Vit. E and Post-grommet Myringosclerosis.......
Myringosclerosis following myringotomy with
ventilation tube (MVT) placement is common. While
previous animal studies have focused on the effect
of antioxidants in preventing myringosclerosis in
animal models, Uneri, Baglam & Yazici
recently (Int
J Pediatr Otorhinolaryngol.
2005 Dec 17) studied the effect of
Vitamin E in preventing tympanosclerosis in human
subjects and observed that addition of Vitamin E
to the ear following MVT reduced the incidence of
tympanosclerosis by about half.
Abstract: OBJECTIVES: Recent studies
have established the relationship between the
reactive oxygen species and myringosclerosis.
Furthermore several antioxidants have been known
to prevent myringosclerosis. All the previous
studies supporting this hypothesis have been
performed on animals. The aim of our study is to
investigate the possible effect of Vitamin E on
the development of tympanosclerosis after VT
insertion on human subjects. METHODS: 72 children
undergoing myringotomy and VT insertion were
included in the study. Vitamin E was applied to
the right ear and no treatment was applied to the
left ear. Both ears were examined at the end of 9
months with otomicroscopy. Myringosclerosis
formation at the end of the study period was noted
for each ear. RESULTS: Myringosclerosis was found
in 33 of the 144 ears. The overall incidence was
22.9%. While 22 (30.6%) of the 72 left ears showed
myringosclerosis otomicroscopically, in only 11
(15.3%) of the 72 right ears that were treated
with Vitamin E was myringosclerosis observed at
the end of the study period. Of these nine cases
were bilateral. CONCLUSION: Animal studies have
well documented the development of
myringosclerosis after myringotomy and VT
insertion and beneficial effects of different
antioxidants. Our study has shown similar results
in human subjects. Further clinical studies
consisting of a larger patient population are
needed to bring about routine clinical use of
antioxidants in myringotomy and VT insertion.

 Vocal
cord Length Vs Gender & Height...?
A not-too-recent study from Filho et al (Ann
Otol Rhinol Laryngol 2005:390-392.) attempted
relating the length of the membranous vocal cord with
gender and sex and arrived at a mathematical equation to
determine vocal fold length in either of the sexes based
on the body height.
Abstract: To obtain a mathematical equation
that could estimate the length of the intermembranous
part of the vocal fold as a function of body height and
gender, we removed the larynges from 39 cadavers (22 men
and 17 women) after recording the subject’s height, age,
and cause of death. The dimensions of the vocal folds
were determined with a digital pachymeter. The following
equations were obtained: y = 0.18x – 15.8 for men and y
= 0.24x – 28.1 for women, where y is the length of the
intermembranous part of the vocal folds in millimeters
and x is the height of the individual in centimeters. We
conclude that it is possible to estimate the normal
expected length of the intermembranous portion of the
male and female vocal folds on the basis of body height.

Day-case Mastoidectomy, Tympanoplasty.....?
Modify your Anaesthesia for faster recovery, provide
meds for prevention of early post-op nausea and vomiting
and you may be on your way to carrying out major ear
surgeries as day case, as this study from Essex (Qureshi
AA,
Padgham ND,
Jiang D,
J Laryngol Otol.
2006 Jan;120(1):5-9) appears to indicate
 Abstract:
Introduction: At present there is a strong emphasis on
carrying out more elective day-case surgery. This paper
presents a series of major ear cases performed on a
day-case basis. Method: This is a retrospective review
of outcome. Surgery was performed over 10 years at the
Queen Elizabeth Queen Mother Hospital (part of the East
Kent NHS Trust, UK). Results: Over 10 years 253 major
ear cases were performed. The unplanned admission rate
for overnight stay was 2.8 per cent and the rate of
short-period transfers to in-patient wards (for less
than a six-hour stay) was 2 per cent. Conclusions: Our
experience shows that major ear surgery, including
mastoidectomy, is safe on a day-case basis in all age
groups. With the advent of new anaesthetic agents
recovery is faster, and modern anti-emetic cover for
post-operative nausea and vomiting makes nearly all such
major ear surgery feasible as day-case procedures.

CLINICAL PHOTOGRAPH OF THE WEEK |
 A
40-year old male presented with progressive painless
right cheek swelling of 6 months duration.
The swelling was associated with systemic symptoms
of tiredness, easy fatigability and recurrent
fever. There was no associated oral or pharyngeal
thrush. Examination revealed firm swelling over
the right parotid area. CT-Scan showed the feature
displayed on this radiograph. You may want to see
other
views of the CT
for clarity
