Middle ear ossicular disorders can cause conductive hearing loss. Ossicular disorders include fibrous unions of the incus; fixation from otosclerosis, cholesteatomas and congenital malformations. Here we reported two rare cases of middle ear ossicular disorders caused by congenital malformations. Case 1 was a 16-year-old boy complained about hearing loss of right ear for 1year. The radiology revealed as the right incudostapedial joint malformation. During the surgery ,we found the head of stapes abnormal without the anterior and posterior arch, but normal foot plate movement. We implanted a TORP artificial ossicle, and the patients enjoyed much better hearing post-operatively. Case 2 was a 23-year-old girl suffering from hearing loss of the left ear for two years. The temporal CT scan showed that the long foot of incus in the left ear was short, the incus and stapes angle was enlarged, considering possible ossicle deformity. We explored the the tympanic cavity and observed that the long foot of the incus was shifted forward, and the stapes was fixed. We removed partial foot plate, and insert a piston artificial ossicle. After the surgery, the patients achieved a satisfactory hearing improvement without other discomfort. Well, the ossicular chain includes malleus, incus, and stapes. Different ossicular disorders require different types of artificial ossicles for the reconstruction. It is desirable that scientists will create a new deformable artificial ossicle suitable to any type of ossicular disorders.
