Islandized mucoperiosteal flaps: A versatile technique for closure of a wide palatal cleft

BACKGROUND:

A variety of surgical methods have been described to repair wide cleft palate; they are all challenging to perform and yield consistently good results. The islandized mucoperiosteal flap, the technique described in the present article, is very versatile because it can close palatal defects of any size without undue tension. Moreover, it provides adequate length and mobility of the soft palate with improved speech and feeding functions without fistula formation.

METHODS:

Between 2005 and 2011, 36 patients with wide cleft palate were operated on using islandized mucoperiosteal flaps. This technique involves dissection of the neurovascular bundle from the mucoperiosteal flaps for approximately 1 cm and dissecting the muscle from the posterior edge of the hard palate with intravelar veloplasty. The flaps subsequently become freely mobile in all directions. It can move medially to close palatal defects of any size without tension. In addition, posterior or backward mobilization lengthens the soft palate and renders it freely mobile.

RESULTS:

All repairs were successful, with no complications and no patients requiring secondary procedures. All patients regained normal feeding function three weeks postoperatively. All patients showed normal nasal resonance of speech except for two (three and five years of age) who experienced abnormal resonance in the form of open nasality that required regular speech therapy for six months. There was significant improvement and no secondary procedures were required for either.

CONCLUSIONS:

A technical modification for closure of wide palatal clefts is introduced. The islandized mucoperiosteal flap, which is a very versatile technique, can close cleft palates of any width without tension, lengthens the soft palate and renders it freely mobile for proper speech functions. Using this technique, good speech and feeding function with no complications were achieved.     

Transperitoneal Transvesical Laparoscopic Repair of Vesicovaginal Fistulae: Experience of a Tertiary Care Centre in Northern India

Objective

To present our experience of treating supratrigonal vesicovaginal fistulae by laparoscopic technique and their long-term follow-up.

Material and Methods

Between January 2008 and June 2012, 28 cases of supratrigonal fistulas were repaired by laparoscopic transperitoneal transvesical technique with interposition flap. The obstetric fistula was present in 18 and gynecologic fistula in 10 patients. Single supratrigonal fistula was present in 26 patients and in 2 patients there were 2 fistulae lying side to side. The vaginal opening was closed as single layer interrupted suture and cystotomy closed as single layer continuous suture by 3-0 polygalactin. The omentum was used as interposition flap in all except 2 cases in whom postero-superior vesical fold of peritoneum was used. The open conversion was required in 2 cases. The urethral catheter was removed in 4 weeks following a micturating cystogram.

Result

The mean fistula size was 1.2 cm (range 0.8-2.5 cm). Open conversion was performed in 2 cases of whom one had excess carbon-dioxide retention and cardiac arrhythmia and in another case the needle of 3-0 polygalactin was avulsed and lost in peritoneal cavity which was recovered following laparotomy. All patients were continent following the catheter removal. The median follow-up is 24 months. None developed any complication related to laparoscopic repair till last follow-up.

Conclusion

Laparoscopic repair of supratrigonal vesicovaginal fistulae is an effective and safe minimally invasive treatment with excellent result.Key Words: Transperitoneal approach, Laparoscopic surgery, Vesicovaginal fistulae     

Microvascular free flap reconstruction for head and neck cancer in a resource-constrained environment in rural India

Introduction:

Reconstruction with free flaps has significantly changed the outcome of patients with head and neck cancer. Microsurgery is still considered a specialised procedure and is not routinely performed in the resource-constrained environment of certain developing parts of India.

Materials and Methods:

This article focuses on the practice environment in a cancer clinic in rural India. Availability of infrastructure, selection of the case, choice of flap, estimation of cost and complications associated with treatment are evaluated and the merits and demerits of such an approach are discussed.

Results:

We performed 22 cases of free flaps in a six-month period (2008-2009). Majority (17) of the patients had oral cancer. Seven were related to the tongue and eight to the buccal mucosa. Radial forearm free flap (RFF: 9) and anterolateral thigh flap (ALT: 9) were the most commonly used flaps. A fibula flap (1) was done for an anterior mandible defect, whereas a jejunum free flap (1) was done for a laryngopharyngectomy defect. There were six complications with two re-explorations but no loss of flaps.

