Access to the maxillary sinus using a bone flap on a mucosal pedicle: preliminary report

The management of complications following displacement of oral implants in the paranasal sinuses: a multicenter clinical report and proposed treatment protocols

“…These displaced foreign bodies should be removed as soon as possible to prevent such complications 10,12,13,15,18,19,20,27 . Two main treatment modalities have been proposed for the removal of displaced implants in the sinuses and to treat the associated infectious complications: an intraoral approach with the creation of a bony window in the anterior-lateral wall of the maxillary sinus 2,11,18,19,20 ; and a transnasal approach with functional endoscopic sinus surgery (FESS) 12,13,15,28,27 . FESS allows removal of displaced implants, treatment of paranasal sinusitis and recreation of adequate patency of the natural maxillary ostium with a minimally invasive procedure, but it cannot close oro-antral communications.…”

Retrieval of Root Fragment in Maxillary Sinus Via Anterolateral Wall of the Sinus to Preserve Alveolar Bone

“…Nevertheless, this technique requires specific training and equipment, making it difficult for dentists to operate on patients, and is of a limited value if there is a need to remove odontogenic lesions or teeth. 7 With the increasingly frequent use of dental implants to replace nonrestorable teeth, preservation of the existing alveolus is essential to maintain adequate bone volume for placement and stabilization of the implants. 13 The surgical technique described in this literature harvests a bone lid from anterolateral wall of the maxillary sinus, which insures optimal vision and makes it convenient to remove teeth and odontogenic lesions.…”

“…5,6 Marsupialization and endoscopic surgery for DCs in the maxillary sinus are reported in literature. 7,8 Marsupialization has the disadvantages of being unable to remove all the lesions and to avoid relapses after surgery. Also reported were endoscopically assisted Caldwell-Luc procedures for removal of a foreign body from the maxillary sinus.…”

“…It is also of limited value if there is a need to remove odontogenic lesions or teeth. 7 The aim of this study was to present a functional surgery to remove root fragments displaced into maxillary sinus using piezosurgery, associated with the use of endoscopy if necessary, and maintain the integrity of the lateral wall of the maxillary sinus using a replaceable bony window after their removal if the bone lid was large, which not only preserved the alveolar bone but also had minimal complications.…”

Surgical Alternative in Sinus Lift Reoperation

“…Although the Caldwell-Luc technique [11] has been indicated to remove foreign bodies presented into the maxillary sinus, this procedure causes extensive damage in the Schneiderian membrane and compromises future bone regeneration [12].…”
