An alternative method for fixation of soft tissue in the face, such as the medial and lateral canthus and free flaps, and for reconstruction of the nasolabial fold is presented, using the micro Mitek Anchor. The insertion of a bone anchor requires only a limited dissection, and the point of insertion can be determined accurately. These advantages are obvious when performing a canthoplasty. Using the bone anchor to fixate a free flap to the facial skeleton is an effective way to prevent sagging of the flap as a result of gravitational forces. In contrast, the use of bone anchors in facial neurofibromatosis has not been as rewarding.
BACKGROUND: A recently developed digital tonometer for transpalpebral intraocular pressure (IOP) measurement, distributed by Corneal, Inc., allows the noninvasive measurement of IOP for screening purposes. METHOD: We measured the IOP of 218 eyes in 109 patients of the Interdisciplinary Uveitis Center of the University of Heidelberg with intact corneal epithelium. IOPs were measured first with the TGDc-01 tonometer, and then by means of Goldmann tonometry. IOPs were recorded by two independent examiners. The mean of three measurements obtained with the TGDc-01 was taken, whereas only one measurement was performed with the Goldmann tonometer. RESULTS: The mean difference between the TGDc-01 and Goldmann measurements was 3.7 mmHg. The standard deviation of the differences was +/-4.06 mmHg. Thus measurements acquired with the TGDc-01 may range 4.4 mmHg above or 11.8 mmHg below the values given by Goldmann tonometry. CONCLUSION: The IOP values obtained with the TGDc-01 were in poor agreement with Goldmann tonometry. We found a higher variation as well as a bias towards lower IOP values with the TGDc-01. It is a question of clinical judgement as to how far these deviating measurements can be accepted for screening purposes. Because the IOPs obtained with the TGDc-01 are generally lower and less accurate than those obtained with the Goldmann tonometer we believe that the TGDc-01 is not a reliable tool for IOP measurement in clinical routine.
