Autologous fat grafting as a minimally invasive technique to avoid cochlear implant extrusion.

ObjectivesInfection of the skin-muscle flap is one of the most severe risks of cochlear implantation. The aim of this paper is to describe a novel and minimally invasive procedure to avoid cochlear implant (CI) extrusion.Methods: A 79-year-old woman with severe comorbidities developed a pressure injury of the skin-muscle flap overlying the CI receiver/stimulator (R/S) nine years after surgery. Skin thinning and failure of conventional pressure injury management led the patient to a high risk of CI extrusion. Therefore, she underwent a single procedure of autologous fat grafting under local anesthesia to increase scalp thickness and vascularization over the CI R/S.Results: Within one month, complete healing of the pressure injury was observed, and the patient was able to safely use her CI. No further signs of infection and skin deterioration were detected at the 15-months follow-up.Discussion: Fat grafting has been proven to promote neoangiogenesis and tissue regeneration. To the best of our knowledge, this is the first report of fat grafting utilized in the skin-muscle flap area to avoid incipient CI R/S extrusion.Conclusion: The described case demonstrates the efficacy of this salvage procedure to avoid major surgery and the additional costs related to CI reimplantation.

Primary nasal tip surgery: a conservative approach.

BACKGROUND: Rhinoplasty and rhinoseptoplasty are very important and complex surgical procedures because the nose plays a pivotal aesthetic role in the face and an important functional role in breathing. Mild bulbous, plunging, undefined tips are very common, and tip refining and repositioning often are required surgical procedures. METHODS: For 97 selected patients, the authors performed their personal technique consisting of a transcartilaginous approach, incomplete vertical interruption, and retrograde undermining of the lower lateral cartilages to improve tip projection and definition. The five aspects analyzed were nasal tip symmetry, nostril symmetry, tip projection, tip definition, and appearance of the nasal tip only. Each parameter was assessed using pre- and postoperative quantification according to a visual analog scale. Postoperative evaluation was performed during a mean follow-up period of 1 year. RESULTS: The results at 1 year showed high rates of improvement in tip definition (mean, 7.9±2.4) and nasal tip only evaluation (mean, 6.5±3.1). The patients reported an improvement in nasal tip symmetry (mean, 4.2±3.2), nostril symmetry (mean, 4.5±4.1), and tip projection (mean, 5.8±2.9). CONCLUSIONS: This simple, safe, and effective technique is proposed for mild bulbous, plunging, undefined, and hypoprojected tips.
