Right-sided pyriform sinus fistula in an adult.

Area of Science:

• Otolaryngology
• Head and Neck Surgery
• Pediatric Surgery

Background:

• Pyriform sinus fistula (PSF) is an uncommon congenital anomaly.
• It is a known cause of recurrent cervical abscesses, particularly in children.
• Most reported cases involve the left side of the neck.

Observation:

• This report details a rare case of a right-sided pyriform sinus fistula.
• The affected individual was an adult, contrasting with the typical pediatric demographic.
• The patient presented with symptoms indicative of a neck abscess.

Findings:

• Surgical intervention was performed for the right-sided pyriform sinus fistula.
• The surgical treatment resulted in a successful outcome for the adult patient.
• The etiology of this rare presentation was also explored.

Implications:

• This case expands the understanding of pyriform sinus fistula presentation in adults.
• It underscores the importance of considering PSF in adult neck abscesses, even on the right side.
• Successful surgical management in adults suggests a viable treatment option.
