 \nBeyond hyperacusis: re-framing tonic tensor tympani syndrome as a middle-ear muscle dysregulation disorder in tinnitus clinics  \nAsra Amjad, MBBSa , Heena Arshad, MBBSb , Raghabendra Kumar Mahato, MBBSc ,*, Umair Ali, Pharm Dd  \nDear Editor,  \nMiddle-ear muscle (MEM) dysfunction is implicated in subsets of tinnitus and hyperacusis; TTTSdescribes dysregulated (often tonic) activity of the tensor tympani (TT) muscle contributing to sound intolerance and somatic ear symptoms[1,2] . Recent clinicbased prevalence: in a Singapore ENT–audiology tinnitus service, 13% of patients metTTTS criteria; among those who returned for follow-up, 94% showed improvement in Tinnitus Handicap Index (THI) grade with standard tinnitus management[1] . Earlier multiclinic data in tinnitus/hyperacusis cohorts reported high rates of TTTS-consistent symptom clusters (e.g., ear pain, aural fullness, fluttering) suggesting under-recognition in mainstream ENT practice[3] . TTTS remains neglected due to lack of consensus diagnostic criteria, limited objective tests, and conflation with broader “middle ear myoclonus” entities[4,5] . TT muscle participates in the middle-ear muscle reflex and modulates ossicularchain impedance; proposed roles include protection from selfgenerated and external sounds and startle-linked responses[2,6,7] . Evidence supports both phasic (myoclonic) and tonic contraction patterns; interactions between eustachian tube mechanics and MEM activity are hypothesised but remain poorly quantified[2,4] . Neural substrates involve brainstem circuits mediating MEM reflexes; however, definitive biomarkers or electrophysiological signatures for TTTS are lacking[7] .  \nNo universally accepted diagnostic criteria; paucity of objective measures of TT Contraction (e.g., real-time impedance/laser vibrometry); mechanisms linking acoustic shock,hyperacusis, and trigeminal/autonomic arousal to sustained TT hyperactivity  \naDepartment of Medicine, Islamic International Medical College, Riphah International University, Rawalpindi, Pakistan, bDepartment of Medicine, Sargodha Medical College, Sargodha, Pakistan, cDepartment of Medicine, Gandaki Medical College Teaching Hospital and Research Center, Pokhara, Nepal and dDepartment of Pharmacy, University of Swabi, Swabi, Pakistan  \nSponsorships or competing interests that may be relevant to content are disclosed at the end of this article.  \n*Corresponding author.
