Superficial angiomyxoma of the posterior neck

황영중,Hong Won Lee,Il Seok Lee,정성균,Hye Kyung Lee 대한두개안면성형외과학회 2021 Archives of Craniofacial Surgery Vol.22 No.1

Superficial angiomyxoma (SA) is a rare, benign, cutaneous soft tissue tumor. It is composed of myxoid matrix and blood vessels. Herein, we report a case of a solitary SA on the posterior neck of a 6-year-old boy. An analysis of the biopsied specimen showed a prominent myxoid stroma with thin-walled, branching blood vessels, revealing the presence of an SA. SA especially that originating in the posterior neck, is rarely seen and should be considered as a differential diagnosis for a solitary mass in the posterior neck.

In the repaired cleft lips, the residual deformities and disfigurements make the patients hesitant to participate in society. One reason is the scars over the whole length of the upper lip, especially in the occult or mild degree partial cleft lip. The Tinnison triangular flap or Millard rotation-advancement flap methods, have been too radical to put into pratice. Frequently we meet patients and parents who complain about the scars on the repaired cleft lip in spite of the fine and good scars on the upper lip, particularly in the occult or mild degree partial cleft lip. These authors propose a new technique which leaves only minimal, short scars on the upper lip for the occult or mild degree partial cleft lip. I performed this technique eight patients. The resutls are satisfactory. We now briefly introduce this techniqus. The incision was made just on the malaligned mucocutaneous junction or cleft margin, and then extended to the upper labial sulcus after the same design and tatooing with gentian violet by the Millard rotation-advancement method. Through this in cision the orbicularis oris muscles were undermined from the anterior nasal spine to the pyriform aperture of the alar base, but the skin of the upper lip was not incised, and then the C-flap on the non cleft side and B-flap on the cleft side beneath the skin were made on the orbicularis oris muscles only.

Epinephrine is often used with local anesthtics to decrease absorption of anesthetics and to reduce bleeding within the operative field. Despite of the wide use of epinephrine, the effects of this agent on skin graft is not known clearly. In the present study, 0.5% lidocaine with or without 1:100,000 epinephrine was infiltrated before harvesting of full thickness skin grafts on dorsum of New Zealand white rabbits(88 grafts/12rabbits). After weighing harvested full thickness skin grafts by using electric balance, grafts were replaced into original sites after same ischemic times. One day after operation, the weight of grafts in each control and experimental group was measured again and compared with previous data(weight increase was 18.5% in control group and 16.8% in experimental group, p>0.05). On 7 days postoperatively, grafts survival treated with epinephrine showed no difference with control group(80.7% in control group and 72.35 in experimental group, p>0.05) Statistical analysis of weight revealed no significant effect to plasmic circulation of full thickness skin grafts after injecting of epinephrine and that of graft survival showed epinephrine injection did not affect the survival in full thickness skin graft.

D.I.T.I.(Digital infrared thermographic imaging) system is noninvasive, easy to reading, objective and physiologic instrument by measuring and imaging infrared energy emitted from skin surface. It detects surface body heat into a visible display, which is then photographed or videotaped as a permanent record. It graphically depicts temperature gradients over a given body surface area at a given time and has been used to study biologic thermoregulatory abnormalities directly or indirectly influencing skin temperature. As this review specifically addresses clinical problems involving the lower and upper extremities, thermography has been used in numerous sites to evaluate surface thermal changes in variety of conditions. These include spinal nerve root disorders(radiculopathy): nonradicular peripheral nerve impairment due to sensory or autonomic nerve irritation or damage, as in carpal tunnel syndrome ; brachial plexus disorders ; posttraumatic sympathetically maintained pain ; reflex sympathetic dystrophy ; vascular abnormalities including thromboses ; bony and soft tissue injuries and arthritis. Many of these conditions occur in upper extremity loci. Patients with injured extremities were evaluated with the aid of D.I.T.I.. Preoperative and postoperative thermographic imaging were compared regarding to the correlation between the injuries and thermographic image. Close correlation revealed the significance of thermographic imaging in the field of the reconstruction of injured extremities.

