Liposarcoma is the second most common sarcoma of the adult life, next to malignant fibrous histiocytoma. Liposarcoma in larynx and hypopharynx is extremely rare. The symptoms are variable, but it has a clinical importance because they can cause unpredictable airway obstruction, particularly during the induction of general anesthesia. A 79-year-old male patient was referred to our department for mild airway obstruction and throat discomfort. Neck CT scan showed a mass within both postcricoid area and pyriform sinus. The mass was removed via laryngeal microsurgery. In this article, we report a case of liposarcoma of the posterior wall of hypopharynx with a review of the related literature.

As public awareness of the various warning signs of malignancy increases, so does the concern evoked by the self identified finding of mass in the head and neck area. Not all the palpable masses are always significantly abnormal, but any nontender mass especially to the adult is significant enough to warrent further full investigation and follow up, the object of which should be to determine the possibility of malignancy and urgency of treatment. Approach to the diagnosis of the neck mass is so important in that it affects decision regarding further evaluation would lead to the determination of the most efficacious mode of therapy, eventually to the good prognosis. So, it should be emphasized that approach to the diagnosis of neck mass should be planned, systematic and thorough, this begins with the taking careful history following performance of complete examination of the head and neck especially to the nasopharynx, tongue base, pyriform sinus, palatine tonsil and larynx. Then a number of laboratory and radiologic studies are available, following triple endoscopy under general anesthesia and blind biopsy if needed. The most important rule to keep is that any biopsy procedures should be delayed to the last modality of effort to the diagnosis and if it should be done, under the plan of radical neck dissection.

Background and Objectives : The complex physiologic structure of the larynx can vibrate in three or more different ways that yield acuostically and perceptually distinct vocal quality. The purpose of this study is to examine the normal range of voice parameters in Multi-Channel Phonatory Function Analyzer and investigate the difference of voice parameters according to the phonatory patterns. Materials and Methods : Forty normal adult speakers (20 men and 20 women) with age ranging from third to forth decades pronounce low, comfortable, and high tone /a/ ; comfortable tone /${\ae}$/, /i/, /o/, and /u/ : fry, falsetto. Voice was analyzed by Newly developed multi-channel phonatory function analyzer. Results : The normal range of voice parameters in this system was similar to the existing data. Fry shows high jitter and falsetto low SQ. Fry and falsetto show low OQ in men but no difference in women. Jitter, OQ and SQ were different between men and women in modal register, whereas there was no gender difference in fry and falsetto. In frequency magnitude spectrum and EGG, modal register, fry and falsetto have distinguishing pattern. Conclusions : Modal register, fry and falsetto are distinguishable in voice parameters and show different vibratory patterns.

The experience with treatment of acquired subglottic stenosis in 20 adults is reviewed. Nine of the 20 patients (45%) had opeated by other institues before treatment. Causes of the disease were 10(50%) of blunt neck trauama and 10(50%) of prolonged intubation. The most common associated airway diseases were nine patients (45%) of bilateral vocal cord fixations. Twelve patients (60%) underwent anterior cartilage grafts, five patients (25%) had anterior and posterior cartilage grafts and three patients (15%) had end to end anastomosis according to the severity of cricoid deformities and mucosal defects. Associated procedures were 9 patients (45%) of arytenoidectomy. Thirteen of 20 patients (65%) have been decannulated. Fe-male group was significantly higher decannulation rate than male group (p=0.0074). Decannulation rates were decreased from anterior cartilage graft group to anterior and posterior cartilage grafts group and to end to end anastomosis group (p= 0.00247), this finding suggested the patients with severe cricoid deformitiy were higher likely hood of failure because we selected the method used in this study according to the severity of cricoid deformities and mucosal defects. Our results support the more aggressive treatment is indicated for subglottic stenosis in adults.

Background and Objective : Laryngeal Papillomatosis (LP) is the most common benign neoplasm of the larynx, but it tend to recur and it makes eradicating difficult. Meticulous $CO_2$ laser excision has been the most effective treatment to date. This article analyzes the clinical feature and therapeutic results of 42 LP patients who were undergone $CO_2$ laser excision. Methods : Forty two patients with recurrent LP were treated with $CO_2$ laser. And their medical records were reviewed retrospectively. Demographics, chief complaints at onset, initial distribution of papillomas, number of operations performed on each patient, and current results were evaluated. Results : Male in their twenties and forties are dominant in number in patient number. Most common site was anterior one thirds (69%) of glottis area (86%). LP recurred in 17 cases (40%), and in 4 cases, the lesion extended over the original margin. Patients were undergone surgery $1.62{\pm}0.87$ times, $2.53{\pm}0.72$ in recurred cases. Mean relapsing time was 6 momths (from 1momth to 8years). Ant. laryngeal web occurred in 2 cases (4.8%) and 1 case was combined with squamous cell carcinoma. Conclusion : Meticulously performed $CO_2$ laser excision can achieve significant voice and airway improvement and clinical cures. The $CO_2$ laser through microdirect laryngoscopy allows more precise and bloodless removal of papillomas.

Background: Cancer is a major health problem at global level. It is increasingly registered in Iraq and Basrah but the epidemiological situation, though becoming better documented, is still questionable regarding the adequacy of data. Objective: The study aimed to measure the incidence of cancer in Basrah. Materials and Methods: The results presented in this paper are part of a large household survey carried out in Basrah governorate-southern Iraq over a 12 month period (January to December 2013). It involved a detailed interview with adult respondents from each and every household enrolled in the study during a three-year recall period about the incidence of cancer. A total of 6,999 households were covered yielding 40,684 persons. Results: The total number of new cancer cases reported over the three- year recall period (2010-2012) was 112. The average annual incidence rate of all cancers was 91.8 per 100,000 population with a higher rate for females (109.7) compared to males (74.3) The overall age standardized rate was 150.7 per 100,000. The highest incidence rate was recorded for the Southern part of the governorate (Abul-Khasib and Fao ) at 138.8 per 100,000 and the lowest was for East of Basrah (Shatt-Arab District) at 78.0 per 100,000. With respect to cancer types, the main cancers were those of breast, lung, larynx-pharynx, leukaemia, colon-rectum and urinary bladder. These six cancers accounted for 51.5% of all reported cases. Other important cancers were those of brain, bones, pancreas and liver, accounting for a further 17.9%. Conclusions: The pattern of cancer in Basrah is generally similar to the pattern at the national level in terms of age, sex and topography but the incidence rate according to the present household survey is higher than any previously reported figures. Household surveys for cancer seem feasible albeit difficult and costly.
