Hello Thank you for trusting HCM Dear where is the hole?? Is it on the tonsil or posterior pharygeal wall, soft palate or in the hard palate? Some times streptococcus throat infection can gives rise to tonscillar hole, some time defect in soft hard palate may cause hole. Granulomatous lesions may cause this appearance. Ulcers in the oral cavity by viral, acid reflux may gives this appearance. Please consult your Ent surgeon he will examine and treat you accordingly.
