Dynamic Reconstruction Using Bilateral Lengthening Temporalis Myoplasty for Facial Palsies in Patients with Hereditary Skin Laxity.

Hereditary skin laxity is a rare condition, some cases of which are also referred to as cutis laxa, and those involving facial skin are considered a target for treatment by plastic surgery as patients present with an aged face, which can reduce their quality of life. In some of these patients, the facial nerve and muscles may be affected, and cause weakness of mimetic muscles. We performed one-stage bilateral lengthening temporalis myoplasty reanimation, followed by lower facial contouring with partial lower lip excision and hammock-shaped fascia grafting in two patients with hereditary facial skin laxity coexisting with facial palsy. The patient was a 63-year-old woman with hereditary gelsolin amyloidosis and a 64-year-old man who was diagnosed with oculopharyngeal muscular dystrophy. Postoperatively, a symmetrical facial contour was achieved in repose, and smiling with and without biting was possible. To our knowledge, there are no reports of dynamic smile reconstruction for facial weakness in patients with hereditary facial skin laxity. Although these patients may experience progressive loss of function of the trigeminal nerve and its innervating muscles, the static suspension effect of lengthening temporalis myoplasty can be expected to continue even if the temporal muscles lose their function in the future. We believe that, with careful patient selection, dynamic reconstruction is an option for progressive facial paralysis. In this article, we present the chronological history of two patients who underwent multiple plastic surgery procedures and discuss the importance of the role of plastic surgery in improving the quality of life under these conditions.

Cranial Reconstruction Using Antibiotic-Impregnated Calcium Phosphate Bone Cement With a Titanium Mesh Sheet.

BACKGROUND: The authors treated skin ulcer accompanied by cranial osteomyelitis using a combination of antibiotic-impregnated calcium phosphate bone cement (Biopex; Pentax, Tokyo, Japan) and a titanium mesh sheet (3D Mesh Plate; Bear Medic, Tokyo, Japan). METHOD: A 71-year-old male was treated with superficial temporal artery-middle cerebral artery bypass surgery for diffuse cerebral infarction and obstruction of the left internal carotid artery by a previous doctor. Skin necrosis and epidural abscess developed in the sutured region after surgery, and ulcer accompanied by temporal bone exposure remained. Thus, the patient transferred to our department. A bone defect formed by debridement and sequestrectomy was measured at 4.5 × 8 cm (30 cm). Methicillin-resistant Staphylococcus aureus was detected on wound culture test. Cranioplasty with a combination of calcium phosphate bone cement impregnated with teicoplanin, to which the causative bacteria showed high sensitivity, and a titanium mesh sheet and scalp reconstruction with a free rectus abdominis musculocutaneous flap were performed. RESULTS: As of 6 months after surgery, no infection has relapsed and no complication, such as resorption of the calcium phosphate bone cement and breakage of the titanium mesh sheet, was noted on postoperative computed tomography. CONCLUSION: The authors performed cranial reconstruction with a combination of teicoplanin-impregnated calcium phosphate bone cement and a titanium mesh sheet in a patient with Methicillin-resistant Staphylococcus aureus infection-induced skin ulcer accompanied by cranial osteomyelitis and achieved subsidence of infection. Drug-impregnated calcium phosphate bone cement has a problem with strength, but combination with a titanium mesh sheet as an auxiliary support material enables application to relatively extensive cranial full-thickness defects and it may be a useful treatment method.

Use of Parotid Gland Fascia in the Prevention of Frey Syndrome After Parotidectomy.

BACKGROUND: Superficial parotidectomy is standard surgical procedure for parotid gland tumor, and Frey syndrome and depressed deformity of the region are often seen as complications. In this study, we performed prevention of Frey syndrome by covering the residual parotid gland defect with the parotid gland fascia flap. METHOD: The subjects were 5 patients with parotid gland tumor. Tumor was localized in the inferior and superior poles of the parotid gland in 3 and 2 patients, respectively, and it was confirmed on preoperative diagnostic imaging that the tumor and parotid gland fascia were not present in close proximity. Through Lazy-S incision, main trunk of facial nerve was identified and conserved following the surgical procedure of normal superficial parotidectomy, and the superficial parotid gland containing tumor was elevated. A parotid gland fascia flap with a pedicle on the nasal side was prepared and the defect after superficial parotidectomy was covered with it. RESULTS: The facial nerve and resected parotid gland stump could be sufficiently covered with the parotid gland fascia flap in all patients. The mean duration of postoperative follow-up was 36 months (10 months-4 years and 5 months), and there were no complications such as tumor recurrence, Frey syndrome, salivary gland fistula, or severe concavity in the parotid region. CONCLUSION: Although application of the present procedure is limited to patients in whom the parotid gland fascia and tumor are not located in close proximity, it may be useful to prevent Frey syndrome because extension of incision is not necessary, the surrounding tissue is not sacrificed, the flap can be easily elevated, and the parotid gland stump can be sufficiently covered.

