Characteristics of polypoid lesions in patients undergoing microsurgery of the larynx

Abstract

Summary Introduction: Dysphonia is the main symptom of lesions that affect the vocal tract. Many of those lesions may require surgical treatment. Polyps are one of the most common forms of vocal cord lesions and the most prevalent indication for laryngeal microsurgery. There are different types of polyps, and their different characteristics can indicate different prognosis and treatments. Aim: To conduct a comparative study of polypoid lesions (angiomatous and gelatinous) in patients undergoing laryngeal microsurgery via an electronic protocol. Method: We prospectively evaluated 93 patients diagnosed with vocal fold polyps; the polyps were classified as angiomatous or gelatinous. Results: In total, 93 patients undergoing laryngeal microsurgery were diagnosed with vocal fold polyps. Of these, 63 (64.74%) had angiomatous and 30 (32.26%) gelatinous polyps. Most patients with angiomatous polyps were men; their polyps were frequently of medium size, positioned in the middle third of the vocal fold, and accompanied by minimal structural alterations (MSA). In contrast, the majority of patients with gelatinous polyps were women; their polyps were smaller, positioned in the middle and posterior third of the vocal fold, and were not accompanied by MSA. Both types of polyps were more frequently located on the right vocal fold. Conclusion: Angiomatous polyps were more frequently encountered than gelatinous polyps. In addition, correlations between polyp type and sex, polyp size, position, location, and the presence of MSA were observed. Different surgical techniques were used, but the postoperative results were similar and satisfactory after speech therapy.

Disfonia akibat polip pita suara

“…[4][5][6][7][8] Polip pita suara sering terjadi pada laki-laki dibandingkan perempuan dengan perbandingan 2:1 dan bisa ditemukan pada semua usia, biasanya pada usia dewasa antara umur 20-60 tahun. 5 Pembedahan merupakan pilihan terapi pada polip pita suara, bila terapi konservatif gagal.…”

“…[4][5][6][7][8] Saat inspirasi pita suara abduksi dan saat ekspirasi aduksi. Sebelum fonasi, pita suara abduksi secara cepat agar udara masuk ke saluran nafas (fase inspirasi sebelum fonasi) selanjutnya pita suara aduksi karena berkontraksinya otot krikoaritenoid lateral.…”

“…4,6,7 Faktor yang dapat menjadi pemicu terjadinya polip pita suara selain vocal abuse adalah merokok, alergi, infeksi kronis saluran nafas atas dan refluks laringofaringeal. 5,8 Diagnosis polip pita suara ditegakkan berdasarkan anamnesis, pemeriksaan telinga, hidung, dan tenggorok untuk mencari faktor risiko serta pemeriksaan laringoskopi dengan atau tanpa videostroboskopi.…”

“…[4][5][6][7] Pada anamnesis, pasien mengeluhkan suara serak yang dirasakan terus menerus dan lebih dirasakan saat penggunaan suara yang berlebihan. Keluhan kadang disertai rasa lelah bila berbicara.…”

“…Bisa berbentuk bulat, panjang, irreguler atau polipoid. 4,7 Predileksinya lebih dari 80% unilateral dan 20% bilateral atau multipel. Lesi ini biasanya terletak di sepertiga anterior atau sepertiga tengah.…”
