INTRODUÇÃO: transplante de medula óssea (TMO) é uma opção de tratamento para doenças hematológicas, tumorais e imunodeficiências e tem sido realizado com maior freqüência. O TMO predispõe a infecções de VAS e complicações, dentre estas as rinossinusites (RS). Quimioterapia, radioterapia, infecções virais, antibioticoterapia e doença do enxerto versus hospedeiro (DECH) são fatores predisponentes para RS. OBJETIVO: Verificar freqüência das RS no TMO e relação com DECH. Tentar estabelecer qual melhor tratamento para as RS no TMO. MÉTODO: Avaliação otorrinolaringológica de 2 grupos com 35 (gI) e 24 (gII) pacientes, antes e depois do TMO; e tratados individualmente com antibióticos e/ou punção de seios maxilares e/ou sinusectomia endoscópica. RESULTADOS: Nenhum apresentou RS antes do TMO; 42,8% dos TMO do gI tiveram RS e 34%, DECH; enquanto 58% do gII tiveram RS e 25%, DECH. No total, 49% tiveram RS e 30,5% com DECH. Houve significativa maior freqüência de RS em DECH crônica. A cirurgia foi indicada para tratamento de RS no TMO com DECH crônica. CONCLUSÃO: A freqüência de RS no TMO foi de 49%; DECH crônica é um fator predisponente para RS; a sinusectomia pode ser necessária nos pacientes com DECHc e RS. INTRODUCTION: Bone marrow transplantation (BMT) is a treatment option for hematological diseases and immunodeficiency. It is frequently used today. BMT predisposes patients to upper airway infections and its complications, such as rhinosinusitis (RS). Chemotherapy, radiotherapy, viral infections, antibiotic therapy, graft versus host disease (GVHD) are rhinosinusitis predisposing conditions. AIM: to investigate RS frequence in this population and its relationship to GVHD; to try and establish the best treatment for RS in these patients. METHOD: ENT evaluation of two groups. One group with 35 patients (gI) and another with 24 patients (gII), before and after BMT. They were treated with antibiotics, maxillary sinus punction or endoscopic sinusectomy. RESULTS: none of them had RS before BMT. 42.8% from gI had RS and 34% had GVHD; in the gII, 58% had RS and 25% had GVHD. 49% from both groups had RS and 30.5% had GVHD. There was significantly more RS in chronic GVHD patients. Surgery was used to treat RS in chronic GVHD patients who underwent BMT. CONCLUSION: RS frequence was 49%; GVHD is a predisposing condition to RS; sinusectomy may be necessary to control RS in GVHD patients
