OBJECTIVE To evaluate a surgical technique used to straighten and support the crooked middle third of the nose. DESIGN Retrospective review of 41 patients with a markedly crooked nose who underwent correction using extended spreader grafts made from high-density porous polyethylene. Follow-up ranged from 6 months to 2 years. RESULTS Every patient had substantial improvement in the straighte...

A 9-year-old boy presented to our department 8 days after attempting to insert a non-piercing magnetic ear stud on either side of his nose. He had been unable to remove them, and both magnetic parts of the ear studs were still present in his nose. Examination of the nose was difficult, as he was unco-operative and his nose was filled with mucus and crusts. X-rays of the nose revealed the two ea...

In this paper, a new practical implementation of a person verification system using features of longitudinal section and transection and other facial, rotation compensated 3D face image, is proposed. The approach works by finding the nose tip that has a protrusion shape on the face. In feature recognition of 3D face image, one has to take into consideration the orientated frontal posture to nor...

E-nose (Electronic nose), which is an array of chemical sensors, is widely used in food industry and pollution control. Nowadays e-nose technology has become powerful tool to evaluate the aroma compounds during the quality control process. This work is intended to detect biological water contaminants like coliform group of bacteria in drinking water. However, a number of limitations are associa...

clearly. I inserted a forceps and removed the foreign body ; it was a butterfly. A few drops of blood followed, but it was soon stopped. 2. A Hindu male child, aged 12 months, was brought to me with bleeding of the nose. The father of the child said that the boy had been putting his finger in the nose since last night, owing to which there had been bleeding. I examined the nose, but could not s...

In this paper, we present a pseudo optimization method for electronic nose (e-nose) data using region selection with feature feedback based on regularized linear discriminant analysis (R-LDA) to enhance the performance and cost functions of an e-nose system. To implement cost- and performance-effective e-nose systems, the number of channels, sampling time and sensing time of the e-nose must be ...

Electronic-detection technologies and instruments increasingly are being utilized in the biomedical field to perform a wide variety of clinical operations and laboratory analyses to facilitate the delivery of health care to patients. The introduction of improved electronic instruments for diagnosing diseases and for administering treatments has required new training of laboratory technicians in...

Cutaneous metastatic carcinoma of the nose is a rare presentation associated with lung cancer. We report here 3 cases of cutaneous metastatic carcinoma of the nose that originated from lung cancer. Two men, age 61 and 76 years, with lung cancers were referred for evaluation of a tumour on the tip of the nose. The third patient, a 57-year-old man, had developed a rosacea-like tumour on the tip o...

A thorough understanding of nasal anatomy is essential to successful nasal reconstruction. Addressing deficiencies of the external soft-tissue envelope, nasal framework, and internal mucosal lining is an important part of achieving an optimal aesthetic and functional outcome. The nose is a highly contoured pyramidal structure situated centrally on the face. It is composed of skin, mucosa, bone,...
