Comparative evaluation of chorion allograft and sub-epithelial connective tissue autograft for the treatment of isolated mandibular recession with laterally closed tunnel (LCT) technique- A pilot study

Mandibular recession remains challenging because of anatomical limitations, including frenulum attachment, tooth position, and vestibular depth. The laterally closed tunnel (LCT) technique offers a minimally invasive approach for root coverage....

Discussion

Signed responses from readers of the wire.

✦ Clinical Takeaway ✦

No actionable change — this is a periodontal surgery pilot study with no relevance to audiology clinical practice.

✦ Why It Matters ✦

This article does not matter to the audiology field; it is a dentistry/periodontics study on gum recession treatment that appears to have been included in error.

✦ Key Points ✦

01Pilot study comparing chorion allograft vs. sub-epithelial connective tissue autograft for gum recession.
02Uses the laterally closed tunnel (LCT) surgical technique on the lower jaw.
03Published in the Journal of Indian Society of Periodontology (JISP), 2026.
04Small sample size typical of pilot designs; results are preliminary.
05No connection to hearing, audiology, or hearing healthcare.

Impaired speech-in-noise perception in individuals with a history of hearing symptoms after noise exposure

Audiologists should consider supplementing standard audiograms with speech-in-noise testing for patients reporting noise-exposure symptoms, as normal thresholds alone may miss clinically meaningful hearing dysfunction consistent with cochlear synaptopathy (hidden hearing loss).

Increased listening effort and decreased speech perception at high presentation sound levels in older hearing-impaired adult listeners

Audiologists should avoid assuming that higher presentation levels always benefit older hearing-impaired listeners; fitting and counselling protocols should account for the paradoxical degradation in speech perception and increased listening effort at high levels.