Primary Reconstruction After Maxillectomy Defects Using Ultra Flex Mesh Plate and Rectus Abdominis Myocutaneous Free Flap Including Aponeurosis of External Abdominal Oblique Muscle.

BACKGROUND: In primary reconstruction after maxillectomy for cancer, simple and less invasive surgical techniques considering functionality and aesthetics are necessary. The authors performed reconstruction for tissue defects after maxillectomy using an Ultra flex mesh plate and a free rectus abdominis myocutaneous flap including the aponeurosis of the external abdominal oblique muscle. METHOD: A 72-year-old male with a maxillary squamous cell carcinoma underwent subtotal maxillectomy. For maxillary defects, including those in the orbital floor and hard palate, the authors performed rigid reconstruction using an Ultra flex mesh plate produced after simulation surgery using a 3-dimensional solid model, and palatal and soft tissue reconstruction using a free rectus abdominis myocutaneous flap including the aponeurosis of the external abdominal oblique muscle. After screw fixation of the mesh plate at the surrounding normal bone, the skinpaddle of the rectus abdominis flap was transferred to the oral defect. The surface of the mesh plate was completely covered with the aponeurosis of the external abdominal oblique muscle, and the remaining rectus abdominis flap was inserted into the maxillary sinus. RESULTS: At present, 1 year after the operation, there is no recurrence, complications, such as infection, or titanium mesh breakage/exposure, and his facial shape is favorably maintained. CONCLUSION: Reconstruction using this method is simple and less invasive. Postoperative infection and plate exposure were prevented by the complete coverage of the mesh plate with the aponeurosis of the external abdominal oblique muscle and flap. Mesh plates, when properly used, are useful reconstruction materials, but are susceptible to infection compared with autologous tissue, requiring long-term follow-up.

Modified Lengthening Temporalis Myoplasty Involving an Extended Lazy-S Incision to Avoid Facial Scar Formation.

BACKGROUND: Lengthening temporalis myoplasty is a faster and less invasive alternative to free muscle transfer for smile reconstruction. However, it requires a nasolabial fold incision, which leaves a midfacial scar. Based on esthetic considerations, a modified approach, involving an extended lazy-S (parotidectomy) incision instead of a nasolabial fold incision, was developed. METHODS: A cadaveric study involving 10 hemifaces was conducted. From February 2013 to March 2016, the modified lengthening temporalis myoplasty procedure was employed in 10 patients. The results were graded from 1 (poor) to 5 (excellent) according to the Terzis grading system. The excursion of the oral commissure was also measured. RESULTS: The extended lazy-S incision provides easy and safe access to the coronoid process and good visibility. The patients' mean age was 56.5 years, and the mean duration of the postoperative follow-up period was 22.2 months. The patients' underlying conditions included acoustic neuroma (n = 2), Bell palsy (n = 3), congenital conditions (n = 2), brain infarction (n = 1), Ramsay Hunt syndrome (n = 1), and malignant parotid lymphoma (n = 1). One patient suffered a surgical site infection, which was successfully treated with irrigation. All the patients achieved improvements in smile symmetry: 2, 5, and 3 patients obtained excellent, good, and moderate results, respectively. The excursion of the oral commissure ranged from 5 to 10 mm. CONCLUSION: The modified lengthening temporalis myoplasty procedure provides satisfactory functional outcomes without causing significant complications. It does not leave a facial scar and is a preferable option, especially for young and female patients, and patients who have undergone ablative surgery involving the parotid region.

Unit Advancement Flap for Lower Lip Reconstruction.

