Management of parotid hemangioma in 100 children   总被引:7,自引:0,他引:7  
Most problematic infantile hemangiomas are successfully treated with pharmacological therapy. However, there are reports that hemangioma of the parotid gland responds poorly to corticosteroid and interferon. To better clarify the management of parotid hemangioma, the authors retrospectively studied the records of 100 consecutive patients, seen between 1975 and 2002. The characteristics of the tumor, including sex ratio, presence at birth, size, side, complications, and involvement of adjacent structures, were recorded. The indications for and response to treatment and the need for surgical procedures were documented and statistically analyzed. The female-to-male ratio was 4.5:1. Forty percent of parotid hemangiomas were on the right side, 36 percent were on the left, and 24 percent were bilateral. Forty-five percent of patients had a premonitory cutaneous lesion at birth. Fifty-nine percent of parotid hemangiomas ulcerated during the early proliferative phase. Eighty-eight percent involved nearby structures (ear, 70 percent; lip, 34 percent; subglottic region, 21 percent; eye, 18 percent; and nose, 3 percent). Seven percent of patients required tracheostomy, and 3 percent had signs of congestive heart failure. Seventy infants received pharmacological treatment. Sixty-seven patients were initially managed with corticosteroids; regression or stabilization was noted in 83 percent of tumors (56 of 67 tumors). Twenty-one patients received interferon: 11 in whom corticosteroid therapy had failed, seven in whom the tumor stabilized with corticosteroid therapy but further regression was needed, and three who had interferon as primary therapy. Ninety-five percent of the lesions that were resistant to corticosteroid subsequently responded to interferon alfa-2a or -2b. The overall response rate to pharmacological therapy was 98 percent. A reconstructive procedure was necessary during the involuting or involuted phase in 66 percent of patients: 92 percent had preauricular excision of redundant skin and/or fibrofatty tissue and 37 percent of patients had auricular revision. In summary, drug therapy was effective in the majority of infants with parotid hemangioma, whether given because the tumor was large, deforming, ulcerated, or involved nearby structures with functional consequences. Infantile hemangioma in the parotid gland responded to pharmacological treatment in a similar manner as hemangioma in other locations.  相似文献

Complications of systemic corticosteroid therapy for problematic hemangioma.   总被引:13,自引:0,他引:13  
Systemic corticosteroid therapy has been used to treat hemangiomas for 30 years; yet, there are no studies of possible complications. We reviewed the database of the Vascular Anomalies Center at the Boston Children's Hospital and gathered information on short- and long-term side effects in children who were given systemic corticosteroids for problematic hemangiomas. In addition, a questionnaire regarding early and late consequences was sent to the families of children who were treated with corticosteroids from 1983 to 1997. Of 300 patients with hemangiomas, 80 children were identified as having received a full course of systemic corticosteroids for problematic tumors. Complete data were collected on 62 of these children. The response rate to the questionnaire was 78 percent (n = 62 of 80). The initial dose of corticosteroid varied from 2 to 3 mg/kg/ day. Duration of therapy ranged from 2 to 21 months (mean, 7.9 months; median, 6.5 months). The follow-up interval from the cessation of therapy ranged from 6 months to 15 years (mean, 4 years; median, 3 years). Short-term complications included cushingoid facies (n = 44; 71 percent), personality changes (n = 18; 29 percent), gastric irritation (n = 13; 21 percent), fungal (oral or perineal) infection (n = 4; 6 percent), and diminished gain of height (n = 22; 35 percent) and weight (n = 26; 42 percent). A total of 91 percent of children who had diminished gain of height (n = 20) returned to their pretreatment growth curve for height by 24 months of age. One child, who was treated at another institution with a dose of 20 mg/kg/day for 6.5 months that was slowly tapered over 18 months, was petite 6 years after ending therapy. Another child treated with an initial dose of 2 mg/kg/day for 5 months was smaller than predicted at the age of 6 years, but she was born prematurely and was on ventilatory support for respiratory distress. Three children treated with the standard dose and duration were at a low percentile for weight 4, 5, and 10 years after the cessation of therapy. Statistical analysis showed a correlation between diminished gain of height with duration of therapy and age at initiation of treatment. One child had corticosteroid myopathy that resolved with cessation of therapy. We found no evidence for immunologic suppression, i.e., there was no increase in the number of bacterial infections during corticosteroid administration. In conclusion, systemic corticosteroids can be safely given to treat endangering hemangiomas in infants at doses of 2 to 3 mg/kg/day, which are slowly tapered and stopped before the age of 1 year. Short-term side effects were minor and transient, and no serious long-term complications occurred.  相似文献