Conclusion:

Reconstruction with microvascular free flaps is feasible in a resource-constrained setup with motivation and careful planning.KEY WORDS: Free flap, head and neck cancer, microvascular surgery, reconstruction, resource constrained, reconstruction of head and neck     

Salpingo-ureteric fistula—A rare complication following laparoscopic surgery for colorectal cancer: A case report and literature review

INTRODUCTION

We report the management and outcome of the case of a 57-year old woman with adenocarcinoma of the rectum. Following neo-adjuvant chemo-radiotherapy and laparoscopic-assisted anterior resection of her tumour she developed a right salpingo-ureteric fistula.

PRESENTATION OF CASE

Three weeks following laparoscopic anterior resection of the tumour she presented with urinary frequency and incontinence. A ureteric stent was inserted and left in-situ for five months but the fistula did not heal. The patient underwent exploration and open repair of the salpingo-ureteric fistula which resolved her symptoms.

DISCUSSION

There have not been many reported cases in the literature of salpingo-ureteric fistulae but after initial trial of management with ureteric stents all eventually required open exploration and repair.

CONCLUSION

we advocate open repair of salpingo-ureteric fistulae as the definitive management following intra-operative injury.     

A novel route for placing free flap pedicle from a palatal defect

One of the better options available to repair a large palatal defect is by employing a free flap. Almost all the times such free flaps are plumbed to facial vessels. The greatest challenge in such cases is the placement of the pedicle from palatal shelf to recipient vessels because there is no direct route available. As majority of large palatal fistulae are encountered in operated cleft palates there is a possibility of routing the pedicle through a cleft in the maxillary arch or via pyriform aperture. When such a possibility doesn’t exist the pedicle is routed behind the maxillary arch. We describe a novel technique of pedicle placement through a maxillary antrostomy, in this case report, where a large palatal fistula in a 16 year old boy was repaired employing a free radial artery forearm flap. The direct route provided by maxillary antrostomy is considered the most expeditious of all possibilities mentioned above.KEY WORDS: Free radial artery forearm flap, large palatal fistula, maxillary antrostomy, palatal fistula repair     

The forked flap repair for hypospadias

Context:

Despite the abundance of techniques for the repair of Hypospadias, its problems still persist and a satisfactory design to correct the penile curvature with the formation of neourethra from the native urethral tissue or genital or extragenital tissues, with minimal postoperative complications has yet to evolve.

Aim:

Persisting with such an endeavor, a new technique for the repair of distal and midpenile hypospadias is described.

Materials and Methods:

The study has been done in 70 cases over the past 11 years. The “Forked-Flap” repair is a single stage method for the repair of such Hypospadias with chordee. It takes advantage of the rich vascular communication at the corona and capitalizes on the established reliability of the meatal based flip–flap. The repair achieves straightening of the curvature of the penis by complete excision of chordee tissue from the ventral surface of the penis beneath the urethral plate. The urethra is reconstructed using the native plate with forked flap extensions and genital tissue relying on the concept of meatal based flaps. Water proofing by dartos tissue and reinforcement by Nesbit''s prepucial tissue transfer completes the one stage procedure.

Statistical Analysis:

An analysis of 70 cases of this single stage technique of repair of penile hypospadias with chordee, operated at 3 to 5 years of age over the past 11 years is presented.

Results and Conclusion:

The Forked Flap gives comparable and replicable results; except for a urethrocutaneous fistula rate of 4% no other complications were observed.KEY WORDS: Chordee, fistula, forked flap, hypospadias, urethral plate     

Options for the nasal repair of non-syndromic unilateral Tessier no. 2 and 3 facial clefts

Background:

Non-syndromic Tessier no. 2 and 3 facial clefts primarily affect the nasal complex. The anatomy of such clefts is such that the ala of the nose has a cleft. Repairing the ala presents some challenges to the surgeon, especially to correct the shape and missing tissue. Various techniques have been considered to repair these cleft defects.

Aim:

We present two surgical options to repair such facial clefts.

Materials and Methods:

A nasal dorsum rotational flap was used to treat patients with Tessier no. 2 clefts. This is a local flap that uses tissue from the dorsal surface of the nose. The advantage of this flap design is that it helps move the displaced ala of a Tessier no. 2 cleft into its normal position. A forehead-eyelid-nasal transposition flap design was used to treat patients with Tessier no. 3 clefts. This flap design includes three prongs that are rotated downward. A forehead flap is rotated into the area above the eyelid, the flap from above the eyelid is rotated to infra-orbital area and the flap from the infraorbital area that includes the free nasal ala of the cleft is rotated into place.

