Comparison of Tympanoplasty Results in Dry and Wet Ears

Introduction: Tympanoplasty is the standard and well established procedure for closure of tympanic membrane perforations .This paper compares the results of tympanoplasty in terms of hearing improvement and graft incorporation in patients with chronic perforation of the tympanic membrane between two groups with and without active drainage at the time of surgery.  Materials and Methods: Sixty re...

Wet and Dry Etching Theory

Are Dry Mergers Dry, Moist, or Wet?

We present a spectral analysis of a sample of red-sequence galaxies identified by van Dokkum (2005) as dry merger remnants and ongoing dry mergers. Kinematics, stellar population absorption features, and ionisation from emission lines, are derived. We find that approximately half of the sample showing strong tidal features have younger stellar populations than a control sample at a given veloci...

Aggregation Kinetics in “ Dry ” and “ Wet ” Environments

We investigate the kinetics of constant-kernel aggregation which is augmented by either: (a) evaporation of monomers from finite-mass clusters , or (b) continuous cluster growth – i. e., condensation. The rate equations for these two processes are analyzed using both exact and asymptotic methods. In aggregation-evaporation, if the evaporation is mass conserving, i. e., the monomers which evapor...

Tympanoplasty Outcomes in Dry and Wet Ears

Introduction: Chronic suppurative otitis media is a major public health problem in children and adults. Tympanoplasty is a surgical procedure which aims to prevent recurrent otorrhea and restore hearing ability. Objective: To compare the graft uptake and the hearing outcome of tympanoplasty in non cholesteatomatous chronic otitis media between wet and totally dry ears. Methods: A total of 108 w...
