Reconstruction of Hemifacial Congenital Giant Nevus with Pre-expanded Scalp Flaps and Deltopectoral Skin Flaps.

BACKGROUND: The hemifacial congenital giant nevus impacts both physical and mental health of the patients. Excision is typically the most suitable option in these situations, but reconstructing the subsequent surgical defects is always a serious challenge. METHODS: Between February 2012 and January 2021, a retrospective review of 4 patients who suffered from hemifacial congenital giant nevus was conducted, and they were treated by pre-expanded scalp flap and deltopectoral flap simultaneously. All patients receive tissue expansion, nevus resection, expanded skin flap transfer, and pedicle division. RESULTS: Four patients with hemifacial congenital giant nevi were successfully treated with no major complications. One patient with a transferred deltopectoral flap experienced distal necrosis of the flap, and healed after dressing changes. No recurrence of the nevus was found during the follow-up period, and the transferred skin flaps match well with facial skin in contour and color. CONCLUSION: This modified pre-expanded scalp flap combined with a deltopectoral flap provides an easy and reliable way for hemifacial reconstruction in patients with a congenital giant nevus.

Application of Various Methods to Evaluate the Postoperative Characteristics of Expanded Pedicled Deltopectoral Flap for Large Facial Scars.

ABSTRACT: The expanded pedicled deltopectoral flap (EPDF) has been widely used to repair large facial scars. Although doctors and patients are usually satisfied with the outcomes, the actual functional recovery and cosmetic effects of EPDF are still unknown. It is, therefore, necessary to objectively investigate the effect of transferred EPDF by using a variety of methods. From January 2008 to December 2018, 52 patients who underwent EPDF surgery at Xijing Hospital were enrolled. Sense of touch, static 2-point discrimination, elasticity, and color were measured. Thermesthesia and algesthesia were also tested. Postoperative scars were evaluated using the patient and observer scar assessment scale. Satisfaction of patients, doctors, and laypersons was investigated. The algaesthesis, thalposis, and rhigosis scores were 4.7 ±â€Š0.7, 3.7 ±â€Š0.9, and 4.5 ±â€Š0.8, respectively. The tactile score was 0.3 ±â€Š0.2 mN, and 2-point discrimination was 10.1 ±â€Š4.8 mm. L ∗ , a ∗ hemoglobin, and melanin content of the flaps were significantly different when compared with normal skin ( P   <  0.05). The satisfaction of doctors, patients, and laypersons was 88.5%, 71.2%, and 67.3%, respectively. The higher satisfaction of patients was mainly associated with the smaller color difference between the flap and the surrounding skin, and lower patient and observer scar assessment scale score. These results confirm that excellent functional recovery and reliable cosmetic effects are observed when facial scars are repaired with EPDF. The methods used in this study can be applied to the evaluation of functional recovery and cosmetic outcomes of transferred flaps, which may provide a more comprehensive understanding of flap assessment.

A randomized, split-face controlled trial on the safety and effects of microneedle fractional radiofrequency and fractional erbium-doped glass 1,565-nm laser therapies for baggy lower eyelids.

The non-ablative fractional erbium-doped glass 1,565-nm laser (NAFL) and the microneedle fractional radiofrequency (MFR) procedures are effective treatments that enable periorbital skin rejuvenation. To compare the clinical effectiveness and side effects of MFR and the NAFL for baggy lower eyelids (BLEs) in the Chinese population. Fifteen Chinese subjects with BLEs received three split-face treatments on a monthly basis randomly. Objective and subjective assessments were performed at baseline, as well as 1 month and 3 months after the third treatment. The results were evaluated using Antera-3D and CineScan systems. Blinded investigator assessments were performed by two plastic surgeons using a 0 to 4 score in six anatomic categories of BLEs. The patients also reported their level of satisfaction based on a four-point score. Most of the patients reported a greater than 47% satisfaction rate with both treatments. The cumulative contribution scores of prolapse of orbital fat, hollow tear trough, and skin laxity for each category variable declined with time. Using Antera 3D, the volume of elevation (mm3) decreased from 0.6 ± 0.4 to 0.4 ± 0.3 and from 0.6 ± 0.3 to 0.3 ± 0.3, the elevation area (mm2) decreased from 17.0 ± 8.4 to 13.0 ± 7.1 and from 17.0 ± 7.8 to 10.0 ± 5.6, and the maximum peak height (mm) also decreased from 0.10 ± 0.04 to 0.06 ± 0.04 and from 0.10 ± 0.03 to 0.06 ± 0.02 in the MFR and NAFL groups, respectively. Using CineScan, the depth of middle orbital fat (mm) decreased significantly from 10.2 ± 2.2 to 8.0 ± 0.7 and from 9.8 ± 1.1 to 8.0 ± 0.9 and the length of orbital fat significantly decreased from 9.2 ± 1.2 to 7.7 ± 0.7 and from 9.7 ± 1.4 to 7.8 ± 0.6 in the MFR and NAFL groups, respectively. MFR and NAFL therapies were effective for the treatment of BLEs, especially in BLE patients with skin elasticity in addition to tear trough deformity and orbital fat prolapse.

