The zygomaticus major (ZM) is important for the human smile. There are conflicting data about whether zygomatic or buccal branches of facial nerve responsible its motor innervation. literature provides no precise distinction transition zone between these two branch systems. In this study, a definition to distinguish at level body zygoma proposed. light definition, we conducted an anatomical study determine how source innervation ZM was distributed. A total 96 fresh-frozen cadaveric halves...
The facial nerve is responsible for any expression channeling human emotions. Facial paralysis causes asymmetry, lagophthalmus, oral incontinence, and social limitations. dynamics may be re‐established with cross‐face‐nerve‐grafts (CFNG). Our aim was to reappraise the zygomaticobuccal branch system relevant reanimation surgery respect anastomoses crossings. Dissection performed on 106 halves of 53 fresh frozen cadavers. Study endpoints were quantity relative thickness branches, correlation...
We developed a time-efficient semi-automated axon quantification method using freeware in human cranial nerve sections stained with paraphenylenediamine (PPD). It was used to analyze total of 1238 facial and masseteric biopsies. The technique validated by comparing manual 129 (10.4%) randomly selected software-based demonstrated sensitivity 94% specificity 87%. Semi-automatic counting significantly faster (p < 0.001) than counting. took 1 hour 47 minutes for all biopsies (averaging 50 sec...
Radical nephroureterectomy (NUE) is the gold standard treatment for high-risk urothelial cancer of upper urinary tract (UTUC). Besides sarcopenia and frailty, fat distribution moving increasingly into focus. Components body composition were assessed in patients undergoing NUE due to UTUC. The study cohort included 142 patients. By using CT-based measurements, skeletal muscle index (SMI), subcutaneous adipose tissue (SATI), visceral (VATI) measured at height third lumbar vertebra. Overall...
Objective To develop a prognostically relevant scoring system for stage pT1 non‐muscle‐invasive bladder cancer (NMIBC) incorporating tumour budding, growth pattern and invasion because the World Health Organisation grading shows limited prognostic value in such patients. Patients Methods The tissue specimens clinical data of 113 patients with NMIBC who underwent transurethral resection were retrospectively investigated. Tumour patterns evaluated categorised into two grade groups (GGs). GGs...
Facial palsy (FP) is a debilitating nerve pathology. Cross Face Nerve Grafting (CFNG) describes surgical technique that uses grafts to reanimate the paralyzed face. The sural has been shown be reliable graft with little donor side morbidity. Therefore, we aimed investigate microanatomy of nerve. Biopsies were obtained from 15 FP patients who underwent CFNG using grafts. Histological cross-sections fixated, stained PPD, and digitized. Histomorphometry validated software-based axon...
Background The marginal mandibular branch (MMB) of the facial nerve provides lower lip symmetry apparent during human smile or crying and is mandatory for vocal phonation. In treating palsy patients, so far, little attention directed at MMB in reanimation surgery. However, isolated paralysis may occur congenital, Bell's iatrogenic surgery, prone to its anatomical course. A variety therapies address with either weakening functional side reconstruction paralyzed side. To further clarify...

Facial palsy (FP) is a functional disorder of the facial nerve involving paralysis mimic muscles. According to principle “time muscle,” early surgical treatment tremendously important for preserving musculature if there are no signs function recovery. In 49-year-old female patient, even 19 months after onset FP, successful neurotization was still possible by V-to-VII transfer and cross-face grafting. Our patient suffered from complete FP vestibular schwannoma surgery. With continuous...
Background: A commonly seen issue in facial palsy patients is brow ptosis caused by paralysis of the frontalis muscle powered frontal branch nerve. Predominantly, static methods are used for correction. Functional restoration concepts include transfer deep temporal trigeminal nerve and cross-facial grafts. Both techniques can neurotize original mimic muscles early cases or power transplants late cases. Because axonal capacity particularly important graft procedures, authors investigated...
