METHODS: A 56-year-old female presented with a 3-month history of blood-stained nasal discharge. She had been treated with radiotherapy for nasopharyngeal carcinoma 25 years earlier. Flexible nasal endoscopy demonstrated an exposed bone with an edematous posterior nasopharyngeal mass. Computed tomography showed a pre-vertebral mass with destruction of C1 and C2. She underwent occipito-cervical fusion followed by a combined transnasal and transoral endoscopic debridement of non-viable bone in the same perioperative setting. Healing of the raw mucosa was by secondary intention and reconstruction was not performed.
RESULTS: Histopathological examination reported ulcerated inflamed granulation tissue with no evidence of malignancy. During follow-up, she remained neurologically intact with no recurrence.
CONCLUSION: Using both nasal and oral spaces allows placement of the endoscope in the nasal cavity and surgical instruments in the oral cavity without splitting the palate. Hence, the endoscopic transnasal and transoral approach has vast potential to be effective in carefully selected cases of cervical ORN.
METHODS: Selected T2DM participants with peri-implantitis were distributed into 3 groups: Group-1: received a single session of adjunctive (aPDT); Group-2: received a single session of adjunctive (aAGT) (metronidazole 400 mg and amoxicillin 500 mg); and Group-3: received MD alone. Clinical (probing depth [PD], bleeding on probing [BOP], and plaque scores [PS]) and radiographic (crestal bone loss [CBL]) peri-implant variables were recorded. Levels of interleukin (IL)-6 and tumor necrosis factor-alpha (TNF-α) were assessed after the collection of peri-implant sulcular fluid (PISF). All the evaluations were carried out at baseline, 3- and 6-months. The significance level was set to p < 0.05.
RESULTS: At 3-and 6-months of follow-up, all the three groups showed significant alleviation in PS (p < 0.05), BOP (p < 0.05), and PD (p < 0.05) when compared with the baseline. At baseline, no significant variation was observed in all clinical and radiographic peri-implant parameters among all three research groups. At 3-months follow-up, a considerable alleviation of in PS, BOP, PD, and CBL was noticeable in group-1 patients when compared with the baseline. At 6-months follow-up, a comparable difference was observed in BOP, PD, and CBL between group-1 and group-2. At baseline, no significant variation was observed in the PISF levels of IL-6 and TNF-α among all three research groups. At 3- and 6-months follow-up, a considerable alleviation of TNF-α and IL-6 levels was observed in group-1 and group-2 patients, respectively, when compared with the baseline.
CONCLUSION: The application of aPDT demonstrated improved clinical, radiographic, and immunological peri-implant parameters for the treatment of peri-implantitis among T2DM patients.
Material and Methods: This is a prospective case series conducted on patients who were diagnosed with type V osteochondral lesions of talus. All the cases were treated with arthroscopic debridement, microfracture, and PRGF injections. The patients were evaluated for the healing of subchondral cysts and progression of osteoarthritis with radiography (plain radiographs and computerised tomography Scan). Also, the patients' outcome was evaluated with Quadruple Visual Analogue Scale, Ankle Range of Motion, Foot and Ankle Disability Index, Foot and Ankle Outcome Instrument and a Satisfaction Questionnaire.
Results: Five male patients underwent arthroscopic debridement, microfracture and PRGF injection for type V osteochondral lesion of talus. The mean age of patients was 27.4 years (19-47 years). All the patients gave history of minor twisting injury. Subchondral cyst healing was achieved in all patients by six months post-surgery. However, four out of five patients had developed early osteoarthritic changes of the ankle by their last follow-up [mean follow-up 29 months (ranged 15-36 months)]. Despite arthritic changes, all the patients reported 'Good' to 'Excellent' results on satisfaction questionnaire and Foot and Ankle Disability Index and could perform their day to day activities including sports.
Conclusion: Arthroscopic debridement, microfracture, and PRGF causes healing of the subchondral cyst but does not cause cessation of progression to osteoarthritis of ankle in type V osteochondral defects of talus. However, despite progress to osteoarthritis, patient satisfaction post-procedure is good to excellent at short-term follow-up.
Material and Methods: A retrospective study was conducted in our department from the data collected in the period between 1997 and 2010. There were 86 cases of infected non-union of the tibia, in patients of the age group 18 to 65 years, with a minimum two-year follow-up. Group A consisted of cases treated by ASRL (n=46), and Group B, of cases by IBT (n=40). The non-union following both open and closed fractures had been treated by plate osteosynthesis, intra-medullary nails and primary Ilizarov fixators. Radical debridement was done and fragments stabilised with ring fixators. The actual bone gap and limb length discrepancy were measured on the operating table after debridement. In ASRL acute docking was done for defects up to 3cm, and subacute docking for bigger gaps. Corticotomy was done once there was no infection and distraction started after a latency of seven days. Dynamisation was followed by the application of a patellar tendon bearing cast for one month after removal of the ring with the clinico-radiological union.
Results: The bone loss was 3 to 8cm (4.77±1.43) in Group A and 3 to 9cm (5.31± 1.28) in Group B after thorough debridement. Bony union, eradication of infection and primary soft- tissue healing was 100%, 85% and 78% in Group A and 95%, 60%, 36% in Group B respectively. Nonunion at docking site, equinus deformity, false aneurysm, interposition of soft-tissue, transient nerve palsies were seen only in cases treated by IBT.
Conclusion: IBT is an established method to manage gap non-union of the tibia. In our study, complications were significantly higher in cases where IBT was employed. We, therefore, recommend ASRL with an established protocol for better results in terms of significantly less lengthening index, eradication of infection, and primary soft tissue healing. ASRL is a useful method to bridge the bone gap by making soft tissue and bone reconstruction easier, eliminating the disadvantages of IBT.
