Intratympanic injection in sudden sensorineural hearing loss

Purpose: the aim of this study was to evaluate intratympanic corticosteroid injection in cases with idiopathic sudden sensorineural hearing loss [SSNHL]

---

Material and Methods: seventy patients with sudden onset sensorineural hearing loss [SSNHL] were included in this study; 40 females and 30 males. Their age ranged from 14 to 67 years old. The hearing loss was graded into mild, moderate, severe and profound SNHL. The patients were classified into 3 groups according to the treatment modality; Group I did not receive corticosteroid therapy and included 10 patients, group II received systemic corticosteroid therapy and included 15 patients and group III received intratympanic corticosteroid therapy and included 45 patients

---

Results: in group I, 30% of patients showed improvement and in group 11, 40% of patients showed improvement and in group III, 82% showed improvement of hearing

---

Conclusion: intratympanic corticosteroid therapy for SSNHL has a better success rate than systemic corticosteroid therapy and control patients with no treatment. It has a low incidence of complications. Patients with mild and moderate hearing loss have a better prognosis than patients with severe and profound hearing loss
