Evaluation of Surgical and Histopathologic Results of Patients Operated for Parotid Gland Tumor

Objectives: To investigate the patients with parotid tumors retrospectively and to evaluate the surgical procedure, histopathologic results, incidence, follow-up time and complications. Patients and Methods: The study included 56 patients (38 males, 18 females; mean age 52.7 years; range 7 to 86 years) who presented with a mass below or in front of the ear between January 2000 and May 2008. The data regarding patient age, sex, surgical procedure, postoperative histopathologic results and follow-up time were recorded. Results: One of the male patients underwent operation twice because of the bilateral parotid mass. According to the postoperative histopathologic results, 37 of the cases were benign (64.9%), and 20 of them were malign (35.1%). Pleomorphic adenoma (13 patients) and Whartin tumor (13 patients) incidence were similar. Partial superficial parotidectomy, superficial parotidectomy, and total parotidectomy were performed. In addition, some of the patients underwent neck dissection. The most frequent complication was transient facial nerve paresis. Conclusion: For the management of benign parotid gland tumors, superficial or partial superficial parotidectomy is a sufficient surgery. For malign tumors, superficial or total parotidectomy; in cases with neck masses, neck dissection; and in cases involving the facial nerve, facial nerve resection and reconstruction should be performed. According to the type of tumor, postoperative radiation therapy and chemotherapy should be performed as well. Turkish Baslik: Parotis Bezi Tumoru Nedeniyle Ameliyat Edilen Olgularin Cerrahi ve Histopatolojik Sonuclarinin Degerlendirilmesi Anahtar Kelimeler: Parotis neoplazmlari; biyopsi, ince igne; patoloji; cerrahi girisim; boyun diseksiyonu Amac: Parotis tumoru ile klinigimize basvuran olgulari retrospektif olarak incelemek; uygulanan cerrahi islemleri, histopatolojik sonuclari, gorulme oranlarini, takip surelerini ve komplikasyonlari degerlendirmek. Hastalar ve Yontemler: Ocak 2000 ile Mayis 2008 tarihleri arasinda kulak onunde ve/veya kulak altinda sislik sikayeti ile basvuran 56 hasta (38 erkek, 18 kadin; ort. yas 52.7; dagilim 7-86) calismaya dahil edildi. Hastalarin yasi, cinsiyeti, ameliyat sekli, ameliyat sonrasi histopatolojik sonuclari ve takip sureleri kaydedildi. Bulgular: Bir erkek olgu iki tarafli lezyon nedeniyle iki kez ameliyat oldu. Ameliyat sonrasi histopatoloji sonuclarina gore olgularin 37a#39;si selim (%64.9), 20a#39;si habis (%35.1) idi. Selim tumor olarak pleomorfik adenom (13 olgu) ve Whartin tumoru (13 olgu) esit sayida saptandi. Cerrahi yontem olarak parsiyel yuzeyel parotidektomi, yuzeyel parotidektomi veya total parotidektomi uygulandi. Bu tedaviye ek olarak bazi olgularda boyun diseksiyonu uygulandi. En sik gorulen komplikasyon gecici fasyal sinir parezisi idi. Sonuc: Parotis bezi tumorlerinin tedavisinde selim olanlarda yuzeyel veya parsiyel yuzeyel parotidektomi yeterli bir tedavidir. Habis tumorlerde ise yuzeyel, total parotidektomi uygulanmali, boyun kitlesi olan olgulara boyun diseksiyonu, fasyal sinir tutulu olgularda ise fasyal sinir dallarinin rezeksiyonlari ve onarimlari yapilmalidir. Tumor tipine gore ameliyat sonrasi radyoterapi ve kemoterapi tedaviye eklenmelidir.
