IntroductionDEEP NECK SPACE INFECTIONS
antibiotics decreased the incidence and mortalitydeep neck space infections remain life threateningdelay in diagnosis/inadequate/inappropriate treatment complications (mediastinitis) mortality rates : 40%head and neck surgeon :cervical fascias & potential spaces understand the treatment & potential complications
-
Anatomy Of The Cervical Fascia Superficial cervical fascia Deep cervical fascia 1. Superficial layer 2. Middle layer - Muscular division - Visceral division 3. Deep layer - Prevertebral division - Alar division
-
Cervical Fascia
-
Retropharyngeal Space InfectionSource Nose Sinuses Adenoids Nasopharynx
Manifestations Acute URTI in infants & children Dysphagia & odynophagia Drooling & difficult to expell excretions Cervical rigidity Muffled voice Dyspnea Unilateral bulging of posterior pharyngeal wall Sepsis
-
Retropharyngeal Space Infection
-
Retropharyngeal Space InfectionTreatmentFastingI.V. antibioticsTracheotomyEmergent surgical drainage- intraoral drainage- external drainageComplicationsRupture of abcess w/ aspiration & pneumoniaMediastinitisAirway obstruction
-
Danger Space InfectionSourceRetropharyngeal spacePrevetebral spaceParapharyngeal spaceManifestationsSame as primary space infectionSevere sepsisTreatmentSame as for primary space infectionComplications Potential for rapid spread through the loose areolar tissue Inferior spread to the posterior mediastinum to the level of diafragma
-
Prevertebral Space InfectionManifestations Midline abcess Cold abcess posterior pharynx Slow spread of suppuration of this areaTreatmentNeedle aspiration w/ subsequent antituberculosis th/Stabilization of spineSource Vertebral bodies Penetrating injuries Tuberculosis of the spineComplicationsSpine instability progression of vetebral process
-
Visceral Vascular Space Infectionpotential space within the carotid sheathinfections remain relatively localized compact space contains little areolar connective tissue lymphatics contained within this space receive secondary drainage from most of the lymphatics of the head and neck Lincoln Highway of The Neck (Mosher) all three layers of the DCF contribute to the carotid sheath
-
Visceral Vascular Space InfectionSourceParapharyngeal spaceSubmandibular spaceVisceral space
ManifestationsPitting edema over SCMTorticollis
TreatmentExternal drainageI.V. antibioticsPossible ligation of IJV
ComplicationsSeptic shockCarotid artery erotionsEndocarditisCavernous sinus thrombosis
-
Pharingomaxillary Space Infection
-
Pharingomaxillary Space InfectionPrestyloid Compartement [anterior-muscular]FatLymph nodesInternal maxilarry arteryInferior alveolar, lingual,auriculotemporal nerves
Poststyloid Compartement [posterior-neurovascular]Carotid arteryInternal jugular veinSymphatetic chainIX, X, XI, XII nerves
-
Pharingomaxillary Space InfectionSource Tonsil Pharynx Teeth Temporal bone (petrous) Parotis gland Lymph nodes of nose & nasopharynxManifestations Medial displacement of lateral pharyngeal wall and tonsils Trismus Parotid edema Retromandibular neck fullness Dysphagia
-
Pharingomaxillary Space InfectionTreatment External drainageTracheotomyComplications Septic thrombosis of IJV Carotid artery erosions Cranial nerve involvement Mediastinitis

Submandibular Space InfectionSublingual space Sublingual gland Hypoglossal nerve Whartons ductsSubmaxillary space Central compartement Submental compartement Submaxillary compartementsubdivided by anterior bellies of digastric m.Contents Submandibular gland Lymph nodes
-
Submandibular Space InfectionSource Teeth Salivary glands Pharynx & tonsils SinusesManifestations Dysphagia Odynophagia
TreatmentUnderlying pathologyExternal drainage if it progress- sublingual- submandibula
Complications Ludwigs Angina
-
Masticator Space InfectionSourceMolar teeth
ManifestationsExtreme trismus Edema & tenderness over the posterior ramus of mandible
TreatmentExternal drainage
-
Temporal Space InfectionTemporalis m. :- superficial compartments- deep compartments ManifestationPain in this area Trismus TreatmentExternal drainage
-
Peritonsillar Space InfectionSourceTonsils & pharynx
Manifestations Dysphagia/odynophagia Drooling and hot potato voice Muffleed voice Reffered otalgia Trismus Displaced tonsil toward midline Deviated uvula
-
PERITONSILLAR ABSCESS
-
Peritonsillar Space InfectionTreatment Peroral drainage tonsilectomy
Complications Spread into pharyngomaxilary space through posterior pharyngeal wall
-
Anterior Visceral SpaceContents Pharynx Esophagus Larynx Trachea Thyroid gland
Source Tonsils Esophageal injury Blunt trauma w/ mucosal tear Acute thyroiditis Chest infection
