ABSTRACT
OBJECTIVES: Our objective was to reinforce clinical knowledge of hearing impairment in KBG syndrome. KBG syndrome is a rare genetic disorder due to monoallelic pathogenic variations of ANKRD11.The typical phenotype includes facial dysmorphism, costal and spinal malformation and developmental delay. Hearing loss in KBG patients has been reported for many years, but no study has evaluated audiological phenotyping from a clinical and an anatomical point of view. METHODS: This French multicenter study included 32 KBG patients with retrospective collection of data on audiological features, ear imaging and genetic investigations. RESULTS: We identified a typical audiological profil in KBG syndrome: conductive (71%), bilateral (81%), mild to moderate (84%) and stable (69%) hearing loss, with some audiological heterogeneity. Among patients with an abnormality on CT imaging (55%), ossicular chain impairment (67%), fixation of the stapes footplate (33%) and inner-ear malformations (33%) were the most common abnormalities. CONCLUSION: We recommend a complete audiological and radiological evaluation and an ENT-follow up in all patients presenting with KBG Syndrome. Imaging evaluation is necessary to determine the nature of lesions in the middle and inner ear.

OBJECTIVES: The authors present the guidelines of the French Society of Otorhinolaryngology (SFORL) for the diagnosis of cervical lymphatic malformation in adults and children. METHODS: A multidisciplinary work group was entrusted with a review of the scientific literature on the above topic. Guidelines were drawn up, based on the articles retrieved and the group members' individual experience. They were then read over by an editorial group independent of the work group, and finalized in a coordination meeting. Guidelines were graded A, B, C or expert opinion, by decreasing level of evidence. RESULTS: The SFORL recommends that complete ENT examination should be performed to identify lesions at high risk of complication or associated with poor prognosis. In case of diagnostic doubt, especially in latero-cervical or oral floor lesions, fine-needle aspiration cytology should be performed before therapeutic decision-making. One or more validated classifications should be used to assess treatment efficacy and monitor progression. The reliability of antenatal diagnosis should be ensured by associating MRI to ultrasound. In antenatal diagnosis, the locoregional extension of the cervical lymphatic malformation should be evaluated accurately for prognosis, and associated malformations should be screened for, to guide treatment options.

Laryngomalacia is the most common laryngeal disease of infancy. It is poorly tolerated in 10% of cases, requiring assessment and management, generally surgical. Surgery often consists of supraglottoplasty, for which a large number of technical variants have been described. This surgery, performed in an appropriate setting, relieves the symptoms in the great majority of cases with low morbidity. However, few data are available concerning the objective results: preoperative and postoperative objective assessment of these infants is therefore necessary whenever possible. Noninvasive ventilation (NIV) may be indicated in some infants with comorbid conditions or failing to respond to surgical management.
