Introduction Ear, nose and throat (ENT)pathologies can present with proptosis as the early manifestation. The majority of ENT pathologies present with ocular manifestations, due to close anatomical relationship. Objective To study proptosis in ENT disorders in terms of etiology, pathogenesis, and management. Methods The present article is a prospective study conducted at a tertiary care center, in Telangana, India. Patients presenting with proptosis secondary to ENT disorders were thoroughly evaluated and subjected to surgical exploration after providing a signed informed consent. Results Sixty cases of proptosis secondary to ENT disorders have been reported. The most common cause was sinonasal squamous cell carcinoma followed by juvenile nasopharyngeal angiofibroma and allergic fungal rhinosinusitis. Conclusion Many ENT disorders can present with proptosis. Proptosis needs to be evaluated completely for proper management and to limit the morbidity associated with it.

Due to close anatomical relationship of eye with nose and sinuses it is liable to get involved secondary to sinonasal and nasopharyngeal pathology. Sinonasal and nasopharyngeal pathology may present with varied ophthalmic manifestations. Ocular involvement from sinonasal diseases occur due to direct spread to orbit, venous spread due to valveless nature of veins, cranial nerve involvement, nasolacrimal apparatus involvement and intracranial spread. The present study is to determine the sociodemographics, ocular manifestations due to sinonasal and nasopharyngeal pathology, etiological factors and routes of spread. The most common etiology in present study was sinonasal squamous cell carcinoma followed by nasal vestibulitis. The most common ocular pathology was proptosis followed by preseptal cellulitis. The most common route was erosion followed by compression and vascular. To conclude sinonasal and nasopharyngeal pathology can spread to orbit and increase the mortality and morbidity.
