Further Outpatient Care

Patients should receive follow-up care as needed.



Bleeding: Serious bleeding is rare, occurring in only 1-2% of surgeries or postoperatively.

Surgical failures: In these complicated conditions, a 10% rate of failure occurs.

Wound infections: These occur in 5-10% of patients, usually as wound abscesses on the fourth postoperative day.

Silicone or polyethylene tubing complications: These complications occur in about 15% of cases and include the following: corneal abrasion, pyogenic granuloma, low-grade infection, chronic nasal irritation and congestion, epistaxis, sinusitis, and pharyngitis.

Bypass tube complications: These frequently occur in at least 40% of patients postoperatively and include tube loss or migration and tube obstruction.

Anesthesia complications: In children, these complications are more frequent due to drugs, blood loss, malignant hyperthermia, and pseudocholinesterase deficiency.



Overall prognosis is excellent. More than 90% of children with these developmental anomalies have improved subjective tearing postoperatively.
