An Easy Method of Masseter muscle sling for lower lip paralysis in senile Hansen Patients / 나학회지

Background@#One of the Sequelae of facial nerve paralysis in leprosy patients is severe eye and lip deformity. Eye deformities are most common, followed by unilateral lip deviation. When there is bilateral failal nerve paralysis, the lower lip drooping may occur. The lower lip drooping makes mouth closure incomplete, so the fluid or saliva may flow out when eating. And the teeth may be exposed or even the gum may be visible, which causes serious cosmetic and functional impairments. @*Objective@#It is to evaluate the masseter muscle sling (MMS) method in the treatment of the recurrent lower lip drooping in patients with Hansen's disease. @*Methods@#In the case of masseter muscle sling, there is a traditional method of detaching, separating and raising anterior masseter muscle in half from the mandibular jaw line and fixing it to the lip muscle. However, the authors observed a 3cm gap between the anterior border of masseter muscle and the lateral edge of orbicularis oris muscle. Under the local anesthesia the nasolabial line was incised and 3-4 places were pulled up between both musle edges and plicated with a 2/0 PDS??threads the gap-space. @*Results@#During 5 years (2016-2020), there were 17 recurrent lower lip palsy patients. The mean age was 71.3 years and the ratio of male and female was 9:8. Of 17 patents, 12 received temporal muscle transfer (TMT) attached with tensor fascia lata (TFL), 2 received temporal muscle transfer attached with Alloderm, and 3 received masseter muscle sling alone. The postoperative results of corrective masseter muscle sling were satisfactory in all 17 patients and there were no serious complication and recurrence during follow-up. @*Conclusion@#Masseter muscle sling is effective method in correction of recurrent lower lip drooping in patient with leprosy who treated previously with temporal muscle transfer attached with tensor fascia lata or temporal muscle transfer attached with Alloderm. In addition, masseter muscle sling may be considered as the first-line treatment in the lower lip paralysis.

Easy method for Upper lid blepharoplasty in elderly Hansen affected persons / 나학회지

BACKGROUND@#The average age of Korean Hansen affected persons who have become less than 10,000 is 76 years old.The upper eyelid lesions of these patients coexist with senile lesions and paralytic lesions due to facial paralysis.This senile change includes skin laxity, eyebrow drooping, eyelid drooping, medial and lateral canthal relaxation and paralytic changes include wrinkle disappearance in the forehead, eyebrows asymmetry, eyelash drooping in the upper eyelid, and simultaneously symptoms of lower eyelid such as ectropion and lapophthalmos.@*OBJECTIVE@#Authors want to present a prescribed method of treatment that makes it easier to fix changes in senile and paralytic eyelids in elderly Hanson affected persons.@*METHODS@#For senile blepharochalasis, if the distance between eye blow and eyelash (brow-lash distance) is to the 2.5 cm or more the sub-brow resection should be done.However, if brow-lash distance is less than 2.5 cm, the supra-brow resection should be done. For paralytic cases if there is a difference in height on the eyebrow. the skin is removed to create the same level as the eyebrow height on the healthy side.if both eyes are paralyzed the supra blow skin excision are done with prudence not to make the lagophthalmos.RESULT: In recent 2 years of 2018–2019we treated 32 cases of blepharochalasis, Blephnaroptosis, paralylic eyebrow droping and lash-laden eyelid margin excision for trichiasis correction. Satisfactory results were obtained in all patients who underwent surgery.@*CONCLUSION@#The authors report our experience of treating various upper eyelid lesions in the past 2 years in 32 cases of Hansen affected persons a history of Hansen's disease, together with literature review.

Two cases of calcinosis cutis treated with surgical excision / 나학회지

Calcinosis cutis is an uncommon disorder and defined as the deposit of insoluble calcium salts in the skin. It is classified as dystrophic, metastatic, idiopathic, and iatrogenic according to etiology. The dystrophic type is the most common and occurs in the previously damaged tissue, including connective tissue diseases, panniculitis, inherited disorders, benign and malignant tumors, a variety of scarring caused by burn, radiation, trauma, surgery, and keloid. Treatment options are limited. Whereas medical therapy is usually not very effective, surgical intervention has shown to be beneficial and is indicated when painful masses, recurrent infection, ulcerations, functional impairment, and cosmetic concerns exist. Herein, we report two cases of dystrophic calcinosis cutis associated with longstanding, painful, ulcerated cutaneous lesions in the extremities successfully treated with surgical excision.

