External auditory canal stenting utilizing a useful rolled, tapered silastic sheet (RTSS) post middle ear surgery

Area of Science:

• Otolaryngology
• Surgical Innovation

Background:

• Conventional postoperative aural packing presents several demerits.
• There is a need for improved methods for external auditory canal management after middle ear surgery.

Purpose of the Study:

• To develop and evaluate a novel protocol for postoperative stenting of the external auditory canal using a rolled, tapered silastic sheet (RTSS).
• To assess the efficacy and reliability of RTSS for enabling transcanal drainage and allowing visual inspection post-middle ear surgery.

Main Methods:

• The study involved 24 surgeries on 21 patients undergoing tympanoplasty with a postaural incision.
• A 0.3mm thickness rolled, tapered silastic sheet (RTSS) with antibiotic ointment was used for external auditory canal packing.
• RTSS packing was removed 5-10 days postoperatively.

Main Results:

• Successful postoperative ear packing was achieved in 23 out of 24 surgeries (20 patients).
• The tympanic membrane and external auditory meatus were observable immediately post-stenting and during follow-up.
• Secretions were easily suctioned during surgeries with ventilation tube insertion; no harmful effects were observed.

Conclusions:

• The developed RTSS protocol is a useful and reliable method for postoperative external auditory canal stenting.
• RTSS offers advantages over conventional packing methods, including facilitated drainage and continuous visual access.
