Development and testing for an operative competency assessment tool for nasal septoplasty surgery.

Background Assessing surgical competency in otolaryngology is challenging, and residency programs are now responsible for ensuring the surgical competency of their graduates. Therefore, more objective assessment tools are being incorporated into the evaluation process. Objective structured assessment of technical skills (OSATSs) tools have been developed for multiple otolaryngology procedures. These include tonsillectomy, endoscopic sinus surgery, thyroidectomy, mastoidectomy, direct laryngoscopy, and rigid bronchoscopy. The purpose of this study was to develop and test a new assessment tool for septoplasty surgery and ensuring its feasibility, reliability, and construct validity. This study was designed develop an test a valid, reliable, and feasible evaluation tool designed to measure the development of trainees’ surgical skills in the operating room for septoplasty surgery. Methods A new OSATSs-based instrument form for septoplasty was developed. During the study period of 2 years, 21 otolaryngology–head and neck surgery residents (ranging from postgraduate year 2 to 5) were evaluated intraoperatively by on faculty member obtaining al of 175 evaluations. Surgical performance was rated using a seven-item task-specific checklist (TSC) and a global rating scale (GRS). The TSC assessed specific septoplasty technical skills, and the GRS assessed the overall surgical performance. Results Our tool showed construct validity for both components of the assessment instrument, with increasing mean scores with advancing clinical levels. Cronbachs α, a measure of internal consistency, was 0.911 for TSC and 0.898 for GRS. Strong correlation between the TSC and GRS was established (r = 0.955; p < 0.01). Conclusion This study proved our educational tool to be a valid, reliable, and feasible method for assessing competency in septoplasty surgery. It can be integrated into surgical training programs to facilitate direct formative feedback. Assessing trainees’ learning curves enables insight into their progression, ensuring their appropriate development.

Variations of lamina papyracea position from the endoscopic view:a retrospective computed tomography analysis

Accidental injury of lamina papyracea (LP) remains one of the most common complications reported in endoscopic sinus surgery (ESS) even in most recent studies. The purpose of this study was to categorize the LP position radiologically and from an endoscopic perspective.

Desmoid tumor (fibromatosis) of the head and neck

Desmoid tumors (fibromatosis) are rare benign tumors, they arise from musculoaponeurotic structures throughout the body. They are locally infiltrative, resulting in a high rate of local recurrence following surgical resection. Due to the rarity of these tumors in the head and neck region, we report a case of a patient with a desmoid tumor in the upper neck that was diagnosed and treated in our institution, to increase the awareness of the Otolaryngology-Head and Neck surgeons, and report available treatment options of this condition.

Acute rhinosinusitis during Hajj season 2014: Prevalence of bacterial infection and patterns of antimicrobial susceptibility

BACKGROUND The presence of large number of pilgrims during Hajj in Makkah region increases the risk of respiratory diseases. In this study, we aimed to assess the bacteriology of acute rhinosinusitis (ARS) during Hajj season and to demonstrate the antimicrobial susceptibility patterns that should guide the clinicians towards more appropriate antibiotic use. METHODS Patients with ARS presenting during Hajj season of 2014 were prospectively enrolled. According to EPOS2012 criteria. Sampling of sinus secretions was performed from the middle meatus adjacent to the maxillary sinus ostium via endoscopic guidance. Over all, the study has covered all ENT, emergency and outpatient departments in Hajj. RESULTS Two hundred and twenty six patients with ARS were enrolled in the study. Pathogenic bacteria were identified in 93 (41.2%) patients. Of the 93 patients with bacterial ARS, Staphylococcus aureus was isolated in 46 (49.5%) patients, out of which 13 (28.3%) were methicillin-resistant Staphylococcus aureus (MRSA).The second most common group of bacterial isolates was Enterobacteriaceae such as Escherichia coli, and various Klebsiella species. Antibiotic sensitivity showed that methicillin-sensitive Staphylococcus aureus (MSSA) was also sensitive to cephalosporins, quinolones and clindamycin, while exhibiting relatively less sensitivity rates to amoxicillin-clavulinic acid and macrolides. CONCLUSION Our study demonstrates the importance of assessing the bacteriology of ARS to help implement guidelines for proper treatment and prevention protocols during Hajj season.

Percutaneous ultrasound-guided alcohol ablation of solitary parathyroid adenoma in a patient with primary hyperparathyroidism.

Parathyroidectomy is considered the definitive cure for primary hyperparathyroidism due to a single parathyroid adenoma, which represents the most common cause of chronic hypercalcemia. However, in few cases, surgery may be technically difficult or risky. We report the use of percutaneous ultrasound-guided alcohol ablation of a parathyroid adenoma as an alternative to surgery in an 88-year-old male patient with significant medical comorbidities.

