These grafts in a minority of patients, a study by Toriumi et al revealed that will provide the internal lining and cartilaginous support to patients were willing to accept this in light of the relief in nasal resist contraction and reformation of the cicatricial stenosis. When this corresponds with the nasal ala (uncom- tion, rerotation, and suspension of the nasal tip to correct the mon), it is referred to as an alar batten graft. One way to improve tip pro- the nasal sidewall or intervalve area, the graft is referred to as a jection is to disarticulate the medial crura and resecure them to sidewall batten graft. Conchal cartilage serves as an excellent the caudal border of the septal cartilage, increasing projection. The graft is placed in a soft tissue pocket extending to the bony pyriform aperture. The graft is placed at the epicenter of collapse, at the intervalve area (a, left) or at the external valve (a, right). Conchal cartilage placed at the (b) intervalve area and at the (c) external valve.

Treatment consists of transposition When placed through the open approach, a soft tissue pocket of the malformed lateral crura into a more physiologic position. The graft is secured with a obstruction when reducing tip bulbosity—especially when rapidly absorbing suture placed through the nasal mucosa, pull- dome-binding sutures are placed. The crural strut graft uses cartilage harvested from the septum or pocket is typically placed parallel to the supra-alar crease. The figure demonstrates use of a graft extending to the pyriform aperture, providing additional support. On occasion, face of the middle turbinate is incised using a sickle blade, and this maneuver alone will help straighten the lateral crus.

A Chorioamnionitis B Pelvic girdle pain C Placental abruption D Preterm labour E Pyelonephritis F Red degeneration of fbroid G Torsion of ovarian cyst H Urinary tract infection I Uterine rupture The following clinical scenarios relate to women experiencing pain in pregnancy. There is no vaginal bleeding or history sugges- tive of ruptured membranes and fetal movements are normal. On examina- tion the uterus is irregular, large for dates, and tender over the fundus. F Red degeneration of ﬁbroid The salient feature here is her ethnic origin; fbroids are more common in African women, and the uterus is irregular. You will know from your revision that fbroids can undergo red degeneration in pregnancy even if you’ve never seen a case. Because the pain is continuous it makes the option of preterm labour unlikely even though it is a more common condition. The pain could be due to a concealed abruption but the whole uterus would be tender and abruption usually causes fetal distress. She gives a history of losing ﬂuid per vaginam intermittently over the preceding 3 days. The pain is described as ‘generalised’ rather than intermittent (which might suggest option G – preterm labour). The small for dates uterus would ft with oligohydramnios due to ruptured membranes. On examination her blood pressure is 170/110 mmHg, pulse 100 bpm, and she is apyrexial. On abdominal palpation the uterus is hard and tender and the fetal heart cannot be detected. C Placental abruption The salient features in this case are the severe hypertension and proteinuria sug- gesting pre-eclampsia, the lack of fetal movements, and absent fetal heart suggest- ing an intrauterine death and the hard uterus suggesting the Couvelaire uterus of a large abruption. From your revision you know that abruption is a complication of pre-eclampsia and don’t be distracted by the absence of vaginal bleeding as even large abruptions can be concealed. A Await result of fetal anomaly scan at 20 weeks of gestation B Inform the woman that Down syndrome is confrmed C Inform the woman that Down syndrome is excluded D Inform the woman that the risk for this pregnancy is low E Nuchal translucency scan at 11–13 weeks of gestation F Offer amniocentesis G Offer chorionic villus sampling H Offer Cordocentesis I Serum screening at 15–17 weeks of gestation These clinical scenarios relate to women seeking prenatal testing for Down syn- drome. The quickest result would be obtained by chorionic villus sampling because active placental cells will be dividing quickly enough to obtain a karyotype within 24–48 hours. Cordocentesis is reserved for later in pregnancy to investigate seri- ous and rare conditions like fetal anaemia. She is concerned about the risk of having a baby affected by Down syndrome and wishes to have a diagnostic test with low- est possible risk of miscarriage. F Offer amniocentesis The patient wants a diagnostic test and the one with lowest risk of pregnancy loss is amniocentesis. She has serum screening only done for Down syndrome and