Aesthetic Surgical Treatment of the Peri-orbital area in Hansen's Patients / 나학회지

BACKGROUND: Upper eyelid blepharoplasty has become one of the commonly practiced aesthetic operation. This upper eyelid blepharoplasty primarily conducted in aged person, while also addressing aesthetic concerns, include methods to rejuvenate the peri-orbital area and provide unobstructed eyesight. OBJECTIVE: Methods to affect rejuvenation of the peri-orbital area are variable and depend heavily on the patients. This makes evaluation of the patient a critically important component of the treatment process. Upper eyelid blepharoplasty requires treatment of the anterior and posterior lamella structures. Anterior lamella undergone a resection of the skin and orbicularis muscle to reduce the sagging appearance on the anterior surface of the upper eyelid. The retractor structures of the posterior lamella, especially the levator aponeurosis and the Müller's muscle, are advanced, tucked and plicated to the tarsus to add tension as needed to correct the blepharoptosis. This procedure, while also addressing aesthetic concerns, primarily adds tension to reduce or eliminate eyesight obstruction. Methods & Conclusion: These operation methods include : The plication procedures of posterior membranous septum and turn-over orbital septum to 2mm below the tarsus and traditional levartor complex tucking including levator aponeurosis and Müller muscle added. In addition to blepharoplasty and blepharoptosis in aged persons the brow-ptosis may also experience. This drooping of the eyebrow also contribute to eyesight obstruction and should be corrected. In general, treatment consists of a subbrow resection when the brow-lash distance is 25mm or more. When the brow-lash distance is less that 25mm, a supra-brow excision is required to prevent an angry or harsh appearance. However, when using the supra-brow method the possibility of an unwanted visible scar is more likely, a short incision direct brow-lift could be another alternative. But short incision brow-lift procedure can only use under the normal forehead muscle function.

An effect of Masseter muscle transfer in recurred cases following temporalis transfer for lower lip paralysis / 나학회지

BACKGROUND: Facial nerve palsy in patients with leprosy brings a variety of discomfort functionally and cosmetically. Although the distortion of the lips is less frequent than that of the eyes, when it occurs, it happens either unilaterally or bilaterally and shows a different dynamic from that in eyes. The lower lip droop causes saliva to flow out of the mouth when eating and exposes the gum and teeth. MATERIALS AND METHODS: All patients were previously treated using the TMT procedure yet symptoms recurred within an unacceptable timeframe. Therefore, we retreated patients using the masseter muscle plication. We performed the masseter muscle plication to the lateral portion of the lower lip muscle to give it power without dividing the anterior segment of masster muscle from mandibular border. RESULTS: Complete closure of the mouth was observed in 6 patients with a moderate degree of lower lip droop. One patient that presented with severe lower lip droop bilaterally showed only partial closure. CONCLUSIONS: Without dividing anterior half segment of masseter muscle from mandibular border, the direct plication of the anterior border of masseter muscle and lower lip muscles was very effective method to correct the lower lip droop and to close the mouth in recurrent patients after temporal muscle transfer.

