Extra-Oral Excision of a Buccal Fat Pad Lipoma.

Lipomas and its variants are common soft tissue tumors, and however occur infrequently in the oral and maxillofacial region. Their incidence in the oral cavity is low among all oral lesions. Oral lipoma is yellowish and soft to palpation, and histologically can be mistaken by other lipoma variants. The aim of this study is to report a case of a lipoma located at the buccal fat pad which was removed through an extra-oral access. A 43-year-old male is presenting an augmentation in the right buccal region, being a soft consistency mobile lesion with 1.5 cm of diameter, asymptomatic, and 2 years of growing. Computed tomography scan showed hypodensity compatible with adipose tissue. The lesion was removed through an extra-oral access. The lipoma described in this clinical report had an unusual location and once the lesion was very superficial an extra-oral access was the first treatment option despite the fact that was a benign tumor.Lipomas and its variants are common soft tissue tumors, and however occur infrequently in the oral and maxillofacial region.

Cicatricial Ectropion Correction in the Inferior Eyelid with Cartilaginous Tissue Graft: Case Report

Transcutaneous approaches of the lower eyelid are commonly used to provide adequate exposure of the orbital floor and zygomaticomaxillary suture during treatment of facial fractures. Cicatricial ectropion is a rare complication that results in a shortened eyelid. This condition can be temporary in some cases but when it is permanent it must be surgically corrected, aiming to restore function, improve the aesthetical outcomes and to prevent ophthalmological disorders such as epiphora and corneal ulceration. The present study describes a novel surgical approach, associated with a concomitant cartilaginous graft, to treat severe lower eyelid ectropion resultant from a previously performed subtarsal incision.

Surgical Resolution of Bilateral Hypertrophy of Masseter Muscle Through Intraoral Approach

Masseter muscle hypertrophy is an untypical anomaly with no definite cause and its diagnosis is easily completed through physical examination and imaging examinations. In some cases, patient may report signs and symptoms of well-localizated pain. However, it is generally asymptomatic and patients chief complaint is about esthetic because of facial asymmetry. In this case, surgery is carefully indicated. The aim of this article is to report a case of a male patient with no painful and functional complaints but an important unease over his facial asymmetry. Patient underwent surgery involving bilateral resection of mandibular angles and unilateral resection of masseter muscle through intraoral approach. Surgical approaches and techniques rely heavily on surgeon. There are few reports in the literature about this anomaly, but those available present several techniques. The surgeons dexterity and knowledge become extremely important, whereas this procedure is essentiallyesthetic.

Endoscopic Removal of Displaced Sagittal Intracapsular Condylar Fracture

Fractures involving the mandibular condyle are among the most common fractures of facial bones and still generate great discussion concerning therapeutic issues. Several factors have influence on the decision of treatment management of these fractures. In some patients, even when there is displacement of fractured fragments, the choice for conservative treatment is made. However, the removal of the condyle fragment may be required. In the oral surgery scope, endoscopy is a procedure used in many areas, and can be helpful to improve the visualization of surgical sites with difficult access. The endoscopic surgery brings benefits to patient such as no scar or minimal scar, lower risk to nerve damage, and decreased of surgical trauma and bleeding. In addition, according to surgeon experience, the surgery may become more dynamic. The aim of this study is to present an endoscopic technique associated with a transoral approach to remove a displaced sagittal intracapsular condyle fragment. Furthermore, to expose the advantages and benefits of this technique as well as the satisfactory results achieved.

Clinical and radiographic evaluation of maxillary central incisors exposure in patients undergoing maxillary advancement

Abstract Introduction: Patients with dentofacial deformities may undergo orthodontic or orthodontic-surgical treatment. Both modalities can affect esthetics. Objective: This study aims to evaluate clinical and radiographic changes in exposure of maxillary central incisors occurring after orthognathic surgery for maxillary advancement. Methods: A total of 17 patients who underwent orthognathic surgery for maxillary advancement between September, 2010 and July, 2011 were selected. Exposure of maxillary central incisors was evaluated clinically and by lateral cephalograms. Measurements were taken one week before and three months after surgery. Data were paired in terms of sex, age, nasolabial angle, height and thickness of the upper lip, the amount of maxillary advancement, clinical exposure and inclination of maxillary central incisor by statistical tests (CI 95%). Results: After maxillary advancement, incisor clinical exposure had increased even with relaxed lips and under forced smile. Moreover, there was a mean increase of 23.33% revealed by lateral cephalograms. There was an inverse correlation between upper lip thickness and incisors postsurgical exposure revealed by radiographic images (p = 0.002). Conclusions: Significant changes in the exposure of maxillary central incisors occur after maxillary advancement, under the influence of some factors, especially lip thickness.
