Dural repair through the transoral approach is difficult and CSF leak into the pharyngeal space
is a significant complication with high morbidity and mortality, making these key issues in the ultimate success of the surgery.
Infection in the parapharyngeal space can result from an original infection in the tonsils, pharynx, dentition, salivary glands, and nasal cavity that spread into the pharyngeal space
The results showed that growth of the thyroid (as indicated by its volume) is not accompanied by expansion of the primordium into the surrounding pharyngeal space (as indicated by its area).
The results of this study corroborate the preliminary findings of Hilfer (1973) that growth of the thyroid is accompanied by constraints on its lateral expansion into pharyngeal space and implicate microfilaments in stabilization of the peripheral cell ridge that defines the limits of the early thyroid.
Examination under general anesthesia revealed a left deep parapharyngeal abscess with spontaneous rupture in the pharyngeal space.
The lateral pharyngeal space is a transfer point for infections originating in the mandible, parotid gland, tonsils, and cellulitis of the sublingual and submaxillary spaces (Figure 3).
The lateral pharyngeal space is an inverted cone extending from the sphenoid bone to the hyoid bone.
In Patient 1, four potential space infections were considered: the submental, submandibular, sublingual, and lateral pharyngeal spaces.
When pharyngitis due to F necrophorum occurs, the physical proximity of the vessels in the lateral pharyngeal space
permits extension from the peritonsillar space to the internal jugular vein.
The parotid and par pharyngeal spaces
are secondary sites of spread, and these infections can subsequently spread to the submandibular spaces.