Results and Conclusions:

These two flap designs show good results and can be used to augment the treatment options for repairing Tessier no. 2 and 3 facial clefts.KEY WORDS: Facial clefts, Tessier clefts, Tessier no. 2 cleft, Tessier no. 3 cleft     

A simple method for predicting survival of pedicled skin flaps before completely raising them

Background:

Pedicled skin and fasciocutaneous flaps are commonly used in plastic surgery. Once such a flap is completely raised on its pedicle it becomes defenceless against any possible necrosis.

Aim:

To use a simple method for raising such a flap in a manner that can predict the vascularity better, offering additional protection against necrosis.

Materials and Methods:

A total of 30 skin and fasciocutaneous flaps were raised in 27 patients. They were raised as bipedicle flaps; and the vascularity of the flap was tested by occluding the additional pedicle with a pedicle occlusion clamp. If the vascularity was found to be satisfactory the flap was primarily transferred; if found unsatisfactory it was either delayed or abandoned. The delayed flaps were again tested during transfer.

Results:

Nineteen (63.3%) flaps were primarily transferred, 11 (36.7%) flaps were delayed, and two (6.7%) delayed flaps displayed an unsatisfactory pattern during transfer. Twenty-two (73.3%) flaps fully survived and seven (23.3%) underwent partial thickness necrosis at the tip, which healed without any further surgical intervention, making 29 (96.7%) flaps clinically successful. There was major necrosis of one flap. All the flaps with a scar at the base survived.

Discussion:

The clinical success of 96.7% indicated a high-degree of predictability of flap survival through this method. Also, this method could safely assess the vascularity of flaps during primary transfer, during delayed transfer, and also those with a scar at the base.

Conclusions:

This technique is recommended in all major pedicled skin and fasciocutaneous flaps.KEY WORDS: Blood circulation, blood flow velocity, necrosis, skin transplantation, surgical flaps     

Reconstruction of complex thoraco-abdominal defects with extended anterolateral thigh flap

Background:

The reconstruction of complex thoraco-abdominal defects following tumour ablative procedures has evolved over the years from the use of pedicle flaps to free flaps. The free extended anterolateral thigh flap is a good choice to cover large defects in one stage.

Materials and Methods:

From 2004 to 2009, five patients with complex defects of the thoracic and abdominal wall following tumour ablation were reconstructed in one stage and were studied. The commonest tumour was chondrosarcoma. The skeletal component was reconstructed with methylmethacrylate bone cement and polypropylene mesh and the soft tissue with free extended anterolateral thigh flap. The flaps were anastomosed with internal mammary vessels. The donor sites of the flaps were covered with split-skin graft.

Result:

All the flaps survived well. One flap required re-exploration for venous congestion and was successfully salvaged. Two flaps had post operative wound infection and were managed conservatively. All flap donor sites developed hyper-pigmentation, contour deformity and cobble stone appearance.

Conclusion:

Single-stage reconstruction of the complex defects of the thoraco-abdominal region is feasible with extended anterolateral thigh flap and can be adopted as the first procedure of choice.     

Unfavourable results in the repair of the cleft lip

Introduction:

Unfavorable results in unilateral and bilateral cleft lip repair are often easy to spot but not always easy to prevent as to treat. We have tried to deal with the more common problems and explain possible causes and the best possible management options from our experience.

Unilateral cleft lip repair:

Unfavorable results immediately after repair involve Dehiscence and Scaring. Delayed blemishes include vermillion notching, a short lip, deficiency in the height of the lateral vermillion on the cleft side, white roll malalignment, oro-vestibular fistula, the cleft lip nose deformity, a narrow nostril and a “high-riding” nostril. We analyze the causes of these blemishes and outline our views regarding the treatment of these.

Bilateral cleft lip:

Immediate problems again include dehiscence as also loss of prolabium or premaxilla. Delayed unfavorable results are central vermillion deficiency, a lip that is too tight, bilateral cleft lip nose deformity, problems with the premaxilla and maxillary growth disturbances. Here again we discuss the causation of these problems and our preferred methods of treatment.

Conclusion:

We have detailed the significant unfavorable results after unilateral and bilateral cleft lip surgery. The methods of treatment advocated have been layer from our own experience.KEY WORDS: Cleft lip nose, contractures, high riding nostrils, scarring, unfavourable results, vermillion deficiency     

Keystone flaps in coloured skin: Flap technology for the masses?

