At the Triological Society section meeting of the combined otolaryngology spring meeting in Palm Beach, Fla, Dr Zinreich and colleages, The Johns Hopkins University Medical Center, Baltimore, have studied 212 patients utilizing three-dimensional reconstructions from two-dimensional computed tomographic scans and 212 patients with various head and neck pathologic states, including congenital anomalies of the calvarium, maxillofacial trauma, laryngeal trauma and tumors, sinusitis, and even cochlear implantation. The techniques used are not new, nor were their applications. The three-dimensional reconstructions are interesting to view, but seldom provide any new detail that is not already apparent on the better images produced by conventional computed tomography and/or plain films. The only exception to the foregoing were some examples of delayed reconstruction of the ramus and body of the mandible, which were performed using mirror image and fusion techniques to produce an accurate whole mandible from a remaining hemimandible.
