Introduction

The benign lesions of the voice box are widely diverse and bring forth general symptomatology known as dysphonia ( 1 ) . They include the functional lesions of psychobiologic reaction, palsies due to extralaryngeal disease, inflammatory multitudes due to vocal maltreatment, and true tumors of the intrinsic voice box. This list represents a profound challenge to the laryngologist, and the direction of these abnormalcies demands the usage of many surgical and nonsurgical techniques.Benign lesions of the voice box are of involvement and importance to the laryngologist, non merely because of the symptoms which they produce by intervention with the normal maps of the vocal mechanism or by obstructor of the respiratory piece of land but because of the necessity of separating them from malignant laryngeal lesions.The significance of benign lesions of the voice box besides lies in the importance of its map in speech production and the part of the voice to one & A ; acirc ; ˆ™s individuality ( 3 ) .The purpose of present survey was to transport out a prospective analysis of benign lesions of vocal cords treated in our institute over a period of 4 old ages.

Patients and Methods

In the present survey, 60 patients go toing the section of Oto-Rhinolaryngology, Head and Neck Surgery of King Hussein medical centre ( Amman- Jordan ) , between January 2006 and January 2010, showing with main ailment of gruffness of voice were taken up. Those found to hold seemingly benign laryngeal lesions were selected for the survey. All non operative instances and any patient screening grounds of malignance was non included.Patients were underwent a elaborate history taking with regard to the presenting symptoms and their continuance and thorough general physical scrutiny. After that each patient was subjected to indirect laryngescopy and or fiber-optic scrutiny. The fiber-optic laryngoscopy was conducted in the clinic, being preceded by a brief account of the process to still anxiousness.Patients so were subjected to direct microlaryngescopy with assistance of runing microscope in order to obtain a definite histopathological diagnosing.

The stuff obtained from the vocal cords for curative and diagnostic grounds. The laryngoscopies and remotion of tissue was performed by senior specializer in our section at King Hussein medical centre and all stuffs were examined by members of the section of pathology at our institute.Postoperative direction included complete voice remainder for three hebdomads followed by gradual recommencement of voice in order to restart the normal map of the vocal cords.After three hebdomads, when the healing appeared to be complete, a government of gradual speaking was started. The patient was instructed to stay soundless except for a specified period of clip mundane and so to bit by bit increase the frequence and continuance of these periods. This faculty was continued for two hebdomads after the surgery and so the patient was advised to be back to his normal regimen.

Along with this government, the patient was besides advised to avoid highly hot and cold nutrients, nutrients with strong flavorers, exposure to air pollutants, smoke, baccy, intoxicant and coughing and uncluttering the pharynx.Data sing sex and age of patients, anatomical site, business, post-operative followup and histopathological type of the lesions were analyzed.

Consequences

Demographic profile

Out of 60 instances, 43 were males and 17 females with a ratio of 2.5:1. Majority 50 % was in the age group of 26-35 old ages, the youngest patient was 5 old ages of age and the oldest 45 old ages of age ( Table I, II ) . The mean age in males ( 32.

51 & A ; Acirc ; ± 7.16 old ages ) was significantly higher as compared to that of females ( 27.61 & A ; Acirc ; ± 6.41 old ages ) ( p = 0.

03 ) .Hoarseness of voice was the chief presentation in 54 ( 90 % ) and stridor in 6 instances ( 10 % ) .Majority of the patients 73.

3 % presented within 1 year of the symptoms of gruffness and 15 % between 1-2 year of oncoming of gruffness ( Table III ) .The highest incidence was seen in homemakers 25 % followed by school instructors 21.7 % and pupils 18.3 % ( Table IV ) .

Type of lesion and site of beginning

Among assorted types of benign lesions, most of the instances in our survey group had vocal cord polyp found in 50 % of instances, vocal nodule in 21.

7 % , Reinke ‘s hydrops in 13.3 % , Vocal cyst in 6.7 % , multiple papillomatoseses in 5 % and Vocal cord villoma in 3.3 % of instances ( Table V ) .Sing the site of engagement, the commonest site of beginning was on both vocal cords in 38.3 % followed by 33.

3 % on the right vocal cords, and in the staying 28.3 % , the site of beginning was left vocal cord ( Table VI ) .The free border of vocal cord was the commonest site of beginning of these lesions in 70 % followed by anterior commissure 15 % , posterior commissure 10 % and 3 kids ( 5 % ) multiple papillomatous lesions were found in both vocal cords and extended up to the epiglottis ( Table VII ) .

