Clinical application of perforator vessel location guide plate for fibular musculocutaneous flaps / 口腔疾病防治

Objective@#Based on 3D printing technology, explore the precision of a perforator vessel location guide plate for fibular musculocutaneous flaps before the transplantation of fibular osteocutaneous flaps and evaluate its application effects.@*Methods@#This study was reviewed and approved by the ethics committee, and informed consent was obtained from the patients. From May 2019 to October 2022, 14 patients with jaw defects who needed to undergo fibular perforator flap transplantation at the First Affiliated Hospital of Xinjiang Medical University were selected. For the seven patients in the guide plate group, CTA was combined with Mimics software to reconstruct both lower limbs, and the perforator vessel positioning guide for locating perforator vessels was designed; the two ends of the guide plate were designed as fixed ends, with the upper end fixed to the knee joint and the lower end fixed to the ankle joint, and the guide plate was fabricated by a 3D printer. For the seven patients in the control group, a conventional handheld Doppler probe was used for perforator vessel location. The average operation time, bleeding volume, recovery time, deviation of perforator vessel location, postoperative flap-related complications, postoperative donor site shape satisfaction, and lower extremity functional scale (LEFS) score were recorded. SPSS 25.0 software was used for statistical analysis.@*Results@#The average operation time, bleeding volume, recovery time, deviation of perforator vessel location and postoperative donor site shape satisfaction were significantly better in the guide plate group than in the control group (P<0.05); moreover, the differences in postoperative flap-related complications and LEFS scores were not statistically significant (P>0.05).@*Conclusion@#Based on 3D printing technology, fibular musculocutaneous flap perforator vessels can be more accurately located using a guide plate and the knee and ankle as fixed points, and this method can effectively stabilize the guide position, prevent soft tissue offset, and improve positioning accuracy and thus deserves to be generalized.

Removal of benign tumor in the lower pole of the parotid gland through concealed incision in the retroauricular sulcus / 口腔疾病防治

Objective @#To assess the safety and feasibility of incision in the retroauricular sulcus for removal of benign tumors in the lower pole of the parotid gland and to provide some ideas for aesthetic consideration of parotidectomy.@*Methods@# In total, 18 cases with benign tumors of the lower pole regions of the parotid gland were included in this study, including 9 pleomorphic adenomas, 2 myoepitheliomas, 5 Warthin tumors, 1 basal cell adenoma and 1 oncocytoma. Three months after the operation, facial paralysis and salivary fistula were assessed. A visual analog scale was used to score the cosmetic satisfaction of the surgical incision. Tumor recurrence was followed up 6 ~ 12 months after operation.@*Results@# In 18 patients with benign tumors the lower pole regions of the parotid gland, the tumor diameter ranges from 1.0 to 3.1 cm, with an average value of 2.5 cm. All patients experienced successful complete removal of the parotid mass with the minimally invasive retroauricular approach, and all wounds healed in one stage after operation. No serious complications, such as permanent facial paralysis and tumor recurrence, occurred 3 months after the operation. The patients were satisfied with the appearance of the surgical incision (aesthetic score 9.3 ± 0.4), achieving the expected aesthetic effect. @*Conclusion@#This approach is feasible and safe for most small benign parotid tumors located in the lower pole region of the parotid gland and in the posterior region of the jaw. The scar is located in the retroauricular sulcus, which significantly meets the aesthetic needs of the concealed incision for patients.

ABSTRACT Introduction: In tetraplegic persons, the lack of function of the upper limb constitutes the utmost barrier to their autonomy, which is why many of them consider the reconstruction and recovery of their upper limbs to be very important. Objective: To describe the restoration of the caliper and the grip of quadriplegic hand with the use of Zancolli and House techniques. Method: A longitudinal, prospective study was carried out in 12 tetraplegic patients who came to the upper limp consultation at Frank País International Orthopedic Scientific Complex, from January 2013 to December 2016. The study variables were age, sex, injury etiology, classification (according to Giens international classification), dependence on daily activities (Barthel index), function of the limb (Mowery functional classification), personal satisfaction (Allien and Machle scale) and complications. Zancolli and House techniques were used. The information was collected from the medical records of the admitted patients. Data was processed in a microcomputer database with Word and Excel systems. The SPSS 17 statistical system was also used. Results: Eleven men and one woman (24 hands in total) were treated from the total of patients in the sample. The average age was 30 years, with 8.6 years of latency period. Traumatic spinal cord injury was collected as the etiology of the spinal cord injury. According to the international Giens classification, there were ten patients in group 4, and two patients in group 5. Complications occurred in three cases. With surgery, all patients were able to change from dependent to independent status. Regarding hand function, the vast majority of the sample was classified as excellent, and regarding personal satisfaction, nine patients reported feeling excellent. Conclusions: Zancolli and House techniques favor the restoration of the caliper and the grip of the quadriplegic hand, improve joint mobility, muscle strength and the functionality of the hand.
