Pathways for the rehabilitation of resection defects in the maxilla.

Br Dent J 2022 Jun 10;232(11):783-789. Epub 2022 Jun 10.

Consultant in Restorative Dentistry, Leeds Dental Institute, The Worsley Building, Clarendon Way, LS2 9LU, UK.

Oral rehabilitation of head and neck cancer patients is an integral component of the care pathway. Maxillectomy procedures can cause significant defects, such as oronasal fistulas, loss of support for the cheek and lip, aesthetic defects in the middle third of the face and functional impairments. Orofacial rehabilitation plays a fundamental role in restoring aesthetics and functional capabilities, such as speech, mastication and deglutition. Read More

The timecourse of multisensory speech processing in unilaterally stimulated cochlear implant users revealed by ERPs.

Neuroimage Clin 2022 4;34:102982. Epub 2022 Mar 4.

University of Cologne, Faculty of Medicine and University Hospital Cologne, Department of Otorhinolaryngology, Head and Neck Surgery, Audiology and Pediatric Audiology, Cochlear Implant Center, Germany.

A cochlear implant (CI) is an auditory prosthesis which can partially restore the auditory function in patients with severe to profound hearing loss. However, this bionic device provides only limited auditory information, and CI patients may compensate for this limitation by means of a stronger interaction between the auditory and visual system. To better understand the electrophysiological correlates of audiovisual speech perception, the present study used electroencephalography (EEG) and a redundant target paradigm. Read More

Choosing the Ideal Implant-Supported Prosthesis for an Edentulous Maxilla: Three Key Prosthetic Parameters.

Compend Contin Educ Dent 2022 Mar;43(3):148-153; quiz 154

Professor, Department of Periodontology, University of Alabama at Birmingham School of Dentistry, Birmingham, Alabama.

Assessment of patient- and prosthetic-specific factors in identifying the ideal implant-supported prosthesis helps enable the delivery of a dental restoration that can meet the esthetic, functional, physiologic, psychologic, financial, and time goals of the patient. For practitioners, determining the relative risks and benefits of removable and fixed implant-supported prostheses for restoration of an edentulous maxilla can be challenging. Proper treatment selection requires thorough examination, diagnosis, and a systematic approach to treatment planning. Read More

Surgical Lip Remodeling Following Permanent Filler Injection: A Scoping Review.

J Craniofac Surg 2022 Mar-Apr 01;33(2):557-561

Department of Neurosciences, Reproductive and Odontostomatological Sciences, Maxillofacial Surgery Unit, University of Naples "Federico II" Naples, Italy.

Abstract: Over the years, several techniques have been introduced to obtain permanent lip enhancement, such as the use of silicone lip implants or the off-label use of permanent fillers. Although some reports indicate that permanent lip filler is safe, many others describe early- and late-onset complications. The main issue with permanent lip fillers is the lack of a standard technique to correct undesirable results. Read More