Fifty-three patients with frontonasal tumors were seen in a 17 -year period. Of these patients, 33 were females (62 percent) and 50 were caucasians (94 percent). The correct diagnosis was made preoperatively in 87 percent of the cases. Eighty-five percent of the patients were children, and most of the lesions (83 percent) were developmental anomalies rather than true neoplasms. The most common lesions were dermoids (17), hemangiomas (16), and encephaloceles (9), but 13 different types of lesions were encountered. The treatment of all is surgical excision, and a cooperative effort by the neurosurgeon and the plastic surgeon is required in some cases.  相似文献

A series of 30 primary facial nerve tumors is reviewed. Most of them were benign (n = 26); there were four malignant tumors. Neoplasms originating within the temporal bone were found to have preoperative facial paralysis in 84 percent of cases; the extracranial tumors had a 35 percent incidence of preoperative facial paralysis. All tumors in this series were treated surgically--by means of a middle fossa or transmastoid approach for the intratemporal group of tumors; the extracranial tumors were removed by the technique of parotid tumor surgery with complete facial nerve dissection. All the patients with preoperative facial weakness required facial nerve transection. Facial paralysis was rehabilitated with nerve grafts, hypoglossal crossover, or muscle transfers. Because "normal" facial expression is still not attainable following repair of complete facial nerve transection, an early diagnosis, hopefully prior to total neurotmesis, is essential. All patients with unexplained facial weakness, especially that which is progressive and persistent, should have the entire course of the facial nerve investigated for the possibility of treatable etiology.  相似文献

Lymphatic malformation in the orbital cavity and surrounding region often causes disfigurement and visual problems. To better clarify the evolution and treatment of this condition, the authors studied a retrospective cohort of 42 consecutive patients seen between 1971 and 2003 and analyzed anatomic features, complications, and management. The ratio of female to male patients was 1:1. Most periorbital lymphatic malformations were noted at birth (59 percent), presenting as either unilateral swelling (60 percent) or a periorbital mass (24 percent). Sixty-two percent of lesions were on the left side. The ipsilateral cheek, temple, and forehead also were involved in 57 percent of patients. Twenty-two percent of lesions were intraconal, 30 percent were extraconal, and 48 percent were in both spaces. Forty-five percent of children had an associated cerebral developmental venous anomaly. Periorbital lymphatic malformation caused major morbidity; 52 percent of patients had intralesional bleeding and 26 percent of patients had a history of infection. Other common complications included intermittent swelling (76 percent), blepharoptosis (52 percent), proptosis (45 percent), pain (21 percent), amblyopia (33 percent), chemosis (19 percent), astigmatism (17 percent), and strabismus (7 percent). Ultimately, 40 percent of children had diminished vision and 7 percent became blind in the affected eye. Management of periorbital lymphatic malformation involved an interdisciplinary team that included an interventional radiologist, a craniofacial surgeon, and an ophthalmologist. The two therapeutic strategies were sclerotherapy (40 percent) and resection (57 percent); most patients required several interventions. A coronal approach was used for subtotal excision of fronto-temporal-orbital lymphatic malformation in 13 patients, whereas a tarsal incision was used for lesions isolated to the eyelid (n = 14). Ocular proptosis was temporarily managed by tarsorrhaphy (n = 9), but expansion of the bony orbit was needed to correct persistent proptosis (n = 8). Orbital exenteration was necessary in two patients.  相似文献

