Bone marrow as a means of venous drainage for a microvascular osteocutaneous flap.

Intraosseous infusion of fluid had been used in traumatology. Here we describe a clinical situation in which bone marrow is first used for drainage of venous blood in a free osteocutaneous flap. Two factors account for the survival of the large osteocutaneous flap in which venous anastomosis was impossible. (1) In the design of the arterial circuit and the major route of venous drainage, there were two ends of the peroneal artery of the osteocutaneous flap. Both its upper and lower ends were anastomosed to the anterior tibial artery of the recipient site to constitute an uninterrupted arterial circulation. This prevented stagnation of arterial flow and thrombosis of the arterial anastomosis. (2) The major route of venous drainage was through bone marrow. The initial congestion was finally overcome by the development of neovascularization. Bone scan showed good survival of bone with increased uptake of radioactivity. At 3 years follow-up, roentgenogram showed bone union, and the patient had no trouble walking. The continuity of the anterior tibial artery, which had been interrupted by trauma, was restored by this flap.

Early reconstruction of pharynx and esophagus following corrosive injury with radial forearm flap in preparation for colon interposition.

In 24 patients, corrosive injuries involving the floor of the mouth, the pharynx, and the esophagus were repaired in two stages using a combined free forearm flap and colon for functional restoration of the alimentary tract. The results were satisfactory. Morbidity was decreased, complications were minimal, and there were no failures. In the first stage, early reconstruction with a forearm flap for the oral floor, the pharynx, and the cervical esophagus can be done safely 3 months after the original injury when the acute inflammation of the tissue has disappeared. The forearm flap is thin and pliable, and has a good blood supply for primary healing without failure or stricture. Dysphagia is eliminated because food passes down by gravity. There is no constriction or hyperperistalsis of the colon, both of which are occasionally seen with the traditional colon interposition. In the second stage, the traditional method is used to finish the reconstruction of the remainder of the esophagus.

Clinical comparison of commercially available Biobrane preparations.

This prospective clinical comparison of the three commercially available Biobrane preparations indicated that: (1) All three products of Biobrane are excellent skin substitutes. (2) Regular Biobrane has satisfactory wound adherence, however, its non-porous structure allows limited wound drainage. Because of this, it has the highest incidence of haematoma and fluid accumulation (13.3 per cent) and delayed epithelialization (18.8 per cent) of the three products. (3) Thin Porous Biobrane has poor adherence which limits patient activity and provides poor pain relief. The infection rate of 10 per cent was the highest of the three products. (4) Regular Porous Biobrane demonstrated superiority to the other two Biobrane products in this study. It provided good wound adherence while maintaining wound drainage because of its porous structure. The incidence of blood or fluid accumulation (7.1 per cent) was the lowest in the three products. (5) Most of the complications such as infection, delayed epithelialization, pain and activity impairment were related to fluid or blood accumulation. Adherence was found to be more important and reliable than pore structure. Operative haemostasis thus should be emphasized when using porous Biobrane, as with all skin substitutes.

Bilateral cleft lip reconstruction.

Over a period of 8 years 140 bilateral cleft lips were operated using a muscle-repositioning banked fork-flap cheiloplasty. The use of buccal mucosal flaps in the intercartilaginous incision is helpful to decrease scarring and contracture by facilitating alar cartilage repositioning and wound closure without tension. Adding mucosa from the inferior turbinate makes complete wound closure relatively easy without tension. A lateral lip orbicularis muscle flap with white skin roll and vermilion is recommended for reconstruction of the Cupid's bow. Muscle continuity by freeing the muscle in one sheet and repositioning in front of the premaxilla with creation of a buccal alveolar sulcus is stressed to prevent the necessity of reentering the lip in a second procedure. The elongation of the columella is done at 1 to 6 years of age by advancing nasal floor tissue onto the columella and repositioning the alar cartilages superiorly and medially. When nasal floor tissue is inadequate, columellar lengthening is done by the use of a composite free ear graft.

Reconstruction of vermilion in unilateral and bilateral cleft lips.

The white skin roll is a useful term to describe the cutaneo-vermilion border of the lip. The muco-vermilion border line parallels the white skin roll and is described as the red line. The lip vermilion should be constructed so that these lines are parallel and widest at the base of the philtral column. It is suggested that the triangular lateral lip vermilion flap be used in unilateral cleft lips. In bilateral cleft lips, a white skin roll vermilion-mucosal muscle flap is used for reconstruction of vermilion.

Early adipofascial flap coverage of deep electrical burn wounds of upper extremities.

The adipofascial flap is a useful method for treating deep electrical burn wounds requiring early definitive wound closure to preserve vital structures and function. In the past 2 years, 14 deep electrical burns of the upper extremities involving exposure of tendon, nerve, bone, or blood vessels requiring immediate vessel reconstruction were covered with an adipofascial flap. The latter was a local random turnover flap of the fascia and its overlying subcutaneous fat. All flaps were successfully elevated and applied to severe wounds in order to preserve underlying structures. There were no serious complications. Tendon gliding under the flap was found to be excellent during second reconstructive surgical procedures. The reconstructed limbs had satisfactory preservation of function.

