Focal eosinophilic necrosis versus metastasis in the liver: the usefulness of two-phase dynamic CT.

Objective: The purpose of our study was to evaluate the usefulness of dual-phase dynamic CT in the differentiation of focal eosinophilic necrosis of the liver and metastasis.

Conclusion: Undetected isoattenuating lesions on arterial phase images that have an indistinct margin, a nonspherical shape, and a homogenous enhancement pattern on portal venous phase images suggest focal eosinophilic necrosis rather than metastasis. Two-phase dynamic CT was found to be useful at differentiating focal eosinophilic necrosis from metastasis.

Correction of cryptotia using an external stretching device.

An external stretching device was devised for the correction of cryptotia. A total of 27 cases of cryptotia received correction with this device. Patient age ranged from 10 to 40 years.

The tumbling concha-cartilage flap for correction of lop ear.

This article presents a new surgical method that uses tumbling concha-cartilage flaps to correct lop ears. Through a posterior or anterior auricular skin incision, a rectangular or T-shaped cartilage flap is elevated from the concha and tumbled backward. After passing under the postauricular skin, the flap's tip is fixed to the lidded helix or scapha.

Congenital upper auricular detachment.

A rare case of unilateral congenital ear deformity has been presented. The deformity is characterized by detachment and posterior rotation of the right upper auricle in an otherwise grossly normal auricle. We believe that this deformity may be related to defective mesenchymal fusion or accretion between the auricular hillocks of the hyoid and mandibular arches.

A single-stage two-flap method for reconstruction of partial auricular defect.

Two flaps, consisting of a postauricular skin flap and a mastoid fascial flap, were used for coverage of both sides of a grafted framework in one stage for repair of one-fourth to half auricular composite defect after trauma or inflammation. The method was safe, and the postauricular donor scar was minimal. Additionally, it was beneficial in restoring similar ear shape and size with a natural cartilage convolution.
