1/170. rhabdomyoma of the hypopharynx and larynx. Report of two cases and a review of the literature.Two cases of extracardiac rhabdomyoma are reported in a 54-year-old man with unexplained difficulty in breathing and in a 39-year-old man with a prolonged history of hoarseness. attention is drawn to the necessity of doing hypopharyngo-and laryngoscopy in such cases. One tumour was found in the left vallecula in the hypopharynx and the other on the left vocal cord. The literature and the histological findings in 53 cases are reviewed. It appears that this rare tumour is most frequently found in muscles derived from the pharyngeal arches. A total of 40 cases have been diagnosed during the last decade, and this increase is likely to continue in the future. It may turn out that extra-cardiac rhabdomyoma is not so rare as was first presumed.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
2/170. Vascular lesion of the masseter presenting with phlebolith.When evaluating an intramuscular soft tissue mass, a large differential diagnosis including both benign and malignant lesions must be considered. Because the treatment of these masses can range from simple observation to radical surgical excision, a minimally invasive but accurate method of diagnosis is desired. The workup should include radiographic imaging. MRI is the modality of choice for differentiating soft tissue lesions, although CT may be helpful in identifying calcifications such as a phlebolith. Although usually unnecessary, a sialogram can verify that a calcification lies within or outside the salivary ductal system. In most cases a biopsy specimen is required to confirm the diagnosis. However, if the imaging studies show characteristics consistent with a vascular soft tissue mass, the finding of a phlebolith is pathognomonic for a benign vascular lesion. If such a lesion is not causing significant cosmetic or functional disability, it can be observed without the need for invasive biopsy or treatment.- - - - - - - - - - ranking = 94.268580289484keywords = masseter (Clic here for more details about this article) |
3/170. Intramuscular haemangioma of head and neck region.Intramuscular haemangiomas are rare benign haemangiomas occurring within the skeletal muscle. These are uncommon tumours in the head and neck region and occur most frequently on the trunk and extremities. Fewer than 80 cases of intra-muscular haemangioma in the head and neck region have been reported in the literature. A case of intramuscular haemangioma of the sternocleidomastoid muscle is presented. The review of occurrence and natural history of such tumours is described and clinical and radiological presentation, histological classifications and treatment modalities are discussed.- - - - - - - - - - ranking = 2keywords = muscle (Clic here for more details about this article) |
4/170. Infantile fibromatosis of the neck with intracranial involvement: MR and CT findings.CT and MR imaging studies were performed in a 3-year-old boy with infantile fibromatosis arising from the infratemporal fossa and extending into the middle cranial fossa. On CT scans, the lesion was hyperattenuating (44-49 Hounsfield units [HU]), enhancing significantly after application of contrast material (63-66 HU). The MR images showed a multilobulated lesion of heterogeneous signal intensity. The tumor was markedly hypointense on T2-weighted images and slightly hypointense on T1-weighted images relative to brain tissue, iso- or slightly hyperintense relative to tongue muscle on both T2- and T1-weighted images, and enhanced strongly after administration of gadopentetate dimeglumine.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
5/170. Latissimus dorsi myocutaneous flap for secondary head and neck reconstruction.PURPOSE: To review our experience and results with the use of pedicled latissimus dorsi myocutaneous flap (LDMF) for secondary reconstruction in head and neck surgery. methods: Twenty-two patients had LDMF, 17 of them for secondary reconstruction. Data were collected regarding the primary surgery, primary method of reconstruction, indication for secondary reconstruction, and outcome. RESULTS: Seventeen LDMF procedures were performed for secondary reconstruction. Flap success rate was 100%. Reconstructive goals were achieved immediately in 16 (94.1%) patients. CONCLUSION: LDMF is a thin flap with a large surface area and a long pedicle that allows it to reach any region in the head, neck, and scalp. Its main disadvantages are the need for lateral positioning of the patient and the fact that its pedicle is not protected with muscle. In our experience, LDMF provides an excellent reconstructive option especially in complicated cases of secondary reconstruction. It may be used in cases where a free flap is usually used, but with significantly reduced surgical time.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
