Introduction: Eustachian tube is often involved in the pathological processes of the nasal, paranasal, and nasopharynx cavities; therefore, nasal obstruction can alter Eustachian tube function (ETF). The pathogenesis of otitis media has been related to the presence of previous or concurrent nasal diseases. Objective: to study whether there are changes in middle ear pressure after sinonasal surgery. Materials and methods: 59 patients who had different nasal pathologies were subjected to History taking, Clinical examination and Tympanometry. ETF tests in the form of valsalva, Toynbee maneuvers and tympanometry had been performed the day before the operation and after 6 weeks. The postoperative middle ear pressure levels were determined using tympanometry. The middle ear pressure values obtained before and after surgery were compared to determine if there is a statistically significant result. Results: There were a significant improvement of nasal obstruction, ear fullness and tinnitus after surgery. The relation between the middle ear pressure preoperatively and at 6 weeks after removal of nasal packs showed a significant improvement in middle ear pressure (P < 0.05) in both ears. Conclusions: Sino-nasal surgery has a favorable effect on the middle ear pressure and Eustachian tube function.

Introduction: Visual and hearing impairment compromise the basic modes of communication leading to social isolation and impaired cognitive and general functions. Inconsistent results regarding the coexistence of eye and ear pathologies have been found. Objectives: The aim of this study is to assess audio-vestibular functions in patients with open angle glaucoma (OAG (. Patients and Methods: Fifty patients with OAG and 20 age and sex-matched healthy controls were included. Pure tone audiometry, immitencemetry, distortion product otoacoustic emission (DPOAEs), auditory brainstem response (ABR), and electronystagmography (ENG) were done and compared between the two groups. Results: Compared to the control group, patients with OAG had significantly elevated pure tone audiometric thresholds at all audiometric frequencies (P between 0.003 to 0.001), sensory neural hearing loss (SNHL) in 86% of the patients, lower amplitude of the DPOAEs at all tested frequencies, prolonged waves I, III and V in ABR and abnormal caloric test in 22% of the patients. Conclusions: The present study confirmed the association between SNHL and OAG. The results of PTA, DPOAEs and caloric tests suggesting that the cochlea is most probably the main site of pathology in patients with OAG.
