Background: Radiochromic film is used for radiation dose measurement, XR-RV3 is used in fluoroscopy and EBT2 film in radiation therapy. The aim was to determine if the dosimetric properties of these two films are comparable in megavolt photon beams. Materials and Methods: Comparison measurements included: calibration curves, heterogeneous phantom dose profiles, and nasopharynx dose distributio...
Lodgment of foreign body in the nose/nasopharynx in a sane adult person is unusual. Here, we present the case of a patient who came with an unusual foreign body (fish) lodged in the nose & nasopharynx. It was removed successfully in the outpatient department transorally with aid of nasal endoscopy.
Acute otitis media occurs mostly after upper respiratory tract infection; the causative bacteria are those colonized in the nasopharynx. We studied 709 episodes of upper respiratory tract infection and found that children with no bacteria in the nasopharynx were at low risk for acute otitis media, whereas children with 3 pathogenic bacteria were at the greatest risk.
In stumptail monkeys from birth to adulthood, and in very young human infants, the epiglottis serves to guide the larynx upwardly behind the soft palate so it can lock into the nasopharynx and remain there during respiration. After early infancy in man the attainment of a larynx-nasopharynx connection is uniquely lost, causing the epiglottis to have no essential function.
Mucormycosis is a very commonly encountered disease in the sinonasal region patients with diabetes and immunocompromised status specially northern part of Indian continent. Due to its fulminant nature involvement rhino-orbital-cerebral region, prognosis poor even after extensive debridement amphotericin-B therapy. We present case diagnosis sarcoidosis being treated systemic steroids who develop...
BACKGROUND To investigate patterns of failure and survival rates of elective irradiation of upper neck in N0 nasopharyngeal carcinoma patients. METHODS From February 1996 to November 2002, 97 patients without cervical lymph node involvement were admitted for radiotherapy alone. Before treatment, each patient underwent enhanced CT of nasopharynx and neck. All patients received radiotherapy to ...
