A “step-by-step” case of Dr. Pavel Dolezal
Pediatric nasal meningoencephalocele surgery is a surgical challenge that requires precision and experience. In this video uploaded to the surgery app SurgSchool, we explore a real case carried out by the Dr. Pavel Dolezal, President of the Slovak Society of Otolaryngology from 2014 to 2024 and Head of the University Department of Otolaryngology and Head and Neck Surgery at St. Michael's Hospital in Bratislava, who led this procedure on a six-year-old girl. In addition to being a leader in his field, Dr. Dolezal is recognized for his skill in complex interventions such as this one, where interdisciplinary collaboration and cutting-edge technology are essential.
What is a Nasal Meningoencephalocele? Un nasal meningoencephalocele It is a herniation of brain tissue and the meninges (the membrane that covers the brain) into the nasal cavity. This rare condition occurs in some pediatric patients and requires delicate surgical treatment, as it involves both repairing the brain structure and restoring the anatomical functions of the skull and nose.
The Surgical Technique of Dr. Pavel Dolezal
Step 1: Access and Initial Evaluation
The intervention begins with access to the left nasal cavity. Here, the team uses a suction tube to approach the lesion, which is located behind the nasal septum and the middle turbinateThe surface of the meningoencephalocele, which has dilated vessels, is coagulated preventively to avoid complications.
Step 2: Resection and Exposure of Neural Tissue
Once the lesion is identified, the meningoencephalocele is carefully resected with a microdebriderAs the resection progresses, the white neural tissue, confirming the presence of the brain in the lesion. This step is crucial to ensure complete removal without compromising adjacent areas.
Step 3: Identification of the Defect and Repair of the Dura Mater
A is located defect at the base of the skull with pulsating dura mater, indicating that the membrane surrounding the brain is exposed. To repair this defect, the team performs a duraplasty using a perichondrium graft, which is placed intracranially under the dura mater and fixed with biological glueThis procedure ensures protection of brain structures while promoting healing.
Step 4: Extracranial Reinforcement and Final Closure
As a reinforcement measure, Dr. Dolezal adds a second layer of perichondrium in the extracranial part, which is also secured with biological glue. Finally, to reinforce the integrity of the repair, bone fragments of the middle turbinate, sealing the area with more glue to ensure a stable and well-protected structure.
Step 5: Nasal Packing and Postoperative Recovery
The procedure concludes with a nasal congestion, which is maintained for two days to prevent infection and promote recovery. During the postoperative period, the patient showed satisfactory progress, with no neurological deficit, and was discharged within the same week of surgery.
