Evaluation of natural growth rate and recommended age for shaving procedure by volumetric analysis of craniofacial fibrous dysplasia.

BACKGROUND: We evaluated the preoperative natural growth pattern of craniofacial fibrous dysplasia and postoperative volume changes in patients undergoing shaving procedures. METHODS: Thirty-three patients who underwent serial computed tomography (CT) preoperatively and/or postoperatively were identified. The natural tumor growth rate was assessed using preoperative CT scans. The postoperative tumor regrowth rates and relevant variables were analyzed. RESULTS: The preoperative tumor growth rates were significantly lower in patients aged ≥ 16 years than in those aged < 16 years (P < .001). The postoperative tumor regrowth rates were significantly greater when a shaving operation was performed at age < 16 years than at age ≥ 16 years (P = .04). In patients with clinical recurrence, the postoperative remnant tumor volume was inversely correlated with the tumor regrowth rate. CONCLUSIONS: The tumor growth rate of craniofacial fibrous dysplasia significantly decreased after age 16. This should be considered when conducting functional and aesthetic assessments in planning for the shaving of craniofacial fibrous dysplasia.

Comparative Study of Nipple-Areola Complex Position and Patient Satisfaction After Unilateral Mastectomy and Immediate Expander-Implant Reconstruction Nipple-Sparing Mastectomy Versus Skin-Sparing Mastectomy.

BACKGROUND: Major surgical concerns associated with nipple-sparing mastectomy (NSM) are partial or total nipple-areola complex (NAC) loss, decreased sensation, and nipple malposition. Patient satisfaction and NAC outcomes including malposition in patients who have undergone unilateral expander-implant reconstruction after NSM as compared with skin-sparing mastectomy (SSM) remain unclear. Therefore, the aim of this study was to assess patient satisfaction and NAC outcomes of breast cancer patients who underwent spared or reconstructed NAC after unilateral NSM as compared with unilateral SSM. METHODS: Patients who underwent immediate expander-implant breast reconstruction following unilateral NSM or SSM were included. Medical records of patients from April 2010 to February 2014 were retrospectively reviewed. Reconstruction-related complications such as infection, seroma, haematoma, delayed wound healing, and reconstruction failure were recorded. NAC outcome analysis was performed using preoperative and postoperative digital photographs for each patient. Patient satisfaction with the reconstructed breast and NAC was assessed using a study-specific questionnaire. RESULTS: Delayed wound healing occurred in 18 of 55 NSM patients and 15 of 85 SSM patients (p = 0.040). Final reconstruction failure occurred in 0 NSM patients and 6 SSM patients (p = 0.043). The mean photography analysis score of total aesthetic outcome was 13.12 ± 2.39 in the NSM group and 14.06 ± 2.75 in the SSM group (p = 0.052). The mean questionnaire score of NAC position was 2.88 ± 0.85 in the NSM group and 3.80 ± 0.84 in the SSM group (p = 0.001). The mean questionnaire score of NAC sensitivity was 2.12 ± 0.58 in the NSM group and 1.84 ± 0.46 in the SSM group (p = 0.003). Satisfaction with the reconstructed breast was similar (p = 0.913) after NSM and SSM. CONCLUSIONS: We observed no significant difference in breast reconstruction satisfaction between the NSM and SSM groups. Although overall satisfaction with breast reconstruction is high, patients in the NSM group often report dissatisfaction with nipple position. With a favourable score for NAC position, skin-sparing mastectomy followed by NAC reconstruction can be considered as a balanced alternative to NSM for properly selected patients with breast cancer.

The Use of Magnetic Resonance Imaging in Planning a Pedicled Perforator Flap for Pressure Sores in the Gluteal Region.

Pedicled perforator flaps (PPFs) have been widely used to treat pressure sores in the gluteal region. Selection of a reliable perforator is crucial for successful surgical treatment of pressure sores using PPFs. In this study, we evaluate the role of magnetic resonance imaging (MRI) in planning PPF reconstruction of pressure sores in the gluteal region. A retrospective chart review was performed in patients who had undergone these PPF reconstructions and who had received preoperative MRI. Preoperatively, the extent of infection and necrotic tissue was evaluated using MRI, and a reliable perforator was identified, considering the perforator location in relation to the defect, perforator size, and perforator courses. Intraoperatively, the targeted perforator was marked on the skin at the locations measured on the MRI images, and the marked location was confirmed using intraoperative handheld Doppler. Superior gluteal artery, inferior gluteal artery, or parasacral perforators were used for the PPFs. Surgical outcomes were evaluated. A total of 12 PPFs were performed in 12 patients. Superior gluteal artery perforator flaps were performed in 7 patients, inferior gluteal artery perforator flaps were performed in 3 patients, and parasacral perforator flaps were performed in 2 patients. We could identify a reliable perforator on MRI, and it was found at the predicted locations in all cases. There was only one case of partial flap necrosis. There was no recurrence of the pressure sores during the mean follow-up period of 6.7 months (range = 3-15 months). In selected patients with gluteal pressure sores, MRI is a suitable means for not only providing information about disease extent and comorbidities but also for evaluating perforators for PPF reconstructions.

