"Submarine-Shaped" Radial Forearm Flap for Simultaneous Reconstruction of Oral and Lower Lip Defects".

BACKGROUND: Reconstruction of the oral cavity commonly results in trismus and lip incompetence. AIM AND OBJECTIVES: In this study, we aim to describe an innovative design of a radial forearm free flap for resurfacing bilateral buccal defects and simultaneous functional lower lip reconstruction in a single stage. MATERIALS AND METHODS: Between January 2010 and December 2019, 6 males underwent simultaneous buccal and lower lip reconstruction with a radial forearm free flap. The mean age of the patients was 57.3 years (range, 50-68 years). The defects were caused by trismus release and due to previous treatments. The mean size of the defects was 17.9 cm in length and 3.25 cm in width. Flaps were harvested, including the proximal perforators of the radial vessels, and the inset began in the buccal area opposite the anastomosis side. RESULTS: Flap size ranged from 16 to 21 × 2 to 4 cm. The recipient vessels used were the superficial temporal (4) and facial (2). All flaps survived. Lip infection was seen in 2 cases and managed conservatively. The mean follow-up was 19.2 months (range, 12-28 months). The mean increase in the interincisal distance was 10.7 mm. Oral continence was good in all patients. Speech intelligibility was considered total in 4 patients and partial in the remaining 2. CONCLUSION: The radial forearm flap constitutes an option for simultaneous lower lip reconstruction and resurfacing of bilateral buccal areas after trismus release. The procedure provides a thin and pliable reconstruction using only 1 donor site and 1 set of recipient vessels.

Microsurgical Reconstruction of Extensive Lower Lip Defects: An Algorithm for Free Flap Selection and Functional Outcomes.

BACKGROUND: Large defects of the lower lip pose a difficult challenge for any reconstructive surgeon. When there is limited local tissue available to resurface the defects, free flaps are the preferred option. AIM AND OBJECTIVES: We reported our experience in the reconstruction of extensive lower lip defects. The authors propose a new algorithm for microsurgical technique selection and assessment of the functional outcomes obtained. MATERIALS AND METHODS: A retrospective review of all microsurgical reconstructions of extensive lower lip defects by the senior author for 10 years was performed. The functional outcomes assessed included speech, feeding, and oral continence. Patients were stratified according to their status of simultaneous mandible resection (none, marginal, segmental). RESULTS: Fifty-one patients were included in this study. Almost all patients (96.1%) achieved intelligible speech. Only 1 patient experienced severe drooling. Most patients could eat a solid or soft diet (72.5%). Mandible resection was associated with the worst feeding outcomes. CONCLUSIONS: Microsurgical reconstruction of extensive lip defects is safe and provides good results. Free flap selection should take into account the location of the defect, the resected structures, and the body mass index of the patient. Feeding status seems to be inversely correlated with the amount of mandibular resection.

Ulcerating stasis dermatitis of the forearm associated with arteriovenous graft and central vein stenosis.

INTRODUCTION: Stasis dermatitis is a pathologic condition of the skin that most commonly occurs in the lower limb, where it is caused by chronic venous insufficiency. Stasis dermatitis of the upper limb is rare. CASE REPORT: A 45-year-old male, resident in Angola, presented to the emergency department with an ulcer encompassing the entire left forearm. Past medical history comprised arterial hypertension and end stage renal disease treated with hemodialysis. Dialysis access consisted of a left brachial-basilic AV graft obtained 4 years before. The patient also reported that a right internal jugular vein catheter was used previously during the maturation of the left brachial-basilic AV graft. Stenosis of the left brachiocephalic vein was documented at angiography. Angioplasty was performed, with complete resolution of the wound 2 months after admission. CONCLUSION: The differential diagnosis of extensive ulcer of the forearm must include neoplasms, cellulitis, and/or deep tissue infection with secondary ulceration, but it is also important to maintain suspicion for venous stasis syndrome as a rare but possible cause of these lesions.

Streptococcus anginosus and Phalangeal Osteomyelitis: An Unusual Presentation.

