Novel Asymmetric Y Design of Fascial Sling for Restoration of Oral Competence and Adequate Mouth Opening in Oral Commissure Defects Post-Malignancy Resection

Reconstruction of through-and-through defects of cheek and commissure resulting from cancer resection are challenging. The specialized function of oral competence that the oral commissure and lip play is difficult to replicate with flap only reconstruction. Static slings play an important role in improving the functional and aesthetic outcome. The asymmetric "y" fascial sling helps in achieving the goals of oral competence along with adequate mouth opening. A total of 10 patients were operated by this technique. The results were satisfactory in terms of functional and aesthetic outcome postsurgery and were maintained 6 months postradiation.

Dermal Template for Superficial Defects Related to Intra Oral Malignancy

Flaps are the workhorse reconstructive options for management of defects for oral malignancy. Superficial defects are traditionally managed with skin grafting or healing by secondary intention, each of which have its own problems. We would like to share our experience of use of dermal template for superficial intra oral defects related to oral malignancy. Patients with cancerous and pre-cancerous lesions which resulted in defects involving mucosa and superficial muscles were included in the study. All the patients were managed with Matriderm 2 mm dermal template without the use of skin graft/ flap. 7 patients in the period of 6 months with superficial defects were managed with Matriderm alone. Two patients had lesions on the tongue while five had it on Buccal mucosa. None of these patients had post operative pain, contracture or trismus. Speech and swallowing at 6 month average follow up is normal. Dermal Substitutes are effective method of management of superficial intra oral defects with no donor area morbidity.

Non-COVID-19 Cutaneous Mucormycosis from a Plastic Surgical Perspective

Background  Cutaneous mucormycosis is a rare and fulminant infection associated with high mortality. Plastic surgeons come across this infection in the settings of road traffic accidents, surgical site infections, and as a secondary infection with underlying bacterial soft tissue infections. Due to this infection's rarity and aggressive course, it is essential to initiate prompt multidisciplinary management at the first presentation. With this study, we aim to present a protocol for managing the condition. Methods  This is a retrospective observational study of patients with cutaneous mucormycosis managed at a tertiary care hospital from January 1, 2016 to November 30, 2022 excluding patients with mucormycosis who tested positive for coronavirus disease 2019. Results  Of 24 patients, 22 were males, and most were in the age group of 41 to 60 years. Sixteen patients survived and five out of eight deceased had comorbidities, six presented primarily without prior debridement, and six had trunk involvement. Conclusion  A high index of clinical suspicion is necessary for early diagnosis and management of patients with invasive cutaneous mucormycosis. A multidisciplinary approach with appropriate medical and surgical management can improve outcomes in cases that otherwise carry a high mortality rate.

Successful Outcome of Post Liposuction Extensive Necrotizing Soft Tissue Infection of Abdomen and Concomitant Jejunal Perforation-A Case Report

Introduction Liposuction is one of the common cosmetic surgery procedures performed. Although rare, the complications associated with it are necrotizing soft tissue infection and bowel perforation. We would like to share our experience of such a complication that was managed successfully. Case Report We were referred a 65-year-old male patient with signs and symptoms of intestinal obstruction who had undergone liposuction of abdomen 1 week before and now had discoloration of the abdominal skin. The discoloration was present from just below the costal margin and was extending up to bilateral inguinal regions. Laterally the discoloration extended up to the mid axillary line on both sides. Imaging studies showed dilated small bowel. During laparotomy, he underwent debridement of all discolored skin and repair of the single jejunal perforation. Postoperatively patient was first managed on intravenous fluids, nasogastric aspiration and total parenteral nutrition for 10 days. The wound was managed with silver dressings that led to healthy granulations. The patient was at high risk for anesthesia for skin grafting; hence, he was managed with allograft for 10 days. The patient then underwent skin grafting once he was fit. The graft took up well and he resumed regular activities. Conclusion This is unique as the patient had extensive necrotizing soft tissue infection of the abdominal skin after liposuction along with intestinal perforation and obstruction that was managed successfully due to aggressive surgical intervention, allograft, and good supportive care both in the intensive care unit and in ward.

