Publisher: 2015Dissertation note: The dog is one of the ancient pet animals which man is keeping for centuries. There are a number of infectious and non-infectious diseases from which the dogs suffer. Ear as an important part of the body also suffers from many diseases such as otitis externa, otitis media and otitis interna. The inflammatory ailment of external ear canal is called as otitis externa. In small animal practice 10-20% of the admitted dogs are reported with problem have the problem of otitis externa. There are different techniques for the treatment of otitis externa such as medicinal and surgical procedures. Among the surgical procedures the one procedure is total ear canal ablation. Total ear canal ablation is procedure in which both horizontal and vertical ear canals are surgically removed. In case of unresponsive condition of the skin, there is preference of TECA over lateral ear resection and should be done in combination with a lateral bulla osteotomy.
The present study was conducted on 16 clinical cases of Pet Centre, University of Veterinary and Animal Sciences (UVAS), Lahore. The dogs were divided into two groups A and B, each group with 8 dogs. Group A was surgically operated for total ear canal ablation with lateral bulla osteotomy (LBO) and was further divided into two groups (A-I, A-II), in which 4 dogs were surgically treated by TECA-LBO along with surgical placement of a passive drain system (Group A-I) and remaining 4 dogs were treated by TECA-LBO without placing the drain (Group A -II). Group B was surgically operated for total ear canal ablation without lateral bulla osteotomy, it was further divided into two groups (B-I, B-II), in which 4 dogs were surgically treated by TECA along with surgical placement of a passive drain system (Group B-I) and remaining 4 dogs were treated by TECA without placing the drain (Group B -II).

Out of total 16 dogs from all 4 subgroups having 4 dogs in each, wound infection was present in total 1, 2 and 1 dog of group A-I, B-I and B-II respectively, while there was no wound infection in all dogs of group A-II. Out of the total 16 dogs from all 4 subgroups having four dogs in each wound was healed in total 3, 4, 2 and 3 dogs in group in A-I, A-II, B-I and B-II respectively, while there was no healing of wound in total 1, 2 and 1 dog of group A-I, B-I and B-II respectively. The results of white blood cell count for present study showed that out of total 16 dogs from all 4 subgroups having 4 dogs in each, white blood count was different from normal range in total 1, 2 and 1 dogs of group A-I, B-I and B-II respectively indicating the infection while white blood cell count was in normal range of total 3, 4, 2 and 3 dogs in group A-I, A-II, B-I and B-II respectively. The result of present study for the wound complications showed that out of total 16 dogs from all 4 subgroups having 4 dogs in each, there were presence of complications in total 1, 2 and 1 dog of group A-I, B-I and B-II respectively, while there was no wound complication in all dogs of group A-II. It can be concluded from the results of wound infection, wound healing time, white blood cell count and wound complications for the present study, total ear canal ablation with lateral bulla osteotomy is a comparatively better technique then total ear canal ablation alone.

Publisher: 2015Dissertation note: Bone graft was considered as the most commonly transplanted tissue to enhance ability to heal fractures, fracture complications and bone defects. Autologous (or autogenous) bone grafting involves utilizing bone obtained from the same individual receiving the graft. Autogenous bone graft was considered to be the gold standard for replacement of lost tissue. New bone graft substitutes have been devised in recent decades such as synthetic bone graft i.e. poly methyl methacrylate (PMMA), demineralized bone matrix (DBM), bone morphogenetic proteins (BMPs), calcium phosphate (CP), calcium sulfate (CS), hydroxyapatite (HA), highly purified bovine and xenograft , but clinical evidence of their efficacy varies among clinical and experimental studies.
Autograft (along with full cerclage wiring) was a better technique than poly methyla methacrylate (PMMA) for repair of bone defects in animals.
A total of 16 rabbits were divided into two groups i.e. group I and group II, 12-14 weeks of average age having average body weight of 1.5 kg were selected randomly and maintained at Pet Centre, Department of Clinical Medicine and Surgery, UVAS, Lahore. Then, a defect were experimentally created having dimension 4.5 mm wide and 8 mm deep using a lateral surgical approach in left femur in all the animals of each experimental group. Post-operative evaluation was done on the basis of radiological findings, degree of lameness and histopathology findings for the comparison of autograft and synthetic bone graft.

Conclusion
It was concluded from the present study that autograft was superior to poly methyl methacrylate by radiological findings, degree of lameness and histopathological findings. Autografting was the gold standard for fracture healing to be biocompatible, osteogensis, osteinductive and osteoconductive.
