Mucormycosis; is a rapidly progressive fungal infection due to filamentous fungi of the mucoraceae family. In this case report, we aimed to present the diagnosis and treatment modalities of a patient who developed rhinoorbital mucormycosis. A 54-year-old patient with a history of hypertension applied to the emergency department with a complaint of wound in the mouth that started four days ago. In the examinations performed here, the patient was diagnosed with diabetic ketoacidosis. In the examination of the patient, it was found that there was a necrotic wound on the left hard palate, a necrotic wound extending from the left inferior turbinate to the nasopharynx, and hyphae in the nasal passage. The patient underwent an aggressive debridement operation on the third day, due to the growth in the fungal culture. In the following clinical examination of the patient, ketone in the urine became negative, and his acidosis status improved. On the same day, the patient was treated with a positive coronavirus disease-2019 (COVID-19) polymerase chain reaction. After 15 days of treatment, the patient died due to COVID-19 pneumonia. Mucormycosis should be doubtful in patients presenting with uncontrolled diabetes mellitus and severe sino-orbital infection. All physicians following diabetic ketoacidosis should be vigilant against this rapidly progressing disease with high mortality.

Aim:Cochlear implants (CIs) aid in language and speech development through improved hearing in patients with bilateral severe or profound hearing loss. In this study, we evaluated the outcomes of our patients undergoing CI surgery.Materials and Methods:Preoperative, perioperative and postoperative clinical and audiological findings, hearing loss etiology, surgical approach techniques, and complications were evaluated retrospectively in 31 patients (35 ears) undergoing CI surgery.Results:Thirty one patients (13 adults and 18 children) were included in the study. After posterior tympanotomy following cortical mastoidectomy, electrodes were introduced through the round window in 21 ears and via cochleostomy in 14 ears. CIs with different number of electrodes (22, 16, 12) from 3 different companies were used. No postoperative complications were observed in any of the patients. The mean free field audiogram (FFA) was 95.2±19.13 dB preoperatively and 37.8±8.46 dB postoperatively in 24 patients who attended the control visits. Postoperative hearing gains were significantly different from the preoperative values (p
