Use of soleus musculocutaneous perforator-based propeller flap for lower extremity wound coverage after osteocutaneous fibula free flap harvest.

BACKGROUND: Osteocutaneous fibula free flap (OCFFF) donor sites are often covered with skin grafts, with an additional donor site, more postoperative care, and increased cost. The authors examine posterior tibial artery (PTA) based pedicled propeller flaps (PPF) as an alternative for OCFFF donor site coverage. PATIENTS AND METHODS: Retrospective review of 16 consecutive patients from 30 to 79 years old, who underwent OCFFF reconstruction of head and neck defects (11 mandibular, 5 maxillary), with the closure of donor site with PPF based on a perforator from PTA. Mean donor site defect measured 12.9 × 5.1 cm, PPF was an elliptical design, and rotated 180 degrees in a propeller fashion, to cover donor site defect. Visual analog scale (VAS) was used to assess esthetic results, functional outcomes assessed using mobility and range of motion (ROM), and secondary complications including infections, hematomas, and seromas were recorded. Follow-up period was noted in months postoperatively. Other information collected included underlying head and neck pathology. RESULTS: Average dimension of PPF measured 13.9 × 4.1 cm. Successful closure of donor site defects in 14 of 16 patients, with two flaps having partial necrosis, one requiring a secondary skin graft. Follow-up was 6 to 10 months, esthetic results with mean VAS 8.8 of 10, full ROM, and mobility noted. No secondary complications were observed. The most common pathology noted was squamous cell carcinoma (6 of 16 patients). CONCLUSION: PPFs based on the soleus branch of the PTA represent an excellent alternative to skin grafts for the closure of OCFFF donor site defects.

Calcified chondroid mesenchymal neoplasm: report of a case involving the temporomandibular joint region and review of the literature.

The calcified chondroid mesenchymal neoplasm (CCMN) represents a recently recognized tumor type with only 50 well-documented cases in the English-language literature. Herein we report an additional case of CCMN presenting as a large mass in the temporomandibular joint region of a 41-year-old female. A review of previously reported cases and the current case of CCMN shows the following features: 1) average age 52 years (range 14-87 years) and an approximately even sex distribution; 2) most frequently involved sites: distal extremities (including foot, hand, wrist, forearm) (n=41) and temporomandibular joint/temporal/parotid region (n=9); 3) multilobular soft tissue tumor with chondroid to cartilaginous matrix, often grungy or lace-like calcifications, and variable cytologic atypia; 4) frequently detected FN1 rearrangement (n=15), including FN1 fusion with FGFR2 (n=7) or other receptor tyrosine kinases; 5) 2 reported local recurrences (after incomplete excision); 6) no reports of malignant biologic behavior.

Comparison of propeller flaps versus skin grafts for coverage of osteocutaneous fibula free flap donor site defects.

BACKGROUND: Authors compare use of propeller flaps versus skin grafts in defect coverage after fibula flap harvest. MATERIALS AND METHODS: Retrospective review of patients who received either PFPF or STSG. Primary predictor variable was technique, and secondary predictor variables were comorbidities. Primary outcome variable was flap/graft healing, and secondary outcome variables were cosmesis, adverse events, effect on activities of daily living (ADLs), pain, additional procedures, and cost. Statistical analysis performed via independent sample t tests, ANOVA, and χ2 tests. Logistic regression analysis was performed. RESULTS: Study sample was 50 patients. PFPFs showed higher rates of success, while STSG showed increased complications and adverse events. Pain and ADLs significantly affected in STSG group. Cosmesis was better in the PFPF group, and overall cost was significantly higher in STSG group. CONCLUSION: PFPFs show greater success rates, fewer complications, improved cosmesis, less pain, reduced cost compared to STSG for wound coverage after fibula flap harvest.