Patients with cerebral palsy who experience drooling are often isolated from social interaction. Surgical treatment is effective in reducing abnormal, profuse drooling in patients who have low cognitive function, but it has a risk of complications. In this study, a new, simple procedure using laser intervention that minimizes surgical complications is described. Forty-eight patients with cerebral palsy and persistent drooling after more than 6 months of conservative treatment were enrolled in this study. An Nd:YAG laser (1064 nm) was used for intraductal laser photocoagulation of the bilateral parotid ducts at 7 to 10 W for 10 seconds. The outcome was evaluated by questionnaire-based, semiquantitative assessments of drooling severity and frequency, collection and measurement of stimulated saliva, and salivary amylase measurement. The entire procedure was completed in 25 to 65 minutes, with a mean duration of 38.4 minutes. Early complications included transient facial swelling in all patients. Swelling persisted for 6 to 37 days (mean, 11 days). One hematoma (2.1 percent of patients), two infections (4.2 percent of patients), and two cystic formations (4.2 percent of patients) also occurred. No obvious xerostomia or visible scar was noted after the procedure. In the final assessment, a significant improvement in drooling severity (p < 0.05) and frequency (p < 0.05) was noted in the majority of cases. Forty patients (83.3 percent) demonstrated remarkable improvement in drooling severity, seven patients (14.6 percent) showed significant improvement, and one patient (2.1 percent), who was also autistic, continued to experience severe drooling after the laser procedure. The decrease in the amount of saliva produced ranged from 20 to 60 percent at 12 weeks after surgery. The decrease in the amount of salivary amylase measured ranged from 4 to 97 percent at 12 weeks after surgery (p < 0.05). In conclusion, the intraductal laser photocoagulation of bilateral parotid ducts is a simple, effective procedure for reducing drooling in patients who have cerebral palsy. This procedure minimizes risks and complications, compared with those associated with conventional surgery.  相似文献

Twenty-six cases of parotid hemangiomas seen at the Montreal Children's Hospital are reviewed. This lesion is by far the most common tumor of the parotid gland in children. In recent years, our treatment of this condition has gradually shifted toward conservatism, reserving surgical excision for the unusual case where the lesion does no show spontaneous resolution.  相似文献

Intralesional corticosteroid therapy for infantile hemangiomas   总被引:4,自引:0,他引:4  
Intralesional corticosteroid injections were performed in 31 hemangiomas in 30 infants aged 1 to 10 months at first injection. One to five injections were given, spaced 6 weeks apart. Lesions were located throughout the head and neck region, except one that was on the buttock. A mixture of betamethasone acetate and triamcinolone acetonide was used. Four lesions (13 percent) virtually disappeared, ten (32 percent) showed greater than 50 percent reduction in volume, ten (32 percent) showed definite but less than 50 percent reduction in volume, and seven (23 percent) showed little or no decrease in size. None showed further growth. All injections were performed without anesthesia, and there were not significant complications. We conclude that intralesional corticosteroid injections are safe and effective in properly selected infants with hemangiomas.  相似文献

The use of hydroxyapatite cement in secondary craniofacial reconstruction.   总被引:3,自引:0,他引:3  
Sixty-one patients underwent secondary craniofacial reconstruction for contour defects using hydroxyapatite cement over a 3-year period (20-month mean follow-up). There were 56 children, aged 2.2 to 18 years (mean, 10.7 years), 21 boys and 35 girls. This is the first series of pediatric patients in whom the use of hydroxyapatite cement has been reported. There were five adults aged 21 to 46 years (mean, 32 years), 3 men and 2 women. Thirty-one patients underwent reconstruction for secondary orbitocranial defects after surgery for synostosis, 7 after surgery for hypertelorism, 10 for posttraumatic skull defects, and 13 for a variety of other facial skeletal defects. There were seven complications (11 percent), ranging from a retained drain to postoperative seromas, all of which required reoperation without loss of the contour correction. All of the complications occurred in the first 18 months of our study. There has been excellent retention of implant volume with no recurrence of contour defects to date. We have not found any visible evidence of interference with craniofacial growth over the study period. We conclude that hydroxyapatite cement is a versatile and safe biomaterial when used for the correction of secondary craniofacial contour defects in children and adults. The coupling of antibiotics with this biomaterial may have applications in the treatment of osteomyelitis.  相似文献

