Summary

Minimizing visible scarring after external dacryocystorhinostomy (Ext-DCR) involves various surgical and post-operative strategies. While no single technique is universally accepted, tailored approaches show promise for improved aesthetic outcomes.

Area of Science:

Ophthalmology
Plastic Surgery
Dermatology

Background:

External dacryocystorhinostomy (Ext-DCR) is a surgical procedure to restore tear drainage.
Visible scarring is a common concern for patients undergoing Ext-DCR.

Purpose of the Study:

To review existing literature on surgical modifications and post-operative strategies for minimizing visible scarring after Ext-DCR.
To identify techniques associated with improved aesthetic outcomes in Ext-DCR.

Main Methods:

Comprehensive literature search of major medical databases (PubMed, Medline, Embase, Cochrane Central, CINAHL).
Inclusion criteria focused on studies assessing incision techniques, closure methods, post-operative care, and scar visibility outcomes.
Analysis of 40 studies involving 3750 procedures.

Keywords:

Published on: June 20, 2018

Main Results:

Visible scarring prevalence varied (0-50%), with most studies reporting <10%.
Techniques linked to better aesthetic results include alternative/minimal incision designs and sutureless closures.
Patient-specific tailoring of techniques based on skin type and concerns showed improved outcomes.

Conclusions:

Surgical modifications and post-operative strategies can reduce visible scarring after Ext-DCR.
Personalized approaches to incision and closure are beneficial.
Standardized scar assessment is needed for future research and optimizing best practices.