A new technique for transcutaneous fixation of the costal cartilage block utilized in reconstructed ear elevation for microtia.

PURPOSE: With the aim of implementing good projection of the three-dimensional frame (auriculo-cephalic angle) and maintaining projection, a significant issue during the stage of auricular elevation for avoiding the potential for dislodging the cartilage blocks remains. Herein we present an innovative and technically simple method of transcutaneous fixation of the costal cartilage block during the stage of auricular elevation. MATERIALS AND METHODS: After elevation of ear frame from the basement, two suspension stitches on the surface of the elevated ear were used to fix the embedding cartilage block into the auriculo-cephalic sulcus at the upper (bifurcation point of the anti-helix where the inferior and superior crus meet to form the triangular fossa) and lower (projection point of the concha wall, parallel to the level of the tragus) ones. A loop of suture was placed through a dermal anchor, ear frame, and piece of the cartilage block. RESULTS: Among a total of 50 patients, 94% achieved 'excellent' and 'good' outcomes in terms of auricular symmetry. Likewise, 86% (n = 43) of patients achieved 'excellent' and 'good' outcomes in terms of projection in postoperative 6- month follow-up. There were no instances of significant cartilage or knot exposure or absorption of the embedded cartilage blocks. CONCLUSION: The technique of transcutaneous fixation of cartilage blocks for ear elevation described in this study was associated with excellent outcomes, producing stable clinical results based on our long-term experience with ear reconstruction.

Reconstruction Outcomes of Oncologic Foot Defect Using Well-Contoured Free Perforator Flaps.

BACKGROUND: Reconstruction of foot defects following oncologic resection is a crucial element in the treatment of soft tissue malignancy of the foot. OBJECTIVE: The present study aimed to comprehensively evaluate outcomes of oncologic foot reconstruction using free perforator flaps. METHODS: Outcomes of patients with soft tissue malignancy of the foot who underwent reconstruction using a free perforator flap following ablative surgery were reviewed, and perioperative and delayed complications (secondary debulking operation and flap instability) were documented. The Foot Function Index (FFI) questionnaire was surveyed to assess functional status. RESULTS: Overall, 72 patients were analyzed, with a median follow-up period of 28 months. Malignant melanoma was a predominant etiology. Three kinds of perforator flaps were used, with the thoracodorsal artery perforator flap being the most common. Flaps with skin dimensions matching the defect size were inset and the thickness of the flaps was controlled with primary defatting. Flap re-exploration was conducted in 11 (15.2%) cases and total flap loss occurred in 3 (4.2%) cases. Delayed complications developed in an additional 12 cases, therefore 23 (31.9%) cases required a return to the operating room. The average FFI score was 8.86 at postoperative month 36, on average (range 11-128 months). All respondents reported being independently ambulatory and had minimal difficulty in their daily lives. Reconstruction of defects on weight-bearing regions showed a significantly higher FFI score than that on nonweight-bearing regions (mean 11.96 vs. 4.79, p = 0.029), although the scores remained very low for both instances. CONCLUSIONS: Oncologic foot defects can be reliably reconstructed using well-contoured free perforator flaps with minimal functional morbidity.

Does the Use of Incisional Negative-Pressure Wound Therapy Prevent Mastectomy Flap Necrosis in Immediate Expander-Based Breast Reconstruction?

BACKGROUND: Mastectomy flap necrosis is one of the most common and significant complications in immediate expander-based breast reconstruction. Negative-pressure wound therapy is widely used for open wounds but is not commonly used for closed incisional wounds. However, the postoperative use of incisional negative-pressure wound therapy is demonstrated to reduce complication rates. The authors evaluate the incidence of mastectomy flap necrosis in patients with incisional negative-pressure wound therapy after immediate expander-based breast reconstruction compared with the incidence in patients with conventional dressing. METHODS: A retrospective review was conducted to identify patients who underwent immediate expander-based breast reconstruction between January of 2010 and February of 2015 at a single institution. Patients were divided into a conventional dressing group and an incisional negative-pressure wound therapy group. Patient demographics, intraoperative findings, and complications were compared between the two groups. RESULTS: A total of 228 breasts (206 patients) were included in this study. Of these, the incisional negative-pressure wound therapy group included 45 breasts (44 patients) and the conventional dressing group included 183 breasts (162 patients). The incisional negative-pressure wound therapy group had a lower overall complication rate (11.1 percent versus 27.9 percent; p = 0.019), overall mastectomy flap necrosis rate (8.9 percent versus 23.5 percent; p = 0.030), and major mastectomy flap necrosis rate (2.2 percent versus 13.7 percent; p = 0.031) compared with the conventional dressing group. CONCLUSIONS: Incisional negative-pressure wound therapy reduced the incidence of mastectomy flap necrosis. This simple and reliable dressing technique can be effective in preventing mastectomy flap necrosis in immediate expander-based breast reconstruction.
