PLEOMORPHIC ADENOMA OF SALIVARY GLANDS: AN EXPERIENCE AT TUTH
Abstract
Objective: .
To evaluate the frequency of distribution and surgical management of pleomorphic adenoma (PA) of salivary glands at Tribhuvan University Teaching Hospital (TUTH).
Methods:
It is a retrospective study. The medical records of patients diagnosed as PA and who underwent surgery in TUTH between September 2004 to January 2009 were analyzed.
Results:
Thirty two patients, 15 males and 17 females with age ranging from 15 to 85 years were analyzed. PA affected the parotid gland in 25 patients, the submandibular gland in 4 patients, the soft palate in 2 patients and upper lip in 1 patient. Amongst the PA of the parotid gland, the tumor was found to arise from the superficial lobe in 20 patients, deep lobe in 4 and both superficial and deep lobe in 1 patient. Eighteen patients underwent superficial parotidectomy, 4 underwent wide excision while 3 underwent total conservative parotidectomy. In the immediate post-operative period, 6 patients had facial palsy, 15 had marginal mandibular nerve paresis, 3 had flap discoloration and 1 patient complained of numbness of the ear lobule. All 4 patients with PA of the submandibular gland underwent excision of the gland. Amongst them, 3 developed marginal mandibular nerve paresis while 1 developed hematoma. The 2 patients with PA of soft palate underwent wide excision of the tumor. One patient developed palatal fistula. There was only one patient with PA of the upper lip which was excised in toto with no post-operative complication.
Conclusion:
PA commonly involved the parotid gland, the tumor arising mostly from the superficial lobe. Most patients were treated with superficial parotidectomy while few patients underwent total conservative parotidectomy and wide excision. PA of the submandibular gland required excision of the gland with the tumour and PA of minor salivary glands required wide excision.