BACKGROUND: Lower lip reconstruction requires consideration of esthetic and functional outcome in selecting a surgical procedure, and reconstruction with local tissue is useful. The authors reconstructed full-thickness defects with a unit advancement flap. METHODS: Reconstruction was performed using this method in 4 patients with lower lip squamous cell carcinoma in whom tumor resection with preservation of the mouth angle was possible. The lower lip resection width was 30 to 45 mm, accounting for 50% to 68% of the entire width of the lower lip. The flap was prepared by lateral extension from above the mental unit and matched with the potential wrinkle line of the lower lip in order to design a unit morphology surrounded by the anterior margin of the depressor labii inferioris muscle. It was elevated as a full-thickness flap composed of the orbicularis oris muscle, skin, and mucosa of the residual lower lip from the bilateral sides, and advanced to the defect. Flap transfer was adjusted by small triangular resection of the skin on the lateral side of the mental unit. RESULTS: The postoperative scar was inconspicuous in all patients and there was no impairment of the mouth opening-closing or articulation functions. CONCLUSIONS: This was a relatively simple surgical procedure. A blood supply of the flap was stable, and continuity of the orbicularis oris muscle was reconstructed by transferred the residual lower lip advancement flap from the bilateral sides. The postoperative mouth opening-closing function was sufficient, and dentures could be placed from an early phase in elderly patients. The postoperative scar was consistent with the lip unit morphology, being esthetically superior. This procedure may be applicable for reconstruction of defects approximately 1/3 to 2/3 the width of the lower lip where the mouth angle is preserved.

Medial canthal reconstruction with multiple local flaps.

BACKGROUND: It is often difficult to reconstruct comparatively large defects in the medial canthal region. The authors have performed reconstruction with multiple local flaps in 4 medial canthal defects after resection of malignant skin tumors. METHOD: The defects exceeded the medial canthal region, extending to the upper eyelid and the lower eyelid. The medial canthal defect was covered by transposition of a glabellar flap, the upper eyelid defect was covered by an upper eyelid myocutaneous advancement flap, and the lower eyelid defect was covered by a cheek rotation flap. Then the donor site of the glabellar flap was covered by a Rintala flap. RESULTS: There was no recurrence in any of the cases, and good results were obtained. One case showed mild linear contracture, but the patient did not want corrective surgery. CONCLUSION: This method is somewhat complicated compared to reconstruction with a single flap, but it is a combination of standard local flaps and is a simple reconstructive procedure. By adding additional resection, the suture line is consistent with the border of the facial unit, so postoperative scarring is inconspicuous. This technique is aesthetically useful because of the continuity of colour and texture resulting from the use of adjacent flaps.

Navigation-Assisted Nasal Bone Osteotomy for Malunited Fracture.

BACKGROUND: Nasal bone osteotomy subjectively judges the position for osteotomy by visual inspection and by manual feel using the fingertip. Therefore, the outcome depends on the surgeon's experience and mastery of the procedure is technically challenging. METHODS: The authors applied a navigation system for the intraoperative evaluation of the osteotomy line and reduction position in 5 patients with malunited nasal bone fracture. The authors performed the operation with a temporal bone post developed for otologic surgery using Stealth Station S7 System (Medtronic, Minneapolis, MN). The suretrack is attached to the bone chisel. The authors performed the osteotomies while visualizing the tip of the chisel on the monitor.In addition, evaluation of the reduction position was performed by insertion of a 23G needle syringe with the suretrack to the nasal bone surface. RESULTS: The tip of the bone chisel was visible on the monitor, and the authors could perform osteotomies while confirming the position and direction of osteotomy. In addition, the reduction position could be visualized clearly on the monitor. CONCLUSION: Navigation systems can confirm the 3-dimensional spatial relationship around the fracture site in real time, requiring only comparatively simple preoperative preparation and intraoperative operation without radiation exposure. Therefore, the advantage is that even an inexperienced surgeon can perform an accurate evaluation. This would be useful as a guide for young doctors and medical students as it would be possible to perform safe and accurate osteotomy for old nasal bone fractures.

Cauliflower-Like Shaped Osteoma.

