Somatostatin immunoreactivity in quail pterygopalatine ganglion

Eight dogs underwent denervation of the nasal mucosa by bilateral surgical interruption of the caudal nasal nerve, major palatine nerves, nerve branches traversing the pterygopalatine ganglion, and ethmoid nerve. Determinations of pulmonary resistance and compliance immediately before denervation and 1 hour, 24 hours, and 7 days after denervation did not demonstrate a tonic nasal influence on pulmonary mechanics. Changes within the range of normal did occur in the immediate period after denervation. Because pulmonary resistance and compliance approached control values by the seventh day after denervation, these variations are probably the result of atelectasis and pooling of mucus within the bronchi, secondary to prolonged general anesthesia. Thus, pulmonary mechanics probably are not significantly altered after denervation of the nasal mucosa.

Systemic Side Effects

Regional anesthesia is widely used in ophthalmology both as an independent method and in combination. Retrobulbar anesthesia has risks of complications and is undesirable in the surgical treatment of choroidal melanoma due to the risk of metastasis of tumor cells when it is performed. Therefore, it is necessary to search for alternative methods of regional blockades in order to create prolonged anesthesia. Purpose. To develop and evaluate the clinical efficacy of pterygopalatine blockade as a component of combined method of anesthesia for evisceration or enucleation of the eyeball. Methods. A comparative analysis of the effectiveness of intraoperative anesthesia and the course of postoperative period was carried out in patients of two clinical groups formed depending on the method of anesthesia. Results. Intraoperative monitoring of hemodynamics in the groups did not differ. The nature of pain in the patients of the compared groups in the postoperative period had significant differences in presence and intensity of pain on the scale of verbal sensations. Discussion. Use of pterygopalatine blockade with levobupivacaine in combination with dexamethasone as an adjuvant allows getting a prolonged analgesic, anti-inflammatory and decongestant effect. This makes it possible to avoid the use of opioid analgesics in the early postoperative period, that is, to avoid such systemic side effects as nausea, dizziness, and in rare cases vomiting, which generally improves the quality of the postoperative period. Conclusions. Use of pterygopalatine ganglion blockade with local prolonged-acting anesthetic levobupivacaine and dexamethasone as an adjuvant based on inhaled anesthesia with sevoflurane provides safe and effective anesthesia in patients with evisceration or enucleation of the eyeball, both in the intra- and postoperative period. Key words: enucleation; evisceration; pterygopalatine blockade; dexamethasone.

Pterygopalatine Ganglion

Purpose. To study the anatomy of the pterygopalatine fossa (PPF) using ultrahigh-resolution magnetic resonance imaging.Methods. A human cadaveric tissue block containing the pterygopalatine fossa was examined on a clinical 7-Tesla magnetic resonance imaging system. Subsequently, cryosections of the tissue block were created in a coronal plane. The cryosections were photographed and collected on adhesive tape. The on-tape sections were stained for Mallory-Cason, in order to detail the anatomic structures within the fossa. Magnetic resonance images were compared with surface photos of the tissue block and on-tape sections.Results. High-resolution magnetic resonance images demonstrated the common macroscopic structures in the PPF. Smaller structures, best viewed at the level of the operation microscope, which have previously been obscured on magnetic resonance imaging, could be depicted. Some of the orbital pterygopalatine ganglion branches and the pharyngeal nerve were clearly viewed.Conclusions. In our experience with one human cadaver specimen, magnetic resonance imaging at 7 Tesla seems effective in depicting pterygopalatine fossa anatomy and provides previously unseen details through its demonstration of the pharyngeal nerve and the orbital pterygopalatine ganglion branches. The true viability of depicting the pterygopalatine fossa with ultrahigh-resolution MR will depend on confirmation of our results in larger studies.
