Floating septum technique: easy and safe method maxillary sinus septa in sinus lifting procedure

Area of Science:

• Dentistry
• Oral Surgery
• Periodontology

Background:

• Maxillary sinus septa pose a significant risk of Schneiderian membrane perforation during sinus lift procedures.
• Perforation can lead to increased graft failure and complications like sinusitis.
• Managing palatal or small septa presents a particular challenge in sinus augmentation.

Purpose of the Study:

• To present a safe and effective method for managing maxillary sinus septa during sinus lift procedures.
• To reduce the incidence of Schneiderian membrane perforation.
• To improve outcomes of sinus floor elevation in the presence of septa.

Main Methods:

• A surgical technique involving flap elevation and creation of a bony window anterior to the septum.
• Careful elevation of the Schneiderian membrane.
• Mobilization of the septum using a thin, narrow osteotome and gentle malleting.
• Further membrane elevation behind the mobilized septum.

Main Results:

• Out of 16 cases, only one instance of small membrane perforation occurred.
• No patients experienced postoperative complications, including implant failure, infection, or maxillary sinusitis.
• The technique demonstrated high safety and efficacy in managing septa.

Conclusions:

• The described technique effectively addresses the challenge of maxillary sinus septa during sinus floor elevation.
• This method leads to a reduced rate of complications associated with sinus lift procedures.
• It offers a reliable solution for surgeons encountering septa, enhancing predictability of sinus augmentation outcomes.
