Plemorphic adenoma of the infratemporal space: a new case report

Giant Pleomorphic Adenoma of Infratemporal Fossa: A Rare Case Report

Of all the head and neck tumors, salivary gland tumors account to 3%. Pleomorphic adenomas are one of the most common benign tumors arising from major salivary glands, although it could also develop from minor salivary glands situated at accessory sites like nasal cavity, pharynx, parapharyngeal space, lacrimal glands etc. Tumors of infratemporal fossa are quite unusual, mainly because of its hidden location in retromaxillary region. We report an unusual case of 65 years old male presenting with complaint of progressive left cheek swelling for 4 years. FNAC revealed pleomorphic adenoma of minor salivary gland tumor. Intraoperatively a giant lobulated tumor was seen occupying almost whole space of infratemporal fossa, which was removed in-toto via open approach. Patient was kept on regular follow up with no evidence of recurrence reported till date.

An unusual presentation of pleomorphic adenoma in a patient with thalassemia: A case report

•

Pleomorphic adenoma benign mixed tumor is a benign heterogeneous tumor.

•

Infratemporal fossa infarcted neoplasms may present clinically as an abscess.

•

The combination of CT scan and MRI might be a helpful diagnostic tool.

•

Treatment of Infratemporal fossa infarcted neoplasms tumors is surgical.

•

Transcervical approach allows excellent control of the tumor and neurovascular elements.

We report the first case of spontaneous infarction occurring in pleomorphic adenoma located in infratemporal fossa mimicking parapharyngeal abscess, including clinical presentation, workups, and surgical approach. The final diagnosis was confirmed on a histological basis. The combination of CT scan and MRI might be helpful in distinguishing neoplasia from abscess collection in this area. Surgical intervention is the treatment of choice.

Use of submandibular gland flap for repairing defects after tumor resection in the infratemporal region

OBJECTIVE

To investigate the application of submandibular gland flap with facial artery and vein pedicle, for repairing defects following tumor resection in the infratemporal region.

PATIENTS AND METHODS

Fifteen patients, including eight males and seven females ranging in age from 21 to 73 years, underwent surgical resection of tumors in the infratemporal region. Tumors were exposed using the submandibular incision approach and completely resected after pulling and rotating the mandible laterally. Mandibular osteotomy was performed for larger tumors or those that were not completely exposed. After tumor resection, the submandibular gland flap was used to fill up the residual defect following tumor resection.

RESULTS

The incisions healed well without exudation or infection (primary healing) postoperatively in all the patients. Long-term follow-up showed no tumor recurrence in all cases. Seven of the patients who underwent mandibular ramus osteotomy had numbness of the lower lip due to inferior alveolar nerve injury. No other complications were observed postoperatively.

CONCLUSION

The submandibular gland flap with facial artery and vein pedicle is a reliable, effective, and easy approach for repairing the defects caused by tumor resection in the infratemporal region, and has great potential for application in the clinical setting.
