The aim of this study was to compare anatomical and audiological results of boomerang-shaped chondroperichondrial graft (BSCPG) with temporal muscle fascia in type 1 tympanoplasties. Sixty-eight patients in BSCPG group and 54 patients in fascia group were evaluated. Otomicroscopic examination was done periodically till 24 months as for graft perforation, lateralization and retraction and mean air conduction threshold and airbone gap values were measured. At long term controls, in BSCPG group, rates of neomembrane, perforation, retraction and lateralization were 91.17 % (n = 62), 8.82 % (n = 6), 4.41 % (n = 3) and 0 % (n = 0), respectively. In fascia group, the corresponding rates were 79.62 % (n = 43), 20.37 % (n = 11), 12.96 % (n = 7) and 3.7 % (n = 2), respectively. In both groups, mean postoperative PTA and ABG values were significantly better while postoperative same values were significantly different between groups (p = 0.044 and 0.032, respectively). Compared to fascia, BSCPG is an ideal grafting technique in the repair of tympanic membrane perforations.

As the face ages, the skin, fat, muscle, and fascia descend, and the underlying bone, cartilage, and teeth may lose mass. Oculofacial aging is a multifactorial process that is influenced by genetic, environmental, and lifestyle factors. This review summarizes the patterns of oculofacial aging that are observed across populations, including variations in periorbital hollowing, eyelid ptosis, and skin elasticity.

Muscles and their tendons present a considerable diversity of morphological variations. The aim of this study was to explore variants of muscles and tendons from compartments of the thigh and to raise awareness about potential problems during ultrasound examination. This comprehensive review of the literature was created on the basis of scientific articles sourced from PubMed.

Preoperative muscle atrophy leads to persistent gait abnormalities in patients undergoing total hip arthroplasty (THA). Efficient motor learning of the gluteus medius is crucial for their recovery. In this study, a single-joint hybrid assistive limb (HAL) was developed to assist hip abduction.

Ectopic calcifications occur in tendons, ligaments, entheses, muscles, and fasciae, and are often associated with pain and inflammation. In clinical settings, these calcifications are commonly treated by physical therapy and/or surgical interventions. However, there is not enough understanding of pharmacological treatments as primary cures, supportive therapy to physical or surgical treatment, or even preventive measures to avoid or diminish the development of ectopic calcifications.

In the past two decades, interest in the fascial system has exponentially increased, particularly manual treatment and stretching exercises. The fascia's fundamental role remains the transmission of tensions, although this function can be impaired due to excessive or reduced stiffness. This second part of the work outlines the basic principles concerning the importance of appropriate and balanced fascial stiffness for correct postural and functional maintenance of the human body.