Replantation in scapulothoracic avulsion amputation of the right upper limb in a 3-year-old child- A preliminary report

Replantations for major amputations of upper extremity have been widely performed. We report a unique case of successful replantation of scapulothoracic avulsion amputation in a child. In this manuscript, we discuss the various challenges faced during the procedure and chances of neural recovery.

Minimising the donor area morbidity of radial forearm phalloplasty using prefabricated thigh flap: A new technique

Phalloplasty is indicated in various conditions of penile loss or absence. There are numerous techniques for phalloplasty including the pedicle and free flaps with the ultimate goal of micturition in standing position, attaining adequate size, aesthesis and sensations for sexual intercourse. Radial forearm phalloplasty is the gold standard flap to achieve above results but gives a very bad scar on the forearm. We present a technique of using prefabricated thigh flap to reduce the morbidity of donor area. The descending branch of lateral circumflex femoral pedicle was placed in a subcutaneous plane over tissue expander. After attaining an adequate size of flap with tissue expansion, it was delayed 3 weeks before phalloplasty. Prefabricated flap was thin and of large size replicating the radial forearm flap used for phalloplasty. Whole forearm defect was covered with the thigh flap, and the thigh could be closed primarily. This new technique of using prefabricated thigh flap has significantly reduced the donor site morbidity both aesthetically and functionally without the use of skin grafting in the whole procedure.

A case series of flow-through free anterolateral thigh flap to augment the vascularity of ischaemic limbs with soft tissue defect

Introduction:

In a world of fast moving vehicles, heavy machinery and industries crush injury to limbs with vascular compromise and soft tissue defect is common. The traditional treatment is a 2 step one dealing with vascular repair and soft tissue cover separately, in the same operation. We report a series of single step vascular repair and soft tissue cover with flow through anterolateral thigh flap (ALT) flap for limb salvage.

Materials and Methods:

Ten patients with soft tissue defect and vascular injury were included in this study. A two team approach was used to minimise operative time, team one prepared the vessels and team 2 harvested the flap.

Observations and Results:

Of the ten patients operated (8 males), eight flaps were done for upper limb and two for lower limb salvage. Six anastomosis were done with ulnar vessels, two with radial and two with posterior tibial vessels. Nine extremities could be salvaged while one patient developed progressive thrombosis leading to amputation.

Conclusion:

The ALT flow-through flap is a versatile single step procedure that can be used to salvage an ischemic limb with soft tissue loss avoiding the need for interpositional vein graft.

Pedicle streaking: A novel and simple aid in pedicle positioning in free tissue transfer

Introduction:

The pedicle positioning in free tissue transfer is critical to its success. Long thin pedicles are especially prone to this complication where even a slight twist in the perforator can result in flap loss. Pedicles passing through the long tunnels are similarly at risk. Streaking the pedicle with methylene blue is a simple and safe method which increases the safety of free tissue transfer.

Materials and Methods:

Once the flap is islanded on the pedicle and the vascularity of the flap is confirmed, the pedicle is streaked with methylene blue dye at a distance of 6-7 mm. The streaking starts from the origin of the vessels and continued distally on to the under surface of flap to mark the complete course of the pedicle in alignment. The presence of streaking in some parts and not in rest indicates twist in the pedicle.

Observation and Results:

Four hundred and sixty five free flaps have been done at our centre in the last 5 years. The overall success rate of free flaps is 95.3% (22 free flap failures). There has not been a single case of pedicle twist leading to flap congestion and failure.

Conclusion:

This simple and novel method is very reliable for pedicle positioning avoiding any twist necessary for successful free tissue transfer.

A simple and rapid method of repeated tie over dressing

Tie overdressing is commonly used to secure the graft against the raw surface and prevent loss due to of hematoma or seroma. A conventional tie over dressing with silk sutures, is a useful method of securing the graft to raw area. Refixation is difficult when repeated tie over dressings are needed. We assessed a low cost repeated tie over dressing method using sterile sample collection containers and silk suture threads in eight patients. After the graft is applied on the bed, tie-over stitches are taken, and paraffin gauze is applied over with adequate padding; the tie over sutures are passed through the container and the lid is tightened over it to complete the dressing. The lid can be unscrewed easily at any time to inspect the graft and can be easily reapplied in the outpatient department. The skin graft take in all the patients was complete without any seroma or hematoma. A novel and low-cost tie over dressing that enables simple fixation of the dressing, to maintain proper position of grafts that require repeated fixation is reported here.

