Type a botulinum toxin in the management of spontaneous salivary otorrhea: a case report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSpontaneous salivary otorrhea is a rare presentation only previously documented twice in literature where parotid salivary secretions are found in the external auditory canal. Conventional treatment of spontaneous parotid salivary fistulas includes surgical management with interposed grafts, fistula tract ablation, and possible superficial parotidectomy. Associated risks include facial nerve injury, Frey syndrome and facial scarring. Here we report the first case of spontaneous salivary otorrhea conservatively managed with a type A botulinum toxin (BTA) injection. CASE PRESENTATION: A 17-year-old female presented with a 5-month history of left sided otorrhea and transient left facial swelling associated with gustatory stimulation. The otorrhea fluid tested positive for salivary amylase and negative for beta 2 transferrin. Fifty units of BTA were injected into the left parotid gland under ultrasound guidance. Cessation of symptoms was achieved 3 weeks after intervention. The patient remains symptom-free at the 2 year follow up.
conclusionBTA injection was well tolerated under ultrasound guidance and has led to long-term resolution of the patient's symptoms. BTA injection appears to be a safe and effective way to conservatively manage this rare presentation of spontaneous salivary otorrhea.
