The lacrimal bones are two small and fragile bones of the facial skeleton; they are roughly the size of the little fingernail and situated at the front part of the medial wall of the orbit. They each have two surfaces and four borders. Several bony landmarks of the lacrimal bones function in the process of lacrimation. Specifically, the ...
For example, fractures of the orbital floor or medial orbital wall of the eye can entrap the medial rectus or inferior rectus muscles. [29] In facial wounds, tear ducts and nerves of the face may be damaged. [3] Fractures of the frontal bone can interfere with the drainage of the frontal sinus and can cause sinusitis. [30]
A skull fracture is a break in one or more of the eight bones that form the cranial portion of the skull, usually occurring as a result of blunt force trauma.If the force of the impact is excessive, the bone may fracture at or near the site of the impact and cause damage to the underlying structures within the skull such as the membranes, blood vessels, and brain.
Palpebral emphysema refers to emphysema of the eyelids alone. It is a rare kind of orbital emphysema which is usually caused by fractures of the lacrimal bone. [6] [3] [36] The lacrimal sac ruptures as a result of the fracture, allowing air from the nasal cavity to enter the tissues of the eyelid.
Osteoarthritis is caused by the breakdown of cartilage at the ends of long bones over years of wear and tear. Many factors can contribute to the development of osteoarthritis, including: Joint injury.
A basilar skull fracture is a break of a bone in the base of the skull. [1] Symptoms may include bruising behind the ears , bruising around the eyes , or blood behind the ear drum . [ 1 ] A cerebrospinal fluid (CSF) leak occurs in about 20% of cases and may result in fluid leaking from the nose or ear . [ 1 ]
Research shows that up to 10 percent of U.S. men may have signs or symptoms of Peyronie’s disease, though only about 1 percent seek treatment. While many men may have some degree of curvature ...
Early treatment by fracture reduction with stenting of the entire lacrimal drainage system should be considered. However, such injuries are often not recognized or are initially neglected as more serious injuries are managed. In such cases, late treatment of persistent epiphora usually requires dacryocystorhinostomy.