Introduction:

Viscoelastic properties of skin in coloured ethnic groups are less favourable compared to Caucasians for executing Keystone flaps. Keystone flaps have so far been evaluated and reported only in Caucasians. The potential of Keystone flaps in a coloured ethnic group is yet unknown.

Aim:

This article reviews the experience to reconstruct skin defects presenting in a coloured ethnic group, by using Keystone flaps, with a review of existing literature.

Design:

Uncontrolled case series.

Materials and Methods:

This retrospective review involves 55 consecutive Keystone flaps used from 2009 to 2012, for skin defects in various locations. Patient demographic data, medical history, co-morbidity, surgical indication, defect features, complications, and clinical outcomes are evaluated and presented.

Results:

In this population group with Fitzpatrick type 4 and 5 skin, the average patient age was 35.73. Though 60% of flaps (33/55) in the series involved specific risk factors, only two flaps failed. Though seven flaps had complications, sound healing was achieved by suitable intervention giving a success rate of 96.36%. Skin grafts were needed in only four cases.

Conclusions:

Keystone flaps achieve primary wound healing for a wide spectrum of defects with an acceptable success rate in a coloured skin population with unfavorable biophysical properties. By avoiding conventional local flaps and at times even microsurgical flaps, good aesthetic outcome is achieved without additional skin grafts or extensive operative time. All advantages seen in previous studies were verified. These benefits can be most appreciated in coloured populations, with limited resources and higher proportion of younger patients and unfavorable defects.KEY WORDS: Skin ethnic variations, flap success rate, flap learning curve, flap resources, Keystone flap, skin extensibility     

The indications and reliability of vein graft use in free flap transfer

BACKGROUND:

Adequate recipient vessels are critical for free flap success. There are, however, situations in which the local recipient vessels are inadequate. In these situations, vein grafts are required to allow pedicle extension to recipient vessels.

OBJECTIVES:

To determine the indications, technique, reliability and outcome of vein graft use in free flap transfer.

METHODS:

A retrospective review of 198 consecutive free flaps by a single surgeon.

RESULTS:

Vein grafts were required in 9.6% of free flaps. The most common indication was vein graft use in a planned preoperative fashion. The vein graft was most commony placed as an arteriovenous fistula loop. There was no statistically significant difference in survival between flaps with or without vein grafts.

CONCLUSION:

Vein graft use in free flap transfer is reliable, effective and often necessary for free flap survival.     

The ��reading man flap�� for pressure sore reconstruction

Background:

The treatment of pressure sores represents a significant challenge to health care professionals. Although, pressure wound management demands a multidisciplinary approach, soft tissue defects requiring reconstruction are often considered for surgical management. Myocutaneous and fasciocutaneous flaps can provide stable coverage of pressure sores.

Purpose:

Here, we describe our experience using a recent fasciocutaneous flap, which is named ‘reading man’ flap, in sacral, ischial, and trochanteric pressure sores.

Materials and Methods:

During a period of 1 year the authors operated 16 patients, 11 men, and 5 women, using the reading man flap. The ages of the patients ranged from 24 to 78 years. The location of pressure sores was 8 sacral, 5 ischial, and 3 trochanteric pressure sores. The mean size of pressure sores was 8 cm × 9 cm.

Results:

All pressure sores covered bt the Reading Man flap healed asymptomatically. After follow-up of 2-8 months, no recurrences were encountered and no further surgical intervention was required.

Conclusion:

The reading man flap was found to be a useful technique for the closure of pressure sore in different anatomic locations. The advantage of tension-free closure and the minimal additional healthy skin excision made this flap a useful tool in pressure sore reconstructions.KEY WORDS: Local flap, pressure sore, ‘reading man’ flap     

Reverse peroneal artery flap for large defects of ankle and foot: A reliable reconstructive technique

Background:

Large soft tissue defects around the lower third of the leg, ankle and foot always have been challenging to reconstruct. Reverse sural flaps have been used for this problem with variable success. Free tissue transfer has revolutionised management of these problem wounds in selected cases.

Materials and Methods:

Twenty-two patients with large defects around the lower third of the leg, ankle and foot underwent reconstruction with reverse peroneal artery flap (RPAF) over a period of 7 years. The mean age of these patients was 41.2 years.

Results:

Of the 22 flaps, 21 showed complete survival without even marginal necrosis. One flap failed, where atherosclerotic occlusion of peroneal artery was evident on the table. Few patients had minor donor site problems that settled with conservative management.

