生飛滋

「飛滋」的學名為復發性口瘡或復發性口腔潰瘍 (aphthous ulcer),是一種經常復發而又能自愈的口腔黏膜潰瘍,它通常出現於唇、面頰或齒齦等,邊界清晰而中間發紅及微腫,有時會造成灼痛感。

其實,飛滋是口腔黏膜表皮層受損傷後形成的傷口,成因未確定,但可能與多種因素有關,例如精神壓力、抵抗力差、身體受流感等病毒感染而削弱黏膜的抵抗力,再加上外來的刺激,如被食物刮損口腔、煙草中的尼古丁等,都會增加飛滋出現的機會。

要避免生飛滋,就要改善上述提過的誘因,多吃蔬果及多喝水,尤其要攝取足夠的維他命B2,以促進黏膜細胞健康。此外,亦要保持口腔清潔,減少細菌孳生,平日最好少吃燒烤、過熱或油炸等食物。

飛滋一般數日內可自愈,若情況持續兩周未愈甚至加劇,又或是經常長出又大又嚴重的飛滋,便可能是口腔黏膜病變或免疫系統出問題的徵狀,應盡快求醫檢查。

Aphthous ulcer is the most common type of nontraumatic ulcer. Incidence ranges from 10-20 % in the general population. The exact etiology is unknown but it has been linked to immunologic mechanism. Minor aphthous ulcers measure less than 1 cm while major ones are larger than 1 cm. The former typically lasts 1-2 weeks and resolves spontaneously, while the latter can persist up to months and heal by scarring.
Diagnosis is clinical and no microscopic feature is diagnostic of aphthous ulcer. Non-painful minor ulcers require no treatment. For painful and major ulcers, treatment ranges from dietary supplements, antibiotics, anti-inflammatory, oral mouth rinse, to chemical cautery with silver nitrate application.