Surgical Treatment of Paraffinomas in Patients with Leprosy / 대한피부과학회지

BACKGROUND: Ulnar nerve palsy leads to thumb-web depression, hypothenar flattening, and inter-digital depression in patients with leprosy. To camouflage these deformities, patients used to inject paraffin or silicone oil into the areas of muscle atrophy associated with thumb-web depression and hypothenar flattening. After several years and decades, paraffinomas eventually resulted in extensive inflammatory fibrosis and recalcitrant recurrent ulcers at the injection sites. OBJECTIVE: The aim of this study is to compare the results of different surgical treatments for paraffinomas in patients with leprosy, and to find out the most effective treatment method that has a low recurrence rate. METHODS: Between January 2000 and December 2012, 47 patients with paraffinomas who had visited the Korean Hansen Welfare Association Hospital were enrolled to participate in the study. The number of paraffinomas was 56, and the mean age of the patients was 73 years. A retrospective evaluation of the cosmetic results and recurrence rate was performed. RESULTS: Of the 56 surgically treated paraffinomas, 30 lesions were treated using primary closure, 20 lesions were treated with skin graft, and 6 lesions were treated with skin flap. The cosmetic outcomes, which were assessed using a four-point grading scale, were excellent in 10.7% (6/56), good in 25% (14/56), fair in 38% (21/56), and poor in 28% (15/56) of the patients. There were no significant differences among the three surgical procedures with respect to the cosmetic results. The recurrence rate was 33% (10/31) in the primary closure group, 50% (10/20) in the skin graft group, and 17% (1/6) in the skin flap group. There were no significant differences in the recurrence rate among the three surgical procedures. CONCLUSION: The extensive and aggressive curettage of lesions is very important to reduce recurrence rate. When the older age of the patients is considered in conjunction with the simplicity of the operation and the total operation time, primary closure is considered the treatment of choice both cosmetically and practically.

Lid Splitting with Lash Resection for Trichiasis in Long-Standing Leprosy / 나학회지

BACKGROUND: Trichiasis is the inward inversion of the eyelash, resulting in painful contact with the cornea, which is a common symptom of patients with leprosy seeking treatment in leprosy outpatient clinics. Recurrence rates are high when trichiasis is treated with conventional methods such as epilation and electrolysis. OBJECTIVE: To evaluate prospectively a more aggressive surgical technique, lid splitting with lash resection, for trichiasis in long standing leprosy as a pilot study. METHODS: During the past 10 months, we treated 12 leprosy patients (18 eyelids) for trichiasis by splitting the lid margin at the gray line with resection of the eyelash bearing portion to modify the anterior lamellar repositioning. RESULTS: In all patients, pain disappeared immediately and there were no complications. The low number of patients and relatively short follow-up period are study limitations. CONCLUSION: The lid splitting with lash resection for trichiasis in patients with long standing leprosy is a satisfied treatment method functionally and cosmetically.

Causes and prevention of Ptosis after Temporal muscle transfer in Lagophthalmos in the Patients with leprosy / 나학회지

Facial nerve paralysis in leprosy adversely affects facial regions from the forehead to the lip. In particular, lagophthalmos in patients with leprosy causes exposure keratitis, corneal and conjunctival dryness which can progress blindness and disfigurement. The function of the eyelids is controlled by the oculomotor nerve and the facial nerve. In leprosy patients the oculomotor nerve continues to function causing the levator muscle to lift the eyelids. However, paralysis of the facial nerve prevents the orbicularis oculi muscle from closing the eyelids, resulting in lagophthalmos. Various methods were developed to correct lagophthalmos, one of which was temporal muscle transfer(TMT) reported in 1934 by Gillies. Since we noted relatively high occurrence of ptosis as a complication in patients treated previously with the TMT, we performed other surgical procedures for laglphthalmos over 15 years, not to make the ptosis. Although most of the patients quite improved post-operatively, partial lid-gap frequently persisted. It may be related to involutional changes and paralyzed orbicularis muscle. Recently, we conducted 4 different TMT methods for last 4 years to reduce ptosis. The methods used included Brown & McDowell, McCord & Codner, modified Gillies & Anderson, and modified Gillies. Seventy-five TMT operations in 60 patients(26 males and 34 females) were done between 2011 and 2014. The age range of the patients was 54~87 years(the mean was 70.1). Fifteen patients had bilateral TMT procedures. As a result, ptosis appeared in 14(18.7%) out of 75 TMT procedures for 4 years. Four technical points should be considered for the initial assessment to prevent or reduce the incidence of ptosis. The first is the increase of the length of temporalis muscle flap to approximately 8cm with a parallel course to the lateral canthus, which will reduce the oblique pull. Second, the width of the fascia sling in the upper eyelid is narrow(3~4mm) to reduce weight on the eyelid. Third, the fascia sling in the upper lid is not tied with that of the lower lid at the medial canthal tendon to reduce tension. Lastly, the fascia sling in the upper eyelid is shallow(subdermal level) in location and as near as possible to the lid margin.

