An Absorbing Improvement for Space Infection Decompression: A Novel Drainage Device

Area of Science:

• Maxillofacial Surgery
• Biomedical Engineering
• Infectious Disease Management

Background:

• Facial space infections often require surgical intervention, with limited innovation in traditional decompression methods.
• While Negative Pressure Wound Therapy (NPWT) shows promise for abscesses, its application in maxillofacial surgery is limited.
• Existing treatments for Ludwig's Angina and other facial space infections have not significantly improved patient experience or reduced treatment duration.

Purpose of the Study:

• To explore existing treatments for infected facial space decompression.
• To identify barriers to adopting NPWT in maxillofacial procedures.
• To propose and analyze a novel drainage tool for facilitating NPWT in facial spaces.

Main Methods:

• A comprehensive literature review of current facial space infection treatments.
• Identification of challenges hindering NPWT implementation in maxillofacial surgery.
• Development and virtual prototyping of a novel drainage tool with a sleeved sponge and perforated tube.
• Structural analysis and parametric design study of the proposed drainage device.

Main Results:

• The literature review highlighted a need for improved NPWT adoption in maxillofacial surgery.
• Virtual prototyping and structural analysis confirmed the proposed tool's biocompatibility.
• The study validated the tool's flexural and axial stiffness against head and neck structures.

Conclusions:

• This work represents a foundational step towards developing specialized drainage tools for facial space infections.
• The proposed novel drainage tool shows potential for enabling NPWT in maxillofacial surgery.
• Further development of this tool could enhance NPWT adoption, improving treatment efficiency and patient outcomes.
