Wound closure techniques other than sutures Part 2

STRENGTH AND SECURITY

In less than three minutes, DERMABOND adhesive provides the strength of healed tissue at 7 days. A strong, flexible 3-dimensional bond makes it suitable for use in closing easily approximated incisions of many types (example—deep, short, long). Continue reading →

Wound closure techniques other than sutures Part 1

Wound closure techniques have evolved from the earliest development of suturing materials to comprise resources that include synthetic sutures, absorbables, staples, tapes, and adhesive compounds. The engineering of sutures in synthetic material along with standardization of traditional materials (eg, catgut, silk) has made for superior aesthetic results. Similarly, the creation of natural glues, surgical staples, and tapes to substitute for sutures has supplemented the armamentarium of wound closure techniques. Aesthetic closure is based on knowledge of healing mechanisms and skin anatomy, as well as an appreciation of suture material and closure technique. Choosing the proper materials and wound closure technique ensures optimal healing. Continue reading →

Le Fort fractures Part 2

Diagnosis

Diagnosis is made based on physical exam findings with confirmation by axial CT. The patient is taken for radiography of the head and neck then after obvious fracture signs the patient is taken to CT scan for more specific anatomic information. To qualify for LeFort Fractures the pterygoid plates must be involved. These are seen posterior to the maxillary sinuses on axial CT and inferior to the orbital rim on coronal slices. Also, the palate is usually mobile on physical exam. Continue reading →

Le Fort fractures Part 1

Le Fort fractures (also spelled as LeFort fractures) are types of facial fractures involving the maxillary bone and surrounding structures in a usually bilateral and either horizontal, pyramidal or transverse way. LeFort fractures are classic in facial trauma. The Le Fort fracture was named after French surgeon René Le Fort (1869–1951), who described them in the early 20th century. Continue reading →

Mental nerve

Mental nerve is a general somatic afferent (sensory) nerve which provides sensation to the anterior aspects of the chin and lower lip as well as the buccal gingivae of the mandibular anterior teeth and the premolars. It is a branch of the posterior trunk of the inferior alveolar nerve, which is itself a branch of the mandibular division of the trigeminal nerve (CN V). The nerve emerges at the mental foramen in the mandibula, and divides beneath the Depressor anguli oris muscle into three branches: Continue reading →
