Correct answer: A — Oro-antral communication
The correct answer is A. An oro-antral communication is a recognised complication of upper third molar extraction because the roots may be close to the maxillary sinus. UK consent standards require discussion of risks relevant to the proposed treatment and to the individual patient; where sinus proximity is evident clinically or radiographically, this risk is particularly material. Inferior alveolar nerve injury and lingual nerve injury are characteristic risks of mandibular, not maxillary, third molar surgery. Mandibular fracture is a rare complication of difficult lower-molar extraction and is not a procedure-specific risk here. Cavernous sinus thrombosis is a remote consequence of spreading infection, not a routine direct complication requiring specific discussion for uncomplicated upper-third-molar extraction.
