A positive Rinne test result is NORMAL, where the air conduction is heard better than the bone conduction. This is unusual for a medical sign, where the positive sign is usually pathological. This can lead to some confusion. Normal hearing will have a positive Rinne test result in both ears and Weber test will be central (Figures 2.9–2.11).
Otosclerosis

Otoscopy is usually normal; however, some patients may have dilated arteries on the medial wall of the middle ear due to increased vascularity of the otosclerotic foci. This gives the middle ear seen through the drum a reddish appearance and is known as a flamingo flush or Schwartze's sign. The patients have a conductive hearing loss usually with a negative (bone conduction better than air conduction) Rinne test. Pure-tone audiometry will confirm the conductive hearing loss, which is usually worse at lower frequencies. The bone conduction is frequently reduced at 2 kHz (Carhart's notch), possibly due to the ossicular chain being fixed. If the cochlea is involved patients may have a mixed hearing loss. Pure sensory hearing loss from cochlear otosclerosis with no involvement of the ossicular chain is rare. In cases where there is sensory hearing loss speech audiometry can be useful. If the maximum speech reception score is less than 60% and the other ear is normal, then the benefit of surgery may be limited. Tympanometry may show reduced compliance due to fixation of the ossicular chain but is typically normal. Stapedial reflexes are normally reduced or absent.

Weber and Rinne hearing tests are screening tests used to help identify conductive versus sensorineural hearing loss in patients. With our patient, Weber testing lateralised to the right ear, and Rinne testing revealed normal sound perception in the right ear (air conduction greater than bone conduction; positive Rinne test) and revealed reduced sound perception in the left ear but with air conduction greater than bone conduction, suggesting sensorineural hearing loss of the left ear. The patient was adamant that her hearing had diminished on the left side in the previous two months, and a subsequent audiological consultation also suggested sensorineural hearing loss of the left ear.
Oval window atresia with inferiorly located facial nerve: Successfully use of alternative fenestration site of cochleostomy for ossicular chain reconstruction

A physical workup revealed no craniofacial malformation, normal pinna, external auditory canal and tympanic membrane. Rinne test was negative on the right side. Weber test showed lateralization towards to the right. The tympanogram was the Ad type. Stapes reflex was absent on the right side. Tubomanometry test score was 10, indicating normal eustachian tube function. Audiogram revealed mean 50 dB air-bone gap (ABG). Upon high-resolution CT, the oval window was atresic, and the facial nerve was overlaying the vestibula with the stapes absent.

In Denmark, the first choice of treatment for OS-related hearing impairment is a hearing aid. However, as hearing loss may progress, some patients experience increasingly audibly unsatisfying results or have other reasons to opt out of hearing aids [11]. Stapes surgery, usually stapedotomy, is an alternative offer in case of conductive hearing loss with an air-bone gap of at least 20 dB and a negative Rinne test [11,12].