Body contouring surgery in a massive weight loss patient: An overview

The number of patients with history of extreme overweight and massive weight loss (MWL) has risen significantly. Majority of patients are left with loose, ptotic skin envelopes, and oddly shaped protuberances, subsequent to weight loss. Redundant skin and fat can be seen anywhere on the body following MWL. This group of population presents many unique problems and challenges. Body contouring surgery after MWL is a new and exciting field in plastic surgery that is still evolving. Conventional approaches do not adequately cater to the needs of these patients. Complete history, detailed physical examination, clinical photographs and lab investigations help to plan the most appropriate procedure for the individual patient. Proper counseling and comprehensive informed consent for each procedure are mandatory. The meticulous and precise markings based on the procedure selected are the cornerstones to achieve the successful outcome. Lower body contouring should be performed first followed six months later by breast, lateral chest and arm procedures. Thighplasty is usually undertaken at the end. Body contouring operations are staged at few months' intervals and often result in long scars. Staging is important as each procedure can have positive impact on adjacent areas of the body. Secondary procedures are often required. However, proper planning should lead to fewer complications and improved aesthetic outcome and patient satisfaction.

Primary cutaneous mucormycosis in a premature neonate and its management by tumescent skin grafting

Primary cutaneous mucormycosis is a rare and often fatal disease of infants and neonates. This is a case report of successful management of potentially fatal cutaneous fungal sepsis and use of tumescent technique to harvest a large skin graft with minimal blood loss in a premature neonate.

Omentum autotransplantation in thromboangiitis obliterans: report of three cases

Thromboangiitis obliterans (TAO), also known as Buerger's disease, is an important cause in India of chronic arterial occlusion of the limbs. The current modalities of therapy do not provide adequate relief to a large number of these patients. An omentum autotransplantation to the lower limbs was performed in three patients as a limb salvage procedure. The initial results with up to a year of follow-up are so far encouraging.

Immunogenetic analysis of Buerger's disease in India

In order to understand the role of HLA linked factors in determining susceptibility to Buerger's disease, we have studied 21 unrelated Asian Indian patients belonging to the North Indian states of Punjab, Haryana, Uttar Pradesh and Delhi, representing mainly a lower socioeconomic background. The data was compared with healthy controls belonging to the same ethnic group. The study revealed an over representation of HLA-B40 (60+61) (chi2=6.12; P<0.02) and DR2 (chi2=10.2; P<0.002). Amongst the patients no particular association or linkage disequilibrium with any of the five alleles of the MIC-A gene could be derived in the small sample size studied.

Free-flap urethroplasty for a complex, long-segment stricture of the bulbomembranous urethra

Long strictures of the bulbomembranous urethra are a challenge of modern urology, with no absolutely reliable technique for a favorable outcome. The authors describe a technique of urethroplasty using the radial forearm free flap, in a patient suffering from posttraumatic stricture, with excellent results.

The quality of life in successful live-related renal allograft recipients in India

BACKGROUND

The high cost of maintenance of haemodialysis makes most patients in India and elsewhere opt for a renal transplant. The degree of rehabilitation can best be assessed by evaluating the quality of life in successful recipients.

METHODS

We studied vocational rehabilitation, social relations, sexual and married life, psychological status and life satisfaction in 51 successful live-related renal allograft recipients using Schwab's depressive scale, Bigot's life satisfaction index and the Kamofsky physical scale.

RESULTS

Eight-four per cent of our patients had returned to their original jobs. Ninety-eight per cent of patients had a Kamofsky scale of 90-100 and 81% were leading a normal married life. Ninety-four per cent of them led an active social life.

CONCLUSION

Successful live-related renal transplantation is associated with a good quality of life and should be the treatment of choice for patients with end-stage renal disease.

