Objective: Isolated malleus fracture is a rare ossicular injury with less than 80 cases published in the literature. The aim of this paper is to present a series of 3 patients with isolated malleus handle fracture, to review the literature and to discuss clinical presentation, imaging findings and treatment options.
Methods: We retrospectively a case series of 3 patients with isolated malleus handle fracture managed at a tertiary referral otologic center.
Results: The three patients related the same history of digitally manipulating the external auditory canal, leading to a sudden hearing loss and feeling of aural fullness. Meticulous otomicroscopy revealed the broken malleus with excessive movement of the distal part of the malleus on pneumatic otoscopy. High-resolution CT scan with multiplanar reconstruction along the axis of the malleus confirmed the fractures and displacements. One patient was treated conservatively and two underwent ossiculoplasty.
Conclusion: Malleus handle fracture should be systematically suspected in case of hearing loss and aural fullness of sudden onset after digital manipulation of the external auditory canal.

An isolated fracture of the handle of the malleus is a rare entity in otorhinolaryngology and manifests clinically as acute-onset unilateral hearing loss. Several factors may cause this injury, including acute barotraumatic pressure changes or traumatic events. Various therapeutic approaches such as tympanoplasty, autologous graft, or application of bone cement are discussed.

Isolated malleus fractures are a rare occurrence with few reported cases in the literature. Symptoms include sudden otalgia, hearing loss, tinnitus and aural fullness. Work-up and diagnosis are based on a combination of thorough anamnesis and careful otoscopic evaluation or high-resolution computer tomography.

The temporal bone is a complex anatomical space that houses the middle ear and its ossicles, as well as the inner ear, which includes the vestibule, cochlea, and the semicircular canals. Henle's spine, also known as the suprameatal spine/spina suprameatica/ is found to guide the lateral wall of the mastoid antrum [J Res Med Dent Sci 8(7):420-422, Stat-Pearls Publishing, Treasure Island.
