Management of Brodie bite: Note on surgical treatment

Described and illustrated by Allan G. Brodie in 1946, Brodie's syndrome corresponds to an abnormal transverse occlusal relationship in which the palatal cusps of the upper molars lie outside the vestibular cusps of their mandibular antagonists. This article covers the diagnosis, clinical presentation, etiology (and, particularly, etiopathogenesis) and evolution of this syndrome, and also its management, which is often difficult. The main limitations and difficulties of orthodontics and surgery are presented, along with the surgical techniques used. These points are illustrated by some clinical cases highlighting the importance of three-dimensional analyses and 3D planning.

Surgical management of vascular anomalies in children at a tertiary care hospital in a resource-limited setting: a Tanzanian experience with 134 patients

BACKGROUND

Vascular anomalies pose major diagnostic and therapeutic challenges among pediatricians and pediatric surgeons practicing in resource limited countries. There is paucity of published data regarding this subject in Tanzania and Bugando Medical Centre in particular. This study describes our experiences on the challenges and outcome of surgical management of childhood vascular anomalies in our environment.

METHODS

Between January 2009 and December 2013, a prospective study on the surgical management of vascular anomalies was undertaken at Bugando Medical Centre.

RESULTS

A total of 134 patients (M; F = 1:2.5) were studied. The median age at presentation was 6 years. Of the 134 patients, 101 (75.4%) were diagnosed as having vascular tumors and 33 (24.6%) had vascular malformations. The head and the neck were the most frequent anatomical site recorded as having a tumor (56.7% of patients). Out of 134 patients, 129 (96.3%) underwent surgical treatment. Failure to respond to non-operative treatment (86.8%), huge disfiguring/obstructing mass (4.7%), infection (3.1%), ulceration (3.1%) and hemorrhage (2.3%) were indications for surgical intervention. Tumor excision and primary wound closure was the most common type of surgical procedure performed in 80.6% of patients. Surgical site infection was the most frequent complications accounting for 33.8% of cases. Mortality rate was 1.5%. Tumor excision and primary wound closure gave better outcome compared with other surgical options (p < 0.001). Outcome of injection sclerotherapy in 3 (3.7%) children, serial ligation of feeder vessels employed in 2 (1.6%), and conservative treatment in 5 (3.7%), were poor and required conversion to surgical excision. Despite low mortality rate recorded in this study, but ugly scar, 14 (20.6%) and limb deformity, 6 (8.8%) were problems. The overall result of surgical treatment at the end of follow up period was excellent in 108 (87.1%) patients.

CONCLUSION

Surgical excision and primary wound closure gave good outcome which could be employed in complicated and vascular anomalies which failed to respond to other treatment in regions with limited resources.

[Head and neck superficial venous malformations]

Management of vascular malformations and vascular tumors has recently been maximized by the establishment of an accurate clinical and histological classification and by the development of multidisciplinary expert consultations. Head and neck localizations of venous malformations are common, thus maxillo-facial surgeons should be aware of the characteristics of this pathology and the principles of its management. Diagnosis is mainly clinical and must be certified by Doppler-ultrasonography and contrast enhanced magnetic resonance imaging with T2 fat-saturation sequence. Therapeutic decision depends on the volume of the lesion, and on functional, cosmetic and psychological complaints. Sclerotherapy is now the preferred treatment of head and neck venous malformations. It is performed in specialized interventional radiology units by intralesional injections of sclerosing solution under fluoroscopic guidance. Surgery is useful in some cases, either on its own or following sclerotherapy. In case of bulky lesion, it is necessary to search for and prevent a severe coagulopathy before planning any intervention.

The use of propranolol for complicated infantile hemangiomas

OBJECTIVE

To assess propranolol efficacy and safety in complicated infantile hemangiomas in two different age groups.

PATIENTS AND METHODS

We report on 68 infants with infantile hemangiomas treated with oral propranolol at the lowest effective dose at different ages for a period of six months. Inclusion criteria were life-threatening hemangiomas, function-threatening hemangiomas, facial hemangiomas with risk for disfigurement, and extensive and ulcerated hemangiomas. A previously designed safety protocol was applied to all patients. The evolution of all hemangiomas since baseline (pre-therapy) until the end of follow-up was assessed on the basis of clinical features (color, palpable softening, size, and volume) and taken at follow-up visits.

RESULTS

Our results showed that propranolol was effective in arresting the proliferative phase and in accelerating the involution of infantile hemangiomas in 92.6% of cases. Propranolol efficacy was clear even when it was started after 12 months of life at low dose; after discontinuation of therapy there was a moderate-to-severe regrowth in 9.3% of cases and a mild regrowth in 22.5%. No adverse events were observed.

CONCLUSIONS

Propranolol should be used as first-line medical treatment in all cases of complicated infantile hemangiomas.

Sclerotherapy for vascular malformations in the oral and maxillofacial region: treatment and follow-up of 66 lesions

PURPOSE

The aim of the present study was to relate the use of 5% monoethanolamine oleate in sclerotherapy for vascular malformations and to suggest a protocol for its use.

PATIENTS AND METHODS

A total of 53 patients with 66 vascular malformation lesions were treated with an intralesional injection of 5% monoethanolamine oleate at 0.1 mL/cm of lesion with at least a 15-day interval and as many as 4 applications. A descriptive statistical analysis was performed using SigmaPlot, version 9.0, software.

RESULTS

The treatment with the protocol suggested was effective in 65 cases, and in 1 case, surgical intervention was required.

CONCLUSIONS

Sclerotherapy was effective in the treatment of vascular malformations, and the method chosen was adequate for lesion resolution without complications.

Sclérose percutanée des malformations veineuses superficielles : étude rétrospective de 68 cas

PURPOSE

To evaluate the efficacy of percutaneous sclerotherapy for the treatment of venous malformations (VMs) with regards to cosmetic and functional outcome as a function of their size and to review the complications.

MATERIALS AND METHODS

A retrospective study was performed between January 1997 and January 2002 on 68 patients (45 females and 23 males) ranging in age from 3 to 60 Years at the CHRU of Tours.

RESULTS

Percutaneous sclerotherapy was a very effective treatment for small and medium-size VMs, for which the aim was to achieve cure. Aetoxisclerol and Ethibloc are the sclerosing agents used. They were associated with minimal side effects and no major complication. For larger lesions, the treatment was more complex and combined stronger and also more dangerous agents like absolute ethanol and Histoacryl. The aim was then a decrease of cosmetic and functional problems.

CONCLUSION

Percutaneous sclerotherapy with Aetoxisclerol, Ethibloc, absolute ethanol or Histoacryl, either alone or before surgery, is a safe and effective method of managing soft-tIssue venous malformations.