Retromaxillary Pneumatization of Posterior Ethmoid Air Cells Novel Description and Surgical Implications

Objective Retromaxillary pneumatization of posterior ethmoid (PE) air cells is an area that is yet to have appropriate description in rhinologic literature. Study Design Case series with chart review. Setting Tertiary care hospital. Subjects and Methods First, 524 sides in 262 paranasal sinus computed tomography scans were analyzed: 350 normal sides were examined for PE pneumatization lateral to the sagittal plane of the medial wall of maxillary sinus posteriorly, and 174 diseased sides were similarly reviewed to check how pathology may affect identification and measurements. Following that, 153 operated sides in 84 cases prepared for revision endoscopic sinus surgery (ESS) were studied for residual diseased cells at different anatomic locations. Results Overall, retromaxillary PE pneumatization was identifiable in 416 of the 524 sides (79.4%). Lateral retromaxillary extension varied from 0.5 to 12.3 mm (mean ± SD, 4.8 ± 2.3 mm). This area of pneumatization is bounded anteroinferiorly by the junction between the posterior and superior walls of the maxillary sinus. Three cell types were described depending on the degree of lateral extension (type I, <3 mm; type II, 3-6 mm; type III, >6 mm). This cell, which we refer to as the Herzallah cell, was distinguishable from the anterior ethmoid Haller cell and was found to have residual disease in 50.3% of cases prepared for revision ESS. Conclusion Retromaxillary extension of PE air cells varies considerably and requires attention during ESS. Residual undissected retromaxillary cell is a common finding in revision ESS and can contribute to inadequate disease clearance.

Avastin and diode laser: A combined modality in managing epistaxis in hereditary hemorrhagic telangiectasia

A patient with hereditary hemorrhagic telangiectasia is a rare presentation to the otolaryngologist in clinical practice. They almost present with epistaxis, which is recurrent, spontaneous and can be functionally and socially debilitating for the patient. Diode laser cauterization and Avastin intranasal injection showed significant improvement in epistaxis severity score. We report a case of hereditary hemorrhagic telangiectasia with chronic epistaxis (hemoglobin 3.4 mg/dl) managed with Diode laser and intranasal Avastin injection with great improvement in life quality and decrease in epistaxis attacks. Despite all treatment options absolute eradication of epistaxis attacks is difficult to obtain in these cases.

Endoscopic anatomy of the lacrimal sac for dacryocystorhinostomy. A cadaveric study

Objectives: To assist the endoscopic localization of the lacrimal sac (LS) relative to nearby landmarks. Methods: This is a descriptive prospective anatomical study. Sixteen lateral nasal walls were dissected endoscopically to identify and localize the LS between October and November 2015. Multiple measurements were obtained from the NS to the anterior and posterior walls of the LS, as well as to the middle turbinate axilla (MTA) and from the MTA to the LS borders. Results: The average distance from the NS to the anterior border of the LS was 42.0 mm and the posterior border was 48.5 mm. The average widths of the LS were 7.55 mm superiorly, and 6.6 mm inferiorly representing a mathematical proof that the LS is a trapezoid shape. The mean distance from the NS to the MTA was 47.3 mm. Nine of the 16 lacrimal sacs (56.3%) were found to be partially overlapped by the MTA. The LS was only totally overlapped and lying posterior to the MTA in one side (6.3%), while in 6 sides (37.5%) the LS lay anterior to the MTA. Conclusion: Endoscopic surgeons should be aware of the location of the LS relative to nearby landmarks, particularly the MTA. Representing a mathematical proof that the LS is wider at it upper part than lower part best presented as a trapezoid shape. We have provided additional measurements that may prove useful in cases of difficult exposure.

Foreign body mimicking malignancy in acquired dacryocystocele

A featured malignant‐like granulation tissue can be the only preoperative clinical clue of a concealed foreign body in the nasal cavity. Thus, endoscopic Dacryocystorhinostomy (DCR) should be completed with intraoperative nasal exploration to reveal non‐apparent foreign bodies that might be the underlying etiology of chronic dacryocystocele.

Comparison of two approaches to lateral nasal osteotomy in Saudi patients

BACKGROUND Nasal deformity is an abnormality in the appearance of the nose due to either congenital defect or trauma. In traumatic cases, patients often present with combined functional and cosmetic complaints. Therefore, otolaryngologists take into account both breathing and aesthetic nasal issues. OBJECTIVES To evaluate the changes in the nasal dorsum and base; compare breathing and aesthetic satisfaction scores between two approaches to lateral nasal osteotomy: low-to-low and low-to-high. DESIGN Comparative observational; data gathered retrospectively and prospectively. SETTING Head and Neck and Skull Base Center, King Abdullah Medical City, Makkah, Saudi Arabia. PATIENTS AND METHODS Patients who received hump reduction rhinoplasty from 2013 to 2016 met the inclusion criteria. MAIN OUTCOME MEASURE(S) The differences in dorsal (DW) and ventral (VW) widths with a fixed interpupillary distance (IPD). Satisfaction scores for both cosmetic perspective and breathing functionality. RESULTS We included 46 patients; 28 patients underwent low-to-low osteotomy and 18 patients underwent low-to-high osteotomy. With both approaches, there were statistically decreases from preoperative to postoperative ratios of VW/IPD and DW/IPD. However, differences in DW/IPD ratio and VW/IPD ratio (pre- versus post-op) were significantly higher in the low-to-low group (P<.0001). All showed breathing satisfaction postoperatively regardless of the operative approach. Only patients who underwent the low-to-high osteotomy were neutral or dissatisfied with aesthetic sensibility. CONCLUSION Both types of osteotomy showed a satisfactory outcome in both objective and subjective measures. However, low-to-low osteotomy was superior in pre- to post-operative differences in DW/IPD and VW/IPD ratios. LIMITATIONS Sampling was by convenience. The study was conducted in a single tertiary center and was a small sample.
