Surgery performed by Dr. Cristobal Langdon
In this case uploaded to the online surgery app SurgSchool, Dr. Cristobal Langdon together with Dr. Antonio Veneri carried out a endoscopic dacryocystorhinostomy (DCR) in a six-year-old pediatric patient with bilateral epiphora of more than two years' duration. Persistent obstruction of the nasolacrimal duct on the left side, unresolved with dilation, prompted surgical indication.
Flapless Technique: Benefits in Pediatric Patients
During the intervention, a choice was made flapless technique, a particularly suitable choice in pediatric patients due to its lower rate of postoperative inflammatory reaction. This conservative approach significantly reduces the risk of complications and improves recovery, which is crucial in the pediatric population.
Use of Piezoelectric Technology to Create Bone Windows
The bone window was created using piezoelectric technology, an advanced tool that allows for precise and controlled osteotomy. This innovative technique avoids the use of conventional drilling, significantly reducing the risk of thermal damage to surrounding tissues and minimizing the possibility of uncontrolled bone fractures. Thanks to this technology, the procedure is safer and less traumatic, contributing to a better postoperative outcome.
Resection of the Medial Wall of the Lacrimal Sac
Resection of the medial wall of the lacrimal sac was essential to achieve a wide and effective opening, facilitating optimal communication between the lacrimal system and the nasal cavity. This maneuver improves tear drainage and is key to the long-term success of the procedure.
Placement of Silicone Probes to Maintain Patency
Finally, to ensure the patency of the tear duct and prevent the formation of synechiae or adhesions that could compromise function, highly biocompatible silicone catheters were placed. These catheters act as temporary support, keeping the canal open during the healing process and reducing the risk of recurrence.
Together, these advanced surgical techniques contribute to a minimally invasive, safe procedure with excellent results, especially in pediatric patients, positioning this methodology as a standard of care in lacrimal system surgery.
