Diabetes Insipidus after Endoscopic Endonasal Pituitary Macroadenoma Resection: Correlation of Patient and Surgery-Related Risk Factors.

Purpose This article aims to identify patient- and surgery-related factors that could predict the development of postoperative central diabetes insipidus (DI). Methods This is a retrospective case-control study conducted at a single-institution tertiary referral center. Patients undergoing endoscopic endonasal skull base surgery for pituitary adenoma between November 2018 and April 2023 were recruited. The main outcome measures collected include age, gender, comorbidities, tumor type, postoperative DI, intraoperative and postoperative cerebrospinal fluid (CSF) leak, flow of CSF leak, number of layers required for repair, the use of nasal packing, and hospital length of stay. Results A total of 20 patients developed DI postoperatively. Patients' demographic and comorbidity profile did not correlate with DI development. The encounter of an intraoperative CSF leak was correlated with postop DI (chi-square (1) = 18.35, p < 0.001) with a relative risk (RR) of 2.7 (confidence interval [CI] = 1.37-5.28). The use of nasal packs was also correlated with postop DI (chi-square (1) = 10.17, p = 0.001) with a RR of 1.8 (CI = 1.15-2.87). Defects requiring a two or more layers for reconstruction also correlated with postop DI compared to single layer repairs (chi-square (1) = 12.15, p < 0.001) irrelevant of the materials used. Development of DI postop correlated with an increased hospital length of stay ( t (64) = -3.35, p = 0.001). Conclusion The physician should be careful when evaluating patients with pituitary adenomas in the postoperative period, particularly those with intraoperative CSF leak, nasal packing, and those who underwent multilayer reconstruction of the surgical defect.

The use of different intranasal splints Doyle splints versus Reuter bivalve splints versus no splints in primary septal surgeries: A randomised clinical trial looking at morbidity.

OBJECTIVE: The objective of this study is to compare the morbidity of different types of intranasal splints (Doyle splints and Reuter bivalve splints) with no intranasal splints in primary septal surgeries and concomitant submucosal reduction of the inferior turbinate. DESIGN: Randomised clinical trial SETTING: Single-Center trial at a tertiary care facility PARTICIPANTS: In this randomised clinical trial, 123 consecutive patients underwent primary septoplasty with bilateral submucosal reduction of the inferior turbinate, with no other concurrent procedure. Patients were randomised into three groups: Doyle splints, Reuter bivalve splints and patients with no splints placed. MAIN OUTCOME MEASURES: Following surgery, the patients were seen at three consecutive visits. During each visit, the Visual Analogue Scale score for headache, nasal obstruction, overall pain and bleeding and an endoscopic score for secretions, oedema and synechiae was filled. RESULTS: Patients were randomised into three groups, 42 received Doyle splints, 41 Reuter bivalve splints and 40 had no splints inserted. When comparing the three groups, the first two post-op visits were scheduled significantly earlier in patients with splints (p < .05). The scores from both groups with splints were statistically higher for headache, nasal obstruction and pain, for the first visit only (p < .05). There was no statistical difference between groups when looking at each subset of the endoscopic score, at each visit (p > .05). CONCLUSION: Increased post-operative pain, headaches and nasal obstruction scores were encountered in patients who had splints after surgery. However, endoscopic scores were statistically similar across the three groups with no difference in post-operative endoscopic scores at each visit. and no difference was seen in symptom scores and endoscopic scores between patients with different splints.

Tips and Tricks to Safely Perform an Endoscopic Endonasal Trans-Sphenoidal Pituitary Surgery: A Surgeon's Checklist.

The authors aimed to develop an extensive preoperative checklist of CT scan findings during endoscopic access to the ventral skull base and implement it in clinical practice. A comprehensive literature review was conducted to identify the radiological landmarks crucial to endoscopic skull base surgery. Four electronic databases were searched: PubMed, MEDLINE, EMBASE, and Google Scholar using search terms/keywords such as "radiological landmarks," "endoscopic skull base surgery," "CT scan," "pituitary surgery," "anatomical variations," "internal carotid," "optic nerve," "sphenoid sinus," "pneumatization," "dehiscence," and "protrusion". Inclusion criteria were limited to original articles and systematic reviews published in English, between the years 2000 and 2021, which pertained to the radiological landmarks to be identified during endoscopic skull base surgery. Full-text articles were retrieved and collated into a narrative review focused on a 12-item checklist the authors agreed upon. The mnemonic "O ROAD TO SELLA" was used to represent the checklist and include the following landmarks: Sphenoid Ostium, Sphenoid Rostrum, Onodi cells, Anatomic variations of the sphenoid sinus, Distance between the carotids, Tumor characteristics, Optic nerve dehiscence/protrusion, Septation/insertion of the sphenoid sinus, Entrance to the sellar floor, Lateral recess of the sphenoid sinus, cLinoid process pneumatization, and internal carotid Artery dehiscence/protrusion. The checklist is designed to be used by attending physicians, fellows, and residents and the authors intend to implement it into electronic medical records at the institution's medical center to monitor the outcomes of EEPS after implementation.

Hyaluronic Acid in Rhinology: Its Uses, Advantages and Drawbacks-A Review.

Hyaluronic acid has been increasingly involved in recent research due to its many chemical and physical properties. This is a review of the literature for studies involving the use of hyaluronic acid in rhinology. Hyaluronic acid washes and irrigation have been increasingly used in chronic sinusitis medical therapy and post-operatively with mixed results. It has also been shown to play a role in the treatment of nasal polyposis, allergic rhinitis, acute rhinosinusitis and empty nose syndrome. Its effect on biofilm in many disease entities has also been studied. HA is being recently used as ancillary treatment for several rhinologic conditions such as post-operative endoscopy care and chronic sinonasal infections. The properties of HA have intrigued researchers over the past years particularly in biofilm management, healing and inflammation.

A Venous Malformation of the Inferior Turbinate: A Case Report with Review of the Literature.

Arteriovenous Malformations of the head and neck are rare vascular anomalies that can be aggressive and lethal. It is crucial to have a high clinical suspicion to avoid the consequent mortality and morbidity that may result from bleeding. We present the case of a rare inferior turbinate venous malformation in a 17 year old female that presented with epistaxis and was treated with surgery. Treatment varies and depends on the stage; however complete resection should be the goal to prevent recurrence. The endoscopic endonasal approach is minimally invasive, safe and effective in selected patients.

Standard Endoscopic Approaches in Frontal Sinus Surgery: Technical Pearls and Approach Selection.

The mainstay of frontal sinus surgery for chronic rhinosinusitis is to achieve and maintain an adequate frontal outflow tract. Using a stepwise approach and identifying critical endoscopic anatomic landmarks, to minimize complications and obtain long-term good endoscopic surgical results, should achieve this. The goal is to relieve the patient's symptoms, restore functional mucociliary flow, achieve a wide frontal sinus ostium and prevent long-term scarring and stenosis. Meticulous dissection and appropriate use of instrumentation and techniques aids in preventing unnecessary damage to normal mucosa while achieving one's goal of an adequate surgical ostium.

Solitary hydatid cyst of the thigh: a challenging diagnosis.

A 53-year-old woman presented with an enlarging mass in the medial aspect of her right thigh. Magnetic resonance imaging suggested an intramuscular hydatid cyst. The cyst was surgically excised. Although muscular hydatidinosis is rare, its resemblance to soft tissue tumors warrants careful diagnosis since any invasive diagnostic measures may lead to fatal complications.
