===== Observational cohort studies =====

One hundred seventy-three patients diagnosed with unilateral [[vestibular schwannoma]] operated via the [[retrosigmoid approach]] were included in a study from the [[People's Liberation Army General Hospital]] [[Beijing]].
All patients underwent relevant [[examination]]s and completed the [[Tinnitus Handicap Inventory]] scale before surgery and 6 months after surgery. The [[prognosis]] of tinnitus was evaluated according to the changes in THI.

Of the 129 preoperative [[tinnitus]] patients, postoperative tinnitus resolved in 12.4%, improved in 29.5%, remained unchanged in 28.6%, and worsened in 29.5%. 18.2% of 44 patients without preoperative tinnitus appeared new-onset tinnitus postoperatively. Thirty-six patients never had tinnitus. Patients with smaller tumor sizes (≤ 3 cm) were more likely to experience preoperative tinnitus. Younger patients and those with [[serviceable hearing]] preoperatively were more likely to report their tinnitus unchanged or worsened. A new onset of postoperative tinnitus in the preoperative non-tinnitus group was found in better preoperative hearing function.

70% of patients had persistent [[tinnitus]] after [[vestibular schwannoma]] [[resection]]. The [[tinnitus]] [[prognosis]] was influenced by [[age]] and [[preoperative]] [[hearing]] [[function]]. Tinnitus is a bothersome symptom and is often underestimated by doctors. Assessment of tinnitus is mandatory during the [[vestibular schwannoma management]]