INTRODUCTION: Osteomyelitis of the hand is a rare entity and almost always occurs after catastrophic injuries. Streptococcus anginosus is a part of the normal microbial flora of the oral cavity and the gastrointestinal tract. It is frequently associated with purulent infections in several anatomic locations but rarely harms bony structures. The occurrence of osteomyelitis of the hand caused by this microorganism is very unusual. CASE REPORT: We report the clinical case of a 58-year-old Caucasian male, ex-smoker, with a medical history of a chronic hepatitis C virus infection, liver cirrhosis, and diabetes mellitus that developed extensive osteomyelitis of the middle and distal phalanx of his right ring finger caused by S. anginosus and needed amputation for infection control. He had suffered a cut with a steel grinder on that finger 2 weeks before coming to the emergency department. He was also had been submitted to a dental procedure (tooth extraction) the exact day before the trauma. We believe that the most likely origin of the osteomyelitis was a transient bacteremia caused by the dental procedure that led to hematogenous seeding of several oral commensal microbes, including S. anginosus, that ended up infecting an area with low immune capacity due to the trauma. CONCLUSION: S. anginosus causes purulent infections in multiple locations and affects more often immunocompromised patients, especially those with cirrhosis and diabetes mellitus. Even though it is not often associated with osteomyelitis, we should have a high level of suspicion if the patient has an intraoral disease or a history of dental or gastrointestinal procedures. The infection is severe, often leading to the need for radical debridements.

Isolated Trapezoid Fracture in a Boxer.

BACKGROUND Trapezoid fractures are very uncommon, accounting for less than 1% of all wrist fractures. Isolated fractures of this bone are even more rare, with just a few reports in the literature. The trapezoid bone has a very stable position within the wrist, forming a relatively immobile joint with the second metacarpal base distally. It is also connected by very strong ligaments to the trapezium, capitate and, scaphoid. Trapezoid fractures occur when a strong bending or axial force is applied to the second metacarpal base. CASE REPORT We present a clinical case of an isolated, non-displaced, trapezoid fracture in a young white male, which was treated with cast immobilization for 4 weeks and physical therapy. Complete functional recovery was achieved 3 months after the injury, without any pain or tenderness. CONCLUSIONS Fractures of the trapezoid bone usually have a good clinical outcome. Nonetheless, we need to be very suspicious about this diagnosis since radiography is apparently normal in almost all such cases and clinical examination results may not be entirely clear.

[Hidradenitis Suppurativa: Combined Treatment with Dermal Template, Skin Graft and Negative Pressure Wound Therapy, a Case Study]. / Hidrosadenite Supurativa: Tratamento Combinado com Matriz Dérmica, Enxerto de Pele Parcial e Vacuoterapia, um Caso Clínico.

Hidrosadenitis supurativa is a chronic inflammatory disease with great physical and psychological impact. Although conservative treatments may be effective in mild forms of the disease, extensive surgical resection and reconstruction are necessary in more severe forms of the disease. The purpose of this paper is to describe our two-stage reconstructive procedure regarding this kind of disease. We present a clinical case of a patient with severe, bilateral axillary hidrosadenitis. In the first surgical step we excised the lesions and applied the artificial dermis secured with negative pressure wound therapy. In the second step we used a split thickness skin graft to close the wound and again applied negative pressure wound therapy. The graft take was very good, without complications. The cosmetic outcome is acceptable and shoulder mobility was not compromised. No recurrence was detected (nine months follow up).

A hidrosadenite supurativa é uma doença inflamatória crónica com grande impacto a nível físico e psicológico. Apesar de tratamentos conservadores serem utilizados em casos de doença ligeira, nos casos mais graves preconiza-se a excisão alargada da área afetada e posterior reconstrução. O objetivo deste trabalho é descrever o nosso procedimento reconstrutivo em dois passos para o tratamento deste tipo de lesões. Apresentamos o caso clínico de uma doente com hidrosadenite axilar bilateral grave. Num primeiro tempo cirúrgico realizámos a excisão alargada das lesões e cobrimos o defeito com uma matriz de regeneração dérmica sob vacuoterapia. Num segundo tempo cirúrgico realizou-se a cobertura com enxerto de pele parcial sob o qual se aplicou, novamente, vacuoterapia. Os enxertos ficaram completamente integrados. O aspeto estético final é aceitável e não foram observadas limitações funcionais. Não foi detetada nenhuma recorrência (follow-up de nove meses).
