the distally based lateral arm flap for intraoral soft tissue reconstruction
Head and Neck-journal for The Sciences and Specialties of The Head and Neck, 1997Co-Authors: Pierre Vico, Bruno CoessensAbstract:Background: The radial forearm flap is probably the most frequently used among free flaps for intraoral soft tissue reconstruction. However, this flap is not always available. The other fasciocutaneous flaps may be too bulky or less pliable or may have a short vascular pedicle; their use is therefore less than ideal. We present a variant of the lateral arm flap located distally to the lateral epicondyle and having the same advantages as the radial forearm flap. Methods: Vascular study (dissection and radiography) was previously undertaken to determine the vascular anastomotic network in the epicondylar area, between the posterior radial collateral artery and recurrent arteries running in front of the lateral epicondyle. This demonstrated the possibility of taking a skin paddle on and below the lateral epicondyle, based on the proximal pedicle. Results: We used this flap on three patients for intraoral soft tissue reconstruction (tonsil, floor of the mouth, and Piriform Sinus). No complication with the flap itself was encountered. In all cases, direct closure of the donor site was possible, with no local complication. Conclusion: The distal lateral arm flap (LAF) represents an interesting and reliable altemative to the fasciocutaneous radial forearm flap. The positioning of the skin paddle over the lateral epicondyle and the proximal third of the lateral aspect of the forearm increases pedicle length, thus avoiding the use of vein grafts. Dissection is straightforward with a reliable vascular anatomy. Moreover, in this area, the limited amount of subcutaneous fatty tissue ensures easier placement and more pliability when compared with the standard LAF. Sons, Inc. Head Neck 19: 33-36, 1997.

acute suppurative thyroiditis caused by thyroid papillary carcinoma in the right thyroid lobe of a healthy woman
Thyroid Research, 2018Co-Authors: Hazuki Otani, Masakazu Notsu, Sayo Koike, Miwa Morita, Masahiro Yamamoto, Mika Yamauchi, Takahumi Fuchiwaki, Ichiro Morikura, Noriaki Aoi, Hideyuki KawauchiAbstract:The thyroid gland is resistant to microbial infection, because of its organ characteristics such as encapsulation, iodine content, and rich blood supply. Therefore, acute suppurative thyroiditis (AST), as a bacterial infection of the thyroid gland, is rarely seen. AST typically takes places on the left side the neck region in children, because of the coincidence of the left Piriform Sinus fistula, as a most common route of infection. AST is also usually seen in immunocompromised hosts. Herein, we report a rare case of AST in the right thyroid lobe of adult woman without any immunocompromised condition. A 59-year-old woman was introduced to our hospital for the further examination with fever, sore throat, and right anterior neck swelling. The patient appeared not to be immunodeficient. Neck ultrasonography showed a 47-mm, hypoechoic, heterogeneous nodule with ill-defined margins and irregular form, suggesting a right thyroid malignant nodule. Fine needle aspiration (FNA) biopsy specimen revealed numerous number of neutrophils in the background without nuclear atypia. Based on the clinical course and cytology, AST was confirmed to be diagnosed. Complete response was obtained by an intravenous administration of antimicrobial agents within a week. Image findings such as CT scan did not show any Piriform Sinus fistula. Four months later, neck ultrasonography showed a significant decrease in size of the nodule in the right thyroid gland to 27 mm, but the lesion still resembled a malignant nodule. So, FNA was repeated again and cytological examination confirmed papillary thyroid carcinoma (PTC). The patient subsequently underwent total thyroidectomy and bilateral level D1 lymph node dissection. Histological findings revealed a 20-mm PTC in the right lobe with sternothyroid muscle invasion of the tumor. This report represents a rare case of AST associated with PTC on the right side of thyroid gland, found in a healthy adult woman. The reason why AST coincided with malignant thyroid tumor is unclear. We have to take it into our account that malignant tumor may exist in the background when AST is identified on the right side of thyroid gland with a healthy subject.

patent Piriform Sinus fistula in a third branchial cleft cyst
Laryngoscope, 2010Co-Authors: Deidra A Blanks, Carol G ShoresAbstract:OBJECTIVE: To determine if a patent branchial cleft fistula is identifiable and treatable via direct laryngoscopy. BACKGROUND: Third branchial cleft cyst fistula tracts are rare. Complete surgical excision is the treatment of choice; however complications can include recurrent abscess and fistula tract formation. RESULTS: This report illustrates the use of suction cautery to close a patent fistula found within the Piriform Sinus after multiple resections. CONCLUSION: We believe thorough endoscopy should be performed with every surgical excision of branchial cleft cyst. Case Continued: The decision was made at that time to take the patient to the OR for cauterization of the fistula. The patient was taken to the OR on 7/28/09 where she underwent general anesthesia and endotracheal intubation without difficulty. A Dedo laryngoscope was inserted into the left Piriform Sinus and using a zero degree Hopkin’s rod a patent fistula was identified (Figure 2). A probe was inserted into the fistula and under direct visualization suction electrocautery was used to scar the fistula tract closed (Figure 3 and 4). The patient tolerated this procedure well and was admitted overnight for airway observation. She was discharged home on post operative day one with a soft diet for two weeks. The patient returned to clinic for follow up and underwent indirect laryngoscopy which demonstrated a well healed left Piriform Sinus and normal true vocal cord mobility. The patient is currently four months post operative without any complications.
