The term otorrhoea originates from the Greek words otos, meaning "ear," and rhein, meaning "discharge." Similarly, the Unani term Sayal?n al-Udhunis derived from the Arabic words Sailan, meaning "discharge," and Udhun, meaning "ear." Renowned Unani scholars have defined otorrhoea as Sayal?n al-Udhun, describing it as a condition characterized by a burning sensation in the external auditory canal, accompanied by continuous ear discharge. Otorrhea, the discharge from the ear, is a common symptom associated with various ear disorders such as otitis media, otitis externa, and tympanic membrane perforations. This condition is particularly common in children and individuals with a wet temperament (Miz?jRa?b).According to Unani principles, otorrhoea often occurs in individuals with an excess of bodily fluids (Akhl??) and a phlegmatic temperament (Balgham? al-Miz?j). The symptoms include Waja‘al-Udhun(ear pain orotalgia), Izdiyad-e-Hararat (increased body heat), a sense of fullness in the ear, stabbing pain in the temples, and pressure buildup in the ear. In Unani medicine, treatment for otorrhoea includes systemic and local approaches. Systemic remedies often involve the use of blood purifiers (Mu?aff?-i-Dam), anti-inflammatory agents (Mu?allil), analgesics (Musakkin), and antimicrobial agents (D?fi‘-i-Ta‘affun). Locally, treatments include drying agents (Mujaffif) applied through methods such as fumigation (Tadkh?n) and insufflation (Naf?kh). This review explores the understanding, diagnosis, and treatment approaches to otorrhea from the perspectives of Unani and modern medicine.
