Study Notes

Maxillary Sinus and Nasal Cavity

The nasal cavity is connected to the maxillary sinus via the middle meatus.
Minor perforation of the nasal floor often does not lead to complications.
Validate the permeability of the maxillary sinus ostium prior to surgical procedures.

Tuberosity and Pterygopalatine Region

Utilize the tuberosity for implant placement to avoid complications in the sinus region.

Surgical Anatomy Considerations

The inferior alveolar nerve poses a high risk during surgery.
Injury to this nerve in the mandibular canal or during osteotomy can lead to permanent paresthesia.
Key surgical advantages include ensuring blood supply, sufficient visualization, accessibility, and the option to modify to a three-sided flap or increase incision length.

Absorption Mechanisms in Surgery

Absorption of materials occurs through hydrolysis or proteolytic enzymatic degradation, depending on the type used.
Surgical materials can be categorized into monofilament and multifilament groups.
