Thoracodorsal artery perforator free flap with vascularized thoracodorsal nerve for head and neck reconstruction following radical parotidectomy with facial nerve sacrifice: A step-by-step surgical technique video.

Head Neck 2021 Apr 5. Epub 2021 Apr 5.

Department of Plastic Surgery, Gustave Roussy Institute, University Paris Saclay, Villejuif, France.

Oncological surgery of the parotid region sometimes requires the sacrifice of the facial nerve (parotid cancers, extensive skin cancers of the face, soft tissue sarcomas). The sacrificed portion of nerve can be reconstructed by a vascularized nerve graft, especially if the patient must undergo radiotherapy after surgery. In those cases, the facial nerve sacrifice is associated to an important loss of substance from the parotid region (skin, masseter, parotid, and sometimes jaw). Read More

Transcriptome analysis of molecular mechanisms underlying facial nerve injury repair in rats.

Neural Regen Res 2021 Nov;16(11):2316-2323

Department of Otolaryngology, Affiliated Hospital of Nantong University, Nantong, Jiangsu Province, China.

Although the transcriptional alterations inside the facial nucleus after facial nerve injury have been well studied, the gene expression changes in the facial nerve trunk after injury are still unknown. In this study, we established an adult rat model of facial nerve crush injury by compressing the right lateral extracranial nerve trunk. Transcriptome sequencing, differential gene expression analysis, and cluster analysis of the injured facial nerve trunk were performed, and 39 intersecting genes with significant variance in expression were identified.

Signal processing & audio processors.

Acta Otolaryngol 2021 Mar;141(sup1):106-134

MED-EL Elektromedizinische Geraete Gesellschaft m.b.H., Innsbruck, Austria.

Signal processing algorithms are the hidden components in the audio processor that converts the received acoustic signal into electrical impulses while maintaining as much relevant information as possible. Signal processing algorithms should be smart enough to mimic the functionality of external, middle and the inner-ear to provide the cochlear implant (CI) user with a hearing experience as natural as possible. Modern sound processing strategies are based on the continuous interleaved sampling (CIS) strategy proposed by B. Read More