Clinical characteristics and Treatment of Paraffinomas in patients with Hansen disease / 나학회지

BACKGROUND: Ulnar nerve palsy in patients with Hansen disease causes hand wasting and atrophy. To masquerade these deformities, patients injected paraffin or silicone into the lesions, which results in paraffinomas. Several years later, painful inflammation, ulceration or abscesses may develop in the paraffinomas. OBJECTIVE: To investigate the clinical characteristics of paraffinomas in patients with Hansen disease, and to evaluate and compare the effects of various surgical treatment methods of paraffinomas. METHODS: Fifty-seven patients with paraffinomas were randomized to receive debridement(curettage) with primary closure, skin graft, skin flap, or second intention at the hospital of Korean Hansen Welfare Association from 1998 to 2012. We analyzed retrospectively the final cosmetic results of three methods, primary closure, skin graft, and skin flap, in 33 patients with more than 6 months follow-up. The final results were classified into 4 grades, excellent, good, fair, and poor. RESULTS: Of 57 patients, the ratio of male and female was 42:15 and the average age was 73 and 71 years repectively. The location of the lesions was the hand and wrist in 54 patients and the face in 3. The total number of procedures was 72 and that of 3 methods was 55. In 33 patients, 19 showed above fair grades and the recurrence rate was 42%(14/33). There were no serious postoperative complications. CONCLUSION: Wide and thorough curettage as debridement was very important to reduce recurrence and the primary closure was most efficient in consideration of an old age of patient, simplicity of procedure and cosmeosis.

Comparison of static and dynamic methods in paralytic lagophthalmos treatment / 나학회지

Changes in the eye resulting from leprosy include lagophthalmos, ectropion and the eyelid retraction. In lagophthalmos, an interpalpebral gap(lid gap) of 2mm or less, which is most preferred after correction, does not have any adverse effect on the vision. However, a gap of 3mm or greater can cause or make the eye susceptible to the dryness of the cornea or other vision problems. Bell's phenomenon will adequately prevent eye damages, especially corneal damage when the lid gap is less than 3mm. Although static methods such as autogenous canthal sling, lateral tarsal strip, medial tarsorrhaphy and gold implant had a positive cosmetic effect when used in combination, the lid gap could hardly reduce to less than 3mm. Frequent recurrence of lagophthalmos and ectropion after static methods required further definite surgical treatment. We applied a dynamic method of modified Gillies to correct lagophthalmos and it was successful in reducing the lid gap to less than 2mm in most cases.

Upper Eyelid Blepharoplasty in Aged Persons

Nowadays, upper eyelid blepharoplasty is one of the most commonly practiced aesthetic operations. Different from double-fold operations mainly performed in teenagers or early twenties, the upper eyelid blepharoplasty is mainly performed in aged persons for rejuvenation by resecting an excess of skin, muscle and fat around the periorbita to enhance the eyebrow decent by sub-brow resection due to drooping of the lateral eyebrow. In addition, the upper eyelid blepharoplasty in aged persons who are often accompanied with the blepharoptosis caused by dehiscence or stretching of the aponeurosis itself to the tarsus and by non-delivery of contractile power to upper eyelid needs tucking of the levator aponeurosis and suturing the reversed septum to orbicularis oculi muscle to the inferior flap.

