About
The accepted recommendation after removal of vocal cord lesion is voice rest.This recommendation leads to great tension among the patients, loss of working days and need to practice speech therapy.The investigators hypothesize that voice rest after surgery does not affect the quality of the patient's voice. The investigators will divide the patients into 2 groups: the first group will be instructed for a postoperative voice rest and the second group will not. Later the investigators will compare the results and conclude whether voice rest had any significance.
Full description
The prevailing view among laryngologists is that voice rest after laryngeal surgery is important to ensure a good recovery of the epithelium and lamina propria layers of the vocal cord. Speaking immediately after surgery leads to the formation of an irregular collagen in large quantities of the vocal cords - namely the creation scar tissue. The scarred vocal cords leads to a decrease in its elasticity, which is reflected in poor speech quality. Although this theory, not many works were published in the literature proving the necessity for voice rest after vocal cord surgery.
Several studies have been recently published which claim that there is no need for vocal rest and stress the importance of a moderate voice effort straight after surgery. This need is based on the idea that early mobilization of tissue after surgery led to the creation of a healthy soft tissue architecture.
The investigators hypothesize that there is no role for vocal rest after surgery to remove benign lesions from the vocal cords.
Patients candidate for laryngeal surgery that include removal of a benign vocal cord lesion will be divided into two groups:
Patients instructed for the conventional post operative voice rest, namely absolute voice rest for a week and another week of relative voice rest (speaking is allowed for 20 minutes a day).
Patients instructed to speak freely without restrictions after the surgery. those are the study phases: * first visit- preoperative visit.
Lastly the patient is randomized (by block randomization) to determine to which group the patient belongs.
Patients belonging to the control group (standard post operative voice rest) receive a form where they annotate every day whether they kept on the instructed sound regime. This log will allow the investigators to track the compliance of the patients belonging to the voice rest group.
Second visit- 3 days post operative
Third visit- 14 days post operative
Same examination as the second visit are performed plus:
