Removal of symptomatic craniofacial titanium hardware following craniotomy: Case series and review

Palejwala, Sheri K., Skoch, Jesse, Lemole, G. Michael 06 1900 (has links)
UA Open Access Publishing Fund / Titanium craniofacial hardware has become commonplace for reconstruction and bone flap fixation following craniotomy. Complications of titanium hardware include palpability, visibility, infection, exposure, pain, and hardware malfunction, which can necessitate hardware removal. We describe three patients who underwent craniofacial reconstruction following craniotomies for trauma with post-operative courses complicated by medically intractable facial pain. All three patients subsequently underwent removal of the symptomatic craniofacial titanium hardware and experienced rapid resolution of their painful parasthesias. Symptomatic plates were found in the region of the frontozygomatic suture or MacCarty keyhole, or in close proximity with the supraorbital nerve. Titanium plates, though relatively safe and low profile, can cause local nerve irritation or neuropathy. Surgeons should be cognizant of the potential complications of titanium craniofacial hardware and locations that are at higher risk for becoming symptomatic necessitating a second surgery for removal.

Deformační a napěťová analýza lebečních fixátorů / Stress-strain analysis of cranial fixators

Klištinec, Dávid January 2018 (has links)
Zranenia hlavy si často vyžadujú lekársku starostlivosť, pri ktorej dochádza k stabilizácii alebo náhrade poškodeného tkaniva. Pre tento účel slúži kranioplastika, ktorá prinavracia pacientovi ochranný a kozmetický výsledok. Výber správneho materiálu kraniálneho implantátu je veľmi podstatný. Naviac potrebuje správny druh fixácie, ktorá ho udrží na mieste a predíde sa tak nedovolenému pohybu implantátu počas bežného života pacienta. Táto práca analyzuje deformačné a napäťové stavy dvoch druhov fixačných plátov prichytených na PMMA implantáte a ich mechanickej odozvy na rozličné záťažné podmienky spôsobené rôznymi stavmi kraniálnej hypertenzie a silou pôsobiacou na sústavu z exteriéru.
