BACKGROUND Ventilation tube insertion is a common treatment for children with persistent otitis media with effusion. Parents are concerned about the morbidity of this procedure and the influence of ventilation tubes on daily activities. Permissibility of swimming is a question that is most often asked. The aim of this study was to investigate the possibility of water penetration through ventila...

Whole-plant corn has been previously investigated as a biomass feedstock. Current approaches are analogous to harvesting whole-plant for livestock feed or biogas production. They include utilizing self-propelled forage harvester harvest the plant bulk material and storing it anaerobically. This process leads grain damage, reducing marketability of after fractionation. work that included anaerob...

BACKGROUND AND OBJECTIVES The aim of this study was to evaluate surgical interventions and hearing rehabilitation in patients with chronic middle ear disease of only hearing ears. SUBJECTS AND METHODS Thirty-one patients with chronic middle ear disease of only hearing ears were enrolled in this retrospective study. Patients were classified into three groups according to the hearing level: gro...

The present investigation for studying correlations and path analysis estimates grain yield contributing characters in maize was carried out at Maize Research Centre Seed Farm, Devihosur eleven characters. Days to 50 per cent tasseling significantly positively correlated with days silking negatively plant height, ear cob length, shelling percentage, hundred weight yield. significant percentage ...

Traditionally, otologists have aimed to produce a clean, dry, safe ear with the best possible hearing result. More recently, "less invasively" has been added to this list of goals. The development of small-diameter, high-quality rigid endoscopes and high-definition video systems has made totally endoscopic, transcanal surgery a reality in adult otology and a possibility in pediatric otology. Th...

We assessed ultrasonic transmission in a dry skull; in a dry skull with water, simulating the living condition; in a cadaver head; and in six human subjects, one of whom exhibited no measurable hearing. By using these preparations, we concluded that fluid conduction is essential in the propagation of sound across the head, whereas the bone pathway is far less effective in that regard. Thus, the...

BACKGROUND Postirradiation otitis media with effusion (OME) is the most common radiotherapy-associated otologic complication associated with nasopharyngeal carcinoma (NPC). This study's aim was to evaluate the efficacy of laser myringotomy followed by intratympanic steroid injection (LMIS) for treating OME in postirradiated NPC patients. METHODS From August 2002 to January 2006, 27 newly diag...

Ear is the most pressure sensitive organ of the body and is susceptible for rupture with altered pressure. Tympanic membrane (TM) perforation reduces the total ratio of surface area, allowing the sound waves to directly pass through the middle ear. However, implications of the tympanic membrane perforation on sound transmission in the middle ear is not well characterised. The study was undertak...