Fifty-two patients with cavernous hemangiomas were therapeutically coagulated by use of percutaneous copper needles. Of the 52 patients, 32 had cavernous hemangiomas of the face and neck and 20 had cavernous hemangiomas of the trunk and extremities. All have gained effective treatment. Through in vitro tests, animal experiments, and clinical studies, I have confirmed that copper needles produce coagulation and destruction of cavernous hemangiomas. The mechanism, indications, technique, prevention and treatment of complications, and an analysis of copper concentrations in the patients' blood are discussed. My conclusion is that this is a simple, safe, and effective treatment for cavernous hemangiomas.  相似文献

The clinical records of 125 patients undergoing treatment for posttraumatic facial deformities (PTFD) from 1979 to 1990 were retrospectively reviewed. Patients with complex fractures had a combination of at least three of the major fracture categories [Le Fort I, II, III; naso-orbital-ethmoid (NOE); zygomatic; frontobasilar; and mandibular]. Twenty-five patients (20 percent) were found to have severe posttraumatic facial deformities resulting from a complex facial fracture pattern. Sixteen were males and nine were females, and their ages at the time of our first reconstructive procedure ranged from 22 to 64 years (mean 33 years). All patients presented to our clinic with severe posttraumatic facial deformities from 1 month to 26 years (mean 5 years) after original injury. The number of prior reconstructive attempts averaged two (range 0 to 9). Arbitrary severity scores assigned by us were mild in 4, moderate in 12, and severe in 9 patients. Once treatment was initiated in our clinic, the average number of operations was 3.76 until completion (range 1 to 15). Surgical treatment was aimed first at reestablishing proper skeletal, vertical, transverse, and sagittal proportions. Once skeletal foundations were reset, the more delicate naso-orbital-ethmoid and lateral canthal relations were addressed. Of the 25 patients, 13 (52 percent) suffered a complication at some point during their surgical management. In these 13 patients, 20 complications occurred in a total of 94 operations for an overall complication rate of 21 percent. Fifteen of the 20 complications were related to infection. Skeletal abnormalities in patients with posttraumatic facial deformities can generally be corrected with current craniomaxillofacial techniques. Ultimately, an excellent result in terms of skeletal reconstruction is compromised by the status of the surrounding soft tissue. More in-depth knowledge of the nature and magnitude of the initial and subsequent soft-tissue injury will contribute to our ability to treat these disfiguring posttraumatic sequelae.  相似文献

Of all vascular anomalies, venous malformations are the most common, and they have a propensity for the head and neck. The authors retrospectively analyzed 40 patients with craniofacial venous malformations who underwent sclerotherapy between October of 1994 and June of 1996 to determine (1) the results of sclerotherapy with ethanol and/or sodium tetradecyl sulfate, (2) the types and rate of complications, and (3) whether outcome correlated with age, sex, location, size, tissues involved, morphology (lobular or varicose), venous outflow, or number of sclerotherapy sessions. The authors also reviewed the results after sclerotherapy and contour resection (n = 18). Comparisons between the results with ethanol and sodium tetradecyl sulfate and between sclerotherapy alone and sclerotherapy and resection combined were not done. The study was composed of three parts. They were (1) a review of records and imaging studies, (2) a panel evaluation of pretreatment and posttreatment photographs, and (3) a questionnaire that determined the patient's (or parent of the patient's) impression of therapy. Interrater and intrarater agreement were analyzed. Sclerotherapy was performed in an angiographic suite, under general anesthesia, using absolute ethanol and/or sodium tetradecyl sulfate. Complications of the treatment included acute blistering (50 percent), hemoglobinuria (28 percent), deep ulceration (13 percent), and nerve injury (7.5 percent). Two patients suffered transient facial paresis, and one had permanent unilateral vocal cord paralysis. Thirty patients (75 percent) were rated as having marked improvement or as being cured by all three members of the panel; 10 patients (25 percent) were rated as having no change or only slight improvement by one or more members of the panel. Interrater reliability was moderately positive, and intrarater reliability was highly positive. Thirty-seven patients or parents of patients (93 percent) responded to the questionnaire. The outcome was considered to be marked improvement or cured in 28 patients (76 percent), and nine respondents (24 percent) described only minor improvement or no change. Logistic regression analysis revealed that only male sex and number of sclerotherapeutic procedures were significant multivariate predictors of outcome. Size, location, tissues involved, morphology, or venous outflow were not determinant. In conclusion, sclerotherapy with ethanol or sodium tetradecyl sulfate is an effective and safe treatment for craniofacial venous malformations. Often, sclerotherapy has to be repeated. For extensive perioral malformations, combined sclerotherapy and resection give the best result.  相似文献

