Abstract:
Vocal process granulomas are benign lesions involved in the healing of posterior glottis injuries. Here, we report the results of our conservative treatment of vocal process granulomas. Fifty-three patients with 54 occurrences of granulomas between 1998 and 2007 were enrolled. All patients were observed without surgical excision or specific medications and regularly monitored with telescopic examinations until the granulomas disappeared. Data on age, sex, clinical presentation, prior history of intubation or gastroesophageal reflux, telescopic findings, management and clinical course were reviewed. There were 41 males and 12 females. The mean ages of granuloma occurrence were 48.1 years in men and 41.6 years in women (p=0.16). Symptoms included hoarseness in 42 patients, cough in 13 patients, lumping sensation in the throat in 15 patients and sore throat in 14 patients. Ten occurrences were stable during the follow-up period, and the other 44 (81%) achieved complete remission (mean period of 30.6 weeks). The remission patterns included progression and remission in 6 occurrences, slow remission in 22 and rapid remission in 16. The remission rate of granulomas was not significantly related to age (p=0.71), sex (p=0.43), prior intubation (p=0.71), acid reflux (p=0.47), unilateral/bilateral lesions (p=1.00) or granuloma size (p=0.46). The remission time was significantly shorter in patients with prior intubation (p=0.04), but not significantly associated with age (p=0.89), sex (p=0.87), acid reflux (p=0.91), unilateral/bilateral lesions (p=0.26) or granuloma size (p=0.96). Long-term observation has demonstrated that vocal process granulomas can be cured at high remission rates without implementing specific treatments.

Larynx
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
