  • Title: Tympanic membrane perforation in survivors of a SCUD missile explosion.
    Author: Patow CA, Bartels J, Dodd KT.
    Journal: Otolaryngol Head Neck Surg; 1994 Feb; 110(2):211-21. PubMed ID: 8108156.
    Abstract:
    On February 25, 1990, an Iraqi SCUD missile exploded inside a building housing United States military personnel in Dhahran, Kingdom of Saudi Arabia. One hundred seventy-two individuals who were near the impact site at the time of the blast were interviewed and examined to determine blast injury to the ear. Tympanic membrane (TM) perforation was used as the clinical marker for aural blast injury. Thirty-four personnel had unilateral TM perforation and 28 had bilateral TM perforation. Eighty-six sustained sufficient injury to be hospitalized. Fifty-nine of hospitalized personnel (70%) had TM perforation. Of a total of 90 TM perforations, 39% were estimated to be 25% or less of the tympanic membrane surface area, 36% were 26% to 50%, 16% were 51% to 75%, and 10% were greater than 75%. Morphology of the perforations and estimated proximity to the blast were documented. Personnel distant from the blast, in open doorways or wearing headphones, had relative protection from TM perforation. Historic nuclear blast data were used to estimate the SCUD blast waveform based on measurements of the SCUD impact crater. A mathematical model based on the estimated waveform was validated against the actual field data by comparing the proximity and incidence of TM perforations in the SCUD missile explosion.