Skull osteoma is a benign tumor that slowly and continuously enlarges. It is frequently observed in routine medical practice and many patients show an arc shape. The authors encountered a patient with osteoma with a rare morphology that developed in the occipital region. The patient was a 66-year-old male who had been aware of the presence of a mass in the occipital region for about 50 years, but its uncomfortable feeling had recently increased, and it was resected. The excised tumor showed a pedunculated cauliflower-like shape continuous to the skull. The pathological diagnosis was osteoma. The cause of rare morphologies includes trauma and infection, but this patient had no such past medical history. Since the development site was the occipital region, it was assumed that chronic stimulation caused the rare morphology.

Navigation-Assisted Bone Grafting for Blowout Fracture.

BACKGROUND: Treatment of orbital floor fracture accompanied by extensive bone defect requires orbital floor reconstruction using a bone graft, but graft may deviate into the maxillary sinus when no bone capable of supporting the graft remains around the defect. In such cases, it is necessary to fix the grafted bone to the orbital margin, but the grafted bone placement site is subjectively decided based on inspection through a small incision in many cases, being dependent on the experience of operators, and it has been difficult to accurately determine the placement angle. METHODS: The authors applied a navigation system in 4 patients with orbital blowout fracture, and evaluated for the exact bone graft placement angle and orbital floor form during surgery. RESULTS: The bone graft placement angle was evaluated by comparison with a mirror image of the nonaffected side. The angle could be confirmed during surgery, as well as the lateral symmetry of the orbital form. On postoperative computed tomography, the grafted bone was retained at a favorable placement site. CONCLUSIONS: The navigation system may be useful to support the treatment of orbital blowout fracture, as it facilitates safe dissection around orbital floor bone defects, confirmation of the positional relationship between the bone fragment and orbital tissue and bone graft fixation position, and evaluation of lateral symmetry of the orbital floor form during surgery.

Vascular waveform analysis of flap-feeding vessels using color Doppler ultrasonography.

We performed vascular waveform analysis of flap-feeding vessels using color Doppler ultrasonography and evaluated the blood flow in the flaps prior to surgery. Vascular waveform analysis was performed in 19 patients. The analyzed parameters included the vascular diameter, flow volume, flow velocity, resistance index, pulsatility index, and acceleration time. The arterial waveform was classified into 5 types based on the partially modified blood flow waveform classification reported by Hirai et al.; in particular, D-1a, D-1b, and D-2 were considered as normal waveforms. They were 4 patients which observed abnormal vascular waveform among 19 patients (D-4 : 1, D-3 : 1, and Poor detect : 2). The case which presented D-4 waveform changed the surgical procedure, and a favorable outcome was achieved. Muscle flap of the case which presented D-3 waveform was partially necrosed. The case which detected blood flow poorly was judged to be the vascular obstruction of the internal thoracic artery. In the evaluation of blood flow in flaps using color Doppler ultrasonography, determination of not only basic blood flow information, such as the vascular distribution and diameter and flow velocity, but also the flow volume, vascular resistance, and arterial waveform is essential to elucidate the hemodynamics of the flap.

Intraoperative repositioning assessment using navigation system in zygomatic fracture.

BACKGROUND: Intraoperative repositioning assessment in the zygomatic fracture operation is very important in achieving adequate facial symmetry. A navigation system that has been developed in neurosurgery has recently been applied in the otolaryngol, orthopedic, and maxillofacial surgeries. We used a navigation system (Stealth Station TREON; Medtronic) in zygomatic fracture operation, and found it useful in performing accurate reduction and confirming the symmetry. METHODS: We applied a navigation system in 6 patients with zygomatic bone fracture. Navigation aided reduction of the bone fracture was performed by evaluating intraoperative procedures: (1) an evaluation by measuring the distances from the midline of the face and (2) an evaluation by comparing the affected side to the mirror image of the nonaffected side. A method using the distance from the midline of the face was performed in 3 cases, and a method using the mirror image of the nonaffected side was used in 6 cases. RESULTS: Accurate reduction and symmetry were confirmed during the operation in all patients. Good symmetry was confirmed in postoperative computed tomographic scan. It was useful in performing accurate reduction of the fractures and confirming the symmetry of the face. CONCLUSIONS: We suggest that the system can also be applied for the treatment of untreated facial fractures requiring osteotomy and of comminuted facial fractures with third-bone fragments and for the evaluation of bone graft.

Repair of a recurrent rectovaginal fistula using gluteal-fold flap: report of a case.

