Columella reconstruction using double nasolabial flap and costal cartilage: A case report.

ABSTRACT: Total loss of columella causes significant aesthetic and functional deformities due to its important functions which provides assistance and extension to the nose pointer. Noma is described as one of the developed sources of total columellar loss, and is also contagious, with the ability to intensely damage facial tissues and immediate structures. However, the condition is predominantly suffered in Africa, with an estimation of 20 instances per 100,000 individuals. Furthermore, the reformation of a columellar disorder offers a complex process, due to the structural features of the location. A 24-year-old female patient with total columellar loss caused by Noma. We performed a two stage reconstruction. First, we used double nasolabial flaps to create a new columella. Second, we inserted costal cartilage and dermofat graft to support it. The double nasolabial flap demonstrated 100% survival. Both nasal airway and the final appearance showed functionally and cosmetically remarkable results. The nasolabial angle projected better than the preoperative measurement. The patient was satisfied. The patient was followed up until a year after surgery. The double nasolabial flaps combined with costal cartilage graft is one of the best surgical options to obtain astonishing columellar reconstruction.

Project description:The blood supply pattern of the partial-thickness musculomucosal pedicle flaps is different from the traditional Abbe flap. The arterial blood supply and venous drainage are highly reliable during clinical practice.To describe the reconstruction of the philtrum in the cross-lip flap transfer using nasolabial muscle tension line group reconstruction.From January 1, 2014, through June 31, 2015, a total of 6 patients with upper lip defect were treated with philtrum reconstruction in the same stage of the split cross-lip flap transfer at the Plastic Surgery Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China. These patients underwent reconstruction of the philtrum by nasolabial muscle tension line group reconstruction. The patients were compared with a randomly chosen group of 5 individuals without upper lip defects by measuring the 3-dimensional scans.In the patient group, the split flap was elevated from the posterior portion of the oris orbicularis muscle after the inferior labial arteries were divided. Then the partial-thickness flap was rotated 180° horizontally and inverted 180° upward to the upper lip defect. The philtrum was reconstructed using the nasolabial muscle tension line group reconstruction.Three-dimensional scans were performed from the 2-month to 28-month revisits.A total of 11 individuals were included in the study: 6 in the patient group (mean [SD] age, 17.0 [4.8] years; 2 [33.3%] female and 4 [66.7%] male) and 5 in the control group (mean [SD] age, 15.2 [6.0] years; 2 [40.0%] female and 3 [60.0%] male). In the patient group, 5 of 6 musculomucosal pedicle flaps were viable. A stable philtrum with philtral ridge and philtral dimple was reconstructed on the 5 flaps. The shape of the philtrum was natural according to the 3-dimensional scan measurement. One flap partially necrosed, and the scar retraction was severe postoperatively.The blood supply of the partial-thickness cross-lip flap was from the small vascular network of the lower lip. It is reliable to reconstruct a philtrum in this stage of flap transfer. A complete philtrum structure can be reconstructed by applying muscle tension on the flap.4.

Project description:We present the cases of 2 patients with invasive thyroid cancer, who underwent reconstructive surgery using a deltopectoral flap. Although the overall rate of extrathyroidal extension in patients with thyroid cancer is quite low, skin invasion is the most common pattern observed. Reconstructive surgery, involving local skin flaps, is required in these patients. The deltopectoral flap relies on the blood supply from intercostal perforators of the internal thoracic artery and usually requires skin grafting to the donor site. The internal thoracic artery is rarely sacrificed in these cases, even in an advanced surgery such as in patients with invasive thyroid cancer.A 55-year-old man with a distended thyroid gland presented to our hospital. He underwent advanced surgery, including skin excision, because we suspected that his tumor was thyroid cancer. The defect was covered with an ipsilateral deltopectoral flap via transposition of the flap, without skin grafting. In the second case, a 67-year-old woman with thyroid cancer that metastasized to her neck lymph nodes presented to our institution. Although the ipsilateral internal thoracic artery was sacrificed near its origin during tumor resection, the deltopectoral flap was raised in the usual manner without any complications. The skin defect caused by the tumor resection was covered with the flap. The patient had an uneventful clinical course for more than 2 years of follow-up. These 2 cases show the effectiveness of using the deltopectoral flap as a reconstructive option for patients with thyroid cancer who underwent radical surgery, resulting in a skin defect. The first case shows that this flap does not always require skin grafting to the donor site. To our knowledge, the second case may be the first report of a deltopectoral flap that was safely raised and applied with resection of the bifurcation of the ipsilateral internal thoracic artery.Although thyroid cancer surgery with surrounding skin excision is a rare procedure, we found that the deltopectoral flap was useful and should be the first choice for patients undergoing reconstructive surgery, whether the bifurcation of the ipsilateral internal thoracic artery is sacrificed.
