RECENT FINDINGS: Modifications of the EMM technique in the last two decades, aimed at mucosal preservation of the inferior turbinate, nasolacrimal duct, and medial maxillary wall have been successful in addressing a multitude of diseases. There are also evidences to support adjunct procedures/methods to improve access, healing, and to address associated dysfunction such as impaired mucociliary clearance. Tailored approaches have shown favourable outcomes with a low rate of adverse effects.
SUMMARY: The EMM is appropriate for selected indications, in particular lesions causing medial wall destruction or extensive tumour involving the anterior wall or the prelacrimal recess. As for other maxillary sinus diseases including those identified to a limited site, a modified EMM is a reasonable consideration. The choice is appropriate provided instrument access, visualization, the ability for complete resection, postoperative care, and the requirement for surveillance is not compromised. A tailored approach with or without adjunct procedures is recommended.
CASE REPORT: We presented a case of left maxillary mucopyocele in a 58-year-old man that developed after radiotherapy for nasopharyngeal carcinoma. Computed tomography scan showed opacification of the left maxillary sinus expanding through the medial wall of the antrum with thinning and destruction of the adjacent structures. Endoscopic marsupialization of the lesion and left partial maxillectomy were performed. The cystic mass had yellowish thick mucopurulent fluid that was completely drained.
CONCLUSIONS: A few cases of sphenoid sinus mucocele as a late complication of radiation therapy have been reported. Maxillary mucocele and mucopyocele can be considered as one of the late complications of radiotherapy to head and neck as a result of occlusion of sinus ostia by scarred mucosa.
CASE REPORT: A case of an aspergillosis localized in the infratemporal fossa and another case of tuberculosis of the infratemporal fossa originating from the maxillary sinus, is described. The first patient was immunocompromised and showed symptoms of facial numbness; whereas the other was an immunocompetent man who complained of trigeminal neuralgia type pain. It was difficult to differentiate between infection and tumour despite the utilization of computed tomography scans and magnetic resonance imaging.
CONCLUSION: These cases illustrate the need for a high index of suspicion; in addition to endoscopic confirmation and histopathology to establish precise diagnosis and early intervention.