Surgical correction of drool: a comparison of three groups of patients   总被引:3,自引:0,他引:3  
Three combinations of surgical correction for drool have been evaluated and compared in patients with cerebral palsy. All groups underwent submaxillary gland resection. Sixteen patients underwent parotid duct transfer or repositioning (Wilkie-Brody), 3 patients underwent parotid duct ligation, and 22 patients were treated with a combination of right parotid duct ligation and left parotid duct repositioning. Follow-up demonstrates that there is no visual or palpable difference between ligation and relocation of the parotid duct and that the combination of ligation and repositioning of the parotid duct is preferable to either bilateral ligation or bilateral repositioning alone.  相似文献

An accessory parotid gland occurs in approximately 21 percent of human subjects. It is located anterior to the main parotid gland, usually just above Stensen's duct and connected by its own duct to the latter. Any lesions that can occur in the main parotid gland can also arise in an accessory parotid gland. For the excision of lesions of the accessory parotid gland, we prefer to turn the same cervicofacial flap used for a lateral or total parotidectomy. This permits one to fully visualize the superficial and deep main parotid segments, the trunk and the branches of the facial nerve, and the accessory parotid gland along with its duct system and Stensen's duct.  相似文献

In the Commonwealth of Pennsylvania, it is required that all children under the age of 4 years be restrained by an infant seat or car seat appropriate for their age and weight. Furthermore, all individuals riding in the front seat must be restrained by a seatbelt. This study examined the relationship between patterns of facial injuries and the use of restraining devices in the pediatric population. A retrospective analysis was performed on motor vehicle collision data submitted to the Pennsylvania Trauma Outcome Study database from 1990 through 1995. Criteria for submission included trauma patients who were admitted to the Intensive Care Unit, those who died during hospitalization, those who were hospitalized for more than 72 hours, or those who were transferred in or out of the receiving hospital. A subset of 412 pediatric patients, 15 years of age or younger, was analyzed for patterns of facial injury and the presence or absence of restraining devices. Restraining devices were categorized as a car seat or a seatbelt. Statistical analysis was performed using chi-square and Fisher's exact tests. Of the 412 pediatric patients, only 17 children were restrained with a car seat and 121 were wearing a seatbelt. A total of 30 children sustained facial fractures, and 50 children suffered facial lacerations. There was a statistically significant increase in the incidence of facial fractures with increasing age of the child (p < 0.001). Of children with facial fractures, 70 percent of those 5 to 12 years old and 90 percent of those 13 to 15 years old were unrestrained (p = 0.166). In conclusion, despite legislation mandating the use of restraints, a large proportion of children involved in motor vehicle collisions were unrestrained. Furthermore, there seems to be a direct relationship between the age of a child and the incidence of facial fractures sustained in motor vehicle collisions.  相似文献

