Transoral Excision of a Lateral Pharyngeal Wall Mucocele in an 11-year-old: Case Report
摘要
Mucoceles are rarely found in lateral pharyngeal wall and may mimic more common cystic lesions in this region. We report an 11-year-old girl with a 6-month history of progressive snoring. Examination and nasoendoscopy revealed a right lateral pharyngeal submucosal mass narrowing the oropharyngeal isthmus. Contrast-enhanced CT showed a well-circumscribed 3.0 × 3.5 × 5.0 cm cystic lesion confined to the right lateral pharyngeal wall without parapharyngeal or parotid involvement. To completely remove the lesion, we used a transoral approach with endoscopic guidance and carried out a limited mucosal resection adjacent to the right torus tubarius. Histopathology showed a mucous retention cyst arising from minor salivary glands. Snoring disappeared postoperatively with no early recurrence. Mucocele should be considered in children presenting with lateral pharyngeal wall masses, and when the lesion is well circumscribed and accessible, endoscopically assisted transoral excision can provide definitive treatment with low morbidity.
