Brain waves spectral analysis of human responses to odorous and non-odorous substances: a preliminary study.

Objective: The aim of this study was to identify the potential electrophysiological biomarkers of human responses by comparing the electroencephalogram brain wave changes towards lavender versus normal saline in a healthy human population.

Method: This study included a total of 44 participants without subjective olfactory disturbances. Lavender and normal saline were used as the olfactory stimulant and control.

Early Transthyrohyoid Injection Laryngoplasty Under Local Anaesthesia in a Single Tertiary Center of Southeast Asia: Multidimensional Voice Outcomes.

Objective: To study the effectiveness of early percutaneous transthyrohyoid injection laryngoplasty under local anesthesia in improving voice quality in unilateral vocal fold paralysis (UVFP) patients.

Retained haemodialysis-catheter guidewire in the head and neck: a multidisciplinary team approach.

Penetrating foreign body in the head and neck can be catastrophic from injury to the constellation of vascular and neural structures in the neck. Early recognition and prompt surgical intervention is imperative to save lives. Herein, we present an unusual case of iatrogenic foreign body-a coiled guidewire embedded in the deep neck space.
