Digital Audiometer vs. Conventional Audiometer (Gold Standard): Study of Tonal and Vocal Recognition Thresholds

According to the WHO (February 2, 2024): More than 5% of the world's population, or 430 million people (including 34 million children), need rehabilitation services due to disabling hearing loss. It is estimated that 700 million people will be affected by 2050, or one in 10 people. It is estimated that by 2050, nearly 2.5 billion people will have some degree of hearing loss. In most cases, audiometric testing involves determining the patient's tonal thresholds and speech recognition thresholds. The Hearing Space device is a digital audiometer that can perform both tonal and speech audiometry. This device stands out because it allows users to calibrate its transducers themselves via a guided, automated procedure. This procedure ensures that the calibration complies with the relevant calibration standards.

Otological Study of Facial Cleft Patients Over 10 Years of Age (Excluding Isolated Cleft Lip) (EFEOF)

Studies published on the placement of transtympanic ventilatory tubes in children with cleft palate show heterogeneous results, highlighting the need for a new study with strong statistical power and long-term follow-up to clarify the real benefits of this intervention. Mirashrafi (2022) and Maina (2022), for example, emphasize the current uncertainties regarding the management of otitis media with effusion in children with cleft palate. Mirashrafi conducted a study on 40 children and found no significant difference between those with a complete cleft palate and those with an incomplete cleft palate in terms of middle ear status after the placement of transtympanic ventilatory tubes. Maina, in an ongoing review, identified a lack of consensus on the optimal management of chronic otitis media with effusion, with outcomes being varied and often of low methodological quality. The absence of convincing evidence justifies the need for further research to establish clear guidelines. The objective is to study the otological status of patients based on the presence or absence of ENT surgical management involving the placement of transtympanic ventilatory tubes.
