Abstract
A revisit to high riding jugular bulb with a newer classification. Observational study. Patients in the age group between 15 to 60 years, who underwent various Tympanomastoid and otosclerotic surgeries from April 2015 to 2018, have been included in the study. An analysis was made on high riding jugular bulb which encountered and different anatomical variations were noticed. A total of 531 patients underwent various tympanomastoid surgeries and 48 patients underwent otosclerotic surgeries. Out of which 8% of the cases (n = 49) were noticed to have high riding jugular bulb. In those 49 cases, 81% (n = 37) have Grade I, 11% (n = 5) have Grade II, 6% (n = 3) have grade III, 6% of the case (n = 3) have Grade IV and 2% (n = 1) has Grade V high riding Jugular bulb. Among these the prevalence of Grade I jugular bulb is high followed by Grade II. With the observation of our clinical study the authors have made a revisit to high riding jugular bulb and proposed a new clinical grading for high jugular bulb called BPH, that is Basava Prasad’s grading clinical on High jugular bulb (Channa Basava Hubli and K. C. Prasad) as: Grade I high riding jugular bulb up to the level of inferior tympanic annulus. Grade II extending from the level of tympanic annulus up to the inferior margin of the round window niche. Grade III Completely obliterating the round window niche. Grade IV Lies between superior margin of round window niche and stapes. Grade V Abuting the Stapes Arch.
