“…Mean age in posttraumatic head and neck defects was 26.42 years. This is in accordance with results observed by Patrick Cole et al, (4) Murray dJ et al (5) and Turvey TA. (6) This age group is more exposed to risks like accidents while driving, working outdoor, drinking brawls, tobacco, gutka etc.…”

BACKGROUND: Local and locoregional flaps are very useful in reconstruction of head and neck defects. Each case should be judged on its merits and selection of flap (local or locoregional) should be done by considering various factors. AIM: To study the etiological factors, type, distribution, management of head and neck defects (post traumatic, post malignancy & congenital) by using local and locoregional flaps and the overall cosmetic effect and function of both donor as well as recipient sites. MATERIAL AND METHODS: 40 patients were studied in a multispecialty hospital admitted in the trauma unit or as OPD patients. After stabilization, especially in trauma patients, patients were fully investigated and treatment protocol was made and reconstruction was done as per protocol. RESULTS: In this study, the mean age of patients was 29.8 years. The main cause of head and neck defects was post traumatic (58%) followed by malignancy (23%), infections (10%) and others (9 %). The mean age for post traumatic defects was 26.42 years. In post malignant defects, Basal cell carcinoma was the major cause of defect (50%) followed by oral malignancy (54%). All the patients with oral carcinoma were tobacco chewers and 50 % were alcoholic. Middle third of face (67%) was most common site for defect followed by scalp (14%), upper third (7%) and lower third face (6%). In the middle third of face, nose (38%) was commonest site of defects followed by cheek (34%) and ears (28%). Local flaps were used in 38% of defects as compared to locoregional flaps (62%). Advancement flaps were mainly done for cheek defects (70%). Rotation and transposition flaps were done mainly for scalp defects. Most common locoregional flap done was median forehead flap (27%) followed by deltopectoral flap. CONCLUSION: Local and locoregional flaps are still very useful in reconstruction of head and neck defects. This is in accordance with Gille's rules of reconstruction i.e." like replaces like". Treatment of the head and neck defects should be individualized. Each case should be judged on its merits and selection of flaps (local or locoregional) should be done by considering various factors like type of defect, site of defect, amount of associated injuries, and the condition of adjacent skin.

Purpose To study effects of zygomatico maxillary fractures and fracture reduction on intra ocular pressure (IOP). Materials and methods IOPs of 20 patients with unilateral zygomatico-maxillary complex (ZMC) fractures (divided into 2 groups of 10 undisplaced, 10 displaced) were measured at various time intervals. The relationship between IOPs between the two groups at various time intervals was recorded and evaluated using independent T-tests. Results 20 subjects were divided into two equal groups (10 each of displaced and undisplaced fractures). Mean age of patients was 33.8 years with 90 % males and 10 % females. The change in IOP at the time of reporting, after 24 h and 7 days for patients with undisplaced ZMC fractures (Group I) was recorded and was found to be significant. The change in IOP at the time of reporting, before and after surgery, after 24 h and 7 days for patients with displaced ZMC fractures (Group II) was recorded and was also found to be significant. The IOPs of the two groups was compared at various time intervals and was found to be significant. Also, a significant increase in IOP was noted just after fracture reduction, which could be attributed to oculocardiac reflex, which has been proven to cause bradycardia, and in some cases, even death. Conclusion A cautious eye needs to be kept over IOP while reducing ZMC fractures at regular intervals and the anaesthetist has to be informed to look for any bradycardia that can occur. Tonometers should be a part of standard armamentarium while reducing and fixing ZMC fractures.

Background: Zygomatic fracture is one of the most prevalent one among facial fractures caused by vehicle accident, motorcycle accident, fighting, fall and sport injuries. Materials & Methods: This study was a retrospective study of our patients during past 6 years. Results: We had 1277 facial fractures, of whom 9 patients had blindness. We had 193 patients with Zygomatic fracture. 98 patients had pure zygomatic fracture and other had complicated fractures. Frequency of blindness due to zygomatic fracture in a period of six years was 4.7% in all and in pure zygomatic fractures was 2.04%. Blindness was most prevalent in age group 20 -29 years old (55.6%). The most prevalent cause of zygomatic fracture which causes blindness, was motor vehicle accident (77.8%). Blindness was more common in males (77.8%) than females (22.2%). Discussion and Conclusions: One of the most disastrous complication of zygomatic fracture is transection of optic nerve. Very careful examination of fractured bones careful examination of optic nerve and visual acuity and urgent operation and decompression of optic nerve must be performed. About 4% -5% will have blindness purely due to fracture.

Intraocular Pressure Variations during Zygomatic Fracture Reduction and Fixation: A Clinical Study

Abstract: The surgical reduction of uncomplicated zygomatic fractures has no adverse effect on the intraocular pressure. It is the authors' opinion that adjunctive measures to reduce the pressures are unnecessary.
