[Closing an anterior sinusal opening using lyophilized dura]

Area of Science:

• Surgical innovation in otolaryngology and maxillofacial surgery.
• Biomaterials science in reconstructive surgery.

Context:

• Maxillary sinus surgery often requires closure of the anterior opening.
• Traditional methods may have limitations in healing and complication rates.
• Need for reliable biomaterials for sinus floor reconstruction.

Purpose:

• To evaluate the efficacy of lyophilized dura for anterior maxillary sinus window closure.
• To assess postoperative outcomes and complications associated with this technique.

Summary:

• Lyophilized dura was systematically applied to close the anterior opening in 32 primary and 6 revisional maxillary sinus surgeries.
• Follow-up assessments revealed a low incidence of postoperative complaints.
• The study demonstrates the successful use of lyophilized dura in this surgical context.

Impact:

• Lyophilized dura presents a suitable and effective biomaterial for anterior maxillary sinus window closure.
• This technique may reduce postoperative morbidity in sinus surgery.
• Potential for improved patient outcomes in procedures involving the maxillary antrum.