Post operative forecast

In our survey, bulk of patients 90 % have wholly symptom free after surgery and 10 % have partial recovery of their symptoms. The return was in 4 instances of vocal cord villoma, 3 kids with multiple papillomatous lesions required several alterations utilizing CO2 optical maser ( Table VIII ) .

Discussion

The attention of the human voice has challenged the medical practician for centuries ( 5 ) .

Although seldom life threatening, voice jobs should non be underestimated as a medical upset. Besides impacting utile vocal communicating, gruffness may besides mean the presence of more serious medical conditions such as a malignance or airway via media ( 6, 7 ) . Hoarseness is the most common symptom of laryngeal disfunction regardless of its etiology.The precise cause of gruffness will merely be determined after scrutiny of the voice box either indirectly via a mirror, or straight via an endoscope. Before this, a careful history, peculiarly placing the continuance of symptoms, can supply of import information on likely etiology ( 8 ) .We carried out a prospective analysis of the benign lesions impacting the vocal cord. It & amp ; acirc ; ˆ™s cognize that each of the benign lesions of voice box has potentially different causes but there are common factors that contribute to their development.

Generally benign vocal lesions occur in response to injury but are besides known to hold multiple causes such as chronic vocal use/misuse.In our survey, Male predomination was observed, with Male: Female ratio of 2.5: 1, which is in conformity with the consequences of assorted other surveies ( 9, 10 ) . The bulk of patients ( 50 % ) were found to fall into the age group of 26-35 old ages at the clip of presentation with an age ranged from 5-45 old ages. It is known that persons in younger age group are more ambitious, active and utilize their vocal accomplishments maximally. Assorted surveies have reported a higher incidence of benign lesions of the voice box in the age groups between 20 and 60 old ages ( 3, 9, 10 ) .

A really interesting observation was that housewives formed 25 % of the survey group, the system of joint households and the big figure of kids in each household. It likely accounts for the common happening of glottic lesions like nodules and polyps in immature adult females. Majority of the patients in this series i.e. about 70 % belonged to businesss good known for inordinate vocal usage, such as instructors, imaum, histrion and medical forces etc.

These observations are similar to those of Baitha et Al. ( 11 ) .Duration of gruffness at presentation ranged from one hebdomad to three old ages with a average continuance of 2 months. Majority of the patients 73.3 % presented within 1 year of the symptoms of gruffness and 15 % between 1-2 year of oncoming of gruffness, similar determination was seen in other surveies ( 9, 10 ) .

The bulk of the patients were diagnosed to hold vocal cord polyps ( 50 % ) followed by vocal nodules ( 21.7 % ) , Reinke ‘s hydrops in 13.3 % , Vocal cyst in 6.7 % , multiple papillomatoseses in 5 % and Vocal cord villoma in 3.3 % of instances.

These lesions were diagnosed clinically and confirmed by histopathological scrutiny. There was strong correlativity between the clinical and histopathological findings among these patients. Previous surveies had shown different incidence rates of each of the benign vocal crease lesions.In a series of 106 lesions assessed during surgery, Mossallam et Al. ( 12 ) , found that polyps are the most common lesion followed by cyst, Reinke ‘s hydrops, nodules, granuloma ; benign neoplasias and pre-cancer lesions.

On the other manus, Bouchayer et Al. ( 13 ) presented the undermentioned findings in a series of 1,283 lesions of patients submitted to laryngeal microsurgery: nodules, 24 % ; cyst, 17 % ( 14 % cuticular, 3 % keeping ) ; vocal sulcus, 12 % ; polyp, 11 % ; pseudocyst, 6 % ; Reinke ‘s hydrops, 6 % ; nodular lesion, 5 % ; chronic laryngitis, 4 % ; postoperative cicatrix, 3 % ; anterior microweb, 3 % ; granuloma, 1 % ; laryngeal papillomatosis, & A ; lt ; 1 % ; other lesions, 7 % .With respects to the site of beginning, the free border of vocal cord was the commonest site of beginning of these lesions in 70 % . These findings are in conformity with the findings reported by Hegde et Al. and Baitha et Al. ( 3, 11 ) .All patients underwent direct microlaryngescopy and deletion of the cordal lesion followed by post-operative voice rectification therapy. Following this government, the present survey showed encouraging consequences as 93.

3 % of patients were normal without any return after individual operation.

Decision

Hoarseness of voice is a common manifestation of laryngeal disease. Vocal cord polyp and nodule are the most common encountered benign vocal cord lesions.Speech therapy following Micro laryngeal surgery signifiers an indispensable portion of intervention for benign vocal cord lesions as return can be avoided due to care of the primary lesion by turning away of forced or nerve-racking voice.