Latissimus Dorsi-Myocutaneous Flap in the Repair of Titanium Mesh Exposure and Scalp Defect After Cranioplasty.

Titanium mesh was widely used for cranium defect repair but associated with high complication rates. In this study, the authors describe a method using latissimus dorsi-myocutaneous flap in the repair of titanium mesh exposure and scalp defect after cranioplasty, and the plate retaining is also achieved. Fifteen patients from April 2012 to May 2016 underwent this procedure, the age ranged from 32 to 62 years and 47 years old on average, and all the patient had plate exposure combined with surgical site infection and variation of scalp defect. All the patients had fully flap survive, and follow up ranged from 6 months to 24 months, 1 patient had titanium mesh re-expose and received additional operation to remove the plate. The free latissimus dorsi musculocutaneous flap could supply large size of bulky tissue coverage with good blood supply and strong anti-infection ability. This method was an option for retaining the titanium mesh and repairing the exposure for the mild infection with small size scalp defect patient.

The pre-expanded subclavicular island flap: A new tool for facial reconstruction.

BACKGROUND: The anterior chest is an excellent donor site for cervicofacial reconstruction. Studies of chest flaps began as early as 1988 at our institution. We identified a new branch of the supraclavicular artery that nourishes the anterior chest, and on the basis of this finding, we created a new flap called the subclavicular flap. Unlike the supraclavicular flap, which is pedicled by the deltoid branch, this flap is primarily pedicled by the thoracic branch, and it shares similar vascular territory with the deltopectoral flap. In China, this flap has been widely used for neck reconstruction since our first publications on it in 1993. However, reports of its application are limited. To popularize the use of this flap, we present our experiences with pre-expanded subclavicular island flaps for the repair of facial scars. METHODS: Fifteen patients with facial scars underwent reconstruction with these flaps. All flaps underwent pre-expansion before being transferred to the face through a subcutaneous tunnel. The pivot point was in the supraclavicular region and allowed the flap to reach the mid-face without compulsive positioning. Donor sites were closed primarily. RESULTS: Flaps sizes ranged from 4 cm × 5 cm-10 cm × 17 cm. Fourteen flaps survived completely with satisfactory colour and texture. Total flap loss occurred in one patient, who was then treated by harvesting a skin graft from the dying flap. One patient experienced venous congestion, and the flap was successfully salvaged by pure vein anastomosis. CONCLUSION: Pre-expanded subclavicular island flaps have similar benefits to supraclavicular and deltopectoral flaps, and they may emerge as one of the best choices for cervicofacial reconstruction globally.

[The design of the expanded flap for the repair of the temporal and cheek area].

OBJECTIVE: To explore the design of an expanded flap at the temporal and cheek area. METHODS: The expanded flap was used for the repair of 619 temporal and cheek defects secondary to scar, nevus or hemangioma excision. In the frontal area, the rotational flap was usually used. For the repair of the cheek, the applied flap included the rotational, advanced, and transposition flap from the neck, as well as the pedicle flap from the thoracic area. RESULTS: Eight thoracic-deltoid flaps had distal necrosis of 1 approximately 5 cm. Of them, 5 flaps were repositioned with subsequent good result; the other 3 flaps underwent skin grafting. The five facial expanded flaps showed distal necrosis of 0.5 approximately 1 cm. Of them, 4 flaps occurred delayed healing, 1 flap underwent skin grafting. Expander extrusion happened in 41 cases (6.62%), which resulted in deficiency of the expanded area. Satisfactory results were achieved in all the other cases. CONCLUSIONS: According to our experience, careful design of the flap is very important for obtainingbetter surgical results and decreasing complications.