Conclusions:

RPAF is a very reliable flap for the coverage of large soft tissue defects of the heel, sole and dorsum of foot. This flap adds versatility in planning and execution of this extended reverse sural flap.KEY WORDS: Distally based peroneal flaps, extended reverse sural flaps, foot reconstruction, peroneal artery, reverse peroneal flaps     

Lip adhesion revisited: A technical note with review of literature

Context (Background):

Lip adhesion is a direct edge approximation without changing lip landmarks or disturbing tissue required for definitive closure. This converts a complete cleft into an incomplete cleft, facilitating and enhancing subsequent definitive lip and nose repair.

Aim:

The study aims to describe our technique of lip adhesion and its morbidity, and discuss the rationale for its use.

Settings and Design:

Retrospective follow-up study of complete clefts operated upon in the Bruges Cleft and Craniofacial Centre, at the supra regional teaching hospital AZ St. Jan, Bruges, between June 1, 1991 and May 1, 2009.

Methods and Material:

The group comprised 33 unilateral and 24 bilateral lip adhesion procedures. The medical files were reviewed for changes in surgical technique, morbidity, and complications and their treatment.

Results:

The lip adhesion procedure was performed at the age of two to eight weeks postnatal, and definitive lip closure, at the age of four to six months. In all cases, segment repositioning was further controlled by a palatal guidance plate. Wound dehiscence occurred in eight patients (14.0%), and three patients (5.3%) required reoperation.

Conclusions:

Although complications occurred, the beneficial effects of lip adhesion in combination with a guidance plate outweighed the risks for anatomical reconstruction of a platform for definitive lip and nose repair. Modifications are suggested to reduce these complications.

Soft Tissue Reconstruction of the Foot Using the Distally Based Island Pedicle Flap after Resection of Malignant Melanoma

Background

We report on our experience with using a distally based island flap for soft tissue reconstruction of the foot in limb salvage surgery for malignant melanoma patients.

Methods

A distally based sural flap was used for 10 cases for the hindfoot reconstruction, and a lateral supramalleolar flap was used for 3 cases for the lateral arch reconstruction of the mid- and forefoot after wide excision of malignant melanomas.

Results

The length of the flap varied from 7.5 cm to 12 cm (mean, 9.6 cm) and the width varied from 6.5 cm to 12 cm (mean, 8.8 cm). Superficial necrosis developed in four flaps, but this was successfully treated by debridement and suture or a skin graft. All thirteen flaps survived completely and they provided good contour, stable and durable coverage for normal weight bearing.

Conclusions

The distally based sural flap is considered to be useful for reconstructing the hindfoot, and the lateral supramalleolar flap is good for reconstructing the lateral archs of the mid- and forefoot after resection of malignant melanoma of the foot.     

Outcome of free digital artery perforator flap transfer for reconstruction of fingertip defects

Background:

Fingertip defect can be treated with many flaps such as random pattern abdominal flap, retrograde digital artery island flap, V-Y advancement flap, etc. However, swelling in the fingertip, dysfunction of sensation, flexion and extension contracture or injury in the hemi-artery of the finger usually occurs during the recovery phase. Recently, digital artery perforator flaps have been used for fingertip reconstructions. With the development of super microsurgery techniques, free flaps can be more effective for sensory recovery and durability of the fingertip.

Materials and Methods:

Six cases (six fingers) of fingertip defects were treated with free digital artery perforator flaps of appropriate size and shape from the proximal phalanx. During surgery, the superficial veins at the edge of flap were used as reflux vessels and the branches of the intrinsic nerve and dorsal digital nerve toward the flap were used as sensory nerves. The proximal segment of the digital artery (cutaneous branches) towards the flap was cut off to form the pedicled free flap. The fingertips were reconstructed with the free flap by anastomosing the cutaneous branches of digital artery in the flap with the distal branch or trunk of the digital artery, the flap nerve with the nerve stump and the veins of the flap with the digital artery accompanying veins or the superficial veins in the recipient site.

Results:

Six flaps survived with successful skin grafting. Patients were followed up for 6-9 months. The appearance and texture of the flaps was satisfactory. The feeling within the six fingers recovered to S4 level (BMRC scale) and the two point discrimination was 3-8 mm.

Conclusion:

Free digital artery perforator flap is suitable for repairing fingertip defect, with good texture, fine fingertip sensation and without sacrificing the branch of the digital artery or nerve.
