Craniofacial abnormalities are associated with mandibular hypoplasia, reduced mandibular space with overcrowding of soft tissues and maxillary hypoplasia. Decreased mouth opening and limitation in jaw protrusion are independent predictors of difficult airway in such patients. The relative difficult problem becomes even graver in the paediatric age group because of their small mouth opening and un-cooperativeness. A child with severe temporomandibular joint (TMJ) ankylosis presented with negligible mouth opening and required surgical correction under general anaesthesia. Successful intubation was performed with endotracheal tube size 5.5 mm using an adult 4.3 mm fiberoptic bronchoscope under inhalational as well as topical anaesthesia.
颅面畸形与下颌发育不全、下颌间隙减小伴软组织拥挤以及上颌发育不全有关。张口受限和下颌前突受限是这类患者气道困难的独立预测因素。由于小儿年龄组张口小且不配合,相对困难的问题在该年龄组中变得更加严重。一名患有严重颞下颌关节(TMJ)强直的儿童,张口极小,需要在全身麻醉下进行手术矫正。在吸入麻醉和表面麻醉下,使用成人4.3毫米纤维支气管镜,成功插入5.5毫米气管导管进行插管。