Evaluation of lymphatic drainage in free flaps by lymphoscintigraphy: a preliminary study

Lymphatic drainage from free flaps was studied by lymphoscintigraphy in 14 patients in whom free vascularised flaps were used to cover defects caused by trauma or tumour ablation. Lymphoscintigrams were done after intradermal injection of Technetium-99m-Dextran in the flap and in the corresponding contralateral normal area. The retention of radioactivity at the injection sites after 1 h was computed and expressed as percentages of baseline activity at the time of injection. 25 studies were done in 14 patients at intervals varying from 9 days to 6 years postoperatively. In all cases, radioactivity was detected beyond the flaps in the lymphatic channels and draining lymph nodes. There was no significant difference (P = 0.27) between the retention of activity in the flaps (mean 88.68%; s.e.m. 1.25) and that in the corresponding contralateral control area (mean 86.88%; s.e.m. 1.35). This study shows that lymphatic drainage in a free flap is established early after surgery.

Multimodality management of a case of primary osteogenic sarcoma of the zygoma

Craniofacial osteogenic sarcomas are rare primary malignant bone tumors and very few cases involving zygomatic bone were reported in literature. We present our experience of multimodality management of a case of primary osteogenic sarcoma of zygoma. Wide radical excision of the tumor including the parotid gland was done followed by three cycles of adjuvant chemotherapy and fifty Gy of external radiotherapy. The patient is disease-free at two years follow-up. Till 1970s, craniofacial osteogenic sarcomas were managed mainly by radical surgery with a high local failure rate. With the advances made in the field of radiotherapy and chemotherapy, multimodality therapy is playing a major role in the treatment of these aggressive tumors with better overall and disease-free survival.

Anterior encephaloceles: a report of 30 cases

Thirty cases of anterior encephalocele treated in our centre over an 18-year period (from 1973 to 1990) are presented. At the time of surgery over 60% of the patients were under the age of 2 years, and 40% were aged under 1 year. Only one child was over 10 years of age. Twenty-six patients had the fronto-ethmoidal type of defect, while two each had frontonasal- and naso-orbital-type lesions. Twenty-five children had varying degrees of hypertelorism. Four had an enlarged head and four microcephaly. In 26 patients one-stage repair of the encephalocele and reconstruction of the orbits was undertaken. A ventriculoperitoneal shunt was performed prior to definitive surgery in three patients with gross hydrocephalus. There was no postoperative mortality. Six patients had postoperative CSF rhinorrhoea, three of them requiring a lumboperitoneal shunt. This study highlights the role of one-stage repair of this defect.

A simple technique for the excision of vascular malformations of the scalp

A simple technique for the excision of vascular malformations of the scalp is described herein. Surgical excision is easily accomplished by placing hemostatic sutures all around the lesion outside the line of excision, whereby minimal blood loss is achieved. The resulting defect can be covered by a split skin graft or flap.

Carcinoma of buccal mucosa: incidence of regional lymph node involvement

Histopathological findings in 57 surgical specimens of T3 and T4 buccal mucosa cancers are reviewed. The incidence of the well-differentiated tumours (including verrucous carcinoma) was 61%. A moderate degree of lymphocytic infiltration of the tumour was present in 37% of patients. Histologically proven cervical lymph node deposits were present in only 16% of the patients. Amongst the group of patients with clinically enlarged lymph nodes, metastatic disease was histologically demonstrated in 17.5% at level I and 14% at level II of neck nodes. Amongst group of patients with no palpable nodes in the neck, metastatic disease was histologically demonstrated in 11.7% at level I and 9% at level II of neck nodes. These findings contra-indicate an elective neck dissection and indicate the need to confirm histologically the presence of lymph node deposits doing a radical neck dissection in patients with buccal mucosa cancer. This well-differentiated tumour has a much lower tendency to metastasize than cancers in other sites of the oral cavity.

An experimental study on the effect of nifedipine on ischaemic skin flap survival in rats

Vasodilators have been employed previously in an attempt to improve survival of ischaemic rat skin flaps. The effect of nifedipine, a calcium channel blocker, on skin flap survival was studied using a standard experimental rat model. The control group had a mean flap necrosis of 37.009%. Rats treated by nifedipine starting 1 day preoperatively and continued for 1 week postoperatively had a mean necrosis of 10.0953%. Rats treated by nifedipine started postoperatively and continued for 1 week had a mean flap necrosis of 12.289%. Treated groups had significantly lower flap necrosis in comparison to untreated controls. There was no significant difference in flap necrosis between the two treated groups. This study shows that nifedipine improves survival in standard ischaemic rat skin flaps.

