Patients are currently waiting 55 weeks to be seen for a routine ear nose and throat referral.
There are 1,092 patients on the waiting list, which at one point stood at 76 weeks, until weekend clinics were introduced to reduce waiting times.
A review of the waiting list has been conducted by specialists, with patients contacted to see if their symptoms have improved sufficiently enough to be discharged.
Manx Care are also undertaking a demand and capacity review to identify the gap between consultant capacity and demand from referrals to determine if additional staffing is needed.
