Bacterial Colonization of the Condyle in Patients with Advanced Mandibular Osteoradionecrosis: Analysis of Hemimandibulectomy Specimens

Table 2

Extents of macroscopic bone destruction and bacterial colonization within the condyle in hemimandibulectomy specimens.

Patient	Macroscopic bone destruction							Bacterial colonization
	Mandibular body (anterior to bone exposure )		Bone exposure area		Ramus (posterior to bone exposure)		Condyle	Condyle
1	−	−	Crest side	+	Around MC^a	++	+	+
					Near inferior margin	++
2	−	−	Crest side	+	Around MC^a	+	−	+
					Near inferior margin	++
3	Near extraction socket	+	Crest side	++	Around MC^a	++	++	++
					Near inferior margin	+
4	−	−	Near inferior margin	++	Around MC^a	++	−	−
					Near inferior margin	+

Abbreviations: ^aMC, mandibular canal. The most anterior bone sections are resected margins, so those are excluded for evaluation. The extents of macroscopic bone destruction and bacterial colonization are each classified into four grades: −, none; ±, little; +, moderate; ++, severe.