Results of management of facial palsy with microvascular free-muscle transfer

This paper reports our experience in facial reanimation using free innervated muscle transfer in 69 patients with long-term facial palsy. The majority of patients were treated in two stages with cross-facial nerve graft as the first stage and microvascular muscle transfer at the second stage. The gracilis muscle was used in 62 patients. A system of grading results has been utilized in the long-term evaluation. The overall final result was excellent or good in 51 percent of 47 patients who were available for follow-up. Although the results are not completely satisfactory, they justify the use of this approach to a difficult clinical problem. The results are improving as technical modifications to the procedure have evolved. The gracilis muscle is a reliable free transfer with internal anatomy conductive to use for reanimation of the paralyzed face. This type of transfer, in our experience, has proved superior to nonmicrosurgical methods for treatment of complete and severe incomplete facial palsy. The seventh cranial nerve is used in the innervation of the transferred muscle, the ipsilateral being preferable if available. The authors believe that use of the same cranial nerve is superior to methods that involve other cranial nerves, where spontaneity is often not achieved.

Microsurgical transfer of the greater omentum in the treatment of canine obstructive lymphoedema

In 13 dogs, experimental obstructive lymphoedema of the lower limb was created by combined radiotherapy and radical groin dissection. Six months later, when the degree of lymphoedema was stable, the lymphatic obstruction was bridged by microvascular insertion of a free omental graft. Six months after grafting, circumferential measurements indicated a statistically significant 38% reduction in the magnitude of lymphoedema. Biopsies showed the omental grafts were alive but contained much fibrous tissue. Lymphatic vessels were identified in 10 of 11 biopsies but connections between these lymphatics and lymphatics proximal to the graft could not be demonstrated by either lymphangiography or dye-injection techniques. The findings indicate that experimental obstructive lymphoedema in the dog can be reduced significantly by insertion of a vascularised omental graft. However, it could not be established that improvement was due to union of graft lymphatics with those of the lymphoedematous limb, although this union may have consisted of lymphatics too small to be demonstrated.

Long-term results after microlymphaticovenous anastomoses for the treatment of obstructive lymphedema

Over the last 14 years, 134 patients with obstructive lymphedema have been treated with microlymphaticovenous anastomoses. Ninety patients were available for long-term follow-up study. Of these, 52 patients were treated by microlymphatic surgery only and 38 of them also had segmental or radical reduction surgery, either at the same time or secondarily. Objective assessment was undertaken by volume and circumferential measurements. Initially, lymphangiography was used, but a study demonstrated increased edema immediately following the investigation in one-third of the patients and it was abandoned, both preoperatively and postoperatively. In the microlymphaticovenous anastomoses only group (N = 52), subjective improvement occurred in 38 patients (73 percent). Objectively, volume changes showed a significant improvement in 22 patients (42 percent), with an average reduction of 44 percent of the excess volume. In the microlymphaticovenous anastomoses and reduction surgery, usually segmental, group (N = 38), subjective improvement occurred in 30 patients (78 percent) and objective improvement occurred in 23 patients (60 percent), with an average reduction of 44 percent of the excess volume. Of those followed up, 67 patients (74 percent) have been able to discontinue the use of conservative measures, with an average follow-up of 4.0 years and average reduction in excess volume of 26 percent. There was a 58 percent reduction in the incidence of cellulitis following surgery. In those patients who were improved, drainage resulted in increased softness of the limbs. Edema of the hand diminished considerably in most patients, although this was difficult to measure. These long-term results indicate that microlymphaticovenous anastomoses have a valuable place in the treatment of obstructive lymphedema and should be the treatment of choice in these patients. Reduction surgery can be used as an adjunct in some of these patients, especially in the posteromedial aspect of the upper arm. Liposuction has been used in failed cases or in patients in whom no lymphatics could be found. Improved results can be expected with earlier operations because patients referred earlier usually have less lymphatic disruption.

