We recommend that every patient with a midline nasal dermoid be evaluated preoperatively by fine-cut CT scan, in the axial and coronal planes, using both bone and soft-tissue algorithms. Because of CT limitations for assessing soft tissue at the cranial base, a complementary thin-section, high-resolution, multiplanar MRI scan should be considered. Transnasal endoscopic excision of midline nasal dermoid should be used if the dermoid is located within the nasal cavity, and there is minimal or no cutaneous involvement. This approach can be combined with a short vertical midline lenticular excision of a cutaneous punctum. Vertical cutaneous excision should be limited; the best location is the nasal tip. Vertical nasal scars over the bony pyramid invariably widen no matter what intradermal suture is used. Endoscopic removal should be considered even if preoperative radiologic studies show extension to the anterior cranial fossa. Endoscopic excision could also be used to resect a dermoid extending between the dural leaves of anterior fossa. However, a combined intra-extracranial approach is necessary if the dermoid is in the falx cerebri. We agree with other authors that frozen sectioning the superior margin of the specimen should be done to ensure that there is no intracranial extension. Valsalva maneuver during endoscopic visualization of the cranial base is a valuable means of ruling out a cerebral spinal fluid leak.

Calcium phosphate cements (CPCs) augment the healing of bone following craniofacial and maxillofacial surgery. Their ability to function as bone substitutes has accelerated the healing processes from bone fractures or defects. Although CPCs all possess the same general function, small chemical composition differences in these compounds have a profound impact on their in vivo character. The main purpose of this article is to report the differences of several major CPCs. When available, specific clinical trials are referenced. The goal is to expand the knowledge base on CPCs to better inform the clinician and researcher.

This article is a review of five patients who underwent reconstruction of nasal and paranasal facial defects with prelaminated forearm free flaps. The defects resulted from thermal injury, gunshot wound, excision of tumor, and arteriovenous malformation (n = 2). The forearm flaps were based on the radial artery (n = 4) and ulnar artery (n = 1) and were prelaminated with grafts of skin and cartilage. All flaps were successfully transferred to the face, but revisions were needed to separate the subunits and improve appearance. A prelaminated free flap should be considered for a patient requiring reconstruction of a complex central facial defect.