Sodium tetradecyl sulfate, a sclerosing agent, has been used in 18 patients in the treatment of difficult hemangiomas not amenable to surgery alone, with or without adjunctive operation, in eyelid and lip lesions, in saccular and large posterior and hypopharyngeal hemangiomas, in Klippel-Trenaunay syndrome, in variceal bleeding around a Koch ileal pouch, and as an adjunct to selective embolization in a patient with a facial A-V malformation. Sodium tetradecyl sulfate was injected intralesionally in aliquots of 0.05 to 0.1 cc at multiple sites in total doses not exceeding 2.0 to 4.0 cc. Two patients showed questionable or no improvement. The remaining 16 patients experienced modest to striking improvement with only very minimal complications in the form of superficial desquamation of skin. The conclusion is, therefore, that sodium tetradecyl sulfate, used appropriately, is a safe and frequently effective agent in the treatment of hemangiomas and a number of similar or related problems. Clinical results will be presented.  相似文献

A series of 25 patients with periorbital hemangiomas was treated with intralesional corticosteroid injection. This resulted in a marked involution of the tumor in 16 patients, a moderate involution in 5 patients, and a minimal response in 4. No local or systemic complications were noted. The overall incidence of ocular complications in the form of amblyopia or strabismus secondary to the hemangiomas was 16 percent.  相似文献

Recent advances in technology have provided laser surgeons with new options for cutaneous laser resurfacing. Despite its popularity, there is limited information on the short-term and long-term side effects and complications of variable-pulsed erbium:yttrium-aluminum-garnet (erbium:YAG) laser skin resurfacing. The purpose of this study was to prospectively evaluate postoperative wound healing, side effects, and complications of multiple-pass, variable-pulsed erbium:YAG laser skin resurfacing for facial photodamage, rhytides, and atrophic scarring. Fifty consecutive patients with facial photodamage, rhytides, or atrophic scarring were treated with a variable-pulsed erbium:YAG laser. Side effects and complications relating to postoperative healing, erythema, and pigmentary changes were tabulated. Patients were evaluated at postoperative days 3 through 7 and at 1, 3, 6, and 12 months after laser skin resurfacing. The average time for reepithelialization was 5.1 days. Prolonged erythema (>1 month) was observed in three patients (6 percent). Transient hyperpigmentation occurred in 20 patients (40 percent), with an average duration of 10.4 weeks. No cases of hypopigmentation or scarring were seen. In summary, a variable-pulsed erbium:YAG laser can safely be used for the treatment of facial photodamage, rhytides, and atrophic scarring. Although more postoperative erythema is seen after variable-pulsed erbium:YAG laser treatment than is usually produced with a short-pulsed erbium:YAG system, the side-effect profile and recovery period after variable-pulsed erbium:YAG laser skin resurfacing still are more favorable than after multiple-pass carbon dioxide laser skin resurfacing.  相似文献

BACKGROUND: Cellular hemangioma is a common benign vascular neoplasm of infants and children. The lesion typically occurs within the superficial dermis, where it is recognized as a strawberry nevus. Occasionally, this neoplasm is situated within deep soft tissues of the head or neck, with a particular predilection for the parotid gland region. Fine needle aspiration cytology (FNAC) of cellular hemangioma involving the parotid gland has been reported previously, but never confirmed by cytologic findings alone. We report the first case of infantile cellular hemangioma with sufficient characteristic cytologic features to be diagnosed by FNAC. CASE: A 3-month-old male presented with a rapidly enlarging, sensitive, solid, supraparotid mass. Ultrasound and computed tomography were performed but were nondiagnostic. Subsequent FNAC of the mass demonstrated a highly cellular specimen composed predominantly of elongated spindled cells arranged in three-dimensional coils and arcades. Immunohistochemistry demonstrated the endothelial origin of the spindled cells and confirmed the diagnosis of cellular hemangioma. CONCLUSION: Deeply situated cellular hemangiomas may pose a difficult diagnostic challenge to the clinician as well as to the radiologist. The infantile variant of this tumor enlarges rapidly, simulating an aggressive malignant tumor, and is occasionally accompanied by substantial compressive symptoms. Radiographic presentation of the lesion may be that of a solid tumor mass, unlike most other hemangiomas. Precise cytologic diagnosis of infantile cellular hemangioma can be rendered on aspirated material and is crucial in planning conservative medical treatment.  相似文献