Duplication of stomatodeal structures: report of three cases with literature review and suggestion for classification.

Three cases of duplications of stomatodeal structures are reported. One had an accessory mouth that could move simultaneously with his mouth at sternal notch. Another had a teeth-bearing bony mass at left maxilla with excessive upper lip and a false pouch. The third had an excessive upper lip, upper jaw with teeth, and hard and soft palate. The literature is reviewed, and a classification is suggested: type I, a duplicated mouth; type II, duplication of maxilla-upper lip or mandible-lower lip complex; and type III, centrally located, poorly developed lip-jaw duplication.

Treatment of craniomaxillofacial fibrous dysplasia: how early and how extensive?

Twenty-eight craniomaxillofacial fibrous dysplasia patients were treated as early as the symptoms occurred. The principles of surgical treatment were based on the zones of involvement: total excision of dysplastic bone of fronto-orbital, zygoma, and upper maxillary origin (zone 1) and bone reconstruction primarily; conservative excision on hair-bearing skull (zone 2), central cranial base (zone 3), and tooth-bearing bones (zone 4); and optic canal decompression on patients with orbital dysplasia and decreasing visual acuity. Patients were followed for 1 to 11 years (average 5.3 years). No recurrence or invasion of the fibrous dysplasia into the grafted bone was seen. One patient had orthognathic maxillary osteotomy on the reconstructed maxilla 6 years after initial reconstruction. Five of 19 patients with alveolar dysplasia had a recurrence and were reshaped. One patient had mandibular sagittal osteotomies to set back the prognathic, fibrous dysplasic mandible after three attempts at conservative shaving. Another patient with mandibular fibrous dysplasia had recurrence with pain and a hemimandibulectomy with successful immediate free vascularized iliac bone graft reconstruction.

Complications of Oriental blepharoplasty.

The complications of Oriental blepharoplasty are described according to their clinical appearance and anatomic findings at the time of surgery. The surgical correction of these complications is presented. A total of 42 patients with complications following blepharoplasty were treated. The types of deformities were categorized from their external appearance as asymmetry, retraction and ectropion, blepharoptosis, supratarsal depression, fading of the lid fold, and hemorrhage. The causes of each type of complication are identified according to the intraoperative findings, and the correlation between preoperative and intraoperative findings is explained. Correction of these complications follows identified guidelines, and the results were good to satisfactory.

Posterior tibial artery flap for reconstruction of the esophagus.

Three patients presented who needed reconstruction of the entire esophagus. Because the stomach and colon were not available in these patients, a posterior tibial artery flap was employed for reconstruction. In the first stage, the long and wide skin flap was elaborated into a skin tube to create the major portion of esophagus in the subcutaneous tunnel. In the second stage, the lower end of the skin tube was joined to the jejunum in Roux-en-Y fashion. This method resulted in smooth passage of food and early rehabilitation for these patients. However, this procedure has the disadvantage of a scar over the leg. In addition, this procedure has the following limitations: (1) a well-vascularized leg is necessary, and (2) a hairless leg is necessary. Although this would not be a procedure of first choice, it remains a worthwhile backup procedure in esophageal reconstruction.

One rectus abdominis muscle for two separated soft-tissue reconstructions.

One rectus abdominis muscle flap, when based on superior and inferior pedicles, can be transferred simultaneously as two free-muscle flaps in two different configurations during the same operation. The two free flaps based on either pedicle are safe, reliable, and extremely well vascularized. Excellent functional and cosmetic results have been achieved in five patients with minimal donor-site morbidity. It has been our flap of choice for reconstructing the moderate- to large-sized defects at two separate sites of the upper and lower extremities.

Coverage of multiple extensive pressure sores with a single filleted lower leg myocutaneous free flap.

A large free flap from an amputated lower extremity based on popliteal vessels was used for coverage of three extensive decubitus ulcers in a single operative procedure. The procedure was easy, reliable, and actually time- and cost-saving. It provided a quick solution and early rehabilitation for a difficult problem.

Salvage replantation of two fingers from a nonreplantable midpalm.

To achieve better functional results following mutilating multidigital trauma, every effort should be made to maximize the ultimate function of the hand, and the plan of replantation should be guided accordingly. All usable parts should be salvaged from the amputated nonreplantable areas. A patient is reported in whom two fingers taken from the nonreplantable midpalm were used to reconstruct the thumb and ring fingers, ultimately improving the overall quality of the patient's life.

Median facial dysplasia in unilateral and bilateral cleft lip and palate: a subgroup of median cerebrofacial malformations.

