A new method using xenogeneicacellular dermal matrix in the reconstruction of lacrimal drainage.

Chen L, Gong B, Wu Z, Jetton J, Chen R, Qu C - Br J Ophthalmol (2014)

Bottom Line: Patency was confirmed by pressing in the area of the lacrimal sac and visualising air bubbles in the nasal cavity.Five tear ducts proved to be effective through irrigation testing and epiphora symptoms were alleviated in all cases.The newly reconstructed lacrimal duct, formed by the shift of autogenous conjunctival petal and the attachment of acellular dermal matrix, was successful in all five cases and suggests a new solution for the complex lacrimal duct lesion and congenital anomalies of the lacrimal duct.

The intraoperative pictures of the 9-year-old boy. There is a tunnel made from lacrimal caruncle through lacrimal sac area (A). The conjunctiva was harvested from inferior fornix (B). The conjunctiva was attached onto the oral biofilm (C). The oral biofilm was rolled into a tube shape with the conjunctiva being the internal lining (D). The newly-built duct was placed into the tunnel of lacrimal duct and fixed, with one end fixed onto the lacrimal caruncle and the other end fixed onto the nasal mucosa within the bony window (E).

Mentions: A skin incision was placed in the medial canthal region. A subcutaneous tunnel was created between the lacrimal fossa and the lacrimal caruncle (figure 2A).
