Extended External Rhinoplasty Approach For Nasal Dermoids With Intracranial Extension

Area of Science:

• Otolaryngology
• Pediatric Surgery
• Neurosurgery

Background:

• Nasal dermoid cysts with intracranial extension are rare congenital malformations.
• Surgical management requires careful planning to ensure complete removal and minimize complications.

Observation:

• A 3-year-old patient presented with a nasal dermoid cyst extending into the intracranial space.
• An extended external rhinoplasty approach utilizing bilateral marginal and alar base incisions was employed.

Findings:

• The surgical approach provided adequate exposure for cyst removal.
• It facilitated necessary nasal bone osteotomies and access to the skull base.
• The procedure resulted in a cosmetically acceptable scar.

Implications:

• This technique offers a viable surgical option for complex pediatric nasal dermoid cysts.
• It demonstrates the feasibility of achieving complete resection with good aesthetic results.
• The approach may be beneficial for similar congenital sinonasal tumors.
