RESUMO
The role of Drug-induced sleep endoscopy as a selection tool for surgical management of obstructive sleep apnoea syndrome. SOURCE OF DATA: Polysomnography proved OSA patients, who are planned for surgery in dept. of ENT AND HEAD& NECK, JSS Hospital, Mysore. STUDY DESIGN: A prospective clinical study. METHOD: 30 Polysomnography proved OSA patients, age between 20 and 60 years have been selected for Drug Induced Sleep Endoscopy (DISE) after taking informed consent for proposed surgery. Inj propofol infusion given throughout the DISE procedure and upper airway nasal endoscopy performed for assessment of site of collapse (Retropalatal, Retrolingual, Hypopharyngral), type of collapse (circumferential, lateral) and severity of obstruction, Lowest SpO2, apnoeic episodes and DISE findings were recorded. Out of these thirty patients 90% were male and 10% were female, observed that 66.7% of males and 40.7% of females belonged to 31-40 age group, and BMI of 63.3% of patient population were overweight, 20% were obese and 5% were normal. Mean fall in SpO2 was 90.20 ± 2.77 in normal subjects, 83.05 ± 5.14 in overweight subjects and 68.83 ± 9.11 in obese subjects. Normal subjects had 0.4 ± 0.9 apnoeic episodes, overweight subjects had 0.9 ± 1.6 episodes and obese subjects had 4.0 ± 2 apnoeic episodes. We observed that 40% had retropalatal airway collapse, 23.3% had airway obstruction at the base of the tongue, 20% had airway obstruction with floppy epiglottis, 12% multiple level collapse, 6.7% of patient population had grade 4 enlarged tonsils, 3.3% had lateral pharyngeal wall collapse, and 0% hypopharyngeal collapse. Out of 30, 29 Patients underwent surgery (Expansion sphincter pharyngo plasty-14, Hyoid advancement-4, Uuvulopalatoplasty-10, Epiglottic surgery-6, Zeta pharyngoplasty-2, midline glossectomy-3, Endoscopic septoplasty-5, Inferio turbinoplasty-2, LASSER Assisted lingual tonsillectomy-1), All these 29 patient were followed for 3 months, at the end of 3rd month again Each subject was evaluated with a baseline Epworth Sleepiness Scale and LEVEL-3 PSG, the results were impressive with statistically significant. DISE is a dynamic, safe, and easy-to-perform technique that visualizes, the anatomical sites of snoring or apneas for assessment site of collapse (Retropalatal, Retrolingual, Hypopharyngral), type of collapse (Circumferential, Lateral) and severity of obstruction and guides the design of a tailor-made treatment plan for a OSA SURGEON in individual cases, which will improves perioperative outcome.
RESUMO
Satisfactory reconstruction of complex maxillo-mandibular defect in a single stage has been a surgical challenge. This is particularly because it necessitates a flap which will reconstruct both the maxilla and mandible along with any associated soft tissue defect, mucosa or skin without adding to functional and cosmetic problems for patient and technical problems for the surgeon. Here we describe an innovative design for simultaneous reconstruction of maxilla, mandible, soft tissue and mucosal lining in one stage using a single fibula osteocutaneous flap.

Reconstruction of soft-tissue defects of the lower third of the leg, the heel and the foot remains a challenge. The distally based sural neurocutaneous flap has been used effectively to resurface these defects. However, the paucity of bulk in this flap makes it inadequate for complex post-traumatic or post-ablative soft-tissue reconstruction. We dissected 20 freshly amputated lower limbs after injecting them with a mixture of lead oxide and gelatin. We found muscular branches of the accompanying artery of the sural nerve to the gastrocnemius muscle in all 20 limbs. This led us to conceptualise the distally based venoneuroadipofascial pedicled island sural myofasciocutaneous and muscle flaps. These flaps are useful for the reconstruction of complex soft-tissue defects of the lower third of the leg, the heel and the foot.

Complex soft-tissue defects of the lower third of the leg, the heel and the ankle still present a challenge for the reconstructive surgeon. In addition to skin replacement, many of these defects require muscle bulk, which promotes the healing of open bone fractures, effectively fills osteomyelitic cavities and deep three-dimensional defects, and helps to reconstruct the Achilles tendon. In an anatomical study, we developed a new flap based on the 'neuromuscular concept'. This flap consists of a paddle of gastrocnemius muscle and a skin paddle based distally on the sural venoneuroadipofascial pedicle supplied by the lower peroneal perforators. Three cases are presented to illustrate the versatile use of this flap.
