Over the nasal bones and lateral cartilages the skin is thin and fairly freely movable. The skin is much thicker, contains more glands, and is firmly adherent over the alar cartilages. The blood supply is mainly in the soft tissues. The dissection should lie in planes of cleavage whereby vessels are avoided and bleeding is minimized. The bony nose consists of paired nasal bones which are thin i...

BACKGROUND The current study evaluates the mortality of 2,354 workers first employed at a Baltimore chromate production plant between 1950 and 1974. METHODS The National Death Index (NDI Plus) was used to determine vital status and cause of death. Cumulative chromium (VI) exposure and nasal and skin irritation were evaluated as risk factors for lung cancer mortality. RESULTS There are 91,18...

Tissue eosinophilia is a characteristic feature of a number of inflammatory diseases including asthma and nasal polyposis. Eosinophil migration into tissues is controlled in part by interactions between eosinophil adhesion receptors and counter-structures on the vascular endothelium. To determine the receptors used by eosinophils to adhere to vascular endothelium in allergic inflammation we hav...

Most patients with acute hepatitis C (HCV) infections are asymptomatic, while 15% present with jaundice. Intranasal drug use can uncommonly transmit HCV via contaminated instruments and nasal epithelial breakdown. Given a 15% prevalence of HCV infection in chronic methamphetamine users, recognition of potential transmission routes is important to target prevention and screening efforts in this ...

BACKGROUND Full-thickness skin grafts (FTSGs) are useful for reconstructing nasal defects. Traditional reported donor sites include the preauricular, postauricular, supraclavicular, clavicular, conchal bowl, melolabial fold, and upper eyelid skin. Selection of the "best" donor site is based on the "best" tissue match and ability to camouflage the donor scar. OBJECTIVE The purpose was to repor...

IMPORTANCE Nasal defects commonly are a result of removal of skin lesions, and reconstruction presents a cosmetic challenge to surgeons. Conventional thought and study results have held that cosmetic outcomes of local flap reconstructions may be superior to those of skin grafts. However, local flap reconstructions require more adjunctive procedures. We propose that in select cases, skin grafts ...

Nasal reconstruction is always challenging for plastic surgeons. Its midfacial localisation and the relationship between convexities and concavities of nasal subunits make impossible to hide any sort of deformity without a proper reconstruction. Nasal tissue defects can be caused by tumor removal, trauma or by any other insult to the nasal pyramid, like cocaine abuse, developing an irreversible...

Fibroepithelial polyp (FEP) is a benign tumor of mesodermal origin, which mostly found on the skin. FEPs in upper respiratory system are reported originating from oropharynx and larynx, rarely nasal cavity. A 57-year-old female presented with polyp-like lesion right septal mucosa adjacent to mucocutaneous junction. The mass was surgically removed, diagnosis FEP made based histopathological revi...

Temperatures of the brain, skin, and nasal mucosa were recorded along with the cortical electroencephalogram (EEG) in chaired, conscious pigtail monkeys at 25 degrees C air temperature. In undisturbed animals, skin temperatures ranged from 34 to 37 degrees C. When the animal was alerted by visual or auditory stimuli, temperatures on the extremities, tail, nose, ears, and nasal mucosa dropped ra...
