“…The age distribution of OH patients shows a bimodal peak in teenagers and those over 70. It is interesting that a high prevalence of OHs occurred in teenagers in this study compared to other studies (6) . Several reports have suggested that OHs occur at a younger age (2,3,13,14,(16)(17)(18)(19)(20) .…”

“…The reason for this is its large size and anti-gravity position of sinus opening, which result in decreased ventilation and negative pressure. Song et al reported 20 cases of OH in the maxillary sinus (3) .Some authors have suggested that the maxillary sinus is the site of OH in 90-100% of cases (6,14) . Our study supports that the maxillary sinus is the most frequent site of involvement (15 cases, 65%).…”

An organized hematoma of the maxillary sinus (OHMS), also known as a pseudotumor, 1) hematoma, 2) hematoma-like mass, 3) and organizing hematoma, 4) presents as an enlarging maxillary sinus mass which is associated with local bone destruction and which mimics a malignancy. However, it has been reported previously that cases of OHMS have benign clinical manifestations and do not recur or present with further complications after complete surgical evacuation. [3][4][5][6][7][8][9] Herein, we report a case of OHMS which was complicated by facial and orbital abscesses. The OHMS showed marked enlargement and extensive bone destruction that had occurred during an 8-month period. We believe that this case will facilitate an understanding of the rapid progression of OHMS, as well as outline the risks posed by the condition. CaseAn 88-year-old woman presented with a 3-month history of left-sided, recurrent nasal bleeding. She also complained of left-sided nasal obstruction, nasal purulence, and headache. The patient's medical history was unremarkable except that she had previously had a cataract of the left eye, which had caused significant visual loss. She has never taken anticoagulants such as aspirin or warfarin. Endoscopy revealed a polypoid mass which bled readily occupying the left nasal cavity. In addition, CT scans showed an expansile, heterogeneous, enhancing mass in the left maxillary sinus (Fig. 1). We assumed this was an OHMS, and planned endoscopic sinus surgery accordingly. We also intended to perform a preoperative biopsy to dismiss the possibility of a paranasal neoplasm. However, the patient declined further evaluation and was lost to follow-up. After 8 months, she sought assistance in the An organized hematoma of the maxillary sinus (OHMS) is a rare, benign lesion with locally destructive behavior. Although various clinical manifestations of OHMS have been reported previously, their associated complications and rapid progression have not yet been described. Herein, we report a case of OHMS that was further complicated by facial and orbital abscesses. Intensive treatment was necessary to prevent complications and progression of the condition.

IntroductionSinonasal organizing hematoma (OH) is a rare, nonneoplastic lesion that often presents with epistaxis, a reddish mass, and destruction of the involved sinonasal structures. Due to its rarity, the demographics, diagnostic modalities, treatment strategies, and outcomes have not yet been studied in a large, long‐term study.Materials and MethodsRetrospect cohort of 112 sinonasal OH patients treated between 1997 and 2020 in a tertiary, university hospital were evaluated. Demographics, systemic comorbidities, sinonasal surgery history, serum laboratory tests, radiological findings, and treatment results were collected. The present study aimed to assess the accuracy of preoperative computed tomography (CT), Gadolinum‐enhanced magnetic resonance (MR), and punch biopsies in detecting sinonasal OH as the most likely diagnosis. In addition, incidental differences by age and year of diagnosis were calculated using the Poisson log‐linear regression model.ResultsThe median age was 44, and 58% were male. Fewer than 20% of these cases had a chronic systemic comorbidity, bleeding tendency, or sinonasal surgery history. MR had the highest accuracy of (87%) to detect sinonasal OH as the most likely diagnosis, compared with contrast‐enhanced‐CT (53%), punch biopsy (49%), and non‐enhanced‐CT (16%) (all <0.05). Sinonasal OH incidence did not vary by age, but the yearly rate significantly increased by 1.05 times over 23 years (p < 0.05). Notably, 84% of 112 patients received surgical removal through the assistance of an endoscope, and none had substantial bleeding without preoperative embolization.ConclusionSinonasal OH was observed regardless of age, sex, systemic comorbidities, bleeding tendency, prior sinonasal surgery, or trauma. Preoperative MR gives the highest accuracy for detecting this disease. Sinonasal OH may be safely managed with endoscopic‐assisted surgery removal without embolization.Level of Evidence4 Laryngoscope, 2023
