Craniofacial surgeons perform operations that involve exposure of the dura. Typical procedures include cranial vault remodeling (CVR), fronto-orbital advancement (FOA), Le Fort III, monobloc, bipartition advancement, or distraction. Cerebrospinal fluid (CSF) fistulas remain one of the most common complications encountered, occurring in up to 30% of patients. Cerebrospinal fluid fistulas can be encountered intraoperatively, acutely, or in the late postoperative period. Traditional management has been well described in the neurosurgical literature...

Lymphatic malformations (LMs) are rare, nonmalignant masses, frequently involving the head and neck, potentially causing impairment to the surrounding anatomical structures. Major LMs frequently cause facial disfigurement with obvious consequences on self-esteem and social functioning. The attempt to restore symmetry is thus one of the main goals of treatment. In this study, the authors present a not-invasive method to objectively quantify the symmetry of the labial area before and after surgical treatment of a LM, affecting a 16-year-old woman...

The nasal valve area is the functional area that allows airflow regulation. It could be divided in an internal area and an external one, basing on the anatomical landmarks. Many conditions can damage these areas with a consequently nasal obstruction, more often in particular extended rhinoplasty and sequels of facial trauma. To restore this area many techniques were advocated during the last decades.In this article the authors investigate on valve areas deficiency in sequel of rhinoplasty proposing a structural approach through alar batten grafts to correct internal-external nasal valves collapse...

Among various biomaterials used as scaffolds in tissue engineering, silk fibroin is a highly attractive material. A scaffold should be biocompatible and nontoxic, with optimal physical features and mechanical properties. For this reason, tissue-engineering approaches in regenerative medicine have focused on investigating the biocompatibility of possible biomaterials by analyzing cell-scaffold interaction properties. The aim of the present study was to examine the biocompatibility of silk fibroin as a film (two-dimensional [2D]) and a scaffold (three-dimensional [3D]) after being cellularized with human dental pulp stem cells (hDPSCs)...

Intracranial hemangiopericytoma (HPC) is a rare tumor and accounts for 0.4% of all primary central nervous system tumors. However, it has aggressive behavior in growth and infiltration. The importance of diagnosis and treatment between HPC and meningioma cannot be overemphasized. It is rare that HPC arises from the site of benign meningioma resection. And it would be benefitted to take HPC into account when coming across a patient with meningioma "recurrence."

Yasuhiro Takahashi, Hirohiko Kakizaki
A bifurcated periosteal flap is useful for simultaneous reconstruction of the upper and lower lateral canthal tendons. The original technique harvested the flap horizontally from the frontal process of the zygoma, which mostly resulted in an insufficient flap length because of the narrowness of the zygoma. Here, the authors report the use of a modified bifurcated periosteal flap, raised from the superolateral orbital rim. The lower flap was positioned to slant inferiorly to create a downward slope of the lower eyelid for smooth lacrimal drainage by gravity...

Oral cancer, especially that originates in the maxillary tuberosity, buccal mucosa, and maxillary alveolus, is apt to invade the pterygopalatine fossa, where an intraoral approach is nearly impossible. There are 2 main types of extraoral approach to the pterygopalatine fossa; the anterior approach and the lateral approach. Although the lateral approach has an advantage compared with the anterior approach in terms of cosmetics, after the operation numbness of the lower lip occurs due to the sacrifice of the mental nerve...
