Abstract: Objective To evaluate the outcomes and indications of open rhinoplasty to treat congenital nasal dermoid and sinus cysts in children. Methods We retrospectively analyzed the clinical data of 4 children with congenital nasal dermoid and sinus cysts(3 males and 1 female)aged from 2 to 6 years at the time of surgery(average age: 4 years). All patients underwent open rhinoplasty approach for treatment. Postoperative follow-up was performed regularly. Follow-up parameters included recurrent lesions, incision scars, and nasal tip shape. Results Four children received an open rhinoplasty treatment. The fistulas were located between the middle part of the nasal bridge and the tip of the nose. All patients underwent preoperative CT and MRI to confirm the diagnosis and plan surgery. Intraoperative procedure using an open rhinoplasty approach for infectious lesions was performed under general anesthesia. Regular follow-up was conducted at 19-24 months after the operation. There were no reports of postoperative complications or recurrence, and follow-up examinations showed that the nasal incision scar recovered well; the shape of the nasal tip was normal in all cases. Conclusion Open rhinoplasty successfully treated congenital nasal dermoid and sinus cysts located in the lower third of the nose bridge to the tip, and the fistula path was longer than 1 cm without intracranial components. It can fully expose the lesion range while providing a perfect cosmetic outcome. It is safe in the pediatric population, with no significant effect on subsequent nasal growth during short-term follow-ups.
