INTRODUCTION: Most children with otitis media with effusion (OME) recover spontaneously before adolescence. However, some children have refractory OME. This study was undertaken to evaluate eustachian tube function and concurrent upper respiratory tract inflammatory conditions in adolescents with refractory OME. METHODS: A group of 83 adolescent patients with refractory OME was identified. Ages range from 10 to 20 years. A control group of 108 children with OME (ages 4 to 9) serve as the basis for comparison. All underwent both passive and active eustachian tube function testing, dye clearance studies, and a sniffing test. Upper respiratory tract inflammation was assessed by roentgenograms of the paranasal sinuses and mucosalivary function. RESULTS: High-pressure tubal opening was demonstrated in 31% of patients with refractory OME. In contrast, 84% of children with routine OME had normal opening. A marked disturbance of dye clearance was noted in refractory OME cases. Active tubal function during swallowing was disturbed in both adolescent and children's OME groups without any significant difference between them. Paranasal sinusitis was identified in 49% of adolescents with refractory OME. In contrast, 78% of children with OME had abnormality of the sinuses. CONCLUSION: Approximately one half of adolescents with refractory OME have demonstrable organic abnormality of the eustachian tube. These data suggest tubal dysfunction may be more important in refractory OME than upper respiratory tract inflammation.

A new microviscometer for determining the viscosity of middle ear effusion.

A new microviscometer has been developed based on the capillary viscometer method. The device uses a glass sensor tube for aspirating 15-microliter samples. The relative viscosity of the samples was estimated from the negative pressure required for aspiration of the fluid. These pressures ranged widely from 1 centipoise (cp) to 10,000 cp. Measurement of the viscosity of middle ear effusions in 119 samples from 110 otitis media with effusion patients using this device revealed a close relation between their values and their gross appearance (serous less than seromucoid less than mucoid). The microviscometer is useful to determine the relative viscosity of a very small amount of fluid such as middle ear effusion.

Neonatal mature teratoma of the sphenoidal sinus: a case report.

Teratoma in the head and neck region is very rare. We treated a child with a mature congenital teratoma that arose from the right sphenoidal sinus. He is doing well after early surgical treatment with endoscopic endonasal resection of the tumor.