6/170. Muscle bow traction method for dynamic facial reanimation.A muscle bow traction method was developed for dynamic facial reanimation utilizing the masseter muscle and a fascial sling. The principle of this method is that the sling around the muscle pulls the oral commissure laterally and backward by the restoring force of the muscle from its relaxed position to its contracted position. The surgical procedure is simple. The sling is passed around the anterior half of the muscle so that the muscle can be bowed anteriorly at its center by the sling. One end of the sling is sutured to the center of the orbicularis oris and the dermis in front of the nasolabial fold, and the other end is sutured to the lower lip and oral commissure. This method was applied to 3 patients with facial palsy and to 1 patient with oral cancer. The restored motion of the oral commissure ranged from 5 to 8 mm when clenching the jaws. The concept of this method differs from those of other muscle transposition methods for facial reanimation in that the force acts at a right angle to the muscle contraction. The advantage of this method is that it is less invasive to the muscle and is a simpler procedure than other conventional muscle transposition methods.- - - - - - - - - - ranking = 110.62700829138keywords = masseter muscle, masseter, muscle (Clic here for more details about this article) |
7/170. De-epithelialised anterior (anterolateral and anteromedial) thigh flaps for dead space filling and contour correction in head and neck reconstruction.Anterior (anterolateral and anteromedial) thigh flaps based on the descending branch of the lateral circumflex femoral vessels provide a long vascular pedicle and a large flap without sacrificing main vessels and muscles. Twenty-eight de-epithelialized anterior thigh flaps were transferred for reconstruction of head and neck defects following tumour ablation. Two flaps were lost in patients that had previously undergone high-dose radiotherapy following free tissue transfer. Vascularised fibula, vascularised iliac bone and other tissues were combined with anterior thigh flaps in 13 cases utilising the distal end or derivative branches of the vascular pedicle. Salivary fistula was seen in only one case, although there were many minor and major complications. In five cases, double skin flaps were harvested from the ipsilateral thigh. One of these flaps was used for coverage of intraoral defects, while the other was placed in the submandibular area to fill dead space. Compared with other methods, this multi-flap method is considered to be most suitable for dead space filling and contour correction.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
8/170. The versatile anterolateral thigh flap: a musculocutaneous flap in disguise in head and neck reconstruction.In search of an alternative soft tissue free flap donor site to radial forearm flap and rectus abdominis flap in head and neck reconstruction, we used the anterolateral thigh flap for reconstruction of various defects in the head and neck in 59 patients. The aim was to demonstrate the versatility of this donor site and propose a new approach to achieve a safer flap dissection. With the exception of three cases, all defects resulted from excision of malignant tumours. The defects were categorised as full thickness defects of the mandible (33.9%), full thickness defects of the cheek (52.5%) and others (13.6%). During the flap dissection a direct septocutaneous pedicle was observed in 12% of the cases. In the remaining cases there were only musculocutaneous perforators and the flaps were raised either as a split vastus lateralis musculocutaneous flap (72%) or as a perforator flap (16%), depending on the required thickness. Total flap survival was 96.7% with one total and one partial failure and two re-explorations (3.3%). The mean follow-up time was 7.1 months (range: 1-12 months). In conclusion, the anterolateral thigh flap is a versatile and dependable flap that can be adapted to any type of defect by modifying the flap design and composition. It should be considered to be a musculocutaneous flap of the vastus lateralis muscle that can also be raised as a perforator flap. When harvested and used in this context, the flap dissection becomes very safe and consistent, nullifying the only major disadvantage associated with this donor site.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
9/170. Calcifying fibrous pseudotumor of the neck.Calcifying fibrous pseudotumor is a rare lesion of uncertain histogenesis that has a unique histologic appearance. We report herein a case of a 24-year-old woman with a mass on the right posterior side of the neck. magnetic resonance imaging with contrast showed a well-circumscribed mass between the right splenius and semispinalis cervicis muscles; the study suggested high collagen content. Simple excision was performed. The histologic findings were diagnostic of calcifying fibrous pseudotumor. Our review of 19 previously reported cases suggests that a good outcome is expected when a diagnosis of calcifying fibrous pseudotumor is made.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
10/170. MRI of fibromatosis colli.magnetic resonance imaging (MRI) appearance of fibromatosis colli has been reported in only two cases in the literature. We herein describe the MRI findings in a case of fibromatosis colli: the signal intensity of the fusiform mass on T2 weighted images was slightly less than on T1 weighted images, consistent with the presence of some fibrous tissue within the muscle mass.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
