Abstract：Objective To report characteristic symptoms and physical signs of benign tumors of the infratempo-ral fossa(ITF)with otitis media with effusion(OME)as the initial symptom,as well as outcomes of endoscopic transna-sal and transoral tumor resection.Methods Cases of benign tumors of the ITF,grouped based on presence of OME(with OME n=12;without OME n=14),were retrospectively analyzed,including tumor volume and location in the ITF,and factors leading to OME.Outcomes of endoscopic transnasal and transoral surgery were summarized.Results There was no clear correlation between the tumor volume and occurrence of OME(P=0.1292),but tumor volume was correlat-ed to occurrence of nasopharyngeal mass(P=0.0083).Pathological type of tumor was not correlated with occurrence of OME,but the primary site of tumor in the ITF was,with tumors in the B1 and C regions more likely to cause OME.Conclusion OME can be the early or only clinical symptom of ITF tumors while nasopharyngeal examination may be unremarkable.Imaging examination can help reduce missed diagnosis.Transnasal or transoral surgery can be selected based location of the tumor in the ITF.It produces consistent long-term outcomes and is worthy of clinical adoption.