The anatomy of the subscapular artery and its effects on flap design in the rabbit

The course of the subscapular artery was studied in 20 rabbits. Its course was constant, giving two branches to the latissimus dorsi muscle after which the vessel sent a branch (S1) that perforated the panniculus carnosus to supply a large territory of skin. In a separate experiment, the contribution of the S1 branch to the viability of the rabbit latissimus dorsi musculocutaneous flap was evaluated. From this experiment it can be concluded that, first, it is possible in a rabbit to elevate a large skin flap based solely on a muscle perforator (S1), which survives completely. Second, in the rabbit latissimus dorsi musculocutaneous flap, S1 is the major blood supply to the skin component. Damage to it severely diminishes skin flap survival, even if the vascular supply to the underlying muscle is completely intact.

Liposuction in the treatment of lymphoedema; a preliminary report

Liposuction was used in the treatment of primary and secondary lymphoedema in 19 patients. Seven patients had no previous surgical treatment and 12 had previously been treated with microlymphaticovenous anastomoses and/or surgical reduction. There was subjective improvement in 11 of the 13 patients available for follow-up. There was objective improvement in 10 of the 11 patients with unilateral lymphoedema, with an average reduction of 23% of the excess volume. Seven of the 13 patients were on conservative treatment prior to liposuction. The average reduction in this group was 20.5%. The average follow-up time was 9.5 months. From this preliminary report it can be concluded that liposuction, either as a primary procedure or as an adjunct, can be a useful procedure in the treatment of both primary and secondary lymphoedema.

Coumarin and 7-hydroxycoumarin treatment of canine obstructive lymphoedema

1. Canine obstructive lymphoedema was created in one hind leg of 30 dogs by irradiation of the groin and surgical removal of surviving lymph glands and lymphatics. The opposite leg served as a control. Once the oedema had stabilized, groups of 10 dogs were treated orally with 12.5 mg day-1 kg-1 for 8 months with either one of the benzopyrones coumarin (2H-1-benzopyran-2-one) and 7-hydroxycoumarin (7-hydroxy-2H-1-benzopyran-2-one), or placebo. 2. The two benzopyrones significantly (P less than 0.01) but gradually reduced the oedema by 20-30% over 8 months, as judged by circumferential measurements of the oedematous and control limbs. There was no change with the placebo. 3. In the oedematous fluids (lymph and interstitial fluid), benzopyrone treatment reduced the protein content and increased acid and neutral proteinase activity compared with the control limbs, while the levels of the proteinase inhibitor alpha 2-macroglobulin remained unchanged. Furthermore, these active drugs reduced the excess water content, thickness and hydroxyproline content of skin biopsies from oedematous limbs compared with those from control limbs. No changes were observed for the placebo group. 4. These biochemical changes suggest that benzopyrones can reduce the excess proteinaceous fluid in lymphoedema by increasing the levels of proteinase activity relative to the number of proteinase inhibitors. As a secondary event the amount of fibrosis in the skin is also reduced, presumably by an increase in collagenase activity from the mononuclear phagocytes. 5. These results support the hypothesis that benzopyrones activate the production of proteinases by mononuclear phagocytes.(ABSTRACT TRUNCATED AT 250 WORDS)

Effect of phosphoenolpyruvate and adenosine triphosphate on rabbit skeletal muscle after ischaemia: preliminary biochemical study

The present study examined the effect of phosphoenolpyruvate (PEP) and adenosine triphosphate (ATP) on rabbit skeletal muscle flap survival after warm ischaemia. Two muscle flap models, rectus femoris pedicle flap and latissimus dorsi free flap, were subjected to a total ischaemia of 4 hours at 37 degrees C and 20 degrees C, respectively. Immediately prior to revascularisation, the muscles were infused with either Hanks' balanced salt solution (BSS) or Hanks' BSS containing 200 mumol PEP and 6.6 mumol ATP. Quantification of muscle damage was determined by measuring the plasma levels of creatinine kinase (CK), lactate dehydrogenase (LDH), lactate, potassium, and phosphate at 0, 2, 24, and 96 hours after revascularisation. Infusion of PEP/ATP compared with Hanks' BSS alone significantly decreased the efflux of CK in both rectus femoris (P less than 0.025) and latissimus dorsi muscles (P less than 0.05) and of LDH in the rectus femoris muscle (P less than 0.01). No significant changes were observed, however, for the plasma levels of lactate, potassium, and phosphate. From this study it was concluded that PEP and ATP partially protect skeletal muscle from ischaemia and reperfusion injury.
