The serratus muscle (SAM) can be raised as an isolated muscular or osteomuscular flap on its nutrient vessels or in combination with a latissimus dorsi (LD) myocutaneous flap on the thoracodorsal pedicle for various reconstructive purposes. The aim of the present is to report on the results achieved after the use of the SAM alone (n = 7) and in combination with an LD (n = 3) after tumor resection or osteoradionecrosis (ORN) in ten patients with defects of the head and neck. One flap was lost due to venous thrombosis. The donor site morbidity was minimal. Emphasis is given on a new indication, namely ORN of the mandible. Short-term results show that the use of the SAM prevents a pathologic fracture in cases of a class IIIa osteoradionecrotic mandible. More extensive use of the SAM flap is advocated.

Impact of Vibrations and Rapid Decelerations on SemontPLUS Maneuver Efficacy: An In Vitro Study.
Otol Neurotol

Department of Otorhinolaryngology, Head and Neck Surgery, Inselspital, University Hospital Bern and University of Bern, Bern, Switzerland.
Objective: We aimed to investigate the effect of adding "rapid decelerations" and "vibrations" during a SemontPLUS maneuver on the dynamics of the inner ear and the success rate of canalolithiasis repositioning.
Methods: We used a previously described upscaled (5×) in vitro model of the posterior semicircular canal of the inner ear to analyze the trajectory of a single and clumped surrogate otolith particle (metallic sphere) during a SemontPLUS maneuver (-60 degrees below earth horizontal) on a repositioning chair (TRV). We compared the angular displacement of these particles with and without the application of "vibrations" or "rapid decelerations" using TRV.
Hearing care in low-resourced and humanitarian settings: findings from a pilot study in South Sudan.
Int J Audiol

Cochlear Center for Hearing and Public Health, Johns Hopkins University, Baltimore, MD, USA.
Objectives: This longitudinal experimental study aimed to profile audiometric hearing loss, explore the feasibility and efficacy of low-cost hearing devices, and examine their social and emotional impact on participants in South Sudan, a low-resource humanitarian setting.
Design: We performed pure tone hearing screenings on adults with self-reported hearing disability, randomly providing eligible participants with one of two inexpensive devices-Asana Pro 800, a non-customizable hearing device fit unilaterally, or the Super Ear SE9000, a hand-held amplifier with headphones given one per individual.
Study Sample: Between October 2022 and January 2023, 142 adults underwent hearing screening at the Juba Teaching Hospital ENT clinic, of whom 19 eligible individuals were provided with hearing devices.
Pitch perception in school-aged children: Pure tones, resolved and unresolved harmonics.

Pitch perception affects children's ability to perceive speech, appreciate music, and learn in noisy environments, such as their classrooms. Here, we investigated pitch perception for pure tones as well as resolved and unresolved complex tones with a fundamental frequency of 400 Hz in 8- to 11-year-old children and adults. Pitch perception in children was better for resolved relative to unresolved complex tones, consistent with adults.

Characterization of Optokinetic Nystagmus in Healthy Participants With a Novel Oculography Device.
Otolaryngol Head Neck Surg
January 2025
Department of Otolaryngology-Head and Neck Surgery, Massachusetts Eye and Ear, Harvard Medical School, Boston, Massachusetts, USA.
Objective: To develop a proof-of-concept smart-phone-based eye-tracking algorithm to assess non-pathologic optokinetic (OKN) nystagmus in healthy participants. Current videonystagmography (VNG) is typically restricted to in-office use, and advances in portable vestibular diagnostics would yield immense public health benefits.
