an intractable Descemet membrane detachment.Case report. We used transcorneal mattress sutures to fixate Descemet membrane to the cornea in combination with intracameral air injection.This technique resulted in reattachment of Descemet membrane and a substantial visual acuity improvement after complete resolution ...

Success of tympanic membrane repair following palatoplasty
International Journal of Pediatric Otorhinolaryngology, 2019Eustachian tube dysfunction, ubiquitous in patients with cleft palate, is a known risk factor for failure of tympanic membrane (TM) repair. Age may also influence the success rate. We describe a cohort of patients with cleft palate who underwent TM repair at a tertiary academic medical center.Record query of International Classification of Diseases ...

Perineal Repair of Membranous Urethral Stricture
Urologic Clinics of North America, 1989Membranous urethral disruption secondary to pelvic fracture often results in an obliterative stricture. Most of these lesions can be repaired by a one-stage procedure provided certain maneuvers are accomplished to facilitate approximation of the bulbar to the prostatic urethra: urethral mobilization as far proximal as the suspensory ligament of the ...

Mitochondria for plasma membrane repair
Science, 2017Cell Biology Mechanical strain on cells can cause damage to the plasma membrane that must be repaired before extracellular Ca2+ influx reaches levels that trigger cell death. Horn et al. found that mitochondria mediated the repair of plasma membrane injuries in mouse muscle cells and human nonmuscle cells (see the Focus by Cooper).