Pharyngocutaneous fistula is a dreaded complication of ablative surgery of the aerodigestive tract such as pharynx and larynx. This is a common problem for the surgeon. We present two patients with glottic carcinoma who suffered from pharyngocutaneous fistulae which developed after total laryngectomy and radiation therapy. The fistulae were reconstructed with newly designed radial forearm free flaps. A radial -forearm free flap larger than the defect was elevated and the flap, except the central inner lining area, was deepithelized. Skin around the defect was removed and then deepithelized. The inner lining was made with the central skin paddle. The deepithelized area was placed over the deskinned area around the defect. The final outer covering of skin graft was extended to the surrounding deepithelized areas. We obtained a obliteration of the fistulae and natural neck contour using this method. This new design has the following advantages; large contact area between the flap and the inflammed surrounding tissue, discontinuity between the suture lines of the inner lining and the outer covering, and reinforcement of suture line of outer covering with skin graft. We believe that this is a useful method for reconstructing irradiated pharyngocutaneous fistulae.

Traumatic loss of a finger in part or in which inevitably leads to significant functional deficit and a distortion in body image of the inflicted individual. The available reconstructive option in these circumstances have been toe to finger transfer using microsurgical technique, flap coverage after bone graft, and osteodistraction of the remnant finger. Each method carries advantages and drawbacks inherent in the technique, and generally requires long operative time and hospitalization. Furthermore, the postoperative results after such procedures can be said to be less satisfactory in aesthetic perspectives. Apart from the toe to finger transfer, not much can be sought in terms of functional recovery of the reconstructed part, For a long time finger prosthesis have been used as a replacement of the lost finger part, but it fails to deliver functional strength and tends to be dislodged rather easily. To overcome these shortcomings in the technique, an osseointegrated finger prosthesis has recently been devel-oped. Thumb, index and middle finger in 3 patients were reconstructed with this osseointegrated finger prosthesis. The procedure requires two procedures; the first stage involves placement of a titanium screw in the phalangeal or metacarpal bone proper, followed by fixation of an abutment onto the titanium screw 3 months after the primary operation. The skin surrounding the abutment is thinned out to minimize mobility of the prosthesis at this second stage of operation. After wound stabilization in 2-3 weeks, a custom-made silicone finger prosthesis is made and attached to the implanted abutment using super power magnets. The entire procedure requires 4 months up to the completion, but the procedures can be carried out on the outpatient basis under local anesthesia, not having to interfere with the daily activities of the patient. The aesthetic results with osseoperception have been found to be rewarding, and usual activity like a hand writing and typewriting have been possible. This alternative method could be used for finger reconstruction in cases of usual reconstructive surgery being impossible.

Almost all patients with a cleft lip have varying degree of nasal deformities which sometimes completely dominate their feature and cause some functional problems. No matter how varied the deformities, the major deformities resulted from any method of primary lip repair are not only malrotated but also displaced alar pyriform aperture in involved side. Numerous methods for correction of secondary cleft lip nose deformities have been introduced and the list is growing every year, but there was no standardized procedure with satisfactory results. The author performed alar cartilage reposition with or without onlay graft and septoplasty with augmentation of hypoplastic pyriform aperture in affected side by using autogenous conchal cartilage and we experienced satisfactory results in 43 patients who had secondary unilateral cleft lip nose diformity.

Rectus abdominis muscles are paired anterior paramedian flexors of the vertebral column and they also serve to tense the anterior abdominal wall. Adequate soft tissue coverage is a primary requisite for the reconstruction of the large soft tissue defect of thigh. We have experienced 3 cases of large soft tissue defect of the thigh using inferiorly based rectus abdominis myocutaneous island flap. Advantages of this method are; enough donor tissue, no need for changing position during operation. We think inferiorly based RAMC island flap is one of the most useful flap for the large thigh defect accompanying with or without osteomyelitis.

In human body, lower extremity has some differences from other parts of body such as less blood supply and relatively thin subcutaneous tissue especially in pretibial area, and also soft tissue necrosis and fracture often happened in industrial and traffic accidents. The choice of reconstruction method of injured leg depends on the size and site of defect, and condition of wound as well as contour and function after reconstruction. Donor site morbidity should be considered also. In general, small defect can be covered with local flap or skin graft, but if defect is large in size or combined with bone defect or associated with serious infection like osteomyelitis, free flap is inevitable in most cases and muscle flap which has good provision of blood circulation is well known to be effective in control of infection. The rectus abdominis muscles are paired anterior paramedian flexors of vertebral column, and they serve to tense the anterior abdominal wall. Rectus abdominis muscle flap or myocutaneous flap can be used as a island or free flap and it is now one of the most frequently used flap for reconstruction of leg with many advantages. From May,1990, eleven patients underwent lower extremity reconstruction with rectus abdominis muscle flaps or musculocutaneous flaps for soft tissue defect with serious infection, osteomyelitis, bone defect. The result is good in contour and function of leg as well as control of infection, so we report this paper with review of literatures.