Surgical Correction of Paralytic deformity of the Lips in Hansen's Disease / 나학회지

BACKGROUND: Damage of the facial nerve, especially buccal and marginal mandibular branches, causes facial palsy and paralytic deformity of the lips such as lower lip ectropion, lip drooping, deviation of the mouth, inability of closing mouth, and the loss of the nasolabial folds. OBJECTIVE: To find out the best surgical method to correct paralytic deformity of the lips. METHODS: We reviewed retrospectively the various surgical treatment modalities of the paralytic deformity of the lips performed in The Institute for Leprosy Research for 13 years. RESULTS: One hundred and twenty five surgical procedures were performed in 80 patients with Hansen's disease. Of these, the static method, dermal suspension flap, was done in 15 cases, the dynamic methods were done in 64 cases, and others were done in 46 cases. All patients showed postoperatively clinical improvement above the average. Two patients received reoperation or additional procedures due to relapse of the condition. CONCLUSIONS: The dynamic method using tensor fascia lata was superior to other treatment modalities.

Review of treatment of paralytic ectropion and lagophthalmos / 나학회지

Since 1992, We have treated nearly nine hundreds cases with paralytic ectropion and lagophthalmos as a sequela of Hansen's disease. Treatment to correct paralytic ectropion was performed by already established conventional surgical methods or their minor modifications. Although most of patients quite improved postoperatively, lagophthalmos frequently remained partially. Involutional orbital changes superimposed on decreased tone of the paralyzed orbicularis muscle make the corrective effect short-lived, which in turn brings about recurrence of ectropion and lagophthalmos. Of the surgical techniques, dynamic Gillies' temporalis muscle transfer was used mostly in the early stage. After that, various static methods such as gold plate insertion, transsection of levator muscle and spacer graft in the upper eyelid, and medial tarsorrhaphy, medial canthoplasty, horizontal wedge resection, spacer graft, lateral tarsal strip and lateral canthoplasty in the lower eyelid were applied. Sometimes canthal sling with Alloderm or autologous fascia to pull upward the lower eyelid or Kuhnt-Szymanowsky flap to tighten eyelid skin was added to the surgical procedures. In future, the more sophisticated techniques must be exploited to fulfill complete eyelids closure and to lower the recurrence rate. Upgrade of canthal sling method or return to Gillies' method may be an alternative at present.

Reappraisal of the lateral tarsal strip in the treatment of paralytic ectropion / 나학회지

The imbalance between paralyzed orbicularis oculi and normally functioning its antagonists such as the levator of the upper lid and the capsulopalpebral fascia of the lower lid in patients with leprosy causes ectropion, eyelid retraction and lagophthalmos. There are a lot of surgical methods to manage the ectropion and retraction of the lower lid including lateral canthoplasty, lateral canthopexy, spacer graft, canthal sling, medial tarsorraphy as well as temporal fascia transfer. In this study, we applied the lateral tarsal strip combined with Kuhnt- Szymanowski procedure to thirty-two patients with paralytic ectropion and this method was proven to be very effective in correcting the abnormal conditions.

Eyelash Ptosis in Hansen's Disease / 나학회지

BACKGROUND: Eyelash ptosis(ELP) is a common finding in patients with long-standing leprosy. However, it has rarely been reported in the literature previously, because it has been diagnosed as trichiasis or entropion. OBJECTIVE: To determine the prevalence of ELP in Hansen's disease. METHODS: We took both frontal and lateral photographs of eyes in 20 patients and evaluated the degree of ptosis using a 4-point rating scale, in which 0 indicates no ptosis; 1, minimal; 2, moderate; and 3, severe. The evaluation was also performed in 20 normal persons as control group. RESULTS: All patients demonstrated ELP. In general, severity of ptosis in patient group is greater than that in control group. While the mean eyelash ptosis rating was 2.0+/-0.6 in the latter, it was 0.6+/-0.4 in the former, which is statistically significant (p<0.01). CONCLUSIONS: ELP is common in the patients with Hansen's disease and moderate to severe forms occurred more commonly in disease group compared with control group. ELP must be considered as a characteristic ocular finding in long-standing leprosy.