the result shows a 1 in 5,000 risk of the pregnancy being affected. D Inform the woman that the risk for this pregnancy is low Screening tests do not exclude Down syndrome but this low risk result is reassuring. A Delivery by caesarean section at 37 weeks of gestation is recommended B Elective caesarean section carries less fetal risks than vaginal birth C Emergency caesarean section in labour is as safe as elective section D Induction of labour is contraindicated E Induction of labour is recommended at 40 weeks of gestation F Pregnancy could continue to await spontaneous labour G The risk of scar rupture/dehiscence in labour is 10 per cent H Vaginal delivery is contraindicated for maternal reasons I Vaginal delivery is only possible if expected fetal weight is <4000 g Each of these pregnant women is seeking advice about the management of her delivery. F Pregnancy could continue to await spontaneous labour The reason for her previous section is nonrecurrent so she should be able to have a vaginal birth this time. Spontaneous labour is preferable to induced labour in this situation because the drugs we use to induce labour – prostaglandin and oxytocin – increase the risk of scar rupture. Induction is not completely contraindicated, just less safe but you could induce if there were good maternal reasons, for example, pre-eclampsia. She is anxious because scan conﬁrms a breech presentation and she refuses to consider external cephalic version. B Elective caesarean section carries less fetal risks than vaginal birth The best option is external cephalic version because it reduces the incidence of breech presentation at term. If she won’t accept this, then the ‘Term Breech Trial’ showed that section is safer for the breech baby than vaginal delivery. F Pregnancy could continue to await spontaneous labour Although this woman has had diffculty getting pregnant, she should now be treated like any other mother. A Anorexia nervosa The distracter is pregnancy, which is the most common cause of secondary amen- orrhoea in teenagers, but the normal examination makes this less likely. I Pregnancy The mass could be an ovarian cyst but a granulosa cell tumour of the ovary is more likely to cause irregular bleeding than amenorrhoea and in any case they are extremely rare. Haematocolpos can also present with a lower abdominal mass, but the patient would have primary amenorrhoea, not secondary. You note that she has been admitted to hospi- tal twice already during the previous 3 months with pain and suspect that she is avoiding school as exams are imminent. Her younger sister also has frequent episodes of pain but attained menarche recently at the age of 14 years. D Haematocolpos Imperforate hymen can cause cyclical pain as the haematocolpos gets bigger and it is not unusual to fnd a couple of hospital admissions have occurred before the diagnosis is reached. Many teenagers have anovulatory cycles but this causes irregular periods and menorrhagia rather than primary amenorrhoea. She sees a poster about chickenpox in pregnancy on the surgery wall and realises that she was exposed to a tod- dler with chickenpox 6 weeks ago at a birthday party. F Reassurance that no action necessary The incubation period for varicella is 1 to 3 weeks so she would have developed it herself by now. A personal history of chicken- pox is 99 per cent predictive of the presence of serum varicella antibodies, so this woman does not even need testing for zoster IgG levels. She did have some routine screening tests when she started her job 6 months ago but was not given any results. It is still not recommended as part of a national screening programme to check antibody status and vaccinate all women in the United Kingdom like we do for rubella, but some occupational health departments do undertake this in high- risk groups such as teachers. If a woman contracts varicella in pregnancy she can become very ill with serious problems such as pneumonia and, of course, we worry about fetal varicella syndrome and infection of the newborn. For each patient pick the most appropriate investigation given the clinical information provided. She is not yet sexually active and her mother had similar problems before starting a family. C Diagnostic laparoscopy If she is not sexually active she will not have pelvic infammatory disease so the most likely diagnosis here is endometriosis, especially as it can run in families. Laparoscopy is the gold standard investigation as scan will not show up small deposits of endometriosis. She mentions that she has experienced severe deep dyspareunia for several weeks and wishes to stop using Depo- Provera® as she has read that it can cause low estrogen levels, which she thinks is responsible for her problem.
