Most common site for spread dental infection break out alveolar bone

Path of least resistance—>
thickness bone
Site of infection
Relationship of bone perforation to muscles attachment

Q

Submassetetic masseteric space

A

Location—> Between masseter and ramus
Infection—> trismus ( frecuencia )
Dental source—> impacted 3third molar

17
Q

Pterygomandibular space

A

Between —> medial pterygoid md trismus

Contains —> sphenomandibular ligaments
Inferior alveolar nerve vessels
Lingual nerve
Chorda tympani

Dental source —> Md third molar contaminated or needle contaminated

HIGH RISk —> proximity lateral pharyngeal space

18
Q

Pterygomandibular space

A

Between —> medial pterygoid md trismus

Contains —> sphenomandibular ligaments
Inferior alveolar nerve vessels
Lingual nerve
Chorda tympani

Dental source —> Md third molar contaminated or needle contaminated

HIGH RISk —> proximity lateral pharyngeal space

19
Q

Parapharyngeal lateral pharyngeal space

A

Between—> masticator space ant
Retropharyngeal space post

Dental source—> Md third molar

Infection —> swelling tonsil
Lateral pharyngeal wall
Very painful swallowing

VERY HIGH RISK proximity and continuity with retropharyngeal space

20
Q

Retropharyngeal space

A

Between —> buccopharyngeal fascia
Alar fascia
Spans base of skull to mediastinum

VERY HIGH RISK highway of infection spread from the head

21
Q

Danger space

A

Between—> alar fascia, prevertebral fascia

Spans—> base of the skull to post mediastinum and diaphragm

EXTREMELY HIGH RISK highway of infection spread

22
Q

Parotid space

A

Infection—> medial bulge lateral pharyngeal wall, pain and trismus

Not involved dental infections

Caused parotitis, sialothiasis, sjorgren’s syndrome

23
Q

Treatment in parotid space

A

Extraction or pulpectomy ( odontogenic origin)
Incision and drainage —> decrease bacterial load increase blood flow to site ( large swelling)
Antibiotic coverage (diffuse swelling, fascial spaces are involved if there’s systemic manifestations fever, tachycardia lymphadenopathy

24
Q

Fascia

A

Thin casing of connective tissue beneath the skin sorround and holds every organ, nerve and muscle in place

Superficial-> loose conective tissue under the dermis
Deep -> dense conective tissue that sorrounds
Visceral -> suspends organs within their cavities
