Biomaterials for Drugs Nose-Brain Transport: A New Therapeutic Approach for Neurological Diseases.

Materials (Basel) 2021 Apr 6;14(7). Epub 2021 Apr 6.

Department of Pharmacy, Health and Nutritional Sciences, University of Calabria, Arcavacata di Rende, 87036 Cosenza, Italy.

In the last years, neurological diseases have resulted in a global health issue, representing the first cause of disability worldwide. Current therapeutic approaches against neurological disorders include oral, topical, or intravenous administration of drugs and more invasive techniques such as surgery and brain implants. Unfortunately, at present, there are no fully effective treatments against neurodegenerative diseases, because they are not associated with a regeneration of the neural tissue but rather act on slowing the neurodegenerative process.

Factors influencing the sinus membrane thickness in edentulous regions: a cone-beam computed tomography study.

Int J Implant Dent 2021 Mar 2;7(1):16. Epub 2021 Mar 2.

Tokyo Medical and Dental University Dental Hospital, Tokyo Medical and Dental University, Tokyo, Japan.

Background: During implant treatment in the maxillary molar area, maxillary sinus floor augmentation is often performed to ameliorate the reduced alveolar bone height attributable to bone remodeling and pneumatization-induced expansion of the maxillary sinus. However, this augmentation may cause complications such as misplaced implants, artery damage, and maxillary sinus mucosal perforation; infections like maxillary sinusitis; and postsurgical complications such as bone graft leakage and postoperative nasal hemorrhaging. To reduce the complications during maxillary sinus floor augmentation and postoperative infections, we performed retrospective investigations of various systemic and local factors that influence pre-operative sinus mucosal thickness (SMT) by using cone-beam computed tomography (CBCT).

Evaluation of different surgical approaches to remove dental implants from the maxillary sinus.

Sci Rep 2021 Feb 24;11(1):4440. Epub 2021 Feb 24.

North End Medical Centre, London, UK.

Dental implant surgery on atrophied maxilla has many risks; in some patients, simultaneous sinus lifting with implant placement must be performed to increase the chances of successful implantation; this procedure can cause implant migration. Eleven patients were diagnosed with implant migration into the maxillary sinus in four anatomical areas: the sinus floor above the alveolar bone, near the junction of the sinus and nasal floor, near the floor of the orbit, and the most posterior aspect of the sinus. Surgical removal was performed through four different direct non-endoscopic transoral approaches depending on the location of the displaced implant. Read More