Spacer Graft Combined with Canthal Sling in Paralytic Ectropion

Lower eyelid retraction and ectropion is a result of two factors; (1) weakened intrinsic forces associated with senile change or (2) from extrinsic forces by the augmented distraction activity as a result from scar contracture after surgery, laser therapy, or trauma. Facial nerve palsy, in patients with leprosy, causes paralysis of the orbicularis muscle. Its antagonizing muscles, namely, the levator of the upper lid and the capsulopalpebral fascia of the lower lid, function as normal. This counterbalance results in lagophthalmos and retraction of the eyelids. Conventional surgical methods used to correct the ectropion and retraction of the lower lid include lateral canthoplasty, lateral canthopexy, lateral tarsal strip procedure and medial tarsorrhaphy. Recently the use of spacer graft has been incorporated in treating lower eyelid retraction. The use of spacer grafts creates separation between the tarsal plate and the capsulopalpebral fascia, to introduce materials like palatal mucoperiosteum, conchal cartilage or AlloDerm into the space between the two structures. In this study, we designed as AlloDerm or deep temporal fascia graft to function not only as a spacer graft but also as canthal sling. The use of a long spacer graft-sling to supplement the canthal sling showed superior results in elevating the lower eyelid and reducing ectropion. The use of the spacer graft in this method is more effective than other conventional methods.

Phenol peeling for treatment of deep wrinkle in leprosy patient / 나학회지

The untreated leprosy skin takes on a waxy appearance & feel full. Thickening is most marked over the face, which starts to devolp into folds, hanging down to produce the classical lion-like facies. The deep folds in disease state change to the numerous compacted shallow wrinkle with less elasticity of the skin. To correct these wrinkles of the patients healed from the leprosy, we tried the stone-VK formula application to the 14 patients, who are men 10 & women 4 in the age distribution of 55~78 years old. The use of the phenol & croton oil chemical peeling this method is more effective than other chemical & conventional surgical method to remove facial wrinkle. We need more experience of this peeling. In preliminaxy report, our superior results in removing facial wrinkle is presented.

Spacer graft using deep temporal fascia in the treatment of paralytic ectropion / 나학회지

BACKGROUND: Spacer graft is known to be a very effective surgical method in the treatment of paralytic ectropion. OBJECTIVE: This study was performed to evaluate deep temporal fascia as a spacer instead of Alloderm in spacer graft to correct paralytic ectropion. METHODS: In seven patients with the lower lid ectropion as a sequela of Hansen's disease, a strip of deep temporal fascia, 4.0cm long and 0.5cm wide, was obtained from the scalp. A separation between the tarsal plate and the capsulopalpebral fascia was made and the strip was inserted into the space. Two ends of the strip were fixed to the medial and lateral canthal ligaments respectively like a sling. RESULT: In all patients, immediate postoperative improvement was achieved, which was to the same degree in the patients treated with Alloderm previously reported. And no serious complications were observed in both donor and graft sites. CONCLUSION: As a spacer in spacer graft, patient's own deep temporal fascia shows good cost-effectiveness ratio and can be an alternative to Alloderm. However, further studies are neccessory to find out the long term efficacy, especially recurrence.

Spacer graft combined with canthal sling in paralytic ectropion(Part 2) / 나학회지

The lower eyelid descent and ectropion is resulted from either a decrease in intrinsic forces by senile change or an increase in extrinsic forces by the augmented distraction activity as a result of surgery, laser therapy, or trauma. Although facial nerve palsy in patients with leprosy causes paralysis of the orbicularis muscle, its antagonizing muscles, namely, the levator of the upper lid and the capsulopalpebral fascia of the lower lid, are functioning properly, resulting in lagophthalmos and retraction of the eyelids. There are various conventional surgical methods to correct the ectropion and retraction of the lower lid such as lateral canthoplasty, lateral canthopexy, lateral tarsal strip procedure as well as medial tarsorraphy. Spacer graft, recently introduced, is used to create separation between the tarsal plate and the capsulopalpebral fascia, and to insert maerials like palatal mucoperiosteum, conchal cartilage or Alloderm into the space between the two structures. In this study, we added to one more process to the routine procedure, canthal sling, in which two ends of lengthened Alloderm by 15mm were fixed to both canthal ligaments like a fascial sling. Spacer graft combined with concomitant cnathal sling was proven to be effective in elevating and reducing retraction of the lower lid, and to be superior to any other conventional methods.
