Utilizing Coronal Approach-Based Buccal Fat Pad for Frontonasal Duct Obliteration in Frontal Sinus Fracture...

Area of Science:

• Neurosurgery
• Plastic Surgery
• Otolaryngology

Background:

• Frontal sinus fractures impacting the frontonasal duct necessitate precise management to avoid mucoceles, infections, and intracranial extension.
• Frontonasal duct obliteration is crucial when preserving duct patency is not feasible during cranialization procedures.
• Current management strategies require effective solutions for complex frontal sinus fracture cases.

Purpose of the Study:

• To present a novel, minimally invasive surgical technique for frontonasal duct obliteration.
• To utilize autologous buccal fat pad for reconstruction in frontal sinus fracture repair.
• To reduce operative complexity and potential complications associated with frontal sinus fracture management.

Main Methods:

• A technical note detailing a minimally invasive approach for frontonasal duct obliteration using buccal fat pad.
• Harvesting of the buccal fat pad via a temporal extension through a standard coronal approach.
• Application of the harvested fat for duct obliteration following sinus mucosa removal and dural repair in a frontal sinus fracture case.

Main Results:

• The described technique achieved effective frontonasal duct obliteration without requiring additional incisions.
• The method demonstrated no donor site morbidity, minimized surgical duration, and eliminated the need for alloplastic materials.
• The patient experienced an uncomplicated postoperative recovery, preserving facial aesthetics.

Conclusions:

• This technique provides a straightforward, autologous, and minimally invasive option for frontonasal duct obliteration.
• It simplifies the surgical management of frontal sinus fractures, potentially decreasing operative complexity and associated risks.
• The approach offers a viable alternative for reconstruction in cases of frontal sinus fractures involving the frontonasal duct.
