ABSTRACT
Objective To investigate a new method and to observe the clinical effect of repairing the lower eyelid ectropion assisted with the subcutaneous pedicle flap from temporal region. Methods Since 2007, 24 patients with lower eyelid ectropion were treated with the subcutaneous pedicle flap from temporal region which was the donor area without hairs, including 8 cases of scar infection, 6 cases of trauma, and 10 cases of tumor removal. Among the 24 cases of the flap, the maximum area was 5. 5 cm× 1. 5 cm,and the minimum was 4. 0 cm × 1.0 cm. Results All patients were followed up for 6 months to 3 years.All flaps survived completely with excellent texture and appearance. The donor site was hidden and no obvious malformation of the donor site was observed. Conclusions Because the blood supply of flap is reliable and the incision in the donor site is hidden, the subcutaneous pedicle flap from temporal region pedicled with arterial network of the outer canthus is an ideal donor site for repairing the lower eyelid ectropion with full thickness defects.
ABSTRACT
OBJECTIVE: The purposes of this study were to evaluate the reproducibility and reliability of head posture obtained by registering outer canthus as a soft tissue landmark with the Outer Canthus Indicator (OCI). METHODS: Twenty-one adults with normal facial morphology were enrolled in this study (mean age 27.5 +/- 1.72 years). To register initial head posture, height of the outer canthus from the ear rod plane was measured using OCI. Head posture was reproduced by moving the head upwards and downwards until the outer canthus was in a straight line with the indicator set at a registered height. After the head posture is reproduced by two operators after two days, lateral photographs were taken. Computerized photometric analyses of the photographs were performed. RESULTS: The head rotations around the transverse axis were 0.69 +/- 0.43degrees, 0.98 +/- 0.65degrees from each of the two operators. Standard errors were 0.09degrees and 0.14degrees each, which were similar to results from past research findings. There were no significant differences between the data from the two operators (p > 0.05). There were no correlations between the head rotation around the horizontal and vertical axes (p > 0.05). CONCLUSIONS: The present study suggests that OCI-registered head posture may minimize errors from vertical head rotation in cephalometry and photometry.
