“…Histologicamente o padrão predominante define a classificação dos osteomas em: Compacto, esponjoso e misto. O padrão compacto é originado a partir de ossificação membranosa, é composto principalmente por osso denso, já o esponjoso origina-se por ossificação endocondral, composto de trabéculas ósseas com medula fibrogordurosa inserida, e o padrão misto pode ser caracterizado como a mistura dos dois primeiros tipos 7,8 . A presença do padrão compacto é a mais prevalente entre os osteomas (80,9%) do que o padrão esponjoso (9,5%) ou misto (9,5) 8 .…”

“…Nos casos sintomáticos ou com implicações estético-funcionais o tratamento muitas vezes é a excisão cirúrgica 5 , sendo mais comum ainda a abordagem aberta 3 . No entanto em casos assintomáticos e sem repercussões o tratamento pode ser conservador, através do acompanhamento clínicoradiográfico 8 , exceto quando mais de 50% do seio está envolvido, em lesões de crescimento rápido (mais de 1 mm / ano), em caso de extensão intracraniana ou infraorbitária e de recessões esfenoidal e frontal 4 .…”

“…A recorrência de osteomas após a excisão cirúrgica é extremamente rara, e não há relatos na literatura de transformação maligna 8 , assim sendo, não se justifica nenhuma terapia cirúrgica mais agressiva como ressecção ou curetagem com terapias complementares, bem como, para o sucesso do tratamento, não necessita da remoção completa da patologia.…”

Osteoma extenso em seio maxilar: Relato de caso

Osteomas são tumores benignos, tem comportamento clínico variavel, mas normalmente exibe crescimento lento e assintomático, sendo muitas vezes diagnosticados apenas em exames radiográficos de rotina. Na variante endosteal pode encontrar-se centralmente ou dentro dos seios paranasais, sendo mais comum no seio frontal, seguido pelo etmoide, maxilar e esfenoidal. O objetivo desse trabalho é relatar um caso clínico de osteoma que acometeu o seio maxilar, e revisar os principais aspectos relacionados ao seu diagnóstico e tratamento.

Objective: To develop an appropriate method for removing giant frontoethmoidal osteomas and the immediate reconstruction of the anterior wall of the frontal sinus. Methods: Between 2016 and 2020, five patients (4 men and 1 woman) were admitted with an osteoma of the paranasal sinuses, of which three (2 men and 1 woman) were diagnosed with giant osteomas of the frontal and ethmoid region. The patients were aged 28 to 49 years. Routine clinical examinations were carried out, including collecting patient history and a CT scan of the paranasal sinuses. The giant osteomas were removed by minimally invasive transnasal endoscopic surgery with a combined anterior wall approach to the frontal sinus. The tumour size was reduced by excision with a surgical drill before removal to minimise the defect in the frontal sinus's anterior wall. The procedure was completed with the immediate reconstruction of the anterior wall of the frontal sinus using titanium nickelide mesh. Results: The length of hospital stay was 10 days. Wound healing occurred by primary intention, and the sutures were removed on the 8th day. Followup periods were between 1 month and 1 year. Follow-up examinations were carried out 1 week, 1, 6 and 12 months after hospital discharge. On the follow-up CT scans performed a year after the operation, the implanted titanium nickelide mesh was stable, the aeration of the frontal sinus was normal, and satisfactory cosmetic outcomes were reported. Conclusion: CT is the gold standard in determining the size of the osteoma, its spread, and the state of the walls of the paranasal sinuses. A combined surgical approach and debulking of the giant osteomas using a surgical drill with the immediate reconstruction of the anterior wall of the frontal sinus by titanium nickelide mesh produce favourable outcomes. Keywords: Osteoma, benign tumour, frontal sinus, surgical treatment, frontal recess, titanium nickelide mesh.

Objective: To improve the outcomes of surgical correction of upper limb dysfunction (ULD) using the latissimus dorsi flap (LDF). Methods: ULD occurred in 76 patients with Volkmann's ischemic contracture (VIC), post-traumatic soft tissue defects, and brachial plexitis in 57, 11, and 8 cases, respectively. Out of 57 patients with VIC, in 30 cases, a skin defect was observed along with severe degenerative changes in soft tissues, neurovascular bundles (NVBs) and tendons. Post-traumatic forearm defects (n=11) in 5 cases were accompanied by damage to the NVBs and tendons. In brachial plexitis, isolated injury to the musculocutaneous nerve occurred in 6 patients, and a combination of nerve lesions with radial nerve palsy – in 2 patients. Results: Transposition of LDF to the biceps brachii for the treatment of brachial plexitis, free muscle transplantation for the treatment of VIC and forearm soft tissue defects were performed in 8, 57, and 11 cases, respectively. Active forearm flexion after the muscle flap transposition was noted after 4 weeks. In contrast, after graft transplantation in VIC, the grip function restoration began after 6 months and improved within 1 year and beyond. Conclusion: Using the LDF in surgical correction of post-traumatic ULD allowed restoring the lost functions of the crushing grip and forearm flexion. For the forearm, only free flap transplantation with a relatively long period of limb function recovery is possible. In contrast, the traspositioned LDF to the biceps allows achieving the desired functional outcomes in the shortest possible time. Keywords: Upper limb, latissimus dorsi flap, Volkmann's contracture, soft-tissue defect, brachial plexitis.