The median facial dysplasia group of patients is a unique, distinct, definable group characterized by mid-line facial deficiencies in the presence of a unilateral or bilateral cleft lip with or without cleft palate and without clinically detectable anomalies of the brain. This group of patients comprised 2 percent of new cleft lip and palate patients. The midline facial deficiencies in median facial dysplasia are characterized by a poorly defined Cupid's bow, absence of the labial frenulum and anterior nasal spine, deficient columella, and poorly developed septal cartilage and premaxilla. One of the central incisors may be absent or rudimentary. There are no definable gross abnormalities of the brain. The results of intelligence tests of median facial dysplasia patients have a normal distribution and are not significantly different from those of a noncleft normal population. Unoperated and operated median facial dysplasia patients all have typical midfacial growth disturbances below the norm for their ages. The classification of median facial dysplasia patients as well as other median cerebrofacial anomalies, the embryologic basis of these deformities, and the clinical results of their treatment are helpful in understanding some of the problems related to the treatment of the cleft lip and palate patient. Median facial dysplasia patients demonstrate an inherent potential for poor midfacial growth. Deficiencies of soft tissue such as a lack of the Cupid's bow make it difficult to reconstruct the lip and nose satisfactorily.

Cross-chest C7 nerve grafting followed by free muscle transplantations for the treatment of total avulsed brachial plexus injuries: a preliminary report.

The number of donor nerves available for nerve transfer in the reconstruction of total root avulsion injuries of the brachial plexus is always insufficient. Use of the contralateral normal C7 cervical nerve as a donor nerve is a new approach to obtain more nerve fibers but also is a controversial procedure. Fifteen patients with total root avulsion of the brachial plexus received cross-chest C7 nerve grafting as the first stage of reconstruction. Eight of these patients, after an interval of 11 to 20 months, had free muscle transplantations (one to three muscles transferred per individual) to the affected limb. A long period of rehabilitation (at least 2 years) is required. The donor limbs of the 15 patients showed negligible deficits of motor and sensory function. Although independent movement of the transferred muscles from the contralateral limb has not been achieved, useful function of the reconstructed limb is possible. The preliminary results are encouraging.

Reconstruction of the entire esophagus with "chain flaps" in a patient with severe corrosive injury.

A method of reconstructing the entire esophagus by a chain of free forearm flaps connecting pharynx to jejunum is presented. This was indicated because all other means of reconstruction were not possible. It solved a difficult problem with good result, and the patient was satisfied.

Facial midline and symmetry: modified face bow.

A facial "cone" can be drawn inside the head. The apex of the cone is the midpoint of the line that connects both ear canals, point C, and the face is the base. A modified face bow is designed with holes through which a Steinmann pin is passed, meeting at the apex of the facial cone. After the ear bolts are symmetrically fixed, the Steinmann pin through the central hole follows the midline of the face as the bow rotates from the forehead to the chin. The right and left facial bony protrusions can be evaluated by two Steinmann pins projecting through the corresponding holes on the face bow. This device is utilized to determine the facial midline and facial symmetry during surgery. It also can be used as a tool for anthropologic studies.

Patch esophagoplasty with free forearm flap for focal stricture of the pharyngoesophageal junction and the cervical esophagus.

Focal stricture of the cervical esophagus can be caused by corrosive injury or irradiation or following esophageal reconstruction. For severe stricture that cannot be relieved by bougie dilatation, surgical correction should be done. Among the operations performed, the myocutaneous flap is considered the first choice. Patch esophagoplasty with a free flap is indicated in the following situations: (1) when the patient is a young woman, (2) when the patient is obese, and (3) following irradiation that renders myocutaneous flaps unreliable. For correction of focal stricture of the cervical esophagus, six patients underwent esophagoplasty with a patch of free forearm flap. In comparison with other methods, this approach is associated with less morbidity and a better aesthetic result. The patients started oral intake at 1 month. Only one patient had minor leakage, and this healed after conservative treatment. The skin patch inserted in the esophageal wall caused no problem in motility, and the patients could eat smoothly after surgery.

Second toe wrap-around flap.

The microsurgical second toe wrap-around technique is an ideal treatment option for reconstruction of the distal half of the finger with circumferential loss of skin and nail associated with an uninjured proximal interphalangeal joint and an intact insertion of the flexor digitorum superficialis tendon. Follow-up of 13 flaps in 10 patients from 1986 to 1989 demonstrates rapid and adequate functional recovery as well as satisfactory aesthetic appearance in all patients.

Simultaneous bilateral forearm revascularization.

A successful simultaneous bilateral forearm revascularization was performed on a 17-year-old boy. Functional recovery of both forearms was evaluated 42 months after injury. The patient can use both hands for the activities of daily living. So far, he has been employed and has no significant psychological problems. Temporary intraluminal silicone shunts are extremely helpful for reducing ischemic damage to the injured limb. The sufficient skeletal shortening of the upper limb replantation is crucially important. The wounds must be managed by aggressive and repeated debridement. Accurate primary nerve repair is essential, and the early postoperative rehabilitation is also important to achieve a satisfactory functional return. The functional replanted or revascularized upper extremity is superior to an amputation or prosthesis, especially in the cases of bilateral upper extremity amputation or devascularization.
