In our study, graft uptake rate was 80% in group I and 95% in group II. Though the graft uptake was more in group II but the difference in both the groups was statistically insignificant. In our study, ear discharge occurred only in 4 cases in group I while in group II, only 1 case on follow up was reported to have ear discharge. But as P value was less than 0.05, so difference was statistically insignificant. In our study, in group I, benefit in dB in pure tone threshold pre-operatively and 4 months after surgery was 9.41 and in group II it was 12.05. Though it was slightly more in latter but difference was statistically insignificant.

In study by Krishnan et al. (2002) post-operative hearing gain was 75% in both groups. Similarly, Balyan et al. (1997) in a study conducted on 48 patients with CSOM, treated by means of tympanoplasty with and without mastoidectomy found no significant difference in graft failure rates or hearing results. They also concurred that the addition of mastoidectomy had increased effort and risk to the surgery. Grew et al. [18] found similar success rate for both the groups.
Myers served from 1968 to 1972 as an Assistant Professor of Clinical Otolaryngology at the University of Pennsylvania School of Medicine in Philadelphia, then became Professor, Chairman, and the first academic faculty member of the Department of Otolaryngology at the University of Pittsburgh in 1972. While serving in that leadership position he increased the size and quality of the school's department of otolaryngology,[3] so that it is widely considered one of the leading programs in the world.[2] In 2006 Dr. Myers was named Distinguished Professor and Emeritus Chair.[5] During his 33-year tenure as chair, he introduced the department to modern head and neck surgery and cultivated a leadingacademic department. He estimates that he has performed more than 9,000 operations and mentored more than 150 residents and fellows. Twenty-five of his former trainees are now chairs at academic institutions.[4] From 1972 to the present he served first as Professor of Clinical Oncology in the Department of Oral Pathology of the University of Pittsburgh School of Dental Medicine, and then as Professor in the Department of Oral and Maxillofacial Surgery at that school.
The Auditory Neuroscience division has a long and successful history of NIH funding, including a Program Project Grant now in its 23rd year. Our NIH support places us 10th nationally for departments of otolaryngology. The department's research budget for the fiscal year 2010 exceeded $5.5 million and involved the following major areas:
There is a growing concern with inappropriate, excessive perioperative blood transfusions. Understanding the influence of low preoperative hemoglobin (Hgb) on perioperative blood transfusion (PBT) in head and ...

The study comprised 20 children selected to undergo DLM for middle-ear ventilation as a mode of treatment for recurrent acute serous otitis media; these children suffered from persistent middle-ear effusion and had experienced failure of medical treatment for at least 8 weeks. Postoperative weekly visits to evaluate the myringotomy opening (MO) were carried out until healing was recorded. The Eustachian tube and hearing ability were evaluated preoperatively and postoperatively 4 weeks after healing of the tympanic membrane. Cases were deemed to be failed when the MO closed early within the second week postoperatively without improvement in hearing, or the myringotomy persisted until the end of the third month postoperatively. Outcome measures were the state of the MO and of the ear drum, the patency time of the myringotomy, improvement in hearing and Eustachian tube function and incidence of operative and postoperative complications.
The mean operative time was 5 min. No operative complications occurred. Procedural success was achieved in 16/20 ears (80%). Two ears showed postoperative persistent perforations, and two recorded early closure of the MO. The mean improvement in the air/bone gap was 12 dB for the successful cases. Twelve ears with healed MOs showed type A curve (75%). Four ears showed type C curve (25%) and needed further management.
Intra-operative measurements showed that the mean distance ( standard deviation) between the horizontal segment of the facial nerve and stapes crura in 10 cases of otosclerosis was 0.74 mm ( 0.21 mm), whereas in 10 cases of non-otosclerosis the same distance was 0.20 mm ( 0.00). There was no gap (0 mm) between the stapes crura and inferior border of the oval window niche in otosclerotic ears, whereas in non-otosclerotic ears the same distance was 0.13 mm ( 0.05 mm). The differences were statistically significant (p 2ff7e9595c
