Insights
Sphenochoanal polyps (SCPs) in children originate in the sphenoid sinus and cause nasal blockage. Surgical removal and sinus ostium enlargement are key treatments to prevent recurrence.
Area of Science:
- Otorhinolaryngology
- Pediatric Surgery
Background:
- Sphenochoanal polyps (SCPs) are rare sinonasal tumors in children.
- These polyps arise within the sphenoid sinus and extend into the choana.
Observation:
- Clinical presentation includes nasal obstruction and headaches.
- Endoscopic examination identifies choanal polyps; CT scans confirm sphenoid origin.
- Maxillary sinus opacities may be present with middle meatus obstruction.
Findings:
- SCPs are histologically indistinguishable from antrochoanal polyps (ACPs).
- Diagnosis relies on imaging (CT scan) to determine the sphenoid sinus origin.
Implications:
- Surgical excision combined with sphenoid sinus ostium enlargement is the recommended treatment.
- Lack of awareness regarding SCPs can lead to inadequate treatment and polyp recurrence.
Abstract:
Two cases of sphenochoanal polyp (SCP) in children are reported. SCPs originate in the sphenoid sinus cavity, and extend into the choanal via the ostium. Symptoms associated with the syndrome include nasal blockage and headaches. Endoscopical examination reveals the presence of a choanal polyp, and the sphenoid origin of the polyp can be determined by CT scan. In cases where the middle meatus is obstructed, an opacity of the maxillary sinus is often observed. SCPs cannot be distinguished from antrochoanal polyp (ACP) by histological means. The treatment of the SCPs involves surgical removal and enlargement of the sphenoid sinus ostium. Ignorance surrounding the existence and the treatment of this syndrome may result in insufficient treatment and the consequent recurrence of the disorder.
