Bumps in the ear canal without pain or itching may be related to papilloma of the external auditory canal, exophytic osteoma of the external auditory canal, cholesteatoma of the external auditory canal and other diseases, which need to be selected according to the cause and extent of the disease, general treatment, drug treatment and surgical treatment.
1. Papilloma of external auditory canal: this disease is caused by human papilloma virus infection after trauma and decreased resistance of external auditory canal. Those with small tumors can be asymptomatic and painless. The tumor can be completely excised, and then silver nitrate and interferon can be used to coat the wound. Electrocautery and laser can also be used to cauterize the root of the tumor.
2. Ectodermal osteoma of external auditory canal: it occurs after local trauma, inflammation and cold water stimulation, and it is an abnormal proliferation of the bone of external auditory canal and produces nodules. When the swelling is small, it can be asymptomatic and only found during examination. It can be removed with the help of high-frequency drill or bone chisel and external auditory canal plasty.
3. Cholesteatoma of the external auditory canal: It is mostly secondary to the accumulation of keratinized epithelial cells in the external auditory canal after inflammatory reaction. If the cholesteatoma is small and not infected, it may appear as a lump in the ear canal without pain or itching. The cholesteatoma can be removed with the help of specialized tools to separate the cholesteatoma from the bony wall of the external auditory canal, either as a whole or in sections.
When you find a lump in the ear canal that doesn’t hurt or itch, you can actively consult a doctor for a systematic examination, make a clear diagnosis, and follow the doctor’s instructions for standardized treatment.
