Objective to determine the anterior ethmoidal artery (AEA) anatomy and variations by computed tomography (CT) in adult and their relations to and presents new AEA classifications. Methods One hundred and fifty paranasal CT scans (300 sides) were included. Axial images were acquired with multiplanar reformates to obtain delicate details in coronal and sagittal planes. Results One hundred and forty-four AEAs canal (48%), 293 AEAs foramen (97.7%), and 229 AEAs sulcus could be detected (76.3%). The mean AEA intranasal length was 6.7 ± 1.27 mm (range: 4.24–10.6 mm). The mean angle between AEA and lamina papyracea was 105.49 ± 9.28 degrees (range: 76.41–129.76 degrees). Of them, 95.8% AEAs had an angle with lamina >90 degrees, while 4.2% had angle <90 degrees. The mean angle between AEA and lateral lamella of cribriform plate was 103.95 ± 13.08 degrees (range: 65.57–141.36 degrees). Of them, 87.5% AEAs had an angle >90 degrees and 12.5% had an angle <90 degrees. The mean distance between AEA and skull base was 1.37 ± 1.98 mm (range: 0–8.35 mm). The AEA types in relation to skull base was type 1 (0–2 mm from skull base; 64.6%), type 2 (2–4 mm; 22.2%), type 3 (4–6 mm; 11.1%), and type 4 (>6 mm; 2.1%). The mean distance between the AEA and frontal sinus ostium was 9.17 ± 4.72 mm (range: 0–25.36 mm). AEA classification according to distance from AEA to frontal sinus ostium was 17.4% type 1 (<5 mm), 41.7% type 2 (5–10 mm), 31.9% type 3 (10–15 mm), and 9% type 4 (>15 mm). Conclusion Provided AEA details improve surgeons' awareness of AEA variations in the endoscopic field and can help residents in training.

Introduction Tracheostomy is the commonest surgical procedure in intensive care units (ICUs). It not only provides stable airway and facilitates pulmonary toilet and ventilator weaning, but also decreases the direct laryngeal injury of endotracheal intubation, and improves patient comfort and daily living activity. Objective The objective of this study is to assess the incidence, indications, timing, complications (early and late), and the outcome of tracheostomy on patients in the intensive care units (ICU) at a university hospital in a developing country. Methods This study is an observational prospective study. It was performed at the otolaryngology department and ICU new surgery hospital on 124 ICU admitted patients. We collected patients' demographic records, cause of admission, indications of tracheostomy, mechanical ventilation, and duration of ICU stay. We also gathered patientś tracheostomy records including the incidence, timing, technique, type, early and late complications, and outcome. All tracheostomized patients received follow-up for 12 months. Results The indication for tracheostomy in ICU patients was mostly prolonged intubation (80.5%), followed by diaphragmatic paralysis (19.5%). All tracheostomies were done by the open approach technique. Tracheostomy for prolonged intubation was done within 17 to 26 days after intubation with a mean of 19.4 ± 2.07 days. Complications after tracheostomy were 13.9% tracheal stenosis and 25% subglottic stenosis. Conclusion Prolonged endotracheal intubation is the man indication of tracheostomy, performed after two weeks of intubation. Although there were no major early complications, laryngotracheal stenosis is still a challenging sequel for tracheostomy that needs to be investigated to be prevented.

OBJECTIVE:To determine if the wet ear at time of surgery adversely affects the success rate of myringoplasty operations. MATERIALS and METHODS:A total of 46 wet ears (with mucoid discharge) and 52 dry ears (at least 1 month before surgery) with mucosal chronic suppurative otitis media were operated on by myringoplasty. Graft take and hearing gain rates 6 months after surgery were calculated for both groups and compared. RESULTS:The graft take rate was 87% for the wet ear group and 90.4% for the dry ear group. The hearing gain rate was 91.3% for the wet ear group and 92.3% for the dry ear group. Differences were found to be statistically nonsignificant for both graft intake (p=0.665) and hearing gain (p=1.00). CONCLUSION:The success of myringoplasty is not adversely affected by the presence of mucoid ear discharge at time of surgery, and outcomes are comparable to those of the operation done for dry ear.

This study aimed to evaluate the operative outcomes of using gastric pull-up (GPU), pectoralis major myocutaneous flap (PMMF), and jejunal free flap (JFF) to reconstruct the hypopharynx after resection of hypopharyngeal and cervical esophageal carcinoma. Retrospective clinical study. Otolaryngology Department, Zagazig University Hospital, Egypt and Surgical Department, National Cancer Institute, Cairo, Egypt. Records of 104 patients who underwent resection of carcinoma of the hypopharynx and cervical esophagus were reviewed to determine the indications for radical resection, location, and stage of the primary tumor, gross and pathological surgical resection margins, operative complications, morbidity, and mortality. Reconstruction was performed using the GPU for group (1) (n = 33), PMMF for group (2) (n = 34), and JFF for group (3) (n = 37). The hypopharynx was the most common primary tumor site for group (2) and group (3) whereas group (1) had lesions more frequently in the cervical esophagus. The overall postoperative morbidity rate was 20.2% with a perioperative mortality rate of 6.7% and there was no significant difference between the three groups. There was no graft necrosis in group (1) compared to 5.9% in group (2) and 5.4% in group (3). Pulmonary complications occurred commonly (30.3%) in group (1) compared to 11.8% in group (2) and 10.8% in group (3) The overall 3 years survival rate was 67.3% and there was no significant difference between the three groups. The outcomes of the three techniques are equally successful when used appropriately. The nature of the defect indicates the method of reconstruction. For short reconstruction above the thoracic inlet, PMMF or JFF are equally effective and in tumors requiring total esophagectomy, GPA is indicated.
