<p class="abstract"><strong>Background:</strong> Deviation of normal pulmonary functions leads to dysfunction of the respiratory system and this affects the functions and vitality of other related systems. Pulmonary function tests give valuable information on the state of airways, lung volumes and lung function. Hence, the present study aimed to evaluate the effectiveness of septoplasty on pulmonary function tests in symptomatic deviated nasal septum cases.</p><p class="abstract"><strong>Methods:</strong> A total of 35 patients (septoplasty: 31; septorhinoplasty: 4) with deviated nasal septum were involved in the study. Demographic data, clinical and physical examination including anterior and posterior rhinoscopy was performed. RMS Helios 702 spirometer was used to perform pre- and postoperative pulmonary function tests. Forced vital capacity (FVC), forced expiratory volume (FEV1) in 1 second, peak expiratory flow rate, and the ratio of FEV1 to FVC were the parameters measured. SPSSV. 17 was used to analyse the data.  </p><p class="abstract"><strong>Results:</strong> The deviation was most commonly seen on the left side (54%), affecting mostly the cartilaginous septum (54%). Among patients with septoplasty, the postoperative values of FVC (p&lt;0.05), FEV1 (p&lt;0.05), and peak expiratory flow (p&lt;0.05) were higher than the preoperative values and the results were statistically significant. Age, gender, laterality and duration of deviation, headache and inferior turbinate hypertrophy did not play a significant role in the enhancement of pulmonary functions after septoplasty.</p><p class="abstract"><strong>Conclusions:</strong> A favorable outcome in pulmonary function was observed in patients with deviated nasal septum after septoplasty. However, due to limited sample size, it is advisable to conduct the study in a larger sample to validate these results.</p>

Observing the origin, varied branching configurations of superior thyroid artery (STA) and evaluating morphometric details with its surrounding relations was aimed at in this cadaveric neck dissection study to avoid surgical mishaps and its repercussions. This observational study was conducted on 40 fresh frozen embalmed and colored latex infused cadavers in the Department of Otorhinolaryngology and Head and Neck Surgery in collaboration with Department of Anatomy of our institute, which involved systematic evaluative dissection of both sides of neck especially focusing on superior thyroid artery, its branching variations and morphometric details with its surrounding relations. Details were measured using digital caliper. The collected data was statistically analyzed by applying chi-square test and significance was set at 5% level (p \ 0.05). The analysis revealed the location of the origin of the superior thyroid artery of cadavers from carotid bifurcation and above it in 40% and from above the level of superior border of thyroid cartilage in 40% of cases. The distribution patterns of the superior thyroid artery were classified into three types depending on the branching pattern typical and variant glandular branching patterns were observed in 85% and 15% of the specimens respectively. A sound knowledge of the regional anatomy and its possible variations helps the surgeon in isolating and preserving the vital structures and avoid iatrogenic complications.