Various surgical procedures have been reported for the repair of a rectovaginal fistula, but a failure of the initial repair leads to difficulty in the second and later operations. This report presents the case of a 58-year-old woman with a recurrent rectovaginal fistula after a low anterior resection for rectal cancer who achieved a good outcome following a repair using a gluteal-fold flap. We therefore conclude that the transfer of a well-vascularized gluteal-fold flap may be a safe and reliable method to repair a rectovaginal fistula with a large diameter following repeated recurrence.

Medial canthal reconstruction with glabellar combined Rintala flaps.

BACKGROUND: In medial canthal reconstruction, the continuity of color and texture and the reproduction of natural external appearance are required, and reconstruction with a flap adjacent to the defect is frequently performed as the first choice. The authors have performed reconstruction with a glabellar flap combined with a Rintala flap in five patients. METHODS: A glabellar flap, which is rectangular according to the unit principle, was elevated, and after thinning and trimming to the defect shape, was transferred to the medial canthal defect. The donor site of the glabellar flap was closed with a Rintala flap. RESULTS: Reconstruction by means of this procedure was performed in five patients with defects after resection of medial canthal basal cell carcinoma. In one patient with extension of the defect to the upper and lower eyelids, the tip of the glabellar flap was divided into two portions and transferred to the defective site. No recurrence was observed in any patient, and satisfactory results including aesthetic results were obtained in all patients. CONCLUSIONS: This technique can be performed readily and is applicable to the reconstruction of relatively large defects and is also aesthetically excellent because of a postoperative suture line that is consistent with the topographic curve. This technique may be useful for medial canthal reconstruction.

Locally advanced and metastatic breast cancer with cartilaginous and/or osseous metaplasia showing excellent response to chemotherapy.

Breast cancer with cartilaginous and/or osseous metaplasia is considered a rare disease, but several cases have been reported recently. We report a case of breast cancer with cartilaginous and/or osseous metaplasia that was StageIV,(T4bN0M1b (PUL)), on the basis of the Japanese General Rules for Clinical and Pathological Recording of Breast Cancer, which responded well to chemotherapy. A 58-year-old women visited our hospital with a chief complaint of a palpable breast mass that had increased in size in March 2002. It was 20 x 15 x 14 cm and occupied the entire right breast. Chest computed tomography (CT) demonstrated multiple lung metastases. Histology of the biopsy specimens revealed a spindle-shaped cell carcinoma. It was ER(-), PgR(-), and HER2/neu Score 0. CAF was given to the patient as preoperative chemotherapy. Five cycles of treatment yielded improvement at the primary site and improvement of the metastatic lung lesions, which was judged as a partial response. Subsequently, one cycle of weekly paclitaxel 80 mg/m2 and oral administration of 5'-DFUR 800 mg/day were given. In November 2002, the patient underwent a right simple mastectomy with whole-layer skin grafting from the abdomen. The final pathological diagnosis was a rare type of breast cancer with cartilaginous and/or osseous metaplasia. Preoperative chemotherapy had caused necrosis in most of the tumor cells, and the efficacy was judged as Grade 2. From the third week postoperatively, weekly paclitaxel (80 mg/m2) was given. Six months after the operation, the multiple lung metastases were completely eliminated and new metastasis to liver or bone or local recurrence have not been observed.

A case of breast cancer metastasizing to cervix after resection of pancreatic metastasis.

A case of breast cancer that metastasized to the cervix 10 years and 8 months after mastectomy is reported. The patient had undergone pancreaticoduodenectomy due to solitary metastasis to the head of the pancreas 4 years previously. The cervical metastasis was associated with abnormal genital bleeding. After pancreaticoduodenectomy the serum levels of CEA, CA15-3 and NCC-ST-439, which are markers of breast cancer, were within normal limits, but the serum level of CA15-3 had increased month by month. The patient had abnormal genital bleeding and presented to the department of gynecology at our hospital. The tumor was in the cervix, bled easily and 2.5x2.0 cm in size on ultrasonography. It was thought to be carcinoma of the cervix, but biopsy revealed the tumor to be an adenocarcinoma pathologically and CA15-3 was immunohistochemically demonstrated in the resected specimen, similar to lobular carcinoma of the breast. Abdominal CT scan revealed involvement of the ovaries and uterus, prompting hysterectomy with bilateral oophorectomy. After discharge, she received chemoendocrine therapy. However, she subsequently died due to peritoneal carcinomatosis.
