Bilateral sudden sensorineural hearing loss following COVID-19 infection has rarely been reported. We encountered a 34-year-old patient with bilateral profound sensorineural loss after COVID-19 infection. After disappointing therapeutic result of high dose steroid therapy and intratympanic steroid injection, the patient experienced satisfactory auditory rehabilitation with bilateral cochlear implantation.

Recently, the most commonly used method for voice rehabilitation in total laryngectomy patients is to maintain tracheoesophageal shunt speech after inserting a voice prosthesis. One of the most common side effects, besides valve deterioration, is periprosthetic leakage due to dilatation of the tracheoesophageal shunt. Tissue implantation may be considered as one of the conservative treatments before attempting surgical treatment. When tissue implantation is attempted more than once, the treatment success rate is close to 90%. The authors experienced a case in which an 86-year-old patient developed aspiration pneumonia due to periprosthetic leakage. The patient refused surgical treatment. He was treated successfully for injecting hyaluronic acid filler 3 times and has been without a leakage for 9 months. This procedure can be considered as an alternative method to treat periprosthetic leakage.
