Nasopharyngeal teratoma involving the temporal bone.
Teratoma is the most common nasopharyngeal tumor in neonates. The tumor is usually limited to the oropharynx and is manifest by stridor and respiratory distress. Complete excision affects a cure. An unusual case of nasopharyngeal teratoma extending into the temporal bone, causing facial paralysis and conductive hearing loss, in addition to stridor, is presented. Stridor was relieved by transoral partial excision shortly after birth. Complete removal of the tumor by way of a subtemporal and infratemporal fossa approach was performed at 14 months of age. The defect was filled with a rectus abdominis muscle graft with microvascular anastomoses. The facial nerve was reconstructed secondarily with a sural nerve graft. The patient has no recurrence tumor and has good facial function at 30 months. This case demonstrates the first known case of facial paralysis due to nasopharyngeal teratoma. The surgical approach for tumor removal: lateral infratemporal fossa dissection, and the method of reconstruction: free rectus abdominis muscle flap with microvascular anastomoses, had so far not been described in a patient this young.
