Assessment of Bony Nasolacrimal Parameters Among Asians

Abstract

There is no significant difference in nasolacrimal duct diameter among ethnic groups, which may predispose one to nasolacrimal duct obstruction. But, this is significantly associated with inter-frontozygomatic suture distance, suggesting that a wider face is associated with wider nasolacrimal duct diameter. An acute frontonasal angle predicts a thicker anterior lacrimal crest for surgical preparation during dacryocystorhinostomy.

Adjustable Medial Epicanthoplasty Using a Rotational Flap for Epiblepharon Repair

“…2,4,11 This is thought to be due to the fact that the dense fibrous tissue pulls the anterior lamella of the eyelids medially and superiorly in the lower eyelid and medially and inferiorly in the upper eyelid, thus making a vector of the cilia to fall dorsally. 12,13,14 In addition, the medial portion of the tarsus approach to the MCT, where is not enough base for anchoring the rotational suture, which may result in the under-correction of the epiblepharon. Thus, epicanthoplasty is not always but considered essential for successful epiblepharon surgery, which can be vital for visual development, especially in younger children.…”

“…To reduce the traction of the epicanthal fold on the eyelids, disconnecting the dense fibrous tissue from the anterior lamella of the eyelids is essential. 12,13,14 After this dissociation, a common problem that arises is the amount of the skin on the epicanthal fold varies depending on its width and length. This often leads to epicanthoplasty failure.…”

“…The concurrence of both epi-blepharon and epicanthal folds is well known as is the tendency of epiblepahron to recur or be under-corrected following epiblepharon surgery alone co 2, m 4,1 p 1 ared to epiblepharon surgery combined with epicanthoplasty 2,4,11 . This is thought to be due to the fact that the dense fibrous tissue pulls the anterior lamella of the eyelids medially and superiorly in the lower eyelid and medially and inferiorly in the upper eyelid, thus making a vector of the cilia to fall dorsally 12,13,14 . In addition, the medial portion of the tarsus approach to the MCT, where is not enough base for anchoring the rotational suture, which may result in the under-correction of the epiblepharon.…”

“…The first feature is that the design is adjustable until the completion of the skin closure, and the second feature is that the design provides the advantage of concealing and minimizing scar formation. To reduce the traction of the epicanthal fold on the eyelids, disconnecting the dense fibrous tissue from the anterior lamella of the eyelids is essential 12,13,14 . After this dissociation, a common problem that arises is the amount of the skin on the epicanthal fold varies depending on its width and length.…”
