ABSTRACT
PURPOSE: Cochlear implantation became a valid hearing rehabilitation option in common cavity deformity. This study aimed to assess the audiological and speech outcomes of cochlear implantation in common cavity deformity patients and to address the surgical aspect used in this population. METHODS: A comprehensive systematic literature review based on preferred reporting items for systematic reviews and meta-analyses (PRISMA) guideline from database inception through April 2020. Eighteen published articles including 138 patients with common cavity deformity met the inclusion criteria. These articles studied the surgical techniques and the audiological outcomes of cochlear implantation in patients with common cavity deformity in English language. RESULTS: Trans-mastoid labyrinthotomy was the common surgical approach in these patients. The average speech intelligibility rating and categories of auditory performance scores in common cavity deformity were lower than in normal cochlea subjects (p < 0.05), and non-significant (p > 0.05) compared with other types of inner ear malformations. CONCLUSION: Patients with common cavity deformity who underwent cochlear implantation showed a beneficial audiological and speech outcome. However, their performance is highly variable. Therefore, pre-operative counseling of the parents is necessary. The surgical approaches should be individualized according to clinical, radiological, and surgical findings.

Congenital cysts of the tongue base are an uncommon cause of airway obstruction. The diagnosis of upper airway cysts requires a high index of clinical suspicion. We report a case of a vallecular cyst that uniquely extended to the dorsum of the tongue, and the patient presented with airway distress. We found that this presentation may facilitate an early diagnosis, as asymmetry of the tongue can be picked up easily during proper clinical examination.Therefore, inspection and palpation of the dorsal surface of the tongue is crucial for the approach of pediatric patients with airway obstruction.
