H83.13
Labyrinthine fistula, bilateral
Clinical Classification Guidelines
Medical Intelligence & Overview
A bilateral labyrinthine fistula is a rare condition involving an abnormal opening between the inner ear's labyrinth and the middle ear or external ear canal on both sides. The labyrinth is critical for hearing and balance. When a fistula develops, it can disrupt these functions, leading to various symptoms and challenges. Recognizing this condition is important for proper diagnosis and management, which typically involves specialists in otology and audiology.
Causes & Symptoms
Clinical Causes: Chronic otitis media (persistent middle ear infections) that weaken ear structures Trauma or injury to the ear, such as skull fractures or direct blows Previous ear surgeries that may inadvertently cause a fistula Congenital abnormalities present at birth Erosive diseases affecting the ear structures
Key Symptoms: Dizziness or vertigo, especially triggered by changes in pressure or head movements Hearing loss, which may be partial or complete Tinnitus or ringing in the ears A feeling of fullness or pressure in the ears imbalance or difficulty maintaining balance Sensitivity to loud sounds or auditory distortions
Diagnostic & Treatment
Diagnosis Path: Diagnosing a bilateral labyrinthine fistula involves a combination of clinical examination and specialized tests. Audiograms assess hearing function, while vestibular testing evaluates balance issues. Imaging studies, particularly high-resolution computed tomography (CT) scans of the temporal bones, help visualize the inner ear structures and identify any abnormal openings or defects. An ENT specialist will interpret these results to confirm the diagnosis and plan treatment.
Treatment Protocols: Surgical repair of the fistula to close the abnormal opening and strengthen ear structures Medications to control dizziness or vertigo, such as vestibular suppressants Hearing rehabilitation through hearing aids or cochlear implants if necessary Physical therapy focused on balance improvement Regular monitoring and follow-up to assess recovery and prevent complications
