Anatomical position of hyaluronic Acid gel following injection to the infraorbital hollows.

Purpose: To examine with histology the anatomical location of hyaluronic acid gel injected to the infraorbital hollows of cadaver specimens.

Methods: The authors dissected 5 fresh hemifacial cadaver specimens following preperiosteal injection of hyaluronic acid gel to the infraorbital hollows. Following tissue fixation, full-thickness soft tissue sections were obtained along the medial, central, and lateral lower eyelid/midface of each specimen.

Madarosis as an indicator for malignancy in eyelid margin lesions.

Purpose: The purpose of this study was to determine the sensitivity of madarosis as an indicator for malignancy in eyelid lesions affecting the lid margin.

Methods: A retrospective medical record review was completed for patients who were diagnosed with lesions affecting the eyelid margin which were suspicious for malignancy. Suspicion was determined by considering an array of factors, including lesion characteristics, Fitzpatrick score, sun exposure history, and history of skin cancer.

Closed meloplication percutaneous cable suture technique.

The aging midface is caused by a complex process of soft tissue volume loss, gravitational changes, and attenuation of the ligaments involved. This process results in a skeletonized appearance and elongation of the eyelid cheek complex and a medial and inferior descent of the malar fat pads. Standard facelifting techniques have been unsuccessful in addressing these issues.

Histologic comparison of autologous fat processing methods.

Purpose: To perform a quantitative analysis of adipocyte viability after fat processing during autologous fat transfer, comparing the processing methods of washing, centrifuging, and sedimentation.

Methods: An experimental study was conducted in which 24 fat samples were obtained after processing from 22 patients undergoing autologous fat transfer. Histologic analysis of periodic acid-Schiff-stained specimens was then performed.

Severe subcutaneous emphysema following orbital blowout fracture.

A 19-year-old man sustained a blowout fracture to the left orbital floor. Subcutaneous emphysema developed after a protracted sneezing episode. Some signs of respiratory distress ensued, and the patient was emergently intubated.
