Objectives:
Trauma to the oral tissues can be caused by fellatio. Few cases are reported in the literature.
Methods:
A case of oral palate lesions is presented and discussed.
Results:
The patient developed a large band of petechial haemorrhage extending across the soft palate following the practice of fellatio. The diagnosis was made through an interview with the patient, which disclosed a probable case for fellatio as the cause of the palatal spots. At the follow-up visit 14 days later, the lesions disappeared.
Conclusions:
Oral sex activity has increased over the last decades. The dental care professional should be aware that lesions of the palate may result from sexual behaviour. With this possibility in mind, those working in the area of head and neck medicine should consider fellatio as an addition to the differential aetiology of intraoral petechiae.
