Clinical Studies On Surgical Management Of Ear Affections In Buffalo
 
Description The study entitled “Clinical Studies on Surgical Management of Ear
Affections in Buffalo" was undertaken at the Department of Veterinary
Surgery & Radiology, Nagpur Veterinary College, Nagpur. A total number
of 221 buffaloes were screened in and around Nagpur city during
December 2011 to June 2012. Out of these, 18 clinical cases suffering
from ear affections were included in the study. Total 14 cases were
suffering from otitis (77.77%) out of which, eleven (78.57%) cases were of otitis externa and three (21.43%) were of chronic otitis externa with otitis
media. Two cases of ear pinna abscess (11.11%) and two cases of foreign
body lodgment (11.11%) were also recorded.
Otitis was predominantly observed in Murrah breed (42.85%)
followed by non-descript (35.70%) and Nagpuri (21.45%). The highest
incidence of otitis was observed in the age group of 3 to 6 years (57.10%).
The examination of ear pinna was carried out in cases having ear
affections. In two cases, abscesses of lateral wall of the ear pinna was
recorded. Examination of ear canal in two cases revealed foreign bodies
obstructing the ear canal. The cases of otitis exhibited various symptoms
such as head shaking, intermittent rotation of the head towards the affected
side, purulent discharge through the ear canal and scratching of affected
ear with the hind leg hooves were commonly observed in all cases of otitis
externa.
The microbiological investigations indicated a total of 15 isolates from the
discharge from the ear canal. The predominant bacteria causing otitis were
Staphylococci spp. (n=5, 33.33%), Bacillus spp. (n= 3, 20%), Streptococci spp.
(n= 3, 20%), E. coli (n= 2, 13.33%), and Proteus spp. (n= 1, 6.66%) and mixed
culture of E. coli and Bacillus spp. (n= 1, 6.66%). Overall antibiotic sensitivity test
of bacterial isolates indicated amoxicillin as the most effective (100%) antibiotic
followed by norfloxacin (92.86%), enrofloxacin (85.72%), ciprofloxacin (85.72%),
gentamycin (64.29%), streptomycin (64.29%), erythromycin (57.15%), and
oxytetracycline (50.00%).
The haematological parameters viz. haemoglobin, PCV and TEC did
not differ significantly in cases of otitis externa, whereas neutrophilia with
leucocytosis was observed in cases of otitis
The foreign body lodgment was recorded in two cases at the angle
of the canal which were retrieved manually. The abscesses of the wall ear
pinna recorded in two cases were lanced by usual surgical procedure.
Total fourteen cases of otitis were treated initially with conservative
treatment. Out of these 14 cases, three cases did not respond to conservative treatment and were subjected to surgical treatment by ear
canal lateral wall resection.
All the fourteen cases of otitis were subjected to conservative
treatment which included clipping of the hair around the external ear orifice
cleaning of ear canal with 2% hydrogen peroxide solution and then the ear
pinna and vertical ear canal was painted with povidine iodine solution.
Depending upon the cultural sensitivity test, antibiotics were selected and
administered intramuscularly for ten consecutive days and ear drops were
instilled for ten days. Conservative treatment provided satisfactory results
in 11 cases and three cases of otitis externa did not respond to the
conservative treatment. Surgical intervention was undertaken in these
cases.
The surgery was performed under sedation with Triflupromazine
hydrochloride and local infiltration. All the three cases responded to the
surgical intervention and the symptoms of the otitis were not observed after
fifteen days postoperatively. All three cases recovered uneventfully with the
surgical intervention.
The study revealed that the cases of otitis externa can be managed
conservatively in the initial stages. However, the chronic or cases refractory
to the conservative treatment requires surgical intervention in order to
avoid the recurrence of the condition.
