“…In humans, they are indeed rarely fractured. ( 21 , 22 ) Occasionally the ossicles can be fractured without damage to the skull, for instance, if a sneeze is prevented; one unfortunate woman fractured a stapes during the effort of childbirth. ( 23 ) For auditory reasons, a desirable feature of the auditory ossicles is to be as stiff as possible with minimum mass.…”

Because bone is obviously in some way adapted to the loads falling on it and because fracture is usually the failure of mechanical competence of main clinical importance, it is often thought that bones are adapted to resist fracture. In this perspective, I consider that this may not be the case. Bones may be designed to be very stiff, and therefore highly mineralized, and therefore brittle; they may be adapted to normal loads, but not to the characteristic loads occurring in falls, or may be very poorly designed to stop cracks traveling once they have started. Bones may also potentially fail in completely contrasting modes, and therefore their design has to be a compromise that does not resist either mode completely successfully. The greatly differing fracture incidences in different bones seen in pre-senile adults suggest that safety factors have been adapted, over evolutionary time, to produce the best compromise for a host of different design constraints.

“…3,4 However, the incidence of internal stapediovestibular dislocation without a stapes fracture is rare. Over the years, cases of stapediovestibular dislocation with intact stapes have been reported from all over the world, [5][6][7][8][9][10][11][12][13][14] as summarized in Table 1.…”

“…5 If the patient still has some residual hearing, auditory chain reconstruction and tympanoplasty are usually performed. [6][7][8] Several methods and materials of reconstruction can be employed, such as the temporal myofascial flap or perichondrium, artificial auditory ostium, and autogenous columellar cartilage. 10…”

Stapediovestibular dislocation is a rare disorder as a result of traumatic injury to the structures in the middle ear. We described a case of a 60-year-old female with stapediovestibular dislocation with associated perilymph fistula. She presented with symptoms including hearing loss, vertigo, and tinnitus after a penetrating injury by an ear pick. After 4 months of conservative management, her symptoms failed to improve. Therefore, she underwent surgery which resolved completely her vestibular symptoms and her hearing loss had partially improved. The restoration of the stapes to its normal anatomical position coupled with ossiculoplasty and closure of the tympanic membrane are effective in patients with stapediovestibular dislocation.
